Method: in the present study, the content and open, axial and selective coding were analyzed to identify the dimensions and components of the ecosystem based on the studies and policies of Patam Special Economic Zone. Internal studies were conducted by searching the scientific databases of Academy Jihad, Civilicia, Normags and Irandoc, and 33 second-hand data were identified and analyzed. Regarding the external indices they were scanned through Scopus.in 2008, when the first article with a keyword “ Entrepreneurship Ecosystem “ was presented in this index, 110 articles there were identified until 2018, and according to the number of citations above 10, 13 articles were identified and regarding the mentioned policies of the regulations of Ministry (Ministry of Information Technology and communications) about start-ups, general policies announced by the supreme leader, general policies of the resistance economy, Minister’s order to the regional director, the Constitution of the region were analyzed. Findings: It can be said that the present study is the first review study on the entrepreneurial ecosystem among national researchers and the results obtained from this research also show that the entrepreneurial ecosystem has a growing position, especially in recent years, among national and international researchers. The findings of the internal research represent that more than 70% of the studies were quantitative and servey type and most of them were analyzed based on Eisenberg (2011) model or global entrepreneurship indicators and most of the articles published with this keyword belonged to the Journal of Entrepreneurship Development, but the findings of foreign research showed other emphases. First, the articles presented with the reference number of more than 100 articles are included in review articles type and more than 70 percent of the reviewed articles including this keyword are qualitative. These articles themselves have followed their own special framework and theory. In this study, in addition to the above studies an attempt has been made to present a picture of policies and the role of the political environment, especially the effects of government policies on the mentioned study which is the special economic zone. Conclusion: The findings from the content analysis also depicted the identification of 107 initial contents which were finally categorized into four dimensions and 12 components. The output of the four-dimensional ecosystem software includes networking (consisting of university components, government institutions, politics) infrastructures (including culture components, support, education, physical and communication infrastructure and environmental features), commercialization (including market components and financial affairs) and self-creation dimension (including components of personal characteristics and human capital) were identified.

Each hand tools and digital applications, in the design process, have their own features and requirements and may somehow challenge the creativity in this process. So that students can take advantage of these technologies to try knowledge, ideas and demands with the mixed abilities. Creativity is a subjective process consisting of the ingenuity and flexibility and design process is based on creative developing that can be expressed by utilizing the tools of architectural design. During the design process, students thought acts like an intricate process of mental activity and interacts between creative and critical thinking. The main purpose of this study was to evaluate the relationship between creativity, architectural design tools, architectural design process and the success of these tools in the promotion of this ratio. Hence reviewing of the nature, type, status and application design tool in architectural design process and comparing their efficiency analysis to achieve creative defined in this study is very important. This paper has a comparative- analytical approach. So, after reviewing related literature, the research model have been developed. In the next step in a defined statistical community in a field study, the status and application of design tools in all phases of the architectural design process have been compared with each other about their various aspects and in this way the ability of each to promote creativity in problem-solving process in architecture, have been evaluated. The comparison have been carried out in two phases of qualitative (observation, interviews and document analysis) and quantitative (questionnaire) methods in architectural design studios, in academic and professional environments in Iran. Finally, summing up assessments conducted, the results of the research have been obtained with multiple comparisons. Based on qualitative research, taking advantage of different types of software, specially the kinds of synchronicity, have great success in design process and in the final stage of that. This option is relative in the first stage of the process and depends on the knowledge of Individuals towards software and their type. Quantitative analysis also has confirmed this findings and endorsed the active and effective role of software and the need to complete mastery over them, in architectural design process, both in faculties and professional communities. In the current era, the correct use of digital technologies in the process of architectural design, should be organized. Considering the systems development method of phasing models for different layers of architectural design, including digital technologies, and strategic planning for moving towards a dynamic and targeted structures can be helpful to promote skills related to subject, intellectual procedures and motivation in architectural design process.Therefore architectural design education with regard to the role of digital technologies and their comprehensive development, need to keep pace with all levels of strategic and practical plans to promote creativity in the process of architectural design in architectural studios.

15 - Usage of Multiple Qualitative Decision-Making Method of "DEX Expert Decision" in Architecture and Urbanism
Mohsen Dehbozorgi Alireza DaneshpourMultiple criteria decision analysis (MCDA) is a sub discipline of operations research that explicitly evaluates multiple conflicting criteria in decision making. MCDA are well known acronyms for multiple-criteria decision making and multiple criteria decision analysis; MoreMultiple criteria decision analysis (MCDA) is a sub discipline of operations research that explicitly evaluates multiple conflicting criteria in decision making. MCDA are well known acronyms for multiple-criteria decision making and multiple criteria decision analysis; Stanley Zionts helped popularizing the acronym with his 1979 article " MCDM – If not a Roman Numeral, then What?", intended for an entrepreneurial audience. MCDM is concerned with structuring and solving decision and planning problems involving multiple criteria. The purpose is to support decision-makers facing such problems. Typically, there does not exist a unique optimal solution for such problems and it is necessary to use decision maker's preferences to differentiate between solutions. "Solving" can be interpreted in different ways. It could correspond to choosing the "best" alternative from a set of available alternatives, where "best" can be interpreted as "the most preferred alternative" of a decision-maker. Another interpretation of "solving" could be choosing a small set of good alternatives, or grouping alternatives into different preference sets. An extreme interpretation could be to find all "efficient" or "nondominated" alternatives. Many "Multiple Criteria Decision Making" (MCDM) methods are available, which are often implemented by specialized decision-making software. One of the most important methods is the DEX method. DEX (Decision EXpert) Analytic Hierarchy Process is a qualitative and simple method that used to make decisions in situations where conflicting decision making criteria deal with difficult to make choosing between options. This method was first proposed by a Slovenian research group in 1983 and it has been used in many fields of science, including industry, health and housing up to now. DEX facilitates the following: - Acquisition of decision models, which are composed of: a hierarchy of attributes, and the corresponding utility functions that are defined by decision rules; - Consistency checking of decision rules; - Acquisition, evaluation and analysis of options; - Explanation of the evaluation results; - Group decision-making support. This article is extracted from the thesis "Design of Persian Miniature House with an Approach to Applying the Mystical Attitude of Iranian Painting". It has also tried to test the DEX method in the area of architecture; for this purpose, it is used in the site locating section. To select a site from existing sites, It needs components that are in line with the project approach and use. These are presented in the body of the article as an example. Now, in this context, can DEX be the target's answer? In this paper, a specific usage of this method is examined with an example of architecture, i.e. in selecting the appropriate location for the design of the project. The obtained results show that the DEX hierarchical analysis process method, which is done today with the help of software, regarding to be simple, flexible, using qualitative criteria and also the ability to review adaptability in judgments, can be used in simple issues, such as selecting a machine, to more complex issues such as the choice of land in architecture and urban projects, and to achieve the desired result.

Today, the problem of traffic accidents has become an important issue in Iran but all provinces are not same condition in this issue. Transport authorities and experts tend to know position of each state based on different criteria. They should know that which province has the good condition and which one are in the worst position because for more exact planning, this issue has some influences on their decisions. In this paper, provinces based on various criteria, equipment related to intelligent transportation systems, are ranked. This method indicates that the numbers of dead and injured are not appropriate criteria for ranking of states and different criteria must be considered. This priority is performed by using of Analytical Hierarchy process (AHP). Based on the obtained results, the most important indicators for assessing Iranian provinces to improve road safety are a number of relief bases, type of damage, intelligent transportation equipment and road traffic rate. Extracting the results was done using Expert Choice software. Manuscript profile -

Methodology: The factors identified from Technology Acceptance Model, Innovation Diffusion Theory and the study of Benlian & Hess (2011).The data were collected on top and middle managers using a structured questionnaire. A total of 370 questionnaires were completed. Results are analyzed by structural equation modeling, a path diagram generated and sixteen hypotheses tested using LISREL and SPSS software. Findings: five of the hypotheses were accepted. The results reveal that consumer behavioral intention for saas adoption affected by perceived consumer ease of use, marketing efforts and social influence. Research limitation: Other factors might have been identified and added to the conceptual framework. The timeframe of data collection was very specific. The large sample size and its apparent representativeness encourage confident generalization of the findings. Managerial Implications: marketers now have clear evidence that perceived consumer ease of use, marketing efforts and social influence are important factors that affecting consumer behavioral intention, and should plan their intelligence gathering and campaign strategy accordingly.

And when the demand for computer systems increased, the possibility of crisis and failure of the computer will increase. Thus, the reliability of computer systems has become a key concern for our life. According to The IEEE defines, software reliability is probability of failure-free software operation for a specified period of time in a specified environment. The problem is that currently most accurate method of software has error, and unfortunately still cannot completely prevent all errors. And software maintenance cost and elimination of errors is expensive, and even because of these reasons may be allowed error to remain in the system. This has reduced the reliability of the software. Previous solutions and procedures to enhance software assurance in various elimination forecasting and fault tolerance techniques has problems such as the complexity of formal methods (nominal) single version and version redundancy techniques, testing costs and the reuse of software code changes. The aim of this study is provide a method to increase software reliability and redundancy without the complexity of the software. In this study emphasize on the use of the capabilities inherent in the algorithm to reduce the complexity of software. Manuscript profile -

On the other hand, the Differential Interferometry SAR (D-InSAR) is an efficient way to continuously, accurately and in a wide range monitor land subsidence. In this research, the D-InSAR method was used in the study of land subsidence in Arak city. 14 single-look complex images were obtained in the range of C-Band by EOLi-sa software. Ten processing steps were done by the SARscape software based on the four interferograms which had both the time and space criteria. On the other hand, the National Cartography Center has repeated the observations of the first-class network of the country for the city of Arak, located on the BHBT route (Borujerd-Salafchegan) in 1985 and 2004 and it measured 190mm ± 0.8mm / km of subsidence in 19 years. Based on four geocoded reflated unwrapped interferograms, the subsidence rate was calculated about one centimeter at year, for the central regions of Arak (around the Shohada Square of Arak). The urban areas had also almost identical subsidence rate. Therefore, the results of validation of the D-InSAR method using the observations of the National Cartography Center confirmed appropriate accuracy of the D-InSAR method. The results of this study showed the impact of geological and water resources factors on subsidence and the necessity of protecting water and soil resources in development projects in Arak city.

The objective of this study was to evaluate the OILCROP-SUN model for Euroflor hybrid of sunflower in order to gain a suitable base to conserve soil and water resources. This study was conducted as a strip-plot statistical design with randomized complete blocks design with three replications for each treatment. Total biomass, seed weight, seed yield, percentage of seed oil, and seed nitrogen were measured. Using collected field data, OILCROP-SUN model was calibrated and evaluated for different levels of water and nitrogen applications. Six genetic coefficients were then derived from calibration of OILCROP-SUN model for Euroflor hybrid. The results indicated that seed yields were simulated reasonably well for 12 treatments with NRMSE value of 18.5%, and the d-index of 0.92. The d value of different treatments of water and nitrogen for seed nitrogen was 0.93, and for oil production per hectare was 0.91. Manuscript profile -

Breakage of earth and rockfill dams and also too much volume of torrential flow can destroy catchment areas and fen beds. Furthermore, correct designing of dams and obtaining suitable safety factors will prevent of these damages. In this study, first of all, series of geotechnical tests have been performed on the soil samples of the Chitgar earth dam to determine the soil strength parameters and material characteristics. The achieved parameters have been used as input parameters for PLAXIS which is a finite element geometrical program for analysis of deformation and stability of soil structures. Based on different layers of foundation and dam body, four homogeneous and non-homogeneous models on coarse and fine foundations have been simulated and the results have been compared. These comparisons revealed that during construction of earth dams, which are situated on fine clay foundation, if the water level is high, there would be lots of pore water pressure which will cause the dam foundation to be destroyed. Therefore, dam must be constructed using step-by-step method so excess pore water pressure can have enough time to be lessened. The analysis, which carried out on non-homogeneous earth dams with clay cores, discovered that if dam construction is simultaneous with water filling, there would be high pore water pressure in the earth dam’s core which will reduce the safety factor of the dam. Therefore, it will be better if the non-homogeneous earth dams are filled after the construction period. Finally, sometimes in loose foundation, safety factor was found 1.45 for homogeneous dams in the stepped construction. The safety factor was estimated 1.14 non-homogeneous dams in the same conditions. Therefore, homogeneous dam can play better role than non-homogeneous dams in loose foundation. Manuscript profile -

Understanding of this behavior in drip irrigation system is a real task for researchers. The geometry of moisture pattern created by trickles in soil is one of the important criterions in drip irrigation system. Several important parameters such as soil hydraulic functions, drip discharge and irrigation time directly influence the dimensions of created wetting front. The objective of this study was to determine the wetting front dimensions created by point sources. For examining HYDRUS-2D software capability, a T-tape drip irrigation method with 2.388 cm/hr discharge and maximum depth of 70 cm was conducted in the Urmia University experimental field. At the end of irrigation experiment, the water distribution condition in soil was determined by gravimetric soil sampling method. When performance of simulation model confirmed to be accurate enough for simulation purposes, six different discharges with trickle function of maximum 30 h, was conducted by the software. Some simple relationships were obtained by using Buckingham π theorem. These equations determinate the depth and maximum diameter of soil by using soil hydraulic conductivity, drip discharge and irrigation time. The obtained correlation coefficients (0.993 and 0.970) and mean absolute error values (1.177 and 1.706) for determining the depth and maximum diameter of soil confirmed the capability of these semi empirical equations for calculating moisture pattern geometry dimensions. Consequently, these derived equations can be used for design and optimal management of drip irrigation system in the studied conditions. Manuscript profile -

Therefore, a normal and an inevitable part of any hydrological or water management project before starting the research is analyzing the accuracy of time series. For this purpose by using statistical tests, the time series are analyzed heterogeneous and improbable fluctuations of data and if needed are corrected or omitted. Although usually passing the statistical tests, scientifically verifies the efficiency of the data, more precise verifications on the data may lead to different results. Therefore, in this study by choosing precipitation data of Urmia basin as a case study, final results of some statistical tests on the efficiency of the data are analyzed. Careful and precise analysis of the time series especially in comparison with neighboring stations shows that full reliance on the statistical tests alone is not enough for analyzing the efficiency of the time series and the results of these tests may mislead users on the true condition and efficiency of the data. Based on the results of this study, only 2.4 percent of the data need correction or must be omitted; nevertheless, more precise analysis through data shows that about 12.6 percent of the data are completely unsuitable and must be omitted.

Meanwhile there are some worries about the environmental impacts of creating green roofs, as despite the benefits of vegetation, some layers of green roofs like waterproof membrane, are made from polymers. In this survey, environmental impacts of an extensive green roof in its lifetime were compared with a normal roof. Materials and Method: In this survey, life cycle assessment method was used. Since there are various methods to implement a green roof, first different methods of implementation and different materials that can be used in its layers were studied and collected. Then some of these methods were chosen to investigate their environmental impacts in order to find the optimized option to create a green roof. On the next step, life cycle assessment of optimized option and normal roof was conducted. The open LCA software was used to compare environmental impacts of different implementing methods, and also optimized option and normal roof. Results and Discussion: Results showed that the green roof has less environmental impacts than normal roof, during its lifetime. In addition, it was indicated that in some impact categories that the environmental impacts of green roof was more than normal roof the reason was using PVC and geotextile (glass fiber and polyester) in its layers. Results of this paper can be improved by measuring benefits of creating a green roof (such as reducing quantity and quality of run off amounts), and also using materials with less environmental impacts in green roofs layers.

Apart from energy efficiency considerations, the importance of using daylight in educational spaces is due to the pivotal role of light in visual perception of students and quality of educational spaces. This article addressed light shelves as window attachments with effective role in desirably lighting a classroom. Given the function of light shelves in clear and sunny climates and high number of educational centers in Tehran, this geographic area was selected to be investigated. Method: This research was founded on data from previous studies to determine the suitable depth of interior and exterior light shelves for window day lighting in this city. In this quantitative study, six types of light shelves with different layouts and heights from the floor were defined, and Diva for Rhino was used for simulation. These six light shelf layouts were analyzed by this software to determine the best one for providing the optimum day lighting. Performance of the light shelves was tested through simulation and their effects on the amount of light in a simulated classroom were examined. Findings: Results showed that all six light shelf layouts made the level of illumination bounce up and reduced energy consumption. Since the south side receives the most sunlight, south-facing light shelves are more efficient. Discussion and Conclusion: According to software simulations, the best results in terms of even illumination and glare reduction are achieved by using intermediate light shelves positioned 240 cm away from the floor (Type 1).

The e MoreBackground and Objective: Today, metropolises play a very important role in environmental pollution, increasing population is associated with increasing consumption of fossil fuels and energy resources, which increases greenhouse gas emissions into the atmosphere. The effects of increasing greenhouse gases with the occurrence of greenhouse phenomena cause climate change. Due to the high energy loss in residential buildings, The purpose of this study is to select an appropriate solution to optimize the building and reduce energy consumption in this sector. Material and Methodology: In this research, first, the annual energy consumption of a type of 8-storey residential building in Tabriz was simulated using Energy Plus software. Then, the annual energy consumption of the building was simulated with the weather conditions of two different climates of Yazd and Rasht to compare the energy consumption of the building in all 3 cities. Then, with JePlus simulation software, the energy consumption of different building modes (orientation, position, temperature, climate) was simulated in all 3 cities to study the behavior of the building in terms of energy consumption. Finally, the amount of heating and cooling energy consumption of the building was selected as the target functions and optimized by JePlus + EA software. Findings: According to the variables defined in the input of JePlus software, 432 energy consumption modes were obtained for the building. And according to the selection of heating and cooling energy consumption of the building as target functions, optimization was done by JePlus + EA software. The optimization results showed that according to the same parameters considered for all three climates, building energy consumption in Rasht has decreased by 16%, Yazd by 14% and Tabriz by 12%. Discussion and Conclusion: The results showed that if the building is built in the right direction and position according to the type of climate and weather conditions (for sunlight, temperature, humidity, etc.) and the heating and cooling temperature inside the building is set to comfort, The energy consumption of the building is also significantly reduced As a result, the share of each building in the amount of carbon dioxide emissions into the atmosphere, which is the most effective gas in climate change, is reduced.

The main purpose of the present study is comprehensive management and planning in order to use the existing water resources of Yamchi dam network located in Ardabil province and meet the demand in the drinking, agriculture, industry and environment sectors, taking into account their future needs.Accordingly, Yamchi dam and its downstream areas are simulated in the WEAP model environment and the model is implemented for current conditions and future development projects in ten different scenarios. The proposed scenarios included examining the impact of allocation, industry needs, increasing irrigation efficiency, removing groundwater resources, changing cropping patterns, single cropping, and combined scenarios. The entries included information on the Yamchi dam and reservoir, groundwater resources, and the parameters needed to calculate the nodes for drinking, agricultural, industrial and environmental needs in the period 2008 to 2018.Findings: The results showed that among the proposed scenarios for the areas under study, the scenario of simultaneous change of cropping pattern and 65% increase in irrigation efficiency is the most suitable option among the studied scenarios, which meets time and volume reliability of drinking and agricultural needs by 100% and will reduce the needs of the current situation by 44%.Discussion and Conclusion: It is worth noting that if the groundwater source is eliminated for any reason, none of the solutions of changing the cropping pattern, increasing efficiency, etc. can fulfill the shortage and it is necessary to treat urban, agricultural and industrial wastewaters and reuse one of them. The results show that urban wastewater treatment and reuse can provide about 60 percent of the shortage of groundwater resources. Manuscript profile -

Provid MoreBackground and Objective: Reducing fossil energy resources, the environmental impact of high energy consumption and increasing the energy consumption in the building section, has increased the importance of attention to building energy consumption in the country. Providing the standard of building energy consumption in our country is one of the important activities in this regard. This study aimed to determine the effect of different strategies to reduce energy consumption in the energy classification of office buildings as a case study by Design Builder software. Method: In this study, the total energy consumption of of an office building in Semnan climate was simulated by Design Builder software and the results obtained by the software, with the actual energy consumption of the building in 2016, which was obtained from the energy bills (electricity and gas) of the building, were validated. Then, using the energy rating of building, different strategies for reducing energy consumption were simulated and compared with the existing situation. Findings: Using energy simulation software, various energy efficiency strategies such as using external horizontal shading and removing internal shading, replacing windows with low-emitting double-glazed windows instead of single-glass windows and installing a thermal insulation in the external wall of the building were investigated that 15.2, 18.4 and 8.2% reduction in energy consumption achived compared to normal case, respectively. Then, the intensity of building energy consumption for each of the proposed strategies were calculated and the energy rating was determined for each. Discussion and Conclusion: The results showed that the replacement of external shading instead of internal shading had the least amount of savings and had no effect on the change in energy rating and the use of a combination of double glazing instead of single-walled and thermal insulation in the outer wall of the building while upgrading to the classification, the optimal suggested mode. Finally, the results of this study showed that in the case of accurate simulation of existing buildings and then validation the effects of different strategies on energy rating and consumption can be predicted accurately.

Determination of the geometry of the watershed and stream network extraction and analysis of physiographic parameters for morphometric analysis, is the most important step for hydrological applications. Method: Using DEM with 10×10 meter pixel size of Sarbaz watershed, was extracted physiographic parameters such as environment, area, branching ratio and drainage density using software ARCSWAT, HEC-GEO HMS, WMS and ARC HYDRO and was compared with watershed border area. Findings: The results of SPSS showed that they don’t have statistically significant differences in the level of 95% between operations of software. So, the results of Duncan test represented that all softwares are placed in a group. Output parameters of the software in numerical terms was very close. Depending on the expert opinion and ease of use of any of the software can be used to derive physical parameters of watershed. Although the border area of extracted with ARCSWAT, HEC-GEO HMS and ARC HYDRO was closer than WMS with the truth visually. Discussion and Conclusion: Because of pre-processing process required the preparation of DEM in WMS software and the difficulty with this software compared to other software, WMS software less frequently used in hydrological studies. But in hydrological studies such as flood control, sediment and erosion due to consideration of more ranks of stream the WMS software could be more appropriate. Manuscript profile -

One of the ways to select conservation areas with high biodiversity is to use Marxan software. The aim of this study was to determine suitable conservation patches with high biodiversity by Marxan software and to identify conservation patches under the pressure of pollutant hotspots in the coastal area at the western part of Hormozgan Province. Material and Methodology: In order to identify the conservation areas with high biodiversity, simulated annealing algorithm of Marxan software was used in two scenarios and for this purpose, 36 protection criteria were examined. ArcGIS 10.3 software was also employed to determine the distributions of plant and animal species, as conservation criteria, pollutant hotspots and the existing protected areas. The conservation patches under the pressure of pollutant hotspots were identified by integrating the results of the selected scenario into the map of pollutant sources. Findings: Results of Marxan software which was done in 2020, revealed that the selected conservation areas and the existing areas protected by the Department of Environment were not compatible in terms of biodiversity conservation, nearly 801349 hectares was required to protect 50% of each conservation criterion (second scenario), and the pressure of industrial centers on the eastern and central parts of Kal-Mehran basin should be reduced. Discussion and Conclusion: Since the second scenario covered all the conservation criteria, except for one criterion, it was considered as the best scenario for achieving the conservation goals. Integration of the results from the second scenario into the map of pollutant resources indicated that the conservation patches at the eastern and central parts of the study area were under pressure. Therefore, it was recommended to expand the current protected areas towards the western parts of the study area. Manuscript profile -

A large percentage of rainfall in different areas under the influence of factors such as geological structure and structure, vegetation, land slope and the shape of the basin becomes surface runoff. Floods are also the result of runoff caused by heavy rains with sudden melting of snow. In catchments, it is not possible to measure all the quantities required for runoff analysis, so it is necessary to choose a model that can easily predict the runoff from rainfall while using simple structure and minimal factors. arrives Material and Methodology: In this study, using simulation of rainfall to flood conversions in a long statistical period of about 20 years between January 23, 2000 to September 23, 2021 in the Astana-Kuchesfahan catchment with HEC-HMS software, one of the objectives The effect of selecting the type of flow conversion hydrographs on the amount of computational error in flooding was investigated. Findings: In this study, unlike the SCS method, in which the error digit as a Nash function is 0.540 and the RMSE is 0.7 as well as the deviation percentage with a digit of 28.01, for the Clark method the Nash function is The value is 0.533 and RMSE is 0.7 and also the percentage of deviation is 29.71. Also in Schneider method, Nash function is 0.477 and RMSE is 0.7 and also the percentage of deviation is 34.25. Discussion and conclusion: This calculation also confirms in terms of error measurement that one of the best criteria for observing the difference can not be RMSE. By performing the validation step, the amount of initial error on the set was significantly reduced. This value reached 0.595 during the long 20-year period for the Nash function. Also, for all the elements in the model, the flow volume and discharge at the moment of the peak event improved significantly. The correctness of the model in the calibration step to reduce the error confirms that selecting one type of hydrograph for the range does not necessarily lead to a significant reduction in the simulation error. However, the converted hydrograph type is significantly effective in reducing the calibration error. Manuscript profile -

Method: First, manning number of the river is estimated as 0.018 by integrated hydraulic modeling of the river and its water channels. Then, dispersion factor of the river is calculated as (v: velocity) by solving Advection-Dispersion equation. Modeling of water quality parameters, such as dissolved oxygen, nitrate, ammonia, BOD and temperature, is performed using ECOLAB module in the MIKE11 software. The major parameters in the water quality model are determined using sensitivity analysis. These parameters were calibrated and the calibrated model is verified. Findings: The results showed that the water channels behave as complete mix systems. Conversion coefficients of water quality parameters are calculated, and then the average values of salinity, dissolved oxygen, ammonia and nitrate in the channels are calculated as 27000, 3, 3 and 5 ppm, respectively. In addition, these parameters in the river are about 5300, 2.2, 1.2 and 11 ppm, respectively. The correlation coefficient of developed hydraulic model in verification step is 0.95 and the percent of absolute error of verified salinity, dissolved oxygen, temperature, ammonia and nitrate models are 7.9, 12, 1.2, 0.79 and 0.34, respectively. Conclusion: The results demonstrated the capability of MIKE11 for water quality and quantity modeling in tidal rivers. Manuscript profile -

Therefore, modern solid waste management is necessary to overcome the created problem. Such management should carefully consider various aspects of waste generation, storage, collection, transport, recycle and final disposal. Among these, one should admit that the higher cost of waste management belongs to transport of wastes. This includes both collections from residential areas, their transportation to transfer stations and finally transport to the landfill. In the present investigation, municipality No.22 of Tehran city is selected to examine cost of transport using WAGS software. The results show that the highest percentages of total transport cost is allocated to the wages of personal (almost 74%). The other components such as vehicles, repairs, full and others have a share of 16, 6, 3 and 1% of the total cost of collection and transporting of solid wastes. The overall expenditures of waste collection are about 44140 million Rails which indicates the need for additional investment equal to 36470 million Rails to the year 2020. At present the cost of collection and transportation of wastes to the transfer station is about 75 Rials/Kg. This amount encompasses all personal, vehicles, fuel and other associated costs. It is estimated that above mentioned cost increase from 75 to 81 Rials/Kg in the year 2020. At present each family has to pay 85640 Rials/year as a cost of collection. Manuscript profile -

While on the other hand it can be an indication of a drastic escalationin energy consumption owing to low national energy prices which does not oblige industries or otherenergy consumers in general to follow efficient energy consumption patterns. The lack of suchapproach toward consumption has resulted in enacting a series of rules with the aim of economizingconsumption. An efficient tool in planning economical consumption methods is auditing softwarewhich renders help to authorities in regulating the consumption. A matter of significance in ourdiscussion is the status of software-based analysis of energy auditing in construction industry and theneed for such software's.

Contrary to public perception in these areas the water quality is more important than quantify. Therefore, monitoring of water quality and identification of pollution sources is one of the main concerns of researchers in this area. In this study, in order to identify sources of groundwater contamination, areas are likely aquifer recharge sources of Tehran-Karaj plain detected. So, after extraction of groundwater level data different interpolation and geostatistics methods are used to create surface images. The Gstat software and Geostatistical Analyst were used for this study then performance and ability of each one to produce surface images are evaluated. According to the results, the Geostatistical Analyst software has better flexibility to do the special analysis. Based on the training and test data interpolation methods were very similar, but the surface images regarding groundwater direction flow and histogram look very different. According to the results, universal kriging showed better performance. Accordingly, surface images of different time created by an appropriate method to simulate groundwater flow direction and eventually areas were identified which are more likely ground water recharge source of Tehran-Karaj aquifer.

In fact, the improvement of the urban space should seek to increase social interactions instead of separation. But Moresuccess rate of urban spaces, especially modern commercial complexes, is proportional to the amount of use of that space and the presence of people in it. In fact, the improvement of the urban space should seek to increase social interactions instead of separation. But what we are facing today in most of the urban spaces is the reduction of relations and social participation of the residents in these spaces. In this research, the evaluation of social effects is proposed based on the fuzzy matrix. In building the evaluation matrix, the main activities of the project in the exploitation phase, as well as the important social and cultural indicators, are determined using the fuzzy Delphi method, and the importance of each effect is estimated in the form of triangular fuzzy numbers. The results of the evaluation based on the proposed model show that the sub-index of "setting the environment for family presence in the urban space" with a score of 0.754 has the highest effectiveness from the activities of the modern business and entertainment complex. Among the effective activities, "the place of construction of the commercial complex" with a score of 0.784 had the greatest effect on the sub-indices of social interactions. As a result, based on this social impact assessment model, in order to promote social interactions, it is necessary to adopt the necessary strategies and policies in the field of family presence in modern commercial spaces, as well as the appropriate location of the construction of these complexes.

Wave propagation inside the building is one of the most challenging issues in network design and optimal location. Different parts of the building have different effects on the propagation of waves inside the building, such as fading, scattering and propagation of waves in several directions. Due to the nature of electromagnetic waves, the metal parts of the building have a great effect on the propagation of waves. In this paper, the effect of different metal parts of the building, including beams and door and window frames in standard dimensions, on the propagation of WIFI waves using Ray Tracing algorithm and CST software is modeled, and propagation patterns for different angles and distances are obtained. With the using of CST software, various modes such as rooms with different dimensions can be modeled. Then, based on the results, calculate the best location for the receiver. The results show that this method provides better capabilities than statistical methods to determine the best location of the receiver in the building. Manuscript profile -

This method reduces Capex and Opex costs due to its software and low hardware dependency. Software-centric networks and virtualization of network functions have been introduced in the computer networks arena as a new way to design, deploy and manage network services. Those can provide more flexible and more flexible and adaptable to the consumer and provider according to the needs of end users and service providers to consolidate and deliver network components using standard IT virtualization technologies. This paper presents the architecture and prototype of a video streaming service compatible with SDN / NVF-enabled networks, allowing simplified networking and applications and reduced management costs.Method: The simulation framework of this paper conforms to the MANO architecture to implement the standard NFV evaluation method. In CloudSim, each simulation occurs by sending and receiving events between modules.Results: As expected, NoScale-Min policies in both LFF and MFF methods lead to exceptionally long response times due to resource shortages in VNFs. On the other hand, the delay of the NoScale-Max policy is short due to resource constraints enough is assigned to the VNF.Discussion: In this paper, we proposed CloudSimSDN-NFV as a framework for new simulation tool of video streams to evaluate NFV features in edge and cloud environments along with other features of SDN and cloud computing environments. This framework is designed and developed on CloudSimSDN. We describe the modeling and simulation of NFV and edge computing and the detailed design and implementation of our framework. Two used scenarios were presented to help understand how to use the new tool, and several algorithms were implemented and evaluated based on the framework. Manuscript profile -

Consequently, the explosion of new network applications and services has strained the capabilities of traditional networking architecture in terms of scalability, agility, and efficient traffic management. SDN (Software Defined Networking) is a novel approach to build networks in which control logic is decoupled from data forwarding in order to enable programmability and ease of configuration across the entire network. The centralized control in SDN provides a global view of the entire network resources and their performance which enables the innovation of new service models. This paper demonstrates the implementation of SDN in a sample data center network topology using Mininet and the RYU controller, followed by employing policy-based network management and a differentiated service mechanism for guaranteeing the QoS for different classes of traffic. The proposed framework is a foundation to develop an enterprise-level network control and management product. Method: The approach of this paper is an implementation of a software-based architecture in the topology of a data center. It manages and guarantees the quality of service, using network policy-oriented management and service quality methods. The presented framework is an expandable infrastructure to solve the challenge of dynamic and agile management in the network of data centers and virtualization and cloud processing service providers.Findings : With the implementation done, h1r1 server node listens on ports 5001, 5002, 5003 with UDP protocol. The h1r4 client node sends 1Mbps UDP traffic to port 5001, 300Kbps UDP traffic to port 5002, and 600Kbps UDP traffic to port 5003 of the h1r1 server. The results obtained using the IPerf3/JPerf tool show that for traffic marked with AF41 code sent to port 5003, minimum bandwidth of 500Kbps and for traffic marked with AF31 code sent to port 5002, minimum bandwidth of 200Kbps is guaranteed. Is. When sending traffic of AF classes, the bandwidth of the best-effort traffic sent to port 5001 is limited.Conclusion: Guaranteeing full quality of service for all types of applications is not possible with the current network architecture based on the best-effort model. Different applications have different service needs that require dynamic management of network resources. In this article, a solution based on SDN architecture was presented for service quality management, which uses a differentiated service model. Differentiated service mechanism allocates resources based on different traffic classes. In this method, all streams belonging to a class are routed equally. The results obtained from the simulations show the optimal performance of the introduced framework in meeting the needs of traffic flows and optimal and maximum use of network resources.

Power system planning and operation, power network reorganization, and many optimization s MoreIntroduction: Load distribution analysis is a fundamental and basic study for all power networks, including distribution networks, which are used in steady-state conditions. Power system planning and operation, power network reorganization, and many optimization studies require a large number of load distribution calculations in normal and emergency situations. Due to the nonlinearity of the system of load distribution equations, it is necessary to use iterative solution methods to solve it. In addition, due to a large number of power grid buses, matrix algebra is used. Some of these applications require fast iterative solutions of load distribution and therefore it is very important that load distribution analysis is performed efficiently. A number of load distribution algorithms are specifically designed for distribution systems. One of these methods considers bus voltages as state variables and works based on an iterative algorithm and uses special methods to increase convergence.Method: The proposed algorithm of this paper called SDLF in this article does not need special matrices and complex programming. In this method, load distribution can be achieved easily with only a simple vector that shows the priority of buses, which we call BPV, and by using the forward-backward sweeper algorithm. It is worth mentioning that the BPV vector itself is extracted from the network topology. This work can be done both visually from the electrical diagram of the network and from the data matrix of network D by MATLAB software. Finding: In terms of the convergence of the solution, increasing the repetition has led to an increase in accuracy, and as a result, the 10th repetition has been chosen as a relatively accurate result to confirm the validity of the method, considering the required engineering precision. The obtained results show that even in the first iteration, an acceptable accuracy for the voltage range has been obtained. In steady state analysis of power networks, the voltage amplitude is more important than the voltage phase. The noteworthy point is that in calculating the voltage phase, it is not necessary to update its value in each step, and it is enough to calculate the voltage phase after obtaining the voltage ranges. Conclusion: In this article, a new method called SDLF is introduced to study the load distribution of distribution networks. The results of the implementation of the proposed method, with an acceptable engineering error, can be used in the common applications of power networks in the first iteration, and based on this, it can be used as an online load distribution in SCADA systems. The effectiveness of the method was checked on the test network of 33 IEEE buses in the text of the article and its validity was confirmed. The introduction of the BPV bus priority vector made it possible to avoid using complex matrices and additional calculations and to reduce the time of load distribution calculations.

Identifying a trusted node fro More Background and Purpose: The main purpose of software-defined networks is to separate data from the control. That is, the elements are obtained through centralized remote controllers, rather than through distributed control protocols. Identifying a trusted node from an unsafe node is also one of the challenges in this area. By finding and removing malicious nodes from secure nodes, packets are re-sent and energy is prevented, and network life is increased. On the other hand, the existence of hostile nodes to collect information or destroy sensitive data, as well as disabling the network and disrupting it in various ways, has made this area of great importance. In cases where the workspace and environment are secured, the sensor node may become a selfish node for the rest of its life, refusing to send or receive information. In this way, the data that exists in the previous path to the destination node will never be collected and without trust management, the validity of the received information will remain unclear. Therefore, the failure of a sensor node or its death due to lack of energy should not cause failure or disruption of the entire network, and the existence of various routes to send data using the calculated trust can be considered as a way to do this. Even so, they are often controlled in a distributed way. However, their potential challenges are more complex and can theoretically be solved with better network knowledge. In software-defined wireless sensor networks, security and energy are two critical issues. However, few studies have provided these two aspects simultaneously. With the widespread deployment and use of sensor networks, security and trust management issues are becoming a major concern. So far, the main focus of different research has been on building practical and useful sensor networks, with less emphasis on security.Methods: This research examines the security challenges in software-defined wireless sensor networks and summarizes the key issues that need to be addressed to achieve security. In this study, sensors were studied that, to conserve their energy, became selfish nodes and refused to receive or send data. Trust in such nodes will be discussed through the four criteria of honesty, intimacy, energy, and humility. In this regard and as the first step, the clustering is taking place by a software-defined network, to cluster the number of distributed sensors. For this purpose, the combination of two algorithms, which are k-means and kNN, is done based on the number of sensors used by the software-defined network, and then the optimal routing, which is based on energy consumption and trust priority is considered.Results: The proposed model is deployed for three different scenarios, with 50, 100, and 200 sensors with random distribution. Furthermore, some safe methods for achieving security in wireless sensor networks are described, and finally, a proposed integrated approach based on trust to ensure the security of sensor networks is presented.Discussion and Conclusion: The results of this study show that the proposed model has been able to have optimal energy consumption due to building trust.

Software-defined networking is one of the most promising modes of future Internet development due to their centralized planning and management capabilities. The load balancing problem for distributed SDN controllers is one of the fundamental challenges of these networks, and a single centralized controller may cause reliability and scalability problems, and although several controllers can solve these problems, a flexibility mechanism is required for load balancing.Method:Therefore, in this research, a load balancing mechanism is proposed based on the load information strategy, so that each controller in the system periodically reports its load information to other controllers, and the overload controllers of the plan, load infomation They do not collect all other controllers before local decisions are made, which in turn reduces controller resource consumption. A load balancing strategy is proposed in the proposed response time-based scheme for multiple SDN controllers, which takes into account the real-time response time characteristics that change with the controller load. Another key part of the proposed scheme is that all these things are done in the Ryu controller by choosing an appropriate response time threshold and processing multiple overload controllers simultaneously, which can solve the load balancing problem of the SDN control panel of the overload controller well. slow This model proposes to transfer the management of specific switches between controllers.Results: In the simulation, the historical load and the future load of the switches were considered, and a switch migration algorithm with double weight was proposed, which led to a decrease in the frequency of switch migration. Experiments have proven that this scheme can quickly provide load balancing between controllers and reduce the number of switch migrations. The results showed that this design can lead to the migration of the overload controller and quickly reduce the workload of the overload controller. As a result, the proposed scheme can effectively achieve load balancing of multiple SDN controllers with high speed. Manuscript profile -

Ferdowsi Shahnameh is one of them. One of these topics, in which the important parts of this great book have a significant presence due to its epic nature, is the mirrors, techniques and tools of warfare, about which no research has been done so far. Combat tools play an important role in the creation of artistic images, as they have been used throughout the Shahnameh, both in describing battle and battle scenes and in describing feast scenes. Masnavi "Tools of War", the work of Vahid Qazvini, is one of the poets of the 11th and 12th centuries AH, which has eight hundred verses and is written to describe the tools of war. This research seeks to compare the Shahnameh and Masnavi of Mirza Mohammad Taher Vahid Qazvini's war instruments in a descriptive-comparative manner. The results indicate that there is a significant difference between the creation of imagery and tool warfare in the heroic part of Ferdowsi Shahnameh and Masnavi descriptions of Mirza Taher Qazvini's war tools. Since no research has been done on this Masnavi so far, the author intends to introduce this poet and study this work and compare it with Ferdowsi's Shahnameh and identify their similarities and differences and the extent and how this poet is influenced in describing the war of tools from Shahnameh.

As the early years of training play a fundamental role in the physical, emotional, moral, and rational structure, they are of great importance and the role of the family in these years is so distinguished. As one of the family pillars, the father does not have any substitutes. Children acquire the first affection, friendship, hatred, and hostility lessons at home. The role of the father is highly outstanding in the family because he is the main person responsible for the proper training of children. This research aims at investigating the educational role of the father in the teachings of Nahj al-Balaghah. The study was done with the descriptive-analytical approach and gathered library data, in particular Nahj al-Balaghah and Imam Ali's (A.S.) sayings related to the role of the father in training children. Thus, qualitative content analysis was used to analyze Nahj al-Balaghah. The ATLAS.ti software was used in this study to code, classify, and categorize selected texts. After the Nahj al-Balaghah statements related to the research subject were collected and coded, in total 571 codes related to the training and father themes were extracted from which 53 were about the training and father codes. Summarizing and incorporating Nahj al-Balaghah codes and classifying them leads us to six titles of the factors that influence training. Dashti translation of Nahj al-Balaghah was used for coding this book. Keywords: ATLAS.ti software, Family, Father, Nahj al-Balaghah, Training IntroductionIntroduction: Training means leading (Beheshti, 2019). From the training point of view, a father is regarded as a leader and a teacher, a practical and intellectual mentor, and a behavior model. The roles that people played in families in Imam Ali (A.S.)'s era were different from those in current families. In Imam Ali (A.S.)'s era, the father played a substantial and vital role in the family, was the manager of the family's production, and since his living and workplace were close to each other, he could better supervise his family. However, nowadays the living and workplace are far from each other and the father can't spend much time with his family and children (Aron, 2014: 30)."Training from Ali's Point of View" by Majid Rashidpur, "Training and Education in Nahj al-Balagha" by Majid Fuladgar, "Mah-e Mehrparvar", "Training in Nahj al-Balagha", and "Taer Farrokhpey" by Mostafa Delshad Tehrani, and "Social Training and Professional Training in Nahj al-Balagha", "Effective Factors in Training from Nahj al-Balagha Point of View" by Najme Vakili are all written in this regard.This study aims at investigating the role of the father in Nahj al-Balagha doctrines. Thus, the descriptive-analytical method is used to study the role of the father in training children from Imam Ali (A.S.)'s point of view. MethodologyThis research is applied in terms of purpose and uses the content analytical method. All of Nahj al-Balaghah was used as the statistical population and the ATLAS.ti software was used for extracting 2345 codes. Fifty three codes that referred to the role and position of the father were chosen for this study. ResultsAnalyzing the quantitative data of the factors effective in the father's role in training from Nahj al-Balaghah's point of view was the basis of testing the research hypotheses. It is worth mentioning that we tried to rely only on analyzing the quantitative data of extracting the categories from the chosen Nahj al-Balaghah text; in other words, we didn't use our personal opinions to obtain the results. Since without mentioning God and relying on divine training, the heart is destroyed and humans fall into the bottom of the well, the father must take care of his children to invite them to divine piety and polish their souls with advice and suggestions. DiscussionThe study investigated the role of the father in the family based on the teachings of Nahj al-Balaghah. The results indicated that when training his children throughout their childhood and teenagehood, the father must advise his children based on his love for them, and he must teach them self-improvement principles and walking with God, so that they avoid worldly whims, remove distracting hobbies, and think of the hereafter journey without any negligence.The study results are in line with the results of Salehi Babamiri & Faraji (2019), Alavi (2014), Zohadat (2011), and Siers (2012) studies. In his research, Mirzabeigi (2015) concluded that the father is the main responsible person for establishing order and security, enforcing the law, and planning life matters at home; therefore, as the children get older, their need for their father gets more essential and more vital. ConclusionStudying the results of some research that was done in the 1990s, we conclude that:Although the child models many people in his life, the father can be a suitable model for him at all ages. The child models many ethical vices and virtues from his father. The role of the father in the family and training children is considered so important in educational psychology that his ethical and personality characteristics may be found out through his children's behaviors.Nowadays, one of the reasons for the families' weakness is the reduced role of the father in the family. Children who are grown up in their father's absence are more susceptible to crimes.Acknowledgments The study is extracted from the Ph.D. dissertation at the Islamic Azad University, Sanandaj Branch.

Then, according to this velocity and flow rate in the main branch, the diameter of the duct and the corresponding head loss are computed. Here, for the rectangular ducts, the dimensions are found taking into account the limitations in the height of the duct. Thereafter, the diameter of the duct (or the dimensions of the rectangular duct) are calculated in other branches according to the flow rate in each branch as well as the head loss in the main branch. Finally, the fan head is obtained based on the head loss in the branches having the highest losses. It is obvious that change in the conditions in accompanied with the repetition of the computations. To remove this shortcoming, in this work, an alternative method is proposed through coding in the EES software. In this method, the branches are input to the code once. Then, with any changes in the conditions, the code is required to be run once more. To demonstrate the suitability of this method, it is utilized here for the design of a typical ductwork. Thereafter, a parametric analysis is undertaken to examine the effects of the duct height as well as the velocity on the main branch on the area of the consumed plate. This analysis is based on the response surface method. Manuscript profile -

Smoke is generated after a fire. Smoke from fire poses a greater risk to life than fire. By controlling the smoke, the building and its occupants can be protected and the damage caused by the fire can be reduced. In this study, smoke distribution and temperature profiles in the parking lot of a commercial complex were investigated using Pyrosim software. Navier-Stokes equations for energy, Conservation of mass were used to solve, and Large Eddy Simulation model was used for turbulence. Two scenarios were considered to investigate the fire. In the first scenario, parking without a ventilation system was studied and in the second scenario, it was studied with the ventilation system. Exhaust fan was used to evacuate the smoke and a supply fan was used to supply fresh air. The results of these two simulations were compared with each other. The fire power was 4 MW. The results showed that in the first scenario, the smoke concentration is 0.003 mol / mol and the temperature is 80 ° C. In the second scenario, the smoke concentration is 0.0002 mol / mol, which is 93% better than the first scenario. The temperature also dropped to 28 ° C by evaporating the smoke in 1200 seconds. In fact, the temperature improved by 65% compared to the first scenario. Reducing the concentration of smoke and lowering the temperature make it easier for people to evacuate during a fire.

First of all, the process flow diagrams (PFD) and the current state of the heat exchangers network were studied. Then, the necessary data were analyzed, process heat exchangers and their characteristics were compiled and the physical properties of the streamlines at different temperatures were calculated. Then, the target network was distinguished and the network was modified and pinch analysis was performed using ASPEN HYSYS software and ASPEN ENERGY ANALAYZER software. Finally, different scenarios based on pinch analysis were compiled and feasibility, computational, process and operational analysis was performed. Finally, by calculating energy efficiency in each scenario, only one scenario was selected and introduced as the best scenario. According to the selected scenario, the E-1001exchanger, which uses low pressure steam to heat the incoming feed gas, is transferred to another location in order to not only reduce the steam consumption, but also reduce the unit's power consumption by reducing the air fan load. The profit from this scenario was approximately equal to 1.5 billion tomans per year. Manuscript profile -

The considered power plant (reference power plant) in this research has a 100 MW unit in full load mode. Cooling towers have a high cooling capacity, but their high-water consumption due to the use of evaporative cooling causes steam to escape from the opening of the tower and be expelled it into the atmosphere. Wet towers provide lower temperatures than dry towers and as a result higher efficiency, but they have high water consumption. In this research, the environmental parameters affecting the compensatory water consumption required by the hybrid cooling towers (wet-dry) are investigated. Using cycle tempo software, simulation has been done to evaluate the performance of hybrid cooling towers in environmental conditions. The comparison of the volume of compensating water in the same cooling cycle, where only the hybrid cooling tower was replaced by the cooling tower, showed that it is possible to reduce the water consumption in the cooling process by 20% by using the hybrid cooling tower. Also, the use of hybrid tower cooling means that the increase in ambient temperature up to 30 degrees does not affect the amount of electricity produced by the power plant, and the amount of electricity produced in the power plant does not change with the increase in air humidity.

For this purpose, the city of Tehran was chosen as the pilot project. In the input phase, PESTEL analysis was used for environmental scanning, and in the analysis phase, the global business model was used. For data analysis, 23 experts and Delphi method were used. After the theoretical saturation and confirmation (98%) of the experts, the questionnaire was distributed among them to measure the variables based on the degree of influence and effectiveness; then the data was entered into MicMac software and one 18x18 matrix was formed. The results showed that the matrix filling index is 96.197%, which indicates the high influence of the identified factors on each other. The variables were divided into 4 types based on the placement type; and the variables "Investment in sports", "Community income level", "Government financial aid" and "Education and promotion of sports culture"were the most influential in the studied system. Also, 6 variables "unemployment rate",distribution and distribution of sports spaces and venues","per capita and infrastructures","cultivation and heroism","interest and support of local communities" and "performance in international arenas" have more impact than effectiveness. And are the driving variables of the system. The "climate and geography" variable has the least role in direct and indirect effects.

Therefore, the map of user changes that is the result of the process of detecting changes can be made based on multivariate images of remote sensing. The purpose of this research is to classify the images of the Tajyar Dam in three years to find out the extent of change in land cover and land covered with vegetation. Remote sensing techniques are the best means for extracting land use maps. In this study land use changes in the Tajyar dam basin have been studied using the supervised classifications in Erdas software. The Tajyar Dam Basin with an area of 10898 ha is located in East Azarbaijan province and Sarab city. In the study area, two landslide satellite images from1996 and 2006 and 2015 were categorized. The results indicate that 2007 hectares of lands covered with vegetation have been reduced and added to dry lands. This change has been caused due to severe agricultural activities, plowing and unplanned grooves. The effect of cold air currents in the northwest of the country has caused the region to have a semi-arid climate of cold. Due to the aforementioned limitation and the state of consumption of agricultural products and the lack of attention to the ability of agricultural land, farming in areas that have no potential for doing this activity has reduced the quality of vegetation. The supervised classification in this method was carried out with an overall accuracy of 87%, which is acceptable at the level. Manuscript profile -

Meanwhile determine the amount of tunnel wall deformation prior to supportinstallation is of great importance. When a tunnel is excavated, there is a certain amount ofdeformation, usually 35-45 percent of the fnal tunnel wall deformation, before the support canbe installed. Determining this deformation can be done using either a) observed feld values, orb) numerically from 3D fnite-element models or symmetrical fnite-element models, or c) byuse of empirical relationships such as those proposed by Panet or Vlachopoulos-Diederichs. Inthis paper, convergence-confnement method is applied to tracing ground characteristic curveusing numerical software models and then stress relaxation is exerted to modal that equivalentwith occurred critical convergence until prior to support installation. In this study, a new chartis introduced which unlike conventional charts, the modulus reduction flow has been used inthat vertical axis.

Mean MoreOne of modern world challenges is saving energy consumption. Multiple increase in energy price on one hand and limitation of fossil fuel as well as its consequent bio environmental pollution on the other hand have shown the necessity of sensible energy application. Meanwhile energy consumption in construction sector is so high that saving even as little as possible in this section will have significant effect on efficiency rate of no renewable sources. Considering multiple relevant parameters in energy consumption with no application of simulating tools cannot permit reasonable decisions on designing building parts. In this research the proportion of annual energy consumption of office building located in Semnan city climate with application of design builder software has been simulated. Accuracy of results from simulation has been validated with recorded numbers at annual electricity and gas bills at the building. Manuscript profile -

By simulation using quasi-static analysis, the effects of the geometric dimensions of the defect and different geometries of honeycomb cells on the energy absorption of the structure have been investigated. In the analysis, for each case three percent of defects, including 0, 10 and 30% were studied. The results show that the honeycomb structure with A-type cell geometry is completely destroyed, which can be due to the asymmetry of the structural cells. In the other two models, the structure retains its overall shape and by systematic modification of the cells, they have the ability to absorb energy during the collision. Also, the results show that the defects in these structures have a significant effect on their energy absorption capacity in which by increasing the defects, the energy absorption capacity decreases.

In this study, the tests were carried out with six different types of materials (Brass, Carbon Steel, Copper, Five layer and PVC). It was assumed that valve which causes water hammer was closed fast. Also, how valve closing, is another important issue for this phenomenon. The tests in two modes slow and fast closing valve results showed if it takes more time to close, water hammer is less and the waves would fade faster. Also by examining the results indicate that the diameter of the pipes increasing pipe's diameter, increases the mess flow and fluid's velocity therefore effect of water hammer increases. This phenomenon shows that effect of increasing fluid velocity is more powerful than increasing pipe diameter. Manuscript profile -

This study was conducted via qualitative approach using phenomenological method. Participants were selected by two methods of snowball and Criterion sampling to theoretical saturation boundary, 17 new teachers who were freshman at Farhangian University, in academic year 2012-2013. The participant who are new teachers in Mashhad were subjected to semi-structured interviews, in 2021. Transcribed interviews were analyzed via thematic coding. Lincoln and Guba criteria were also used to determine the reliability of the research. Findings revealed that there were 2 inclusive themes, 6 organizing themes and 14 basic themes, based on main challenges for doing an effective evaluation in primary schools by new teachers. Also main solutions for overcoming to these challenges can be categorize in 4 inclusive themes, 10 organizing themes and 27 basic themes. The results indicate that doing evaluation in Shad Software is one of the most difficult tasks carried out by new teachers. In a way that some of the evaluation challenges were so serious and new teachers didn’t have any idea or successful solutions, despite their best effort, to overcome them. But in the face of other challenges, by spending a lot of time and tolerating some work pressure, relatively they succeeded to perform a valid evaluation. Manuscript profile -

Looking at traditional cities and comparing them with modern urban planning, we see adverse environmental consequences in the scale of design of building units and the spatial structure of cities. Therefore, it seems necessary to identify the effective factors in the design of traditional sustainable cities, using simulation software before the project or in the proposed options, to the optimal forms in the components (individual buildings) and Urban combinations (urban textures) was achieved. The present research combines descriptive-analytical methods, typological studies, drawing and simulation of models, following the analysis of energy consumption and thermal comfort in different types of building forms, urban blocks, and spatial structure of Isfahan in 4 historical periods. Therefore, by using energy simulation software (Design Builder) and thermal comfort (Envi-Met) and analysis of Space Syntax, the relationship between independent variables (physical and spatial characteristics of the urban fabric) and dependent variables, the amount of energy consumption (to provide heating, cooling, and lighting) and thermal comfort, in each of the proposed scenarios, has been investigated. Based on the results, it is possible to formulate guidelines for the climatic design of urban structures in the form of three components; The system and pattern of segmentation and segregation of urban land, the shape and characteristics of the mass/space in urban contexts and the pattern of the network of texture passages, regulation, and operational construction. The dominant forms of the Qajar period are more sustainable forms than other historical periods in terms of energy performance and adaptation to the climate. Also, spatial structures with the highest degree of spatial connection can provide a higher percentage of thermal comfort conditions in urban open spaces. Manuscript profile -

The purpose of this research is to evaluate the urban development with satellite images between 1992 and 2016 and to evaluate its effect on the characteristics of hydrological drought events in the Samian area of Ardabil province. Land use change assessment shows that the agricultural and residential areas have been increased. Examination of the one-month SDI index in all stations shows an increase in droughts in different periods. The highest number of dry months is related to the last period (2017-2008) of Samian station for 80 months. The highest increase in the number of dry months is related to Gilande station, which has increased from 1 month in the first period to 66 months in the last period. The study of the quarterly SDI index in all stations except Atashghah station shows the increase of drought in different periods. The highest increase in the number of dry quarters is related to Gilande station, which has increased from zero in the first period to 36 in the last period. Despite the increase in rainfall during the period and the presence of wet climatic months, as well as the relative increase in temperature in the region and due to increased agricultural use and residential areas that have increased the harvest of surface water, the number of dry months in the region has increased.

In this study, land use changes in the past 20 years using the TerrSat software and its potential for prediction in the future were evaluated using the Markov chain of Ramhormoz. For this purpose, TM Landsat 5, OLI Landsat 8 was used for 1996 and 2016, along with topographic maps and area coverage. Images of both time periods were classified into four categories of land use: lands made by human hands, arable land, agricultural and uncultivated lands. According to the results, the lands made with 39.1% of the most positive changes and lands with vegetation cover with the rate of -29.1% have the most negative changes in the region and the trend of forest areas has been a downward one. Then, using the prediction model and classified images (1996-2016), the 2016 coverage map was predicted using the Earth-change model. After evaluating the model, the overall accuracy was 83.09 and the Kappa coefficient was shown to be 0.79, which indicates the high adaptation between the predicted map and the classified map. With the introduction of the land cover plan for 2016, the model for land-changeover, a 2025 land cover map was prepared.

When the dimensions of the components decrease, the sensitivity of the circuit increases and the quantum circuits become more vulnerable to the occurrence of defects and radiation in the environment. The two major gates in this technology are inverter and majority gates, and most circuits are built based on these two gates. This paper aimed to design a seven-input majority gate in quantum-dot cellular automata by imposing low overhead on the circuit. Using a majority gate with more inputs reduces cell count, latency, and complexity in the QCA circuit. However, perhaps the need to use the seven-input gate is not yet felt we then design and implement a number of logic circuits. A new 7-input majority gate is designed in this paper, with 19 cells. The proposed structure is single-layer with an occupied area of 24564 nm2 that produces the correct output in one clock phase, then a four-input AND gate, a four-input OR gate, a two-input XOR gate, a two-input XNOR, a three-input XOR gate and a full adder are implemented using the designed seven-input gate. Including all multi-bit full adders, using the proposed seven-input gate. The proposed full adder is designed by the seven-input majority gate proposed and a fault-tolerant three-input majority gate. Therefore, it can be said that the designed full adder is somewhat tolerable, that means, it is somewhat tolerable against the fault that occur in this technology. QCAPro software is used to analyze the energy consumption of the recommended structure. Then, the circuit performance is evaluated using QCADesigner 2.0.3 simulator software for quantum-dot cellular automata. Manuscript profile -

Also, new technologies such as the Internet of Things, artificial intelligence, self-driving cars, 5G, etc. will not reach their full potential unless an infrastructure communication network meets their needs. Security is critical to their infrastructure and services. On the other hand, the development of quantum computing technology in recent years and the construction of quantum computers with very high processing power and solving very complex problems faster than current computers has made cybersecurity, computer security and communication devices a vital and important issue for governments. However, with the advancement of quantum technology, these threats can be prevented by using quantum methods to distribute keys, so quantum cryptography is considered as an alternative to classical methods against quantum computers and cyberattacks. Quantum key distribution is the most popular sub-branch of quantum cryptography, and commercial examples are now available in the market. However, the implementation of quantum key distribution networks in fiber optics, which is discussed in this paper, is one of the solutions that provide unconditional security through quantum cryptography to establish secure communication. The distinguishing point of this article is to provide an overview of the latest research in the field of implementation of quantum key distribution networks in fiber optics. In addition, the quantum key distribution networks implemented in the world are reviewed and compared and the approach of different countries in this field is studied. Manuscript profile -

This cycle mainly causes disruptions to the programs' execution which may be undesirable. Disruptions could turn out to be more problematic in the web applications, because they usually have to provide round-the-clock services. Nowadays, there are systems called Dynamic Updating Systems which are able to update programs without disruption. However, a dynamic updating system capable of updating web applications is infrequent to date. The present study aims to propose approaches needed to compose a web-based dynamic updating system. Providing these approaches, we have focused on preserving programs' consistency. To this end, different states of a web application are considered, and actions which the dynamic updating system must perform in each state are described. This paper concludes with a discussion about the implementation and the evaluation of the proposed approaches. Manuscript profile -

The present study aimed to determine the structural break points in the Iranian tourism industry, using quarterly data from spring 2013 to summer 1399. All these tests have confirmed the existence of a structural break in the fall of 2019. However, if the coefficient decreases significantly, only the fall of 2019 would be recognized as a breakpoint in the Iranian economy. Due to the high volume of tourism and the growth of this sector in the spring and summer of 2019, it is expected that in the annual surveys, 2020 will be the only year that a structural break has occurred in tourism in Iran. Political events such as the Saudi Embassy or the referendum in Iraq Kurdistan, the signing of the UN Security Council, or the imposition of severe sanctions on Iran's economy have virtually failed to bring about structural changes in Iran's time series tourism models. There are more pervasive factors such as the Covid-19 epidemic that have caused a structural break in Iranian tourism. Manuscript profile -

The mechanism of these structures is such that the focus of energy dissipation is on the dampers, and the role of the concrete wall and tendons is to create stiffness and provide the self-centering capacity in the system resulted in the reduction of residual deformation in the system. The jointed self-centering concrete walls are a type of self-centering wall system where dampers are placed between two concrete wall panels. The most important point that should be considered in these structures is the optimal use of dampers in them. In the present research, a new system has been introduced, which is a combination of self-centering concrete walls with gravity columns. In such a way that the friction dampers were placed in the middle and side positions of the concrete wall. This research aimed to investigate the optimal numerical value for the "slip load of friction dampers" in the middle and side positions of the Self-centering concrete wall based on the "amount of prestressing force" in the friction screws of the dampers. In the current study, the resistance of damper materials, their shape and dimensional size are not considered as variable parameters and they are considered without influence in determining the optimal damping. In total, the optimal sliding load based on the prestressing force in the friction bolts has been simultaneously determined by two-way sensitivity analysis by OpenSEES software. Based on the results, applying the method of determining the percentage of the minimum response coefficient (R) based on parallel (two-way) sensitivity analysis can be recognized as a very efficient method for determining the most optimal friction damper in Self-centering jointed concrete wall systems. Furthermore, the prestressed and optimal force for the dampers indicated that the dampers located between the two walls (set of middle dampers) exhibit a specific optimal value and other dampers (set of side dampers) also present a different optimal value.

After numerical analysis of prestressed concrete beams with and without reinforcing fibers, their bearing capacity was investigated. After numerical analysis of prestressed concrete beams with and without reinforcing fibers, their bearing capacity was investigated. It was concluded that in the simple reinforced concrete and prestressed beams, cracks resulting from tensile damage in the middle cross section of the beams with maximum stress are continuously reduced with a gentle slope towards the supports. In simple reinforced concrete and prestressed beams, the highest stresses were created in the tensile reinforcements at the bottom of the beam and in shear reinforcements, the stress get started in the middle section of the beams and exhibited its maximum in the lower part of the beam section. In addition, in simple prestressed concrete beams, the capacity was increased by raising the number of prestressed tendons from 1 to 2 and 3. The capacity of beams with 3 tendons has increased by 79% and 22% compared to the beams with 1 and 2 tendons, respectively. The bearing capacity of prestressed concrete beams with C50 consumption category were increased by 6% and 5% contrasted to the prestressed concrete beams made of C30 and C40 concrete categories, respectively. By comparing the reinforced models using carbon reinforcement sheets in comparison with the glass type, the bearing capacity of beams containing carbon fibers are enhanced by about 12% (on average) compared to different types of glass fibers.

The basic idea of this system is to use the diagonal tensile field in which a steel sheet is created after buckling. A comprehensive research on irregularly patterned corrugated shear walls has not been performed so far. In this research, the study of this type of walls and also comparing their performance with flat and corrugated walls with a regular pattern is desired. The comprehensive studies have not been conducted to provide a more irregular and resistant pattern that can improve the seismic properties of regular patterns. This research aimed to present a new model of steel shear wall with irregular wave pattern that can present more buckling resistance than walls with regular wave and also has better performance in lateral control of the structure with ductility and better energy dissipation. For this purpose, the modeling results of finite element software using ABAQUS were compared with a valid laboratory results to verify its accuracy. There was an adequate convergence between the results, which indicates the correctness of the modeling. Then the models were created and dynamic analysis of time history in this software was performed on the models. Analysis of the models indicated that irregular waves can also behave well. In general, it was not possible to comment on the displacement, but there was a certainty about the base cut that the irregularity reduced the base cut to some extent, but still it was not possible to choose a suitable pattern for the irregularity.

Over the past years, researchers have proposed different systems for absorbing and dissipating earthquake energy in structures, which, in this regard, unrestrained buckling braces have been focused by engineers. The purpose of this research is to examine the behavior of short link beam in steel frames with buckling and non-buckling braces. For this purpose, three structures, 3, 6 and 9 stories with buckling and non-buckling braces are designed according to valid regulations and all seismic rules have also been controlled. Then, their lateral two-dimensional frame is modeled with eccentric braces on the SeismoStruct 2016 software. In order to investigate the behavior of the link beam, nonlinear static and time history analysis have been used for three far-field earthquakes and type 2 soil. In the following, the results of the shear force and the bending moment of the link beam and the nonlinear static analysis curves of the frames in two models with buckling and non-buckling braces are compared. The results of nonlinear static analysis show that the moment and shear in the non-buckling link beam can be up to 38 and 50 percent more than the frame with buckling braces, respectively. Non-linear time history analysis shows a higher growth of link beam forces in a frame with non-buckling braces than nonlinear static analysis. Manuscript profile -

Advances in engineering sciences and the utility of new materials have improved the quality of construction and industry. The utilization of materials such as FRP or prestressed and post-tensioned systems has been considered by many engineers due to researches performed and their proper performance during past earthquakes. In the present research, using ABAQUS software, the effect of flexural reinforcement of reinforced concrete beams using prestressed CFRP laminate (Carbon fiber reinforced polymers) has been investigated as a new and widely used method in strengthening and improving the performance of concrete beams. Different percentages of prestressing force according to the tensile capacity of CFRP laminate as an effective parameter in the final strength, have been investigated in this study. The results exhibit that the use of prestressing in CFRP laminate owing to its high tensile capacity and intrinsic performance can have a significant effect on increasing the stiffness and final strength of reinforced concrete beams. Analyses in this field indicate that the amount of prestressing force should not be more than 30% of the tensile strength of the- laminate, which is one of the cases mentioned by recent researches. Prestressing in the laminates also changes the cracking pattern in the critical area of the reinforced concrete beams. Manuscript profile -

With the advancement of technology and the presentation of new materials in the field of construction, the quality of retrofitting and improving of structures has also enhanced. Many structures in the world have been built using reinforced concrete materials, which have exhibited a good performance during previous earthquakes, too. The reinforcement of these structures and the presentation of new solutions to improve their performance have also been studied by many researchers and various solutions such as the use of concrete jackets have been proposed and applied. In the present study, using the posttensioned concrete, a new approach is presented to strengthen the flexural strength of reinforced concrete beams using ABAQUS software. In this method, by adding a posttensioned concrete layer to the reinforced concrete beam (base sample) from both sides, its flexural performance has been investigated. The results of the analyses indicate the appropriate behavioural compatibility of this method due to the high tensile capacity of steel cable, which can have a significant effect on ductility, improving performance, increasing the capacity of reinforced concrete beams and transferring of the plastic joint from the middle span to of the end of the beam.

Since MoreABSTRACT Steel Shear Walls are a lateral resistance system in frames that has attracted many researchers’ attention owing to advantages such as appropriate ductility, high stiffness, significant shear strength and energy absorption. Since the early 1980s, when key researches on unstiffened Steel Shear Wall (SPSW) were under considerations, researchers were continously trying to improve the performance and efficiency of this system. One of these efforts was the creation of the opening in infill plate. Studies on perforated-SPSW began in the early 1990s by the experiments of Sabouri and Roberts. Recently a perforated-SPSW which having some circular openings was presented and examined by the researchers of Buffalo University. In addition to a system for passing the utility through the infill plate, this kind of opening is useful when a required thinner plate is not available, so it can be possible to substitute a proper multi-perforated Steel Shear Wall with a solid plate. This paper presents results of a research on the effect of multi openings on the performance of SPSW. Beside the experimental investigation a numerical study was conducted using the well-known ABAQUS finite element program was conduvted. Eventually the results of numerical and experimental studies were compared with the Plastic analysis’ conclusion. Results show a good agreement between experimental and numerical hysteresis and envelop curves. Furthermore, the Plastic analysis reduction factors seem to be conservative. Manuscript profile -

Water-supply networks in the hydraulic systems for water transmission and distribution have always been considered by researchers. The hydraulic behavior of water transmission lines is based on speed, pressure and flow. The possible changes in the consumption pattern, population, network leak and diameter of pipe line as well as potential of pumps need to be reviewed. In this research, the evaluation of hydraulic management of urban water-supply networks was carried out using Water Gems software. This means that the diameter of pipe lines and the level (height numbers) are changed so that the pressure is reached to the standard level in the network. Additionally, with modeling this township in Water Gems network in addition to the management of pressure, other data including speed, flow and demand rate are also provided. The first mode is based on the true state of water and sewage network was modeled in Semnan province. The second mode network according to the first mode was modified by changing the diameter of the pipes used to supply standard pressure and negative pressures were destroyed. In the second case by changing the elevation of the standard pressure of the atmosphere was 5-7. The optimum diameter of 85 mm and 180 mm was determined. optimized elevation for reservoir is 1430 meters and by increasing, the low pressure or by reducing, the pressure level rises.

Economic studies of the road construction show that the road bridges allocate much cost to it and due to the delicate structures of their system; they have great vulnerability as well. Therefore the detailed design of the various components of the bridge should be considered further. Erosion and transport of bed material is separated from it by a process called scouring. Occurrence of scouring around the bridge piers is one of the main reasons for the defeat and destruction of bridges and their instability. So it is important to provide methods to control and reduce this phenomenon. In the present study, the modeling of non-submerged plate’s perpendicular to the water flow has been expressed in upstream of the cylindrical pier using software SSIIM.

Due to the fact that one of the most important reasons for the destruction of the bridges, especially in flood situations, is the local scouring around the bridge, the determination of the local scour depth near the bridges is very important. An important role in designing bridges is in the face of this destructive phenomenon. For this reason, it is important to provide methods to control and reduce this phenomenon. Using SSIIM software, which is a time-consuming three-dimensional software, scour and scrubbing are checked using collar and splitter. It was found that simultaneous use of collar and gap has a significant effect on reducing the scour depth and the results of numerical modeling show a difference of 20-25% with the results of the experimental model.

In order to be economical and reliable design, you have to get the maximum depth of deflection around the bases. Estimating the maximum depth of scouring with the purpose of determining the depth required for bridge bridges is necessary, as otherwise it may lead to bridge collapse. SSIIM software is used in this study, which takes into account the flow and sediment equations in a three-dimensional fashion. In this software, the flow field is obtained from the Navier-Stokes equations and the K-ε turbulence model, and then, using the nondetective solution of the deposit field and the continuity equation, the ground level changes are calculated around the bridge's base. Comparison of the results shows that the scour depth increases with increasing height, and if the angular gradient exceeds a limit, then the destruction of the wall of the scouring cavity is accompanied.

In order to have an economical and reliable design, the maximum scouring depth around the foundations must be achieved. Estimation of the maximum scour depth is necessary in order to determine the required depth for the bridge piers, because otherwise it may lead to the destruction of the bridge. In this research, SSIIM software has been used, which considers flow and sediment equations in three dimensions. In this software, the flow field is obtained from the Navier-Stokes equations and the εK-turbulence model, and then, using the non-permanent solution of the sediment field and the continuity equation, the floor level changes around the bridge pier are calculated. The results of this study show that the numerical model used, which is one of the three-dimensional models available to engineers, predicts acceptable values in flow simulation, calculation of free surface and calculation of bed topographic changes in the river. In some places the speed calculation error increases, but the model is able to model the distribution of velocity and rotational currents well. From the presented models, it was proved that under the same conditions, the scour around the square and cylindrical base is more than the rectangular base. Manuscript profile -

This kind has more effective length than usual sharp tip weirs. In this regard, they can pass more flow than usual weirs for channel with similar width and height. In this study, effective geometrical parameters on single cycle labyrinth weir flow coefficient are measured by means of FLUENT software in three-dimensional way. To model turmoil, k-Ɛ model RNG method and to position free surface profile, VOF method are used. The results of numerical models are compared with those of rectangular weirs with same width. The results for specific H/P show that vertex angle increases with flow coefficient increase and rectangular weir performance of same width is less than single cycle labyrinth weirs, since in same width channel the interference of abscission blades is more severe than single cycle labyrinth weir and such an interference in vertex causes the flow coefficient decrease comparing with single cycle labyrinth weir. Moreover, single cycle labyrinth weir in less hydraulic loads has appropriate performance and ascending trend of flow coefficient. Manuscript profile -

Considering the importance of earth slopes, the effect of static forces and earthquakes on its stability is extremely important. In this research, the optimization of the design of the Droodzen earth dam body is done by performing quasi-static and dynamic analyzes using Plaxis software. Based on the obtained results, geocell reinforcements increase the safety factor of dam stability and reduce the lateral deformation of the slope due to tensile strength and bending anchor. Also, by increasing the depth of the geocell placement, the tensile strength and bending moment of reinforcing increases, and by reducing the length of the geocell cover, the shear resistance of the top and bottom joint of the geocell decreases. Finally, we should mention that soil compaction leads to a significant increase in tensile force and bending moment along the length of the geocell layer. Manuscript profile -

Therefore Hydraulic performance of the emitter is an important factor affecting the capability of drip irrigation. Because of small size and complex structure of labyrinth-channel used in most drip emitters, it is not possible to observe the flow behavior of water passing through the channel. Also Process production of emitters is time-consuming and expensive. Therefore In this study, the flow in emitters' channels was simulated by FLOW3D software. For this purpose 3 types emitter (A, B and C) were selected and sizes of their channels were calculated by photographing with Scanning Electronic Microscope (SEM). To calculate the relationship between pressure and rate of emitters discharge, laminar model was used. Simulated results were compared with experimental results. Average of prediction error percentage (Er) was about 2 percent for A and B emitters and about 12 percent for C emitter. Hence simulated data showed a good agreement with the experimental data.

Little attention had been given to isolate the effect of the governance system on agricultural productivity which necessitate this research. This research is a global study on the relationship between regime type and agricultural productivity drawing data from three main sources. A total of 14 models and scenarios were estimated to isolate the continents and or regime types that could exacerbate or enhance global Total Factor Productivity (TFP). The results indicates that full democracy is practised in about 10% of the countries. TFP is highest in most countries that practice full democracy (FD) while it was lowest in countries under authoritarian regimes. From the results of the estimation of all the models, only agriculture contribution to GDP had about .45% impact on TFP over the period of this data. However, it would appear that changes to TFP is more likely to occur in countries within continents rather than in countries practising similar regime type. In terms of which regime or continent caused the greatest variability; Asia is on top of the continents while authoritarian regimes are on top of the regime type. The study recommends the institution of political reforms in countries operating imperfect democratic regimes to enhance investment in agricultural R&D especially in Africa, Asia and CIS. In addition, countries not practicing FD should work towards improving their TFP by at least 50% of the current level and translate the free resources to other sectors. Manuscript profile -

Methodology: This study is descriptive - analysis and scientomtrics indicators have been used. For data analysis with Lotka law, the number of productions of authors was calculated. Then, to ensure results and confirmed the results mentioned, LOTKA software was also imposed. In order to test data on Bradford's law, this law was also used. Findings: The results showed that the scientific production of authors in the field of geology during 1990 to 2010 is not confirmed by Lotka law and the law was not dominating in this study. While in reviewing of Bradford law, the results indicates that Bradford is confirmed for the scientific outputs of authors is in the period of study. Conclusion: The results showed that in the test Lotka law with scientific outputs of authors in the field of geology during 1990 to 2010, this law was not approved. It seems that with the changes in co-authorship of scientific outputs, this law is not dominant and requires further investigation, so as a general principle, at all times, be used. In reviewing Bradford law, the results show that this law has been confirmed in the scientific outputs of the authors in the field of geology in the period of study. whereas the authors are used as subjects of the articles. In other words, the greatest number of authors (as topics of articles) has produced the lowest number of scientific outputs that these documents are the core documents and by the greatest participation of authors have written.

Increasing environmental disasters has also concerned economists as well as environmental specialists, and has made the experts at management level to realise the need for protection and sustainable use of natural resources. In this study, it was tried to determine the economical value of Urmia Lake,usingLogit method which is based on people’s willingness to pay, by CVM method and WTP measurements. The main purpose of this study was to provide non-consumable value (conservation value) of this lake. In this method, 31 variables were investigated. The estimation of the model was carried out using the Logit method with EVIEWS software (10). Analyzing the results indicated that the amount of willingness to pay for each unit price rise is decreased by 21%. Finally, the average value of WTP for non-consumable economic value of UrmiaLake was estimated to be 52.58x103 and the total economic value of the lake was estimated to be $605 million.

In the present research, the nucleotide and protein sequence of enhancin and the phylogenetic relationships between them were investigated along with codon analysis of nucleotide sequences and motifs using computer databases. Materials & Methods: Sixty-seven nucleotide and amino acid sequences related to enhancin gene were extracted from GenBank and used to draw a phylogenetic tree based on the maximum likelihood method. Nucleotide sequences related to nine selected genes were selected and extracted from the Sequence Manipulation Suite database to check the frequency of codons. MOTIF Search site was used to find motifs in amino acid sequences. Results: The tree drawn based on nucleotide and amino acid sequences showed two and three main groups, respectively. The sequences of Agrotis segetum granulovirus, Operophtera brumata nucleopolyhedrovirus, and Choristoneura fumiferana multiple nucleopolyhedrovirus were each in their own separate group. In all nine selected nucleotide sequences, the most abundant codons included ATG and TGG that were associated with methionine and tryptophan, respectively. In the amino acid sequences, the conserved sequence HEXXH was identified. Unconserved sequences corresponding to HAISF, HCMAE, QTLGD, HQXXH and HVXXH were found in some sequences. Conclusion: Since the production and secretion of enhancin enzyme as much as possible can be used to increase the insecticidal activity of baculoviruses and be used commercially for pest control, bioinformatics studies to predict the nucleotide and amino acid characteristics of the mentioned proteins in this field, especially with the production of recombinant baculoviruses, can be helpful.

Partial rDNA sequence analysis is used to study the evolution and classification of living organisms. The study was conducted on 16S rDNA sequence of five native isolates of Bacillus thuringiensis using the polymerase chain reaction technique. Materials & Methods: Characteristics and phylogenetic relationships between five sequences of native isolates along with other isolates in the gene bank and other species of the genus Bacillus were performed with Mesquite software and leBIBIQBPP database. Results: The five native isolates were 92.06 to 99.93% similar to each other and 99.73% to 100% similar to other isolates of Bacillus thuringiensis. Phylogenetic trees showed Bt 1019, Bt 1020 and Bt 1039 in the first group and Bt 1001 and Bt 1091 in the second group. Based on Bt 1001 sequence analysis using leBIBIQBPP, the minimum distance with Bacillus frigoritolerans was obtained. The sequence of Bacillus anthracis was close to Bt 1019. The Bt 1020 sequence was closest to Bacillus cereus. In the case of Bt 1039, in addition to Bacillus cereus, the lowest distance was observed with Bacillus marcorinectum. The Bt 1091 sequence showed the most similarity with Bacillus frigoritolerans. Conclusion: Protein crystals were observed in the native bacteria. Toxic crystals are produced only by Bacillus thuringiensis. BLAST program for 16S rDNA gene sequence in the native isolates also showed the most similarity to Bacillus thuringiensis isolates in the gene bank. Moreover, the results predicted that the three native isolates Bt 1019, Bt 1020 and Bt 1039 could be toxic against lepidopteran pests and two isolates Bt 1001 and Bt 1091 could be toxic against coleopteran pests.

In such a way that organizations have requested to use consulting services in choosing the right software package; Because the wrong choice might lead to major financial losses. Indicators affecting the selection of accounting software should be considered before preparing the software. Facing with such an important decision, accountants, managers, and professional consultants all need indicators to rank these software packages to free them from subjective decision-making. The purpose of this article is to identify and explain the main factors that the organization should consider in its decision to choose the right software. Using Delphi method, the research questionnaire has been subjected to experts' opinions. These indicators are categorized in the form of two dimensions and ten components. These two dimensions are the features of the accounting software and the characteristics of the software vendor. The results of the research show that the three components of software reliability, technology and security from the aspect of accounting software features, as well as two components of software maintenance and upgrading, and the reputation of the software vendor from the aspect of the characteristics of the software vendor have the greatest impact on choosing the right software.

The method of the present study is causal-comparative and applied in terms of purpose. The statistical population of this study included preschool students in District five of Tehran in the year 1400. The statistical sample was recruited by non-probability method (available sampling). The individals were organized into two groups: a) those with experience in using computer educational software, and b) those without any experience in using computer educational software. The life skills questionnaire in children was utilized as the data collection instrument. The research data were analyzed using independent t-test by using SPSS version 22. The findings of this study showed that life skills among students with experience of using computer educational software were higher in comparison with students who had no experience of using computer educational software. It can be argued that computer educational software has a significant effect on life skills in preschool children. The results showed the effectiveness of computer educational software on life skills in preschool children, so schools and preschools can use appropriate educational software programs in order to enhance life skills among children.

Regarding ecological literature, studies on the diet of the genus Rana are rare; moreover, there is no study surveying other ecological and geographical aspects of this genus. Family Ranidae is represented in Iran by two genus and four species including, Rana ridibunda , Rana Camerani , Rana macrocnemis , Euphlyctis cyanophlyctis. No study has been conducted to survey the effective factors on the geographical distribution of these species. The aim of this study is to investigate the effective factors on the geographical distribution of these species. Sampling has been conducted from 19 provinces of Iran and four mentioned species have been caught. Ecological factors of every sampling location including, precipitation, temperature, vegetation, latitude, longitude, attitude are recorded. The relationship between ecological factors and occurrence of these four species has been analyzed employing SAM v4.0 (Pandlt;0.05). According to this study, the most relevant factors to the occurrence of the distribution of genus Rana are vegetation, latitude, and attitude. The most effective factors on the distribution of Rana macronemis are latitude, attitude, and vegetation. The most effective factors on the distribution of Rana camerani are attitude, vegetation, and latitude. The most effective factor on the distribution of Rana ridibunda is latitude. The most effective factors on the distribution of Rana (Euphylectis) cyanophlyctis are latitude, precipitation, and attitude. Manuscript profile -

The stress intensity factors are calculated for a finite plate containing two symmetrical hole-edge cracks. The problem is solved by two different methods, namely the finite element method and the FRANC software analysis. At first the finite element method is used and by writing a program in MATLAB software the stress intensity factors at the crack tips are calculated. The same problem is then reanalyzed with the Franc software and the results are compared. The effects of various factors such as the hole diameter, crack length and crack angle have been investigated on stress intensity factors. The results show that for small crack lengths, the effect of cracks length is more than that of the hole diameter on variation of normalized stress intensity factors, while it is the opposite for large crack lengths, the effect of hole diameter is more than that of the cracks length on variation of normalized stress intensity factors.

In this research, using the tolerance analysis capabilities in Inventor software to set the tolerance of the speed reducer gearbox. First, the dimensions of the conical rotor of the elevator gearbox were obtained by Geomagic reverse engineering software, and then the results were used in Inventor software to develop the gearbox model into a three-speed gearbox. Dimensional and geometric static tolerance analysis of this collection was done by using the worst-case, sum of square roots, process capability index and sigma methods. The results showed the worst-case method in tolerance analysis works more cautiously than other methods, as well as the residual sum of squares method, shows less laxity and interference than the worst-case method. Process index method, confirmed the assembly and in the sigma method, the sigma function considers the level of tolerance to be acceptable. Also, to ensure the correctness of the obtained tolerances, dynamic analysis has been done by using ADAMS software. The results showed that the set did not have any excessive slack or interference during movement. For validation, the results of this study were compared with Monte Carlo simulation results and showed good agreement. Manuscript profile -

Since almost all the organizations need to compete in different areas including services, giving a high quality service is so important to achieve a permanent competitive advantage. In order to survive in competitive markets, organizations and companies have to provide high quality customer services. The results of many researches illustrate that the service quality is the necessity for customer's satisfaction. Though, a lot of customer oriented companies have problem in recognizing and evaluating the customers' preferences and they often misunderstand the customers' demands. Because providing a high quality service requires understanding the relationship between the demands of customers and the quality of services provided by company. The organizations and companies which give software service also include this rule. The purpose of this research is to present a model to predict the customer's satisfaction from the provided services , also determine the influence of each effective variable on customer's satisfaction, as well be informed of customer's satisfaction level from provided service by the mentioned company. The proposed study used predictive algorithms such as Regression and Classification on data by Rapid Miner. Finally the method with the highest accuracy and minimum error were selected. In addition, in order to determine the most effective variables in customer's satisfaction, the weighting method was used. In order to make decisions and improve customer satisfaction, the results will be available for managers. Manuscript profile -

Russia's relations with Ukraine as a neighbor country in the region have embraced a painful separation and reflects the complex process of mutual identification in both countries. Hence, the Ukrainian crisis has always been responded to by Russian hardware power, the latest of which was the crisis in the Kerch Strait and the Sea of Azov, which has faced Russia's strict response to the Poroshenko’s sabotages. The present article seeks to answer the question of how Russia has managed the Ukrainian crisis and what techniques and tools have been used? The answer to this question is that the logic of the Russian approach to managing international crises suggests that, because of the importance of Ukraine for this country, Russia has managed the crisis in Ukraine in the form of crisis management models based on asymmetric, single line and single-multi-polar balance of powers, using hardware and software levers. The research methodology is based on a descriptive-analytical strategy. Manuscript profile -

Conseque MoreSoftware Defined Networking (SDN) is considered as an innovate architecture of computer networks by using the central controller. Any modification in network data and its arrangement can be effortlessly executed in software via the controller in these networks. Consequently, the identification and timely response to Distributed Denial of Service (DDoS) attacks can be achieved, which is not the case in conventional networks.This paper uses the α-Entropy statistical method considering a threshold and machine learning techniques, K-Nearest Neighbor (KNN), Random Forest (RF) and Support Vector Machine (SVM) to increase the accuracy of detecting DDoS attacks. In this method, the results are evaluated by 10-fold cross validation. The used dataset is ISOT, CTU-13 and UNB ISCX. The results of evaluation with a precision of 99.84% and FPR value of 0.10% indicate the high efficiency of the proposed model in SDN networks. Manuscript profile
