Following this, Cultural Revolution designers were adapted with new requirements of the community and orientations that introduced Revolution’s mottos after relative establishment of structure and educational contents of the universities. This matter, in conformity with general spirit of personality seeking processes of architecture, introduced necessity of changing in architecture training programs. In the field of architecture training, self-reversion , revival of past stable values, Permanent concepts are in history, structure and content of training program from the viewpoint of Cultural Revolution designers about importance of theoretical studies in training, joining of architecture training with precinct culture, historical examination of architecture before modernism, of national and zone perspective. Existence of word identity in the introduction of Cultural Revolution staff program in 1363 (1984), demonstrated attentions towards basics of new training program of architecture. Then, seeking identity in training process is followed by emphasizing on Islamic architectural history and Iranian architectural history. This period was contemporary with predominance of global process of postmodernism on West architecture. Postmodernism thoughts, criticizing inattention of modern architecture thinkers towards history of establishment of architecture in different places, chooses increasing, antonym, complex and metaphorical in its expressions. Prevalence of West postmodernism numerosity thoughts resulted in establishment of most of Iranian contemporary architecture works. On one hand, contemporary human’s social life, expansion of relationships and breaking boundaries are mixed with globalization idea. Contemporary world’s occurrences and mutations have widespread concepts in today life. Community technology, telecommunication, internet, satellite and so are things that involve human in network of relationships in different manners. So, after technical and technological advances of modernism, media could broadcast art and architecture mutations all around the world as other matters. Postmodernism attitude could increase its symbolic dimensions and attendance ways. Iran’s temporary architecture, which has a root in past architecture, is together with global widespread mutations, as a result of today world’s achievements and ideal that belongs to all of humans. Today architectures encounter with twosome status of doubt towards past values and captivation towards new values, as well as sentiment coherency to the past and excitement to the future; and this matter force them to search about recognition of personal and collective identity. Despite entering of current thoughts in West architecture to Iran, before entering and usage, tools and information technology was growing slowly and after the movement, it grows fast. It is necessary to evaluate reasons and results of these changes. While theoretical basics resulted from consideration of personality seeking, on one hand, and entrance of attitudes in West architecture on the other hand, (but without passing prerequisite processes that was caused appearance of the aforesaid thoughts), have significant influence on architecture of Iran. The present study involved in explaining Iran’s architecture approach after the Revolution and evaluating its personality seeking objectives against a phenomenon, called globalization, emersion of information technology, media and computers.

In this regard, the evaluation of dynamic changes in functional connectivity of the brain regions by using functional magnetic resonance imaging data has attracted their attention. In this paper, we focus on two model-based approaches, called the exponential weighted moving average model and the dynamic conditional correlation model, to estimate the dynamic correlation between the two brain regions. Initially, the performance of these two models is evaluated using two new simulations. According to the results, in these simulation studies, the dynamic conditional correlation model has better performance than the exponential weighted moving average model. Therefore, a dynamic conditional correlation model is used to estimate the dynamic functional connectivity of two brain regions (the anterior cingulate cortex and the posterior cingulate cortex) for three Iranian addicted to methamphetamine in a resting state functional magnetic resonance imaging. The dynamic conditional correlation model has a good performance in assessing the dynamic functional connectivity of these addicted to methamphetamine. In addition, the dynamic functional connectivity varies between subjects. Manuscript profile -

One of the most important generalizations of weighted composition operators, are generalized weighted composition operators which in special cases of their inducing functions give different types of well-known operators like: weighted composition operators, composition operators, multiplication operators and composition operators followed by differentiation operators. In this paper we study generalized weighted composition operators and give estimates for the essential norm of such operators on certain Banach spaces of analytic functions into weighted type spaces. The underlying Banach spaces of analytic functions include Bloch spaces, Zygmund spaces and weighted type spaces. Our estimates for the essential norms of generalized weighted composition operators imply necessary and sufficient conditions for the compactness of such operators. As another application of our results, we obtain essential norm estimates of certain well-known operators which are special cases of generalized weighted composition operators. Manuscript profile -

Properly efficient solutions are one of the most important theoretical and practical concepts that represent the behavior of the objective functions during a process change. Actually, these solutions are those efficient solutions that filter the anomalies of objective functions at some points, and this will help the manager to decision making to choose more important solutions. One of the most important tools for obtaining solutions with bounded trade-off in multi-objective optimization field is the Sum weighted scalarization method, which many authors have been studying it in interactive optimization field. This paper provides a method for obtaining properly efficient solutions near the ideal point with a theoretical and interactive view and using Sum weighted scalarization method. Since being near to ideal point will be abele to a preference of decision maker; this method examines the preferences of the decision maker without sacrifice the theory. Therefore, this paper presents an approach to finding properly efficient solutions near to the ideal point. Manuscript profile -

In the proposed method, after creating an expert team and determining their weights, the DMUs, inputs and outputs are determined and ranked in three stages. In the first stage, by using Euclidean Distance, the matrix of each expert is normalized and consequently, the DEA models corresponding to each expert are solved. The DMUs are divided into two groups, the first group consists of DMUs where at least one experts’ opinion is inefficient and the second group consists of DMUs where the views of all experts are efficient. In the second stage, the rank of the DMUs of the first group is determined by calculating the weighted arithmetic average. In the third stage, the rank of the DMUs of the second group is determined using the TOPSIS method for each expert, consequently, the final rank of the DMUs is calculated using the Weighted Borda Scoring Method. Then the proposed approach was implemented to rank the six-paths of the Blue Ocean Strategy of the IRAFA industry and management group. The IRAFA team of experts, consisting of seven senior experts, was formed, and their weights were determined. It was also found that six paths to restructure the Blue Ocean Strategy (DMUs) are effective on IRAFA Value Innovation, and the DEA model has four outputs (utility, price, cost, and acceptance). The results of solving the DEA model of each expert showed that there are four paths in the first group and two paths in the second group. Applying the Weighted Borda Scoring Method to rank the DMUs of the second group shows that creating a functional-emotional orientation for the organization's customers is the top priority of IRAFA Manuscript profile -

For each f∈H, we define a multiplication operator M_φ by M_φ (f)=φf. Let φ be an entire function. For each f belongs to the Fock space F^2, the composition operator C_φ is defined by C_φ (f)=f∘φ. For entire functions ψ, φ and f∈F^2, the weighted composition operator C_(ψ,φ) on F^2 are given by C_(ψ,φ) (f)=ψ.(f∘φ). Let T be a bounded operator on H, the set W(T)={⟨Tf,f⟩:‖f‖=1} is called the numerical range of T. In this paper, we find the point spectrum of some operators C_(ψ_1,φ_1 )+C_(ψ_2,φ_2 ), when φ_1 and φ_2 have the some fixed point. Moreover, we obtain an invariant subspace for the operator (C_(ψ_1,φ_1 )+C_(ψ_2,φ_2 ) )^*. Then by these results, for compact operators C_(ψ_1,φ_1 ) and C_(ψ_2,φ_2 ), we find the spectrum of C_(ψ_1,φ_1 )+C_(ψ_2,φ_2 ). Then for φ_1 and φ_2 which have the some fixed point, we investigate the numerical range of C_(ψ_1,φ_1 )+C_(ψ_2,φ_2 ). Manuscript profile -

In this paper, for a self map of the unit disk, φ and λ∈ℂ, we consider weighted composition operator, (λ𝐶φ)𝑓=λ𝑓𝑜φ , for every 𝑓 in Bloch space and Little Bloch space and inquiry the conditions under which the weighted composition operator 𝜆𝐶𝜑, is mean ergodic or uniformly mean ergodic on the Bloch and Little Bloch Space. In fact, we will show, if |λ|>1,𝜆𝐶𝜑, cannot be power bounded, mean ergodic or uniformly mean ergodic, in contrast, if |λ|<1, 𝜆𝐶𝜑, is always power bounded, mean ergodic or uniformly mean ergodic. In the case, |λ|=1, we will see that it depends directly to the Denjoy-Wolff point of 𝜑. Manuscript profile -

We study two special classes of these spaces of holomorphic functions on the upper half plane. Firstly, we prove these spaces of holomorphic functions on the upper half plane endowed with weighted norm supremum are Banach spaces. Then, we investigate these spaces of holomorphic functions on the upper half plane from a new aspect which has not been considered up to now. Indeed we prove that without any necessary condition on a weight such as restricting the rate of growth from below or above (constructing the upper bound or lower bound) or limit condition (except the continuity on the upper half plane) any weighted spaces of holomorphic functions on the upper half plane has a special subspace which can be written as countable intersection of closed sets.

In the last two decades, the great necessity for LST data in environmental studies and land resource management activities has made the measurement of LST as a major scientific debate. Discovering the spatial heterogeneity of land surface temperature and analyzing the key factors and specific effective spatial relationships that are affected by time series have great importance in land management. The aim of this study is to analysis of land surface temperature driving factors and spatial heterogeneity using spatial regression models. To review this issue, daily LST maps were prepared by the radiative transfer equation method using Landsat 7 and 8 data for 2002, 2013, and 2021 years in Bojnord city. The analysis of land surface temperature in areas where barren lands prevail requires nighttime temperature data. Therefore, MODIS night LSTs were also prepared as auxiliary maps. Pearson correlation, spatial autocorrelation, ordinary least square, and geographically weighted regression models were used for data analysis. Then, the performance of the models was compared using the coefficient of determination and the Akaike information criterion. The results showed that the GWR approach had a better prediction accuracy and a better ability to describe spatial non-stationarity than the OLS approach. The spatial response of LST and different influencing variables from 2002 to 2021 showed that the development of green space plays an important role in modulating land surface temperatures. Since LST is influenced by various variables, including topography, climatic and atmospheric variables, and vegetation, therefore, understanding spatial relationships and analyzing the areas with high LST can be useful as a way forward in the planning strategies.

Therefore, identifying landscape aesthetic beauty, and also fundamental planning and valuable areas, and proper planning and design in order to protect and promote the aesthetic value seem to be necessary and unavoidable. In this research, the aim is to investigate the performance of various experimental methods (multi-criteria evaluation using weighted linear combination), mathematical (logistic regression), and intelligent (neural network)) in estimating the suitability of the aesthetic value of Gorgan city. After theoretical studies and determination of effective criteria, mapping and standardization of the criteria were done and finally, the map of aesthetic-value suitability was prepared based on the methods of weighted linear combination, neural network, and logistic regression. In order to evaluate the performance of different methods and choose the optimal method, ground control points and ROC validation methods were used. The results showed that in the map resulting from the weighted linear combination method, a large part of the data was lost as a result of the linear combination of layers and weighting, and the neural network method with intelligent performance and the ability to combine and analyze non-linearly compared to the weighted linear combination method and also performing back and forth analysis compared to the logistic regression method, better separates the value of the studied area. According to the results of this research, it can be concluded that when there is little knowledge about the studied area and it is not possible to conduct field surveys to record valuable points of view, performing the weighted linear combination method can be a solution, but if it is possible to conduct field surveys to prepare a map of real educational samples as a dependent variable, more accurate results can be obtained with the help of the neural network method and logistic regression, more accurate results can be achieved, and in the meantime, the intelligent neural network method has a higher ability to distinguish the values of the environment image.

Since these activities are m MoreBackground and Aim: In recent years, some farmers in the plains of Saman in the province of Chaharmahal and Bakhtiari have changed the use of almond orchards in this area to agricultural land and pastures in order to provide food and fodder. Since these activities are mostly carried out without sufficient knowledge of the soil environment, there can be a serious threat to reduce soil quality. Therefore, studies on the effect of different managements on different soil characteristics and in the direction of a sustainable soil resource are very important. In this research, the effect of land use change in these areas on some physical and chemical indicators of soil quality was investigated.Methods:In order to investigate the effect of land use change on some physical and chemical indicators of the soil quality of three land use systems comprising a permanent almond orchard, permanent pasture and almond orchard converted to land were selected in the plain of Saman. 15 samples of soil (45 samples in total) were taken from 0 to 30 cm in the form of networks (30 x 30 meters) in each of the three land use systems considered. Some physical and chemical parameters of studied soil samples measured by standard methods.After collecting and saving data in Excel, a one-side analysis of variance (ANOVA) was performed on using the SPSS18 software and the comparison of the means was also carried out on the basis of the LSD test at a probability level of 1%.Results:The results of analysis of variance data showed that changing land use (changing of almond orchards to agricultural land) had significant effect on the indeces examined physical and chemical of at 0.01 level. The Land use change did not change the surface soil texture of the study areas. The soil texture of all three-study system was almost the same (clay loam inclined to sandy clay loam). According to the findings of the mean comparison, when almond orchards were converted to agricultural land, there was a significant reduction in total porosity, mean weighted diameter of soil aggregates (MWD), base infiltration rate, and soil organic carbon by 12%, 56%, 50%, and 54%, respectively. Conversely, there was a notable increase of 10%, 5%, 44%, and 18% in bulk density, pH, electrical conductivity, and soil lime percentage at a significance level of 0.01 (pr<0.01).In this study, substituting improved pasture plants with land grazed pasture significantly augmented the average of soil organic carbon, total porosity, solidity of soil aggregates (MWD) and base infiltration rate by 48%, 14%, 69%, and 40%, respectively, as compared to agricultural land at a significance level of 0.01 (pr<0.01). However, no significant difference was observed at a significance level of 0.01 (pr>0.01) between almond orchard and pasture land concerning the evaluated indicators.Conclusion:Overall, the parameters analyzed indicate that organic carbon, mean weighted diameter of soil aggregates (MWD), and bulk density are reliable indicators of soil quality in the study area. The average values of these indicators provide an optimal alternative for management and tillage practices in various land uses. Moreover, due to the delicate and vulnerable ecosystems of Saman Plain, it is recommended to avoid converting garden lands (such as almond orchards) into agricultural lands within the study area. This approach will help prevent soil erosion in one of the most sensitive areas of the country. Manuscript profile -

Howe MoreBackground and Purpose: Optimal and principled use of natural resources and land use management based on ecological potential, has an important role in environmental management and prevention of environmental degradation in the direction of sustainable development. However, ignoring the social need, despite considering the economic and especially the ecological potential in land use planning, leads to inconsistency with the terrestrial reality, which is one of the basic principles of any land use planning. Materials and Methods: In this study, using weighted linear combination method and hierarchical analysis and standardization of criteria using fuzzy sets, in addition to preparing an ecological and economic potential map for agricultural use, the social needs to change land from barren lands to agriculture were also mapped. By combining all of them, a map of the desirability of changing barren lands to agriculture in the Semnan watershed was obtained, which can also be used in modeling land use changes. Results: In this study, unemployment rate and population growth rate in the next ten years as the most important social factors of agricultural land use change, access to roads and electricity as the most important economic factors, and soil and water as the most important ecological resources of agricultural land use were determined. Discussion and conclusions: Considering the social needs and economic potential along with ecological capability, is more in line with the ground reality and can be used in the optimal allocation of agricultural land.

Since the aquifers are majority drinking water supply, the correct evaluations of these resources are necessary. Due to the uncertainty of water quality standard ranges, a method that leads to reliable results can be valuable. So in this study, two approaches as EWOV and SPA was proposed in order to groundwater quality assessment using fuzzy concepts and entropy theory. Method: For qualitative evaluation of groundwater resources, two proposed approach are considered. In the EWOV method based on Euclidean distance between each parameter and their standard, the quality ratings of each sample is determined using certain quality ranges. In the SPA method, the samples are evaluated based on fuzzy interval of each parameter. To evaluate the effectiveness of the two approaches, the 21 samples of SARAYAN plain were used. Findings: With implementation of the proposed approachs and extract the results of quality rankings samples can be found that the 42 percentage of the samples in wet period were in the mid-range class using EWOV method. By applying the uncertainty in quality classes, these percentages of monitored samples have acceptable quality level. Samples quality rankings study due to its location in the plains shows the results of SPA are more coordination with natural conditions of the aquifer. The results of the SPA method imply that the parts of the northwest, north and mid-plains are good and have acceptable quality for drinking consumption. Also, 42 and 74 percent of samples are located in quality classification of acceptable and acceptable to moderate in the wet and dry seasons, respectively. Discussion and Conclusion: Comparison of two methods result are indicative the appropriate precision of quality ranking offered by the SPA method and being consistent with the hydrogeological characteristics of the aquifer (such as P11 and P15). So, SPA as a preferred method in quality assessment of groundwater is recommended. Manuscript profile -

This type of behavior can be divided into two categories based on the different driving forces behind the analysts’ herding behavior.. For instance, if one analyst lacks the ability to research and provide recommendations, he or she may follow, or even copy, a famous analyst’s reports. Such action will result in herding behaviorIn this paper, we build undirected weighted networks to study herding behavior among analysts and to analyze the characteristics and the structure of these networks. We then construct a new indicator based on the average degree of nodes and the average weighted clustering coefficient to research the various types of herding behavior. Our findings suggest that every industry has, to a certain degree, herding behavior among analysts. Furthermore, we relate the two types of herding behavior to stock price and find that uninformed herding behavior has a positive effect on market prices, whereas informed herding behavior has a negative effect.

The tubers are the main means of propagation and distribution of Purple nutsedge. Information on environmental conditions that regulate the growth of the vegetative organs would help to predict the emergence time of perennial weeds. Several methods of germination were tested to compare the germination potential and determine the thresholds (the main temperatures) for germination of the tubers. The results showed that the () and ( methods are not an appropriate index for estimating the temperature thresholds and evaluating sprouting potential. Based on germination rate (tubers per day -1) and weighted germination rate (tubers per day-1) indices, temperatures of 25 and 30°C were the best temperatures. On the other hand, based on the thermal germination rate index, (tuber per°C -1 per day-1) the best temperature is 25°C. Among indices, the thermal germination rate index is a more justified assessment for precise description of sprouting potential versus temperature due to take into account the amount of used heat. In order to study the germination percentage, germination rate, weighted germination rate, Dent-like model showed better fit (R2 adjusted =0.83 to 0.99) but for study of the thermal germination rate index segmented model was superior model (R2 adjusted =0.76). In general, the minimum, optimal and maximum range of germination of Purple nutsedg was determined to be between 7.51 to 9.20, 28.5 to 32.62, and 0.43 to 42.49 ° C, respectively. Manuscript profile -

The ecological criteria such as soil, climate, water resources, geology and physiographic, as well as socioeconomic criteria, such as land use, distance from road, distance from built-up areas, distance from sightseeing attractions, and distance from tourism facilities were identified and then quantified using fuzzy method. In order to generate a land use map, remotely sensed data of OLI land sat 8 dated was used. Field data were collected in 2015. Thereafter, the factors influencing the allocation of lands to ecotourism were ranked using analytical network process method. Finally, using a weighted linear combination (WLC) operator, all information layers were combined in a ArcGIS®10.1 environment, followed by preparation of the final map of the ecotourism development power. In order to carry out the accuracy assessment, 20% of homogeneous land units which were suitable for ecotourism were randomly selected. The result of field check proved that 94% of the identified land units were completely compatible with natural condition. The obtained results indicate that the ecological criteria account for 0.64 of the final weight in total, suggesting the greater involvement of ecological criteria in developing functionality for ecotourism. The results from the quantitative method (WLC) showed that 75.2% of the study area are capable for ecotourism purposes, although the degree of culpability is varied. The rest (24.8%) has no suitability for ecotourism. From the capable areas, about 30.32% are highly capable for different ecotourism purposes. Concomitant use of fuzzy logic and ANP method for prioritization of criteria provides a more logical and flexible condition for land evaluation based on WLC method. Manuscript profile -

Therefore, for the optimal management of the natural areas, awareness of the land use ratio is a necessity. Soil erosion is one of the environmental disasters that annihilates thousands of soil, crops each year, and land use change is one of the important factors in erosion. Therefore, the present study was conducted to investigate the land use change trend in Nair, Ardabil province, and its effect on erosion using GIS and RS in order to carry out the research, images from 2000 and 2016, OLI and TIRS sensors, Landsat 8 were used and land use map was prepared using a controlled classification method. The erosion zonation map was performed using landuse maps and factors such as slope, lithology, distance from the road, distance from the waterway, precipitation and soil using Critical Weighing and Weighted Linear Combination (WLC). The results showed that the highest amount of area in 2000 was related to dry land farming with 442.38 km2 and semi-condensing pastures with an area of 347.39 km2. In 2016, the highest area of use of rangelands density, and then the use of semi-metamorphic rangelands are 478.76 and 458.5 km2, respectively. According to the erosion zoning plan of 2000, 17.25% and 25.55%, respectively, according to the 2016 erosion zonation, 12.44% and 26.51% of the city area are located in two high risk and high risk categories.

This study has identified and prioritized the potential of ecotourism sites in the Kojur basin of Mazandaran province. Physiographies criteria, including slope, direction, and elevation, as well as criteria of distance from road, river, village, sliding locations and canopy percent, were selected as the appropriate index. The criteria were evaluated and fuzzy by the experts and Analytic hierarchy process (AHP) method. Subsequently, using the Ordered weighted average (OWA) scenarios, the appropriate ecotourism site was selected. To reduce risk and increase managerial power, Boolean logic was used. The results showed that the landslide and the roads had a maximum value of 0.315 and 0.238, respectively. The output maps of the OWA scenarios have shown that the northeastern range of the cougar basin is the most optimal location for the establishment of the ecotourism site, and the northern region was ranked next. In the scenario of the low-risk level and non-compensated, and low-risk level and low compensation scenario, 83 hectares of land were recognized for the appropriate ecotourism site. While, average risk and complete compensation, high risk and low compensation, average risk and non-compensation and high risk and no compensation, were 3179, 1255, 1909, and 2577 hectares respectively for ecotourism sites. The Boolean logic output showed that about 47 hectares of northeastern lands of Kojour basin are an appropriate ecotourism site. Manuscript profile -

However, the low spatial resolution of these datasets has limited their application in localized regions and watersheds. So, having an accurate estimation of precipitation by satellites along with the adequate spatial scale in hydrologic studies is the main goal of this study. In this research, Geographically weighted regression (GWR) method was investigated to downscale the Tropical Rainfall Measuring Mission (TRMM-3B42 Version 7) over the DEZ river basin in the southwest of IRAN for 2010-2011. Downscaling was performed based on the non-stationary relationships between the TRMM precipitation and the Digital elevation model (DEM) derived products, the Normalized difference vegetation index (NDVI), the Enhanced vegetation index (EVI) and the Land surface temperature (LST). The result shows that the downscale precipitation at 1 km spatial scale had significantly improved spatial resolution, and agreed well with data from the rain gauge stations. For the 16-day precipitation, Mean square root means square error (RMSE) and absolute mean error (MAE) values are 22.7 mm and 7.45 mm, respectively. However, the accuracy of the model varies in a different location and depends on the vegetation condition. Manuscript profile -

Sound Speed was calculated using Chen-Millero formula and pressure, salinity, and temperature data. The data extracted from World Ocean Atlas 2013 with regular mesh grid 0.25 degree. Sound speed was calculated using the Chen-Millero formula. Spatial analysis of the sound speed comparison based on three methods Kriging, Co-Kriging and Inverse Distance Weighted. These methods were performed using GS+ software in both warm and cold season. The best method finally used to forcast and prepare the plans of zoning sound speed. The Pearson’s correlation test was performed between independent variables and sound speed showed that the maximum correlation occurs between temperature and sound speed. Therefore, the temperature was considered as the auxiliary variable in Co-Kriging method for spatial analysis of sound speed. Cross-validation results showed that model's forecasting in cold season was better compared to warm season in this region. Results of spatial analysis showed that the sound speed decreased about 20m/s in all layers from the Hormuz Strait toward the northwestern part of the Persian Gulf. Because of the increased salinity the maximum of sound speed was always in the south shallow area. In all investigated stations, sound speed reduced with increasing depth, due to temperature reduction and the sound channel is not also observed. Manuscript profile -

But the wide variety of options and parameters, variables uncertainty and long terms in environmental planning, causes the decision-making becomes more complex. So multi-criteria decision-making methods can meet these challenges. Thus the aim of this study is to identify suitable areas for eco-tourism in Kiamaky wildlife refuge using MCDM method Based on fuzzy logic in GIS. According to the effective criteria on the eco-tourism in this area; obtained from previous research and expert opinions, 15 criteria maps (climate, lithology, height from sea level, slope, aspect, land use and distance maps from residential area, road, river, police station, environmental guard station, sensitive habitats, shrine, spring and waterfall) are produced and classified as input. To determine the weights of criteria, opinions of experts in the form of Delphi Method were applied. The criteria matrix formed and the relative importance of all criteria was defined using the AHP method and pairwise comparison. Finally eco-tourism appropriate priority map was produced using Weighted Linear Combination (WLC) method and applying the index of the importance of each criterion to corresponding classified map. According to mentioned map, 15% and 34% of the area eligible for perfect and good for eco-tourism respectively, and 4% of the area are medium for this purpose. In this study, besides confirming previous studies, power and usefulness of GIS in locating and combining different ecological criteria were shown. Manuscript profile -

The gool of this work is to evaluate the energy consumption in the Kohgiluyeh and Boyerahamd province industry considering the industries with 10 and more employees. As in the calculating of the energy efficiency, several outputs and inputs must be considered in form of the productiion function theory, the data envelopment analysis is used to calculate the energy efficiency in the industrial units. Then the results of the energy efficiency, existing barriers and the practical consideration will be explaiend. The results of the efficiency model show that the most important factor of the inefficiency of the province's industry is the large population of job seekers and is the lack of optimal utilization of the workforce in the province's industry.

Studies have introduced excessive depletion of aquitards as the dominant factor in the occurrence of this hazard. In this study, the main aim was to take the impact of other spatial factors involving land subsidence into consideration. To devise a plan whether to pause or reduce the subsidence rate, we need to understand the mechanism of each factor inducing land subsidence. Here, we show the outcomes of a Geographically Weighted Regression (GWR) method with a fixed Gaussian kernel to identify the impact of each of the spatial factors inducing subsidence compared with the results from a Multi Linear Regression (MLR). In this regard, outputs of a compiled Interferometric Synthetic Aperture Radar (InSAR) time series analysis of the 15 Envisat ASAR images consumed to capture displacement from 2003 to 2005. Afterward, a kriging interpolation method is implemented to generate a surface of subsidence. The Python package "mgwr" is used to compile both GWR and MLR models. Several statistical diagnostics are performed to assert the GWR superiority over other non-geographical methods when dealing with spatial data. Finally, the GWR results show that just six factors out of 10 tend to be the dominant factors Manuscript profile -

Remote sensing is one of the data collection methods in which it has the least amount of direct contact with the objects and features being measured and unlike other methods in which human factors play a role in collecting and interpreting terrestrial data, in remote sensing method the task of collecting information will be the responsibility of the sensors. Due to the over-exploitation of natural resources, the landscape is constantly changing and monitoring these changes as well as updating maps is costly and time consuming, so many developed countries now have to prepare maps in Different levels use satellite data. The factors studied in this research include 1 preparation of land cover maps and land use of a part of Khuzestan lands. 2 Evaluation of bio-ecological potential in agricultural development of the study area by weighted overlap method. With regard to collecting information, studying the obtained maps and calculations, determining the criteria, final weights and classification of layers in determining the potential of the region for agricultural use, the amount of changes in agricultural areas between 2014 and 2016 was determined. According to calculations, it is about twelve percent, which according to the changes that have taken place are very significant and show the intensity of the changes in recent years. Loss of vegetation is a factor in increasing wind speed and destroying soil texture and structure. It is also a cause of dust, the result of which can be seen in recent years. Manuscript profile -

There are two major approaches MoreHyperspectral imaging concerns measurement and interpretation of spectral imagery acquired by satellite, airborne, terrestrial, or laboratory sensors over visible, infrared and sometime thermal spectral regions of electromagnetic spectrum. There are two major approaches for classification of hyperspectral images: the spectral or pixel-based techniques, and the spectral-spatial or object-based techniques. Recently, an effective approach for spectral-spatial classification has been proposed using Hierarchical SEGmentation (HSEG) grown form automatically selected markers. This paper aims at improving this approach for classification of hyperspectral images in urban areas. The Weighted Genetic (WG) algorithm is first used to obtain the subspace of hyperspectral data. The obtained features are then fed into the marker-based HSEG algorithm. Then, the contextual features from segmented images are extracted. For spatial features, area, entropy, shape, adjacency and relation features are considered as the potential components in feature space. Finally, using both spectral and spatial features, the image objects are classified by a rule-based classifier. The experimental tests are applied to two datasets: the Berlin, and Quebec City, which are two known and benchmark datasets in hyperspectral imagery. The evaluation of results showed that the proposed approach achieves approximately 16% and 9% better overall accuracy than the Original-HSEG algorithm for these datasets respectively.

Generally, oil spill is one of the main pollutions in this region. Determining the degree of sensitivity of coastal areas to this type of pollution is the first step to control and prevent oil pollution. The aim of this research is to predict the vulnerability of oil spill in the Persian Gulf. Therefore, in this research the criteria of oil pipelines, oil platforms, shipping lanes, ports, heavy metals, water level fluctuations, rainfall, sea currents, air pollution and monsoons were used to determine the high-risk areas vulnerable to oil in the Persian Gulf. The innovation of the current research is to provide a new hybrid approach to determine the effective vulnerability criteria of the Persian Gulf. In this regard, the combination of geographic weighted regression (Gaussian and triple cubic kernels) and particle swarm optimization algorithm were used. The proposed hybrid method is suitable for spatial regression problems because it is compatible with two unique properties of spatial data, namely spatial autocorrelation and spatial non-stationary. The values of R2 and RMSE obtained from the GWR method with the triple cube kernel were 0.9971 and 0.2142, respectively, which indicates the high consistency of the triple cube kernel compared to the Gaussian kernel. Also, the obtained results showed that oil transfer pipes, oil platforms and the passage of oil tankers have a significant impact on the vulnerability of the Persian Gulf. Manuscript profile -

Therefore, each result for one of these types of fuzzy sets can be directly rewritten for each (isomorphic) type of fuzzy sets. In this paper, we show that there is a strong connection between weighted graphs and fuzzy graphs. We accomplish this by using lattice isomorphisms. Consequently, under certain conditions, results for one area can be carried over immediately to the other. Many situations in fuzzy graph theory do not depend on the weights of the vertices. The situation of providing weights for the vertices of a weighted graph is also considered. We also consider lattice homomorphisms with an illustration involving nonstandard analysis. In particular, we consider a nonstandard weighted graph, i.e., a graph where the weights of the edges are from a nonstandard interval. Manuscript profile -

Viability of villages is affected by elements of time and space. Rural settlements vary according to the time period and geographical location. This study aimed to evaluate the relationship between the viability and facilities and utilities. The method of the study according to the nature of the study was analytical and as far as the purpose of the study was considered, it was practical. The necessary data were gathered from libraries, questionnaires and interviews with the people and local authorities. The study population consisted of 20 villages of rural households in Daman, Iranshahr consisting of 17 villages respectively. The sample of the study consisted of 287 people and 17 villages. In order to rank the villages regarding the facilities and services of center-weighted index model and also for ranking those villages based on the status of environmental indicators the VIKOR model was used. The evaluation of the obtained results showed that there is no significant correlation between having higher levels of service receiving and viability. Populated villages were shown to benefit from a higher level of services and facilities according to the results of center weighted model, but were at a low level of viability in the environment according to VIKOR. As a result, it cannot be said that only by providing the villages with equipments and facilities, the villages can be compatible and healthy. On the contrary, the results are in contrast with the positivists’ comments who believe that by increasing the level of services, environmental and biological abnormalities and problems will be removed in villages.

Energy intensity reduction in electrical devices and enhancement of their efficiency and performance, electricity loss reduction and voltage profile improvement of the power grid are some instances of optimization usage in power systems. Refrigerated systems, such as refrigerators, can, in addition to exploiting PV systems in a power grid, be part of the supply and demand of electrical energy, so that they store energy as energy and, in the necessary conditions, allow Energy to injecting into the power grid by a photovoltaic system. In this paper, the design and construction of a photovoltaic refrigeration system connected to the network and its optimal performance is discussed. The objective cost and refrigerating temperature functions are considered as two main goals and the final answer is chosen by using the non-dominated sorting genetic optimization algorithm and then using the weighted sum model method. The simulation results with MATLAB software as well as the results of implementing the proposed system's hardware system in the project verify both the performance and the optimal performance of the proposed system.

Urban sprawl in Tehran has led to several challenges in achieving sustainable development. A spatial analysis on urban sprawl in traffic area zones (TAZ) of Tehran has been investigated for the past two decades (2001-2020) using the Weighted Urban Proliferation (WUP) method. Then, the minimum access distance between each pair of TAZ-hospital has been calculated using Network Analysis and the relation between sprawl determinants and accessibility has been investigated. Finally, the Lorenz curves and Gini coefficients have been calculated. Results show that the sprawl level has decreased significantly in Tehran over the past two decades. Consequently, because of the direct relationship between dispersion and access distance, the maximum distance to the nearest hospitals has been reduced about 3 kilometers. However, the calculated Gini coefficients show a 10% growth over the study period; in a way that, in 2001, 90% of hospital opportunities were distributed among 29% of population, while in 2020 the same share of opportunities are distributed among only 7% of population. Results indicate that urban sprawl reduction can only increase accessibility standards and promoting equity of accessibility requires proper attention and management of socio-economic variables along with urban sprawl.

As experts have tried to focus on the context and surroundings proximity, neighborhood, compatibility and incompatibilities, utility and other factors. By the expansion of geographical information systems, it is possible to focus on these factors and their impact on the planning process for land use allocation. At the same time, many scientific efforts have been made to integrate these systems and multi-criteria decision-making methods in order to enhance their ability to support decision making. Methods used in this field have also been widely used in various studies; one of the most important applications of these methods in urban planning is to determine the suitability of each parcel for allocating urban land uses. In this article which is applied in terms of purpose and is descriptive analytical in terms of method, the land-use suitability analysis as a scientific technique along with linear combination, and Delphi methods, have been used. Findings, which have been obtained from overlaying analytical maps (land prices, access to communication axes, number of blocks of land and air pollution's maps), indicate that what type of land use is more suitable for each parcel. The results of this paper are presented in the form of land use allocation scenarios. Comparison of the results of modeling with current situation shows that out of 2,166 parcels in the study area, 521 have no suitable uses and need change. Manuscript profile -

In this regard, the Tehran Stock Exchange (TEPIX) index was used as a representative of market portfolios and daily data for the period 13/10/2009-12/11/2019. In this study, first, the results of estimating the value at risk using two models of exponentially weighted Moving Average (EWMA) and Monte Carlo simulation (MC) are presented. The performance tests of these models are then compared with other models including GARCH and historical simulation models. The estimation results of these models were obtained using Eviews 10 and Matlab 2018 software. The results show that the exponential moving average (EWMA) model is more efficient and more accurate than other models. The results also show that based on violation ratio and Back Tests, non-parametric models such as Monte Carlo simulation have overestimated the value at risk . Manuscript profile -

Market power specifies how firms in a market influence prices, and reveals the level of competition in the market. Hence, the main aim of this paper is to investigate the impact of market power and macroeconomic variables effects on banking deposits in Iranian deposit money market using dynamic Bresnahan-Lau’s and weighted average least square approach for the 18 bank in the Iran industrial banking sector. Annual data for the period of 2008-2017 has been collected from annual financial statements of Iranian banks, Statistical Centre of Iran, Monetary and Banking Research Institute of Iran and central bank of Iran. The main empirical results indicated that the nominal exchange rate and liquidity money have negative and other extracted macroeconomics variables have positive and significant effects on the deposits of banking sector during the period of study. Moreover, the Dumitrescu-Hurlin panel Granger Causality tests confirmed the unilateral causality from macroeconomics variables and market power to the bank's deposits. Manuscript profile -

In this study, data of 183 companies listed on the Tehran Stock Exchange were collected. To collect information and data, the library method was used and in order to investigate the relationships between variables and test the hypotheses, the multiple regression model in Eviews software version 10 was used. The main hypotheses of this research are based on the fact that in order to make management decisions about the optimal capital structure of the company, we can act based on the model of market timing theory and revised theory of pecking order. In the results of this study, the companies in order to finance themselves, in fact, follow the theory of pecking order and market timing. The research findings show a non-linear ᴜ shape relationship between debt and deficit changes and a direct linear relationship between capital and deficit changes. Also, testing the model related to market timing shows a positive and significant relationship between the weighted average of external financing and capital structure. Manuscript profile -

The results of this study show that the price variables of cryptocurrencies with different creation mechanisms from Bitcoin and also the number of circulating cryptocurrencies with similar mechanism to Bitcoin and the volume of liquidity of US dollars affect the price of Bitcoin. On the other hand, the Forex market currency pairs, such as the dollar to Canadian dollar, the dollar to Australian dollar and the dollar to New Zealand dollar, which are less valuable than other major currency pairs in the Forex market, affect the price of Bitcoin. Also, the variables in the number of bitcoins, the number of cryptocurrencies in circulation with a different mechanism from bitcoin, the global price of gold and the number of searches for the word bitcoin in Google on its price have low coefficients. Overall, the results of the two methods of Bayesian averaging and Weighted Averaging Least Square are largely the same, and the use of the optimal pattern selection method confirms this.

Value at risk actually summarizes the types of risks in a single digit, and it releases the senior management from bunches of risk calculations. The purpose is to design a model which provide an optimal combination for holding 6 currency reserves such as U.S. dollar, Dirham, Yen, Lira, Won, and Euro in Bank Mellat using the reference rates data of the aforementioned currencies in 2018. At the end, the model was solved using LINGO and Excel software. The results show that the maximum share of the US dollar and the dirhams in the currency basket of Bank Mellat are 33% and 67%, respectively. Accordingly, if the share of that currencies mentioned above exceed the obtained digits in the currency basket, then the maximum expected losses on the currency portfolio increase over the time and at the level of desired level of confidence. Also, other currencies are so risky, therefore Mellat Bank, to hold these currencies must plan more based on its trading needs. Manuscript profile -

Accordingly, identifying the capabilities of the land before loading various activities is very important. Otherwise, many of the investments will be wasted. As a result, assessing the land use potential for planting different crops is the first strategic priority for increasing production and optimizing resource consumption. In order to study the role of physiographic factors in the ecological capability of Golestan province for the planting of peas, geographic information system and weighted linear combination method were used. Agricultural needs and geological variables including soil texture, elevation, slope and aspect are determined from the available scientific resources, grading and required maps were prepared. For data standardization, fuzzy logic was used and we used the analytic hierarchy process (AHP) method to weigh the criteria. Finally, using the weighted linear combination (WLC) method in the TerrSet software environment, a potential mapping plan for peas was prepared. The results of the weighting of the criteria with the AHP method showed that the slope with the maximum of 0.2790 and the elevation had the lowest coefficients of 0.1038. Also, the results showed that a large part of the agricultural lands located in the province center (70.51%) has suitable conditions for the planting of peas and 6.08% of the total area of land is less suitable and 7.2% is half suitable, which includes lands Located in the mountainous and highlands of the province.

Authors usually suppose that weights are given in advance, and focus on the solution methods for the specific problem at hand. However, weights directly settle the class of optimal solutions, and are of utmost importance in any practical scheduling problem. In this study, we propose a new weighting approach for single machine scheduling problems. First, factor weights to be used in customer evaluation are found by solving a nonlinear optimization problem using the covariance matrix adaptation evolutionary strategy (CMAES) under fuzzy environment that takes a pairwise comparison matrix as input. Next, customers are sorted using the technique for order of preference by similarity to ideal solution (TOPSIS) by means of which job weights are obtained. Finally, taking these weights as an input, a total weighted tardiness minimization problem is solved by using mixed-integer linear programming to find the best job sequence. This combined methodology may help companies make robust schedules not based purely on subjective judgment, find the best compromise between customer satisfaction and business needs, and thereby ensure profitability in the long run.
