In finance field, two ways are the most important to analysis, fundamental and technical analysis. Different experience showed that, using one of them, independently, cannot bring in return more than they are used together. So, it seems are needed more researches in this section of finance field. In technical analysis by using information such as prices and traded volume, indicators are calculated and base on roles that introduce with them, decision are made. It probably the normal roles of indicators are not profitable more than before and are not able to bring extreme return to investors that use them. In stock market without enough efficiency, using technical analysis caused returns more than using fundamental analysis, independently. In this paper will tested to optimize indicators’ normal roles and is tried to produce efficient tools to bring return more. So that are used 50 companies that are much traded in years between 21 of march 2008 to 20 of march 2012 and optimizing are done first by using trying all of area and in second step by using enetic algorithm and finally compare to result from normal roles of indicators and buy and hold.

Background and Objective The protection of natural resources, especially land, and their use, has long been considered. It can be said that because land use has undergone many changes over time, these changes have direct and many effects on the ecosystem and the environment and consequently have various consequences, including these consequences that can be used to change land use. The area was affected by the rapid expansion of urbanization and its effects on land-use patterns in the surrounding environment and, finally, land fragmentation in these areas. Accordingly, in many cases, converting land use from its natural state to artificial land use has irreversible consequences. To reduce the consequences, this can be adapted to the land use structure. Land appropriateness refers to matching the capacities of a plot of land and its land use, and the disproportionate allocation of land use and disregard for its changes has many consequences such as socio-economic segregation, environmental depletion, and loss of resources. Decisions in land and resource management should always be guided in a way that does not conflict with the interests of society and the natural environment. In this regard, one of the effective ways to control and minimize the damage and consequences of land use is to adapt its structure so that, based on the characteristics of land resources and their capabilities, the land can be spatially distributed and arranged more rationally. This study aims to identify and zone the appropriateness of land use structure with the existing capabilities in Hamedan and to evaluate the efficiency of the multilayer perceptron neural network method in the field of land use structure optimization in this city.Materials and Methods In this study, to adapt the land use structure in the city of Hamedan, based on the research background and according to the effective criteria in the field of land use structure, various indicators were selected, including 12 land use indicators, slope, average temperature, and average rainfall. Average humidity, average wind speed, geology, soil type, distance from the river, distance from wells, distance from main roads, and vegetation type. Then, using the field visit, the points with user suitability were registered as educational points. After preparing the layers of the mentioned indicators, these layers were standardized in the software environment of the GIS system. In the next step, the multilayer perceptron neural network uses the after-release algorithm by importing layers affecting the optimization of the land use structure as input and using the middle layer of distance. From appropriate points in terms of land use structure, this network was implemented with the structure of 1-10-12 to adapt the land use structure in Hamedan. From 35% of the total image pixels, the distance from the agricultural proportions as training points falls into three categories the first part (70%) for network training, the second part (15%) for stopping calculations when the error is increasing, and the third part (15%) was used for network verification. Finally, the final land suitability map was drawn. The resulting layer had a value between 0 and 1 which was divided into five land suitability classes. In the present study, after identifying the factors affecting the land use structure and adapting its structure, and preparing each of them, the mentioned layers were standardized. Then, using the field visit, the points with appropriate use were recorded as educational points. Thus, the land use structure was adjusted by the multilayer perceptron neural network model with 58 replications. The results of the neural network validation and the resulting output layer indicate the high accuracy of the network in fitting the land use structure so that the square root mean values of error (RMSE), and absolute error (MAE). Correlation coefficient (R2) in the implementation process of the network is equal to 0.19, 0.21, and 0.89, respectively, indicating the network's high accuracy in implementing the optimizing process. Completely inappropriately divided, and the results showed that most of the areas covered some somewhat suitable and perfectly suitable lands with 32.62 and 28.13% of the total area, respectively.Results and Discussion In the present study, after identifying the factors affecting the land use structure and adapting its structure, and preparing each of them, the mentioned layers were standardized.

Completely inappropriately divided, and the results showed that most of the areas covered some somewhat suitable and perfectly suitable lands with 32.62 and 28.13% of the total area, respectively.Conclusion The results of optimizing land use structure in Hamedan show that most of the area is not suitable for agricultural activities in terms of effective factors. In this area, most urban land uses completely barren and uncultivable lands, lands. There are mountainous, rocky, and low-quality pastures, mainly in the western and southwestern areas of Hamedan. Also, in this area, lands that have been relatively suitable in terms of a proportion are quite suitable in terms of 12 factors in the best conditions for agricultural and horticultural activities and are the best place for developing agricultural activities. Thus, to change the land use conditions towards a more appropriate trend while paying attention to integrated urban-rural planning for Hamedan and its surrounding settlements. It is recommended to pay attention to land use planning rural-urban plans and projects because the rapid expansion of Hamedan and its suburban spaces has created numerous challenges in terms of land suitability. In such a way that about 23.1% of the lands are ready to be transformed into unsuitable and completely unsuitable conditions. In addition, 32.62% of land use is subject to change to semi-suitable conditions. Based on what has been said, controlling, supervising, and directing the constructions and preventing the over-horizontal expansion of the city of Hamedan and its surrounding spaces by urban and rural stakeholders (local management) is proposed to rangeland and agricultural lands. The findings of the study also indicated that the highest area of land in this area is related to somewhat suitable and perfectly suitable land and the lowest area belongs to unsuitable and somewhat unsuitable land. Therefore, it can be said that the city of Hamedan is currently in a semi-suitable situation in terms of land suitability, which can have a more favorable trend in the future with proper planning and policies.

One of the most important decisions that must be made in production systems is determining the product mix. That means which and how much of the product should be made from it in order to increase the final output of the system. Often, in previously existing algorithms, all problem parameters are assumed to be certain and decision-making used to be carried out. The situation studied in this paper is that all the production parameters are in the form of triangular fuzzy numbers. Those production parameters include weekly demand, selling price, cost of raw materials, the processing time of products and the available capacity of resources. In the proposed algorithm, considering the multi-bottleneck, with the help of fuzzy Vikor, the prioritization of production is calculated. Finally, in order to explain the aforementioned method, a numerical example has been discussed.       Manuscript profile

In recent decades, urban policy-making has been raised as a significant and scientific topic in major cities of the world, and it has received several attentions from urban studies. One of the topics that is not paid attention to in climate approaches, especially in sustainable architecture, is the consideration of solar energy in buildings, but a lot of attention to solar energy has unfortunately caused that to some extent other renewable energies such as Wind energy and its significant impact on natural ventilation are passively neglected. Paying attention to this case can be taken into consideration by the officials in order to pay attention to the optimization of energy consumption in urban policy making. One of the effective solutions in this field is the use of natural ventilation in residential buildings, determining a suitable direction for creating blinds and receiving wind with positive pressure and benefiting from this influential climatic element in the interior spaces of the building. In this research, an attempt was made to investigate and simulate natural ventilation conditions in residential buildings in Shiraz using Vasari energy simulation software, and parameters such as wind speed, wind direction, wind temperature, and other influencing factors were investigated. and be analyzed. According to the results of the simulation and examination of the twenty-year average of the climatic indicators of Shiraz city, it can be said that if the issues related to natural ventilation and the creation of blinds in the building are considered and the optimal orientation angle can be obtained from solar energy and Also, use wind energy to reduce the load on the building's mechanical facilities throughout the year. that the optimization of energy consumption has been done and in the scale of residential buildings in the metropolis of Shiraz, it can lead to the reduction of fossil fuel consumption to a significant extent.

An integrative operating system consists of a surface water subsystem and groundwater subsystem. To satisfy water demands, these subsystems interact with each other. They will act as two parallel tanks that they can use each other's storage volume through sending the operating commands. This paper presents a simulation-optimization model for designing dimensions as a mass form whose components include periodic series.For more accurate results, water status relating to two years with eight seasons, in the  first year, the amount of water was more  than the second year, have also been studied. In this method, simulation method is placed in optimized model so that it forms a simulation-optimization model. The results, which were based nonliner programming, revealed that release from the dam reservoir will not necessarily be similar to non-consolidated model. Also based on the other results, we can refer to the optimized design of model components such as dams and wells and optimal usage command.   Manuscript profile

Background & Objectives: Milk and its products support the growth of infectious germs such as Escherichia coli, the most important agent of food contamination, in special conditions. This study was aimed to optimize the methods of identification of E. coli strains from ice cream based on 16S rDNA. Materials & Methods: In this cross-sectional study, 82 bacterial strain were isolated from 200 ice cream samples collected from different regions of Isfahan. Of these, 48 positive indole strains were isolated. The isolation was carried out based on Iran’s national standards (No. 2946) and using chromogenic media on a comparative basis. After numerical analysis, the 16SrRNA was amplified by PCR and the amplified genes were sequenced. Results: We observed that the method used in the national standard is 88 % reliable with 12 % error. Moreover, the positive indole strain such as Escherichia hermannii, Providencia rettgeri, Klebsiella oxytoca, Morganella morganii showed errors in the final result. Conclusion: We demonstrated that culture media containing chromogenic materials could identify Escherichia coli with a more accurate, simple, quick and inexpensive procedure. Manuscript profile
