No unique method has been so far specified for determining the number of neurons in hidden layers of Multi-Layer Perceptron (MLP) neural networks used for prediction. The present research is intended to optimize the number of neurons using two meta-heuristic procedures namely genetic and hill climbing algorithms. The data used in the present research for prediction are consumption data of water subscribers in Fasa City of Fars Province (Iran) between the years 2010 to 2013. Ultimately, using the respective data set, the data of the subsequent year 2014 can be predicted. In the present research it was observed that the mean square errors of per data (MSEPD) for the abovementioned algorithms are less than 0.2, indicating a high performance in the neural networks’ prediction. Correlation coefficients using genetic and hill climbing algorithms were respectively equal to 0.891 and 0.759. Thus, GA was able to leave a better effect on optimization of neural network.

Urban farms can have the potential to have a great impact on the stability of crowded cities. The purpose of the present study is discovering the effective design-based components in developing urban agriculture in the viewpoint of Tehran’s urban managers. It is assumed that the design-based development of urban agriculture improves economic conditions and also food security for Tehran’s citizens. A combination of qualitative and quantitative research methods were used in this research. In the qualitative section of the research, analysis of the influential factors was carried out.

Quantitative analysis of the data was carried out using the SPSS 22 statistical software. The results showed that establishing and developing design-based urban farming could lead to elevated qualities of environment, food security and economic well-being more than any other factor.

Nowadays, one of the topics of interest to researchers is the authority of teachers, and fades it in universities. Look at the reality in the society and comparing with historical context motivates researchers to question why some of the professors at the university have less authority. For this purpose, this research is trying to focus on economic and demographic factors, to answer questions. The method used in this research is descriptive analysis using survey techniques and data collection tool is a questionnaire. The population consisted of professors of Kermanshah PNU in the academic year 2011-2012, total number of them is equal to 258. Due to the large size of the population, using the Lin sampling table sample size is 258, which for the study based on striated random sampling were selected. In the present study, face validity assessment method and construct validity based on factor analysis were used. To determine the reliability of the statements of each variable, Cronbach's alpha used. Results using SPSS21 and Amos21 statistical software were analyzed. Mean traditional authority equal to 13.57, then charisma authority13.54, and intellectual authority is 18.72. The dimensions compared with the average expected for above dimension respectively traditional authority 15, charisma authority 12, intellectual authority is 15. The results show that there is a significant relationship between relative deprivation and professor’s authority (r=-0.301), the use of mass media and professor’s authority (r=0.161), monthly income and professor’s authority (r=-0.153). In addition, the results of comparison show that average of the professor’s authority among the courses is different, and this difference based on f test is significant. The average professor’s authority, for people with different degrees is different. The results of Multiple regression indicate that the traditional authority (T=4.335), self-esteem (T =3.925), charismatic authority (T =3.788), and the relative deprivation (T =-2.287), total 0.42 from internal changes explain the value of professor’s authority variables. Furthermore, the results of structural equation shows that Chi square insignificant CMIN is equal to 211.143, square root index mean residual square or RMSEA is equal to 0.075, RMR index or residuals mean square root is equal to 0.098, the Chi-square to the degrees of freedom ratio CMIN.dF in model is 3.199, against the CFI comparative fit index 0.926, and comparative fit index thrifty PCFI, are equal to 0.671 Comparative and thrifty indicators for evaluating the overall model calculated that show collected data to support the theoretical model considered.

Historical fabric of Arak, as one of the most important inorganic cities in urbanization history of Iran, has been implemented from the beginning based on predetermined plan and project. During the age that majority of cities in Iran used to be created organically and gradually based on public needs, all steps of construction of Arak City including spatial organization, physical structure, communicative network system, activity distribution pattern and composition of urban elements were firstly designed and then implemented. The main objective of this study is to identify and analyze the physical features of monuments of Arak city to discover the behavioral system of monuments with the composition features standard. According to the research objective, the method applied is descriptive, analytical and comparative method based on field and library investigations. In this study, first architectural composition features including scale, proportion, hierarchy, axis, focus point, composition center, modulus, flexibility, rhythm and geometry are analyzed in each monument. Then, the monuments were classified in sub-factors of each composition feature and then, through comparing the classified groups, common features of monuments in each sub-factor with most frequency are extracted. The results obtained from the study showed existence of unit behavioral system in special groups of monuments compared to architectural composition features leading to typology of Arak’s historical monuments.

Land use is often referred as the basis for urban planning. Perhaps the main reason is that the discussion of fundamental related to urban planning objectives has play the first role in the land use studies. Basic topics such as proper location, optimal allocation, diversification, functionality and &hellip which are in direct contact with comfort goals, are the last objectives of urban planners and designers. One of the major issue, which has been paid less attention to, is the incorporation of urban land use. In this paper, which were prepared to assess the incorporation of urban land use and its role in urban sustainability, tried to measure the rate of the incorporation of seven metropolitan areas of Ahvaz by using the Shannon entropy and the latest statistics of related to per capita and percentage of exist land use. The results indicate that the region number one is incorporation than the other regions in terms of land use incorporation, but in general this indicator in the seven regions had little effect on urban sustainability.
