zahra hejazizadeh

Climate predictions have been made in global, regional and local simulation, and climatic parameters have changed in terms of trends and models in climatology, futures studies are less visible in literature and climatology literature therefore environmental planning and futures analysis are an attempt to look at the long-term future in the field of climatology. Today, one of the most important challenges of the present and future is the increase in temperature and is the lack of climatic comfort. The growth of Tehran's metropolitan area, improving living standards, expanding urbanization and industry, climate change, and the energy shortage crisis are important. The survey forms were prepared by the climatologists and managers of Tehran and data analysis, futuristic techniques such as scenario for data analysis tool in this study was MICMAC software. have been used. In the research process, the most important key factors and drivers in relation to futures studies were identified in relation to the increase of temperature in the city of Tehran.

Mini scenarios and a comprehensive scenario were defined in three cases:

Improvement of the Micro-Climatic Conditions of Tehran City + Climatic Comfort of Citizens
Lack of good micro-climate in Tehran + low climatic comfort of citizens
The lack of improvement in the micro-climatic situation in Tehran + the lack of climate comfort for citizens and increased energy consumption

According to the results of the study, the most important factors in creating a crisis of rising surface temperature can be the lack of attitude to the concept of micro-climate improvement and urban management.

The coastal are geographically diverse from important areas for attracting populations and economic activities, especially military ones. Understanding the natural environment's behavior on the coast can help plan and deploy military activities. Therefore, this study evaluates the role of natural factors (climate and geomorphology). For this purpose, the most important variables affecting the location of military activities are selected, and then the data of the weather stations of the region for a period of 30 years to create climate databases and layers of features of the earth's surface including slope, tilt, topography, etc., for The formation of natural databases was selected and organized in the GIS environment. Then, using decision-making methods (AHP, ANP), we evaluated the impact criteria in the locational process. Ultimately, using the Fuzzy Collaborative Model, the final map provided the best places to deploy military equipment and equipment on the coast of the Oman Sea. The results showed that more suitable locations are located in the eastern coastal strip and some western locations. However, scattered locations with the least vulnerability and non-operational basics can be found in the coastal areas in the final map.

Mahmoud Reza Anvari

The physical development of a city will cause growth in other areas. Undoubtedly, the physical development of a country is an important factor in creating the dynamism of the economic system and even the well-being of its people. In this regard, Local governments need the variable, stable and sustainable financial resources for their role in this area. One of these sources is "taxes". The impact of tax on urban physical development plays an important role in its economic and social growth. In the meantime, taxes, especially the tax of estates and tenements, are one of the most reliable ways to provide resources for physical development. Therefore, the purpose of this study is to Investigating the Process of Urban Physical Development with Emphasis on Real Estate Taxes (Case Study: Five regions of Zahedan).The current approach to the present research is qualitative and quantitative and the type of research is applied. In this regard, comprehensive studies were conducted on the research indicators in the study area. The Fuzzy Mamdani model is then used to analyze the information. The results of the model function of the ranking of indicators indicate that public health and environment indices are in a desirable condition, Housing indices and quality of access are at a moderate level and educational, commercial, entertainment and recreational indicators are at an unfavorable level. The results of the status of the studied indices in determining the physical development of each of the 5 study areas in Zahedan in the output of the fuzzy inference system in the MATLAB software show that the 5th region with a score of 0.82 and first area with a score of 0.79 have a desirable level. The 4th area with a score of 0.70 has an average level of physical development. As well as the 2nd area with a score of 0.61 and third area with a score of 0.50 have an undesirable physical development.

ali akbar shayan yeganeh

Water is one of the most vital human needs. Chromium is one of the heavy metals that causes water pollution in different regions. The studied area is Joghatai Mountains and Davarzan, Khoshab, Joghatai, Joveyn and Sabzevar plains of Razavi Khorasan Province. This research has studied, analyzed water pollution with the element of chromium as well as the impact of lithology mountains Joghatai, on the quality of water in the region from the point of view of chromit. In this research, 13 samples were collected and tested by atomic spectrometer method.To check the amount of chromium present in them by comparing the findings with standard limits. The results of this study show that the amount of chromium in the selected water sources varies from 1.2 to 1.3 mg / L. Geochemical samples vary from 210 ppm to 4700 ppm. The lithology of the region especially the chromium mines has affected the quality of water but the density of faults and fans did not affect the amount of dissolved chromite. The effect of the slope of the geological layers is positive and the role of acidity in the pollution is poor. Finally, the amount of chromium in some samples is higher than the standard limit and should be considered by the custodians.

Fariba Esfandyari-darabad

Most of residential areas, population centers, and agricultural lands are located along the rivers and especially on the river terrace, which are affected by river dynamics, discharge changes, and flood hazards, bed fluctuations and meander variations. Therefore, it is necessary to study the behavior and pattern of meander movements of rivers in order to avoid potential hazards. The current research conducted in a reach of Gharehsou River in Ardebil province and the field measurements were done at adjacent to Anzab village to the Samian Bridge. In order to determine the pattern of this river, the Leopold Sinuosity Factor and the central angle calculated using Cornice method were used in this study. The results showed that the average of the Sinuosity Factor in the study area was 1.47, Which indicates the high ratio of river sinuosity. It also indicates the spatial variation of meanders evolution is not the same over the studied reach. The values of obtained Sinuosity factor using the employed methods showed that the %71.11 of meanders (32 meanders) with sinuosity factor of 1-1.5 belong to the category of low meander degree. While, the %17.78 of meanders (8 Meanders) had the sinuosity factor of 1.5-2. The remained 5 meanders (%11.11 of the identified meanders) had the sinuosity values greater than 2. This means that there are at least 5 meanders in the study area that are susceptible to becoming an oxbow-lake. Therefore, it is necessary to stabilize the stream banks and river bed of the study reach through structural management and engineering methods.

sadegh besharatifar

The present research is applied and its method is descriptive-analytical and correlational. For data collection using documentary and field methods, using service and socio-economic indicators as well as using quantitative models and statistics models Space is in the year 1397. The purpose of the research is to analyze and evaluate the spatial inequalities in utilization of urban services in Abadan oil. The results show that the economically-socially developed districts and the distribution of urban services are mainly central areas around the refinery dependent on the oil industry, which are merely due to the dependence on the oil company employees and the support of the oil company and the standards and privileges required therein Most of the indicators are necessary and, in the opposite direction, the other parts of the city, which have been created organically as a result of the activities of the oil industry, lack or are deprived of the necessary facilities and services. From other research results, there is a positive, strong and significant relationship between economic and social development with the development of urban services in Abadan city, so that the existence of planned oil industry sectors that are both economically and socially progressive, both in terms of physical and service Planned areas and the existence of marginal areas, especially in eastern areas of Abadan, which are both socially and economically weak and vulnerable, and in terms of physical development, have been less concerned with urban management, the effect of this form of unfavorable and unfair distribution of indicators Urban services lead to some sort of separation And spatial inequalities been in Abadan

The Implementation of TSP Algorithm in Optimization of the Movement Path of the Mobile Medical Laboratory During the Post-Earthquake Using GIS, ACO and ICA Algorithms (Case Study: Gorgan City)

Mohammad Hosein Saraei

The route optimization process is one of the analyzes that can be used when there is a constraint on resources and time, including post-earthquake conditions. In this research, this analysis has been used to solve the Travelling Salesman Problem. In this case, the goal is finding the shortest path between a set of points and the algorithm will try to minimize the transmission costs and target function. This paper due to target, is practical and developmental, due to doing method is descriptive and analytical and due to information gathering method is documental and surveying. In order to implement this problem, by considering to the strict scenario of accessing resources, two algorithms including the Ant Colony Optimization and Imperialist Competition Algorithm in the MATLAB environment with the Dijkstra algorithm in the GIS environment have been used. The view points of the model are areas that prepared to temporary post-earthquake settlement in Gorgan city and the spatial and temporal real-time distances in the urban network are used instead of Euclidian distances. The results of the implementation of the model have shown that the Ant Colony Optimization has performed the route optimization in two parameters of time and distance more effectively than the two dijkstra and Imperialist Competition Algorithm.

View of intra-city differences and its position in explaining the factors affecting the identity of urban space using logistic and differentiation methods. Case study: West and East regions of Mashhad

mostafa amirfakhriyan

Identity, as a complex concept, influenced by a variety of factors, makes one thing distinct and unique. Meanwhile, the characteristics of the environment, habits, worldview, cultural characteristics, etc., have a growing influence on the formation of these indices of identity. In other words, this study seeks to investigate the hypothesis of the difference in attitudes of inhabitants of the eastern and western parts of Mashhad towards urban identity indices and, finally, whether the distinction is observable or not? The basis of this study is based on quantitative methods that have been used for research purposes, along with qualitative methods. The output of this discussion is to achieve the identity of the city and its classification according to the purpose of the study. But in the small part, the study method is based on the use of differentiation and logistic models to show the type and level of differences between the eastern and western parts of Mashhad. Based on this, the rank of indicators of urban identity components was obtained in the form of a questionnaire in two categories of eastern regions (regions 4, 5 and 6) and western regions (including 1, 9 and 11) from the residents' perspective. The completed questionnaires were entered into the statistical database and analyzed using statistical software such as Excel and Spas. Study shoes that: 1- Regarding the formic index, studies show that variables such as high buildings, traditional architecture and natural form of place are variables that cause segregation of residents of eastern and western parts of Mashhad. 2- The results in Function indices also indicate that variables of vibrant places, places with activities, boarding times, places with different uses, and safe places are meaningful. 3- Finally, regarding the semantic indices, the effective and differentiating variables in the eastern and western regions of Mashhad, including two variables of understanding the sense of pilgrimage and understanding the characteristics of Islamic culture. Accordingly, it can be said that the attitudes of residents of the studied areas are different from those related to the sense of pilgrimage and the characteristics of Islamic culture in their. the end

Knowledge of the earthquake in architecture and its impact on the organization of the geography of habitation

Ali Asgharzadeh

Earthquake and its related phenomenon are often considered as the causes of instability and disorder in engineering and architecture, and have resulted in the destruction of many buildings and urban fabric. Despite this, by changing our attitude to earthquake: by redefining it from problem to potential and from chaos to complex organization, a different layer of this phenomenon can become evident. Earthquake and fault lines can be considered as an organizing factor, which play an important but hidden role in the geography of habitation, e.g. settlement location, urban spatial network, urban development and spatial-structural network of buildings. This article adopts a holistic approach and quantitative-qualitative methodology to identify the role of self-awareness and mental imaging in the complex system of earthquake-qanat-city and its effects on urbanism and architecture in different scales, which has resulted in an earthquake compatible architecture in different periods in the history of Iran and in some contemporary examples too.

Investigating the relationship between the sense of belonging to the place and the level of social security of citizens - Case study: Qom-

Hamidreza azemati

Human behaviors and activities of individuals are created in urban spaces, and cultural and social relationships are formed in these spaces. Considering the main source of insecurity among citizens in the cities and the important factors such as the physical form of the city, urban structures and the shape of buildings in this case, the purpose of the study is to measure the effect of the sense of belonging to the place in increasing the level of social security of citizens City of Qom. The research method is descriptive-analytic, and the questionnaire has been used to collect the field studies. The results of the research indicate that spatial relationships and spatial arrangements in the neighborhood environment with the control and social abnormalities along with the physical and physical environment have a significant correlation. Similarly, the type of form and the size of space, which is another component of the sense of belonging to the place, has a solidarity with social abnormalities and freedom of movement. The texture and decorations of the neighborhood space have a correlation with physical and physical environment. Among them, the most correlation between dimensions of sense of belonging to place and social security is related to the freedom of movement component with the form type and space size of 0.980.

sayyed mohammad hosseini

In this study, used the data of the Modis satellite. Satellite in the province of Hamadan for a period of 15 years to study and monitor the status of the leaf area index. The leaf area index data were analyzed. After extraction from the Modus website, coding was done in software and then extracted from the maps. Finally, the annual time series of leaf area index was obtained and its relation with rainfall and average temperature during these years. In order to investigate better, the cells above the one representing a better condition and higher leaf area density. In this regard, the years 2002, 2008 and 2011 were (0.01, 0.03, and 0.03%) of the lowest pixels higher than 1 and 2016 with 0.24 and 2014, 2009 and 2010 with 0.07 pixels higher than 1, the highest number of pixels. The common aspect of all years shows that in terms of pixels above the common places, all the years: the southern Hamadan gardens in the south of the Moradbeyk Valley, the Nahavand West fields, the south-east Malayer Gardens, the protected area Lashgar in the south-east of Malayer. The only difference seen in different years is the number of pixels. Finally, the time series of the data were the highest in 1389 and the lowest level of leaf area in the years 1381 and 2008.

Smart Urban Mobility and Social Sustainability: Exploring the relationship(Case Study:Shiraz City)

Jamal Mohammadi

Our country Iran is not far from the global changes of cities. One of these changes is the smart mobility that is Undeniable and inevitablein urban management today. Especially in metropolises, which are facing increasing population and various economic, social and environmental problems. In fact, metropolises always have many problems, most importantly transportation. Shiraz, as one of the major cities and one of the major cities of the country, has a special place. This position is of different cultural, historical, political and other aspects. Its population growth rate has also been steadily increasing due to its location. This trend of population growth over the past few decades has created problems and obstacles for sustainable and desirable management, most notably problems in the transportation sector. The same trend illustrates the need to emphasize smart systems in this city. Therefore, in this study, it is attempted to investigate and analyze Smart Urban Mobility and Social Sustainability for Shiraz. The research method is descriptive-analytical and based on documentary and origin studies. The results show that the mobility and displacement variables are in poor condition based on different dimensions of access, sustainable transport as well as ICT. Different indices of each of these dimensions point to the same issue, as its level of evaluation (significance level less than 0.05 and average lower than the criterion) points to their undesirability from the point of view citizens. The study of the impact of smart mobility indicators on Social Sustainability also shows that smart mobility indicators account for 23% of the total variance of Social Sustainability. On this basis, it should be noted that the mobility variable does not have an appropriate position in Shiraz, and this has not only affected its development process in recent decades, but also poses many challenges for its future development. The growing trend of the population and on the other hand the various social and cultural features as well as tourism are evolving in such a way that it requires a major focus on a systematic transportation based on smart city approach.

Investigation of the Relation between South and Southwest Iran's Heavy Rainfall with Atmospheric Rivers (ARs).

kamal omidvar

In this study, we tried to identify the sources of moisture and its direction of heavy rainfall in south and southwest of Iran by using a new algorithm based on atmospheric rivers. For this purpose, daily rainfall of 17 synoptic stations in the period 1986 to 2015 in south and southwestern Iran that have a common time span and fully cover the study area is used.Also from the data set of the National Center for Environmental Prediction / National Center for Atmospheric Research (NCEP / NCAR) European Mid-Term Forecast Center (ECMWF) and ERA-interim data with spatial resolution of 0.75 It was used at 0.75 latitude and longitude with 6 hour resolution. The variables used are integrated water vapor (IWV), specific humidity (q), and orbital and meridional components (u, v). In this research, an algorithm based on the calculation of Vertical Horizontal Vapor Transfer Integral (IVT) is used to identify and navigate atmospheric rivers. The results show that the main source of rainfall moisture is in south and southwestern Iran, south of Red Sea and Gulf of Aden. Of course, the maps show that the Arabian Sea was not affected by the humidity.The Arabian Peninsula also, due to the high moisture transfer rate, as a transitional route, transmits a large amount of moisture to the study area.Finally, the path of moisture to the study area was mapped and identified, and thus considering the three main conditions for the atmospheric river, it can be said that the path obtained is the same as the atmospheric river.

Identifying the semantic components that influence the creation and promotion of sense of place in high schools (Case Study: Boys' High School in District 1, Tehran)

jamaleddin honarvar

Today, the process of developing and constructing educational spaces tends to be more inclined to physical dimensions and is painted against human beings and their characteristics. The result is a disconnect between the students' relationship with the schools in particular and the educational environment in general. As such, they consider their students to be less part of the high school and feel less attached to it. The purpose of this study is to focus on designers 'view of the semantic levels of the school environment that can influence students' sense of place. The research method was descriptive, analytical and survey using spss software and Lisrel 8.8. This study uses the confirmatory factor analysis technique to determine whether the number of factors and loads of variables measured on these factors are consistent with what is specified in the theory. According to the results of confirmatory factor analysis, the standardized coefficients are acceptable and relatively large. Through the SEM structural model, it was estimated that the highest correlation and consistency between subjective factor with factor loadings of 0.76 and physical component rank second. With a factor load of 0.63 and finally the educational component with a standard coefficient of 0.58 establishes and promotes a sense of belonging in high schools. At the end of the conceptual model the research was mapped using structural equation modeling and by regression it was concluded that subjective, physical and educational components predict 43% of the variance in sense of belonging in Tehran high schools.

Of the 29 impacts evaluated, the estate has had 16 positive and 13 negative impacts.

Validation of summer temperature interpolation methods in northeastern Iran

Muhammad motamedi

The basis of climatic data is measurements taken at a predetermined chronological order at air monitoring stations, so all measured values of climatic elements can only be attributed to the point of measurement. Therefore, different interpolation methods can help a lot in estimating climate data in different places. The study area in this study is northeastern Iran, including the provinces of Khorasan Razavi and North Khorasan, and monthly summer temperature data were used for 21 synoptic and evaporative stations in the northeast belonging to the Meteorological Organization and the Ministry of Energy with appropriate distribution. The statistical period of 21 years (1997-1997) was considered as a common statistical period for all stations. Then, in order to compare the interpolation methods, several different methods, including ordinary kriging, spline, inverse squares and Thyssen were used by ARCGIS software. Comparing the deviations of the estimates from the measured data was evaluated by cross-validation. Then, in order to check the hypothesis of normality of the calculated errors in each interpolation method, the test thigh test was used and finally, to evaluate the best interpolation method, AHP method and Expert Choice software were used. The results showed that based on the root mean square error (RMSE) criterion, Thyssen, Kriging, inverse distance and spline methods were located, respectively. Based on the absolute maximum error criterion (MAE), the kriging method estimates the summer temperature better than other methods. According to the MBE standard, the kriging method is better than other methods and can be used for temperature interpolation. According to the set coefficients, the calculated compatibility rate is 0.03, which indicates the high accuracy of the selection of weights.

Evaluation of the Performance of Proposed Model of “Service Table” in the Management of Metropolitans from View Point of Urban Good Governance (Case Study of Tehran Metropolitan)

Amir Mahmoudzadeh

Tehran metropolitan authorities have always tried to develop the most efficient model for managing Tehran metropolitan affairs. Currently, the Tehran city management model is the council-city model, according to which people elect the members of the city council by direct vote, and the Tehran City Council elects the mayor. Over the past years, and considering that the institutions and organizations in charge of managing and providing urban services have in some cases suffered from parallel work or even inconsistencies in tasks, there is a need to develop a model for integrated urban management. In this article, descriptive-analytical method has been used. This article is practical in terms of the purpose of the study. The purpose of this article is to achieve a model for integrated management of Tehran metropolis. The statistical population of this study is Tehran urban management experts for which 34 people were selected as a sample. The data collection tools of this research are interviews and questionnaires and the data have been analyzed using paired comparison and TOPSIS methods. As a result of this research, according to the identified challenges and using TOPSIS method, the efficiency of the developed research model (with the proposed name of service desk) compared to the current model of Tehran urban management has been confirmed. Also, the most important result obtained from comparative studies is that in the studied metropolises, all matters of governance and urban management are always under the command of one institution and parallel work has been avoided, which should also be considered in Tehran.

Investigating the Effectiveness of Livability Indicators Using the Partial Least Squares Approach; Case study: Central part of Bojnord city

foroogh khazaee nezhad

Today, most of the world's population lives in cities, and urbanization, as the dominant phenomenon of human life, has continued to grow. But in recent years, the lives of city dwellers have faced many problems. In recent years, urban experts are looking for a solution for these problems, in which different theories, views, approaches, and models have been proposed. One of the most important approaches is the livability that is related to sustainable development. In this study, the relationship between different indicators of livability and its nature is explained. The central part of Bojnourd city has been selected as the case study. This research is a practical, desk and field study. Structural Equation Modeling with partial least squares approach and related software were used for data analysis. The results of the research showed that although there is a significant relationship between most of the indicators studied in this study and the viability, the local participation, educational facilities, and leisure facilities have had the greatest impact on livability. It was also found that there is a significant statistical relationship between residence time and identity (P = 0.01) and duration of residence and individual participation (P = 0.08) (90% confidence level).

moslem seyed alhossaini

Generally speaking the existence of metropolises, alongwith the high various business districts have led to high valume of travels to these centers.The density and separation of these centers brings about the increase and the decrease of the vehicles. The adoption of location determination strategies and that of the comunicational centers and the city activities has made the cities continue the developement process while cosidering the fairly service destribution and the spatial equalities.The goal of this research is the recognition and determination of the city spatial organization working centers and activity model and the relation of service functioning with one another so that the mono central and poly central cities can have a important effect on the destribution system and service centers and the vast changes of the citizens .The analysis method is a kind of quantity and quality one. In the quality part of that the descriptive statistics ( the geometrical presentation , graphical disparation, the centralism measures) and the Hansen Model. In the areas of planning, a great difference is seen in the levels of land uses so that the land use of higher educations in the western metropolitan city of Mashhad area is 84 percent while that of the eastern area is 3 percent. It is the same about the equipped medicinal, commercial and green space areas.Only in the areas of managerial levels there is a relative balance. Finaly the city is devided by three areas throughwhich while considering the employment , the developement potential and distance , the land use determining rate was found out.

Exploring the Mechanisms of Understanding Islamic City among the Citizens of District 20 in Tehran Using Structural Equation Modeling

hosein mojtabazadeh

A review of the history of the Islamic period reveals that concepts such as Islamic values and principles have always been one of the foundations of Islamic cities. This has made the Islamic city a space for the development of other Islamic fundamental concepts and principles. However, with the emergence of modern thinking and the emergence of numerous movements, we have seen that many of these are distorted. considering the historical background, values and factors present, district 20 in Tehran, is of no exception. In this regard, the purpose of this study is to investigate the mechanisms of how each of the factors of the Islamic city influence the perception of the inhabitants of this historical district of Tehran. To achieve this goal, a conceptual model of the research was first developed using the literature as well as the research context in which the three main physical, social and validity dimensions were considered for Islamic urban planning. Subsequently, using a questionnaire survey and its analysis by structural equation modeling, the effect of each of these factors on their indicators was put forth as the research findings. The results of the analysis indicate that the "validity" factors have the most impact on people's perception of the Islamic city, while the "social and civil" and "physical" factors are less influential.
