Abstract
Urban highways, as one of the most important sectors of transportation, have always been one of the most challenging, both in terms of budget consumption and its spatial, social, economic and environmental impacts on the city. It has been urban elements. To this end, this study analyzes the impacts of inter-city highways, examines the theories of how to deal with this spatial element, as well as the factors involved. The type of research is applied-theoretical and the method is documentary-analytical. The sources of information used in this research are all documents, documents, books, articles, plans, and scientific research on urban highways. The results indicate that there are favorable and disagreeable views and views on the creation of inter-city highways. Modernist thinkers and urban engineers, advocates of urban highways, and later urban planners and geographers, are opposed to one-dimensional attention to these highways and inner-city development relying on highways. The results also showed that the inter-city highways had social, economic, physical and environmental impacts and, depending on the location conditions and the socio-economic characteristics of the location, these impacts were positive and negative in space. It looks around.

Abstract
Considering important role of housing in contemporary urban areas, evaluating urban housing quality has become one of the most popular topics in recent researches. Housing has vast conceptual perspectives which include many aspects of urban life beside the dwelling purpose of it, such as recreation, primary schools, and play yards and so on. The most efficient tool for achieving such purposes is evaluation of qualitative and quantitative urban housing indicators. Using quantitative, objectivistic, positivistic methods and models frequently observes in Iranian scientific journals recently. This article aims to study and evaluate such researches, using scientific analytic methods which have accepted and published in domestic scientific journals. The emphasis of this article is to review papers which studied urban indicators in any area in Iranian urban areas which published between March 2011 and September 2019. To do so, the PRISMA method (Preferred Reporting Items for Systematic Reviews and Meta Analyses) has introduced and applied and 39 papers have selected. These papers selected among all papers had indexed in Scientific Information Database (SID.ir) and Comprehensive Iranian Humanities Portal (ensani.ir) which include one of these keywords: housing indicator, urban housing. Complete information of these papers has cited and method, data resources and conclusion of each paper discussed briefly. Some criteria introduced and measured to evaluate different aspects of selected papers considering PRISMA suggestions. The most cited sources (papers, books, dissertations and statistic reports) have identified and applied in conclusion.
The results have shown that applying quantitative methods on urban indicators led to analogous assessments in various contexts and using novel methods and models, especially applying qualitative and mixed methods would resulted in novel and efficient perspectives to future urban housing programming and applying the PRISMA method would increase quality of survey reviews and strongly recommend to achieve comprehensive and qualified study of similar researches.

Abstract
Deterioration of urban textures is an issue that most cities in Iran are faced with and the organization of such textures is of great importance. One of the safest and most practical solutions for urban planners is to assess the feasibility of regenerating such textures to determine the levels that can be regenerated and are relatively good and tolerable for urban society. Therefore, the present study aims to investigate the feasibility of regenerating worn-out textures of Ilam City based on urban smart growth approach using a descriptive-analytical methodology. The statistical population of the study includes residents of central worn-out texture of Ilam city (population: 12676 people), 384 of whom are selected as the sample of the study using cluster sampling method. The data collection tool is a researcher-made questionnaire that has been confirmed by face validity and Cronbach’s Alpha coefficient, turning out to be 0.701. Data analysis is done using single-sample t-test, fuzzy multi-criteria analytical hierarchy process (fuzzy AHP), and its integration with GIS layers. The findings show that the condition of worn-out textures of Ilam city is unsuitable in terms of urban smart growth approach. Evaluation of the digital strata shows that some indicators (including size of the sections, access to services, main and secondary access points) are in a good condition and others (including unused land, population density, gender ratios, active population, employment rate, and literacy rate) are in a poor condition. Finally, the results show that 2.3 hectares of the worn-out texture of Ilam City, including 22-Bahman Square, Ashrafi Esfahani St. where it crosses Resalat Intersection, the northern edge of Moghavemat Intersection, the northern edge of Imam Square, and the area around Koudak Park, have the highest priority for regeneration and revitalization.

Abstract
Precipitation is a phenomenon resulting from complex atmospheric interactions and among climatic events, due to its vital role, it has special importance. The importance of precipitation durability, especially in arid and semi-arid regions, which includes most of Iran, is greater than its volume. The purpose of this study is to identify Iran's precipitation areas in terms of precipitation durability and its characteristics in each area. In order to investigate the durability of Iran's precipitation and to define a precipitation day as " a day with equal precipitation or greater than 0.5 mm", used from daily precipitation data of 80 synoptic stations of the country during the 6 cold months of the year from October to March in a period of 30 years (2016 - 1987). Setting data in daily tables in the first step, made possible to program in MATLAB environment to separate precipitation in ten groups from "one day" to "ten days" and in the second step in SPSS environment based on frequency characteristics, amount and precipitations average in the mentioned groups was done by the method of Ward merging and clustering. The process of the clustering on Iran's durability precipitation showed that there are seven almost homogeneous precipitation zones in Iran; the geographical arrangement of Iran's precipitation areas, reveals the dependence of Iran's precipitations amount on roughness, the path of precipitation systems, its proximity to humidity sources, and the effect of the sea. In terms of area’s location, it can be said that; the settlement of the four zones in the western half of Iran, despite its small size in front of the eastern half, is a reason for its heterogeneity.

Abstract
Mineral Dust, the most important type of aerosol, has a significant direct and indirect role in weather and climate. In this case, it intend to investigate the capability and capability of MACC model validated by MODIS for detection of dust episodes in the Kurdistan province during 2003-2012. To achieve that, we analysis satellite and model data using Man-Kendall trend and statistical tests. The results of the temporal distribution indicated that the mean Aerosol Optical depth (AOD) in 2008 was 0.36 and its lowest was 29.04 for 2004. In addition, average AOD in menthioned year was 0.036, 0.335, 0.385, 0.377 and 0.3368 for the cities of Sanandaj, Saqez, Ghorveh, Kamyaran, Marivan, respectively. The spatial distribution of AOD average in different seasons showed that winter and autumn had the lowest amount and spring, and summer season had the highest AOD. AOD's monthly spatial distribution showed that high dust belonging to April-August period to covers completely interested area.The results of the Man-Kendall test showed that the area had a significant positive trend in the spring season throughout the province and the summer season in the east of the province. Therefore, the spring season in the area known Extreme Season and June 19, 2009 between the five days of the dust extreme is as an extreme episode with an average AOD of 1.16 and a horizontal visibility of less than two kilometers that it have the highest and most widespread mineral dust. In general, the results of the MACC with multidimensional approach showed that optical depth (AOD, DOD) is a more appropriate criterion than horizontal visibility in determining dust storm.

Abstract
Historical contexts have rich cultural and cultural resources and are not very important not only because of the existence of valuable historical buildings and spaces, but also because they are real narratives of the life and activities of human beings who have lived throughout life. They lived in them themselves. Today, due to urban development and the blockade of the technology of historical textures, the issue of restoration of cultural and historical textures and the implementation of urban design projects in them has faced a double challenge of the intervention and protectionist approach. According to these two approaches, new constructions and contemporary architecture do not have enough identity to be included in the valuable urban contexts, and the process of burnout has been manifested more rapidly in historical contexts. The need to pay attention to the reconstruction and protection of historical contexts with a comprehensive approach and taking into account the physical, legal, environmental, economic and social dimensions is one of the objectives of the present study. This research has been studied in terms of practical purpose and with a qualitative approach and using content analysis method and to collect the required information and data, documentary studies and field studies have been used. The findings show that the neighborhood is worn out and to recreate the historical core of Qazvin city, the approach of urban revitalization and urban and strategic regeneration strategies is essential in line with the principles of sustainable development.

Abstract
In the past, architects in many parts of Iran had built traditional public buildings to create a community convenience and comfort. Ab Anbars are good example of this facility structures which they were suppose to collect water in rainy condition and keep it cool for use in dry condition of year espacialy in hot and arid climate. To study amount of radiation and heat absorption 2 Domes of Ab Anbar in Yazd (hot and arid climate) and 2 Domes of Ab Anbar in Qazvin (cold climate) were selected. In order to simulate the domes, they were first modeled in Revit software 2017, and then models were transferred to Rhino 5 software, using the honeybee & lady bug, and with the Energy plus Engine analysis of the received solar radiation and shading were done. In the analyzes, uniformity of the dimensions of the Ab Anbars domes were used, so that the optimum dome can be obtained in terms of receiving solar radiation and absorbing heat in the shadowed area. To equalize the domes, the absorption of the sun's radiation of each dome is divided by the amount of shadowing of the same dome.Radiation absorption in hottest day of the year in hat and arid climate and coldest day of year in cold climate were calculated using Energy Plus software Honeybee & ladybug Plugins. Result shows that amount of radiation is dependent to form of domes. During study day (14,16 and 18 o’clock ) 78, 71 and 64 percent of high rise Domes is facing radiation while 93,81 and 64 percent of low rise domes is facing radiation. From this results it can be concluded that high rise domes have better function in hot and arid climate and low rise domes have better function in cold climate in relation to radiation absorption.

Abstract
The aim of the present study is to dynamically model the spatial-temporal characteristics of dust in the south and southeast of Iran with REG-CM4 model using monthly dust data and RegCM4 data. For this purpose, the dust distribution of the IDW method along with the dust diagrams were plotted. The RegCM4 model was implemented with the paired Lambert image imaging system for 40 km horizontal separation with the paired chemistry model. The location of monthly and annual dust distribution shows the highest amounts of dust for the cities of Zabol, Bandar Abbas, Zahedan and Jask compared to Sirjan, Kahnooj and Lar stations. The highest frequency of dust in Sistan and Baluchestan (48%), Hormozgan (27%) and Fars provinces with 16% and the lowest frequency for Kerman province (9%). In general, the summer seasons (at Sistan station) and the winter (Kerman station) have the highest and minimum dust events, respectively. The time survey also has the highest amount of dust for the warm months of the year and the lowest for the cold months of the year. July at Zabol station and November and December at Sirjan station have the highest and lowest dust levels, respectively. The RegCM4 climate model also shows maximum dust on the southeast, south and south coasts for different variables.
