Abstract

Survey of advection of cold waves in Iran is the main aim of this study. In this regard, 45 synoptic stations were employed and studied. In order to investigate the thermal advection of cold waves, 1000, 850, 700 and 500 hp levels were reviewed and analyzed. Results indicated that cold waves in Iran most affected thermal advection caused by Tibet- Siberia, Siberias integrated Turkmenistan high-pressure, High pressure belt of Siberia - East Europe High pressure, Siberian high-pressure multi-core pattern and High-pressure belt of East of Caspian Sea integrated Black Sea High pressure. In the meantime, thermal advection of Siberian high pressure has been more impressive than other patterns. This system moved towards lower latitudes by anti-cyclone moving, So the cold weather of northern latitudes loss in lower latitudes North East of Iran, North West and Central parts of Iran. However, when Siberian high pressure combined with other patterns, its role in the advection of cold air have been considerable

Abstract

Today, due to the transformation of the form of life and the proliferation of quantitative, gradually the qualitative and semantic concepts of the spirit of neighborhood in the minds of residents are dimmed. Factors such as immigration, Changes in the social composition of the population, Continuity of residence and persistence in neighborhoods have diminished. With the lack of infrastructure refinement, due to the lack of local community in the process of identifying problems and accurately measuring their needs, has led to a sharp divide between the efficiency of the neighborhoods and the needs of the inhabitants of the establishment and the neighborhoods have led to inefficiencies. While some modern neighborhoods are planned in a short time. On the contrary, the process is moving traditional neighborhoods. The main question is that the standards of a lasting Iranian neighborhood are up to date, from the point of view of the main inhabitants? The purpose of this paper is to answer the question that, What are the criterias of Up-to-date of persistent Iranian neighborhood, from the perspective of the main inhabitants? This analytical-qualitative study uses the Grounded theory method, Purposeful sampling of 5 neighborhoods with the statistical population is 86 people (until theoretical saturation) from the main residents. By means of position analysis, the final criteria were fixed. The parameters of security, sense of place, social status, spirituality and modern technology are one of the most important criteria for the survival of residents. The results show that the neighborhood, from the point of view of the inhabitants, goes beyond the broad concepts of elitist rigidity, more often than not, in simple mental and intriguing indicators, which require the recognition of the social reality of the people and the real needs of their daily lives with the collaborative interactive planning approach The dialectical relationship is between the opinion of experts and the views of residents in order to refine and update the neighborhood. The manifestation of the concept of Persistent Iranian Neighborhood is updated on the basis of principles: efficiency, persistence, dynamism and continuity in the form of conceptual model.

Abstract

The aim of this study was to analyze the mechanism is precipitation Comprehensive Iran. For this purpose the daily precipitation data of 483 synoptic and climatology stations arranged. In this study, a comprehensive annual rainfall is said to have a minimum rainfall and above, 50% sequence coverage and have at least two days. Winter surround Iran on the condition of rainy days were extracted and examined. Then, to review and analyze the mechanism of atmospheric precipitation comprehensive synoptic and dynamic parameters such as moisture flux, vortices, ground level pressure, Geopotential, meridional and zonal wind component for the levels of 1000, 850, 700 and 500 HP studied and analyzed was. The results of this study showed that the widespread mechanism of dynamic and synoptic Winter country most affected by the composition of the atmosphere patterns such as the Mediterranean low pressure - low pressure core Persian Gulf, Iran, Central High East Europe closed low pressure, low pressure Urals - the Middle East, high pressure, low pressure Saudi Arabia - High pressure belt Europe and Siberia - Iran's low-pressure center. However most of the winter precipitation of moisture flux feed barley middle-Level interaction, particularly levels of 850 and 700 HP respectively. It was while change 500 hPa atmospheric dynamical mechanism is an important role in Iran's winter inclusive.

Abstract

 The purpose of the present study was to identify legal challenges to the implementation of regeneretional goals in areas of  urban decay, including those that were selected as pilot sites for the implementation of regeneretional goals after the recent laws on regeneretion. In order to investigate the challenges of implementing regeneretional goals, first the theoretical basis of the research is formulated the necessary process in urban decay legislation, then a questionnaire based on the necessary indices in each dimension and based on the opinions of 50 experts from the Organization for Development. Reproductive Company and Friedman's one-sample t-test and analysis of the effect of different dimensions on the realization of regeneretional goals in the laws and by developing the desirable criteria of legal goals based on the views of the professors and Delphi method, content validity of the later rules. The results indicate that measures taken by the redevelopment laws in the Sirus neighborhood have indirectly driven groups of residents to the outskirts of the city. This challenge stems from the imbalance between property rights and citizenship rights and the public interest. The emphasis on land acquisition and liberalization and the implementation of regeneretion projects have neglected the provision of public and collective benefits and created challenges in other social, economic and managerial dimensions, and the failure to achieve regeneretion goals. Therefore, by presenting strategies to strengthen the theoretical and fundamental dimension of the subject of civil rights, the research aims to provide the necessary framework for reforming the legislative process and providing a platform for the implementation of regeneretional goals.

Abstract

A new urbanism theory has emerged in recent decades in response to numerous urban problems of the twentieth century, with the goal of creating vibrant, compact, diverse and desirable cities in terms of work, walking, life, and transportation options. In view of the widespread acceptance of this theory among the Iranian researchers, the aim of this study is to assess the sustainability of organic and planned neighborhoods in Mashhad based on the spatial-physical indexes of new urbanism. In this regard, two neighborhoods, Rah­Ahan (organic neighborhood) and the second phase of Rezashahr (planned neighborhood) were selected. This research method is descriptive- analytical and the mixed model of AHP and GIS has been used to assess the stability of two neighborhoods. Accordingly, the Sustainability Measurement Model was used as a hierarchy in the form of 7 physical-space indicators (type of road, pedestrian width, land use, area of lots, access to the center of the neighborhood, number of floors and access to public transport) . Tthe research results show that in Rezashhar, 68.43% of neighborhood area has moderate to high stability and 31.57%  of the total of the neighborhood area is the lack of stability, and in Rah­Ahan, 70.84%  of the total of the neighborhood has moderate to high stability and 29.16% of the total of the neighborhood is lack of stability. Therefore, according to the spatial indicators of the new urbanism, the neighborhood of Reza Shahr is more unsustainable than the old neighborhood of Rah Ahan. Therefore, this study shows the richness of traditional Iranian urbanization and the superiority of old neighborhoods. So, it can be said that traditional and organic urbanization is a more appropriate basis for applying the new urbanism approach and this approach can be used in the form of urban regeneration.

Abstract

One of the issues facing today's cities in Iran is the issue of maintaining and upgrading existing streets. The way of managing theses streets and dealing with them has caused various problems in different aspects of cities. The purpose of this research is investigating the principles of maintenance and promotion of urban streets with a focus on Islamic teachings and Iranian culture. This research also explains some ways to improve the quality of urban streets using Islamic teachings and Iranian culture. Gathering information was done through observation, field study and documentary studies. Using content analysis methods, documenting and graphical analysis, information and data were analyzed. The quality of the cities depends on the quality of the streets and the quality of the streets is also based on the details of the streets. After designing and constructing urban streets, they need attention, maintenance and promotion in order to be always attractive and desirable for citizens. The results of this study indicate neglecting the indigenous material, art, culture, religion, needs and interests of citizens which has led to the construction of unqualified urban spaces in the metropolitan areas of today's Iranian cities. This research did not seek to provide a template for urban streets designing, but it is in direction of developing principles of planning and designing urban streets based on Islamic teachings and Iranian culture. In addition to having appearances according to Islamic teachings and Iranian culture, desirable street for Iranian citizens should also be Islamic and Iranian internally. With Just the correctness of appearances it can be said that only hypocrisy is obtained, but with internal reforming, honesty can be created in urban spaces.

Abstract

It is important to examine the effect of the tourist personality on the choice of tourist destination. In the meantime, using Hofstede's cultural model in analyzing the effect of tourist personality dimensions on the intention to visit through the perceived homogeneity variable greatly helps to understand this issue. In this research, the effects of femininity, masculinity, ambiguity, avoidance of individualism and collectivism on the intention to visit have been analyzed. This research is applied in terms of purpose and methodological in addition to descriptive and survey research. In this regard, 384 questionnaires were distributed among tourists from German, Japanese, French, Arab (Iraqi), Italian, Austrian, Chinese nationalities residing in five star hotels in Tehran. Structural equation index was used for data analysis. The results show that tourists prefer brands that match their perception of the destination brand. The findings of the study indicate that the personality dimensions of the tourist intent through the popularity of tourism destinations and the image of tourist destinations influence on the perceived homogeneity of the urban tourism brand and the masculinity of the tourism city brand; Perceived homogeneity of urban tourism brand is effective and femininity of tourism city brand does not affect perceived homogeneity of urban tourism brand. The results of this study indicate that Tehran has a masculine brand and people are selected to be masculine and to be collectivist and ambiguous. In fact, the results of the study showed that in selecting tourism markets for Tehran, one should look for tourism markets that are characteristic of the Hofstede model in terms of masculinity, ambiguity and collectivism, as well as the development of tourism spaces for women.

Abstract

Today, the number of elderly people is increasing due to various factors such as changing life expectancy and population distribution. On the other hand, this period of life requires special needs such as care and health to other external and environmental factors. The social phenomenon of the city is not separate from this population group, ie the elderly, and urban planners using environmental theories can take steps to improve the use of the elderly in the city and its public spaces. In this regard, the purpose of this study is to explain the components of the elderly-friendly city with an environmental psychology approach in the eight cities of Shiraz. After identifying the characteristics to obtain the required information using a questionnaire tool that Cochran's method was used to determine the sample and GIS data were generated using Moran analysis of the desired layers and then using hierarchical analysis and Hot spot analysis of overlapping criteria was performed using fuzzy functions and urban spaces needed by the elderly were identified. Then, by confirming the hypotheses in this field that attention to social components along with components of spatial structure can be appropriate to improve the urban environment, suggestions in this area from attention to access and public transportation to creating an environment Elderly entertainment was provided.

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.
