Abstract
Abstract This study was carried out to investigate and shed light on the complex theoretical concept of place, as a continuing dynamic phenomenon, in architecture. To this end, it has looked into the historical evolutions and retrieval of the Shah Wali complex in Taft. Considering the topic and the goal of this research paper, the morphological analysis as a tool used in the interpretive-historical research the method and the process of change and continuity of form was selected. The findings of this study indicate that this place, as a form, has always been subject to change. These changes could be categorized into two groups: (a) the changes which have been gradual and have taken place over a long period and (b) those which have taken place over a short period. The gradual changes have taken place starting from the Timurid to the Safavid era, at which point the complex has reached completion and evolved as a complex. After the initial developments of the complex, the complex underwent some short period changes in its components and spatio-temporal structure. These short period changes coincides with the demolishment of the old Takiya and construction of the new Takiya. Following these short period changes, the gradual changes of the second stage starts. As an implication of this research, it is suggested that urban designers and conservationists in particular revisit the theoretical underpinnings of the terms and concepts in the process of continuity and change of the historic dynamic complex, in order to fully understand and apply appropriate strategies in the design and the conservation.

Abstract
A city which is developing is a successful city and one which is not is considered to be an ailing, shrinking city. In the past, cities faced many demographic changes caused by wars, natural disasters and epidemics. Nowadays, cities experience huge demographic changes, too. In this regard, urban shrinkage is defined as long-term population loss which leads to decline in a city or a city center. Urban suburbs also have a significant effect on transitioning the population from cities to suburbs; this study aims to analyze the attractions of Abouzar town in Mashhad as a suburb and study its relationship with urban shrinkage. Methodology of this study is descriptive and analytical and data are gathered through scientific sources and using a questionnaire. The population of the study consists of the inhabitants of Abouzar town who had left Mashhad and taken residence in this town. Using PASS software package, a sample size of 350 was determined. The questionnaire data were analyzed suing SPSS22 software package and Smart PLS was used for modeling. Analysis of the attractions of Abouzar town revealed that social status, with 5 indices, has the most influence on the attraction of Abouzar town. Moreover, Spearman's test showed that a significant positive relationship exists between attractions of Abouzar town and leaving the city.

Abstract
Intraurban land-use change and factors affecting it are critical subjects in land-use planning. If unplanned, such changes can reduce the quality of life and spatial justice and ultimately lead to urban unsustainability. This paper aims to identify factors influencing unsustainable land-use change and analyze the intensity of such changes based on those factors. The artificial neural network analysis was employed to model the significant factors. The results indicated that the dynamics of the economy and the capital markets, a boom in the land and housing market, government interventions in the urban texture, gardens, and infill land have a dominant role in determining the rate of change in urban land use. According to the results, relevant indexes of the land and housing market and political and economic factors play a crucial role in Tehran's unsustainable land-use change.

Abstract
Urban planning and morphology are one of the most important factors affecting land surface temperature (LST) and microclimate chrematistics. The production of anthropogenic heat, mainly for cooling systems and lighting, has resulted in significant impacts on the quality of the thermal environment. These impacts include poor air quality, increased temperatures, higher energy consumption, and the development of urban heat islands (UHIs). With the growing urban population and increased building height, especially in metropolitan areas, there have been significant changes in the urban geometry, rate of pollution, amount of heat released, and meteorological parameters. All these factors contribute to the heat island phenomenon and significantly alter the microclimate in urban areas. The goal of this article is measuring the effects of height changes in buildings around Tehran metropolitan squares in a detailed plan on microclimatic changes. As part of a research study, the Hafthoz Square in Tehran was chosen as a case study. The researchers used a combination of simulation techniques (Envi-met) and GIS to detect the spatial variation of Land Surface Temperature (LST) and determine its quantitative relationship with building height and density. This was achieved through simulation modeling for the Narmak neighborhood of Tehran. As Conclusion, the results indicate that comparison on the simulation between the existing conditions and proposed scenario area showed that in the proposed scenario, wind speed and relative humidity decrease and ground surface temperature (UHI) and PPD and PMV indices increase. Therefore, if the detailed plan of Tehran metropolis is realized and implemented in many squares, it will be accompanied by changes in micro-climatic parameters in order to reduce the thermal comfort of citizens.

Abstract
Shrines, as part of the most magnificent works of Islamic art, not only play an essential role in the social life of cities but also reflect the architecture and arts of their time. Sometimes, these buildings are grouped and have been constructed over various periods. In the present study, the shrine of Al-Kadhimiya is examined. The
Al-Kadhimiya shrine complex, located in Baghdad, includes the tombs of two Shiite Imams. The construction of this complex began in the ninth century. The oldest inscription in this collection dates back to 1519 AD. According to historical evidence, the structure was built during the Safavid period. However, the construction rules, proportions, and principles of covering the space, as well as the design of the dome and the surrounding porch, incorporate pre-Safavid (Azeri) and Timurid art styles. This raises the question: how can a comparative study of the dome of the Al-Kadhimiya shrine with similar examples from the Timurid period prove that the change in artistic styles is a gradual process and not necessarily subject to changes in government? Therefore, this study examines the following hypothesis: the historical discontinuation of governments does not directly affect the architectural structures related to the subsequent period, which instead follow a gradual developmental course. This article employs a historical research method and comparative analysis. It compares the Al-Kadhimiya shrine with two complexes: the shrine of the eighth Imam of the Shiites in Mashhad, Iran, and the tomb of Shah Nematullah Vali in Kerman, Iran, as well as other Timurid domes. The results indicate that architectural techniques and structures are not necessarily updated with changes in government but follow a gradual process.
