Urban heat island is among the most evident aspects of human impacts on the earth system. Here we assess the diurnal and seasonal variation of surface urban heat island intensity (SUHII) defined as the surface temperature difference between urban area and suburban area measured from the MODIS. Differences in SUHII are analyzed across 419 global big cities, and we assess several potential biophy...

An important element of Internet Things systems (IoT) is wireless data transmission. Narrowband (NB-IoT) and LTE Cat M1 (LTE-M) are the new standards for such transmission intended cellular networks. Cellular network operators has recently launched The article presents results measurements NB-IoT parameters in this network, inside building open urban areas. main features system measuring equipm...

tehran has been facing water shortage challenge for decades and it has not hesitated to exploit neighboring watersheds. rising demand and limited resources might make water crisis a strong possibility in the near future. an accurate and applied analysis of tehran's urban water system (uws) would be the first step to be taken to prevent such a crisis. this research is an effort to make an a...

knowing income inequality in socio-economic subgroups helps us to achieve justice. the main goal of this study is to evaluate, decompose and compare the theil and atkinson inequality indices in terms of the inequality within and inequality between urban and rural area in tehran province during the 3rd and the 4th economic development program of iran. doing so, we used the micro households'...

In this paper, the historical trend of urban growth and the associated drivers were examined through econometric analysis for the rapidly growing Grafton area in the State of Wisconsin. Specifically, panel data analysis was carried out to examine the drivers of urban growth such as demographic factors, location of jobs, travel time, housing types, property values, etc. Results reveal that panel...

This paper presents a new method for unsupervised urban area extraction from SAR imagery. The image segmentation method combines variogram texture feature extraction with OTSU threshold segmentation method, to obtain the result as good as traditional classical algorithm and have much higher computational efficiency. TerraSAR-X image is used to validate the proposed method, and experimental resu...

Our work encompasses subjects of urban planning, urban design, urban morphology, and the link between geographical information systems (GIS) and urban visualization. Our area of research focuses on the way people conceptualize the urban environment. The visualization technique discussed in this paper is an attempt to provide users with a tool to create their own sense of urban legibility, which...
