Investigation of the effects of Covid-19 pandemic on UHI in residential, industrial and green spaces of Tehran Abstract Rapid urbanization in recent decades has been a major driver of ecosystems and environmental degradation, including changes in agricultural land use and forests. Urbanization is rapidly transforming ecosystems into buildings that increase heat storage capacity. Loss of ve...
Within the Anglo-American literature, commercial, along with residential, gentrification has often been treated as an attendant neighborhood phenomenon. This study aims to uncover distribution of areas for emerging consumption that indicate occurrence commercial gentrification, well explain development process and spatial correlations in Chengdu, a large Chinese city. With data points interest ...
a one dimensional dynamic model for a riser reactor in a fluidized bed catalytic cracking unit (fccu) for gasoil feed has been developed in two distinct conditions, one for industrial fccu and another for fccu using various frequencies of microwave energy spaced at the height of the riser reactor (fccu-mw). in addition, in order to increase the accuracy of component and bulk diffusion, instanta...
An approach is presented for detecting the buildings from high resolution pan-sharpened IKONOS imagery through binary Support Vector Machines (SVM) classification. In addition to original spectral bands, the bands nDSM (normalized Digital Surface Model), NDVI (Normalized Difference Vegetation Index), PC1, PC2, PC3, and PC4 (First, Second, Third, and Fourth Principal Components), are also includ...
The usage of social theories in the human-built environment caused to enhance life quality. It may consist of human needs in residential areas. Sometimes, building codes can help to exist accepted life space, but the building codes do not have basic theory such as actual open space in residential plots. The study was an attempt to represent a new approach in urban land subdivision and the relat...

flood is considered as a major threat among natural disasters in the world. this case becomes more important and has a higher risk in urban areas due to the existence of important uses. therefore, to reduce damages resulted from flood, this phenomenon must be managed and planned using structural and non-structural approaches. considering the development in iran has been carried out in high risk...
Extended abstract 1- Introduction An examination of the number of floods in recent years shows that floods are no longer a rare sudden disaster, but a growing phenomenon that, at any given time, causes a lot of damage, including life and death. As a result of interference in natural environments, the presence of multiple structures, and the lack of appropriate measures to protect these env...
attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
