In environmental studies, different types of system boundaries are needed. Disaggregated GIS data are crucial because they can be flexibly converted into the target boundaries. The National Oceanic and Atmospheric Administration (NOAA) data of Gross Domestic Product (GDP) should be highly evaluated as a valuable GIS data. We, however, show the problem that GDP per capita in urban areas is lower...

The paper aims to investigate land use change at the county level in Beijing-Tianjin-Hebei Metropolitan Region. Three land use patterns are identified by assessing the urban-rural linkages: urban, peri-urban and periphery areas. Empirical analysis shows that land use change in the urban areas is faster than that in the peri-urban and periphery areas. Economic conditions are significant to the l...

For the fast transient dam break flooding with floating bodies presented through intricate city layouts, the traditional grid-based method based on solving two dimensional (2D) Shallow Water Equations or three dimensional (3D) Reynolds-averaged Navier-Stokes equations have difficulty in modelling the 3D unsteady flow features and the moving objects in the flow, causing inaccuracies. In this pap...

Big Video data analytics and processing are becoming increasingly important research areas because of infinite generation of massive video data volumes all over the world. In this paper, by utilizing Bayesianbased importance analysis, we propose a set of novel, simple but effective video recording methodologies and intelligent algorithms to solve the so-called big video data volume problem in u...

People counting is a crucial and challenging problem in visual surveillance. Automatic monitoring of the number of people in public areas is important for safety control and urban planning. For this purpose many techniques and methods have been proposed. These techniques are not producing high performance and better accuracy for complicated scenes counting. Recently Foreground Extraction and Ex...

Abstract In 2013, UN-HABITAT provided the City Prosperity Index (CPI) to evaluate policies and guide urban decision-makers. Quality of life is one of the five dimensions of urban prosperity, which is one of the newest theories in the field of urban planning. The concept of urban quality of life has been invigorated in the wake of social welfare and social justice schools. In Iran, from the past...
