The paper analyzes the ongoing urban transformation and delineates an underlying rationale which enables the comprehension of the current dual character of the Arab city with particular reference to the case of Eastern Province of Saudi Arabia. The re-reading of city form is mainly based on the critical interpretation of the mechanisms of urban morphology in relation to both global economic imp...

Background: Inclusion of inhomogeneity corrections in intensity modulated small fields always makes conformal irradiation of lung tumor very complicated in accurate dose delivery.Objective: In the present study, the performance of five algorithms via Monte Carlo, Pencil Beam, Convolution, Fast Superposition and Superposition were evaluated in lung cancer Intensity Modulated Radiotherapy plannin...

In the major U.S. and European cities (e.g., Detroit, Seattle, San Francisco, London, Paris, etc.) that since 2007 have been feeling the effects of the international economic crisis, regeneration processes have been set up thanks, among other things, to the synergic impact generated by urban agriculture (UA). There are numerous and greatly varied effects, linked to localization, that are consis...

Land use planning is always officially implemented as an effective tool to control urban development and protect farmland. However, its impact on land use change remains untested in China. Using a case study of Hang-Jia-Hu region, the main objective of this paper was to investigate the influence of different land use spatial control schemes on farmland conversion and urban development. Comparis...

Based on features on digital map, such as building contour and road polyline, we are proposing the system to generate 3-D Urban Model automatically, integrating GIS and CG. 3-D Urban Model is the important information infrastructure that can be utilized in several fields, such as landscape evaluation, urban planning, civil engineering, architecture, disaster prevention simulation, etc. When a r...

while risk reduction has been mainly addressed by seismologists and engineers by now, the total impact of earthquake greatly depends on urban planning factors. the effects of planning can be considered in the socio economic and physical aspects. urban planning may have a dominant role in various earthquake phases: at the time of earthquake; rescue, and emergency, as well as temporary and perman...

The rapid expansion of urban construction land has become the major characteristic of urban land-use change in China today. Meanwhile, the rapid urbanization process has led to the great changes of urban landscape in China, and it also has had certain impacts on environmental factors such as climate, soil, hydrology, biodiversity, etc., then it has made the overall ecological environment deteri...
