Urban Wind Corridors Analysis via Network Theory

Identifying urban corridors : unified concept and global analysis

Fast-growing spatial expansion and merging of urban areas on a global scale generate new forms such as megacities, mega-regions or urban corridors [e.g. UN-Habitat 2009; Florida et al., 2007]. With populations exceeding tens of millions, extents of hundreds of kilometres and the crossing of water bodies as well as international boundaries, these areas pose new challenges to authorities includin...

Transportation Corridors in Pacific Asian Urban Regions

analysis of power in the network society

اندیشمندان و صاحب نظران علوم اجتماعی بر این باورند که مرحله تازه ای در تاریخ جوامع بشری اغاز شده است. ویژگیهای این جامعه نو را می توان پدیده هایی از جمله اقتصاد اطلاعاتی جهانی ، هندسه متغیر شبکه ای، فرهنگ مجاز واقعی ، توسعه حیرت انگیز فناوری های دیجیتال، خدمات پیوسته و نیز فشردگی زمان و مکان برشمرد. از سوی دیگر قدرت به عنوان موضوع اصلی علم سیاست جایگاه مهمی در روابط انسانی دارد، قدرت و بازتولید...

Approximating Urban Wind Interference

A new approach is demonstrated to approximate computational fluid dynamics (CFD) in urban tall building design contexts with complex wind interference. This is achieved by training an artificial neural network (ANN) on local shape and fluid features to return surface pressure on test model meshes of complex forms. This is as opposed to the use of global model parameters and Interference Factors...

seismic vulnerability analysis of urban roads network

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...
