Urban neighborhoods are one of the vital elements of each city and the culture of urban residents is concealed in the texture and sinew of that .The advent of new technologies in urban life and percipitance of designers for construction of buildings led to reduce of fixation sense about their living environment and decrease social interaction. once the historical districts are regarded as symbo...
In urban context, urban nodes such as amenity or hazard will certainly affect house price, while classic hedonic analysis will employ distance variables measured from each urban nodes. However, effects from distances to facilities on house prices generally do not represent the true price of the property. Distance variables measured on the same surface are suffering a problem called multicolline...
There are three underdeveloped components of urban cloud-to-ground lightning studies: (1) the integration of multiple flash descriptors into more informative summary metrics of flash production, (2) the comparison of flash patterns by thunderstorm type, and (3) the correspondence of urban flashes with underlying land use. We used a GIS to integrate these components as part of an analysis of war...
today the image of a permanent skeletal space of cities affected by some forces or mechanisms is put in time with social-economic development and while imposes a new face and perspective to physical anatomy of cities, and prepares field to changes in content and social- economic structures of cities too. simultaneously with quitting villages in order to settle in cities by villagers, the phen...
the rapid and sprawl development city in recent decades has created many problems for cities and causing instability in urban environments. the late twentieth century these problems caused a revision in urban planning models and introduction of new models such as the infill development. studies show that third world countries like iran are faced with sprawl development model and should take the...
Due to the inherent discrete nature of sensing, interpolation is a key activity in sensing. Interpolation in urban computing faces an unprecedented inference issue that was not present in large scale traditional sensing environments. Obstacles such as buildings and walls are prevalent in urban sensing, and it is important to consider them in urban sensing interpolation. This paper introduces an...
With the rapid increase in world population that is concentrated in cities, expansion of suburbs and horizontal spread of cities has been accelerated rapidly and the scale of urban planning crisis in many parts of the world has been expanded. Hence, compact urban development paradigm for achieving sustainability and social justice and space were considered. Accordingly, this paper tries to expl...
Recent experimental work has shown that the average flow and average density within certain urban networks are related by a unique, reproducible curve known as the Macroscopic Fundamental Diagram (MFD). For networks consisting of a single route this MFD can be predicted analytically; but when the networks consist of multiple overlapping routes experience shows that the flows observed in congest...
Earnings Instability and Earnings Inequality in Urban China: 1989–2006 This paper investigates the evolution of earnings inequality in urban China from 1989 to 2006. After decomposing the variance of log of earnings into transitory and permanent two parts, we find that both components are important contributors to the total variance of earnings. We also find that the share of the transitory par...
