BACKGROUND Prior research has reported disparities in environmental exposures in the United States, but, to our knowledge, no nationwide studies have assessed inequality in noise pollution. OBJECTIVES We aimed to a) assess racial/ethnic and socioeconomic inequalities in noise pollution in the contiguous United States; and b) consider the modifying role of metropolitan level racial residential...

Fractal image coding has the advantage of higher compression ratio, but is a lossy compression scheme. The encoding procedure consists of dividing the image into range blocks and domain blocks and then it takes a range block and matches it with the domain block. The image is encoded by partitioning the domain block and using Affine transformation to achieve fractal compression. The image is rec...

The main contribution of our work is in combining the methods for parametric urban design of highly specialized software such as CityEngine and general-purpose parametric modeling platform such as Grasshopper. Our work facilitates and prompts the use of parametric tools by architects and planners for urban design. In this paper we present a custom grasshopper component for street network genera...

Abstract On the basis of elaborating connotation intensive city block, it is pointed out that structure organization key to realize block. The order complexity block formed by close connection, overlapping elements, depth difference and their compound association. This paper constructs basic pedigree design from three levels street configuration, plot building layout, forms derivation comprehen...

Urban green space (UGS) can be regarded as an effective approach to mitigate urban heat island (UHI) effects. Many studies have investigated the impacts of composition and configuration UGS on land surface temperature (LST), while little attention has been paid among different blocks. Thus, taking 1835 blocks in Beijing samples, including low-rise point (LRP), street (LRS), block (LRB), mid-ris...

Radiative balance and heat storage capacity modifications play a major role in urban heat island formation. Urban shape determines the receipt and loss of radiation and consequently the heat storage potential, thus resulting in a higher air temperature. In order to analyze the interactions between climate and urban shape, the territory is partitioned from the road network into elementary areas:...

Original scientific paper The model proposed in this paper is based on a multi-criteria analysis of annual daylight illumination relying on the interoperability of commercially available software tools. The daylight performance of different urban morphologies is investigated by simulating and measuring real weather conditions for a specified location on two types of 3D models. The first analysi...

The influence of urban design on economic vitality has been analyzed by a number of researchers and is also a key focus of many planning/design theories. However, most quantitative studies are based on just one city or a small set of cities, rather than a large number of cities that are representative of an entire country. With the increasing availability of new data, we aim to alleviate this g...

In this paper, the historical trend of urban growth and the associated drivers were examined through econometric analysis for the rapidly growing Grafton area in the State of Wisconsin. Specifically, panel data analysis was carried out to examine the drivers of urban growth such as demographic factors, location of jobs, travel time, housing types, property values, etc. Results reveal that panel...
