In a context of globalization, municipalities and metropolitan regions are involved in international competition to support economic growth. This leads to new forms of collaboration between public authorities and businesses, giving birth to new forms of urban and metropolitan governances. Moreover, many old neighborhoods of the central city and some districts of the old suburbs face growth in u...

Ahmad, Shaikh.M.S.C.E.,Purdue University, December 2014.Capacity-Related Driver Behavior on Modern Roundabouts Built on High-Speed Roads. Major Professor: Andrew Tarko. The objective of this thesis was to investigate the factors that affect capacity-related driver behavior on modern roundabouts built on high-speed roads. The capacity of roundabouts is strongly affected by the behavior of driver...

This paper develops a set of quantitative variables to characterise urban forms at the metropolitan level and, in particular, to distinguish compactness from ‘sprawl’. It first reviews and analyses past research on the definitions of urban form, compactness and sprawl, and corresponding quantitative variables. Four quantitative variables are developed to measure four dimensions of urban form at...

Although invasive pneumococcal disease (IPD) accounts for only a minority of the infections caused by Streptococcus pneumoniae (such as pneumonia and otitis media), it is associated with the most severe disease and is readily measured, as it is by definition associated with a sterile site isolate. The Metropolitan NSW Pneumococcal Study Group was formed in 1997 to generate data describing the a...

Crushed serpentinite quarried in Montgomery County, Maryland, has been extensively used for paving roads and other surfaces. The mineral assemblage includes antigorite or lizardite as well as chrysotile and tremolite. Air samples taken in the vicinity of serpentine-paved roads show that chrysotile concentrations are about 10(3) times greater than those typically found in urban ambient air in th...

Classifying roads in remotely sensed imagery has been addressed by a number of research efforts. Detecting these features is important for a variety of endeavors such as agricultural assessment and urban planning. This study investigates the viability of using a pulse-coupled neural network to recognize roads in Landsat-4 Thematic Mapper multispectral imagery.

The ceaselessly increasing number of trips on urban highways and major arterial roads have caused serious congestion and air pollution problems. Thus many transportation agencies have persevered in their efforts not only to alleviate such problems, but also to minimize social costs. However, the complex nature of such problems has strongly hindered transportation agencies’ ability to consider a...

With more and more vehicles equipped with GPS tracking devices, there is increasing interest in building and updating maps using vehicular GPS traces. Most existing approaches for building maps rely on position traces from highly accurate positioning devices, which are sampled at a high frequency, e.g., every second. Typically these traces are recorded by survey vehicles. Commodity GPS devices ...

STUDY OBJECTIVE Despite significant declines since the late 1960s, coronary mortality remains the leading cause of death for African Americans. African Americans in the US South suffer higher rates of cardiovascular disease than African Americans in other regions; yet the mortality experiences of rural-dwelling African Americans, most of whom live in the South, have not been described in detail...
