A fundamental purpose of traditional land-use controls is to exclude undesirable land uses from residential communities. However, such regulations have been shown to limit the ability of low-income households and people of colour to find suitable housing in decent neighbourhoods.

An optical tomography system is developed for generating three-dimensional reconstructions of thick objects from projections. The system is useful for studying transparent structures that are 1-10 mm in diameter. Evaluation of the reconstruction system with a test object demonstrates 98% geometric accuracy, 90% accuracy in the detection of boundaries, and(More)
Resolution of biomagnetic images using the technique of the alternating projections is proposed. Our image reconstruction procedure is divided in two steps. First, the biomagnetic inverse problem is solved by use of the projection theorem to reconstruct an initial image of the current distribution from a given magnetic field profile. Although the current(More)
INTRODUCTION The tens of billions in federal stimulus funds for transportation, coming to states and regions at a time of substantial budget difficulties, adds urgency to the question " what is the best use of transportation dollars? " Transportation touches all aspects of our communities, but the current economic downturn and the stimulus have placed an(More)
Bus rapid transit (BRT) in the United States is relatively recent. BRT has many promises , one of which is enhancing the economic development prospects of firms locating along the route. Another is to improve overall metropolitan economic performance. In this article, we evaluate this issue with respect to one of the nation's newest BRT systems that(More)
