A novel image-based approach for detecting pedestrian crossings to enhance the safety and mobility of blind people while crossing a road is described. This is achieved through bipolarity-based segmentation and projective invariantbased recognition. A thorough evaluation of the proposed approach was conducted using 100 real images with and without crossings. It was found that the proposed techni...
This paper examines entrepreneurship in order to analyze, first, the degree to which the opportunity to start or own a business affects the household’s saving behavior and the implication of this behavior for the distribution of wealth and, second, the relationship between the extent of entrepreneurship in the economy and socioeconomic mobility, that is, the movement of families across wealth c...
One of the outcomes of massive adoption of technology is that much of daily technology use and consumption is embedded into “unremarkable” daily life routines. Occasionally, these routines undergo major shifts, often in conjunction with major life events such as marriage, birth of a child, or a residential move. We propose a model of settling into a new location as a function of balance between...
Why does the level of economic activity vary so much across space? One reason given is “agglomeration economies,” meaning that a firm’s or household’s production costs (of market and home goods, respectively) are lower when production is carried out in close proximity to other firms and households. In this paper I explore, via a quantitative spatial macroeconomic model, the contribution of aggl...
