This study estimates the effect of the online gaming industry on the commercial casino gaming industry. The findings from this study suggest that during the pre-UIGEA period, online gaming was a moderate substitute good for brick and mortar gaming in the U.S. During this early period in the online gaming market, which was characterized by loose regulation and relatively easy access, online gami...

This paper presents the modular robotic system SafeBot to air autonomous nuclear security applications. This research serves many Department of Energy applications for inspection and surveillance in hazardous areas. Currently four kinds of sensors are available through the SafeBot robotics system: laser ranger sensor brick, thermal sensor brick, visual sensor brick and gamma and neutron sensor ...

Interior brick-infill partitions are usually considered as non-structural components and only their weight is accounted for in practical structural design. In this study, their effect on the progressive collapse resistance of an RC building subjected to sudden column loss is investigated. Three notional column loss conditions with four different brick-infill locations are considered. Column-los...

The effect of artificial pozzolan (waste brick) on the physico-chemical properties of cement manufactured was investigated. The waste brick is generated by the manufacture of bricks. It was used in the proportions of 0%, 5%, 10%, 15% and 20% by mass of cement to study its effect on the physico-chemical properties of cement incorporating artificial pozzolan. The physicochemical properties of cem...

The emergence of electronic commerce raises important questions about the building and leveraging of legitimacy for both practitioners and scholars of strategy. New entrants’ click-and-mortar or click-and-click business models are challenging the legitimacy of large and mature brick-and-mortar incumbents. The implications of this challenge for the financial services industry—as for many other i...

In this paper, a mobile scanning system for real-time under-vehicle inspection is presented, which is founded on a “Brick” architecture. In this “Brick” architecture, the inspection system is basically decomposed into bricks of three kinds: sensing, mobility, and computing. These bricks are physically and logically independent and communicate with each other by wireless communication. Each bric...

BACKGROUND Numerous malaria epidemics have occurred in western Kenya, with increasing frequency over the past 20 years. A variety of hypotheses on the etiology of these epidemics have been put forth, with different implications for surveillance and control. We investigated the ecological and socioeconomic factors promoting highland malaria vectors in the dry season after the 2002 epidemic. ME...
