This paper presents VSim, a framework for the visualization of 3D architectural and archeological models. VSim’s design focuses on educational use and scholarly collaboration, an approach that is not commonly found in existing commercial software. Two different camera control modes address a variety of scenarios, and a novel smoothing method allows fluid camera movement. VSim includes the abili...

Chapter Eight of the NDP is the specific departure point for this research report as it deals with “transforming human settlement and the national space economy”. The Chapter gives strong emphasis to the importance of spatial transformation in addressing concerns with poverty and inequality. It argues that “where people live and work matters” and that “despite reforms to the planning system, co...

This paper illustrates how large instances of the linear ordering problem can be effectively modeled and solved as unconstrained quadratic binary programs (UQP). Computational experience comparing a basic tabu search code for UQP to the state-ofthe-art commercial code (CPLEX) demonstrates the viability and attractiveness of our approach.

This case examines issues in the assessment and adoption of Internet technologies in a federal U.S. government context, and describes in detail a pilot project to determine the feasibility of adopting an ASP solution to support procurement by multiple federal agencies using a variety of different legacy transaction systems. The pilot test of the Internet Payment Platform (IPP) by the eMoney gro...

White organic light emitting diodes (white-OLEDs) have shown the potential to replace commercial sources for lighting applications because of their high effi ciency and superior color quality. The most conventional architectures used to maximize the performances of such devices consist in the employment of three kinds of emitting phosphorescent or fl uorescent molecules and modifi ed glass subs...

Flow through mixed flow compressor stage was evaluated theoretically to understand internal flow behaviour. Various shroud configurations in terms of clearance has been considered to see the effect of clearance on compressor performance. The blade to blade relative flow variation from impeller inlet to outlet was evaluated through theoretical analysis. A 3D viscous commercial code Fluent was us...

Mayuram S. Krishnan e-mail: [email protected] Ph : 412-268-5799 PhD Student Graduate School of Industrial Administration Carnegie Mellon University, Pittsburgh PA 15206. Abstract Once a software product is delivered to a customer, the quality of service provided plays an important role in retaining that customer. In this paper, we identify certain key factors that impact the service quality in...

Television advertising is widely used by companies to promote their products among the public but it is hard for an advertiser to know if its advertisements are broadcast as they should. For this reason, some companies are specialized in the monitoring of audio/video streams for validating that ads are broadcast according to what was requested and paid for by the advertiser. The procedure for s...

Safety-critical systems are becoming more widespread, complex and reliant on software. Increasingly they are engineered through Commercial Off The Shelf (COTS) (Commercial Off The Shelf) components to alleviate the spiralling costs and development time, often in the context of complex supply chains. A parallel increased concern for safety has resulted in a variety of safety standards, with a gr...

This paper presents an empirical research to study synchronous and asynchronous collaborative design in a technology-mediated situation. In this experiment we wanted to create a design situation where four distant designers had to communicate using commercial software and standard hardware configurations. Our methodological approach gave us the opportunity to examine two main lines of research ...
