Many different communities have conducted research on the efficacy of relevance feedback in multimedia information systems. Unlike text IR, performance evaluation of multimedia IR systems tends to conform to the accepted standards of the community within which the work is conducted. This leads to idiosyncratic performance evaluations and hampers the ability to compare different techniques fairl...

In this paper, the use of the blended learning pedagogy as a teaching environment is studied. This pedagogy is based on a mixture of collaborative learning, problem-based learning and independent learning. Also, it is realized as a combination of a face-to-face environment and online learning, using a proprietary learning management system. More precisely, the methodological approach implemente...

The simTD (Safe and Intelligent Mobility: Test Field Germany) research project is another step towards bringing Car-to-X technology to marketability. One of its envisioned applications is a Traffic Information System (TIS) based on selfgenerated maps for vehicles not equipped with digital maps. To assure reliable operation, the function itself, its performance and the effect of its input parame...

There are a v a r i e t y of f ac to r s that a f f e c t the performance of an expert system. This paper presents an eva lua t i ng method focus ing on the complex i ty , costs and e f f i c i e n c y of in ference s t r u c t u r e in a r u l e / Knowledge-source based expert system. The performance measuring fac to rs proposed here, when fedback to Knowledge engineers, can help them gain a q...

A software architecture is one of the first steps towards a software system. The design of the architecture is important in order to create a good foundation for the system. The design process is performed by evaluating architecture alternatives against each other. A desirable property of a good evaluation method is high efficiency at low cost. In this paper, we investigate the use of continuou...

This paper presents a new method to examine the performance evaluation of mutual funds in incomplete markets. Based on the no arbitrage condition, we develop bounds on admissible performance measures. We suggest new ways of ranking mutual funds and provide a diagnostic instrument for evaluating the admissibility of candidate performance measures. Using monthly data from 1984 to 1997, we show th...

In this paper we present the design details of the visual perception system in Aware Home. This paper is intend to (a) detail our design details; (b) provide insights on how different parts of the tracking system are inter-related to solve complex perception tasks; (c) document ideas and potential research directions; (d) provide performance evaluation. This work will primarily focus on algorit...

In the framework of the workshop ”Performance Evaluation of Computer and Communication Systems: Milestones and Future Challenges”, this paper proposes to address the emerging criteria of energy. Used since a long time in embedded systems where battery operated devices needed a careful handling, the energy metric is taking a large momentum in the last years on large scale systems where thousands...

Increasing complexity of current and future systems poses a new challenge for software engineers. In a previous work we presented a light-weight runtime system for abstraction of heterogeneous parallel systems. This runtime system adapts an application to the current system state in order to improve the utilization of the available resources. For online evaluation of such adaptions, we propose ...

Performance is determined by a system’s resources and its workload. Some of these resources are software resources which are embedded in the software architecture; some of them are even created by the software architecture. This paper considers software resources and resource architecture, as an aspect of software architecture, It considers how resource architecture emerges, the relationship of...
