Distributed heterogeneous resources coordinated by fast networks provide a new platform for resource-intensive parallel applications. However, careful scheduling of such applications is required to achieve their performance potential. Since resource load varies dynamically, the scheduling mechanism may consider redistribution of application tasks to improve performance. In this paper, we focus ...

73.7 0.9 188.7 2.4 960 12 This paper describes a method to evaluate image applications mapped to a focal plane , processing array with a single pixel per processing element. An application is specified and compiled to a common instruction set architecture. The application is then simulated to create a dynamic workload. A design space of possible execution machines is compiled using predicted pe...

In this article we present a low cost 3 0 face modeling scheme that uses only an overhead projectoq a camera and a plane object. We deal with the calibration of such a system, the 3 0 face reconstruction itself; and then the texturing of the resulting 3 0 shape.

The increasing interests in using renewable energies are coming from solar thermal energy and solar photovoltaic systems to the micro production of electricity. Usually we already have considered the solar tracking topology in large scale applications like power plants and satellite but most of small scale applications don’t have any solar tracker system, mainly because of its high cost and com...

Intrusion detection systems need to maximize security while minimizing costs. In this paper, we study the problem of building cost-sensitive intrusion detection models. We examine the major cost factors: development costs, operational costs, damage costs incurred due to intrusions, and the costs involved in responding to intrusions. We propose cost-sensitive machine learning techniques to produ...

The value of a software system results from the interactions between its functionality and quality attributes (such as performance, reliability and security) and the market-place. Quality is a direct consequence of architectural design decisions. Traditional product cost models have focussed on the short term development cost of the product. We argue that if one wants to build realistic cost mo...

This paper offers an extrapolation of the manufacturing and service industries' Cost of Quality Model to the business of software development. The intent is to provide a theoretical account of the changing quality cost structure as a function of a maturing software development process. Thus, the trends in expenditures due to the four major quality cost categories --appraisal, prevention, intern...

Financial markets are considered to be liquid if a large quantity can be traded quickly and with minimal price impact. Although the idea of a liquid market involves both a cost as well as a time component, most measures of execution costs tend to focus on only a single number reflecting average costs and do not explicitly account for the temporal dimension of liquidity. In practice, trading tak...
