This paper addresses the mixed integer reliability redundancy allocation problems to determine simultaneous allocation of optimal reliability and redundancy level of components based on three objective goals. System engineering principles suggest that the best design is the design that maximizes the system operational effectiveness and at the same time minimizes the total cost of ownership (TCO...

entropy generation in an unsteady hydromagnetic couette flow of a viscous incompressible electrically conducting fluid between two infinite horizontal parallel plates in a rotating system have been analyzed. both the lower and upper plates of the channel are subjected to asymmetric convective heat exchange with the ambient following the newton's law of cooling. a numerical solution for governin...

This paper introduces MorphoSys, a parallel system-on-chip which combines a RISC processor with an array of coarse-grain reconfigurable cells. MorphoSys integrates the flexibility of general-purpose systems and high performance levels typical of application-specific systems. Simulation results presented here show significant performance enhancements for different classes of applications, as com...

| This paper presents a possible solution for the text inference problem-extracting information unstated in a text, but implied. Text inference is central to natural language applications such as information extraction and dissemination , text understanding, summarization, and translation. Our solution takes advantage of a semantic English dictionary available in electronic form that provides t...

The information technology (IT) world has changed fundamentally and drastically from running software applications on a single computer with a single CPU to now running software as services in distributed and parallel computing environment. Power system operation has been also shifted from being solely based on off-line planning study to more and more real-time market-driven. Facing these chall...

This paper presents a new approach to the solution of nonsymmetric linear systems that uses hybrid techniques based on both direct and iterative methods An implicitly preconditioned modi ed system is obtained by applying projections onto block rows of the original system Our technique provides the exibility of using either direct or iter ative methods for the solution of the preconditioned syst...

The ability of performance technology to keep pace with the growing complexity of parallel and distributed systems depends on robust performance frameworks that can at once provide system-specific performance capabilities and support high-level performance problem solving. Flexibility and portability in empirical methods and processes are influenced primarily by the strategies available for ins...

A parallel combinatory OFDM system (PC-OFDM) is proposed. The proposed system is able to obtain a higher bandwidth efficiency than an ordinary OFDM system. The bit error rate performance is analyzed and simulated. On a Gaussian channel and on known time invariant channels the PC-OFDM system can obtain lower bit error rates than ordinary OFDM. In some cases we can at the same time increase the b...

—Conventional sorting algorithms make use of such data structures as array, file and list which define access methods of the items to be sorted. These traditional methods – exchange sort, divide and conquer sort, selection sort and insertion sort – require supervisory control program. The supervisory control program has access to the items and is responsible for arranging them in the proper ord...
