In this paper a new approach for predicting the future channel situation on the basis of actual and past channel characteristics is suggested. Applying high resolution estimation techniques to the Time-Variant Transfer Function of the radio channel, a 2-D Fading Forecast based on parametric modeling is introduced. In contrast to existing methods this allows a small-scale fading forecast not onl...

Distributed applications deployed over the Internet, such as in grids, clouds, or P2P networks, crucially depend on the speed of their Internet connections. A common solution is to exploit underlying network parallelism via multipath routing within an application-level overlay network. Accurately selecting appropriate relay hosts within an overlay, however, remains a challenging problem, freque...

We present a new method for lossless image compression that gives compression comparable to JPEG lossless mode with about ve times the speed. Our method, called FELICS, is based on a novel use of two neighboring pixels for both prediction and error modeling. For coding we use single bits, adjusted binary codes, and Golomb or Rice codes. For the latter we present and analyze a provably good meth...

This paper presents an architectureindependent modeling infrastructure called the Energy Introspector for estimating non-functional aspects of processors such as energy, power, temperature, area, delay, sensor, and reliability. The Energy Introspector supports processor modeling through the integration of various modeling tools. It features structural abstraction of physical and microarchitectu...

Multiple sequence alignments are essential in computational analysis of protein sequences and structures, with applications in structure modeling, functional site prediction, phylogenetic analysis and sequence database searching. Constructing accurate multiple alignments for divergent protein sequences remains a difficult computational task, and alignment speed becomes an issue for large sequen...

Limiting casting expression speed was obtained and the flow redistribution thermal history in a horizontal direct-chill (HDC) predicted using numerical modeling approach. The governing solidification equations were non-dimensionalized to understand relevant contribution of each term processes HDC system. effect an increase on characteristics sump length represented by Péclet number Pe.

in this research paper, the performance of an air-cored axial flux permanent magnet synchronous generator is evaluated for low speed, direct drive applications using 3d finite element modeling and experimental tests. the structure of the considered machine consists of double rotor and coreless stator, which results in the absence of core losses, reduction of stator weight and elimination of cog...
