A subspace-based approach to Lagrange-Sylvester interpolation of rational matrix functions
(IEEE, 2005)In this paper, we study Lagrange-Sylvester interpolation of rational matrix functions which are analytic at infinity and propose a new interpolation algorithm based on the recent subspace-based identification methods. As ... -
Performance of real-time data scheduling heuristics under data replacement policies and access patterns in data grids
(Springer-Verlag Berlin, 2006)A variety of real-time data scheduling heuristics were proposed for distributed, data intensive real-time applications running on a distributed computing system. The proposed heuristics are used to produce real-time data ... -
Biobjective scheduling algorithms for execution time-reliability trade-off in heterogeneous computing systems
(Oxford University Press, 2005)A heterogeneous computing (HC) system is composed of a suite of geographically distributed high-performance machines interconnected by a high-speed network, thereby providing high-speed execution of computationally intensive ... -
Object reconstruction from in-line Fresnel holograms without explicit depth focusing
(Spie-Int Society Optical Engineering, 2004)We propose two computational techniques for extracting object cross-sectional shape information from digitized in-line Fresnel holograms that do not require prior knowledge of object depths but recover relative depth ... -
Adaptive polyphase subband decomposition structures for image compression
(IEEE-Inst Electrical Electronics Engineers Inc, 2000)Subband decomposition techniques have been extensively used for data coding and analysis. In most filter banks, the goal is to obtain subsampled signals corresponding to different spectral regions of the original data. ... -
