A comparative study of iterative solutions to linear systems arising in quantum mechanics
(2010)This study is mainly focused on iterative solutions with simple diagonal preconditioning to two complex-valued nonsymmetric systems of linear equations arising from a computational chemistry model problem proposed by Sherry ... -
Agile methods rapidly replacing traditional methods at Nokia: A survey of opinions on agile transformation
(2010)Context Many organizations have started to deploy agile methods, but so far there exist only a few studies on organization-wide transformations. Are agile methods here to stay? Some claim that agile software development ... -
Pattern-based software architecture for service-oriented software systems
(2010)Service-oriented architecture is a recent conceptual framework for service-oriented software platforms. Architectures are of great importance for the evolution of software systems. We present a modelling and transformation ... -
Multiple Descriptions Based on Multirate Coding for JPEG 2000 and H.264/AVC
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2010)Multiple description coding (MDC) makes use of redundant representations of multimedia data to achieve resiliency. Descriptions should be generated so that the quality obtained when decoding a subset of them only depends ... -
A Comparison Between ULP and MDC With Many Descriptions for Image Transmission
(2010)In this letter, we present a performance comparison between multiple description coding (MDC) and unequal loss protection (ULP) for progressive image transmission over lossy packet networks. Two optimization criteria are ...
