The paper proposes an implementation of the message passing algorithm adapted to iterative channel detection. The algorithm uses soft messages associated to non binary symbols in order to cancel cycles in the equivalent Tanner graphs, achieving optimal performance after a low number of iterations. This architecture, suited to very fast channel detectors, is applied to magnetic recording channel...

The use of voice prints, or spectrographic voice identification, has been around for several decades. This highly developed technology uses complex algorithms to break the speech signal down into its component parts: time, frequency, and energy. The result is a spectrogram, also known as a voice print, that allows visual or computer comparisons between two or more audio samples. Voice prints ar...

A multiplexer is a unidirectional device and used in any application in which data must be switched from multiple sources to a destination. The low power circuits have become a top priority in modern VLSI design. This paper presents the power consumption comparisons and delay of various designs of 2:1 Multiplexer. The various logic styles such as Differential Cascode Voltage Switch Logic (DCVSL...

This paper considers the steady state queueing properties of pedestrians who are delayed by traffic on a main road. It is assumed that the size of the gap between two successive cars dete rmines the probability that an individual pedestrian or a group of pedestrians will cross. The technique of imbedded Markov chains yields many new results as well as some previously found , by co mbinatorial m...

This deliverable was initially planned for december 2007 and was rescheduled for June 2008. It is composed of two papers, the first one, submitted to the neurocomp08 conference, and the second about to be submitted to a journal. Both detail the Bayesian eye movement selection model, which derives from the previous theoretical work presented in D2.2, and its results confronted with the experimen...

This paper presents pre-layout simulations of a proposed 8T full adder design using a proposed 3T XNOR gate cell. The proposed design remarkably reduces power consumption hence power-delay product (PDP) over various input voltages and frequencies. It also improves temperature sustainability as compared to the existing 8T full adder. This proves to be a viable option for low power and energy eff...

Novel contemporary healthcare information systems offer the prospect of exploring unique features of the IT artefact and probing the finer, integral relations between society, technology, and humans. Some of these IT artefacts are innately complex and current theoretical perspectives are too limited to enrich their understanding. Using material from a longitudinal case study of an Internet-base...
