Power-Efficient Sensor Placement and Transmission Structure for Data Gathering under Distortion Constraints

Razvan Cristescu

We consider the joint optimization of sensor placement and transmission structure for data gathering, where a given number of nodes need to be placed in a field such that the sensed data can be recon structed at a sink within specified distortion bounds wh ...

Group communication based on standard interfaces

André Schiper, Matthias Wiesmann, Xavier Défago

While group communication system have been proposed for some time, they are still not used much in actual systems. We believe that one reason for this is the lack of standardisation of group communication system interfaces. The paper proposes an architectu ...

Dynamic Group Communication

André Schiper

Group communication is the basic infrastructure for implementing fault-tolerant replicated servers. While group communication is well understood in the context of static systems (in which all processes are created at the start of the computation), current ...

Towards JMS-Compliant Group Communication

André Schiper, Matthias Wiesmann, Stefan Pleisch, Arnas Kupsys

Group communication provides communication primitives with various semantics and their use greatly simplifies the development of highly available services. However, despite tremendous advances in research and numerous prototypes, group communication stays ...

Methods of multicriteria decision analysis within the road projects like an element of the sustainability

André-Gilles Dumont, Micaël Tille

The present communication is based on the research undertaken by the author and whose principal results are detailed in its thesis entitled « Choice of alternatives of road infrastructures : multicriteria methods » like on the prospects offered by this one ...

Gestures for Multi-Modal Interfaces: A Review

Sébastien Marcel

This document presents a review on gestures for multi-modal interfaces and focus on hand gestures. It first introduces the role that the gesture modality plays in human communication. It then describes different types of gestures. Finally, it gives an over ...

The VidTIMIT Database

This communication describes the multi-modal VidTIMIT database, which can be useful for research involving mono- or multi-modal speech recognition or person authentication. It is comprised of video and corresponding audio recordings of 43 volunteers, recit ...

Agent Communication Semantics for Open Environments: Issues and Challenges

Steven Nicolas Willmott

Explicit communication semantics are often considered essential for rich interaction between heterogeneous automated systems. While extensive work on semantic models has been carried out, much of this work remains to be tested in real open environments. Th ...

Coded Modulations Using Chaotic Systems Controlled by Small Perturbations

Martin Hasler, Thomas Schimming, Kumiko Oshima

Recently it has been observed that communications using chaos show best performance if the information production related to the chaos in the transmitter is controlled and used for the payload of the communication \cite{Schimming:Nolta:2002}. In the case o ...

The distributed Karhunen-Loeve transform

Martin Vetterli, Michael Christoph Gastpar, Pier Luigi Dragotti

The Karhunen-Loeve transform is a key element of many signal processing tasks, including classification and compression. In this paper, we consider distributed signal processing scenarios with limited communication between correlated sources, and we invest ...
