First we study some properties of the modular group algebra Fpr [G] where G is the additive group of a Galois ring of characteristic pr and Fpr is the field of p r elements. Secondly a description of the Generalized Reed-Muller codes over Fpr in Fpr [G] is presented.

To obtain maximum unobtrusiveness with sensors for monitoring health parameters on the human body, two technical solutions are combined. First we propose contactless sensors for capacitive electromyography measurements. Secondly, the sensors are integrated into textile, so complete fusion with a wearable garment is enabled. We are presenting the first successful measurements with such sensors. ...

This report presents the approach of stochastic recursive equations (SRE) for the modeling and performance analysis of parallel systems. The aim of the paper is twofold. Firstly, we show how performance measures of many parallel systems can be adequately described and obtained using stochastic recursive equations. Secondly, we give an assesment on the capability of the SRE approach.

Economists agree that governance is one of the critical factors explaining the divergence in performance across developing countries. The differences of view between economists regarding governance are to do first, with the types of state capacities that constitute the critical governance capacities necessary for the acceleration of development and secondly, with the importance of governance re...

We present some improvements of a previous environment mapping work. Firstly, we relax a previous restriction about the environment orthogonality. And secondly, we increase the environment coverage by extending occupancy information in the map. Finally, some results show how that extension process yields to safer paths when extended maps are used for planning.

In this paper, we present a third-order Newton-type method to solve systems of nonlinear equations. In the first we present theoretical preliminaries of the method. Secondly, we solve some systems of nonlinear equations. All test problems show the third-order convergence of our method. 2006 Elsevier Inc. All rights reserved.

The Double Sine-Gordon (DSG) model has been often used for describing anisotropic spin chains. We firstly present classical transfer matrix calculations of thermodynamic quantities. Secondly, the effects of the quantum fluctuations are taken into account by means of an effective potential, which was successfully used for SG models.

Exact bounds for the positions of the branch points for cyclic coverings of the p-adic projective line by Mumford curves are calculated in two ways. Firstly, by using Fumiharu Kato’s ∗-trees, and secondly by giving explicit matrix representations of the Schottky groups corresponding to the Mumford curves above the projective line through combinatorial group theory.

Data exchanges between Web services engaged in a composition raise several heterogeneities. In this paper, we address the problem of data cardinality heterogeneity in a composition. Firstly, we build a theoretical framework to describe different aspects of Web services that relate to data cardinality, and secondly, we solve this problem by developing a solution for cardinality mediation based o...

Group classification rules extraction is an important task in pattern recognition. In this paper, we proposed a classification rules extraction algorithm base on fish swarm optimization. There are two main works in this article: firstly, fish swarm optimization is introduced. Secondly, a classification rules extraction algorithm is proposed. The proposed algorithm provides a good practicability...
