reliability investigation has always been one of the most important issues in power systems planning. the outages rate in power system reflects the fact that more attentions should be paid on reliability indices to supply consumers with uninterrupted power. using reliability indices in economic dispatch problem may lead to the system load demand with high reliability and low probability of powe...

This paper presents a description of the concepts and func-tionalities of the DOSMOS-Trace monitoring tool. The designing choices lead us to introduce the concepts of Event Manager Processes and Meta-Objects. It allows to keep a good scalability of the system but also to get a low intrusive monitoring tool.

Convex hull of some given points is the intersection of all convex sets containing them. It is used as primary structure in many other problems in computational geometry and other areas like image processing, model identification, geographical data systems, and triangular computation of a set of points and so on. Computing the convex hull of a set of point is one of the most fundamental and imp...

Minimax location problems have rece ived considerable attention in the literature as models for locating fac ilities tha t are to provide emerge ncy or convenient service to a set of ex isting facilities. In most of these problems the re is given a set of ex isting facilities whose locations are represented as points in some space, and new fac ility locations are also to be spec ified as points...

CSCW systems provide computer support to facilitate cooperation between users. In this paper we propose an approach for the formal speciication of func-tionality requirements and conndentiality security requirements of a CSCW application. These requirements give rise to safety and conndentiality properties that a CSCW system, supporting the application, should uphold. The speciication technique...

This development proves Yoneda's lemma and aims to be readable by humans. It only defines what is needed for the lemma: categories, func-tors and natural transformations. Limits, adjunctions and other important concepts are not included. There is no explanation or discussion in this document. See [O'K04] for this and a survey of category theory formalisations.

‎We extend the notion of approximately multiplicative to approximately n-multiplicative maps between locally multiplicatively convex algebras and study some properties of these maps‎. ‎‎W‎e prove that every approximately n-multiplicative linear functional on a functionally continuous locally multiplicatively convex algebra is continuous‎. ‎We also study the relationship between approximately mu...

The present knowledge of the structure of the photon is presented based on results obtained by measurements of photon structure functions at ee collider. Results are presented both for the QED structure of the photon as well as for the hadronic structure, where the data are also compared to recent parametrisations of the hadronic structure function F γ 2 (x, Q ). Prospects of future photon stru...

This paper deals with density and regression estimation problems for functional data. Using wavelet bases for Hilbert spaces of functions, we develop a new adaptive procedure based on wavelet thresholding. We provide theoretical results on its asymptotic performances.
