Robert Killick-Kendrick est décédé le 22 octobre 2011 à Sumène, dans ce Pays cévenol où il avait choisi de se retirer après une longue vie de chercheur, initiée à l’âge de 17 ans au Département de biochimie du Ministère britannique de l’agriculture. Huit années au Nigeria, passées à étudier les trypanosomoses humaines et animales, devaient constituer le prologue d’une carrière consacrée à une p...

Visual Information Extraction (VIE) is a technique that enables users to perform information extraction from visual documents driven by the visual appearance and the spatial relations occurring among the elements in the document. In particular, the extractions are expressed through a query language similar to the well known SQL. To further reduce the human effort in the extraction task, in this...

Extracting knowledge without disclosing any individual or sensitive information is a new challenging problem for the data mining community. In this paper, we present a new algorithm PRIPSEP (privacy preserving sequential patterns) for the mining of sequential patterns from distributed databases while preserving privacy. We prove that our architecture and protocols employed by our algorithm are ...

LA TRANSPLANTATION D’ORGANES HUMAINS VITAUX SAUVE LA VIE de quelque 1500 Canadiens par année, ou l’améliore de façon spectaculaire. Ces interventions délicates, qui ne sont plus expérimentales, évitent aussi au système de soins de santé des millions de dollars de frais d’hospitalisation, de dialyse et autres. Or, malgré l’appui général de la population, le Canada enregistre un des taux les plus...

We consider numerical solutions of a class of nonlinear (nonstandard) Volterra integral equations. We first prove the existence and uniqueness of the solution of the Volterra integral equation in the context of the space of continuous funtions over a closed interval. We then use one point collocation methods and quadrature methods with a uniform mesh to construct solutions of the nonlinear VIE....

The time-oriented analysis of electronic patient records at a (neonatal) intensive care unit is a tedious and time-consuming task. The vast amount of data available makes it hard for the physician to recognize the essential changes over time. VIE-VISU is a data visualization system which uses multiples to present the change in the patient’s status over time in graphic form. Metaphor graphics is...

We derive and analyze two equivalent integral formulations for the time-harmonic electromagnetic scattering by a dielectric object. One is a volume integral equation (VIE) with a strongly singular kernel and the other one is a coupled surface-volume system of integral equations with weakly singular kernels. The analysis of the coupled system is based on standard Fredholm integral equations, and...
