La civilisation islamique joue un role efficace non seulement a enrichir la occidentale mais encore humaine. Son apport manifeste dans tous les domaines. En mettant l'accent sur tel role, nous pouvons dissiper le mythe d'exceptionnalisme selon lequel est meilleure et exceptionnel utilisant pour accuser l'islam par l'arriere, justifier racisme antimusulman domination de l'Occident quelques pays ...

« Etre avec et aller vers », telle est la définition minimale du verbe accompagner. Cette perspective fait de l’accompagnement une relation particulière qui repose sur valeur symbolique partage (Paul, 2009). Parler d’accompagnement doctoral marque donc un positionnement conceptuel fort. Quelles sont les implications éthiques d’une approche comment identifier? contribution aborde cette question ...

In this paper we discuss the meaning of sensitivity and its implications in CA behavior. A new shift-invariant metric is given. The metric topology induced by this metric is perfect but not compact. Moreover we prove that the new space is \suitable" for the study of the dynamical behavior of CA. In this context sensitivity assumes a stronger meaning than before (usually S Z is given the product...

In this paper, the problem of estimating the partial camera displacement from two images of a static object is studied. This scaled displacement is used to design a new vision-based control scheme, called 2D 1/2 visual servoing. It must be emphasized that motion and structure can be estimated without the a priori knowledge of a 3D model of the object, which increases the versatility and the app...

In this thesis work a complete study of the four quadrants coronagraph is presented This new coronagraph o ers performances of extremely large theorical rejection factor These performances open possibilities of exo planets detection around nearby stars The rst laboratory results gave an attenuation rate higher than on the central peak Thus I naturally studied all the possible uses of this coron...

The facilities provided by an office automation system must be efficiently usable by a wide variety of different user group_, each of which has definable characteristics with respect to skills, which should be exploited by,and expectations, which should be satisfied by, the user-system interface. There are three basic dialog formats which may be "_,combined to implement this interaction: menu, ...

In this paper we extend, by allowing rank 2 intersection types, the type assignment system for the detection and elimination of dead code in typed functional programs presented by Coppo et al Giannini and the rst author in the Static Analysis Symposium '96. The main application of this method is the optimization of programs extracted from proofs in logical frameworks, but it could be used as we...

Ambiguity in scene information, due to noisy measurements and uncertain object models, can be quantiied and actively used by an autonomous agent to eeciently gather new data and improve its information about the environment. In this work an information-based utility measure is used to derive from a learned classiication of shape models an eecient data collection strategy, speciically aimed at i...

We study the problem of eeciently evaluating transactions that automatically invoke the execution of (deferred) database triggers at the end of the transaction. In particular, we consider an important class of triggers which may express arbitrary integrity constraints and alerters. Their event part speciies data modiications, their condition part is an arbitrary database query, and their action...

Throughout history, nothing has killed more human beings than infectious diseases. Although, death rates from pandemics dropped globally by about 0.8 % per year, all the way through 20th century, number of new diseases like Sars, HIV and Covid-19 increased nearly fourfold over past century. In Africa, there were reported a total 4,522,489 confirmed COVID-19 cases 119,816 death, as 23 April 2021...
