This report presents an analytical approach leading to a prediction of the form errors arising when turning a bar, in the three classical fixture configurations. This study consists in determing the radial displacement at the tool end, due to the cutting forces. This displacement, will be retreived with the opposite sign, as a diameter error. Traditional analyses only consider the passive component of the cutting force. Here, the effect of the feed force is also considered. [less ▲]

Le rapport analyse les résultats d'une enquête portant sur la perception du vieillissement, de son impact et des politiques publiques les mieux à même de les résoudre. Le rapport montre la difficulté qu'il y a à défendre une politique de précaution face au vieillissement, l'opinion n'étant pas prête à accepter facilement des arbitrages entre pensions, âge de la retraite et montant des cotisations. Les personnes âgées sont cependant perçues comme une catégorie particulièrement légitime pour l'action publique. [less ▲]

In the frame of a "FIRST" project initiated by the Walloon Region, the research group developed a porous sensor able to measure the temperature and the water content of the soil by a thermal procedure.

The discretization errors of finite element approximations are examined in an abstract frame which is totally indepedent of the way of obtention of the solution. It is found that the error may be decomposed in an equilibrium error and a compatibility error, which may be combined as orthogonal vectors. Both errors admit upper and lower bounds which may be computed in a post-treatment scheme. [less ▲]

In this report, the theory of constrained elliptical problems is presented. Two classes of methods are used to solve such problems, which are the dualization and the penalty method. In the first one, use is made of Lagrange multipliers. The justification of this method has been given by Brezzi in 1974. This theory is presented in the present report by a particularly simple way, where use is made of elementary hilbertian geometry. Our step, which consists in building the solution, emphasizes the natural character of Brezzi's conditions. Extending this analysis, it was rational to also examine the penalty method, which is often preferred because its simpler implementation. It is shown that the convergence of this method necessitate some hypotheses which are in most cases equivalent to Brezzi's conditions. [less ▲]

Vis-a-vis the crisis of energy, the administrations and the public tertiary sector did not remain inactive in Wallonia. On the contrary, of many profets relating to the Rational Use of Energy (RUE) were conceived and realized by persons in charge who took in heart an improvement of their energy situation. The report/ratio which reports the history of some of these projects concluded by dynamic actors, who were able to include/understand their energy problems, there to distinguish ways of possible improvements and to give them life. The objective of this booklet is not to draw up the exhaustive list of these projects, but rather to quote examples of actions RUE conceived and carried out in the respect of their context. [less ▲]

Tailor's results on machining optimization always assume that the power of the machine tool is not a limitation. However, this not necessarily true, specially in the case of rough machining, where Taylorian optima are out of the power range of the machine. In this paper, an algorithm is proposed, where the machine capacity is the first consideration. The obtained result is then corrected in view of the tool life. [less ▲]

Local discretization errors are commonly done by inspecting local equilibrium errors. The difficulty lies in the fact that there is not, in general, a local convergence of equilibrium. Our point of view is that desequilibrium has to be considered in its natural frame, which is the dual space. In other word, desequilibrium has to be measured by the work that it is able to produce. Such quasi-local error measures are presented. [less ▲]

Accelerated wear tests of tools are used from the pioneering works of brandsma in 1936. But their justification is often somewhat intuitive. A formalized description of these test is presented, based upon an analysis of the conditions of validity of the cumulative damage principle. This gives the basis for a comparison between proposed procedures. It is found that some of them make use of stronger hypotheses and are thus of less theoretical value. [less ▲]

La morphologie mathématique englobe différentes techniques de filtrage aussi variées qu'originales. Parmi l'imposante panoplie des filtres se distinguent ceux qui sont nés de la morphologie à seuillage, encore appelée morphologie floue, très en vogue à l'heure actuelle. Ce document s'inscrit dans ce courant. Nous y définissons le concept central d'érosion partielle, simple transcription d'une opération déjà connue, pour l'étendre ensuite aux notions de dilatation, d'ouverture et de fermeture partielles. À l'inverse des développements récents en ce domaine, c'est l'aspect géométrique qui y tient le haut du pavé; les opérations partielles se conçoivent comme des interactions entre objets et non en termes de lois de probabilité. Elles conduisent à une série de procédés de lissage des contours d'images binaires gérés par un seuil unique et une famille d'éléménts structurants adaptés à l'application. Des techniques similaires sont évoquées pour des images en niveaux de gris. Nous introduisons ensuite le nouveau concept de polymorphisme d'un point. Ce dernier indique pour chaque point le nombre d'éléments structurants qui contiennent ce point. C'est par son entremise que pourront s'appliquer des procédés d'optimisation de filtrage puisqu'il fournit une mesure analytique. [less ▲]
