A silvicultural decision support system (SDSS) has been developed for pure and even-aged larch stands (Larix sp.) in Walloon Region, where Larix seems to be a species with good prospects in a multifunctional management context. It main purposes are: (i) to predict the influence of silvicultural treatments on stand evolution and (ii) to help forest managers compare different scenarios according to preset goals. The SDSS comprises three modules designed for (i) larch growth prediction based on initial tree density, thinning regime and site index (scenarios building), (ii) assessment of a set of indicators describing scenarios and (iii) the comparison of scenarios according to appropriate calculated indicators (Multi-Criteria Decision Making or MCDM approach). Financial, technico-economic and ecological indicators are calculated in order to characterise wood production both qualitatively and quantitatively. One of them also tries to express a risk assessment (windthrow hazard). The MCDM method is based on partial aggregation (Electre III) and is used to compare scenarios according to the indicators. This SDSS is integrated in a user-friendly designed software “MGC_Larch” (Make Good Choice for Larch) that helps managers formulate, evaluate and compare different larch silvicultural scenarios according to their priority goals.

Un système de spectroscopie Auger basé sur un analyseur hémisphérique et balayage des énergies électroniques de 0 à 3000 eV a été construit et testé. Outre l'appareil de mesure proprement-dit, le développement a porté sur la construction d'une enceinte de travail, avec porte-échatillon et passages électriques pouvant supporter un vide extrêmement poussé (de l'ordre du nano-Pascal). L'appareil a été appliqué à l'étude d'échantillons de verre, afin de mieux comprendre les phénomènes de vieillissement du verre en atmosphère humide et l'adhérence de l'étain pour la fabrication de miroirs. L'originalité de la thèse est d'avoir pu identifier un certain nombre de conditions opératoires optimales, de manière à pouvoir travailler avec le verre, matériau isolant électrique. En effet, la spectroscopie des électrons Auger est basée sur le bombardement de l'échantillon par un faisceau d'électrons, qui s'accumulent dans le matériau isolant et font fortement dériver les pics de rétro-diffusion.

Conception of a method to promote extensive grassy headland’s establishment in permanent meadows of the Walloon Region. In accordance with agriculture evolution in Europe, the Walloon Region has emphasized the importance of buffer zones in agricultural parcels since many years. Consequently, one of the agri-environmental measures in force at the present time concerns extensive grassland strips settlement in agricultural parcels. Buffer zones preserve river quality, reduce soil erosion, diversify landscapes and promote biodiversity. With a Geographic Information System (GIS) based on the Integrated Administration and Control System (IACS) of the Walloon General Directorate of Agriculture, it is possible to detect parcel sections where farmers can introduce extensive strips in accordance with legal specifications in order to benefit of grants. Results of the new method are presented in a diagnostic table which includes an indicator expressing the total grantable strips length (in meters) at the exploitation scale. Its calculation is based on existing strips, surface and location of permanent meadow parcels. Results are completed with cartographic representation of settlement’s possibilities for each exploitation. These two complementary tools – diagnostic table and geographical map – can be very useful to manage agricultural exploitations. [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 water content is deduced from the measurement of the thermal diffusivity. The sensor allows a continuous monitoring of the water content. [less ▲]

The study of nationalism points to the notions of state which are underlying national affirmation. At the end of this century, when state intervention does not seem largely supported, how and to what extent are the notions of state and nation linked ? By using data from three surveys conducted in 1992, 1995 and 1996, in several Quebec universities, we present here various “response profiles” which students develop out of these same two notions. Data are actually analyzed with a multidimensional methods (correspondence analysis). Then, it is possible to point out series of similar responses to a number of questions. So, rather than simplifying phenomena, our research leads us to emphasize the complexity of individuals’ relations by taking into account the many worlds of reference relevant to questions that are addressed here. One of our major findings is the very weak link between the notion of state and nationalism. [less ▲]

The elastic behaviour of parabolic notch hinges submitted to the classical sollicitations of a beam is studied. For each sollicitation, an analytical solution is given first. Its asymptotic expression for very narrow hinges is then obtained and finally,, an approximate factor relating the exact solution to the asymptotic one is proposed. [less ▲]
