GIS (Geographical Information Systems) bring an ever increasing range of solutions to decision makers seeking ever more accurate situational awareness in the issues they are facing. In particular, a GIS can provide a broad range of visual information resulting from computations that may be complex. These require to develop and implement efficient algorithms because of the massive amount of computations or data that are induced by the geographical nature of the processed data. The Urban and Rural Planning and Study Lab of University of Liege seeks to compute accessibility profiles for so-called "slow transport modes" in the Walloon Region. In this context, a relevant issue of computation of a socio-economical index based on spatial and population data is considered. The objective of this work is to modelize a problem of computation accessibility index, then solve it. The central part consists of the developement of a consistent and efficient algorithm chain to compute optimal shortest paths in geographical zones by avoiding barriers. The integration of the involved algorithms as well as the exploitation of intermediary results are fundemental aspects of the proposed solution. Two variants of the problem are modelized: DLOSP (Discrete Line-Of-Sight Paths, that does not take barriers into account) and DGSP (Discrete Geodesic Shortest Paths, that takes barriers into account). The detection and indexation of the barrieres, the refitting of the considered search space, the optimization of visibility requests and the computation of shortest paths constitute the main steps of the proposed algorithm chain. A distributed computing setup, naturally stemming from the structure of the problem itself, is briefly presented. [less ▲]

The poplar wood has been known and used for a very long time. However, it has been systematically studied only since the end of the second world war, probably because of its reduced presence in the forests. An intuitive use of the poplar existed already among our ancestors but the study of its macro- and microscopic properties has directed it to more specific uses. The comprehension of its physical and mechanical properties led to a better knowledge of its behaviour during the various phases of transformation and helped to forecast its evolution when used, taking into account its natural longevity and the eventual presence of defects appearing on the trees and in the wood. In current poplar cultivation, all these characteristics must be considered to fix the criteria of selection taking into account the quality of the wood and its capability for transformation. The clonal production of poplars offers the transformation industry a raw material relatively homogenous in terms of technological properties, form and dimension. Nevertheless, each cultivar can differ in one or several of its characteristics. [less ▲]

Este trabajo intenta desde una de las múltiples formas posibles abordar el estudio del patrimonio cultural. El primero de sus propósitos es presentar un análisis jurídico sobre el desarrollo evolutivo del concepto, su significado, los bienes y valores que comprende y su funcionalidad como crisol de identidades, dentro del marco normativo de la jurisdicción colombiana y el correspondiente régimen que somete el acervo cultural de la nación. El segundo propósito es plantear el pluralismo como principio fundamental que orienta y describe la acción del Estado Social de Derecho hacia el reconocimiento efectivo de las diversidades que conforman el pueblo colombiano. Se intenta demostrar, que la integración nacional sólo se logra cimentando la identidad cultural sobre el diálogo intercultural y la disposición abierta a la interacción con otras culturas dentro y más allá del ámbito Estatal.
