The documentation of the cultural heritage is a concern since 1885, with the first application of photogrammetry techniques by Albrecht Meydenbauer. In 1987, The International Council of Monuments and sites has recommended the creation of photogrammetry records of monuments and archaeological sites. Since then, the close range photogrammetry has been the most used technique to survey cultural heritage. This technique has become faster and more accessible with the advancement of digital cameras. Despite the recommendations of International Council of Monuments and sites, the advent of new technologies and the importance of a quality evaluation and documentation, there are few studies with a rigorous analysis of the requirements for the cultural heritage documentation, with focus on the geometry of the models generated by digital photogrammetry process. The aim of this work is to propose discussions and analysis of requirements for the evaluation of planimetric quality of photogrammetric projects applied to the cultural heritage documentation.

When one wants to compare the homogeneity of a characteristic in several popula- tions that have di erent means, the advocated statistic is the univariate coe cient of variation. However, in the multivariate setting, comparing marginal coe cients may be inconclusive. Therefore, several extensions that summarize multivariate relative dispersion in one single in- dex have been proposed in the literature (see Albert & Zhang, 2010, for a review). In this poster, focus is on a particular extension, due to Voinov & Nikulin (1996), based on the Mahalanobis distance between the mean and the origin of the design space. Some arguments are outlined for justifying this choice. Then, properties of its sample version under elliptical symmetry are discussed. Under normality, this estimator is shown to be biased at nite samples. In order to overcome this drawback, two bias corrections are proposed. Moreover, the empirical estimator also su ers from a lack of robustness, which is illustrated by means of in uence functions. A robust counterpart based on the Minimum Covariance Determinant estimator is advocated. [less ▲]

The effects of urban sprawl have been well documented, particularly regarding energy consumption. Suburban neighbourhoods are known to be energy inefficient and urban sprawl is considered as a major issue for sustainable development. To improve the energy efficiency of existing suburban urban fabrics is a major challenge that must be addressed to favour a sustainability transition of our built environment. In this context, this paper aims at investigating several scenarios that could be developed to improve the sustainability of existing suburban neighbourhoods: three main types of scenarios (building insulation, density, and urban form) and twelve sub-scenarios, which are focused on the possible evolution of the existing suburban building stocks, are proposed. Quantitative methods developed in previous research are used to assess and compare building and transportation energy consumption of a representative suburban case study. This application aims at investigating two main research questions: (1) "how to intervene in suburban neighbourhoods?" and (2) «where to intervene?" The main results of this application, which are focused on energy efficiency, are then studied in a larger framework to highlight their opportunities and constraints. The main findings of the paper are that, beyond the traditional polarisation of the debates on the energy efficiency of our built environment between the “compact” and the “sprawled” city, a new pragmatic paradigm, which is focused on the smooth densification of existing suburban neighbourhoods, can make them evolve towards greater sustainability.

The constraint of time-integrated zero area on the laser field is a fundamental requirement, both theoretically and experimentally, in the control of molecular dynamics. By using techniques of local and optimal control theory, we show how to enforce this constraint in two benchmark control problems, namely, molecular orientation and photofragmentation. The origin and the physical implications for the dynamics of this zero-area control field are discussed. [less ▲]

Cet exposé décrit les stratégies industrielles de valorisation des matières premières végétales en Région Wallonne et les différences par rapport aux modèles européens et internationaux existants. Les matières premières disponibles pour le bioraffinage de 1ère et 2ème générations sont listées sur base des données accumulées par les équipes de Gembloux Agro-Bio Tech. Les avantages et limitations de ces matières premières sont décrits. Les technologies de conversion commercialisables sont proposées en fonction des contraintes socio-économiques de la Wallonie: bioraffineries autonomes, intégrées, etc. Divers exemples de réalisations commerciales ou en prototypes sont proposés, de même que certains projets de R&D dans ce domaine.

Si le Moyen Âge peut sembler, de prime abord, une source d’inspiration particulièrement prolifique pour le jeu vidéo, c’est moins en tant que période historique qu’en tant que réservoir d’un imaginaire fantastique qu’il influence ce dernier. Cette influence remonte aux premières heures de l’histoire du médium : les jeux d’aventure textuels, par exemple, à la suite de l’œuvre initiatrice Adventure (William Crowther et Don Woods, 1977), prenaient généralement place dans un univers médiéval-fantastique largement inspiré de la licence Donjons et Dragons. La tendance récurrente à user d’un tel cadre thématique s’est ensuite maintenue sans discontinuer, accompagnant les évolutions du médium vidéoludique, comme en témoignent le nombre de jeux de rôle ou de jeux massivement multijoueurs qui, aujourd’hui encore, prennent place dans ce type d’univers. Pour ceux qui souhaiteraient s’imprégner de cette époque fascinante – tant pour son histoire que pour l’imaginaire qui lui est associé – nous avons sélectionné quelques œuvres à parcourir. [less ▲]
