Le nombre limité de données épidémiologiques sur la santé bucco-dentaire des enfants belges nous a conduits à réaliser une étude pilote dans ce domaine. L'objectif était de recenser un maximum d'informations sur la carie dentaire et ses facteurs de risque. L'enquête a été réalisée sous la forme d'un dépistage clinique chez des enfants âgés entre 6 et 12 ans et scolarisés dans deux établissements de la région liégeoise. [less ▲]

Faculties at the University of Liège, just like so many of their academic colleagues worldwide, have to write and orally present a syllabus for each of their courses every year. Although very demanding, this effort is clearly described by many authors as an important opportunity to make a decisive first impression and to favourably affect students’ attitude and perceptions toward a given course regarding their personal needs and motivation notably. Even if the hypothesis seem plausible and inspiring for practice at first sight, the likelihood of a given syllabus to actually impact those perfection in the right way still has to be experienced. So, for a syllabus whose qualities / characteristics seem to make it likely or not to impact positively or negatively learners’ perceptions of courses linked to their motivation and individual needs, will consistent effects be observed on the ones who have read / heard it? Among the students’ perceptions that an effective syllabus would be likely to positively impact according to the literature, some appear to correspond to the three determining factors of the motivational dynamics’ model from Roland Viau [1997]: the perception of controllability [Bain, 2004; Lang, 2006; Hudd, 2003], the perception of activities value [Wasley, 2008, Hammons & Shock, 1994; Johnson, 2006] and the perception of competency [Slattery & Carlson, 2005; Madson, Melchert, Whipp, 2004]. Other theoretical benefits of the syllabus on students’ attitude refer to the “consideration of what students need in order to be successful learners” [Hess & Whittington, 2003] or the support of “developmental needs of the students” [Haugen, 1998]. Here, items used to check learners’ perceptions and to observe if “the syllabus addresses the question of whether the class will meet student needs” [Birdsall, 1989] have been closely related to the levels of Abraham Maslow’s Hierarchy of Needs Chart. In 2008, within its mandatory program of pedagogical training for new faculties, the IFRES (Institute for Training and Research in Higher Education) has created a thematic seminar offering guidelines to promote syllabi aiming notably to motivate students and meet developmental needs. At the beginning of the following academic year, ten syllabi and introduction speeches - meant to Freshmen or Sophomores and designed by ten faculties who followed the seminar - were collected and recorded in order to be analyzed. Their likelihood to impact the targeted students’ perceptions was then rated according to criteria rigorously derived from literature. During the second class of the ten teachers, questionnaires were submitted to their 1300 First/Second-Year students in order to investigate the possible corollary impact of those transmitted pieces of information on their concerned perceptions. In order to measure hypothetical gains due to syllabi, couples of symmetrical pre and post items were included. Data collected from the students concerning their post perceptions and their answers about their reading / hearing or not of their respective syllabi /oral speeches are currently crossed. Chi squares are calculated to identify significant relationships between them, as well as correlations indexes. Afterwards, synoptic tables are produced to observe consistencies between ratings of teachers’ performances and students’ levels of declared perceptions. At this stage, it appears that variables regarding motivation are clearly independent for about 2/3 of the studied relations. Nevertheless, considering the cases where the X²test indicate links between the data, concrete consistencies can be observed between the ratings obtained from the content analysis of syllabi or speeches and the observed percentages of students declaring good perceptions. Besides, the comparison of the percentages of students declaring good perceptions before and after having received syllabi and speeches clearly indicate frequent consistencies with the syllabi’s ratings on the same variables. Looking at the impressive number of universities everywhere asking or urging their teachers to produce syllabi for each of their courses, it seems obvious that this task has become a classic in any faculty’s pedagogical practice. This generalization also seems to indicate a consensus on the fact that this effort make sense and can be useful, particularly for students. This research aims to objectify this usefulness in order to guide and promote professors’ reflection on effective syllabus - for instance in the context of a regulated training seminar -, especially since it is also considered to benefit as planning tool for faculties [Littlefield, 1999; Matejka & Kurke, 1994 ; Sinor & Kaplan], or as permanent record for promotions or program consistency [Parkes & Harris, 2002; Leibow, 2003 ; Seldin, 1998].

This paper presents new developments to link OptiView and a Discrete Event production Simulation (DES) software. The OptiView Software, is designed to maximize the number of ship blocks and ship sections produced in workshops during a certain time window. We decided to combine the strong points of both, the OptiView software and the DES simulation. Indeed, the production simulation is very effective for the modelling of the movement of the gantry crane while OptiView is very powerful for the allocation of blocks and optimization of the surface. This tool was developed to support planners to improve the space utilization and workshop productivity. The combination of both methods will deliver better results for lead time and cost. [less ▲]

Positioning is a fundamental issue in mobile robot applications that can be achieved in multiple ways. Among these methods, triangulation with active beacons is widely used, robust, accurate, and flexible. Our paper presents a new active beacon-based angle measurement system for indoor navigation using infrared signals. We propose a complete system for global positioning on a 2D plane based on the following parts: (1) a mirror, a lens, and a light guide, (2) a mini stepper motor and its controller, (3) an infrared receiver (TSOP7000), (4) a PIC microcontroller, and (5) three infrared beacons. The acquisition rate is 10 [Hz] and the accuracy is about 0.1 [degree]. The entire sensor is contained in a (8 X 8 X 8) [cm3] volume. The key innovation is the use of a cheap and simple infrared receiver as the main sensor for the angle measurement principle. The beacons too are simple cheap infrared LEDs. Furthermore, the system requires only one infrared communication channel, and no synchronization between the beacons and the robot is required. [less ▲]

The real-time interpretation of video scenes and human motion is a research field with a lot of applications. Awidely used pre-processing step is the background subtraction, which highlights silhouettes. In addition, example-based and learning-based approaches are attractive for the interpretation of complex scenes. But to be effective, such techniques need to be trained on samples of realistic human silhouettes. This paper presents a method to automatically build databases of artificial, realistic, and annotated human silhouettes. Our method, based on a 3D human avatar, allows to save additional data with the silhouettes, and to highlight the different body parts. These supplementary data may be application-driven. To help in evaluating the relevance of automatically generated databases, we suggest some practical solutions based on a visual signature of the databases. [less ▲]

Le bilan de masse de surface (BMS) de la calotte polaire Antarctique est une composante majeure de l’évolution du niveau des mers. Le modèle de circulation général LMDZ4 et la grande majorité des modèles atmosphériques utilisés dans l’IPCC-AR4 prévoient une augmentation du BMS en Antarctique au cours du siècle prochain, menée par une augmentation des précipitations neigeuses, qui contribuerait à une modération de l’élévation du niveau des mers. Les changements prévus sont particulièrement importants sur la zone côtière Antarctique, qui concentre la majorité des précipitations du continent. Il est donc crucial d’avoir une connaissance plus fine de l’évolution du BMS Antarctique, particulièrement en zone côtière. Les modèles actuels atteignent une résolution de 60 km à l’échelle de l’Antarctique pour des simulations longues (> 20 ans). L’objectif de ma thèse est d’estimer le BMS à une résolution inférieure à 15 km sur l’ensemble du continent, en désagrégeant les sorties des modèles de climat avec un modèle à temps de calcul réduit. La validation des modèles désagrégés est un point clé pour estimer la qualité des simulations futures. Or cette validation n’est pas aisée, du fait de l’impossibilité de mesurer directement les précipitations neigeuses et de la faible quantité de données d’accumulation à l’échelle du continent. Nous commencerons donc par une évaluation de la base de données Glacioclim-SAMBA et son utilisation pour valider différents modèles de climat en région côtière. Nous nous concentrerons ensuite sur la validation des modèles à l’échelle de l’Antarctique, en proposant une modification de la méthode utilisée par Arthern et al. (2006) pour fournir une climatologie du BMS à partir de données de terrain et de données satellite. Enfin, nous verrons le fonctionnement des modèles de désagrégation des précipitations et du bilan d’énergie en surface de la calotte polaire Antarctique. Je préciserai ma contribution au développement des modèles et présenterai des résultats préliminaires de désagrégation du BMS ainsi que les modifications que je prévoie d’apporter aux modèles.
