ORBi Open Repository and Bibliography (192,859 recursos)
In may 2007, the ULg's Administrative Board (joined in June 2007 by the FUSAGx) decided to create an institutional repository and defined a strong institutional self-archiving policy to increase the visibility, accessibility and impact of the University's publications (Board's decision). This decision led to the official launch, in November 2008, of the ORBi platform including both the Academic Bibliography and the Institutional Repository of the Wallonia-Europe University Academy.

1. A LATERAL SENSOR FOR THE ALIGNMENT OF TWO FORMATION-FLYING - Roose, Stéphane; Stockman, Yvan
The coarse lateral sensor is a system able to measure the lateral position between two satellites. It bridges the gap between the alignment accuracy achieved with the radio frequency metrology, and the alignment accuracy required the highprecision optical metrology (fine-lateral and longitudinal sensor). The coarse lateral sensor developed at Centre Spatial de Liège (CSL) is a standalone unit. Once connected to an unregulated 28V power-supply, it delivers, the lateral position of a corner cube retro-reflector (within an angle of 10 arcdeg and from 25 to 250 m) and tracks this position at a rate of 10 Hz. The system is operational with the sun in its fieldof- view....

2. A Target Projector for Videogrammetry under Vacuum Conditions - Roose, Stéphane; Mazzoli, Alexandra; Barzin, Pascal; Jamotton, Pierre
Videogrammetry is a 3-dimensional co-ordinate measuring technique that (now) uses digital image capture as the recording method. Images are taken from at least two different locations and the light-rays from the camera to the measurement object are intersected by triangulation into 3D point coordinates. With a large number of images, the camera orientation and 3D point locations are accurately determined with the use of a full mathematical model (bundle adjustment). Adhesive targets are commonly used for point materialization. Those targets consist of a retro-reflective material, with an adhesive backing for sticking to the structure under investigation. A drawback of these types of targets is that they can lose their adhesion and shape during thermal...

12. Roughness evolution of sol-gel optical coatings by ion beam sputtering - Gailly, Patrick; Dubreuil, Olivier; Fleury-Frenette, Karl
The surface roughness evolution of two silica-based sol-gel materials under 650 eV argon ion beam sputtering has been investigated. The liquid sol-gel solutions had been applied on silicon substrates using the dip coating technique and then thermally cured to obtain solid thin films. Their thickness had then been controlled over the samples surface using spectroscopic ellipsometry. The surface roughness of the sol-gel films has been measured using both interferometric profilometry and atomic force microscopy at different sputtering depths. Roughness increases significantly faster with sputtering depth in sol-gel layers than on bulk fused silica. Interestingly, the sputtering rates of the sol-gel layers...

15. Model-Based Computation of Total Stressed Blood Volume from a Preload Reduction Experiment - Pironet, Antoine; Desaive, Thomas; Chase, J. Geoffrey; MORIMONT, Philippe; Dauby, Pierre
Total stressed blood volume is an important parameter for both doctors and engineers. From a medical point of view, it has been associated with the success or failure of fluid resuscitation therapy, which is a treatment for cardiac failure. From an engineering point of view, this parameter dictates the cardiovascular system's dynamic behavior. Current methods to determine this parameter involve repeated phases of circulatory arrests followed by fluid administration. In this work, a method is developed to compute stressed blood volume from preload reduction experiments. A simple six-chamber cardiovascular system model is used and its parameters are adjusted to pig...

17. CYANOBACTERIAL BLOOMS : TOXICITY, DIVERSITY, MODELLING AND MANAGEMENT - Descy, Jean-Pierre; Pirlot, S; Verniers, G; Viroux, L; Lara, Y; Wilmotte, Annick; Vyverman, W; Vanormelingen, P; Van Wichelen, J; Van Gremberghe, I; Triest, L; Peretyatko, A; Everbecq, Etienne; Codd, G. A.
The B-BLOOMS2 project aimed to deepen knowledge of cyanobacterial blooms in Belgium, improve the modelling for prediction and early-warning, develop operational monitoring structures and tools, and propose strategies to reduce the impact of cyanobacterial blooms. From a scientific point of view, the research programme focused on: - Collection of physical, chemical, biological and meteorological data on selected reference waterbodies plagued by toxic cyanobacterial blooms in Flanders, Brussels and Wallonia; - Identification and study of the toxigenic cyanobacteria present in the Belgian samples using molecular tools on samples and strains, including genetic diversity and factors regulating their population dynamics; - Measurement of the major cyanotoxins...

18. Design Thinking: l'approche empathique, clé de voûte de l'entreprise créative ? - Elsen, Catherine
La posture créative est à l’innovation ce que l’excellence opérationnelle est à l’entreprise: une démarche désormais incontournable. Et pourtant les plus sceptiques poussent nos communautés, avec raison, à poursuivre la réflexion: que reste-t-il à apprendre des méthodes créatives divergentes, comme le brainstorming par exemple ? Comment éviter à l’avenir la mise en œuvre répétitive et décontextualisée de recettes « toutes faites » qui dénaturent la créativité et nuisent à sa crédibilité ? Ces inquiétudes seront analysées par Catherine Elsen à la lumière du Design Thinking, cette approche méthodologique qui pourrait bien faire favorablement évoluer les représentations et accompagner chaque entreprise dans...
