ORBi Open Repository and Bibliography (251,989 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.

4. Implementing and Comparing Stochastic and Robust Programming - Cuvelier, Thibaut
Traditional optimisation tools focus on deterministic problems: scheduling airline flight crews (with as few employees as possible while still meeting legal constraints, such as maximum working time), finding the shortest path in a graph (used by navigation systems to give directions, usually based on GPS signals), etc. However, this deterministic hypothesis sometimes yields useless solutions: actual parameters cannot always be known to full precision, one reason being their randomness. For example, when scheduling trucks for freight transportation, if there is unexpected congestion on the roads, the deadlines might not be met, the company might be required to financially compensate for this...

6. Carbon nanotube composites for broadband microwave absorbing materials - Saib, Aimad; Bednarz, Lukasz; Daussin, Raphaël; Bailly, Christian; Lou, Xudong; Thomassin, Jean-Michel; Pagnoulle, Christophe; Detrembleur, Christophe; Jérôme, Robert; Huynen, Isabelle
In this paper, we present a new shielding and absorbing composite based on carbon nanotubes (CNTs) dispersed inside a polymer dielectric material. The extremely high aspect ratio of CNTs and their remarkable conductive properties lead to good absorbing properties with very low concentrations. A broadband characterization technique is used to measure the microwave electrical properties of CNT composites. It is shown that a conduction level of 1 S/m is reached for only 0.35 weight % of a CNT, while, for a classical absorbing composite based on carbon black, 20% concentration is mandatory. The conductive properties are explained by a phenomenological...

17. Rankine cycle based waste heat recovery system applied to heavy duty vehicles: topological optimization and model based control - Grelet, Vincent
standards force the original engine manufacturers to search for innovative solutions in order to reduce oil consumption. As an important part of the energy contained in the primary carrier (the fuel) is lost to the ambient through heat, it seems convenient to recover a part of this thermal energy and to turn it into fuel consumption reduction. Thermodynamic bottoming cycle such as the Rankine cycle could be used to meet this objective. Its popular use throughout the world for electricity generation makes it a natural candidate for on-board implementation in vehicles. However, a certain number of hurdles are still present before the system can be efficiently applied...

18. Effects of acoustic degradations on cover song identification systems - Osmalsky, Julien; Embrechts, Jean-Jacques
Cover song identification systems deal with the problem of identifying different versions of an audio query in a reference database. Such systems involve the computation of pairwise similarity scores between a query and all the tracks of a database. The usual way of evaluating such systems is to use a set of audio queries, extract features from them, and compare them to other tracks in the database to report diverse statistics. Databases in such research are usually designed in a controlled environment, with relatively clean audio signals. However, in real life conditions, audio signals can be seriously modified due to acoustic degradations. For example, depending on the context, audio...
