ORBi Open Repository and Bibliography (301.662 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. A Simulator to Explore Tarification Designs for Distribution Networks

    Manuel de Villena Millan, Miguel; Gautier, Axel; Fonteneau, Raphaël; Ernst, Damien
    This paper introduces a computational tool to help assessing the impact of regulation policies within distribution networks in the deployment of distributed renewable electricity generation. This tool is a comprehensive multi-agent simulator capable of handling the interaction between the users of a distribution network and their distribution system operator. With this simulator, it is possible to address the different regulatory constraints encountered by distribution system operators, for any regulation policy. In the simulator, we model individual electricity consumers as rational agents, that may invest in optimised distributed renewable energy installations, if they are cost-efficient compared to the network tariff. By...

  6. Hollow Nanoparticles for Low Cost, High Activity and Durability for the Oxygen Reduction Reaction for Fuel Cell Applications

    Asset, Tristan
    This Ph.D. thesis investigates the mechanisms driving the formation, the enhanced activity for the oxygen reduction reaction (ORR) and the durability of porous hollow PtM/C nanoparticles (NPs) for proton ex-change membrane fuel cell (PEMFC) applications. The formation and growth of the NPs, synthesized by a ‘one-pot’ process, were discussed in the light of microscopic, operando X-ray and electron-based tech-niques, unveiling the different intermediate steps of the synthesis. The synthe-sis process was extended to different non-noble metals (M = Ni, Co, Cu, Zn and Fe) and to different carbon supports. The enhanced activity for the ORR resulted from (i) the contraction...

  14. Quelle politique énergétique en Belgique pour les 30 prochaines années ?

    Lilien, Jean-Louis
    L’évolution vers les énergies renouvelables (éoliennes et panneaux photovoltaïques) paraît incontournable. La cogénération (électricité et chaleur) aussi. Sans doute faut-il faire encore des progrès dans le stockage de l’énergie et, peut-être, dans l’utilisation de l’hydrogène. Hélas la variabilité du climat ne génère pas une production constante d’énergie. Notre proposons dès lors une solution basée sur une solidarité européenne (au sens large) et une souplesse d’utilisation du réseau d’énergie électrique. Tout en prônant un changement radical de paradigme : notre consommation doit s’adapter à la production et non l’inverse.

  16. Energy: the clash of nations

    Ernst, Damien
    Le monde de l'énergie est en guerre. C'est une guerre qui est menée sur de nombreux fronts, du Texas à l'Arabie saoudite, des salons feutrés de l'ONU et de l'organisation mondiale du commerce aux conseils d'administration des majors du pétrole, des laboratoires chinois en panneaux photovoltaïques aux champs éoliens de la mer du Nord. Dans ce tumulte guerrier, chaque nation essaie de défendre ses propres intérêts, d'avancer ses pions de la manière la plus intelligente possible, sachant très bien qu'une énergie abondante et bon marché est une des clés d'une économie puissante. Au cours de ce cours-conférence, le Prof. Ernst décodera...

  17. Nonlinear identification and control of Organic Rankine Cycle systems using sparse polynomial models

  18. Shallow geothermal energy: effect of in-situ conditions on borehole heat exchanger design and performance

    Radioti, Georgia
    The in-situ conditions are critical for the performance of Borehole Heat Exchangers (BHEs). However, in practice they are often not adequately considered, overwhelming the potential of these systems. This thesis focuses on the accurate estimation of the in-situ characteristics and on their influence on the design and the behaviour of BHEs based on an in-situ study of an heterogeneous bedrock in a semi-urban environment (campus of the University of Liege, Liege, Belgium). The experimental site consists of four double-U BHEs, of about 100 m long, installed over a surface area of 32 m² and equipped with fiber optic cables. Several...

  19. Dynamic modeling and control strategies analysis of a novel small CSP biomass plant for cogeneration applications in building

    Desideri, Adriano; Amicabile, Simone; Alberti, Fabrizio; Vitali-Nari, Silvio; Quoilin, Sylvain; Crema, Luigi; Lemort, Vincent
    A concentrated solar power (CSP) biomass combined heat and power (CHP) system based on organic Rankine cycle (ORC) technology developed in the framework of the EU founded BRICKER project is presented. The CHP system coupled with heat recovery ventilation technology and novel insulation material has the aim of reducing the energy consumption of existing building by up to 50%. A simplified approach to implement a dynamic model of the CHP system is proposed. The model is firstly used to investigate the performances of the CHP system control logic under extreme working condition. Secondly, the effectiveness in ensuring safe working conditions...
