ORBi Open Repository and Bibliography (266.005 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. Developing system-level fragility functions for performance-based fire engineering of buildings

    Gernay, Thomas; Elhami Khorasani, Negar
    This research contributes to the current efforts for developing probabilistic methods in structural fire engineering (SFE) to foster the shift towards performance-based design in the field. A methodology is presented to assess the risk related to structural failure due to fire in multi-story buildings. At the core of this methodology is the concept of fragility functions, which allows quantifying in a systematic way the effects of the uncertainties in both demand and capacity parameters on the reliability level. The fragility functions, adopted here for the purpose of SFE, yield the conditional probability to reach predefined damage states as a function of...

  6. A Simple Method for Thermal Characterization of Low-Melting Temperature Phase Change Materials (PCMs)

    Salvador, Lucas; Hastanin, Juriy; Novello, Frédéric; Orléans, Adrien; Sente, Frédéric
    The successful implementation of a high-efficient latent heat storage system necessitates an appropriate experimental approach to investigate and quantify the variations of the Phase Change Material (PCM) thermal properties caused by its aging, as well as its potential demixing induced by cyclic freezing and melting. In this paper, we present a concept for the PCM characterization. The proposed method is relatively simple to be implemented. It consists of a cyclic cooling and melting of the PCM sample placed into a tube and monitoring its temperature evolution with a set of temperature sensors. In our work, the temperature evolution of the...

  7. Vers une société géolocalisée

    Hallot, Pierre
    A l’instar de la révolution induite par la disponibilité du temps pour chaque individu de la société, la possibilité de connaître sa position géographique conduit à de nouveaux challenges. Actuellement, il est possible de se géolocaliser à n’importe quel endroit du globe. Connaître sa position à l’intérieur d'un bâtiment, d'un centre commercial, voir au sein même d’un rayonnage n’est plus une utopie. Cette disponibilité de géolocalisation conduit d’une part à des changements importants dans la manière d’appréhender l’espace, et d’autre part, à la création de nouveaux services basé sur la connaissance de sa position en temps réel. A cours de...

  10. Contribution to the Characterization of Piston Expanders for Their Use in Small-scale Power Production Systems

    Oudkerk, Jean-François
    Piston expanders are well suited for small scale power generation (<50kW) using heat engines such as Ericsson engine or Organic Rankine Cycle (ORC) system. Both systems offer the possibility to use renewable energy sources and are increasingly considered in light of the economic and environmental context. This thesis aims at contributing to the knowledge and the development of piston expanders by presenting modeling, simulation and experimental investigations. Two types of piston engine models are proposed. The first type (denoted as “detailed”) describes the shaft angle (or time) evolution of the state of the fluid in the control volume limited by the...

  11. Modélisation, simulation et contrôle d’un cycle de Rankine organique en régime dynamique.

    Oudkerk, Jean-François
    Organic Rankine cycles (ORC) are thermodynamic cycles that allow the production of mechanical energy form low temperature heat source. Additionally, they are particularly suitable to small scale units. This work introduces the use of ORC to recover a variable flow rate and temperature heat source. As heat source’s characteristics are variables, it is judicious to be able to simulate the dynamic behavior of the system. The suggested model focuses mainly on dynamic behaviour of heat exchangers. A first model in steady state is primarily proposed and validated. The dynamic model is then described and also validated. Two controls strategies are...

  18. Probabilistic prediction of the quality factor of micro-resonator using a stochastic thermo-mechanical multi-scale approach

    Wu, Ling; Lucas, Vincent; Golinval, Jean-Claude; Paquay, Stéphane; Noels, Ludovic
    As the size of the device is only one or two orders of magnitude higher than the size of the grains, the structural properties, such as the thermo-elastic quality factor (Q), of micro-electro-mechanical systems (MEMS) made of poly-crystalline materials exhibit a scatter, due to the existing randomness in the grain size, grain orientation, surface roughness... In order to predict the probabilistic behavior of micro-resonators, the authors extend herein a previously developed stochastic 3-scale approach [1] to the case of thermoelastic damping [2]. In this method, stochastic volume elements (SVEs) [3] are defined by considering random grain orientations in a tessellation....
