ORBi Open Repository and Bibliography (269.533 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.

  18. A Bilevel Design and Pricing Model for an Intermodal Service Network

    Tawfik, Christine Maher Fouad; Limbourg, Sabine
    This work addresses the problem of jointly designing and pricing intermodal freight services during a medium-term planning horizon. Given the innate hierarchy in the problem, a bilevel program is considered where, at the upper level, an intermodal service provider seeks to maximize his profit through selecting the frequencies of his services and their associated prices, while at the lower level, target shipper firms choose to send their demands among the offered intermodal itineraries and the always available trucking competition.

  19. Early detection of university students in potential difficulty

    Hoffait, Anne-Sophie; Schyns, Michael

  20. Balanced words and related concepts: applications and complexity issues

    Crama, Yves
    In this talk, I present a few results and several questions about "regular" sequences of integers and related concepts, such as balanced words, partitions and covers of the integers by arithmetic sequences. Such concepts have been investigated in pure mathematics, but also naturally arise in a variety of application fields such as production planning, political science, or queueing theory. I briefly present some of these applications and explain how they motivate seemingly new questions relating, for instance, to the algorithmic complexity of regular partitions, or to the structure of balanced words. The presentation is based on joint work with Nadia Brauner and Vincent Jost (Grenoble).
