Approximation algorithms are motivated by the fact that for many important optimization problems we cannot hope to efficiently find an optimal solution (unless P=NP). Instead, we have to settle for second best — a solution that is close to being optimal. A natural question that arises is: how close to the optimal solution can one get with an efficient algorithm? The past two decades have...

Wireless sensor networks (WSNs) are a fast developing research area with many new exciting applications arising, ranging from micro climate and environmental monitoring through health and structural monitoring to interplanetary communications. At the same time researchers have invested a lot of time and effort into developing high performance energy efficient and reliable communication protocols...

L’étiologie des allodynies mécaniques est sujette à la controverse. Dans cette recherche, 25 allodynies mécaniques stastiques (AMS), traitées par rééducation sensitive (n = 23 patients), ont été étudiées topographiquement: les AMS cartographiées (allodynographies) rétrécissent en surface. Leur mode de disparition successif a été cartographié, ainsi que l’apparition de leur...

Thermische Kraftwerke: Wie kann die Wärme genutzt werden? Die Stromerzeugung wird künftig häufig durch thermische Kraftwerke sichergestellt,die einerseits mit fossiler Energie und andererseits mit erneuerbaren Energien betrieben werden. Unabhängig davon, inwiefern fossile Energiequellen durch erneuerbare Quellen abgelöst werden, bedingt die Verwertung der Wärme aus Erdwärme, Biomasse...

Software changes. Any long-lived software system has maintenance costs dominating its initial development costs as it is adapted to new or changing requirements. Systems on which such continuous changes are performed inevitably decay, making each maintenance task harder. This problem is not new: The software evolution research community has been tackling it for more than two decades. However,...

Nos régions alpines sont au coeur du château d’eau de l’Europe. Cependant, du fait d’un cloisonnement technique et administratif entre les communes, de grandes disparités sont à constater dans la problématique d’adduction d’eau potable. Certaines communes disposent de ressources en eau potable en quantité et en qualité alors que d’autres, voisines, doivent recourir à des...

Credal networks are probabilistic graphical models that extend Bayesian nets to deal with imprecision in probability, and can actually be regarded as sets of Bayesian nets. Credal nets appear to be powerful means to represent and deal with many important and challenging problems in uncertain reasoning. The counterpart of having more freedom in the modeling phase is an increased inferential...

Middleware-based database replication protocols require few or no changes in the database engine. As a consequence, they are more portable and flexible than kernel-based protocols, but have coarser-grain information about transaction access data, resulting in reduced concurrency and increased aborts. This paper proposes conflict-aware load-balancing techniques to increase the concurrency and...

A common opinion in the Requirements Traceability field is that solution design, i.e. the design of the application solutions, may be derived directly from requirements refinement; according to current industrial practices and to some specific experiences, this dissertation proposes a different thesis: the design process is not a fully rational and explicit sequence of actions; designers keep...
