A current challenge in system biology is to infer the regulation network of a family of pgenes from a n-sample of microarrays, with n (much) smaller than p. Gaussian graphicalmodels are simple models to describe these regulation networks. We propose a procedurethat performs Gaussian graph estimation by model selection. We introduce a collection ofcandidate graphs and then select...

Complex organization is found in many biological systems. For example, biopolymers could possess very hierarchic structure, which provides their functional peculiarity. Understating such complex organization allows to describe biological phenomena and predict molecule functions. Besides, we can try to characterize the specific phenomenon by some probabilistic quantities (variances, means, etc),...

Phase change materials combine a pronounced contrast in resistivity and reflectivity between their disordered amorphous and ordered crystalline state with very fast crystallization kinetics. Typical phase-change alloys are composed out of the elements germanium, antimony and tellurium. Due to the exceptional combination of properties phase-change materials find already broad application in non-...

Internet has led to a fundamental increase of information that is available to its users over the latest years. The users want to express their needs by simple means, such as queries and they want their queries to be evaluated without caring where the data are placed or how the queries are optimized. The work presented in this thesis contributes to the goal of declarative and efficient manageme...
