Study of 110Cd using the (n, n'γ) reaction and 114Te using the (α, 2n) reaction

Corminboeuf, Frédéric ; Jolie, Jan (Dir.)

Thèse de doctorat : Université de Fribourg : 2000 ; Nr. 1326.

The study of nuclear structure is one of the research domains in nuclear physics which have known an important development. It has asked a great effort for the experimenters as well as the theoreticians to study in detail the nuclear many-body problem. In the framework of this thesis, we have tested several nuclear models for two nuclei: 110Cd and 114Te. This choice has not been made at random....

Argumentation systems and belief functions

Lehmann, Norbert ; Kohlas, Jürg (Dir.) ; Moral, Serafin (Codir.)

Thèse de doctorat : Université de Fribourg : 2001 ; 1340.

Uncertain knowledge can be represented in the framework of argumentation systems. In this framework, uncertainty is expressed using so-called assumptions. Depending on the setting of the assumptions, a given hypothesis of interest can be proved or falsified. The main goal of assumption-based reasoning is to determine the set of all supporting arguments for a given hypothesis. Such a supporting...

Weak-coupling instabilities of two-dimensional lattice electrons

Binz, Benedikt ; Baeriswyl, Dionys (Dir.) ; Douçot, Benoit (Codir.)

Thèse de doctorat : Université de Fribourg : 2002 ; 1374.

Interacting e1ectrons in two dimensions are of particular interest in relation to high-temperature superconductivity. In this thesis, I study a two-dimensional extended Hubbard model in the weak coupling limit. Quite generally, the electron gas is unstable towards a superconducting state even in the absence of phonons. However in the special case of a half-filled band, the Fermi surface is nested...

Content-based image retrieval using hand-drawn sketches and local features : a study on visual dissimilarity

Banfi, Folco ; Ingold, Rolf (Dir.)

Thèse de doctorat : Université de Fribourg : 2000 ; no 1312.

This thesis addresses the question of content-based image retrieval (CBIR) in heterogeneous databases. In an analysis of the existing CBIR tools that was done at the beginning of this work, we have shown that there was room for improvement in three key areas: query form, image and query representation, and computation of similarity. This analysis led us to studying the usability of a method for...

Locational Strategies of International Hotel Corporations in Eastern Central Europe

Johnson, Colin ; Dembinski, Paul (Dir.) ; Vanetti, Maurizio (Codir.)

Thèse de doctorat : Université de Fribourg : 2002.

This study investigated expansion strategies of international hotel operators in Eastern Central Europe. Due to the growing importance of services in economic development, there is an impressive body of knowledge on the process of internationalization and service industries. The last comprehensive academic study on internationalization and the hotel industry was undertaken at the beginning of the...
