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.

Das Konzept der Argumentations-Systeme dient dem Zweck der Darstellung von insicherer oder unpräziser Information. Unsicherheit wird in Argumentations- Systemen durch sogenannte Annahmen dargestellt. Eine gegebene Hypothese kann dann in Abhängigkeit der Annahmen bewiesen oder verworfen werden. Hauptaufgabe des Annahmen-basierten Schliessens ist die Bestimmung von Argumenten welche eine gegebene...

Weak-coupling instabilities of two-dimensional lattice electrons

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

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

Das Problem wechselwirkender Elektronen in zwei Dimensionen ist spätestens seit der Entdeckung der Hoch-Temperatur-Supraleitung von grosser Aktualität und Gegenstand intensiver Forschungstätigkeit. In der vorliegenden Arbeit wird ein erweitertes Hubbard-Modell auf einem Quadratgitter untersucht. Obwohl man weiss, dass die Leitungselektronen in den Kupraten relativ stark miteinander...

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...
