Cave Genesis and its relationship to surface processes : investigations in the Siebenhengste region (BE, Switzerland)

Häuselmann, Philipp ; Monbaron, Michel (Dir.)

Thèse de doctorat : Université de Fribourg, 2002 ; Nr. 1383.

The Siebenhengste region is one of the most significant cave areas in the world. Its high density of cave passages that extend over 1500 m in altitude makes it a key site for the study of Alpine paleogeomorphology and paleoclimatology. The present thesis concentrates on St. Beatus Cave and Bärenschacht at the southern rim of the cave region. The tectonics, hydrogeology, speleogenesis,...

Tracing the decision maker

Schulte-Mecklenbeck, Michael ; Huber, Oswald (Dir.) ; Kühberger, Anton (Codir.)

Thèse de doctorat : Université de Fribourg, 2005.

This thesis focuses on two themes: a methodological and a decision making one. The methodological part introduces the development of a computerized information search tool. The program, called WebDiP (Web Decision Processes), enables the researcher to track participants while they are searching for information in a database. An experiment can be done either in the laboratory or on the Web. The...

Modeling the properties of open d-shell molecules with a multi-determinantal DFT

Rauzy, Cédrick ; Daul, Claude (Dir.)

Thèse de doctorat : Université de Fribourg, 2005 ; Nr. 1465.

Ligand field theory has been used along decades with success to describe ground and excited electronic states originating from dn transition metals complexes. Experimental chemists use such a theory to interpret spectra. On the opposite side, computational chemists can describe with good accuracy the ground states properties but models to calculate excited states properties are still being...

Phenotypic plasticity and genetic differentiation in ruderal and agricultural populations of the weed Senecio vulgaris L. : implications for its biological control

Leiss, Kirsten Anna ; Müller-Schärer, Heinz (Dir.) ; Schmid, Bernhard (Codir.)

Thèse de doctorat : Université de Fribourg, 2000 ; No 1304.

Phenotypic plasticity and genetic differentiation of the annual weed Senecio vulgaris L. from ruderal and agricultural habitats were investigated to evaluate the implications for its biological control with the rust fungus Puccinia lagenophorae Cooke using the system management approach. Weed demographic studies are a prerequisite to any weed control strategy. The population dynamics of S....

The high-resolution stratigraphic architecture and evolution of the Burdigalian carbonate-siliciclastic sedimentary systems of the Mut Basin, Turkey

Bassant, Philip ; Strasser, Andreas (Dir.)

Thèse de doctorat : Université de Fribourg, 1999 ; no 1256.

The factors influencing the production and deposition of carbonate sediments are known. These are namely accommodation variations (eustasy and tectonics), siliciclastic sediment input, environmental changes (temperature, salinity, trophic level), nature of the producing ecologies, and the hydrodynamic regime. However, the manner in which these factors integrate through time to produce the...

Interaction of Per and Cry genes in the mammalian circadian clock

Oster, Henrik ; Albrecht, Urs (Dir.)

Thèse de doctorat : Université de Fribourg, 2002 ; Nr. 1396.

To cope with the daily changes in their environment, in organisms, from cyanobacteria to humans, endogenous clocks have evolved that anticipate these changes and synchronize physiology and behavior accordingly. In mammals, the central circadian pacemaker is located in the suprachiasmatic nuclei (SCN) of the hypothalamus. From there subordinated cellular clocks in the peripheral organs are...

Automatic software configuration : a model for service provisioning in dynamic and heterogeneous environments

Schubiger-Banz, Simon ; Hisbrunner, Béat (Dir.)

Thèse de doctorat : Université de Fribourg, 2002 ; no 1393.

This dissertation addresses three fundamental problems, which have to be handled in application domains like ubiquitous computing and Web services. The three problems heterogeneity, static configuration, and dynamic configuration are not only considered to persist during the near future but to increase, as similar application domains will emerge. The heterogeneity problem is defined and examples...
