Gaussian linear information arises in many real-world models of the natural and social sciences. The Gaussian distribution has turned out to appropriately represent uncertainty in many linear models. The main goal of this thesis is to describe and to compare different algebras of Gaussian linear information: Corresponding elements and operations in the various algebras are revealed and the...

Die vorliegende kumulative Dissertation handelt von Alterspolitik in Schweizer Gemeinden, im spezifischen von deren Akteure, Funktionsweisen, Planungsvorhaben und politische Prozesse. Im Kontext der demographischen Alterung werden Fragen, um die sozialen und wirtschaftlichen Konsequenzen einer alternden Gesellschaft und der politischen Handhabung betroffener Themen, aktuell. In dieser...

Deep landslides (> 10 m) are generally characterized by phases of acceleration alternating with periods of lull, but most often lack real stabilization. Due to the continuous movement, it is difcult to evaluate the evolution of the activity. Therefore, a new methodology has been developed in order to precisely identify the sub-recent (20th century) and present evolution of deep landslide...

Many neurons and axons are eliminated during the development of the nervous system. These cells and their connections are thus overproduced, and the organism has to destroy the surplus in order to function correctly. A major mechanism responsible for this elimination appears to be competition between cells for a substance necessary for their survival. To examine this hypothesis, the present work...

In response to infection by pathogens, plants deploy various and complex defense mechanisms. Resistance can be expressed locally and systemically, depending on the nature of the inducing stimulus. For instance, after infection by a necrotizing pathogen, resistance develops throughout the plants, in tissues distant from the initial site of infection. This form of resistance, called systemic...

After injury to the adult central nervous system (CNS), permanent deficits remain to a large part due to limited cell renewal, axonal regeneration and reestablishment of functional connectivity. Evidence indicate that the lack of axonal regeneration is partly due to the myelin-associated inhibitory factor Nogo-A. A therapeutical strategy to overcome this inhibition is to prevent the neurite...

This thesis is a collection of properties and applications of linear barycentric rational interpolation, mainly with the weights presented by Floater and Hormann in 2007. We are motivated by the counterintuitive and provable impossibility of constructing from equispaced data an approximation scheme that converges very rapidly to the approximated function and is simultaneously computationally...
