Algorithms for Circuit Sizing in VLSI Design
(2016-05-10)
One of the key problems in the physical design of computer chips, also known as integrated circuits, consists of choosing a physical layout for the logic gates and memory circuits (registers) on the chip. The layouts ...
Contributions to Stochastic Modelling of the Immune System
(2016-05-12)
During the past century, mathematical modelling of biological processes rapidly developed into a field of high scientific interest. The diversity of mathematical approaches and biological applications is large. Some key ...
On quotients of ω* and automorphisms of P(ω)/fin that preserve or invert the shift
(2016-05-30)
The first part of the dissertation concerns the space ω*:=βω\ω and its quotients. A 2002 result from Bella, Dow, Hart, Hrusak, van Mill and Ursino implies that homeomorphisms between 0-dimensional second-countable Hausdorff ...
Spektraläquivalente Vorkonditionierung lokaler Operatoren mittels H-Matrizen und das Landau-Lifschitz-Modell als Anwendung
(2013-03-25)
Diese Arbeit beschäftigt sich mit der optimalen Vorkonditionierung von Gleichungssystemen resultierend aus der finite Elemente Diskretisierung von elliptischen Differentialgleichung zweiter Ordnung. Anschließend wird ein ...
The fate of a recessive allele in a Mendelian diploid model
(2017-08-23)
The omnipresence of sexual reproduction in a highly competitive world is a fascinating phenomenon. Its evolution and maintenance is up to now not completely understood since it is known that sexual reproduction require ......
Numerical Methods in Shape Spaces and Optimal Branching Patterns
(2017-04-25)
The contribution of this thesis is twofold. The main part deals with numerical methods in the context of shape space analysis, where the shape space at hand is considered as a Riemannian manifold. In detail, we apply and ......
Geometrical Methods for the Analysis of Simulation Bundles
(2017-03-29)
Efficiently analyzing large amounts of high dimensional data derived from the simulation of industrial products is a challenge that is confronted in this thesis. For this purpose, simulations are considered as abstract ...
Mathematical Analysis and Modeling of Signaling Networks
(2017-11-24)
Mathematical models are in focus of modern systems biology and increasingly important to understand and manipulate complex biological systems. At the same time, new and improved techniques in metabolomics and proteomics ...
Rational global homotopy theory and geometric fixed points
(2017-12-20)
We use geometric fixed points to give a multiplicative algebraic model for rational global homotopy theory with respect to finite groups. It has infinite homological dimension and we study the formality of K-theory. ...
Stability of Stochastic Differential Equations with Jumps by the Coupling Method
(2017-10-06)
The topic of this thesis is the study of R^d-valued stochastic processes defined as solutions to stochastic differential equations (SDEs) driven by a noise with a jump component. Our main focus are SDEs driven by pure jump ...
