Stochastic individual-based models of adaptive dynamics and applications to cancer immunotherapy
(2017-03-24)
In this thesis stochastic individual-based models describing Darwinian evolution of asexual, competitive populations are studied. A specialization of these models is developed to describe tumor development under immunotherapy ...
Entwicklung einer Spurkammer für das Studium von Driftfeld-Kalibrationsmethoden
(2022-06-07)
Bei der Erforschung von Materie hat man sich in der Geschichte schrittweise, durch Beobachtungen und Modelle, an ihre untergeordneten Strukturen herangetastet. Aus heutiger Sicht sind Quarks und Gluonen, neben den Elektronen, ...
Discrete Riemannian Calculus and A Posteriori Error Control on Shape Spaces
(2018-01-04)
In this thesis, a novel discrete approximation of the curvature tensor on Riemannian manifolds is derived, efficient methods to interpolate and extrapolate images in the context of the time discrete metamorphosis model are ...
Modellierung und Simulation des effektiven Verhaltens von Grenzflächen in Metalllegierungen
(2007)
Die vorliegende Arbeit diskutiert die Modellierung und die numerische Simulation von Phasenübergängen bei der Ostwald-Reifung entmischter Metalllegierungen und in magnetischen Formgedächtnis-Materialien. Dabei werden die ...
Uniform estimates in one- and two-dimensional time-frequency analysis
(2019-02-22)
This thesis is concerned with two special cases of the singular Brascamp-Lieb inequality, namely, the trilinear forms corresponding to the one- and two-dimensional bilinear Hilbert transform. In this work we study the ...
Migration of interneuronal precursor cells in the developing cerebellum of mice: model-based cell tracking and simulation
(2010-12-10)
The navigation of precursor cells of inhibitory interneurons from their germinal zone inside the fourth ventricle through the white matter towards their final destination within the cerebellum's molecular layer is an ongoing ...
Multiscale Simulation of Polymeric Fluids using Sparse Grids
(2016-12-21)
The numerical simulation of non-Newtonian fluids is of high practical relevance since most complex fluids developed in the chemical industry are not correctly modeled by classical fluid mechanics. In this thesis, we implement ...
The Curve Graph and Surface Construction in S x R
(2011-01-13)
Suppose S is an oriented, compact surface with genus at least two. This thesis investigates the \homology curve complex" of S; a modification of the curve complex first studied by Harvey in which the verticies are required ......
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. ...
On discrete surfaces: Enumerative geometry, matrix models and universality classes via topological recursion
(2019-03-21)
The main objects under consideration in this thesis are called maps, a certain class of graphs embedded on surfaces. We approach our study of these objects from different perspectives, namely bijective combinatorics, matrix ...
