Nucleic acid sensing in CD4 T cells during HIV-1 and other viral infections
(2021-10-15)Viruses are small intracellular parasites and use the host cell’s biosynthesis machinery to replicate and spread. Therefore, viral particles incorporate structures that are similar to the ones that naturally occur within ... -
Nucleon-nucleon scattering process in Lattice Chiral Effective Field Theory approach up to next-to-next-to-next-to-leading order
(2018-04-23)We carry out a comprehensive analysis of the neutron-proton interaction up to the third order in the scheme of chiral effective field theory on the lattice. The complete two-pion exchange potential is taken into account ... -
Numerical Approximation of Optimal Microstructures in Elastic Shape Optimization
(2023-06-15)We develop and analyze a numerical two-scale optimization scheme for structural shape optimization. Whenever cost functionals, such as the elastic energy, are subject to minimization, while meeting a constraint on the ... -
Numerical calculation of automorphic functions for finite index subgroups of triangle groups
(2015-08-20)We present a new method to calculate automorphic functions for finite index subgroups of triangle groups. Since automorphic functions are holomorphic, it is well known that the real and the imaginary part are both harmonic. ... -
Numerical investigations of heat and mass transport in fractured porous rock masses
(2019-01-08)Fluid flow processes in the subsurface are accompanied by heat and mass transport with several important feedbacks including reactive flow, and precipitation/dissolution processes. Heat and mass transport through fractured ... -
Numerical Methods for a Reduced Model in Thin-Film Micromagnetics
(2008)We address the conformal finite element approximation to a reduced 2-d model arising in thin-film micromagnetics. The model was derived by DeSimone, Kohn, Müller, and Otto for a thin-film ferromagnetic element under an ...

Numerical Methods for Optimal Transport and Elastic Shape Optimization
(2019-12-06)In this thesis, we consider a novel unbalanced optimal transport model incorporating singular sources, we develop a numerical computation scheme for an optimal transport distance on graphs, we propose a simultaneous elastic ... -
Numerical Methods for Uncertainty Quantification in Gas Network Simulation
(2018-09-26)When modeling the gas flow through a network, some elements such as pressure control valves can cause kinks in the solution. In this thesis we modify the method of simplex stochastic collocation such that it is applicable ... -
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 ... -
Numerical methods in stochastic and two-scale shape optimization
(2018-04-26)In this thesis, three different models of elastic shape optimization are described. All models use phase fields to describe the elastic shapes and regularize the interface length on some level or scale to control fine-scale ... -
Numerical modeling of electromagnetic coupling effects for phase correction in borehole EIT measurements
(2017-04-25)Spectral Electrical Impedance Tomography (EIT) allows obtaining images of the complex electrical conductivity for a broad frequency range (mHz to kHz). It has recently received increased interest in the field of near-surface ... -
Numerical renormalization group studies in complex quantum impurity systems
(2006)In this thesis we summarize several theoretical studies in the context of quantum impurity systems. We implement the numerical renormalization group (NRG) technique as a powerful method for the solution of the Kondo and ... -
Numerical Renormalization Group Studies of the Partially Broken SU(3) Kondo Model
(2013-05-29)The two-channel Kondo (2CK) effect with its exotic ground state properties has remained difficult to realize in physical systems. At low energies, a quantum impurity with orbital degree of freedom, like a proton bound in ... -
The numerical simulation of a three dimensional fluid sediment system on arbitrarily shaped domains
(2016-07-26)Current driven sediment processes and their impact on the fluid system and on the morphology is of large interest in environmental as well as in engineering sciences. In this thesis both aspects are regarded. In detail, ... -
Numerical Simulation of Droplets with Dynamic Contact Angles
(2015-02-04)The numerical simulation of droplet impact is of interest for a vast variety of industrialprocesses, where practical experiments are costly and time-consuming. In these simulations, the dynamic contact angle is a key ... -
