Stabilization strategies for discontinuous Galerkin methods

Benjamin Stamm

The subject of this thesis is the analysis of discontinuous Galerkin methods for linear partial differential equations of first or second order. Discontinuous Galerkin methods are known to satisfy a local mass conservation property. Taking a closer look on ...

Coordination measurements in compacted NaCl irregular powders using X-ray microtomography

Andreas Mortensen

X-ray microtomography and three-dimensional (3D) image analysis are used to quantify the structural evolution during cold isostatic compaction of two irregularly shaped NaCl powders having different mean particle sizes (75 and 400 mu m) and somewhat differ ...

PDE constrained optimization and design of frozen mode crystals

Jan Sickmann Hesthaven

We explore the use of PDE constrained nonlinear optimization techniques to optimize and design electromagnetic crystals which exhibit frozen mode behavior. This is characterized by Van Hove singularities in the dispersion relation, e.g., stationary reflect ...

Delocalized surface modes reveal three-dimensional structures of complex biomolecules

Sylvie Roke

Interfaces are important for many processes in chemistry, physics, and biology. Crucial to their properties are the details of the three-dimensional structure of the participating (macro)molecules. Vibrational Sum Frequency Generation (VSFG) is a tool spec ...

Optimal flow control for Navier-Stokes equations: drag minimization

Luca Dede'

Optimal control and shape optimization techniques have an increasing role in Fluid Dynamics problems governed by partial differential equations (PDEs). In this paper, we consider the problem of drag minimization for a body in relative motion in a fluid by ...

Spectral Methods

Alfio Quarteroni

Spectral methods, particularly in their multidomain version, have become firmly established as a mainstream tool for scientific and engineering computation. While retaining the tight integration between the theoretical and practical aspects of spectral met ...

Vector potential - Vorticity relationship for the Stokes flows. Application to the Stokes eigenmodes in 2D/3D closed domain

Emmanuel Leriche

The core dynamics of the Stokes eigenmodes subjected to satisfy no-slip boundary conditions on any 2D closed contour, or 3D surface, is shown to be characterized by a linear differential functional relationship between the vector potential and vorticity, $ ...

Bio-inspired cellular machines

Fabien Vannel

Information technology has only been around for about fifty years. Although the beginnings of automatic calculation date from as early as the 17th century (W. Schickard built the first mechanical calculator in 1623), it took the invention of the transistor ...

Simulation and Optimization of Partial Differential-Algebraic Equations with a Separation of Time Scales

Benoît Chachuat

Problems that exhibit multiple time scales arise frequently in many scientific and engineering fields. The modeling and simulation of such systems leads naturally to singular perturbation models. For systems of partial differential-algebraic equations (PDA ...

Boundedly generated groups with pseudocharacter(s)

Nicolas Monod

A note presenting the first examples of groups that are boundedly generated, have property (T) and have a one-dimensional space of pseudocharacters. ...
