Modeling ripple formation
(2004)
The aim of this thesis was to approach the problem of ripple formation by a model which describes the phenomenon on a macroscopic scale and does not incorporate the detailed dynamics of the fluid flow field. We developed ...

(2004)
Estimating Synchronization in Dynamical Systems with Cellular Neuronal Networks
Over the past decade synchronization phenomena in dynamical systems have attracted much attention in various scientific ...

Nonequilibrium Effects in Strongly Correlated Systems
(2004)
The dynamical mean field theory is extended using the Keldysh Green's function formalism to study strongly correlated systems away from equilibrium. This technique has been applied to two different systems, whose insulating ...
Erzeugung von Nanostrukturen mit laserpräparierten thermischen Atomstrahlen
(2004)
Gegenstand dieser Arbeit ist die Erzeugung von Nanostrukturen mit optisch kollimierten, thermischen Atomstrahlen. Im ersten Teil (Kap. 2-4) werden neue Konzepte und Experimente zur Atomlithografie mit Dipolkraft-Lichtmasken ...
Stochastic many-particle systems far from equilibrium coupled to bulk reservoirs
(2004)
In this work the influence of bulk reservoirs on lattice models for many-particle systems far from equilibrium is studied.
A hydrodynamic equation is presented that allows to compute the steady state density profile ...

Multiple point interactions in lattice gas models far from equilibrium
(2004)
In this work non-equilibrium phenomena in statistical models with more than nearest neighbor interactions are examined. The investigated models belong to three different types of non-equilibrium, i.e. systems undergoing ...
Measurement of high-Q2 charged current cross sections in e+p deep inelastic scattering at HERA
(2004)
Cross sections for charged current deep inelastic scattering have been measured in e+p collisions at a center-of-mass energy of 318 GeV. The data collected with the ZEUS detector at HERA in the ...
Zustandsklassifikation von nichtlinearen dynamischen Systemen mit Zellularen Neuronalen Netzen und mit Untersuchung des Phasenskalierungsverhaltens
(2004)
During the last years different methods from non-linear time series analysis have been successfully applied to classify the dynamics of complex systems in a number of disciplines, including physics, astrophysics, biology, ...
MAPON-Untersuchungen am System 82BrFe
(2004)
Mit Hilfe der Tieftemperaturkernorientierung LTNO (Low Temperature Nuclear Orientation) haben frühere Messungen der Hyperfeinwechselwirkung im System 82BrFe (hergestellt durch ...
The decay of the γp system into the pπ0η final state
(2004)
Photoproduction of mesons provides an excellent tool for accessing properties of baryon resonances. Most existing data sets on baryon resonances have been measured in \pi N scattering experiments; photoproduction experiments ...
