Parameterschätzung und Modellevaluation für komplexe Systeme
(2016-10-17)Mathematical models in form of dynamical systems play an important role in many disciplines, such as system biology, engineering, or physics. They are widely used to simulate the time evolution of the internal states of ... -
Particle - Tracking - Velocimetry - Messungen an kollabierenden Kavitationsblasen
(2008-12-01)The flowfields around cavitation bubbles collapsing near obstacles are investigated in this work. For this purpose, photographs of the laser-induced bubbles are taken and the method of ... -
Ratiometric fluorescence imaging and marker-free motion tracking of Langendorff perfused beating rabbit hearts
(2021-01-06)Optical mapping is a fluorescence based imaging technique used extensively in cardiac research to study the electrophysiological properties of isolated hearts kept at physiological conditions. The major limitation of ... -
Real-time Magnetic Resonance Imaging
(2010-01-26)In this PhD thesis a generic solution for real-time MRI was developed based on a comprehensive analysis of the physical requirements. The method combines the fast low angle shot (FLASH) acquisition principle with a radial ... -
Real-time MRI and Model-based Reconstruction Techniques for Parameter Mapping of Spin-lattice Relaxation
(2017-09-05)Magnetic resonance imaging (MRI) is a non-invasive technique widely used for imaging of humans and animals. It came into existence based on several fundamental inventions made in the 1970s. Since then, MRI has evolved into ... -
Einen Roboter das Fahren Lehren - ein auf Fähigkeitslernen basierter Ansatz
(2010-12-08)Robots can alleviate our lives by accomplishing tasks that are unpleasant or even dangerous for us. To employ them efficiently they should be autonomous, adaptive, and easy to instruct ... -
Stabilisierung und Kontrolle komplexer Dynamik durch mehrfach zeitverzögerte Rückkopplung
(2007-06-20)Multiple Delay Feedback Control (MDFC) based on multiple independent and individually weighted delay times is introduced and shown to be an efficient method for stabilizing fixed points ... -
Symmetry Breaking and Pattern Selection in Models of Visual Development
(2010-10-13)Response properties of neurons in the visual cortex form spatial representations called maps of several stimulus features such as orientation preference (OP) or ocular dominance (OD). This ... -
Synchronisation Behaviour of Viscoelastically Coupled Self-Sustained Oscillators as Models for Oscillations of Premature Cardiomyocytes
(2017-11-22)This thesis analyses how the synchronisation behaviour of self-sustained oscillators is influenced by the viscoelastic properties of their coupling. This question is motivated by the early development stage of artificial ... -
Temperatureffekte bei der lasererzeugten Kavitation
(2017-04-03)The purpose of this thesis is to examine how the dynamics of single laser-generated bubbles is affected by the water temperature. In addition, the heat transport between a bubble and the surrounding liquid throughout ... -
The Time Course of Negative Priming
(2010-03-23)Selective attention enables goal-directed behavior despite the permanent, immense input to the sensory system. Contradicting early speculations of an active attending and passive ignoring, ... -
Thermal Convection: Differential heating, travelling thermal waves and turbulent superstructures
(2022-05-30)Turbulent thermal convection is ubiquitous in geophysical, astrophysical, and industrial applications. In the present work, various phenomena in the convective paradigm systems of horizontal convection and Rayleigh-Bénard ... -
Tissue-organization of Oscillating Cardiomyocytes via Matrix-mediated Biomechanical Signals
(2020-02-04)Tissue engineering, specifically engineered human myocardium (EHM), offers a promising therapeutic perspective for patients suffering from heart failure and also might improve drug development and testing. We therefore ... -
Transient integral boundary layer method to simulate entrance flow conditions in one-dimensional arterial blood flow
(2006-10-20)Motivation: The pressure drop -- flow relations in myocardial bridges and the assessment of vascular heart disease via fractional flow reserve (FFR) have motivated much research during the ... -
Transport in nicht-hermiteschen niedrigdimensionalen Systemen
(2012-01-05)In this work, scientific methods and findings known from mesoscopic physics, primarily used for semiconductor nanostructures, will be transferred to photonic systems, enabled by the analogy ... -
Ultraschallunterstützte Kupferabscheidung
(2017-08-03)The electroless and electrolytic copper deposition are essential process steps in the production of printed circuit boards. Various studies have already shown that ultrasound can improve these processes. However, ultrasound ... -
Wetting dynamics on soft surfaces
(2023-03-01)Dynamic wetting of a liquid deposited on a soft solid is very common in many biological, medical, and industrial processes. Thus, understanding the interaction between a moving liquid drop and a soft surface remains crucial, ...
