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 ... -
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 ... -
Intermittent Complexity Fluctuations during Ventricular Fibrillation
(2018-01-31)Ventricular fibrillation is a lethal cardiac arrhythmia that is one of the major causes of death worldwide. A prevalent treatment is the application of a high-energy shock using a cardiac defibrillator. These defibrillation ... -
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 ... -
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 ... -
Local- and Cluster Weighted Modeling for Prediction and State Estimation of Nonlinear Dynamical Systems
(2011-08-08)This thesis deals with black-box modeling techniques, in particular local models based on nearest neighbors, and Cluster Weighted Models, which combine a stochastic clustering of the input ... -
Modellierung dynamischer Prozesse mit radialen Basisfunktionen
(2010-12-03)The thesis deals with modeling of nonlinear dynamical systems from measured time series corresponding to a few different values of the system parameters and the dependence of the dynamics ... -
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 ... -
Dynamical modeling with application to friction phenomena
(2005-11-22)The thesis deals with dynamical modeling as an alternative approach to the conventional way of modeling with static models. From the perspective of generalized synchronization the main ... -
Synchronisation chaotisch fluktuierender Halbleiterlaser
(2005-05-04)In this thesis the experimental and numerical synchronization of two optically coupled semiconductor lasers are presented. Of main interest is the synchronization of the well-known low ... -
Hybrid Systems Modeling Manufacturing and Front Dynamics
(2004-06-04)This thesis investigates the dynamics of a certain class of hybrid dynamical systems, so called switched tank systems. By applying switched tank systems as models for manufacturing systems ... -
Approximations and Applications of Nonlinear Filters
(2003-06-04)In this thesis a certain estimation problem for nonlinear stochastic dynamical systems in discrete time, known as filtering in the literature, is considered. The objective is to reconstruct ... -
Nächste-Nachbar basierte Methoden in der nichtlinearen Zeitreihenanalyse
(2001-09-11)The subject of this thesis is the application of nearest-neighbor based methods within the field of nonlinear time-series analysis. A main area of application there is the modeling and ...
