Processes of structure formation in copolymer systems
(2024-11-15)Block copolymers exhibit complex properties, such as self-assembly capabilities and viscoelasticity, making them indispensable in various industries and scientific fields. Their ability to create ordered microscopic ... -
Characterization and modeling of ultrasound propagation and cavitation in confined flow geometries
(2024-07-08)Acoustic cavitation is a process by which small bubbles are formed in a liquid that is exposed to sound waves such as ultrasound. These bubbles are peculiar because they expand and collapse violently on themselves resulting ... -
Toward Trustworthiness of Deep Learning Models for 12-Lead ECGs
(2024-01-31)A 12-lead electrocardiogram (ECG), a common examination tool in cardiology, represents the electrical activity of the heart as waveforms. Predictions and classifications with deep learning (DL) algorithms show great potential ... -
Data Analysis of Musical Timeseries
(2024-01-08)Music, despite its ubiquitous familiarity, is surprisingly hard to define. Should one consider its acoustic features, the mechanics by which it is produced and performed, as well as the cultural norms attached to them, ... -
Investigation of Physical and Chemical Effects in Sonicated Small Flow Channels
(2023-09-08)In the framework of intensification of chemical processes, miniature continuous flow reactors have come into focus in recent time. As a specific way of “non-classical” energy supply to the liquid in such a flow reactor, ... -
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, ... -
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 ... -
Akustische Strömung in Wasser durch Ultraschall im UHF-Bereich
(2021-06-07)The goal of this predominantly experimental work is the understanding and investigation of acoustic streaming, which is generated by the sound field of new type of a very high frequency transducers. The transducers have ... -
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 ... -
Ballistic electron transport in graphene nanodevices and billiards
(2019-10-17)Nanodevices are objects with broad relevance for today's society, which bases its economy, operation, and communication onto digital resources. In ballistic nanodevices, disorder has either negligible or minor impact on ... -
Dynamic Responses of Networks under Perturbations: Solutions, Patterns and Predictions
(2018-05-31)External perturbations are omnipresent in the dynamics of oscillator networks across biology, physics and engineering. How such networks dynamically respond to fluctuating perturbation signals fundamentally underlies their ... -
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 ... -
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 ... -
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 ... -
