The assessment of rising and lying down behaviours of dairy cows in cubicle housing systems with regard to animal welfare
(2024)In cubicle housing systems for dairy cows, the lying area is divided into individual lying places called lying cubicles. In these cubicles, contamination of the bedding is limited to reduce resource and labour costs and to promote animal hygiene and health. However, lying cubicle design restricts cow behaviour and limits their freedom of movement. This can be particularly problematic as cows rise to the standing position and lie ...Doctoral Thesis -

Data-Driven Modeling of the Temperature- and Rate- Dependent Large Deformation Behavior of Polypropylene
(2024)Polypropylene is a thermoplastics polymer that have seen growing usage for structural applications in industries such as the automotive sector. Its mechanical behavior under large deformation is characterized by a strong influence of the temperature and rate of deformation, which makes it challenging to model. Many constitutive formulations have been established to describe its salient features: some based on sound physical descriptions ...Doctoral Thesis -

Advancements in Mid-Infrared Colloidal Quantum Dot Photodetectors: Optimization, Metamaterials, and Fabrication
(2024)Photodetectors operating in the mid-infrared spectral wavelength regime are crucial for numerous technologies and scientific advancements. They are integral to a wide array of applications, including biomedical imaging, environmental monitoring, thermal imaging, spectroscopy, and defense systems. However, developing photodetectors that are both highly sensitive and cost-effective remains a significant challenge. Therefore, this doctoral ...Doctoral Thesis -
Structure-activity relationship of Apicomplexan parasite-specific microtubule-interacting drugs and proteins
(2024)Apicomplexan parasites cause diseases such as malaria, toxoplasmosis, or cryptosporidiosis. These single-celled organisms exhibit complex life cycles involving multiple animal hosts. As obligate intracellular parasites, they must invade host cells to replicate. Their cellular structure is highly specialized for invasion, featuring an intricate cytoskeleton and secretory organelle machinery. During invasion, they form a ring-like structure ...Doctoral Thesis -
Implantable Pressure Sensor Encapsulation for Ventricular Assist Device Control
(2024)Autonomous feedback controlled ventricular assists device (VAD) operation promises a plethora of benefits such as increased patient safety, comfort, and reduced healthcare costs. Current generation VADs operate at static pump speeds due to the lack of available biocompatible, long-term stable pressure sensor systems. In this thesis, a pressure sensor encapsulation was developed and integrated in an inflow cannula for a VAD and in an ...Doctoral Thesis -

A Polymorphic Control Framework for Robot-Assisted Neurorehabilitation
(2024)The leading cause of long-term disability and acute hospitalization in high-income countries is stroke, with more than 13.7 million new cases worldwide each year. Stroke often results in paralysis of the limbs. To recover from lost functionality, long-term, intensive neurorehabilitation addressing individualized tasks and active participation of the patient is needed. To relieve the therapists from parts of the physical workload, to ...Doctoral Thesis -

Multimode cavity optomechanics with levitated nanoparticles
(2024)Optically levitated nanoparticles in vacuum have emerged as a promising platform to study macroscopic quantum states. These studies will deepen our understanding of quantum mechanics at large mass and length scales and enable the next generation of quantum technologies, including force sensors. A major goal in the field of levitodynamics is entangling the motion of two distant nanoparticles. Generating entanglement requires quantum control ...Doctoral Thesis -
The roles of rare-earth ions in ABO3 compounds: More than meets the eye
(2024)Rare-earth ABO3 compounds are known to show a multitude of intriguing phenomena ranging from colossal magnetoresistance [1] over metal-to-insulator transitions [2] to multiferroicity [3]. The rare-earth elements in such compounds can influence the properties of the material in various ways, which is the focus of the investigation in this thesis. Three different influence pathways of the rare-earth ion are discussed here: via the rare-earth ...Doctoral Thesis -
