Developement of Diagnostic Tools to Decipher Para- and Endocrine Effects of IFN Tau
(2018)Reproductive success is indispensable for efficient animal husbandry of modern dairy farms. Nevertheless, embryonic losses occur in every second cow during the first three weeks of gestation. The comprehension of key factors involved in the reproduction events is thus a prerequisite to reveal dysregulations. The protein Interferon tau (IFN tau) is the major pregnancy recognition signal in ruminants. It is not only responsible to extend ...Doctoral Thesis -

Changes of the Body Composition of Modern Pig Genotypes During Growth as Depending on the Dietary Protein Supply
(2018)Genetic selection towards leaner pigs has led to changes in chemical composition, growth rates, feed intake (FI), nutrient requirements and, possibly, differences in nutrient use efficiency. This thesis is part of a larger project aiming at revising the feeding recommendations for modern Swiss Large White pigs. Targeted nutrition of the current genotypes is also necessary for the improvement of nutrient use efficiency which is one of the ...Doctoral Thesis -
Evaluating Symmetry and Order in Urban Design
(2019)Symmetry and order are among the fundamental principles in architecture and urban design. Although symmetry and order are often associated with each other, the ways we think about the two are different. Symmetry has a precise mathematical definition; thus, in principle, it is possible to compute it. Order, in contrast, is a very vague and subjective notion. The goal of this work is to establish a link between computable symmetry and ...Doctoral Thesis -
Refining LA-ICP-MS Data Acquisition and Interpretation Methods for the Zircon Geochronometer in Tertiary Magmatic Systems
(2018)Understanding the mechanisms that govern the evolution of magmatic systems necessitates a firm grasp on their respective timescales. To this end, a variety of mineral chronometers is employed, most notably the U-Pb system in zircon. While high-resolution methods such as isotope dilution thermal ionization mass spectrometry (ID-TIMS) provide unparalleled insight into the temporal evolution of silicic magmatic systems, the time-intensive ...Doctoral Thesis -
Soft-Robotic-Driven Adaptive Photovoltaic Building Envelopes
(2018)Current building envelopes are predominantly static, manually operated, and do not have integrated energy harvesting devices. As opposed to this, kinetic building envelopes with integrated photovoltaics, have the potential to improve building energy performance and occupant comfort by regulating solar heat gains and natural lighting while simultaneously generating electricity on site. If equipped with reflecting elements, the adaptive ...Doctoral Thesis -
Climate Adaptive Building Solutions Based on the Autonomous Movement of Wooden bi-layered Structures
(2018)The global warming due to green-house effects and their negative consequences, calls for new renewable and sustainable engineering building solutions. Climate Adaptive Building Shells (CABS) are currently object of many researches, because of their energy saving potential based on autonomous responsiveness to changing climate conditions. However, the most part of CABS systems currently available on the market are driven and controlled by ...Doctoral Thesis -

A Parallel Space-Time Solver for the Navier–Stokes Equations with Periodic Forcing
(2018)Many problems in science and engineering are driven by time-periodic forces. In fluid dynamics, this occurs for example in turbines, rotors or in human blood flow. These problems are described by the Navier–Stokes equations. The traditional way to solve them is to use a time-stepping method and compute the whole transitional phase until the time-periodic steady state is reached. We are using a different approach. We model directly ...Doctoral Thesis -

Ice clouds: from ice crystals to their response in a warming climate
(2018)Atmospheric ice crystals form from a variety of different sources and at different temperatures. Between 0 °C and -38 °C, liquid water and ice crystals can coexist. Cloud ice initiated by freezing of cloud droplets at these temperatures needs to be catalyzed by an ice nucleating particle (INP). Further growth then often involves collisions of ice crystals and cloud droplets or depositional growth of the ice crystals at the expense of the ...Doctoral Thesis -
Experimental Characterization of Pilot-Fuel Ignition, Combustion, and Soot Formation in Dual-Fuel Combustion Systems
(2018)In recent years, many natural gas-fueled engine concepts have emerged for transportation, as well as stationary applications. They seem as an attractive solution to meet current and upcoming emission legislations at uncompromised efficiency. Furthermore, the application of natural gas is advantageous regarding the associated CO2 reduction, high resistance to auto-ignition (knock), and low sooting propensity. Especially in the large engine ...Doctoral Thesis -
On Efficient Data Exchange in Multicore Architectures
(2018)TIK-SchriftenreiheIn contemporary multicore architectures, three trends can be observed: (i) A growing number of cores, (ii) shared memory as the primary means of communication and data exchange and (iii) high diversity between platform architectures. Still, these platforms are typically programmed manually on a core-by-core basis; the most helpful tool that is widely accepted are library implementations of frequently used algorithms. This complicated ...Doctoral Thesis
