Exploiting Structural Signal Information in Passive Emitter Localization
Steffes, Christian (2017-08-22)The operational use of systems for passive geolocation of radio frequency emitters poses various challenges to single sensor systems or sensor networks depending on the measurement methods. Position estimation by means of ... -
Exploration of advanced CMOS technologies for new pixel detector concepts in High Energy Physics
Hemperek, Tomasz (2018-04-19)This thesis presents the author’s original concepts for the development of radiation hard monolithic pixel sensors that can replace hybrid pixel sensors in high energy physics experiments. It presents one of the first ... -
Exploration of bioresources enables detection and characterization of natural products with antibacterial activities and elucidation of the corresponding biosyntheses for derivative generation
Böhringer, Nils (2021-11-17)The discovery of antibiotics in the early 20th century sparked a medicinal revolution, which for the first time in history enabled humankind to effectively combat bacterial infections. Despite this immense success, the ... -
Exploring Dark Matter Properties from the Smallest to the Largest Scales
Bradač, Maruša (2004)One of the main problems in cosmology is to understand the formation and evolution of galaxies, galaxy clusters, and large-scale structure. Whereas the basics of the current Cold Dark Matter (CDM) paradigm for structure ... -
Exploring exotic states with twisted boundary conditions
Agadjanov, Dimitri (2017-10-24)The goal of this thesis is to develop methods to study the nature and properties of exotic hadrons from lattice simulations. The main focus lies in the application of twisted boundary conditions. The thesis consists of a ... -
Exploring non-coding mitochondrial DNA sequences in bryophyte molecular evolution
Volkmar, Ute (2010-04-28)The thesis presented here focussed on the molecular evolution of non-coding mitochondrial DNA in liverworts and mosses.<br /> To address remaining questions in moss phylogeny, three mitochondrial gene regions were investigated ... -
Exploring Non-Equilibrium in Ultracold Fermi Gases and Machine Learning in Physics
Link, Martin (2021-05-21)This thesis covers two fields of research carried out in the context of ultracold Fermi gases: Non-equilibrium physics in the BEC-BCS crossover and the use of machine learning methods in physics. <br /> The BEC-BCS ... -
