Technologiebezogene Professionalisierung angehender Physiklehrkräfte - Entwicklung und Evaluation eines Lehrkonzepts in der Astrophysik mit digitalen Medien
(2022-09-09)This thesis discusses the development and empirical evaluation of a university course in the form of an astrophysics tutorial that focuses on teaching and learning with digital media. Framed by design-based research, an ... -
TEM in-situ Untersuchungen an Ti-Ni basierten Formgedächtnislegierungen
(2018-05-03)Shape memory alloys (SMAs) are named after their ability to recover plastic deformation upon heating and return to their original undeformed shape. The key mechanism responsible for this behavior is a reversible diffusionless ... -
Temperatureffekte bei der lasererzeugten Kavitation
(2017-04-03)The purpose of this thesis is to examine how the dynamics of single laser-generated bubbles is affected by the water temperature. In addition, the heat transport between a bubble and the surrounding liquid throughout ... -
Test beam studies of pixel detector prototypes for the ATLAS-Experiment at the High Luminosity Large Hadron Collider
(2019-06-26)The upgrade of the Large Hadron Collider (LHC) in the mid-2020’s to the High Luminosity Large Hadron Collider will provide large amounts of data, enabling precision measurements of Standard Model processes and searches for ... -
Testbeam Measurements with Pixel Sensors for the ATLAS Insertable b-Layer Project
(2014-07-04)During the current long machine shutdown of the Large Hadron Collider (LHC) at CERN (Geneva), the innermost part of the ATLAS experiment, the pixel detector, is upgraded. The existing ATLAS pixel system is equipped with ... -
Texturentwicklung in Zwei-Phasen Strömungen
(2006-09-18)Streaming mixtures of fluid and solid phases occur often with different processes, for example, human blood circulation, the Greenforming from ceramics and flow from partially crystallised ... -
The Dependence of the Evolution of Early-Type Galaxies on their Environment
(2006-06-13)This thesis describes the analysis of a data set of 121 elliptical and lenticular (S0) galaxies, located in different environments and at distances corresponding to look-back times between ... -
The Focal Reducing Imager and Spectrograph FORS, built for the optical 16-metre ‘Very Large Telescope’ of the European Southern Observatory
(2006-01-02)This thesis describes the opto- and electro-mechanical concept of a modern astronomical spectrograph with imaging capabilities as it is realized in the ultraviolet-visual FOcal Reducer low ... -
The Influence of Small-Scale Anisotropies and the Large-Scale Environment on the Observed Properties of Lyman-Alpha Emitters
(2014-12-15)Lyman-alpha emitters have become an important tool for the study of star formation, galaxy formation and galaxy evolution. However, the non-linear radiative transport of Lyman-alpha radiation remains a puzzling problem. ... -
The interplay between curvature and composition in binary mixture lipid bilayers
(2016-04-08)In this work we investigate, via computer simulations with an implicit-solvent coarse-grained model, the interplay between curvature and composition in self- assembled lipid structures comprised by two lipid species with ... -
The microstructural investigation of continuous-wave laser irradiated silicon rich silicon oxide
(2017-12-21)In this thesis, we systematically studied optical and structural properties of continuous wave laser irradiated silicon rich silicon oxide by a series of characterization methods: AFM, micro-Raman, micro-PL, HCDF, HRTEM, ... -
The Readout System for the ITk Pixel Demonstrator for the ATLAS High-Luminosity Upgrade
(2020-05-28)The upgrade of the Large Hadron Collider to the High Luminosity Large Hadron Collider starting in 2024 will allow the experiments to collect approximately ten times more data for precision measurements of Standard Model ... -
The reconstitution of visual cortical feature selectivity <i>in vitro</i>
(2018-02-09)Information processing in the nervous system requires the co-ordinated activity of neurons interacting in complex circuits. Despite effort to understand the design principles underlying most neuronal circuits, they remain ... -
The response of the corona to different spatial distributions of heat input
(2014-04-09)Explaining the existence of the million degree corona on top of the much cooler Solar surface has provided scientist with a challenge for a several decades. It is not possible for a cooler object to heat something that ... -
The Scanning Transmission X-Ray Microscope at BESSY II
(2004-02-04)Combining near-edge X-ray absorption fine structure (NEXAFS) spectroscopy and zone plate imaging, scanning transmission X-ray microscopes (STXMs) provide both high chemical sensitivity and ... -
The search for substellar companions to subdwarf B stars in connection with evolutionary aspects
(2011-12-14)The formation and evolution of single hot subdwarf B stars is not entirely understood. Enhanced mass loss during the red giant phase is a prerequisite to explain the very existence of these ... -
The significance of coherent flow structures for the turbulent mixing in wall-bounded flows
(2004-07-28)For the identification and characterisation of coherent flow structures in turbulent boundary layers and for the examination of the interaction processes between these structures, a flat ... -
The solar wind’s geomagnetic impact and its Sun--Earth evolution -- Predictive models for space weather and the Parker Solar Probe orbit
(2018-11-06)This thesis addresses two current topics in solar wind research and space weather. The first study is dedicated to the solar wind's impact on geomagnetic activity and the second study to the estimation of the solar wind ... -
The star formation activity from the centers to the outskirts in intermediate redshift clusters
(2008-06-12)In the local universe, the relative fractions of galaxy types differs in galaxy clusters in comparison to the field. Observations at higher redshift provide evidence that cluster galaxies ... -
