Punktdefekte in Verbindungshalbleitern untersucht mit der gestörten Winkelkorrelation
(2013-05-29)
Die Dissertation befasst sich mit der Charakterisierung von dotierten Halbleitern, im Speziellen mit AlN, GaN, deren ternäres Verbindungssystem AlGaN und ZnO. Diese Halbleiter mit Wurtzitstruktur finden bereits eine breite ...
Extraction of Fragmentation Functions from Charged Kaon and Pion Production at COMPASS
(2013-12-16)
Quark helicity distributions can be accessed by measuring spin asymmetries in polarised deep-inelastic scattering, but for a full flavour separation the precise knowledge of quark fragmentation functions is essential. Those ...
Single atom interferometers and Bloch oscillations in quantum walks
(2013-05-22)
The deliberate coherent manipulation of a single atom's spin and position in an optical lattice has great potential as a primitive for future quantum simulators. This thesis investigates position control on ultracold Caesium ...
Analysis and Manipulation of Repetitive Structures of Varying Shape
(2013-05-22)
Self-similarity and repetitions are ubiquitous in man-made and natural objects. Such structural regularities often relate to form, function, aesthetics, and design considerations. Discovering structural redundancies along ...
Image-Based Approaches to Hair Modeling
(2013-06-06)
Hair is a relevant characteristic of virtual characters, therefore the modeling of plausible facial hair and hairstyles is an essential step in the generation of computer generated (CG) avatars. However, the inherent ...
From Acoustic Mismatch Towards Blind Acoustic Model Selection in Automatic Speech Recognition
(2013-05-24)
Acoustic distortion and acoustic mismatch are two of the most critical aspects influencing automatic speech recognition. A speech signal recorded from a speaker in a certain acoustic environment compared to a signal from ...
Enzymersatztherapie der metachromatischen Leukodystrophie: Untersuchungen zur Steigerung des Übertritts der Arylsulfatase A über die Blut-Hirn-Schranke durch die Verwendung von Peptidvektoren
(2013-05-31)
Metachromatische Leukodystrophie (MLD) ist eine lysosomale Speicherkrankheit, die durch die Defizienz des lysosomalen Enzyms Arylsulfatase A (ASA) hervorgerufen wird. Zur klinischen Behandlung ist für einige lysosomale ...
Efficient implementations of high-resolution wideband FFT-spectrometers and their application to an APEX Galactic Center line survey
(2013-06-13)
Spectroscopy has been a major technique in radioastronomy for decades and spectrometers are used in a wide range of radioastronomical applications. With more stable receivers that are wider in bandwidth, spectrometers are ...
Investigations into interferon response of novel bat cell cultures upon alphavirus infection
(2013-06-13)
Bats have been identified as reservoir for human pathogenic zoonotic viruses like Rabies, Marburg or Henipaviruses. The fact that bats carry viruses without showing clinical symptoms, raised the question if these flying ...
Coupling of Proton Transfer and Multidrug Expulsion in the Inner Membrane Translocase AcrB
(2013-07-24)
With the introduction of the first antibiotics in the 1940s, lethal bacterial infections like tuberculosis or pulmonary inflammation were widely believed to be defeated. However, bacteria inherently hold a variety of ...
