Activity of M dwarfs in the CARMENES sample
(2021-11-16)The Calar Alto high-Resolution search for M dwarfs with Exo-earths with Near-infrared and optical Echelle Spectrographs (CARMENES) has been searching and finding planets for five years by looking for periodic Doppler-shift ... -
Adaptive Scanning for STED Microscopy
(2020-02-06)Optical nanoscopy allows for highly specific imaging of biological tissue, cellular components and even single molecules and has therefore become an integral part of modern biomedical research. In STED microscopy, being ... -
AdS/CFT Holography of the O(N)-symmetric $\phi^4$ Vector Model
(2008-01-10)We study the AdS/CFT correspondence at the example of the renormalization group IR and UV fixpoint theories of a Euclidean O(N)-symmetric vector field theory with $(\underline \phi^2)^2$ interaction in 2 dimensions. These ... -
Advanced Data Processing in Super-resolution Microscopy
(2017-08-23)Super-resolution fluorescence techniques enable the study of structures smaller than the diffraction limit with visible light microscopy. Their introduction and development within the last two decades opened up the ... -
Advanced multiplexing techniques in single molecule localisation microscopy
(2022-05-13)DNA point accumulation for imaging in nanoscale topography (DNA-PAINT) is a powerful super-resolution technique highly suitable for multi-target (multiplexing) bio-imaging applications. However, multiplexed imaging of cells ... -
Advanced x-ray multilayer waveguide optics
(2017-09-12)The aim of this thesis is to demonstrate that x-ray waveguide optics can be gen- eralized from a single guiding film to an array of planar waveguides, enabling more complex and controllable phenomena of field propagation ... -
Aerodynamische Wirkung schnell bewegter bodennaher Körper auf ruhende Objekte
(2017-06-23)In an unsteady flow field pressure variations lead to aerodynamic loads on objects like spheres or disks. Under the assumption of inviscid flow, the potential flow theory is a suitable method to predict aerodynamic loads ... -
Aerothermodynamische Untersuchung einer Wiedereintrittskonfiguration und ihrer Komponenten in einem impulsbetriebenen Hochenthalpie-Stoßkanal
(2008-05-30)During re-entry into the atmosphere of the earth at altitudes between 60 km to 80 km above ground, the kinetic energy of a re-entry vehicle is converted mostly into thermal energy of the ... -
AFM Untersuchungen an smektischen Flüssigkristallen
(2009-08-12)This thesis presents an experimental study of focal conic domains in smectic liquid crystal films on solid substrates. Focal conic domains are complex structures in smectic phases and are ... -
Aggregation and Gelation in Random Networks
(2010-06-23)In this thesis the formation, elasticity, and structure of randomly cross-linked networks is investigated analytically and with the help of computer simulations. In the first two chapters, ... -
Akustische Beeinflussung einer Instabilität in Kanälen mit überströmten Resonatoren
(2006-09-01)The sound-flow interaction in an acoustically lined section of an otherwise rigid duct is investigated. Turbulent fluctuations or imposed oscillations of the flow at the inlet of the lined ... -
Akustische Strömung in Wasser durch Ultraschall im UHF-Bereich
(2021-06-07)The goal of this predominantly experimental work is the understanding and investigation of acoustic streaming, which is generated by the sound field of new type of a very high frequency transducers. The transducers have ... -
Amorphe weichmagnetische CoFeNiSiB-Detektionsschichten in Spinventilen
(2003-04-17)Co-based amorphous magnetic films as detection layer in magnetoresistive systems are an attractive alternative instead of crystalline Ni81Fe19, as they are very soft magnetic, ... -
Amplituden- und phasenaufgelöste Polariton-Pulspropagation in GaAs bei niedrigen und mittleren Elektron-Loch-Plasmadichten
(2002-03-01)High resolution amplitude and phase measurements with interferometric crosscorrelation are reported on polariton pulse progapation through ultrapure Galliumarsenide. The measurement technique and various pump and probe ... -
Analyse der Glättung rauer Oberflächen durch Dünnschichtdeposition
(2009-08-17)In this dissertation it is investigated if and to what extent it is possible to smooth a rough surface by deposition of a thin film. The theory of roughening and smoothing due to growth ... -
Analysis of Coronal Mass Ejection Kinematics and Dependencies on Source Region Properties
(2020-02-24)Coronal Mass Ejections (CMEs) are outbursts of coronal plasma bound in magnetic structures that are explosively accelerated. Their evolution into the heliosphere can be observed with coronagraphs and heliospheric imagers, ... -
Analysis of historical solar observations and long-term changes in solar irradiance
(2017-10-25)The Sun is the main external driver of Earth's climate. Various mechanisms of the solar influence on climate have been proposed. The debate is ongoing, but variation in the radiative flux of the Sun is among the main ... -
Analysis of MIRO/Rosetta Data
(2019-02-12)In August 2014, the Rosetta spacecraft completed its ten year journey when it arrived at its target destination, the comet 67P/Churyumov-Gerasimenko. The Rosetta mission was a flagship endeavour for the European Space ... -
