HappyFace as a monitoring tool for the ATLAS experiment
(2016-10-24)The importance of monitoring on HEP grid computing systems is growing due to a significant increase in their complexity. Computer scientists and administrators have been studying and building effective ways to gather ... -
Hard X-ray Waveguide Optics
(2005-11-18)The thesis is about the preparation of intense hard X-ray nanobeams focusing on the use of X-ray waveguides in resonant beam coupling and front coupling geometry. -
Heizung der Atmosphären Weißer Zwerge durch Zyklotronstrahlung am Beispiel des Polars AM Herculis
(2005-07-13)This thesis investigates the modelling of hydrogen-rich atmospheres of white dwarfs which are irradiated by an external source.Polars are semi-detached close binary systems which consist ... -
Helioseismic diagnostics of solar dynamics in the near-surface layers
(2022-02-08)This thesis proposes to develop new helioseismic diagnostics of solar near-surface flows. In a first part, we discuss the interaction of solar seismic waves (sound waves) with small-scale turbulent convection. The treatment ... -
Herstellung und Charakterisierung metallorganisch deponierter Pufferschichten für YBa2Cu3O7
(2004-01-09)In this work the growth of buffer layers for the high temperature superconductor YBa2Cu3O7 by metal-organic-deposition (MOD) is investigated. Texture formation in CeO2-, Gd-doped CeO2 (CGO)- ... -
Herstellung von Optiken für weiche Röntgenstrahlung und deren Charakterisierung an Labor- und Synchrotronstrahlungsquellen
(2012-03-29)Within the last decades soft X-ray microscopy methods win increasing importance. Labratory-scale laser-induced plasma sources make this radiation available to a larger community of researchers ... -
Heterogene Interdiffusion von nanokristallinen Cu/Co/Au-Schichten
(2002-01-30)The interdiffusion of Cu/Au-thin films is investigated using several analytical and microscopical methods of high resolution. The main part of the experiments was carried out by means of ... -
Hierarchical Mechanical Properties of Wood Cell Wall in Microscale and Nanoscale
(2021-09-21)As one of the remarkable hybrid materials in nature, wood chooses the smartest way to bear mechanical loads by using the least amount of base materials and creates outstanding functional mechanical properties comparable ... -
High Resolution Scattering of He Atoms and D<sub>2</sub> Molecules from the LiF(001) Crystal Surface
(2004-04-14)In this dissertation, a flexible, high-resolution molecular beam apparatus is described which allows surface scattering experiments over a wide range of final angles for fixed incident ... -
High resolution scattering spectropolarimetry of the quiet solar photosphere
(2021-01-14)In this thesis we investigate small-scale scattering polarization signals in quiet, internetwork (IN) regions of the lower solar atmosphere. Small-scale polarization signals are inherently hard to observe due to their ... -
High-Resolution Fluorescence Microscopy with Photoswitchable Fluorescent Proteins
(2009-02-12)The diffraction limit in far-field fluorescence microscopy can be overcome by photoswitching the marker molecules between a fluorescent and a non-fluorescent state. Photoswitching enables ... -
High-Resolution Microscopy with Photoswitchable Organic Markers
(2009-03-23)The resolution of conventional microscopes is limited by Abbe"s diffraction barrier. The resolution barrier, however, can be fundamentally broken by sequentially switching marker substances ... -
High-Resolution Reflection Microscopy via Absorbance Modulation
(2023-01-11)The properties of composite materials are primarily governed by their microstructural features, which can vary in size from a few nanometres to several micrometres. Optical microscopy is one of the primary tools for ... -
High-resolution spectroscopy of low-mass stars
(2015-03-23)High-resolution spectroscopy is employed to investigate a large sample of open cluster low-mass stars. The stellar rotation and magnetic activity of these stars are measured and their correlation is studied. I find in ... -
Higher Order Electroweak and QCD Corrections in e+e−μ+μ− production at LHC
(2022-11-09)This thesis focuses on improving the theoretical modelling of the process pp → e+e−μ+μ− at LHC by including both EW and QCD higher-order perturbative corrections. The EW corrections are studied at NLO fixed order and in ... -
