Black Hole Microstate Counting in Four-Dimensional N = 4 String Compactifications
Fischbach, Fabian (2022-01-19)This thesis presents research on the spectrum of supersymmetric Bogomol'nyi-Prasad-Sommerfield (BPS) states in a specific superstring compactification with <em>N</em>=4-extended supersymmetry in four dimensions, known as ... -
Black-Box Parallelization for Machine Learning
Kamp, Michael (2019-10-30)The landscape of machine learning applications is changing rapidly: large centralized datasets are replaced by high volume, high velocity data streams generated by a vast number of geographically distributed, loosely ... -
Blue-Light Sensing in Arabidopsis: In Vivo Microscopy of Subcellular Localization, Endocytosis, and Vesicular Recycling of the Blue-Light Receptor Phototropin 1
Wan, Yinglang (2009-03-13)In this thesis, the subcellular localization and possible functions of the blue light receptor, PHOT1, is examined. Results are presented, which indicate that blue lightinduced relocalization of auxin efflux carriers ... -
Bodengeomorphologie des oberen Bagrot-Tales (Karakorum/Nordpakistan)
Reineke, Thomas (2002)Mit Hilfe eines bodengeomorphologischen Konzepts werden für das im Karakorumgebirge Nordpakistans gelegene obere Bagrot-Tal die unterschiedlichen Bodenbildungen und deren Verteilungsmuster erfasst sowie Limitierungen und ... -
Bodentemperaturmessungen und -simulationen im Lötschental (Schweizer Alpen)
Welpmann, Matthias (2003)In der vorliegenden Dissertation geht es um die Messung und Simulation der Bodentemperatur im Hochgebirge. Die Aufgabenstellungen der Arbeit beinhalten zunächst die Auswertung und qualitative Analyse der im Rahmen dieser ... -
Bone histology and growth of the prosauropod dinosaur Plateosaurus engelhardti MEYER, 1837 from the Norian bonebeds of Trossingen (Germany) and Frick (Switzerland)
Klein, Nicole (2005)Predominately long- and flat bones of the prosauropod <i>Plateosaurus engelhardti</i> from the Norian localities of Trossingen and Frick were sampled for paleohistological study. Both localities yield rich material of adult ... -
BonnMag a Computer Program for Angular Overlap Modeling of all fn-Systems: New Insights into Ligand-field splitting of Lanthanide and Actinide ions
Bronova, Anna (2018-02-16)In this thesis the development of the computer program BonnMag is described. By using BonnMag the excited state energies, magnetic susceptibilities and moments can be calculated for all f<sup>n</sup> systems (1 ≤ n ≤ 13) ... -
Bose-Einstein condensation of erbium atoms for fractional quantum Hall physics
Babik, Daniel Frank (2021-04-21)With the advent of ultracold atomic gases experimentally realized by laser cooling techniques nearly 40 years ago, the doors to accessing novel physical behaviour have been opened wide and far. Experimentally, research in ... -
Bose-Einstein Condensation of Rubidium: Towards Ultracold Binary Bosonic Mixtures
Frese, Daniel (2005)In this thesis, first experiments are reported towards the realization of ultracold Cesium-Rubidium mixtures. In particular, Bose-Einstein condensates (BECs) of Rubidium atoms have been created and combined samples of ... -
Bose-Einstein-Kondensation in einen photonischen Superpositionszustand
Kurtscheid, Christian Philipp (2022-04-21)Die Bose-Einstein-Kondensation ist ein Phasenübergang zu einem Zustand bei dem bosonische Teilchen den Systemgrundzustand makroskopisch besetzen. Dieser besondere Aggregatzustand konnte zunächst mit ultrakalten atomaren ... -
Bose-Einstein-Kondensation von paraxialem Licht
Klärs, Jan (2011-03-02)Einer der faszinierenden Aspekte der Bose-Einstein-Kondensation ist, dass sie selbst in idealen, d.h. wechselwirkungsfreien, Bose-Gasen auftritt, wodurch sie sich grundlegend von allen Phasenübergängen unterscheidet, bei ... -
Bottom-up Object Segmentation for Visual Recognition
Carreira, João Luís da Silva (2013-03-20)Automatic recognition and segmentation of objects in images is a central open problem in computer vision. Most previous approaches have pursued either sliding-window object detection or dense classification of overlapping ... -
BPS state counting using wall-crossing, holomorphic anomalies and modularity
Wotschke, Thomas (2013-07-25)In this thesis we examine the counting of BPS states using wall-crossing, holomorphic anomalies and modularity. We count BPS states that arise in two setups: multiple M5-branes wrapping P x T<sup>2</sup>, where P denotes ... -
Braiding Knots with Topological Strings
Gu, Jie (2015-08-28)For an arbitrary knot in a three-sphere, the Ooguri-Vafa conjecture associates to it a unique stack of branes in type A topological string on the resolved conifold, and relates the colored HOMFLY invariants of the knot to ... -
Brechungsindexänderungen in Lithiumniobat-Kristallen durch Strahlenschäden
Zamani Meymian, Mohammad Reza (2007)Die Bestrahlung der LiNbO3-Kristalle mit <sup>3</sup>He<sup>2+</sup> -Teilchen und einer Energie von ca. 40 MeV erzeugt ein atomares Schäden im Kristall und dies führt zu einer starken ortaufgelösten Brechungsindexänderung ... -
