Thin Viscous Films on Curved Geometries
(2014-08-29)
The topic of this thesis is the evolution of thin viscous films on curved substrates. Using techniques from differential geometry, namely the exterior calculus of differential forms, and from optimization theory, in ...
Factorization of holomorphic eta quotients
(2014-12-12)
We conjecture the occurrence of a certain type of factor of a holomorphic eta quotient whenever it is reducible and we prove this conjecture for all prime power levels. In particular, this also implies that rescaling and ...
L2-index theory, the Chern conjecture, and manifolds of special holonomy
(2014-12-12)
In this dissertation we study a conjecture attributed to Chern and Hopf, a generalization of Atiyah's L2-index theorem used by Gromov to prove said conjecture for Kähler manifolds, and an extension to Kähler ......
Experimental and numerical description of rapid granular flows and some baseline constraints for simulating 3-dimensional granular flow dynamics
(2014-07-25)
Accurate prediction of rapid granular flow behavior is essential to optimize protection measures from hazardous natural granular flows like snow avalanches and landslides and to design efficient production facilities for ...
Koordination und Kooperation von Mehrrobotersystemen unter spatialen Nebenbedingungen
(2014-10-07)
Schon die Steuerung eines einzelnen Roboters ist komplex und erfordert oft ein intensives Training. Soll ein System aus mehreren Robotern kontrolliert werden, potenziert sich diese Schwierigkeit. Zudem müssen neben dem ...
Von einzelnen H-Brücken zum chemischen Rezeptor: 2D-IR-Spektroskopie wasserstoffverbrückter Systeme
(2014-08-22)
Die hier vorliegende Arbeit liefert grundlegende Erkenntnisse zum Verständnis der dynamischen Entwicklung intra- und intermolekularer Wasserstoffbrückenbindungen. Der supramolekulare Wirt-Gast-Komplex 18-Krone-6-Monohydrat, ...
Flat Fronts and Stability for the Porous Medium Equation
(2014-08-26)
This work shows stability of general solutions of the porous medium equation close to flat travelling wave fronts in the sense of homogeneous Lipschitz spaces under rather weak conditions on the initial data that are optimal ...
Promoter regulation of the Craterostigma plantagineum Cp LEA-like 11-24 gene and functional characterization of its transcription factor (CpbZIP1)
(2014-08-26)
The resurrection plant Craterostigma plantagineum, a member of Linderniaceae family, is distributed in areas with variable water availability in Southern Africa. Two closely related species, L. brevidens which is endemic ......
Erzeugung intensiver spinpolarisierter Elektronenstrahlen an der Beschleunigeranlage ELSA
(2014-09-05)
An der Elektronen-Stretcher-Anlage ELSA des Physikalischen Instituts der Universität Bonn werden derzeit hadronenphysikalische Doppelpolarisationsexperimente im Rahmen des transregionalen Sonderforschungsbereichs SFB/TR ...
Search for R-parity violating Supersymmetry in multi-lepton final states with the ATLAS detector
(2014-08-29)
The benchmark scenario BC1 is an example of an R-parity violating supersymmetric (SUSY) model with one lepton number violating coupling, lambda121. Its lightest supersymmetric particle is the stau1, ...
