Investigation of the Nonlinear Optical Properties of Metamaterials by Second Harmonic Generation
(2013-11-27)
Metamaterials have attracted tremendous attention in the past decade because they allow researchers to engineer new optical properties by designing a new optical material. In particular, metamaterials are regarded as the ......
Elektronenstruktur von Molekülkristallen: Anwendung quantenchemischer Methoden und Entwicklung neuer Modelle
(2013-10-30)
Im Rahmen dieser Arbeit wurden bewährte periodische und moderne Multireferenz- Methoden zur Beschreibung der Elektronenstruktur von Molekülkristallen angewendet sowie ein alternativer Ansatz, das ab initio zyklische ......
Multiscale Modelling and Simulation of Rapid Granular Flows
(2013-11-19)
Granular flows are often encountered in geophysical contexts like debris flows, snow and rock avalanches, and also in transport processes in engineering applications. The damage caused by geophysical mass flows can be huge. ...
Low mass hybrid pixel detectors for the high luminosity LHC upgrade
(2013-11-11)
Reducing material in silicon trackers is of major importance for a good overall detector performance, and poses severe challenges to the design of the tracking system. To match the low mass constraints for trackers in High ...
Die Rolle von TNFα in der Blaseninfektion
(2013-11-19)
Makrophagen und neutrophile Granulozyten sind bedeutsame Phagozyten des innaten Immunsystems, die in Zusammenarbeit eine Vielzahl von bakteriellen Infektionen auflösen. Die funktionelle Spezialisierung dieser Zellen und ......
Modular Functions and Special Cycles
(2013-11-27)
In this thesis we study algebraic cycles on Shimura varieties of orthogonal type. Such varieties are a higher dimensional generalization of modular curves and their important feature is that they have natural families of ......
The role of the cannabinoid receptor 2 in the modulation of neuropathic pain
(2013-11-19)
Neuropathic pain is a debilitating, chronic pain condition associated with inflammation or injury of peripheral and central nerves (Milligan and Watkins, 2009). The existing pharmacotherapies either lead to an inadequate ...
Untersuchung der Angiotensin II-Typ 1-Rezeptor-vermittelten kontraktilen Signalwege in der hepatischen Fibrose
(2013-09-19)
In chronischen Leberschäden trägt das Renin-Angiotensin-System (RAS) zur hepatischen Fibrose bei. Daher dient die Erforschung der intrazellulären Signalwege des Angiotensin II-Typ 1-Rezeptors (AT1R) dem besseren Verständnis ...
Detector Optimization Studies and Light Higgs Decay into Muons at CLIC
(2013-09-27)
The Compact Linear Collider (CLIC) is a concept for a future e+e- linear collider with a center-of-mass energy of up to 3 TeV. The design of a CLIC experiment is driven by the requirements related to ...
Approximability of Combinatorial Optimization Problems on Power Law Networks
(2013-10-30)
One of the central parts in the study of combinatorial optimization is to classify the NP-hard optimization problems in terms of their approximability. In this thesis we study the Minimum Vertex Cover (Min-VC) problem and ...
