Reduced-basis method (RBM) for non-affine elliptic parametrized PDEs - (motivated by optimization in hydromechanics)
Dissertation
This work has been motivated by optimizing the efficiency of a ship-propulsion device, the Voith-Schneider Propeller, w.r.t. its steering (determined by the so-called blade-steering curve). We consider a simplified model ...
Characteristics of Poisson cylinder processes and their estimation
Dissertation
In this thesis, we consider stationary Poisson cylinder processes (PCPs). Here, a cylinder is defined as the Minkowski sum of a linear vectorspace and a polyconvex set in the orthogonal space. A PCP is a random set of ...
Betweenness relations
Dissertation
This thesis primarily gives an overview of research on so called betweenness relations with a focus on own contributions to that subject.
Betweenness relations represent a generalisation of the geometric notion that one ...
Unconditional and conditional institutional effects on unemployment: a Bayesian model averaging approach
Dissertation
Labor and product market institutions are regarded as central factors for explaining differences in the evolution of unemployment across countries. It is generally assumed that reforms which serve to reduce institutional ...
Verbesserung der Emissionseigenschaften substratseitig emittierender Vertikallaserdioden
Dissertation
Improved emission properties of bottom-emitting vertical-cavity lasers -
Vertical-cavity surface-emitting lasers (VCSELs) and related devices operating in the 980 nm spectral region are of interest for many applications ...
RFMEMS periodic structures: modelling, components and circuits
Dissertation
The first part of the thesis covers the design of diverse RFMEMS components to be used in unit cells of periodic structures. The developed components include two- and three-state shunt and series switchable capacitors as ...
Flexibilisierung Service-orientierter Architekturen
Bericht
Service-orientierte Architekturen (SOA) werden zunehmend in Unternehmen eingesetzt. Wichtige Ziele bilden die flexible IT-Unterstützung von Geschäftsprozessen, etwa deren rasche Anpassungsfähigkeit sowie die (Teil-) ...
Towards a UML profile on formal semantics for modeling multimodal interactive systems - concepts for modeling interactive systems using standard tools of software engineering
Bericht
An inherent general problem is that systems become more complex. This problem is exacerbated by the use of additional interaction concepts like multimodality.
Interactive systems are widespread and often apply advanced ...
Time-varying copula models for financial time series
Dissertation
The main objective of this thesis is an analysis of the potential time-inhomogeneity in the dependence between multiple financial time series. We focus on suitable inference techniques in the context of a special copula-based ...
Münchner Modell der Früherkennung und Frühen Hilfen für psychosozial hoch belastete Familien: Evaluation der Frühen Hilfen
Dissertation
The "Münchner Modell der Früherkennung und Frühen Hilfen für psychosozial hoch belastete Familien" offers preventive support to families with children up to three years whose situation could lead to neglect or maltreatment ...
