Verbesserung der Emissionseigenschaften substratseitig emittierender Vertikallaserdioden
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
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
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
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 ...
Concurrent programming for scalable web architectures
Abschlussarbeit (Master; Diplom)
Web architectures are an important asset for various large-scale web applications, such as social networks or e-commerce sites. Being able to handle huge numbers of users concurrently is essential, thus scalability is one ...
PKCalpha is genetically linked to memory capacity in healthy subjects and to risk for posttraumatic stress disorder in genocide survivors
Strong memory of a traumatic event is thought to contribute to the development and symptoms of posttraumatic stress disorder.
A new approach to object recognition
In this thesis a new approach to object recognition will be introduced. The basic idea of the approach is to compare two combinations of half ellipses representing two objects in order to find out whether the combinations ...
Age-related changes in neural functional connectivity and its behavioral relevance
Background: Resting-state recordings are characterized by widely distributed networks of coherent brain activations. Disturbances of the default network - a set of regions that are deactivated by cognitive tasks and activated ...
We introduce a measure for the computational complexity of individual instances of a decision problern and study some of its properties. The inntance complexity of a string x with respect to a set A and time bound t, ic ...
"Relative termination" is a property that generalizes both termination and "termination modulo". In order to prove that a term rewrite system relatively terminates, one may reuse the common termination quasiorderings. ...
