Hardwarearchitekturen im Kontext von Eingebetteten Systemen werden immer komplexer und bewegen sich zukünftig immer häufiger in Richtung von Multi- oder Manycore-Systemen. Damit diese Systeme ihre optimale Leistungsfähigkeit – für die oftmals speziellen Aufgaben im Kontext von Eingebetteten Systemen – ausspielen können, beschäftigen sich ganze Forschungszweige mit der anwendungsspezifischen Maßschneiderung dieser Systeme. Insbesondere die Popularität von Hardwarebeschreibungssprachen trägt da...

In this thesis an approach for the configuration of global networks is developed, to face new challenges posed by Industrie 4.0 and an increasing globalization. Industrie 4.0 leads to higher autonomy and self-organization of single supply chain processes. Globalization causes an increasing fragmentation und worldwide scattering of supply chain units. Until now, decisions for configuration are often enforced by strategic directions on a network level. However, the arrangement of the network st...

The aim of this paper is to present a boundary-layer analysis of two-phase dusty non-Newtonian fluid flow along a vertical surface by using a modified power-law viscosity model. This investigation particularly reports the flow behavior of spherical particles suspended in the non-Newtonian fluid. The governing equations are transformed into nonconserved form and then solved straightforwardly by implicit finite difference method. The numerical results of rate of heat transfer, rate of shea...

Developing optimizing source-level transformations, consists of numerous non-trivial subtasks. Besides identifying actual optimization goals within a particular target-platform and compiler setup, the actual implementation is a tedious, error-prone and often recurring work. Providing appropriate support for this development work is a challenging task. Defining and implementing a well-suited target-platform description which can be used by a wide set of optimization techniques while being prec...

Diese Dissertation unternimmt es, ganz im Sinne Droysens, den Klosterplan ‚aus seiner Zeit‘, d. h. dem frühen neunten Jahrhundert, und ‚aus sich selbst‘, d. h. seiner materiellen Überlieferung heraus zu verstehen. Das Nachzeichnen des Kultur- und Wis- senshorizonts in den karolingischen Klöstern zu jener Zeit führte im Wesentlichen zu den Ergebnissen, daß der Klosterplan ohne Hilfsgitter entstanden ist, er weder religiö- se Reformvorstellungen (Aniane) noch benediktinische Klosterregeln (RB) ...

A viscous damage model including two damage variables - a local and a nonlocal one - coupled through a penalty term is investigated on three different levels: unique solvability, behaviour as the penalization parameter approaches ∞ and optimal control. Existence, uniqueness and regularity of the solutions are proven. In particular, we give an improved result regarding spacial regularity of the nonlocal damage. Lipschitz continuity as well as Fréchet-differentiability of the solution operato...

Durch die vielfältigen technischen Anwendungsmöglichkeiten mikroverkapselter Systeme besteht ein stetiges Interesse an neuartigen Grenzflächen- und Membranfilmen, die eine effektive Stabilisierung von Emulsionstropfen ermöglichen. Im Rahmen dieser Dissertation wurden erstmals temporär vernetzte Mikrokapseln entwickelt, charakterisiert und ihr Verhalten in externen Zentrifugal- und Scherfeldern untersucht. Im Vordergrund stand dabei der Vergleich zweier unterschiedlicher Substanzklassen, Sorbi...

Electron spins in semiconductors are considered as candidates for quantum bits. This thesis presents a study of the spin dynamics of the strongly localized donor-bound electrons in fluorine-doped ZnSe epilayers via pump-probe Kerr rotation technique. A method exploiting the spin inertia is developed and used to measure the longitudinal spin relaxation time (T1). The excitation of the same samples with helicity-modulated laser pulses results in a transverse nuclear spin polarization, which was...

In this article, we present a-posteriori error estimations in context of optimal control of contact problems; in particular of Signorini’s problem. Due to the contact side-condition, the solution operator of the underlying variational inequality is not differentiable, yet we want to apply Newton’s method. Therefore, the non-smooth problem is regularized by penalization and afterwards discretized by finite elements. We derive optimality systems for the regularized formulation in the continuous...

The consistency of a bootstrap or resampling scheme is classically validated by weak convergence of conditional laws. However, when working with stochastic processes in the space of bounded functions and their weak convergence in the Hoffmann-Jorgensen sense, an obstacle occurs: due to possible non-measurability, neither laws nor conditional laws are well-defined. Starting from an equivalent formulation of weak convergence based on the bounded Lipschitz metric, a classical circumvent is to fo...

The block maxima method in extreme value theory consists of fitting an extreme value distribution to a sample of block maxima extracted from a time series. Traditionally, the maxima are taken over disjoint blocks of observations. Alternatively, the blocks can be chosen to slide through the observation period, yielding a larger number of overlapping blocks. Inference based on sliding blocks is found to be more efficient than inference based on disjoint blocks. The asymptotic variance of the m...
