Of our main interest in this work is the stabilization of assemblies of topological defects (TDs) in liquid crystals (LCs). Due to the topological origin of TDs, the physics of defects is of interest for all branches of physics, including condensed matter systems, particle physics, and cosmology. LCs represent an …

The P-glycoprotein (P-gp) is responsible for the elimination of a wide variety of substances from the cell, thus it is thought to play an important role in detoxification functions. The P-gp also affects the ADMET (absorption, distribution, metabolism, excretion, and toxicity in pharmacokinetics) properties of drugs. It is involved in …

As urbanisation continues to be a trend, in which centralisation of the population into cities is still growing, the importance of intelligent solutions in mobility is in high demand. Likewise, with the integration of renewable energies into all levels of the electrical grid system and the increasing amount of heavy …

The task of mathematical modeling of dynamic systems from observed system behavior, widely known under the name of system identification, breaks down into two subtasks. The first task, referred to as structure identification, is to specify the model structure, i.e., the functional form of the model. In practice, the model …

In this thesis we demonstrate a new, simple, and ecient method for the solid-state synthesis of oxides with a complex chemical composition. We modify the traditional solidstate synthesis method, which is used in the majority of ceramics laboratories around the world, in order to prepare multi-metallic oxide powders from classic …

This dissertation addresses the problem of parameter estimation of stochastic, discrete-time, state-space models from input and output data. This class of problems can be found in many modern engineering applications, where the relationships in the real world processes have to be inferred from the observed data and available prior knowledge. …

We investigate the dynamics in one-dimensional (1D) and two dimensional (2D) mesoscopic superconductors in an external magnetic field using the time-dependent Ginzburg-Landau equations. We analyze the different transitions between metastable states and describe the creation of topological defects that occur as the phase of the Ginzburg-Landau order parameter makes finite …

In this doctoral thesis, radio signal propagation in special environments is discussed. The primary focus is on the development of a path loss model for radio signal propagation in long road tunnels and underground passageways, which allows a rather precise calculation of radio signal path loss and, consequently, a quick …

This work deals with the design of a small kitchen appliance with a weighing function integrated into a control loop in order to prevent unbalanced movement of the appliance during operation. In this particular case, the weighing should be appropriate for larger amounts (up to 5 kg) of ingredients. The …

The main purpose of this thesis is to describe the inhomogeneous phase of a layered system. The phase is the result of the competition between attractive interactions and the long range Coulomb repulsive force (LRCF). In order to achieve this, two different strategies are applied. The first is within the …
