Optimization of coupling between high-frequency generator and low pressure plasma
In this thesis we present the development of the device for the removal of carbon deposits in fusion reactors. Amorphous hydrogenated carbon deposits (a-C:H) represent a major problem for smooth operation of future fusion reactors with divertors containing carbon tiles, because they cause retention of radioactive tritium. There are techniques …
Parameter Identification in Nonlinear Dynamic Systems with Meta-heuristic Approaches
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 …
Model for Monitoring and Assessment of a Public Health Care Network
It is hard to imagine the management of any system without monitoring it as a process of continuously gathering data and performing real-time analyses. In general, monitoring can improve the estimation of the current state, optimization of the business processes, identification of the critical elements and new opportunities, and prediction …
Parallelization of an Evolutionary Algorithm for Multiobjective Optimization
Solving real-life optimization problems numerically is often very time demanding, because of high complexity of the simulations that are usually involved. Solving such problems becomes highly impractical for this reason and can even lead to use of less complex and also less accurate models. Fortunately, evolutionary algorithms, often used in …
Development of an alternative approach to membrane protein structure determination based on the analysis of local rotational conformational spaces
The problem of structure determination of membrane proteins is addressed with a new combination of site-directed spin labelling (SDSL) electron paramagnetic resonance (EPR) spectroscopy and structure modelling of a protein and its conformational spaces. This new approach is aimed at structural characterization of membrane proteins and intrinsically disordered proteins. In …
Stigmergy as an Approach to Metaheuristic Optimization
Developing metaheuristics to solve optimization problems is a rapidly growing field of research. This is due to the importance of optimization problems in the scientific as well as the industrial world. The methods developed in this dissertation are based on stigmergy: a method of communication in emergent systems, where the …
