Workplace               470 - Department of Applied Mathematics

Thesis language        English

Description               In engineering practice, contact boundary conditions can be encountered wherever you go, and there are several software packages, both commercial and academic, which allow these problems to be solved. An important problem, which needs to be addressed prior to solving contact problems is the very identification of contact edges/boundaries or surfaces of bodies, which are considered in the given problem. In this dissertation, the student will become familiar with problems of mechanics, which consider contact boundary conditions, description of contact boundaries for similar and dissimilar meshes (Mortary, the InterNodes method) and notably with methods which are provisionally known for identification of contacts. Upon the study of the so far published methods and algorithms, the student will choose the most optimal method for its implementation in Matlab followed by its implementation in the PERMON software package. The resulting implementation will be tested on a series of real problems.

Supervisor               doc. Ing. Martin Čermák, Ph.D.

Workplace               470 - Department of Applied Mathematics

Thesis language        English

Description               Problems of elastoplasticity are non-linear problems, which have been solved for several decades, and its scope has been increasingly extending along with increasing precision of computations. In numerical computations, the finite element method with linear and quadratic elements is predominantly applied. The problems of elastoplasticity have recently started to be also solved using mixed finite element methods, which allow us to solve problems which were at least problematic to be solved using finite element methods. The student will become familiar with elastoplastic problems, classical and mixed finite element methods, and methods for solving non-linear problems as well as with state-of-the-art solutions of elastoplastic problems and finite element methods. At the beginning, plane-stress elastoplasticity will be addressed using Matlab with its further extension. The resulting efficient implementation will be programmed into the PERMON software package.

Cost-based Optimalization of Relational Database Queries

Supervisor               doc. Ing. Radim Bača, Ph.D.

Workplace               460 - Department of Computer Science

Thesis language        English

Description               The query optimizer is one of the critical relational database components. The optimizer looks for the cheapest plan for an input SQL query. The possibilities of query optimizer can be significantly improved, despite the decades of research and development, since they perform poorly even for simple SQL queries. The selected query plan is dependent on a query syntax even though the SQL language is declarative. The reason for such a situation is a general design of the query optimizers and a large number of possible query plans for a typical SQL query. Development of approaches allowing more straightforward query optimization is still an open problem.

Supervisor               doc. Ing. Radim Bača, Ph.D.

Workplace                460 - Department of Computer Science

Thesis language        English

Description               The graph is appropriate for the modelling of many nowadays problems. Searching of the shortest path or calculating centrality of a vertex represent typical graph operations. There are also less known problems, such as finding a path in a graph based on a regular expression. The problem of these operations on large graphs is their high temporal or spatial complexity. The ideal would be to find a solution that is a compromise between the two extremes. Alternatively, we might want to use the parameter to set the ratio between the spatial and temporal complexity of these operations. A solution with such characteristics is still an open problem.

Thesis language        English

Description               Round robin tournaments are represented using 1-factorizations of complete graphs. There are classical scheduling techniques, describing which teams will meet in which round. Yet, scheduling real life tournaments poses additional requirements that are not met by the classical scheduling techniques. Moreover, incomplete tournament can have further nice properties balancing difficulty for teams of different strength. In 2014 the number of different 1-fatorizarions for 14 vertices (teams) was established using a supercomputer, there is 10^18 such non-isomorphic 1-factorizations. To find the best schedule using brute force traversing all 1-factorizations for 16 or more tams seem not possible. Yet, 1-fatorizations on a limited set can be examined. The goal of this thesis is the theoretical analysis of 1-factoriations with further requirements as well as a parallelized search for such factorizations with restrictions.

Description               This dissertation is focused on SMART street lighting system for power quality monitoring from the perspective of adaptive current control strategy for three-phase shunt active power filters. Nowadays, under the pressure of so-called SMART city concept, demands are placed on power efficiency and consumption reductions. Extended SMART functionalities, such as intelligent management systems, sensorics, electromobility, security or even entertainment are slowly expanding conventional solutions. The concept of SMART Street Lighting apart from its intended illumination functionality provides other technologies, such as internet connectivity or various sensors. These SMART light sources are operating 24/7, which cause instabilities in power grid and influence power quality. The number of higher current harmonics increase significantly, thus causing a number of problems. This dissertation primarily focuses on testing of adaptive system (using adaptive filtration) on real measured data from BROADBANDLIGHT SMART testing polygon. This polygon consists of various SMART technologies, such as camera systems, sensorics systems, charging stands, entertainment systems, parking assistance systems or even communication systems.
