Modern CAD Systems in Power Engineering
Strnad, Karel ; Vorel, Pavel (referee) ; Kuchyňková, Hana (advisor)
This work is focused on the short summary of history CAD systems and there are described the news, which brings the new version of programme Autodesk Inventor compared to the previous one. Then, in five steps there is described the procedure of parametric modelling in the programme Autodesk Inventor, from the sketch to final 3D model, including the drawing documentation. The work put particular emphasis on the explanation the basic modelling functions and environment in the same programme. An important part of this work is also the short explanation of some concepts relating to parametric modelling and animation of the model created in programme Autodesk Inventor.

Application for Generating of School Schedules
Fiala, Jan ; Horáček, Jan (referee) ; Rozman, Jaroslav (advisor)
This work deals with problem of generating school schedules. The solution is based on three heuristic algorithms (hill-climbing, simulated annealing, genetic algorithm) and is fully implemented in JAVA. It provides a comparison of implemented heuristic algorithms including description of their pros and cons.

Optimization of prestress tendon path
Středulová, Monika ; Lehký, David (referee) ; Eliáš, Jan (advisor)
The thesis explores possibilities of applying genetic algorithms on the problem of finding the optimal prestressed concrete tendon path. The objective of the thesis is to develop a genetic algorithm based on the Automatic Dynamic Penalization method and to test its robustness on selected analytical functions. Subsequently, the algorithm is connected to a Time Dependent Analysis module for the computation of prestressed concrete structure to solve selected examples of prestressed beams in the form of a constrained optimization problem. The algorithm is developed in the Python programming language with the help of the Distributed Evolutionary Algorithm library.

Asynchronous communication interfaces in FPGA
Cabal, Jakub ; Fujcik, Lukáš (referee) ; Bohrn, Marek (advisor)
The aim of this thesis is to analyze the options for implementation of asynchronous modules for clock domain crossing in an FPGA circuit. Such crossings are inevitable in moderately complex firmware designs and can lead to data corruption or loss, if implemented incorrectly. Furthermore, the work deals with application of correct constraints. The practical part of this work describes an implemented library of clock domain crossing modules. Further, the practical part describes a created methodology for use of clock domain crossing modules, whose application is demonstrated in a case study of a network interface card circuit created for the acceleration card COMBO-80G.

Toolbox for multi-objective optimization
Marek, Martin ; Hurák,, Zdeněk (referee) ; Kadlec, Petr (advisor)
This paper deals with multi-objective optimization problems (MOOP). It is explained, what solutions in multi-objetive search space are optimal and how are optimal (non-dominated) solutions found in the set of feasible solutions. Afterwards, principles of NSGA-II, MOPSO and GDE3 algorithms are described. In the following chapters, benchmark metrics and problems are introduced. In the last part of this paper, all the three algorithms are compared based on several benchmark metrics.

MS SQL Application Development Framework
Hanes, Marek ; Kopecký, Michal (advisor) ; Hoksza, David (referee)
Title: MS SQL Application Development Framework Author: Bc. Marek Hanes Department: Department of Software Engineering Supervisor: RNDr. Michal Kopecký, Ph.D. Supervisor's e-mail address: kopecky@ksi.mff.cuni.cz Abstract: The thesis deals with a database application development and tries to find ways to optimize the most common problems encountered. The goal of this thesis is to design and develop a modular framework that simplifies the database application development and prevents inexperienced users from using unsafe SQL statements and/or expressions. The example of such a statement can be the insert statement without explicit column list, unsafe XPath expression, etc. The framework provides among others manipulation with history tables allowing versioning of data and reverting unwanted data changes asynchronous and parallel SQL execution support, error management and logging support, monitoring of schema changes as well as procedure and function debugging Together with means of data manipulation, the framework provides the simple way of publishing stored procedure as web service as well. The framework is accompanied by well-written programmers and users guide to allow its further development. Keywords: application development, framework, modular design, safe statements, constraints 1

Role of evolutional mechanisms in designing of acoustic signals
Rulfová, Alena ; Policht, Richard (advisor) ; Linhart, Pavel (referee)
Acoustic communication is a wide-spread phenomen in all animal taxones. The theme of evolutional mechanisms and their functioning in acoustic communication has become more and more frequently studied during last years, and geographic variation in acoustic signals has been reported in various taxa such as insect, birds, anurans and mammals. However, some evolutional mechanism still remain poorly understood. The mechanisms comprise mainly stochastics forces such as genetic drift and bottleneck or cultural drift. Genetic drift causes stochastic changes in acoustic signals, whereas bottleneck probably primarily spawns reduction of acoustic variability. Some acoustic parameters are shaped by habitat and others by species' phylogeny. Physical environment and other ecological factors play important role in shaping vocalizations in most species, and thus distantly related populations occupying similar habitats may possess very simmilar vocalization. Because of that, revealing phylogenetic pattern is possible only by careful cladistic analysis of vocal characters in taxa that have simple songs or calls that are not learned, and whose habitat distributions are well understood. By finding the proper acoustic parameters we can also e.g. map connection between acoustic divergence and glaciations, history of colonisation...

Search Strategies for Scheduling Problems
Kypta, Tomáš ; Barták, Roman (advisor) ; Čepek, Ondřej (referee)
In the present work I compare the search strategies for solving scheduling problems from the view of constraint programming. The thesis is focused on scheduling problems containing alternative activities. An analysis of previously published various ways of modelling the problems is provided, next description and experimental comparison of search strategies targetting these models is provided. The influence of strategies on the speed of the solver is studied primarily. As a sideeffect the work studies the ways how Choco solver, which was utililized for implementation of the experiments, can be used to solve the scheduling problems with alternative activities.
