Modeling and simulation of the electric motor control
Kečkéš, Adam ; Pohl, Lukáš (referee) ; Bartík, Ondřej (advisor)
The aim of this bachelor's thesis is to study the issues of modeling three-phase electric motors and subsequently to create a suitable motor model in the d,q coordinates. The thesis outlines the issues related to controlling three-phase motors, based on which the Six-step and Vector control algorithms are implemented and analyzed. A simulation demonstrating closed-loop control with a suitable algorithm is created for the prepared motor model in the d,q coordinates. Subsequently, a suitable state feedback controller is implemented. The final part of the thesis consists of analyzing nonlinearities such as friction and dead zone.

Portrayal of d/Deaf People in Cinematography
Švábová, Adéla ; Zbořilová, Radka (advisor) ; Prokšová, Hana (referee)
The bachelor's thesis analyzes the topic of deaf people and deafness in feature-length motion pictures made by hearing directors. At the beginning of this thesis the author focuses on the terminology concerning deaf people, the relationship between art and deaf people and deafness, brief history of cinematography with the accent on important events concerning deaf people and deafness and then the author focuses on influence of movies on public opinion with the accent on terms stereotype, prototype and myth. Author afterwards focuses on analysis of the selected sample of movies. There are two types of analysis in this thesis, first one looks into purpose of the topic in those movies, the second one analyzes chosen movies in detail. The second analysis ends with comparison and evaluation of those movies. The purpose of this thesis is to make first insight into the topic of deaf and deafness in feature-length motion pictures made by hearing directors.

Source-Code Migration Using Decompilation
Korec, Tomáš ; Ďurfina, Lukáš (referee) ; Zemek, Petr (advisor)
This thesis deals with source-code migration of high-level programming languages using decompilation. A migration tool developed within the thesis is built on top of the middle-end and back-end parts of Lissom project decompiler. Several compilers generating LLVM IR code from input languages are discussed. Compilers suitable for integration to the migration tool were chosen. Compiled LLVM IR code is an input of the decompiler's optimizing middle-end. The output from the migration tool is a code in the C language or Python-like language generated by the back-end of the decompiler. The input languages are Fortran and its dialects, C/C++/Objective-C/Objective-C++, and D. The thesis describes problems connected with migration of these languages, their solutions, and ways to improve quality and readability of the produced source code.
