Tools for Executable File Format Conversions
Matula, Peter ; Husár, Adam (referee) ; Hruška, Tomáš (advisor)
This paper describes methods and procedures used for object file format conversions. It introduces several commonly used formats (ELF, PE, E32Image, DEX) and project Lissom's object file format (LOFF). It contains basic information about libraries manipulating these formats and a description of a new library managing E32Image. The primary objective is to implement a program converting files between common formats and LOFF. This problem is solved by mapping all critical information from one format structures to another. To accomplish this task, it was necessary to modify and extend some features of Lissom object format. The result is the plugin based application capable of creating valid and runnable executable files in mentioned formats.

Measurement of HV equipments by electronic bridge.
Kumičák, Ivan ; Pelikán, Luděk (referee) ; Krbal, Michal (advisor)
The main idea of this thesis is measurements of dielectric materials by using a device Tettex. The thesis is about basic physic properties of dielectric materials. The determination of a dielectric material is considered. The behavior of these materials in electrical fields and reasons, those can have an influence on it, are considered as well. In the text are described measuring methods of chosen parameters of dielectric materials by device Tettex and its functional principles. There are an evaluation of measurements, which were done, and a discussion about achieved results.

Decompilation from Selected Object File Formats
Bandzi, Michal ; Láznička, Stanislav (referee) ; Matula, Peter (advisor)
Object files contain machine code that can be executed by processor unit. Structure of an object file is defined by its file format. In order to decompile an object file, it is necessary to process and convert file data to internal representation of decompiler. This thesis discusses design and implementation of new modules for file format processing that will be part of the Retargetable Decompiler project. The goal of this work is to add support for Intel HEX and Mach-O file formats and new implementation of already supported Portable Executable file format. Implementation of modules for file formats Intel HEX and Mach-O was successful and it is possible to use them for reverse compilation. Processing of PE file format is not possible in sufficient quality due to errors in used LLVM library.

Improving Extraction of Information From Executable Files
Hájek, Karel ; Kolář, Dušan (referee) ; Zobal, Lukáš (advisor)
This thesis deals with extension of an open-source decompiler project called RetDec maintained by the Avast company. The goal is to develop an extension of data extraction from executable files for malware analysis improvement. The thesis proposes several possible improvements on data extraction in the RetDec project. The most useful of these suggested enhancements are then selected and implemented. The selected enhancements involve calculating a hash of symbol names in Linux executable files and a more extensive analysis of Authenticode format, a Microsoft technology for digital signing of executable files for Windows operating systems. The thesis implements the selected additional data extractions in the RetDec project and tests them on real-world malware samples.

Testing of polymeric materials under climatic conditions of Antarctica
Mičkal, Petr ; Sluková, Michaela (referee) ; Krmíček, Lukáš (advisor)
The bachelor's thesis generally deals with polymer materials and evaluates the possibility of testing their resistance to extreme climates of Antarctica. Described herein are various polymer materials, their characteristics, structure, properties and more thorough and detailed descriptions of selected polymers. The next section describes the basic types of degradation these polymers are exposed to, when facing the extreme conditions of the Antarctic climate. The practical part contains evaluations of tests made on the degraded polymer materials that were collected in Antarctica during the southern Antarctic season of 2013-2014 by Ing. Bc. Pavel Kapler, Ph.D, who is a superintendent at the Czech scientific station JG Mendel.

Influence of detergents on the accelarated lifetime tests of PE pipes grades.
Štolfová, Kristýna ; Přikryl, Zdeněk (referee) ; Nezbedová, Eva (advisor)
This thesis studies the lifetime of the PE pipes materials. For determination of the lifetime one of the standard accelerated tests (Full Notch Creep test) was used. The main goal is to assess the influence of different types of detergents on lifetime. Specimen preparation and measurement procedure corresponding to the relevant ISO standard (ISO 16770: Plastics - Determination of environmental stress cracking (ESC) of Polyethylene (PE) - Full Notch Creep Test (FNCT)). Air, distilled water, Arkopal N 090 and Arkopal N 110 were used as detergents.

Level of motor abilities of primary school children dealing with ballroom dancing
Jinochová, Tereza ; Hájková, Jana (advisor) ; Hronzová, Marie (referee)
The aim of this dissertation is to find out the level of motoric abilities at younger school age children who take part in social dance. I tested the level of motoric abilities using the test battery Unifittest (6 - 60). I compared the level of motoric abilities at younger school age children who take part in social dance and at younger school age children who only attend PE lessons. I tried to find out the change of the level in motoric abilities at the two above mentioned groups. I also tried to discover the type and frequency of other sport activities which children regularly do in their free time. Empirically focused part of my thesis substantiate that children of the younger school age, who take part in social dance, achieved a bigger improvement of fitness and coordinative motoric abilities. The biggest improvement was in the test of flexibility. On the basis of the questionnaire survey I found out, that children of the younger school age who do not take part in social dance, very often devote to football in their leisure. KEYWORDS younger school age, motoric abilities, social dance, PE, Unifittest (6 - 60)

Mapping the occurrence of teaching martial activities in PE at primary schools and grammar schools in Prague
Sochor, Jakub ; Zdobinský, Adam (advisor) ; Pavelka, Radim (referee)
Title: Mapping the occurrence of teaching martial arts in physical education at primary schools, secondary schools and grammar schools in Prague. Objective: The goal of the research is to find out how education in P.E. classes reflects the recommendation of framework education programme about education of martial arts, what percentage of clasśes do martial arts take in P.E. and to describe current trends of implementing martial arts to the curriculum or discover the reasons behind not implementing from the P.E. teacher's perspective. Methods: Analysis of literature of the given topic. We chose a survey as a research instrument. Based on previously published survey, which asked about the education of martial arts at a smaller selection of schools in Moravian region (Reguli, Ďurech, Vít, 2007), we created a purposeful survey. The survey was made on a platform service survio.com and distributed via e-mail to individual headmasters. They passed on the survey to P.E. teachers Results: Based on the evaluation of the survey, it was found that 75 of 84 teachers involve combat activities in P.E. classes. Of all of the questioned, 48 respondents were men and 34 women. Most of our respondents were between 31-40 years old. Most respondents teach only at E.P.A., 48 in total. Falling techniques are included by...
