Cryptanalysis of modern cryptographic devices
Fördős, András ; Člupek, Vlastimil (referee) ; Martinásek, Zdeněk (advisor)
The thesis focuses on power analysis of modern cryptographic modules. The first part contains a brief introduction to the topic of the power side channel and basic methods of analyzes. The text describes the process of comparison of modules and a short description of devices found. In the practical part two modules has been selected for the implementation of the encryption algorithm AES-128. The first module was the chip card Gemalto .NET v2 and the second one was the Raspberry Pi. A workplace has been created for these modules which allowed to measure the power consumption of the algorithm AES. Differential Power Analysis has been made using the captured results. In its conclusion the work presents the results in tables and samples of source codes. Graphs were made from the results captured on the Raspberry Pi and from the results of the Differential Power Analysis.

This Master's thesis is dealing with elementary analysis of milk. Theoretical part describes general characteristics, terminology with basic legislature and classification of milk. Large part is focused on chemical composition, especially on description of mineral substances selected for analysis in experimental part of this thesis. Choices of elementary analysis and preparation of samples for ICP-OES method conducted by other authors are also mentioned. Specification of emission spectrometry with inductively coupled plasma is crucial, a technique used for purposes of this dissertation. Experimental part deals with preparation of samples, approach of analysis and processing of measured results. The aim of this part is to compare concentration of analyzed elements in different kinds of milk. Samples from 15 different kinds of milk were used for analysis, which were determined by ICP-OES method. Results were compared to each other in discussion as well as with results from other authors.

During monitoring three tests were made that supplied input, control and output data.T-test method for pair values ofdepending selections was used to process and analyze obtained data. Results: Results show to instructors of the tested group the control over the training and doing the particular volleyball activity, methods oftraining and the technical improvement of the team. The after comparison of boys and girls shows the speciality of the motoric progress in this age. Keywords: Keywords Volleyball Playing activity of an individua! Volleyball ofthe youth Training - 5 -

Balance-related exercise as a preparation to cross-country skiing practice in visually impaired children
Chmelíčková, Hana ; Daďová, Klára (advisor) ; Levitová, Andrea (referee)
Title: Balance-related excercise as a preparation to cross-country skiing practice in visually impaired children. Objectives of the Thesis: The goal of this thesis is to test the possibilitiy of implementation of selected balance- related excercise in visually impaired children. Method: The testing pool consisted of six pupils attending the Special school for Visually Impaired Children between 14 and 15 years of age. Over the period of ten weeks, selected exercise geared towards the cross-country skiing was practiced with these students. The research method applied to measure students' indicators of balance before and after the excercise was an assessment of standing stability at the Footscan pressure table, as well as a walking test in terrain with blinded eyes. Results and Conclusions: This research has indicated the possibility of physical intervention in form of balance- related practice as part of the preparation before the cross-country skiing season begins. It has proven that selected balance-related excercise can be applied with no limitations during the physical education classes for visually impaired pupils. After the physical intervention, the majority of tested individuals showed improvements in their indicators of dynamic balance, as proved by the walking test in terrain with blinded...

Use of technical analysis when trading on futures markets
Boháček, Daniel Martin ; Smrčka, Luboš (advisor) ; Zámečník, Petr (referee)
This bachelor's thesis deals with the topic of stock exchange transactions, deals with use and application of elements of technical analysis in trading on commodity (futures) markets. The reader of this thesis becomes gradually acquainted with stock markets, basic market principles and methods, by which it is today possible to successfully trade on commodity markets. The theoretical part simply takes the reader through some successive decisions like the selection of applied analysis, selection of the market, trading system and other aspects necessary for profitable trading. In the practical part of the thesis, I introduce a trading system by with it is possible to trade profitably while giving attention to all of it's rules. After a detailed description of all specific parts of the trading system, we come to an analysis MAE / MFE, which helps us to determine the position-exit strategy. In the chapter of backtest, we test the trading system on two futures markets, E-mini Nasdaq and E-mini Russell2000. At the end of the thesis, I try to use the trading system and trade with virtual money. I compare the results from backtest and papertrading, and i try to characterize the difference between these results.

Résumé Name of the Project: Conditional preparation of members of the Police of the Czech Republic The aim of the Project: The aim of this Project is to resume and to evaluate contemporary situation of conditional preparation and its testing applied to the members of the Police of the Czech Republic in the selected districts of the Central Bohemian Region. Methods: I have received information necessary for completion of my diploma work from research of available literature, law and other sources that deal with the given problem. I have analysed documents and evaluated obtained data (results of revisions) to confirm or rebut the specified hypothesis. Furthermore, I have questioned anonymously policemen in the selected districts of the Central Bohemian Region. Afterwards, I have evaluated the questionnaires and have resumed obtained data for final interpretation and final comparison and evaluation. Results: Discovered knowledge presents overall state and testing of conditional preparation and introduces opinions and attitudes of policemen towards conditional preparation. Key words: conditional preparation, physical fitness, movement abilities, motoric tests, lawful rules.

Separation of Azaarenes by High Performance Liguid Chromatography
Kočí, Kamila ; Friedl, Zdeněk (referee) ; Večeřa, Zbyněk (referee) ; Ventura, Karel (referee) ; Šimek, Zdeněk (advisor)
Under the framework of this PhD project, a study on chromatographic behaviour of selected azaarenes on octadecylsilica stationary phases during their separation by reversed phase liquid chromatography was developed. The main goal was aimed at an application of the basic RPLC principles on the retention behaviour of azaarenes including the effects such as peak tailing, peak broadening, irreproducible retention or strong retention on a stationary phase. This study was particularly focused on basic azaarenes, also called acridines, which belong to a group of persistent organic pollutants providing mutagenic and/or carcinogenic activity. The retention patterns were studied on a group of eight acridines that are often present in environmental samples polluted with polycyclic aromatic compounds. The mixture of acridines was separated under isocratic elution conditions on three octadecylsilica stationary phases using two different binary mixtures as a mobile phase. Evaluation of the surface properties of the selected stationary phases was firstly performed, followed by the separation experiments. The structure of the experiments was designed to evaluate the effect of three different factors on the retention behaviour of acridines: properties of a stationary phase, composition of a mobile phase and physical-chemical properties of acridines. The treatment of the results was based on the capacity factor values providing the best fitting and repeatability of data, but other parameters that evaluate thermodynamic and kinetic aspects of the separation process were also given. Simple correlations between the three factors and a character of retention mechanism of acridines on the given separation system were found. Application of this knowledge simplifies an optimisation process and helps to solve common separation problems for acridines, but also for other basic analytes displaying similar physical-chemical properties (Mr and pKa).
