Speed and position measurement using optical and electromagnetic methods
Dvořák, Zdeněk ; Říčný, Václav (referee) ; Kratochvíl, Tomáš (advisor)
The project compares and describes the characteristics of optical and electromagnetic methods, used for measuring the object’s velocity. Some of these are used at the ballistic laboratory of PROTOTYPA, a.s. company. The rest is mentioned in order to increase the range of the project and are not engaged by the company. The practical part involves measuring and processing the magnetic fields of various appliances. There is a method and appliance designed to process the link between flying object and sensor.

Development of high polymer grout system
Ručková, Kateřina ; Seidlová, Michaela (referee) ; Drochytka, Rostislav (advisor)
Bachelor thesis is focused on polymer grout, designed for heavy engineering operations and energy industry. The aim of the thesis is to define the requirements for use of polymer grout and also evaluation of testing procedures and legislative regulations on properties of these materials. Based on theoretical knowledge gained from literature will be designed HighTech polymer grout using secondary input materials.

Modern audio signal restoration methods
Kalník, Jan ; Mangová, Marie (referee) ; Rajmic, Pavel (advisor)
This bachelor thesis deals with modern methods of audio signal inpainting. Main methods used will be sparse signal representations. Those will be implemented into MATLAB software using LTFAT and UNLocBoX toolboxes. Next we would like to accomplish the best results with the audio inpainting and then compare these results as well as subjectively as objectively.

Basic measurement of bipolar and unipolar transistor
Kaňa, Leoš ; Šebesta, Jiří (referee) ; Dřínovský, Jiří (advisor)
In terms of the better effectiveness in the sphere of transistor characteristics measuring, no matter unipolar (FET) or bipolar (BJT), in laboratory conditions and their better understanding in terms of thrash out a subject matter is desirable have to available workplace let us say preparation enabling this kind of measuring with modifiability wiring and with possibility to change measured component. This thesis isn‘t focused only on development of this kind of universal component for measuring but simultaneously contains brief summary about the theory and parameters of transistors. Next aim is the development and realisation of static characteristic measuring program in VEE 8.0 Pro environment. Finally the complex laboratory exercise has to be done for measuring of bipolar and unipolar transistor’s static characteristics include programs for automatic measuring. For developing of DPS was used developing system named Eagle which gives us instrument with sufficiently accuracy. In thesis is contained theory needed for measuring and programming. Except possibility of measured component change we can change transistor connection in circuit on the board. This change is available for BJT (CE, CB, CC) and unipolar JFET (CS, CG, CD) transistor’s.

Genomic Data Mining Techniques
Jaša, Petr ; Křivka, Zbyněk (referee) ; Burgetová, Ivana (advisor)
First of all, this thesis sets itself a goal to introduce some common technics for datamining in genomics and as a next step to implement own algorithm like algorithm BLAST. In the concrete, this work is pointed to sequences of DNA. The DNA sequence contains in itself genetic information, which is template for living organism. For explanation this information can be used number of technics. This paper describes algorithm Fasta and algorithms from BLAST family. With these algorithms, it is possible to gain a lot of important information even about such DNA sequences, where only primary structure is known. Principle of these algorithms is based on alignments of one query sequence, which we want to obtain some information from, with many sequences stored in database. According to result alignment, it is possible to determine many features of the query sequence.

Alignment of DNA Parts
Pejř, Václav ; Burgetová, Ivana (referee) ; Rozman, Jaroslav (advisor)
This thesis deals with finding the possibilities within the sphere of alignment of DNA sequences. Based on these findings, the best solution should be found with regard to the quickness of computation and quality of alignment. Following this I intend to implement and thus create a functioning program that will do the alignment. The thesis starts with introducing issues dealing with biology, DNA and genetics. The introduction is followed by a survey of algorithms that are used for alignment, their evaluation and selection of the most appropriate algorithm for the implementation. The thesis also focuses on the usage of parallel programming by means of OpenCL libraries. The alignment is being done above many sequences at the same time, so that the methods how this process can be done and how to reach the best results are being examined.

Research and development grout and anchor masses
Žlebek, Tomáš ; Petránek, Vít (referee) ; Drochytka, Rostislav (advisor)
Modern anchor and grout systems are now at a high level and they are used in many branches of industry. This thesis evaluates the current state of anchoring and grouting systems, research of currently used material basis, testing procedures and up to date legislation for these types of materials. Above all, the thesis is focused on the chemical types of anchor and grout materials for utilization in industrial production facilities with exposure to extreme loads, a new methodology for testing of these types of materials and input raw materials will be proposed. The final part of this thesis is a proposal of new optimum formulas for anchoring and grouting materials for utilization in industrial production facilities with exposure to extreme loads including the description of their applications.

Expert System for Detection of Ventricular Extrasystoles
Svánovská, Zuzana ; Mézl, Martin (referee) ; Sekora, Jiří (advisor)
Ventricular premature beats are ectopic changes in the ECG signal. Detection of ventricular extrasystoles on 12leads ECG was created in MATLAB. At first my work involves whether the ventricular premature beats comes from the right or the left ventricle. Another algorithm evaluates the incidence outflow tract of the chamber. If the previous algorithm shows signs of indecision, another algorithm is used for detection of ventricular extrasystoles at another location in the left ventricle. The last step is to narrow the area of detection which makes it easier to find the place of origin.

The cost of carry model in stock index futures: theory and reality
Němcová, Marika ; Dědek, Oldřich (advisor) ; Kučera, Adam (referee)
The thesis investigates the pricing efficiency of the commonly used cost of carry model in pricing stock index futures and its applicability on the German blue-chip index DAX and related futures contracts in recent years. The work considers the deviations of the observed futures prices from their theoretical counterparts as well as the fitness of the model through regression analysis. The results show that while there are many deviations from the fair values suggested by the model these are small in magnitude when compared with the potential transaction costs implying the contracts are efficiently priced. It is confirmed that there is a cointegrating relationship between futures and spot index values, however, given the regression analysis results the prices do not entirely follow the model design. The other part of the analysis focuses on the behaviour of the basis throughout the life of the relevant futures contracts. The results suggest that there is indeed a decreasing tendency towards the expiration of a contract, nevertheless, it is subject to considerable fluctuations. The paper also documents other factors that might impact stock index futures prices yet not included in the standard pricing formula. JEL Classification C12, C14, C22, G13 Keywords stock index futures, futures pricing , cost of carry,...
