Sound recording with a focus on education
DITRICH, Vít
This bachelor work deals with sound recording, especially with that of musical instruments. At first the physical qualities of sound, basic terms and the introduction to acoustics are explained. We will discuss sources of sound, how the sound comes up and in which way the musical instruments work. Furthermore we will solve the most used types of microphones and their correct and suitable application. We will focus on each musical instrument and on ways how to write down sound to be the best. Then we will clear up the sound processing, how the process of recording goes and its easy adjustment, which can be used in musical editors. We will finish looking at the possibilities of saving the records and which audio file formats are mainly used by musicians.

Format RAW and Its Utilization for Company Promotion
Sulanská, Tereza ; Šedivá, Zuzana (advisor) ; Sabolčák, Peter (referee)
RAW formats are becoming the new trend in digital photography. It is raw data which can be edited by the computer means. This way brings many advantages but also some disadvantages. Files are smaller than the TIFF format and do not lose quality like the JPEG format. Special software is necessary for editing and obtaining the highest quality images requires more time and practice. There are many programs for editing and converting RAW files on the market today, from the simplest freeware programs to the professional tools for several thousand crowns. This thesis deals with an explanation of all the advantages and disadvantages of RAW formats, describes and compares five RAW converters and a practical example demonstrates the possibility of special picture treatment methods.

Algorithm for Calculation of Radiation View Factors
Bílek, Tomáš ; Hlavička, Rudolf (referee) ; Čermák, Libor (advisor)
This thesis deals with a calculation of radiation view factors. The thesis includes mathematical model of the problem and its numerical solution. The main aim of the thesis is the creation of an algorithm for calculation of radiation view factors for given 3D geometries and its application for the heat flux analysis. CAD models of geometries, specified by a NASTRAN file format, are used as an input of the algorithm. Matrix of radiation view factors serves then as an output of the algorithm. The algorithm is programmed in MATLAB, but STAR-CCM+ is used for the NASTRAN specification of separate models. The algorithm is also designed for a computation on a computer cluster for cases of intricate geometries with consideration of shading areas.

Testing of Directional Earth Fault Protections Using The Experimentally Obtained Fault Records
Holub, Martin ; Topolánek, David (referee) ; Orságová, Jaroslava (advisor)
Master thesis Testing of Directional Earth Fault Protections Using the Experimentally Obtained Fault Records deals with the protective functions of earth fault protections during earth faults in compensated medium voltage distribution network and their testing options. At the beginning of the thesis we charakterize operation of medium voltage distribution system in general. We begin with definition and characteristics of earth fault and its compartmentalization by the type of the fault, size of the transition resistance and duration. We also mention grounding methods of node winding transformer on medium voltage distribution network and we describe the most common of them in detail, i.e. network grouded through the arc suppression coil and its operation with automatic switching auxiliary resistor. In this part of the thesis we discuss the localization of the earth fault using passive static methods in compensated systems, which include wattmetric, admittance and conductance method. In next section we deal with the fault records stored in COMTRADE file format, its structure and all elements of its configuration and data file. We create and describe an example of converting ADF file format, recorded by Yokogawa oscilloscope fault recorder, into COMTRADE file format using Microsoft Excel program and M-File created in the MATLAB program. In the practical part we introduce workspace devices and software, which includes secondary testing equipment OMICRON CMC 256plus and its software OMICRON Test Universe with Advance Transplay test module, we further describe multifunctional earth fault protection RYo from PROTECTION & CONSULTING, s. r. o. and machine terminal REM 543 from ABB and their protective functions. The last part describes the actual testing of parallel connected earth fault protection with COMTRADE fault records by Advance Transplay test module in the OMICRON Test Universe. In the conclusion we describe evaluation of the suitability of each protective functions of earth fault protection in a variety of sizes the transition resistance at the earth fault location.

Differential Gene expression using a negative binomial model
Janáková, Tereza ; Tkacz, Ewaryst (referee) ; Abo Khayal, Layal (advisor)
Hlavním cílem této diplomové práce je analýza diferenciální exprese genů na základě negativního binomického modelu. Úvodní část je věnována teoretickému základu, pojednává o sekvenování RNA, sekvenování nové generace, výhodách a možném využití, formátu fastQ aj. Následující část už se zabývá samotnou praktickou částí, zde byl vybrán vhodný set genů, které budou později analyzovány a příslušná data byla stažena. Tato data byla zarovnána k lidskému genomu verze 37 Burrowsovou-Wheelerovou transformací s využitím bowtie mapovače, byly tak vytvořeny soubory ve formátu SAM. Toto soubory dat byly později setříděny pomocí nástroje SAMtools. Následně byly v programovém prostředí Matlab (verze R2013b) vytvořeny anotované objekty genů s využitím služby Ensembl´s BioMart. Dále byla určena genová exprese a byly odhadnuty faktory velikosti knihovny. Na závěr byly odhadnuty parametry negativního binomického rozložení a byla vyhodnocena diferenciální exprese genů.
