Various File Systems Used on Different Storage Devices
Bortlová, Pavlína ; Krčma, Martin (referee) ; Lojda, Jakub (advisor)
The bachelor thesis deals with storing data on various storage devices, namely on the HDD, SSD, flash drives, SD cards. In the teoretical part are discussed principles of functions storage media and data storage structure through various file system. In the practical part was measured read and write speeds selected combinations of file systems (FAT, NTFS, XFS, ext4, btrfs, exFAT, JFFS, F2FS) and storage devices (HDD, SSD, flash drive, sd card).

The content of basic analytical constituents in selected raw meat
URBAN, Martin
This work is focused on the pork meat analysis. The moisture, fat, protein, collagen parts content in pork ham, shoulder and loin were measured with the NIR-method using. The samples from Masokombinát Plzen presented a high moisture content in comparison with the lower fat content. In the opposite the samples from Slaughterhouse contains a higher level of fat and less water. The pork ham purchased from the Slaughterhouse Lisov comprised 66.20 %, respectively 71.65 %, respectively 72.99 % moisture. Pork ham from the manufacturer Masokombinát Plzen contained 74.28 %, respectively, 75.18 %, respectively, 73.84 % moisture. The fat content of pork ham from manufacturer Slaughterhouse Lisov was measured 12.27 %, respectively, 4.55 %, respectively. 3.96 %. Pork ham from the manufacturer Masokombinát Plzen contained 1.76 %, respectively, 2.06 %, respectively, 3.01 % fat. The highest humidity of 75.29 % was measured at the pork shoulder by Masokombinát Plzen. At least moisture contained pork ham purchased from the manufacturer Slaughterhouse Lisov (66.2 %). Analysis revealed a high fat content of 12.03 % by the pork shoulders manufacturer Slaughterhouse Lisov. At least 1.76 % fat contained pork ham producer Masokombinát Plzen. Content of protein was the highest in pork ham by Slaughterhouse Lisov 24.13 %. Content of only 18.34 % of the protein was measured at the pork shoulder by Libor Novak. Most parts of the collagen contained pork loin from Slaughterhouse Lisov 1.78 %. Content of 0.4 % collagen parts were the lowest measured value. The highest moisture content (75.29 %) was measured at the pork shoulder producer Masokombinát Plzen, at least contained a pork ham from Slaughterhouse Lisov (66.2 %), the highest fat content (12.03 %) was observed in the pork shoulder from the manufacturer Slaughterhouse Lisov, the least fat (1.76 %) contained pork ham from Masokombinát Plzen. The richest content of proteins was in pork ham producer Slaughterhouse Lisov (24.13 %), only 18.34 % of the protein was measured at the pork shoulder of the company Libor Novak. The most of the collagen contained in sample from pork loin from Slaughterhouse Lisov (1.78 %) and the lowest in pork leg (0.32 %) from the manufacturer Masokombinát Plzen.

The content of basic analytical constituents in selected meat products
KŘIVÁKOVÁ, Tereza
The aim of this study was to assess selected analytical values (water content, fat, protein, collagen and salt parts) in chosen meat products ( at least 50 pieces of product) using NIR methods. There were chosen five kinds of meat product as a studying material ham sausage ("špekáček"), sausage ("vídeňský párek"), salami ("gothajský salám"), salami ("vysočina"), bacon ("anglická slanina") from ten different manufacturers from the Czech Republic. The results showed that "vysočina" was the most fatty and salty, with a maximum content of collagen and the smallest water content. "Vídeňský párek" contained the most water, but positively it was the least fatty and salty. "Gothajský salám" was evaluated as the lowest one within the quality because the results confirmed the lowest average of protein content. The smallest content of collagen was detected by "anglická slanina" and at the same time there was the maximum variability in water content, fat content , protein and collagen as well. The most negatively correlated water and fat.There exists extremely high dependence with "anglická slanina", "gothajský salám","špekáček" and this relation is presented as very high in statistical significance (p0,001). Similar results and statistical significance (p0,001) were detected between fat and protein with "anglická slanina".

Prototype of Outdoor Computer on STM32VL Discovery Platform
Leštach, Marek ; Orság, Filip (referee) ; Novotný, Tomáš (advisor)
This thesis focuses on describing of an outdoor computer prototype based on STM32VL Discovery platform and building it on the prototyping board. Prototype is able to locate itself with the help of GPS module and received data are recorded into connected MMC card formatted with the FAT filesystem. Information and trip statistics are displayed on a graphic display. Data on memory card are saved in NMEA-0183 format provided by the GPS module in order to be used with a map software on PC.

Forensic Analysis of Discs and Metadata under OS Linux
Kocnová, Jitka ; Rychlý, Marek (referee) ; Očenášek, Pavel (advisor)
This bachelor's thesis is about forensic analysis of memory devices and their metadata. It's part is also an application for Linux system which focuses on restoring data from memory devices using EXT, UDF and ISO 9660 file systems; and also some examples for educational use. The application was written in the C++ language and restores files by searching for their start and end tags. The application was tested on real data and it was also compared with already existing similar applications. As a result, it was found out that the application is successful even if there is no chance to work with informations stored in journal file of EXT file system, that is used by some of the other programs the application was compared with.

IDE Interface for HW/SW Platform FITkit
Sigmund, Stanislav ; Šimek, Václav (referee) ; Vašíček, Zdeněk (advisor)
This thesis deals with an implementation of IDE controller on FPGA unit and hard drive connection. Besides, a lot of library functions were created that provide basic control of a hard drive and make accessible file system FAT32. Proposed controller was designed for platform FITKit and to enlarge memory capacity of this kit.

GPS and Accelerometer Based Speedometer
Novotný, Tomáš ; Fiala, Jiří (referee) ; Orság, Filip (advisor)
This thesis deals with a design of speedometer for sportsmen, which is able to display current speed and to record a trip. The proposed parts are small enough. That's why sportsman won't be bothered much. The GPS is used for measurement of speed and to determine position. A strip, which consists of LED diodes, is used for speed displaying. The strip is situated in a sportsman's glasses. A trip is recorded to a MultiMediaCard. The FAT file system is used on the memory card.
