AVR microprocessor implementation on FPGA
Hájek, Radek ; Dvořák, Vojtěch (referee) ; Pristach, Marián (advisor)
This bachelor‘s thesis deals with FPGA implementation of Atmel AVR core described using VHDL language. Basic architecture concepts and processor addressing modes are summarized in this thesis. The core including several peripherals was designed to be compatible with ATtiny26 architecture and instruction set. The microprocessor was described in VHDL and verified in several types of tests.

Determination of organic substances in tar formed after biomass combustion and gasification
Hájek, Radek ; Mravcová, Ludmila (referee) ; Vávrová, Milada (advisor)
Biomass pyrolysis and gasification techniques count among basic technological procedures for its use as a source of energy. As a side-effect, production of tar can be considered. Tar is a complex mixture of various organic compounds and affects negatively both the environment and the facilities where biomass is processed. Within the scope of this master thesis the analysis of tar samples from different materials was performed. As an appropriate analytical method the gas chromatography combined with flame ionization detection (GC-FID) and time-of-flight mass spectrometry (GC-TOF-MS) was chosen. The concentrations of volatile organic compounds known as BTEX, polycyclic aromatic hydrocarbons (PAH) and phenolic compounds were assessed.

MicroBlaze processor implementation using CodAL language
Hájek, Radek ; Zachariášová, Marcela (referee) ; Pristach, Marián (advisor)
The diploma thesis contains theoretical basis, classification and function of processors. It summarizes the principle of pipelined instruction processing and the types of hazards in the microarchitecture of the processor. It also introduces design of processors using CodAL language developed by Codasip company. In the practical part of the thesis the model of MicroBlaze core developed by Xilinx company was described in the CodAL language. Designed model was tested and implemented into the FPGA device as practical example.

Assessment of drugs in settlings with waste water treatment
Hájek, Radek ; Mravcová, Ludmila (referee) ; Vávrová, Milada (advisor)
This bachelor thesis is focused on asessment of pharmaceuticals in wastewater treatment plant sludge. Two macrolide antibiotics (erythromycin and clarithromycin) and three non-steroidal anti-inflammatory drugs (ibuprofen, naproxen and diclofenac) were assessed. Sample of sludge was taken in municipal wastewater treatment plant in Brno-Modřice. Analytes were obtained using pressurized solvent extraction (PSE) or ultrasonic solvent extraction (USE). Clean-up was performed by solid phase extraction (SPE). Ultra high performance liquid chromatography followed by UV-VIS diode array detection was used for quantitative determination of the analytes.

Non-Volatile Memory Manager Unit For Spaceapplications
Hajek, Radek
The paper deals with HDL design methodology and methods of data protection against the influence of the Single Effect Upset (SEU) for the space applications. Presented methodology is applied to design of non-volatile memory manager unit, which is presented in this paper. This unit is responsible for transfer data between memories and must be fault-tolerant to the SEU. To ensure high reliability the data in the memories are protected by EDAC logic.
