Modem for powerline communication
Sláčik, Ján ; Mlýnek, Petr (referee) ; Kolka, Zdeněk (advisor)
This bachelor thesis is dealing with the standards and usable circuits applications for a powerline communication, which are currently available. Principle of this kind of communication is described for default supply network 230 V/50 Hz. This work is also describing several available modems which can be used for this type of communication. The properties of the standards PRIME and the G3-PLC, which are presently at disposal, are specified, measured and compared with each other in this project. The concentrator based on the G3-PLC standard extended about radio interface was designed. Afterwards this device was tested in various topologies and interference scenarios. The graphical interfaces, which allow the transfer measurements in multiple modes are described is this work as well. The entire measurements were realized in a real conditions for both tested modems. The results of these measurements are validating the purpose of each standard and its configuration.

High Data Rate Narrowband PLC Communication based on OFDM
Csiba, Patrik ; Herencsár, Norbert (referee) ; Mlýnek, Petr (advisor)
This bachelor project is about narrowband PLC communication. In this project is described history, principle of narrowband communication and description of four available narrowband standards (PRIME, G3-PLC, G.hnem, IEEE P1901.2) with their comparisons. In the next part are described the experimental measurements, that are performed in home environment with use of the TMDSPLCKIT modems from the Texas Instruments company, MT39-L1-ver.R modems from the ModemTec company and EVALKITST7580-1 modems from the STMicroelectronics company.

Hierarchical Techniques in Lighting Computation
Ligmajer, Jiří ; Polok, Lukáš (referee) ; Navrátil, Jan (advisor)
This master thesis deals with description of hierarchical techniques in global lighting computation. Here is explaining the importance of hierarchical techniques in lighting computation and shows method, how to use these hierarchical techniques in realtime radiosity and its extension to dynamic area lighting. These two techniques are described in detail in the first part of this project. In the other part is desing and implementation of application for dynamic area lighting computation.

Narrowband PLC communication based on G3-PLC, PRIME and IEEE-1901.2 standards
Skrášek, Tomáš ; Šilhavý, Pavel (referee) ; Mlýnek, Petr (advisor)
Diploma thesis is about narrowband PLC communication standards. The theoretical part describes details of all available OFDM standards including G3-PLC, PRIME, IEEE-1901.2 and G.hnem. The practical part deals with PRIME and G3-PLC standards. In this part is also compared OFDM technology with system of single carrier frequency in environment with real interferences. The last part describes developement of two firmwares for PLC modems Texas Instruments TMDSPLCKIT-V3, which allow UART communication and remote data collection. The thesis also includes Windows application developed to display and save collected data.

Electronic control units of present SI-engines
Michna, Lukáš ; Beran, Martin (referee) ; Dundálek, Radim (advisor)
Bachelor’s thesis named „Electronic control units of present SI-engines” treats of presently known and extended electronic control systems of SI-engines, so those ones, who mainly control both fuel-air mixture preparing and its ignition in combustion chamber. These are two fundamental functions for engine running, so they are described in light of basic principle of operation and also in light of each kind of these systems and its developmental stage description. Next point is enumeration and description of single parts of electronic control system participating in engine controlling, separated to logic sections. The end of publication makes reader acquainted with most extended types of electronic control systems, their producers and elementary differences.

The use of Computers in the Number Theory
Konečný, Zdeněk ; Karásek, Jiří (referee) ; Skula, Ladislav (advisor)
PARI/GP is a relatively obscure mathematical software that was designed especially for quick calculations in the number theory, but which has also found its application in other areas of mathematics. This work gives an overview of the basic commands of PARI/GP, and some simple examples to show their potential use. PARI/GP is then used for looking for large primes of special forms.

The influence of foreign direct investment on the development of competitiveness of the Czech economy
Zenáhlík, Aleš ; Plchová, Božena (advisor) ; Nigrinová, Lenka (referee)
The aim of this work is to prove or refute the impact of FDI on the competitiveness of the Czech Republic compared to its primary competitors, the countries of the European Union and the OECD. The work is divided into two sections. The theoretical section lays the necessary groundwork and explains the importance of the observed indicators and the impact of FDI on the host economy. The practical section is further divided into two subsections dedicated to an econometric analysis of the selected quantitative and qualitative indicators respectively. Their dependence on FDI is assessed using linear regression model. The results of this work should serve as an argument for the increase or limitation of the promotion of FDI inflows into the Czech Republic.

Regional and Structural Impacts of FDI
Mazánková, Ester ; Štěňhová, Božena (advisor) ; Korandová, Jiřina (referee)
Cílem diplomové práce je zhodnocení regionálních a strukturálních dopadů PZI na Českou republiku. Snahou je zaprvé vysvětlit všeobecná východiska PZI a popsat faktory ovlivňující příliv zahraničního kapitálu do České republiky vůbec a také regionálně. Za druhé zhodnotit příliv zahraničního kapitálu s důrazem na jeho strukturu, a to jak z pohledu teritoriálního, tak z pohledu odvětvového. Na konec je uvedena analýza dopadů PZI v aplikaci na Moravskoslezský region.
