Secure converter for an RS-232 standard to the Internet
Pokorný, Michal ; Mlýnek, Petr (referee) ; Koutný, Martin (advisor)
Master´s thesis tries to find a solution to make a secure transmission channel between virtual serial ports on the personal computer and the serial ports on the Rabbit RCM3700 development KIT. Today’s communications channels don't offer appropriate security of a whole communication. Therefore it depends on get-togethers, in order to realize this security themselves. This security means ensuring reliable transmission of data to be encrypted between parties so that any attacker is not able to read real-time, or eventually change them. As a result of this Master thesis is the design and implementation, which in addition to encryption algorithm provides sufficient security and authenticity of communication between the parties. As an encryption algorithm has been chosen widely used AES algorithm and as authentication algorithm has been chosen algorithm, which for authenticity requires knowledge of the secret key.

Automotive antenna for mobile communications
Porč, Jan ; Láčík, Jaroslav (referee) ; Pokorný, Michal (advisor)
This thesis deals with design of flush–mounted planar disc antenna suitable for use in vehicles. For each of the bands GSM900 and GSM1800, which are used in Czech republic, an independent antenna has been created. As a simulator of the electromagnetic field the program IE3D has been used. For the improvement of theoretical results an optimisation in the program MATLAB has been developed. As the optimisation method the genetic algorithms have been selected.

Can the Economics Explore the Animal Behavior?
Pokorný, Michal ; Lipka, David (advisor) ; Minárik, Pavol (referee)
The purpose of this work is to answer the basic question, if the economics can explore the animal behaviour. At first the determination of the subject of economics is needed. It means to point out, what should economics deal with. I will come to the point of the problem of purposeful action, the problem of rationality and exchange. Consequently I will explore, if it is possible to apply this theory to animal behaviour and if such an application has a sense. I will advert to the problems, what are made by the economists in their opinions of the animal behaviour and on argumentation why the animal behaviour is not a subject of economics.

Fixní měnový kurz
Pokorný, Michal ; Ryvolová, Ivana (advisor) ; Řežábek, Pavel (referee)
Práce má za cíl posoudit smysl volby fixního kurzu v současnosti. Prostřednictvím teoretických poznatků zhodnotit, zda je fixní kurz vhodnější než flexibilní kurz, případně za jakých okolností. Toto srovnání vychází ze zhodnocení dopadů volby fixního kurzu na reálnou ekonomiku, zda jsou tyto dopady spíše negativní nebo pozitivní. Aplikace těchto poznatků v praktické části je zaměřena na transformující se ekonomiky střední, východní Evropy a Pobaltských zemí v období mezi lety 1990 ? 1995. V případě Litvy je toto srovnání až do současnosti, protože důsledky se lépe posuzují při delším časovém období.
