Effective random number generator for limited devices
Michálek, Tomáš ; Mlýnek, Petr (referee) ; Fujdiak, Radek (advisor)
This thesis solves the problem of generating random numbers on low-power devices. Author describes possible ways of generating and implements selected generators of (pseudo)random numbers on MSP430F5438A. 4 generators were added by the enhancement of one of them and a new generator was created, using the phenomenon of temperature change in the surroundings. For each generator, test sequences were generated and these sequences were tested by the Dieharder, STS-NIST, and Visual Test. The output of the thesis is the functional implementation of the generators, their testing by statistical methods and their comparison between each other.

Michálek, Tomáš ; Spáčilová, Jitka (referee) ; Brukner, Bohuslav (advisor)
This thesis addresses the six-storey newly built residential building with shops and underground garages. The apartment building has 80 residential units, four shops, a hairdresser and offices. The apartment house is designed as a combined column concrete skeleton with brick infill. In the underground garage there are 88 seats in the collator parking system. The building consists of a compact shape.

Detached house, Libcany
Michálek, Tomáš ; Kalábová, Tereza (referee) ; Bečkovský, David (advisor)
In the Bachelor's thesis is dealt with new above-standard modern family house. The object is placed on the free land that was previously used as a garden and orchard. The building is connected to the surrounding areas. The House is located in the village of the Hradec Králové region, in the Towns of p.p.č. 355/7. Built-up area object is 173,44 m2 Building has two floors. Roof of the House is composed of two flat roofs. The building is situated on gently sloping terrain. As the main building material was used a system of VELOX. The input part of the object is made up of an entrance, the entrance to which can be accessed from the garage. Area continues into the corridor, from which we get into stair Hall, study, which can also be used as a guest room, WC, bathroom and closet. From the stair Hall to go after the stairs to the 2nd floor, kitchenette with dining area, through which we get into spacious living rooms. From the living room, dining room and from the study can be accessed on the terrace and adjoining garden. At the entrance to the 2nd floor of cetrální Hall, a person can get in all the rooms. It comes to the bedroom, two children's rooms, technical room, closet, bathroom and toilet. The bedroom is a spacious dressing room and green terrace.

Secure communication in systems using restricted devices
Michálek, Tomáš ; Martinásek, Zdeněk (referee) ; Malina, Lukáš (advisor)
This thesis presents the usability and analysis of cryptographic methods on devices with low computing power and low memory capacity. The thesis describes different methods and shows examples of their usability in practice. According to certain parameters of security methods, such as code size and memory size it is selected and compared symetric ciphers and authentication codes. There are also described some security protocols and possible attacks. The next part includes a comparison of ciphers and chosen candidates are tested on our microcontroller. In the end there are propose, implemented and analyzed security protocols.

MAC Protocol for Wireless Sensor Networks
Michálek, Tomáš ; Krajsa, Ondřej (referee) ; Červenka, Vladimír (advisor)
The work focuses on introduction to the topic of wireless sensor networks and brings readers the various aspects of problem solving in these networks. Work is closely focused on the energy performance when communicating between devices on a network and discusses the causes of excessive energy consumption. It also addresses the mechanisms for saving energy and is also engaged today protocols that its contribution to proposing solutions to problems. The author had also proposes an adapted protocol, based on lessons learned from previous theoretical sources.

The result of direct aid: Masaka, Uganda
Ceryak, Elizabeth ; Michalek, Tomáš (advisor) ; Riegl, Martin (referee)
This paper is concerned with the efficiency of aid in Masaka, Uganda which is about 140 km from the capital city Kampala. It uses the results of 300 surveys and several interviews to gather data, and a causal methodology to define results. Much of the methodology is based on theories from William Easterly, Andrew Mwenda, Dambisa Moyo, Jeffrey Sachs, and Amartya Sen. It has been concluded that there are several problems in the Masaka area. One is Uganda's federal government, which is inefficient and unaccountable. There is also lack of easily accessible health care for rural citizens, and a lack of local development due to poor governance. Conversely, the residents of Masaka are quite developed in terms of employment and education, and have rated themselves as quite free and satisfied with life. There is also a quite adequate level of gender equality, especially in terms of education.

Congo War and Power Politics in Central Africa
Michalek, Tomáš ; Werkman, Kateřina (advisor) ; Ujfaluši, Marcel (referee)
The aim of this paper is to describe power in Central Africa in terms of actors and aspects. In order to find out who has the power and what it is like, the matrix of aims, strategies and results is used. The argument is that the state which is able to change aims into results has the power. Herein, it should be mentioned that the Congo conflict is not just one war; it is a complex of interrelated wars and disputes. Nevertheless, the analysis is centred at the state level of the conflict. The aspects of civil and local wars are neglected here; however, they cannot be totally ignored. At first, theoretical and historical backgrounds to the conflict are described. Here, the clientelism is central to very African system of power. Then, the politico-military, economic and diplomatic/intemational aspects of the second Congo war are analysed. The findings are that Angola due to its military strength and pragmatic aims is the main power in Central Africa. The second most powerful country in the region is Rwanda, whose military aims and strategies were, however, unfitted to its potential resources. These two states are able to control the African clientelism most accurately. On the other side, Uganda and Zimbabwe were not. In terms of other states, no one was able to influence the course of the second Congo war....
