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.

Abstract The thesis deals with the issue of oil exploitation companies and their impact on conflict in Sudan between the north and the south. In Sudan, the resurrection of civil war in 1983 corresponded with the oil dicovery on the borderlands between the two countries and oil has played important role also in the question of recent secession of South Sudan in January 2011 and reocurrence of violence between the two countries. The multi-national oil extraction companies are the carriers of oil money to the government so the thesis was examinig their impact on the conflict through the resources they provide the government with, the leverage they might have on the government and also direct impact on local communities. The conclusion was that the impact is negative and the capacities the companies have to influence it in positive way, are highly unexploited. Secondary research aim of the thesis was to understand the factors determining the behavior of the companies through their firm-specific intersts, relationship with the Government...

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.

Contemporary Terrorism in Ethiopia: its Origin and Motivation
Nováček, Pavel ; Werkman, Kateřina (advisor) ; Michalek, Tomáš (referee)
Résumé of the master thesis: Contemporary Terrorism in Ethiopia: its Origins and Motivation. Pavel Nováček This paper focuses on the factor of terrorism in Ethiopia. There is suspicion, repeatedly declared by the Ethiopian government, that there are groups operating on its territory, that are using terrorism as a method of combat. Some of those groups are suspected to be affiliated to the global jihadist network that is active in the neighbouring Somalia. Ethiopia takes an active part in the US-led war on terror, and is the most important ally of the US in the region. This has resulted in a flow of humanitarian aid to Ethiopia, and the US is also providing military training, building their counter-terrorism capacities and providing Ethiopia with analytical support and other military aid. However, there is suspicion that Ethiopia is abusing its participation in the war on terrorism in order to oppress the legitimate opposition, by describing some of the rebel groups as terrorist, and even as affiliated to the global jihadist network in Somalia. This is despite the possibility that these ethnic based groups might be legitimately fighting to gain the right of self- determination, something that is granted to all people living in Ethiopia by the constitution. The government however, systematically attacks the...

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....

Valuation of an agricultural company
Michálek, Tomáš ; Hricová, Daniela (advisor) ; Olga, Olga (referee)
The topic of this master thesis is a valuation of an agricultural company. Based on this valuation, an objective value of the company is obtained which might serve as a suitable knowledge before selling or buying the company. Two appropriate methods were chosen for valuation. Their choice depended on collected information about the company and on the results of a preliminary strategical and financial analysis.
The thesis contains two parts. In the first one, results of a literature search are given encompassing the key notions in the valuation process, available preliminary analyses, methods and recommended processes of valuation.
The second part puts the theory into practice using an existing company. First, the financial and strategical analysis is implemented. Depending on the results of the analyses, it is decided whether to evaluate the company and if so, which methods to choose for valuation. Finally, two appropriate methods of valuation are chosen the method of book value and the method of capitalized net earnings. The results of these two methods are combined in the final value. The rest of the work contains the final conclusion.
