X-ray beam hardening effect simulation
Milek, Jakub ; Kolář, Radim (referee) ; Drastich, Aleš (advisor)
At the beginning of this work the physics related background and it’s interaction with matter is described, followed by explanation of filters influence on X-ray spectrum. Linear attenuation coefficient is described and so are other related physical quantities. In the end the description of a simulator is presented.

Brand perception
VAŇKOVÁ, Veronika
The aim of this bachelor work was to analyze the perception of selected brands from the customer's perspective and from the perspective of brand founder called Regional Agrarian Chamber of the South Bohemian Region. To determine the attitudes of opinion on brand perception by the customer, I developed a questionnaire survey using semantic differential. First hypothesis, which argues that the selection of food plays an important role in regional mark at least half of the respondents, was refuted. Customers perceived the regionality as the most important criterion. The research showed that for respondents is very important high quality, but also the lower price and best evaluation are very important criterions for customers. Hypothesis number 2, which says that the brand owner CHJ has a more positive picture of the perceptions of customers than it is in reality, was confirmed. Founder CHJ brand has a positive idea of the perception of the brand, but the differences between this perception are not noticeable because of their own research, brand perception among its customers. When proposing to amend the emphasis was on increasing brand awareness. For this purpose, it was suggested to isme magazine in every three months. Consumers were presented by the newly awards manufacturers with their products. Distribution and financing was mainly doing by the Regional Chamber of Agriculture of the South Bohemia. In conclusion, the CHJ brand is not completely unknown in the eyes of the customer. It creates a certain image that customers perceive and which over time will become stronger and stronger. The fact that it really was so, they can make suggestions and recommendations given in this work.

High-speed data transmission in mobile and wireless networks
Rosenberg, Martin ; Martinásek, Zdeněk (referee) ; Mácha, Tomáš (advisor)
The goal of the master’s thesis was to propose two laboratory exercises, integrating newly purchased devices HTC Desire and Nokia N900. Designed tasks bring new technologies and services to education process. The first task examines the configuration of branch exchange Asterisk PBX and analyzes SIP protocol. Part of exercise is concentrated on high-speed data transmission in mobile and wireless networks, regarding to usability of VoIP technology. The second exercise introduces to vulnerability of VoIP technology. It contains simulations of attacks on branch exchange Asterisk, DoS attack and discusses methods to secure VoiP communication. The part of this exercise examines usage of HTC Desire phone, instead of ordinary Wi-Fi access point.

Banking Regulation: Assessment and Simulation of Regulatory Measures
Klinger, Tomáš ; Teplý, Petr (advisor) ; Jakubík, Petr (referee)
This thesis focuses on international banking regulation, particularly the capital adequacy requirements known as the Basel Accords. In the first part, we study the rationale for regulating the banks and describe the evolution of the Basel Accords, including the newly presented measures known as Basel III. The main conclusion of this part is that the regulation is heavily shaped by the banks themselves and does not always serve the best for protecting the financial system. In the second part dedicated to systemic risk modelling, we first introduce the used methodology and then build an agent-based model which enables us to simulate the impacts of various types of negative shocks given various settings of the banking system and the regulatory environment, including the capital and liquidity measures. Our simulations show firstly that sufficient capital buffers are crucial for systemic stability, secondly that the discretionary measures have little effect once a crisis breaks out and thirdly that liquidity measures are a relevant regulatory tool.

Feeding ecology of bats in the Mediterranean
Žďárská, Lenka ; Benda, Petr (advisor) ; Andreas, Michal (referee)
My work concerns the review of feeding strategy and ecology in bats of the Mediterranean. The aim was to provide an overview of food and feeding habits of bat species of the family Vespertilionidae inhabiting the Mediterranean region. First, there is a description of the geography, climate and biodiversity of the Mediterranean. Furthermore, there are described feeding strategies of particuar bat species in connection with the morphological structure of their bodies. The main part represents an overview of bat species in connection with their food. As it turned out, in some species, especially in the newly differentiated and/or endemic (Pipistrellus hanaki, Plecotus sardus, Plecotus teneriffae, etc.), there is a lack of any reference to their food or feeding strategy, on the other hand, there are species which are of considerable interest and for which a lot of data exists (Pipistrellus pipistrellus, Plecotus auritus, Barbastella barbastellus, etc.).

Modeling the Mach's principle in the post-Minkowskian approximation to general relativity
Schmidt, Tibor ; Ledvinka, Tomáš (advisor) ; Kofroň, David (referee)
The aim of this thesis is the simulation of relativistic phenomena in post- Minkowskian approximation. In the introduction the terms of Mach principle and gravitomagnetism are presented. Afterwards the principles of numeric solution of ordinary differential equations are summarized. Consequently, we get acquainted with the first post-Minkowskian approximation in canonical formalism and with elementary examples of its use. In the next chapter the results of performed simulations of classical General Relativity tests are described. The last chapter is devoted to the simulation of gravitomagnetism and of the system of rotating particles.

Ethnicity, Territoriality, and Conflict in the South Caucasus - A Qualitative Comparative Analysis
Chernyaeva, Maria ; Aslan, Emil (advisor) ; Šír, Jan (referee)
Under what configuration of conditions do ethno-territorial conflicts escalate, and under what configurations of conditions is conflict avoided between a minority and the centre in multi- ethnic states? This dissertation employs qualitative comparative analysis (QCA) in order to capture the causal patterns of conflict escalation and peace preservation. By simultaneously analysing the causes of conflict and the conditions of peace, this dissertation bridges a significant gap in the existing literature that assumes causal linearity and unifinality. The QCA analysis this dissertation conducts is grounded in empirical evidence from the South Caucasus where, after the disintegration of the Soviet Union, three newly independent states emerged and grappled with the accommodation of ethnic-minorities and their evolving identities. The QCA analysis reveals that, contrary to the popular premise that regional autonomy is "an effective antidote" for ethno-territorial wars, autonomy in the South Caucasus was conducive to conflict and the lack of autonomy was conducive to peace. Nevertheless, this dissertation does not suggest that autonomy on its own can explain the complexity of inter-ethnic relations. Rather, it argues that there were multiple configurations of conditions that interacted to produce...
