Construction of Reliability Models for Advanced Digital Systems
Wanka, Mario ; Drábek, Vladimír (referee) ; Kaštil, Jan (advisor)
The goal of this thesis is to simulate the impact of reliability of circuits designed to detect failures in components of advanced digital systems. At first the reliability and terms related are defined and Markov models are itroduced. These are used as logic for simulator, which is introduced in next chapter. This simulator is an ad-hoc solution and it's usage is thoughly described, as well as it's bahviour in various situations and configurations. In the end the results of experiments with reliability of circuits designed to detect failures for multiple models are shown and discussed. By the results of this thesis it is obvious, that the crutial factor for system's reliability ensurance is failure disguis in short-term view and repairing ability in long-term view.

Construction of Reliability Models for Advanced Digital Systems
Trávníček, Jan ; Drábek, Vladimír (referee) ; Kaštil, Jan (advisor)
This thesis deals with the systems reliability. At First, there is discussed the concept of reliability itself and its indicators, which can specifically express reliability. The second chapter describes the different kinds of reliability models for simple and complex systems. It further describes the basic methods for construction of reliability models. The fourth chapter is devoted to a very important Markov models. Markov models are very powerful and complex model for calculating the reliability of advanced systems. Their suitability is explained here for recovered systems, which may contain absorption states. The next chapter describes the standby redundancy. Discusses the advantages and disadvantages of static, dynamic and hybrid standby. There is described the influence of different load levels on the service life. The sixth chapter is devoted to the implementation, description of the application and description of the input file in XML format. There are discussed the results obtaining in experimental calculations.

Network data traffic analysis and modeling
Šabatka, Zdeněk ; Molnár, Karol (referee) ; Růčka, Lukáš (advisor)
This bachelor's thesis is focused on analysis of network traffic and its modeling. In the thesis, there are described various methods of traffic modeling, both current and modern, and historical, for contemporary traffic inconvenient. The first part is focused on the theoretical analysis of these models, there are also mentioned basis formulas. In the second part, practical, there is capcured real WWW traffic. In the last part, that real network traffic is modeled using Markov model.

Dopady metody tvorby a zúčtování opravných položek banky na její hospodaření
Pečinková, Lucie
The diploma thesis deals with the creation of loans provisions in banks. The need for adjustments is based on the existence of credit risk and this thesis presents techniques of credit risk measurement and applied credit risk indicators. Before calculating provisions, it is necessary to classify receivables, whose parameters are also discussed in the thesis. The practical part focuses on methods of calculating provisions. The method of coefficients, discounted cash flow method and statistical methods are compared. Markov model and gross roll rate model were selected from statistical methods. The findings were evaluated and recommendations were made based on the findings.

Pharmacoeconomical analysis of multiple sclerosis in the Czech Republic
Grishko, Anna ; Sobíšek, Lukáš (advisor) ; Zouhar, Jan (referee)
Pharmacoeconomics is an interdisciplinary scientific field that serves to guide optimal health care resource allocation. Pharmacoeconomics evaluates costs and effects of pharmaceutical products. Conclusions from pharmacoeconomical studies are used as a basis in the process of registering new medicines, pricing and reimbursement of new and already registered medicines. In addition, such studies are also important for health insurers, patient organizations and doctors. Besides evaluating financial costs, pharmacoeconomical studies evaluate non-financial outcomes, for example, effects on the patient's quality of life. The aim of this bachelor thesis is to applicate Continuous-Time Markov Model on clinical data of patients with multiple sclerosis in Czech Republic. In this thesis, disease progression models for two distinct groups of patients are compared. The disability progression in multiple sclerosis affects the costs of illness and increases the overall economic burden of disease. One of the goals of this study is to find out whether early treatment with disease modifying drugs is able to delay progression to functional disability. Furthermore, the research of papers and literature on multiple sclerosis and pharmacoeconomics was carried out.
