Secure, reliable and adaptive network based on Cisco devices
Lefler, Přemysl ; Komosný, Dan (referee) ; Kubánková, Anna (advisor)
This bachelor thesis deals with design of secure, reliable and adaptive network using Cisco network devices. Thesis includes design of a network with description of each individual technology, that were used in the design to meet requirements for safety, reliability and adaptivity. The last chapter describes frequently occuring network attacks along with a description of their execution followed by implementation of defense against them.

Human reliability assessment
Kučera, David ; Kotek, Luboš (referee) ; Mukhametzianova, Leisan (advisor)
This master’s thesis aims to analyze the possibilities of failure of human reliability on the example of an induction heater from company Roboterm spol. s.r.o. in Chotěboř. The objective of a thesis is a review of a literature of human reliability assessment. Based on the analysis of the operation and a literature review and choose the appropriate method to perform the actual assessment of the reliability of human error. Final object of the work is to propose measures to increase human reliability.

Reliability of Technical Systems
Jirgl, Miroslav ; Šedivá, Soňa (referee) ; Havlíková, Marie (advisor)
This thesis deals with a reliability of technical systems. It is divided into four main parts. The first part deals with the mathematical description of reliability. Probability and statistics are used for this description. This part includes the definition and properties of random events, the description of discrete and continuous random variable and its distribution. The second part contains the definition and expression of reliability, types of faults in the digital circuits and the reliability of electronic components. This part introduces into problems of reliability. The third part includes making the reliability diagrams and reliability analysis. Each method is briefly described here. Further advantages and disadvantages of using each method are given here. The two most widely used reliability analysis - Failure Mode and Effect Analysis - FMEA (resp. FMECA) and Fault Tree Analysis – FTA are described in a greater detail. The last part focuses on an example of calculation of reliability. An analyzed object is Universal Charger NiMH and NiCd batteries. Reliability is analysed by block diagram, FTA and FMEA.

Mining Multiple Level Association Rules
Nguyenová, Thanh Lam ; Burget, Radek (referee) ; Bartík, Vladimír (advisor)
This bachelor thesis deals with multiple level association rules mining. The aim of this work is to focus on available algorithms for mining multiple level association rules and to implement an application with a graphical user interface that will demonstrate the functionality of these algorithms. Five algorithms based on the Apriori algorithm were chosen. Experiments with each algorithm were performed using the application and the results were compared and evaluated at the end of the thesis.

Haptic Feedback System and its Reliability
Horpatzká, Michaela ; Hlinka, Jiří (referee) ; Janhuba, Luboš (advisor)
This master thesis covers conceptual design of haptic feedback system and safety and reliability assessment. System is developed for aircraft categories UL2, EASA CS-LSA, EASA CS-VLA and EASA-CS-23. Conceptual design is divided into three parts. First is aimed on haptic system test with simulator. Second is conceptual design of haptic system for in-flight test. Third part contains safety and reliability assessment and summarizes problems of haptic system installation in real aircraft.

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.

Indirect aircraft control systems
Kalný, Jan ; Trefilová, Helena (referee) ; Třetina, Karel (advisor)
Bachelor's thesis is concerned with the description of selected elements in aircraft control systems and their integration into the aforementioned systems. Included with this concern are regulatory requirements for system reliability. Further work is focused on contemporary trends in the development of modern aircraft control systems. The final section consists of aircraft statistical surveys by use of aircraft control systems.

Stochastic analysis of shear failure of reinforced concrete beams
Kucek, Martin ; Doležel, Jiří (referee) ; Novák, Drahomír (advisor)
The diploma thesis is focused on a solution of the load reaction of the bridge construction from girders KA-73. Proposal methods of the nonlinear analysis by means of final elements on the stochastic and deterministic level are used for the solution of the load reaction. A simulation technique Latin Hypercube Sampling is used within the stochastic analysis. A material degradation in the form of the trussing corrosion is solved with the expected decrease of the construction lifetime. The conclusion of the thesis contains an evaluation of initial quantities of material parameters for the load reaction of the construction in the form of the sensitivity analysis.
