Risk assessment design margin of process and power equipment
Horsák, Jan ; Pačíska, Tomáš (referee) ; Jegla, Zdeněk (advisor)
This work is devoted to description of methodology of determining process and power equipment design margins, which is based on assessment of a relative process importance of the equipment in question. The methodology is theoretically analysed, brought into context of common design practice and demonstrated on actual cases. Substantial part of this work analyses heat transfer in general as a base of heat exchanger design process.

Enhancement of Probabilistic Methods for Password Cracking
Lištiak, Filip ; Polčák, Libor (referee) ; Hranický, Radek (advisor)
This thesis describes passwords cracking using probabilistic context-free grammars, specifically PCFG Cracker tool. The aim of the thesis is to design and implement enhancements to this tool, which reduce the size of output dictionaries while maintaining acceptable success rate. This work also solves critical parts in the tool that slow down the overall duration of the program. Another goal of the thesis is to analyze and implement targeted attack dictionaries that increase the scope and success rate of generated passwords.

Construction Order Risk Management
Saňáková, Miroslava ; Sukup, Miroslav (referee) ; Waldhans, Miloš (advisor)
The subject of the bachelor thesis is the issue of risk management in the construction company. The first part of the thesis is based on the terminology used and the interpretation of the relevant terms. Here we can find the classification of risks from different angles of view, possible division and classification of risks. Then there is a focus on significant sources of risk and on those involved in construction that are affected by the risks. The fourth chapter is to familiarize with the different stages of the risk management process, including the introduction of selected methods and techniques that are commonly used. The theoretical part is the basis for the fifth chapter, which summarizes the problems of the risks of a particular construction company and two of their construction orders.

Performance comparison of methods for design of experiments for analysis of tasks involving random variables
Martinásková, Magdalena ; Novák, Drahomír (referee) ; Vořechovský, Miroslav (advisor)
The thesis presents methods and criteria for creation and optimization of design of computer experiments. Using the core of a program Freet the optimized designs were created by combination of these methods and criteria. Then, the suitability of the designs for statistical analysis of the tasks vith input random variables was assessed by comparison of the obtained results of six selected functions and the exact (analytically obtained) solutions. Basic theory, definitions of the evaluated functions, description of the setting of optimization and the discussion of the obtained results, including recommendations related to identified weaknesses of certain designs, are presented. The thesis also contains a description of an application that was created to display the results.

Management of water reservoir storage function using methods of artificial intelligence
Urbanec, Patrik ; Matoušek, Petr (referee) ; Kozel, Tomáš (advisor)
The subject of this thesis is to control the storage function of the reservoir using artificial intelligence methods, including the construction of the appropriate control algorithm. The thesis is divided into the theoretical part and the part of the application of reservoir storage function control. The theoretical part describes the control algorithm and the prediction model. The following are basic optimization methods and artificial intelligence methods. The second part presents the historical data used for the prediction model. The following is a description of calibration and validation of the control module and evaluation of the application results. Finally, there is a comparison and summary of individual results, control algorithm and prediction model. According to the results, the control algorithm can be recommended for further investigation.

Risk Process Evaluation
Jakab, Robert ; Ráb, Jaroslav (referee) ; Marušinec, Jaromír (advisor)
The first part of my work is focused on technology of Oracle. Here are mentioned individual languages, which works with data and different data types. Here is made clear manner, how are data saved in the database. Next I described technology of Apollo, on which information system Apollo is build. Next part of my work is analyze, in which is described present state of evaluation risk process and requests, which are layed on this module. Following chapter is implementation. There are described both database schema and by detail parts of module in a form of strips. Here is at large interpreted the way how to value risk and risk process. This chapter contains print reports for this module as well. The next chapter is dedicated to how module was brought to functioning. Except making this module running in information system Apollo is here a chapter about education of employees. In the closure I present evaluation of reached results, show next development and present my own benefit.

Implementation of KDE+ statistic method
Svoboda, Tomáš ; Popela, Pavel (referee) ; Bíl,, Michal (advisor)
In this master's thesis I presented a new statistical method KDE+ (Kernel Density Estimation plus) that allows detecting clusters of points on the linear data. I created a self-standing application that enables anybody to try the method and apply it on their own data. One possible usage of the method and application is for the detection of critical roads sections with a high concentration of traffic accidents. Development of the application includes analysis of KDE+ statistical method, design of appropriate program structures and the implementation. Optimization were carried out to achieve higher performance after creating the prototype. At the end the software was validated by analysing vehicle collision data from the police database of the Czech Republic.

Non-standard application tasks and problems
PRŮDKOVÁ, Kamila
The bachelor thesis deals with non-standard application tasks and problems in mathematics. The aim was to create a collection of tasks with their sample solution using the computer program GeoGebra for interactive geometry, algebra, and analysis. In addition to the content of tasks and their sample solution in text form, the result of this work is an online output in the form of a GeoGebra book. The above-mentioned multiplatform dynamic software GeoGebra can be recommended for teaching, visualization, solution, and analysis of tasks in mathematics.

Selected aspects of diagnostics of the reinforced concrete structure of the interwar period of the 20th century
Žítt, Petr ; Bílek,, Vlastimil (referee) ; Pěnčík, Jan (referee) ; Daněk, Petr (advisor)
The dissertation deals with diagnostics and load tests of a reinforced concrete ceiling structure built in the interwar period of the 20th century. The theoretical part of the work is an excerpt from standard regulations for the design of structures in terms of material properties of concrete and reinforcement, the implementation of load tests and measuring equipment used. Furthermore, static calculations according to relevant standards, numerical and stochastic analysis of selected members. The practical part of the work is then focused on performing experimental load tests of selected elements of the ceiling structure with appropriate diagnostic work, which includes determining the geometry of the supporting structure, reinforcement of elements and determining the quality of built-in materials. An integral part of the practical part of the work is based on the data obtained from the performed load tests and diagnostic work to perform a static assessment of the affected structures and to compile a deterministic and stochastic FEM model of the selected member. The conclusion is a comparison of measured data with FEM analyzes, analysis of the justification of the use a load tests in the context of classical diagnostic methods and the methodology of the optimal number of test samples for objective evaluation of the actual state of the structure.
