Simulation of Entities Collective Behavior in Virtual World
Vymazal, Tomáš ; Žák, Pavel (referee) ; Láník, Aleš (advisor)
Theme of this work is to evaluate and compare aviable paradigms for entity control in virtual worlds, and to implement one of these paradigms in application. Dynamic finite state machine upgraded using genetic algorithms has been chosen. This paradigm should make agent's behavior better and adapt agent to required state: i.e. make agent harvest resources in virtual world. Output of this work is application for running evolution and application for 3D view of agent's behavior.

Development of high-strength concrete defined properties with the use of secondary raw materials
Ondráček, Michal ; Vítek,, Jan (referee) ; Ďurica,, Tibor (referee) ; Vymazal, Tomáš (referee) ; Hela, Rudolf (advisor)
Civil engineering development is connected with the application of new construction methods and the development of new building materials. Concrete, as one of the basic building materials, is part of this development. A major turning point in the development of concrete and its properties occurred with the use of new, more efficient plasticizing additives. This allowed to produce concrete with lower water cement ratio, while increasing the strength of concrete. Gradually, the compressive strength of concrete boundary has moved by several levels, when there are currently commonly used concrete with strength of about 100 N/mm2 and with the special methods of concrete production strength range from 250 to 300 N/mm2. A negative aspect of the development of (ultra) high-strength concrete is their energy and economic demands. A characteristic feature of high-strength concrete is a high content of cement and very fine admixtures, especially silica fume. One way to improve the economics of these types of concrete is the application of cheaper admixture based on industrial waste. The content of this work is the observation and description of the properties of high-strength concrete and reactive powder concrete, in which the admixtures were based on industrial waste were applied. Part of this work is the comparison of economic parameters for individual types of concrete.

Risk analysis and evaluation in building foundations design
Kalenda, Lukáš ; Bednářová, Bronislava (referee) ; Vymazal, Tomáš (advisor)
This diploma thesis deals with the analysis and evaluation of quality, environmental and safety risks in the design process of the designing the foundations of building. The calculation procedure is shown in the model example. Subsequently, the risk analysis according to DIN EN 31010: 2011 Risk Management - Risk Assessment Techniques is performed. The risk assessment was made by following methods: analysis of the causes and consequences (Ishikawa diagram), the risk matrix and Analysis Failure Modes and Effects (FMEA). Using these methods, the risk were identified and assessed. There are also proposed appropriate measures to reduce the risk value. Comparisons with publications with a similar theme is performed in the final summary.

Effectiveness evaluation of occupational safety and health management in civil engineering in the Czech Republic
Kratina, Zdeněk ; Bednářová, Bronislava (referee) ; Vymazal, Tomáš (advisor)
Thesis deals with the development of risk management in the construction industry in Czech republic in time of the economic crisis since 2007. There is in detail described the present and paste state of the construction industry in this thesis, thanks to construction output index, the volume of construction output, etc. There is overview of accidents and deaths in costuction industry, history of risk management in the construction industry and the main reasones of injuries and deaths in the construction industry described in this thesis. The aim of this thesis is to inform about development and efectiveness of risk management and evaluate work injuries in construction industry with the assumption further development.

Risk analysis and evaluation of using automated systems in building construction design
Koza, Josef ; Bednářová, Bronislava (referee) ; Vymazal, Tomáš (advisor)
This thesis in its first part deals with the complexity of the legislation, which is related to design activities and also trying to explain the basic rules for the creation of project documentation. In the main section then analyzes and evaluates the selected drawing software in defined categories. Based on the selection chooses the best drawing software and compared with the hand-crafted version of the design documentation in terms of time and cost. The final time for the creation of project documentation will be converted to a built-up area of the building and found the relationship between time constraints and the size of the built-up area of the new building. It will also be evaluating the return on investment to drawing software and assessing cost-effectiveness of various options drawing. The aim of this thesis is to analyze the risks in the use of software products for structural design and evaluate their use based on the value of work.

Risk analysis and evaluation of sources of public water supply
Novotná, Aneta ; Bednářová, Bronislava (referee) ; Vymazal, Tomáš (advisor)
The thesis is focused on the identification, quantification and assessment of risks in the supply of drinking water, the application of appropriate methods for specific public water supply, the environment and operation. WaterRisk method based on EN 31010 Risk Management - Techniques of risk assessment methods are chosen - analysis of possible defects and their consequences (FMEA), Pareto diagram and Ishikawa diagram. The aim of the thesis is analyze and assess the quality, environmental and safety risks to the public water supply system and use tools for their management and elimination. The results will be compared and evaluated the advantages and disadvantages of each analysis.

Risk analysis of building design with regard to the selected material characteristics
Jirásková, Iveta ; Vymazal, Tomáš (referee) ; Misák, Petr (advisor)
This thesis focuses on the verification of physical and mechanical characteristics of hardened concrete, especially concrete compressive strength, static and dynamic modulus of elasticity. The job description is to perform a series of laboratory analyzes for structural concrete and evaluate the test results meet requirements that are specified in the European standards for designing buildings. The work also includes selected techniques for risk assessment (FMEA, Pareto diagram, Ishikawa diagram) and their application to selected process. Part of the work is also a static comparison of measured characteristics and consideration of the risks associated with variations in the monitored quantities.

Using fuzzy clustering in modelling of hardened concrete properties
Haluska, Lukáš ; Vymazal, Tomáš (referee) ; Misák, Petr (advisor)
Compressive strength is one of the most monitored parameter of hardened concrete and it is usually determinated by destructive testing. Non-destructive testing applied on existing constructions uses regression analysis to estimate compressive strength. High variability of outputs and eventually failure of necessary requirements for using regression analysis complicate these methods. The aim of this thesis is to show posibility of using fuzzy clustering in this topic and to compare outputs with classic methods.
