Composition of Municipal Waste
Straka, David ; Musilová, Petra (referee) ; Elbl, Patrik (advisor)
This bachelor thesis deals with the composition of municipal and mixed municipal waste. Introduction of the research part deals with the composition and properties of waste. In the next section, the waste is considered as fuel and compared with conventional solid fuels. The conculusion of the research part is devoted to the research of the waste composition from selected incinerators adn foreign countries. The compulational part of the thesis deals with the determation of energy properties of the waste.

A Tool for Post-Mortem Debugging
Kapičák, Peter ; Peringer, Petr (referee) ; Smrčka, Aleš (advisor)
The goal of this work is checking specific properties in trace which program should meet or which it shouldn't meet. Properties and their description are basis of this tool for post-mortem debbuging. Properties are transformed to deterministic finite automaton for checking in trace and their description is important for searching events in trace. Events are pass to automaton as input. Output of a tool is report if properties are meet or not. Solution provides check of properties regardless of log format and shows events that preceded violation of the properties.

Monitoring the influence of concrete composition on abrasion resistance
Černá, Hana ; Novosad, Petr (referee) ; Bodnárová, Lenka (advisor)
This diploma thesis focuses on the resistance of concrete to abrasion with regard to the raw materials used for their production. In the theoretical part of the thesis are described admixtures, different types of aggregate and aggregate composition which influence the resistance of concrete to abrasion. In the experimental part, 15 different C30 / 37, S4 concrete formulations were proposed. Different types of aggregates - fecal gravel (Žabčice), biotic granodiorite (Olbramovice) and amphibolite (Želešice) have always been used in the recipes. Fine ground limestone, micro-silica, high-temperature fly ash and finely ground slag were ingredients that were added to the proposed recipes. Consistency was determined by the method of cone seating and the density of fresh concrete. In the hardened state, concrete density, compressive strength, bending tensile strength, tensile strength, watertightness, concrete absorption, and abrasion resistance were determined using the Böhm method and wide wheel method. The test specimens were tested after 7, 28, and 90 days of maturation.

Study of the influence of additions on the durability of aerated concrete
Halešová, Adéla ; Voves, Jiří (referee) ; Hubáček, Adam (advisor)
The aim of this work is to summarise and consider the possibilities of using admixtures and their influence on the durability of aerated concrete.This bachelor's thesis is based on research findings concerning aerated concrete. Furthermore, it deals with the study of inert and active additions. The experimental part is focused on testing trial samples with the addition of admixtures. It examines what is the rate of the possible chosen physically-mechanical features such as the rate of air density, the durability of surface against the effect of water and chemical defrosting substances and achieving the required strength.

Casting of manganese steels and their use
Dufka, Martin ; Šenberger, Jaroslav (referee) ; Pernica, Vítězslav (advisor)
Austenitic manganese steel, often referred as Hadfield´s steel after its discoverer, has an irreplaceable place in foundry due to its specific properties. Due to local pressures and shocks, surface of castings is hardened, but the cast core retains its toughness. Thus, manganese steel is used for castings of highly stressed machine parts that are subject to abrasive wear. This bachelor thesis is concerned about methods of production, chemical composition, influence of some alloying elements on properties and structure of steel, heat treatment, material properties, reinforcement mechanisms and types of individual deformation reinforcements. Further attention is paid to the most frequent use of manganese castings in practice.

Requirements for manager of the construction company
Malková, Darina ; Louda, Pavel (referee) ; Linkeschová, Dana (advisor)
Bachelor’s thesis deals with the requirements for manager of the construction company. The theoretical part focused on manager attributes, knowledge, managerial activities and the ability to lead the team. The practical part bachelor’s thesis based on the hypotheses, which I checked by a questionnaire survey. This survey finds especially which requirements are placed on managers in the construction company and whether students of Faculty of Civil Engineering Brno University of Technology are comply with these requirements.

Numerical simulation of mechanical properties of cast irons
Haluza, Jakub ; Bouška, Ondřej (referee) ; Krutiš, Vladimír (advisor)
Diploma thesis in the first part deals with the production, properties and application of compacted graphite iron. After then calculation model which is used in ProCAST software for the predicting mechanical and structural properties of compacted graphite iron is presented and differences between versions 2010 and 2011 are shown. The last part of the thesis deals with simulation of mechanical and structural properties on the test specimen and real casting, which is poured in Heunisch foundry Ltd. and results of the simulation and measured values are compared.
