This diploma thesis aims to design a methodology for technical audit of water tanks. The first part presents basic information on water tanks, followed by a brief summary of Czech legislation related to developing water tank renewal financing plans. The key part of the thesis is designing the structure of TEAA water tanks module, which will be included in TEA Water methodology, being developed at Institute of Municipal Water Management. The module under proposal is implemented as a MS Excel application, which is used to assess selected water tanks. The assessment results are compared to results obtained using TEA Water web application, which implements a draft of the TEAA module from October 2014, and to the results obtained using TAWAT.xls application.

This diploma thesis is about using heat pump (HP) to gain energy. The theoretical part contains introduction, historical development of HP, principle of function, description of individual components, working cycle of heat pump and sources of lowpotencial energy and accordingly possible types of heat pumps. The practical part is devoted to proposal of appropriate type of heat pump for heating and warming of tap water for family house and economical evaluation of this solution.

The main goal of this diploma thesis is the examination of the influence of structure directionality on fatigue properties of formed aluminium alloy 6082/T6. The main attention is focused on the study of the influence of structure directionality on kinetics of short fatigue cracks growth. The measurement of short fatigue cracks growth was performed on cylindrical samples. The samples were made in two different directions; one parallel with the forming direction and second perpendicular to the forming direction. Servo hydraulic machine MTS 880 was used for the cyclic loading. The samples were cycled at two different constant stress amplitudes. Cyclic loading was systematically interrupted in order to measure the length of short cracks by a light microscope. Tensile tests, measuring of cycling hardening-softening curves, observation of microstructure, observation of surface relief, measuring of microhardness and fractographical analysis of fracture surfaces were used for further examination of the influence of the structure directionality. Some of these measured characteristics did not show any influence of the structure directionality (microhardness, fatigue life curve, Young modulus). In other cases is this influence measurable, however insignificant (yield stress, ultimate stress, cyclic hardening-softening curves and kinetics of short fatigue cracks growth). It can be summarised that the material, though the directionality of its microstructure is apparent, shows relatively isotropic mechanical behaviour.

Diploma work includes summary of aeroplanes accidents, incurred by human factor malfunction in general aviation and in ultralight aeroplanes category on Czech Republic territory since year 2000. It analyses accidents enclosures with a view to discover similarities near particular accidents. From ascertained lockworks ared proposal created for possibly steps, how prevent rise of these accidents. Part of this work are also attachments (formularies, etc.).

The purpose of this dilploma thesis is to evaluate mechanical and structural properties of two types casts of Al-alloy (components of the engine block) which were made by different technologies. Die casting with local squeeze casting and without local squeeze casting. First of them is used in lot manufacture of the current engine block. The aim of the foundry is to change the technology and start to produce new block by the die casting without local squeeze casting. The samples were taken from the both parts (lower and upper part) of the current and the new engine block which are made in foundry of Skoda Auto a.c. in Mladá Boleslav. Sets of mechanical and structural properties were selected, evaluated and tested by statistical programs. It was used fifty casts of the engine blocks for the experiment.

DLUHOS, J. Effect of the human factor on small aircraft accident. Brno: Brno University of Technology, Faculty of Mechanical Engineering, 2013. 90 s. Supervisor Ing. Jiří Chlebek, Ph.D. The Master’s thesis focuses on the safety of civil aviation, which is in 80% of the accidents caused by Human Factor, Human Error or just Pilot Error. The main goal of this Master’s thesis is evaluation and assessment of the causes of aircraft accidents of general civil aviations operations of the Czech Republic. In the practical part of the Master’s thesis were analyzed accidents of aircrafts in the category with maximum take of mass to 2250 kg and ultra light aircrafts incurred in the Czech Republic from 2006 to 2012. In the conclusion were analyzed main causes of the aircraft accidents and were proposed further measures to reduced accidents caused by Human Factor.

In my Master´s thesis I am concerned with the questions of the human factor in air traffic control. The work is mainly focused on the air traffic controller and discusses the influences that directly or indirectly affect the air traffic controller. Considerable attention is paid to the errors that may occur during the management, their analysis and proposals for their elimination, respectively their complete disposal. The main idea is to understand the thinking of the air traffic controller as the human element in an organization and applying theories to reduce the errors in the air traffic control.

This diploma thesis is focused on development of a fast method for site-directed gene mutagenesis in Streptococcus zooepidemicus based on the mechanism of natural competence. Several genes were selected based on experimental data which highly probably influence hyaluronic acid synthesis. The deletion of the selected genes from genomic DNA was performed as proof of concept, and the resulting recombinant strains were characterized regarding changes of hyaluronic acid precursor concentrations (glucuronic acid and N-acetylglucosamin) in time of cultivation and the end production of hyaluronic acid.

The task of this thesis is to introduce the problems of vibrafon sources in asynchronous motor and their effects and risks to the engine. We will classify the sources of vibration, we will focus for the defects of bearings and for dynamic and static eccentricity. The thesis includes vibration measurement for asynchronous motor, analysis and evaluation of bearings defects and eccentricities.

Diplomová práce popisuje metodiku výpočtů částí náchylných k rozvoji mnoho-ohniskového únavového poškození (WFD). Nejdříve se práce zabývá rozborem předpisů letové způsobilosti souvisejících s WFD pro letadla certifikovaných podle FAR 23 v kategorii commuter. Následuje popis metodiky únavového výpočtu a predikce šíření trhliny. Dále jsou popsány řešení pro výpočet faktoru intenzity napětí pro základné konfigurace trhliny, tam kde to bylo možné v uzavřeném tvaru, jinak ve formě tabulky. Hlavní částí práce je návrh algoritmu AIMA schopného provést kompletní analýzu části náchylné k rozvoji únavového poškození na více místech (MSD). Model se validoval únavovou zkouškou vzorku přeplátovaného spoje dolního panelu křídla. Následně byla analyzována reálná konstrukce spoje dolních panelů křídla letounu L 410 NG.
