The aim of this work is to determine the influence of noise on determination of own frequen-cies for machine tool by operational modal analysis. For the assigned machine tool operation-al analysis is performed using Data-Driven and Covariance-Driven method for multiple exci-tation variants. Based on the results are created stabilization diagrams used to determine ma-chine tool own frequencies. The results for each excitation variant are compared to each oth-er and the effect of noise influence on the results is determined.

The topic of the diploma thesis is cost optimization in the company. The concept of optimization hides the effort to modify costs in order to achieve the best economic result of the company. In order to properly analyze and subsequently design the necessary measures, it is necessary to obtain a theoretical knowledge of the costs. The first part of the thesis contains theoretical knowledge. The second part deals with cost analysis and concrete areas that are most suitable for potential savings. The last part contains suggestions that should lead to savings.

This master’s thesis deals with creating a real-time simulation model of an aircraft piston engine with emphasis on heating and cooling of the engine cylinders. First part of this thesis focuses on characteristics of aircraft engines and differences with regular automotive engines. The next chapter describes the dependence of engine parameters on atmospheric conditions. The description of the real time model itself follows next. The results of the simulation model are presented and analysed at the end of this thesis.

A number of partial restructuring measures are offered to optimize business operation to improve its efficiency and performance. The structure inside the company is one of the most important tools for managing its performance and its correct definition, and a proper and meaningful distribution can play a key role in the competitive environment. In many cases, the requirement for optimization of operation will arise from the requirements of facility management, and therefore restructuring measures relating to organizational changes should be implemented with respect to the principles of facility management or should be based on its optimization. This thesis presents the impact of restructuring measures by centralizing of divisions on optimizing its operation with respect to the facility management. The aim of the dissertation is to evaluate the organizational change in the company with several divisions, taking into account the principles of facility management. The result of this thesis are the methodical recommendations during the establishment and evaluation of the division´s centralization in the company. It is based on the findings from the literature review and the real change in the building company.

This diploma thesis focuses on risk evaluation of water line for public use. The risk analysis is done in compliance with the methodology created by VODÁRENSKÁ AKCIOVÁ SPOLEČNOST, a. s. and by the method WaterRisk, created by Institute of Municipal Water management, Brno University of Technology, Faculty of Civil Engineering. The thesis clarifies the key points of the topic in question. Its readiness for passing in the Czech Republic and its core in relation to legislature. Then the thesis also includes a description of a specific water line. In the following two chapters the risks are studied according to the methodologies chosen.

The thesis deals with the possibilities of heat recovery in air ventilation systems. After a thorough analysis of the problems, the different ways of ventilation with the return of heat are compared even during simultaneous operation of the heating source. The research includes the selection of a suitable ventilation device with heat recovery based on a first investment and operating costs. Subsequently, the selected ventilation device is used for the HVAC project in the housing part of the multifunctional building. The project is created in BIM Revit software.

The Master's thesis deals with online vibration diagnostics of a milling center. It contains a methodology to determine the vibration operating limits and to detect machine of condition monitoring. The thesis also contains a general description of maintenance and technical diagnostics with a focus on vibrodiagnostics. The main part of the thesis is to solve the problem of determining the operating limits of spindle vibration depending on the production program. The essence of the solution is to determine vibration limits for individual milling tools.

This thesis deals with regenerative heat exchangers and their operational issues. The theoretical part explains rotary and fixed bed regenerators. Further it includes the most common issues we encounter in operation. Practical part presents a design of rotary regenerator which cools flue gas from wood chip boiler. Calculation contains stechiometry of flue gas and air, design of rotor, calculation of outlet temperatures, strength calculation, dynamic calculation and design of heat exchanger peripherals.

This Master thesis deals with the measurement and description of the synchronous generator , which is located in laboratories. First, the thesis deals with the theory of synchronous machines. This is followed by a detailed description of the involvement of laboratory genetatory unit. Subsequently, the work deals with the measurement of basic parameters of the synchronous machine and also quite thoroughly devoted to displaying transients at various levels on the digital oscilloscope. The dissertation aims to compare theoretical ideas with the measured results. Finally, it is shown what could be measured next to the generator set.

This master thesis determines and compares operating costs (energy balance) of family houses, depending on their age and during their life cycle. The basic terms, heat-technical properties and technological procedures of improving heat-technical properties are defined in the first part of the thesis. In the practical part, the operating costs of three older houses are determined. Variants of building modifications to improve heat-technical properties are suggested and evaluated. Certificates of energy performance were determined and the values compared, for both the current state of the houses and for the state after the improvement heat-technical properties. The thesis includes calculation of building modifications costs and the payback period of the investment.
