The main theme of this thesis is the usage of the test investigating the formation potential of trihalogenmethanes (THM FP) and its comparison with conventional indicators of water quality (CODMn, A254 and colours). As for the experimental part of the thesis, rating of the effectiveness of selected technological procedures has been applied (e.g.: coagulation, adsorption and ozonation in the act of treatment of artificially prepared water model with a higher content of humic substances in laboratory conditions). Based on the obtained results, it was found that the common indicators of water quality have very similar attributes and also complete each other. On the contrary, those attributes of indicators may not be sufficient in case of the evaluation of water quality with high content of humic substances. The findings made illustrate that the THM FP test enables the accurate evaluation of water quality, especially in connection with the content of an organic material susceptible to chemical changes. THM formation potential has proved its high value and also has confirmed that it can appropriately complete the other standarts that are being used for assessing the quality of treated water up to nowadays.

Master’s thesis handles about measurement on linear motors. Acts about set of two linear machines on one rail. One is motor and second is load. Thesis paies their mathematical description, control and measurement. It’s made measurement of the linear motor load characteristic. Next measurement have to do with losses in the converter. Is chosen measuring instrument t for measurement during working cycle. During working cycle has determine power eciency of entire drive.

The thesis deals with the problem of potential use of solar energy through the conversion into electric energy. The thesis analyses in great detail several types of conversion. My special concern included photovoltaic conversion and thermal conversion of solar energy using steam turbines for energy production. In the subsequent parts, I focus on the problem of photovoltaic, photovoltaic systems, and solar thermal power plants, their installation and use.

This Master’s thesis is focused on design of voltage converter’s system operating with supply voltage of batteries. There are selected appropriate types of batteries, converter topologies and modes of their control. The specified output branches are systematically divided into three separate modules. Each module is designed in detail with focus on high efficiency. The modules are implemented and optimized. Parameter of final modules were measured and compared with correctness of design and theoretical assumptions.

This master´s thesis is about searching for a connection between solar illumination and solar irradiance. The task is attempt to find out if it is possible to use one factor in order to determine the other one. Part of this thesis deals with cooling of virtual building.

Corrosion of steel reinforcement in concrete structures poses a risk reduction of durability and ability to perform the required function of structures for which they were designed.The objective of this work was to study the effectiveness of a new type of corrosion inhibitor with different concentrations of the active substance and its comparison with commercial products. The corrosion inhibitors were part of a comprehensive system repair materials from Betosan s.r.o. and using the electrical measurements was studied their effect in reducing corrosion activity caused by aggressive chloride environments.

Diploma thesis deals with the gas turbine closed cycle. The first part concerns the maximum of theoretical efficiency and practical excutable efficiency for the cycles without regeneration, cycles with regeneration and cycles with regeneration with split compression. The second part concerns the optimalization of the recuperator towards the speed of gas flow in the pipes of the recuperator. The third part includes weight and size design of two kinds of recuperators for different levels of regeneration.

This graduation thesis dwells on a worm gear design for an elevator mechanism in an already existing wheel case with actuator unit S3 for elevator type BOV 320/0,63. The work includes dimensional and control calculation for the worm gear and as an attachment you will find spiral worm and worm gear drawing documentation, including its specific location.

This diploma thesis deals with the problems associated with acquisition of experimental data from technological unit for biomass combustion with nominal capacity of 1 MW, with regard to determination of thermal efficiency. In the introduction part, parameters of currently available biomass-based fuels as well as of those with large potential in the future are summarized. Further, a review in the field of biomass combustion technology is given. Biomass boilers are compared according to their technical parameters, function and benefits and drawbacks. In theoretical part methods for determination of thermal efficiency by direct method, indirect method and modified indirect method are described. Main parameters influencing resultant values of efficiency are included into the analysis. In final part an evaluation of real operational data from prototype unit combusting wooden chips is made. Recommendations for further experimental data gathering and their processing with the aim to evaluate thermal efficiency are suggested.

My thesis is engaged in description of ineligibility original version of the elbow draft tube new constructed small hydro power plant Doudlevce. Other main purpose was construction of better hydraulic thus more efficient this draft tube. First chapter meets project small hydro power plant Doudlevce and it specifies this interesting contstruction of the power plant (for example position of the turbine in vacuum fontain) and many others information about it. Second chapter and its particular parts there deal with functions of this draft tube, for example out-flow of water from turbine and a principle of water-energy utilization placing behind turbine runner. There is also described energy profit and how to get it throught draft tube. There is an analysis of important quantities, which are used during the scoring of flow in the draft tube in third chapter. This part of my thesis is aimed to meeting their principles. There is one of the main purposes of this thesis, where is a description of ineligibility original version of the elbow draft tube in fourth chapter. It results sizable from Kaplan´s attemps and analysis of flowing based on computations in computer programme CFD Fluent. Fifth chapter is about general principles, which should be looked out during the construction of the draft tube. There is also project of new hydraulic better draft tube and its another parts. Last chapter compares original version with new better project based on computations in computer programme CFD Fluent. Comparison is made of specific criterion flowing of water, where are described quantites in third chapter, and efficiency of this draft tube.
