The submitted work deals with the design of the working chamber of the electron beam welders. This vacuum chamber of the cubic shape, with a volume of approx. 100 litres will be used in the ÚPT of the AV ČR v.v.i. during building an experimental welding with electron gun performance 2 kW with accelerating voltage 60 kV. The theoretical part is about the theory of electron welding, electron beam welders of basic sections of the facility, and about possibilities of the technology for welding working chambers. In the practical part of the thesis is being thought out the design of the working chamber (construction chamber in design software), the strength test of construction chamber in the software ANSYS and the design of appropriate methods of welding. The sample of the material which is the stainless steel 17240, from which the chamber will be made, have been used in methods of welding TIG and MAG that was verified by the suitability of the chosen methods of welding.

This master’s thesis describes the design and calculation of the biomass hot water boiler which should be used for heating of office buildings in a collective farm. Fuel composition was determined by recommended literature. Stoichiometric calculations were processed for the fuel composition. The required boiler heat output was determined and compared with the original gas boiler, which was previously used for heating. The thermal calculation of the boiler and the design of the heat exchanger was also performed.

The carbonation of the building materials based on the ordinary Portland cement is relatively well-known and extensively studied phenomenon. Conversely mechanism, reaction products and factors affecting the carbonation of the alkali activated materials are still not sufficiently clarified. In this work, the progression of the carbonation of the alkali activated materials under different conditions was investigated. The reaction products and the microstructural changes were determined by XRD respectively SEM-EDX analysis. The corrosive conditions due to the decreasing of the pH of the binders by the carbonation were observed by XPS analysis of the steel fibers. The carbonation of the alkali activated samples was compared with the reference samples based on the Portland composite cement. Besides these analyzes, the mechanical properties of the binders were monitored.

The aim of this thesis is modelling of chamber for plant cultivation under defined conditions. First part of the thesis contains theoretical introduction to thermodynamics and humid air problematics. In the next part of thesis, the growth chamber model was designed. Model parameters were obtained during fytotron identification. Chamber control algorithm was designed using the model. The control algorithm was programmed into chamber control unit and its functionality was practically tested.

The aim of this thesis is to make more detailed disposition solution of the variant C.2 of shipping channel Přelouč II from the possible variants provided by ŘVC CR. The solution contains detailed technical documentation of the lock chamber. The study is divided into several parts, including an engineering report, hydrotechnical calculations, project documentation of the shipping channel and lock chamber and the photographic docu-mentation of the locality.

The thesis is concerned with the use of 3D mathematical modelling for flow simulation and separation efficiency in a single side weir CSO chambers. Analysis of the effect of turbulence model and computational grid on simulation results has been carried out in order to maximize the efficiency of numerical simulations. The goal of the thesis is to examine the effect of scum board position on separation efficiency of a single side weir CSO chamber.

The thesis aims to explore the relationship of international professional organization ACCA, respectively ICAEW and Faculty of Finance and Accounting (VŠE), and the knowledge to confront each other. The introduction emphasized the importance of professional organizations in connection with the voluntary and compulsory established organizations. The main part of this thesis is focused on the organization ACCA, which deals with her qualifications. The final part closer describes the cooperation between ACCA and FFA in connection with obtaining the accreditation. This part is complemented by the procedure to obtain the accreditation.

This thesis is focused on a detailed analysis of the mechanisms of electromagnetic wave propagation in anechoic chambers. The analysis takes into account the influence of the measurement distance, setup of anechoic chamber and other parameters. Furthermore, the work deals with a validation of both types of anechoic chambers and examines the impact of selected parameters on the measurement results. Based on the theoretical analysis and practical measurement, the comparation between semi and fully anechoic chamber, or a three and ten meter measuring distance was made. This thesis also contains a detailed analysis of sources of the uncertainty.

In thesis is dealt with problematic of how the value of air permeability may be affected by properties for water vapour diffusion with regard to OSB material There were chosen two main brands of OSB at Czech trade market Two specimens of OSB with different thickness were chosen for each brand. As a first the specimens were tested for air tightness to work out a value of air permeability for each specimen. Afterwords, the testing was conducted for gaining properties of water vapour diffusion on each specimen. As a final assessment was analysed the impact of properties of water vapour diffusion on the air tightness for each specimen. The general meaning of gaining higher air tightness with higher water vapour resistance was proved . It was shown that with raising thickness is usually gotten higher value of water vapour diffusion resistance. However it could not mean getting high air tightness. The crucial parameter is the quality of the material for gaining higher resistance against water vapour diffusion as well as for higher airtightness.

The aim of the diploma thesis is to design a drying chamber for meat/salami processing. The design itself comes after the necessary information regarding meat drying and curing has been given. The chamber comprises a main frame, stainless steel chamber, chain conveyor, powertrain and a ductwork for the air treatment. All the parameters of moist air are given as calculated for the states encountered during the drying process, i.e. air dehumidification, when passing the cooling coil, and heating. The control system to meet the required environment condition is also suggested.
