The master thesis deals with design of the fully differential frequency filters working in the current mode and is focused on possibilities of the natural frequency and the quality factor adjustment. At the beginning, there is a brief description of frequency filters and active elements (MO-CF, FD-CF and DACA), which are used in the thesis. Furthermore, simplified signal flow graphs design method and transformation of passive and active elements to the differential structures are described. The designs of four differential circuitries which provide possibility of tuning the natural frequency or quality factor by the gain of the DACA element are shown in the thesis. Simulation results made in OrCAD program with help of third-order models are included. The practical implementation of the differential frequency filter for tuning of the natural frequency by the DACA elements is shown in the last chapter.

Master's thesis deals with design and static solution of foundation slab of mountain hotel. Two calculation versions are made – simplified („inverse ceiling“) and calculation using software RF-SOILIN. This thesis also includes a comparison of both results. Reinforcement is designed for more accurate internal forces and the assessment of structure is performed according to the 1st limit state of capacity.

The aim of this theis was to design of load-carrying steel structure of shopping mall in two variations. Geometric proposal and examination of structural element was made for both of variations. Then one variant was selected for detailed elaboration of details and drawings.

The main subject of this study is the improvement of predicative ability of previously developed mathematical model for prediction of so-called “fouling critical velocity”. Attention is devoted especially to the flue gas side fouling process on active heat transfer surfaces in tubular heat exchange tube banks installed in waste incineration process plants and also a technical – economic analysis based on obtained results. The model improvement consists among others in taking into account another forces (electrostatic, capillary etc.) haven't yet been considered, which influence the mutual contact between flue gas particles in case of sedimentation fouling or the contact between particles and heat exchanger tube walls respectively. The improved model has therefore more predicative ability to the reality of fouling process. The results are used for technical – economic analysis, which determines an optimal heat exchanger design with respect to fouling. Furthermore, the algorithm of this analysis, essential fouling mechanisms, fouled heat exchanger surface cleaning methods as well as fundamental knowledge of fouling coefficient prediction are presented, whereas the emphasis is placed on industrial tubular heat exchange equipment installed in waste incineration process plants.

This master thesis concerns about problematics of wind turbines. The document summarizes basic theory based on the law of momentum conservation which is essential tool for the design and calculation of wind turbines. The theory is complemented by number of correction factors and then used in the design of wind turbine for specific parameters. The calculation is performed iteratively using Matlab software and the actual code is given in appendix. Graphs summarizing the progress of various units along the blades are presented in the document. The final section briefly describes advanced topics of aerodynamics concerning other important factors that the field of wind energy deal with in recent time.

Diploma thesis deals with creating of computational model of welded frame to perform strain-stress analysis. Thesis aims at verification of welded joints and their possible changes. The next goal is to compare stresses obtained from calculation with respect to welding standard and FEM analysis.

The aim of this master’s thesis is a design of the footbridge that transfers separately pedestrian and bicycle traffic over the expressway and the local creek. Chosen footbridge, which were one of two possible designs, consists of a monolithic bridge deck suspended on the V-shaped pylon. Thesis contains a static calculation of the structure modeled in ANSYS software. Design and assessment are according to the current European standards

This thesis deals with the nonlinear analysis of stability loss of flue gas pipe. This pipe is a part of desulphurization line. The thesis describes the creating of a simplified FEM model. It also describes the setting of the boundary conditions of the model for few loading cases. These cases differ by preference for one of the load as dominant. There are proposed several variants of stiffening by light ring stiffener. The work is finished by comparing the resistance to the stability loss of the reinforced variants and unreinforced model of flue gas pipe.

Topic of the master’s thesis is design and assessment of steel construction of the industrial building used to glass sand treatment. The building has the top view dimensions 12,0 x 12,0 m and roof ridge height 15,6 m. Disposition if the individual elements was designed according to conditions of the technology and production process. The thesis focus on creating of computational model and assessment to ultimate and serviceability limit states of individual elements. Further thesis contains of design and optimisation of some joints.

This diploma thesis deals with the comparison of the results of simulations of the numerical model WRF in the prediction mode for 9 schemes of boundary layer parameterization and in the climatic mode for 4 selected schemes. The first part of the work is devoted to the WRF model and especially its options for model physics with a focus on boundary layer schemes. The second part describes the experimental setup of the performed simulations. The third part then compares the obtained results for the prediction and climate mode with the measured data.
