Data mining
Mrázek, Michal ; Sehnalová, Pavla (referee) ; Bednář, Josef (advisor)
The aim of this master’s thesis is analysis of the multidimensional data. Three dimensionality reduction algorithms are introduced. It is shown how to manipulate with text documents using basic methods of natural language processing. The goal of the practical part of the thesis is to process real-world data from the internet forum. Posted messages are transformed to the numerical representation, then to two-dimensional space and visualized. Later on, topics of the messages are discovered. In the last part, a few selected algorithms are compared.
Stress - strain analysis of inferios limb with fixator type Orthofix
Mrázek, Michal ; Fuis, Vladimír (referee) ; Florian, Zdeněk (advisor)
This diploma thesis aims to create a stress strain analysis of Orthofix external fixator applied to lower limb. The introduction summarizes the background research in available scientific publications, targetting the alternatives of treatment, namely application and fixation solutions of long bones. Furthermore parametric models of the fixator and tibia are created in CAD system CATIA. The fixator model enables to create different geometric variations simulating possible fixator settings and moment load in the range of 1-10 Nm. These geometric and loading states of fixator are solved via FEM in ANSYS. Single versions of the states of Orthofix fixator are then subjected to the stress strain analysis.
Factors affecting mortgage market
Mrázek, Michal ; Radová, Jarmila (advisor) ; Cibulka, Jakub (referee)
This bachelor thesis focuses on current issues regarding mortgage loans. The thesis aims to characterize the impacts of new regulations and selected macroeconomic factors on the mortgage market. The first part defines mortgage loans, including relevant terms connected to the field. Then, the impact of new legislature on banks and consumers in the mortgage business is researched. Furthermore, the thesis focuses on reccomendations of Czech national bank concerning indicators of LTV, DTI and DSTI. The second part characterizes selected macroeconomic factors and their impact on the mortgage market. The selected macroeconomic factors are gross domestic product, inflation, unemployment and interest rates of mortgage loans. Firstly, the impact of these factors is researched on quantity and sum of new mortgage loans. Then, the macroeconomic indicators are quantified and analyzed using regression analysis.
Waste management in selected city
MRÁZEK, Michal
The thesis is focused on the waste management in the town of Tábor. The main aim is to determine the inhabitant's satisfaction with collecting waste, identify main problems and give suggestions to improve the current situation. The theoretical part focuses on legislation and basic concepts of waste management. The practical part analyses the quantities of each type of waste, that were produced in Tábor in 2015. There are determined costs and revenues associated with waste management too. At the end of the thesis is made a research about inhabitant's satisfaction with waste management in the town of Tábor. There are given some suggestions, which help to improve current situation there.
Explanation of the sloshing motion in a tank, for a moving tank, for a fixed tank
Mrázek, Michal ; Habán, Vladimír (referee) ; Fialová, Simona (advisor)
This bachelor's thesis deals with mathematical model of sloshing in a tank. Laplace's equation is developed. Boundary conditions for a still rectangular container and for a container under sinusoidal translation are established. Expressions for the free surface elevation and natural frequencies in oscillating tank are determined. Baffles are suggested as a method to minimize the free surface elevation. In the final part, analytical model is compared with numerical solution with overall good agreement.
BIOMECHANICAL STUDY OF EXTERNAL FIXATORS APPLIED TO TIBIA
Mrázek, Michal ; Horyl, Petr (referee) ; Janíček, Přemysl (referee) ; Florian, Zdeněk (advisor)
External fixators are used in a treatment of complicated fractures and their properties have a crucial impact on treatment quality. Therefore, this thesis is concerned with a biomechanical study of a bone (tibia) with applied external fixators via strain-stress analysis and their comparison with a state of tibia without applied fixator (physiological state). After creating the volume models of geometry of tibia and seven variants of external axial fixators, the corresponding finite element method (FEM) models are created. The analysis of tibia without applied fixator and tibia with all studied fixators is made for three states of load which correspond to characteristic load states during the first stage of treatment. The strain-stress analysis is made using finite element method. Furthermore, the methods of displacement and rotation evaluation during loading are proposed. One can conclude from the results of the strain-stress analysis how the different variants of fixators prevent the displacement and rotation of the bone during the different load states and the comparisons with the physiological state of bone are made. Bone tissue loading is determined from the distribution and the values of the first and the third principal stresses. Finally, comparing the results of all variants the influence of the fixator length, the gap between the fixation elements near the fracture, the number and the setting of the fixation elements on the fixation properties is analysed.
Strain stress analysis of proximal tibia end with replacement
Tekalová, Soňa ; Mrázek, Michal (referee) ; Florian, Zdeněk (advisor)
This thesis deals with stress analysis strain proximal end of tibia with total joint replacements. The analysis is done on the basis of deformation characteristics of voltage, through the finite element method (FEM). We have developed two-dimensional models of the proximal end of tibia with tibial components total endoprosthesis (TEP), without loss and bone loss. Geometry model is created based on data obtained from computerized tomography, which were further processed in the program, Rhinoceros 3.0 and SolidWorks 2009th Computational solution was carried out by finite element method in Ansys Workbench 12.0. The model without loss of bone tissue was tested the hypothesis that the deformation is very small and there is no violation of the shank prosthesis. Due to loss of bone tissue is lost support to the tibial pulse in the proximal tibia and by a progressive increase in stress, which can lead to a breach of the shank total joint replacement. The analysis results show that, if the loss of bone tissue, so that the tibial part of the TEP will lose support, there is a crack stem total hip replacement due to stress.
Adaptive optimal controllers with principles of artificial intelligence
Mrázek, Michal ; Malounek, Petr (referee) ; Pivoňka, Petr (advisor)
Master’s thesis describes adaptive optimal controller design which change parameters of algorithm based on the system information regard for optimal criterion. Generally, the optimal controller solves the problem of minimum states vector. Problems of desired value and steady-state error are solved by variation in optimization algorithm.
Assessment of Economical and Social Benefits of Selected Collection Yard
MRÁZEK, Michal
The bachelor thesis is focused on the assessment of economical and social benefits of the collection yard in Klokoty, which is situated in the town of Tábor. The main aim was to identify the costs of all activities in this collection yard during the period of one year. Next aim was to analyze the quantities of each type of waste, that people give back to the collection yard. The there were described ways of waste disposal. Another aim was to determine profits from the sale of waste. Last aim was to evaluate overal situation of collection yard and give some suggestions.
