The diploma thesis deals with the design of a low energy house in two structural variants, namely wooden frame construction and massive brick construction. The object is designed on a specific plot with two above-ground floors. The house meets the requirements of a three-member family. Both objects will be compared in terms of energy intensity and energy prices. The thesis is divided into two parts. In the first part of the thesis there is a description of how the basic wooden constructions are divided. There are also basic characteristics of some wooden frame structures and solid brick structures made of lime sand bricks, including their positive and negative properties. Basic energy balance and categorization of buildings in terms of energy intensity follows, including descriptions of the individual categories. The second part of the thesis deals with the design of the wooden structure itself. The text part contains the accompanying and the summarizing technical reports to the designed object. The perimeter structures of the wooden structure and the perimeter structures of the massive brick structure in contact with the exterior are assessed in terms of thermal technical requirements for the perimeter shells. At the end of the work the timber and brick structure are compared in terms of heat losses and energy demands. In addition, the individual alternatives for heating and water heating are compared in terms of fuel consumption costs and price comparability of 1 m2 of perimeter structures of brickwork and wooden structures. The drawing part contains a study of frame wood and brick structures. The building permit documentation is prepared for the wooden building. Part of the project documentation is calculation of heat losses, energy performance certificate, calculation of the energy intensity of the building, energy label of the building envelope and 3D visualization of the proposed building.

The issue of descaling is an important part of the forging and heat treatment of steel and semi products of steel production. Rising of new information and study of this process can increase efficiency and improve the surface quality after descaling. This thesis is focused on the mechanisms of the high pressure hydraulic descaling qualification and study of the chemical compounds of which the scales grown. To achieve all goals of this work and to get a comprehensive view of descaling process, few experimental measurements and numerical analyses were performed. All experimental measurements were focused on obtaining data about fundamental parameters and effects of the hydraulic descaling. The data obtained from measurements were applied to numerical analyses, which aimed to discover a deeper relation and to confirm the experimental results. This thesis can be divided into two main parts. The first part is devoted to parameters of the water jet study. The main studied characteristics of the high pressure hydraulic water jet were heat transfer coefficient and impact pressure at different modes such as standard or pulsating water jet. Experimentally measured data of these parameters were applied in numerical analyses. The numerical analyses were focused on studying the impact of the water jet parameters on the stresses in the oxide scale layers. A further water jet analysis was focused on the influence of the individual parts of the hydraulic system (such as water chamber or stabilizer) on its characteristics. In this part different types of the water chambers in combination with different types of stabilizers on the impact pressure values were investigated. These measurements were supported by fluid flow analysis through the hydraulic system. The second part of this work was focused on getting mechanical properties of the oxide scales from specimens prepared from standard structural steel and specimens from silicon steel. In this thesis, the influence of various parameters and characteristics was studied on these two types of steel. Mechanical properties of oxide scale structures were carried out by the Small Punch Test method. To obtain the fundamental mechanical properties such as Young´s modulus, yield strength and ultimate strength, material parameters based on the measured data were optimized. The whole work was carried out in order to get valuable and comprehensive results about high pressure hydraulic descaling process and influencing factors as well as about oxide scales themselves.

The thesis is divided into theoretical and practical part. The theoretical part includes issues associated with runoff and discharge, methods for discharge measurement and measurements of uncertainties. The practical part of the thesis describes a specific process flow measurement in Kopaninský and Jenínský stream. There is a familiarization with the water flow velocity measurement and comparison methods of volume measurement discharge with continuous measurement. The results of the practical part served to refine the rainfall-runoff processes in research catchment areas. Refined values of the flow rate were used as input data for the calculation of the runoff coefficient and for quantifying the losses of nutrients from the catchment areas. Calculation of the runoff coefficient and nutrient losses were compared for the original and the revised equation discharge curve. Volume measurement discharge has shown that the different conditions above measurement weir during continuous monitoring lead to the uncertainties of measurement. That´s why one has to approach to each flowmeasurement individually and consider the situation in a particular installation.

The adhesion in the wheel-rail contact can be effectively controlled by using the friction modifier. Adhesion control can reduce excessive wear of the contact bodies or noise. The essence of this diploma thesis is to determine the optimal amount of friction modifier in wheel-rail contact depending on the climatic and operating conditions. For experimental study of the behavior of the friction modifier, the twin-disc device is used. Twin-disc simulates and controls the most important operating parameters such as speed, slip, attack angle or contact pressure. On the basis of these findings, the off-board top-of-rail lubricator system was designed. This system controls the amount of friction modifier according to current climatic and operating conditions.
