Construction is a very dynamically developing industry that is placing ever greater demands on the properties of used building materials and structures built on them. In this context, there is a long-term trend to use construction materials made from natural quickly renewable raw materials. These tendencies are caused by natural reaction to the overly technological modern society, as well as efforts towards a greener approach in construction. In this sense, the natural materials from renewable sources means technologically processed organic material of plant origin. Dissertation focuses on the research and subsequent development of filling materials for vertical and horizontal structures based on quickly renewable materials. Pivotal quickly renewable raw material used in the production of filling material is technical hemp. Technical hemp is quickly renewable raw material with very good properties very similar to wood. Furthermore, the research focused on secondary raw materials, which partly replace the binder of the filling material. The resulting filling material has good physical-mechanical and thermo-technical characteristics.

Presented master's thesis is focused on studying electroinsulating epoxy resin-based sealings. It describes the chemical composition, production, properties and measuring methods of basic electric quantities of these materials. The aim of the thesis is to compare several sets of samples of composite epoxy resins with different kinds of micro-ground siliceous sand as a filling. The temperature and frequency dependence of relative permittivity, dissipation factor and inner resistivity are measured for given samples.

This diploma thesis deals with the fundamental properties of epoxide mixtures, as determining of these fundamental properties of epoxide mixtures could in the case of favorable results lead to diminishing the amount of defects in epoxide-embedded instrument transformers. As the influence of effects in the manufacturing process of transformers causing poor quality is very extensit, the biggest emphasis is laid capitally on the influence of the epoxide casting mixture composition. The thesis describes the manufacture technology including used methodics and materials. The compositions of epoxide resins and the mechanisms of their curing. Also, the definitions of fundamental properties of dielectric materials and the description of diagnostic methods used to relative permitivity, dissipation factor and inner resistivity are included. suitable casts of acquired samples were set and dried out within the experimental part, followed by measurement of fundamental electrical properties in temperature and frequency relations. Hereafter a comparison of individual samples and the evaluation of their electrical properties will be carried out.

The lead-acid batteries used in hybrid electronic vehicles HEV operate in high-rate mode in a state of partial charge PSoC. It occurs when the degradation mechanisms related to irreversible sulphation and negative electrodes are a limiting factor in the life of lead-acid batteries. The electrode system was applied to experimental pressure cells of different sizes. Exp. cells were subjected to measurement and evaluation of potential negative electrode, a negative active mass resistance, contact resistance of transition collector - the active mass with the evaluation and measurement of pressure fluctuations within four PSoC runs.

The main goal of this thesis is to create business plan for the establishment of the petrol station operating as BENZINA franchise. Entrepreneurship, requirements of the business plan, franchising and definition of used analysis are described in the theoretical part. Necessary analyses are performed in the analytical part. Suggested business plan and schedule of its implementation are described in the last part of this thesis.

Aim of the Master’s thesis is analysis of problems of the dangerous goods road transportation, especially transport of flammable liquids. It analyses the European Agreement concerning the International Carriage of Dangerous Goods by Road and its special requirements. Thesis also covers road tanker accidents and the removal of leaked petroleum products. In practical portion the work on resistance testing of asphalt mixtures against several types of fuel is presented.

As part of my master's thesis I have conducted a visual inspection and record failures of bridge roadway at selected highway bridges, roads D47, D3 and D8 and photographic documentation, which is included in Annex. Also I have based on their speeches and documents the results of control tests determine their causes and to propose appropriate repair or maintenance.

The thesis is focused on determining the energy flows and the creation of an internal microclimate swimming pool halls. It describes the problems of design, the potential risks associated with the use of pools and thermodynamic processes heat and mass transfer. For this purpose was developed simulation program, which examines the behavior of heat and humidity in the room depending on external factors. The room can be simulated for any time period and geographic location. The outputs of the simulation are heat and mass balance, which will be covered air condition units. Three variants were designed and optimized solutions comparing claims on their operations. The experimental part is focused on the evaporation of the water. Measurement examines dependence of the speed of evaporation of water at different boundary conditions. Was investigated temperature dependence of water, temperature and relative humidity and air velocity above the water surface.

This dissertation deals with impedance measurements of lead-acid accumulator. Main aim was to study recent problems of impedance measurements of lead-acid accumulator and most importantly to extend difference method and also to interpret its results. The original DC difference method was developed earlier at our Power Sources Laboratory of Department of Electrical and Electronic Technology. The DC difference method and also the new AC difference method are both non-destructive, which means that experimental data can be obtained in situ. New method provides more accurate set of information because of its wide frequency range nature. Electrodes of lead-acid accumulator were analysed with special attention to collector / active mass double layer and to active mass itself. Various states and operation regimes were investigated. Obtained data contributed to better understanding of involved degradation mechanisms. Main aim of other experiment was to observe and interpret corrosion rates of electrode collector composed of various lead alloys. Last but not least charge and discharge regimes e.g. 100% deep of discharge regime, partial state of charge (PSoC) regime and pulse charge regime were analysed. BioLogic VSP was the device used for almost all experimental measurements. It takes a lot of effort to optimise VSP operation regime. Best operation regime of VSP for the difference method was suggested too.

This thesis is completion of whole stage of researches and it is a result of existing need of increase efficiency, utilization rate and service life of lead acid batteries VRLA planned for utilization in hybrid electric vehicles in mode of partial state-of-charge PSoC. During the application of mode PSoC at lead acid battery occurs irreversible sulfation of negative electrodes and thus to loss their charging capability. This phenomenon, according to the latest trend called PCL3, isn´t connected with subsequently referred effects PCL1, PCL2, show up on positive electrodes. Result of this thesis is finding a new types of additives, determine their optimum amount and size in such a way that innovated composition of negative active materials be able to resist sulfation of negative electrode during operation in mode PSoC. Part of the effort to clarify actions ongoing on negative active material and causes non-returnable sulfation electrodes is also monitoring of structural changes electrode active material by using environmental scanning electron microscope, which helped to clarify processes related with loss of capacity in mode PSoC. Special attention during reserches was focused on study of the properties contact layers between collector and electrodes active material and itself active materials lead-acid battery druring exploitation. There were gain new information about influence repeated cycling of (charging, discharging) the critical area of the electrodes. Measurements was carried out on specially prepared experimental electrodes DC Difference Method, this enabled obtain data in situ.
