This bachelor thesis aims to design a single-family home. The residence is designed from energy-efficient sand-lime bricks with an External Thermal Insulation Composite System (ETICS) that ensures efficient insulation, embodying passive construction techniques for all-year thermal comfort. The ground floor contains a master bedroom, a bathroom, a kitchen, a utility room, and an entryway, all connected through a central hall that serves as a functional circulation. We can find an another bathroom on the first floor, two children's bedrooms, and another master bedroom with walk in closet. Foundations comprise plain concrete strips. The house will be connected to the freshwater service pipe and sewer service pipe. Fresh water will be heated by a hot water cylinder. From the hard landscaping by drainage paving and from the roofs by storing in the storage reservoir for watering the garden, excess rainwater will be infiltrated by infiltration soakaway crates. Heating in the house will be provided by a pellet boiler in the season of winter, and by solar thermal collectors, in a the summer time. On the ground floor by floor heating and on the first floor by ceiling heating system. All will be supported by photovoltaic panels with batteries in the utility room. Mechanical ventilation with heat recovery will be placed on the wall in the utility room and will supply fresh and extracted exhaust air.

Technology for removal of micropollutants from water
Voldán, Jakub ; Biela, Renata (referee) ; Kučera, Tomáš (advisor)
The issue of contamination of water sources by emerging micropollutants is an ongoing challenge for the water industry. This thesis is focused on the most common micropollutants such as pesticides, pharmaceuticals and endocrine disruptors (per- and polyfluoroalkyl substances, bisphenol A or phthalates). In addition, attention is given to water treatment technologies for the removal of these micropollutants from water treated for drinking purposes. These include adsorption on activated carbon, advanced oxidation processes and membrane processes. The practical part deals with the site Chroustov u Bohdalova, where above-limit concentrations of the pesticide acetochlor ESA have been observed. Subsequently, a design of a technological stage for the removal of the mentioned pollution is made for this site as a supplement to the existing water treatment technology at the Chroustov water reservoir.

Exhaust Temperature Stabilitation Systems for Turbocharged Engines
Böhm, Michael ; Charvát, Pavel (referee) ; Vondrák, Adam (referee) ; Štětina, Josef (advisor)
This paper describes the possibilities of reducing temperature pulsations in the exhaust manifold of an internal combustion engine. For this purpose, the concept of a heat reservoir with a phase change material that can store the heat generated in the exhaust manifold is chosen. At a temperature lower than the phase change temperature of this material, the heat storage is then able to transfer the heat back to the exhaust gas, thereby reducing the temperature pulsations. The actual design consists of an advanced heat storage design consisting of an assembly of smaller tubes that increase the heat output of the storage while causing minimal pressure drop in the exhaust manifold. This concept is validated and compared with a series engine without a stack through simulations in both 1D and 3D computing environments. The designed and constructed prototype stack is subjected to experimental testing to confirm its performance. The effects of the electrically assisted turbocharger on the exhaust gas temperature are also analyzed. Finally, all the results are summarized showing the overall potential of this system and a possible way forward in the development of these stacks with phase change materials is outlined.

Electron microscopy and spectroscopy of nanophotonic structures and materials
Řepa, Rostislav ; Paták, Aleš (referee) ; Křápek, Vlastimil (advisor)
Bleskosvodný jev je dobře známý princip elektrostatiky, který vyjadřuje vznik silného elektrického pole v blízkosti zakřivených částí nabitého vodiče. V oblasti plazmoniky je podobně pozorován vliv lokálního zakřivení na indukované elektrické pole v okolí kovových nanočástic (plazmonických antén). Kromě tohoto tzv. plazmonického bleskosvodného jevu přispívají k zesílení pole i další jevy, jako je rezervoár náboje plazmonické antény, lokalizace povrchové plazmonové vlny, nebo interakce mezi dvěma plazmonickými anténami. Tato práce využívá spektroskopii energiových ztrát elektronů a elektromagnetických simulací ke kvantitativnímu zkoumání těchto odlišných jevů tím, že izoluje jejich dílčí příspěvky k velikosti indukovaného elektrického pole v okolí plazmonické antény.

Volumetric and Evaporation Analysis of the Landštejn reservoir
Hánová, Karolína ; Bednář, Martin (referee) ; Marton, Daniel (advisor)
This bachelor thesis focuses on the volumetric analysis and estimation of evaporation from the water surface of Landštejn reservoir. The main objective is to determine new bathymetric curves of the reservoir based on the most recent bathymetric survey of the bottom and then to estimate the amount of evaporated water for a selected period. To achieve these objectives, ArcGIS tools will be used to create a digital terrain model that will allow accurate calculation of the bathymetric curves through volumetric analysis. The amount of evaporation will be determined using selected empirical formulas and simple balance analysis, taking into account the standard ČSN 75 2405 concerning the water management design of reservoirs and comparison with data from the Czech Hydrometeorological Institute. The practical part of the work includes the creation and evaluation of a digital terrain model of the Landštejn reservoir and subsequent estimation of evaporation based on average temperatures and other meteorological data. The results show new bathygraphic curves and provide accurate estimates of the volume of water evaporated from the reservoir over the specified period. This work contributes to a better understanding of the hydrological processes in the Landstejn reservoir area and provides important input for more effective water management planning and management.
