Energy-saving detached house
Ondruš, Marek ; Struhala, Karel (referee) ; Kolář, Radim (advisor)
The aim of the bachelor's thesis is to design a single-family house that is low-energy. The building is located in Hlučín, Opava district. The two-story detached L-shaped house features a flat sedum roof on the top and a flat roof that serves as a step-in terrace on the first floor. The main entrance is situated on the north-east side. The ground floor comprises a utility room, a small bathroom, a study room, a storage room under the staircase, and a social zone that includes the living room and a kitchen connected with the dining room. The first floor is the private zone that contains two children's rooms, a master bedroom, a main bathroom, and a walk-in wardrobe. The building's foundations are concrete strips, while the main load-bearing structures are masonry walls designed from sand-lime blocks with ETICS insulation and a reinforced concrete floor slab. The building's heating and cooling is powered by an air-water heat pump, which also heats the hot water. Comfortable indoor microclimate provides a heat recovery ventilation unit with supply ducts in ceiling voids and fans in rooms. Rainwater is collected in a stormwater accumulation tank and reused for toilet flushing and watering the garden. The photovoltaic panels on the main green roof generate energy that can be stored in batteries or used for household appliances. The building is connected to the combined sewer, water service pipe, and electricity service. External blinds and a pergola shading system help to reduce overheating during summer.

Securing IoT applications with Arm Cortex-M33 microcontrollers
Tonka, Marek ; Zeman, Václav (referee) ; Slavíček, Karel (advisor)
Bakalárska práca analyzuje vlastnosti moderných mikrokontrolérov s architektúrou ARM Cortex-M33 a ich prínos pre zabezpečenie IoT aplikácií. Teoretická časť je zameraná na predstavenie spoločnosti ARM spolu s charakteristikou architektúry ARMv8, na ktorej sú procesory Cortex-M33 postavené. Taktiež sa kladie dôraz na predstavanie novej technológie TrustZone, ktorá je klúčovým zabezpečovacím prvkom týchto procesorov. Následne je predstavený výber mikrokontrolérov a ich vlastností od piatich popredných polovodičových spoločností. Praktická časť zahŕňa inštaláciu a nastavenie dvoch IDE pre nasledovnú prácu s doskami NUCLEO-575-ZI-Q a LPC55S69-EVK. Na základe týchto vývojových dosiek sa testujú štyri jedinečné funkcie, ktoré poukazujú na výhody používania procesorov ARM na zabezpečenie aplikácií internetu vecí.

Possibilities of transmutation of spent nuclear fuel with advanced nuclear reactors
Ošust, Marek ; Brně, Dušan Král, Los Alamos NL a FEKT VUT v (referee) ; Katovský, Karel (advisor)
This bachelor thesis deals with the issue of transmutation of spent nuclear fuel. It describes the accelerator driven transmutator as well as its individual components. Examples of specific projects such as MYRRHA and CiADS are also given. The main objective of the thesis is the investigation of material properties of the spallation granular target. Compounds of heavy and light elements have been considered. Their physical properties, the number of neutrons generated by interaction with impinging proton beam and the resulting neutron energy spectrum were compared. The calculations were performed using the TALYS program.
