The influence of electrolyte additives to lead-acid batteries properties
Dohnal, Martin ; Zimáková, Jana (referee) ; Bača, Petr (advisor)
This day is a lead battery is most prevalent in the automotive industry. Which is a source of energy when starting the car. In recent times the battery is used not only for startups, but also when driving in city traffic. This behavior can know the concept of a hybrid car. Which is used an electric motor which as a result reduce emissions standing cars in cities. The electric motor is powered by lead-acid battery and a rapid discharging and reducing battery life. To extend the life developed additives to the electrolyte. In the thesis, these additives investigated. If they really have a positive effect on the battery.

Parking house of NPP Dukovany
Okounová, Kateřina ; Rosendorf, Aleš (referee) ; Boleslavská, Yvona (advisor) ; Matějka, Libor (advisor)
The theme of this thesis is the design of two parking houses, which will be made in stages in the area of the Dukovany nuclear power plant. The construction site is located directly in the Dukovany NPP site, south of the cooling towers, which do not interfere with the area in any way. North of this area is a commercial area and bus station, which is separated from the land by buildings and greenery. The five-storey parking houses will not disturb the surrounding character of the buildings. Cooling towers have a big influence on this and they are unmistakable by their height and the designed objects will not have a massive effect next to these towers, they only complement the surrounding buildings. The buildings are designed of regular shape. A more prominent feature on these buildings will be the front facade itself and the glass staircase spaces. The main entrances to the building will be marked with a light sign “P1” and “P2” for better orientation between buildings. The layout of the parking house "S01" in the first stage is designed using two ramps located in the middle of the building. There is also a station for charging electric cars, bicycle storage, sanitary facilities, cleaning room and TZB room. The stairwells are designed in three places for easier access of people. The parking function is complemented in the 1st floor with 6 self-service car wash boxes, which are only accessible from outside the building due to the wet use process. The second stage of construction is considered to be the same layout, the entrance to the second building "S02" is designed from the west side.
