Lead-acid baterry charger with automatic cycle
Moravec, Pavel ; Friedl, Martin (referee) ; Steinbauer, Miloslav (advisor)
The lead-acid batteries are still important and very often used type of battery even in 21st century. This project is focused on development of charger, which provides fast, but save charging of batteries with respect to maximum life time and reliability. The developed system uses constant current charging and constant voltage charging methods. It's specialized in charging batteries with liquid or gel electrolyte and traction types of batteries, which works with 12 V value of voltage. It's able to charge safely the deeply discharged batteries and when battery is unpluged for a long time, it can keep its capacity at maximum level too. The charger can choose optimal charging process according to the discharged level of battery. Each charging phase is interpreted by light signals and the achievable charging current is 20 A.

Low specific speed pump working in turbine mode
Bezdíček, Jiří ; Moravec, Prokop (referee) ; Štefan, David (advisor)
The use of the pump in turbine mode is an evolving area. For this reason, research of less standard pumps from the edges of the specific speed spectrum is suitable for this purpose. This diploma thesis was focused on the influence of splitter blades on the exclusively turbine mode of a low specific speed pump. CFD calculations of the pump were performed, considering the sidewall gaps between the stator and the rotor. CFD served not only to obtain turbine characteristics but also to describe the flow and analysis of other phenomena, such as volumetric efficiency or hydraulic forces.

Multifunctional house
Moravec, Pavel ; Javůrek, Tomáš (referee) ; Brukner, Bohuslav (advisor)
Specified bachelor thesis deals with an insulated newly built family house for four to five-member family with added polyfunctionally in the form of project office. Proposed construction is situated in the developable area of peripheral town part of Pelhřimov, southeast part of the town on the land number 2050/174. The proposed new building facility of a family house is a two-storey building consisting two rectangles inset into each other and with a double garage. The object is set into the sloping terrain so that the main entrance to the family house is in the level of the second aboveground floor where there is an entrance hall with utility room, a garage and relaxation, quiet and night zone located. From the level of the second aboveground floor it is possible to descend into the ground of the first aboveground. The ground floor serves as a space of residential area and daily and active space. In the level of the first aboveground floor there is the multifunctional part (project office) situated. It has separate entrance from the level of the first aboveground floor. The object is based on foundation walls and the spreading concrete slab on which the structural system walled of ceramic blocks will be based. The circuit construction will be complemented by contact insulation system ETIC made of breathable grey polystyrene. The ceilings are ferroconcrete and monolithic. There is a single-flat roofing with river-washed stones. The part of the thesis is the assessment of the object from the viewpoint of the thermal properties and processing of the solutions to fire safety construction.
