Housing for seniors
Vrbický, Josef ; Donaťák, Vladislav (referee) ; Donaťáková, Dagmar (advisor)
The subject of the diploma thesis is the design of a new building of a free-standing building for housing for the elderly, in the form of project documentation for the construction. The building is designed brick with monolithic reinforced concrete ceilings. Perimeter masonry is designed from ceramic brick blocks th. 300 mm supplemented by contact insulation system ETICS th. 200 mm, which will be provided with silicone plaster with a grain size of 1.5 mm. The internal load-bearing masonry is designed from acoustic ceramic brick blocks of thickness 250 and 300 mm. The partitions are designed from acoustic partitions. The ceilings are designed with a heavy floating floor with excellent acoustic properties. The roof above the two-storey part is designed as a single-skin flat with extensive greenery. Above the three-storey part is a hipped roof made of lattice trusses and sheet metal roofing. The windows are designed with plastic insulating triple glazing. The balcony railing is designed for aluminum with safety glass filling. The building is heated by a gas boiler and controlled ventilation is designed throughout the building using a central recuperation.

Apartment house
Vrbický, Josef ; Donaťák, Vladislav (referee) ; Donaťáková, Dagmar (advisor)
The subject of the bachelor thesis is the design of a new building of a detached apartment building in Holice, in the form of project documentation for construction. The building is designed with bricks and ceilings made of beams and ceramic inserts. The peripheral masonry is designed from ceramic brick blocks th. 300 mm completed with contact insulation system ETICS th. 200 mm, which will be equipped with silicone plaster 1,5mm. The internal load-bearing masonry is designed from acoustic ceramic brick blocks th. 250 and 300 mm. Partitions are designed from acoustic partition walls. On the ceilings, a heavy floating floor with excellent acoustic properties is designed. The roof is designed flat single-skin with thermal insulation of mineral wool and with waterproofing layer made of bitumen modified SBS strips laid in two layers. Balcony railing is designed aluminum with safety glass paneling.

The influence of alcaline accumulators loading on their parameters
Čech, Ondřej ; Vrbický, Jiří (referee) ; Sedlaříková, Marie (advisor)
This master's thesis deals with alkaline battery characteristics and it has special consideration of nickel-cadmium cells. There are three main experimental parts in this paper. First one is concerned with positive electrode materials properties and is aimed to investigate impact of magnesium ions formed into nickel hydroxide electrode structure. Second part deals with battery charging/discharging and response measurement tool design. National Instruments hardware PXI modules for data acquisition was used and program in LabView environment was made. Last one is concerned with nickel-cadmium cell properties changes during increased temperature stressing. Investigation of cell self-charge changes during lithium hydroxide addition into electrolyte was made.

Fuel for internal combustion engines
Vrbický, Jiří ; Jedelský, Jan (referee) ; Štětina, Josef (advisor)
This thesis is concerned with basic features of fuels for internal consumption engines, especially their influence on thermal efficiency. It also introduces dividing of fuels and their compare in ecologic, economic and technologic side. It is concerned convectional fuels (gasoline, diesel oil) and alternative fuels (nature gas, bottled gas, hydrogen, biodiesel, biogas, methanol and ethanol).

Properties electrodes materials for alcaline accumulators
Řihák, Lukáš ; Vrbický, Jiří (referee) ; Sedlaříková, Marie (advisor)
This thesis is involved in basical properties of electrode materials for alkaline accumulators. This thesis describes the possibilities of capacity stabilisation of nickel electrode to be stable for highest number of cycles. Thesis also consider modification of properties of electrode materials on the base of nickel hydroxide by using dopes (aluminum, manganese). Measuration proceeded on the thin film electrodes created by electrodeposition. Measuration of properties of electrodes proceeded by cyclic voltammetry and frequency analyzis.

Design of air conditioning system of a flat
Vrbický, Jiří ; Zerzaňová, Alena (referee) ; Hejčík, Jiří (advisor)
The diploma thesis is consisting of theoretic part, which deal with used ventilating systems, ways of waste heat recovery and describe basic types of air-conditioning systems. Following part attend to design of ventilating system and multi-split air-conditioning system for flat. Part of design of ventilation system is calculation of noise levels in rooms. Air-conditioner design is based on calculation of thermal stress. Annual demand of cold and heat demand are calculated using TRANSYS software. Design documentation is part of the diploma thesis.

Influence of Al ionts in nickel hydroxide on behaviour of electrodes
Růžička, Tomáš ; Vrbický, Jiří (referee) ; Sedlaříková, Marie (advisor)
This master's thesis is concerned with the influence of aluminate ions added in various concentrations into the structure of nicel hydroxide that creates Ni-Cd accumulators positive electrode active mass basis nowadays. Nicel hydroxide occurs in two basic modifications ? and ß. Nowadays used ß modification reaches low capacity in comparison with ? modification. The disadvantage of ? modification is its instability and gradual degradation to ß modification. The aim of this diploma paper is to select the optimal amount of aluminate additives into the structure of nicel hydroxide with regard to electrochemical efficiency, stability, and degradation degree of the accumulated layer.
