Solving of off-gas cooling system for removing contained solvents
Blažek, Pavel ; Kilkovský, Bohuslav (referee) ; Jegla, Zdeněk (advisor)
Diploma thesis deals with searching of the most appropriate solution of air mass cooling to clear away contained solvents. The solution is based on real and operated pharmaceutical unit. The cooling system is solved as systém of three tubular heat exchangers. In the first heat exchanger the air mass is cooled down by water, in the second by ice-cold water and brine R32 is used for cooling in the third heat exchanger. Heat exchanger system is solved for cooling the air mass which results in condensation of contained solvent – acetone.

Price Comparison of an Apartment Building in Brno According to the Valid Valuation Regulations
Blažek, Pavel ; Superatová, Alena (referee) ; Pertl, Marek (advisor)
hesis deal with a question, how can change the price of the apartment building on the basis of legal act such as a statement of the owner of the building, without any changes in the building construction or technical conditions. Apartment building valuation was done by two methods which used the legislation for real estate valuation. The first method was the valuation of the apartment building as a unit and this method used the combination of expenses and revenues. The second method was the valuation of the individual flats by comparison and sum them up. Results showed, how big can be the difference between this two methods in the valuation the same thing.

Determination of device geometrical misalignments influence on dimensional measurements in X-ray microcomputed tomography
Blažek, Pavel ; Klapetek, Petr (referee) ; Zikmund, Tomáš (advisor)
Tato práce se zabývá geometrickými nepřesnostmi v geometrii rentgenového počítačového tomografu (CT přístroj). Především jejich vlivem na výsledky metrologických měření a metodami kterými lze tyto negativní efekty eliminovat. V práci jsou prezentovány výsledky simulací CT měření v softwaru aRTist při kterých byli nastavovány nepřesnosti v pozici detektoru a osy rotace vzorku. Ukazuje se tak, které geometrické faktory mají na měření největší vliv. Praktická část se pak zabývá CT přístrojem HeliScan, který využívá unikátní rekonstrukční algoritmus k eliminaci geometrických nepřesností. Jsou vyvinuty referenční objekty (pláty s rubínovými kuličkami a zirkonová koule), které splňují požadavky normy VDI/VDE 2630 1.3. na testování metrologických schopností přístroje. Objekty vhodné pro měření ve větším zorném polem byly vyrobeny, zkalibrovány a otestovány v CT měření.

Determination of measurement uncertainties of holes in steel components by X-ray computed tomography
Blažek, Pavel ; Šperka,, Jiří (referee) ; Kalasová, Dominika (advisor)
This thesis deals with determination of uncertainties of dimensional measurements in X-ray computed tomography. CT measurement process involves a lot of steps and is affected by a lot of factors, which depend not only on the CT system parameters but also on the measured sample and the operator. All of this influences the resulting uncertainty. Experimental method involving calibrated workpieces allows to determine the uncertainty without perfect knowledge of the influence factors. This method is described in standards ISO 15530-3 and VDI/VDE 2630 2.1. The aim of this work is to experimentally determine the uncertainty of tomographic measurement of dimensions of holes of selected workpiece on a CT device GE phoenix v|tome|x L240. Hence, a demonstration workpiece has been designed and manufactured. The dimensional CT measurements of inner and outer diameters have been performed on this sample. The reference measurement has been performed using a length measuring machine SIP 1002. The uncertainty of measurement depending on penetration thickness of the material has been determined.

Methods of environmentally friendly carcass disposal
Blažek, Pavel ; Kropáč, Jiří (referee) ; Novotný, Pavel (advisor)
In the thesis we deal with a summary of all available methods of disposal of environmentally friendly vehicles that are currently available. Addressing this problem is to find appropriate procedure, thereby simplifying and reducing the cost of processing vehicles. We also deal with this issue in terms of legislative, therefore a summary of the law on dealing with waste vehicles. The aim of this work is to introduce the methods of processing whole vehicles as well as various parts of cars and find the most appropriate methods of disposal
