Experimental validation of active flow control concept for automotive applications
Sobotka, Vojtěch ; Jebáček, Ivo (referee) ; Popela, Robert (advisor)
Tato diplomová práce obsahuje komplexní návrh systému aktivního řízení proudu instalovaného na osobním voze Škoda Roomster. Tato práce navazuje na výzkum provedený VUT a TUB na vozidle Volkswagen UP! Návrh lze rozdělit na tři základní části - návrh spoileru, návrh závěsů a návrh vyfukovacího systému. V každé z těchto částí je návrh detailně popsán a potřebná výkresová dokumentace je součástí práce v její příloze. Pro potřeby návrhu vyfukovacího systému bylo provedeno jeho testování. Výsledky testu jsou v této části uvedeny. Práce také obsahuje komplexní popis sestavení celého systému a jeho instalace na automobil.

Design of pneumobil driven by pneumatic motor
Podhorský, Petr ; Robenek, Dětřich (referee) ; Nevrlý, Josef (advisor)
Master thesis deals with design of "student" pneumatic car equipped by pneumatic elements of a chosen firm. The introductory part is devoted to mapping the Hungarian competition. The idea of designing such vehicles comes from this competition. Next step is analysis of vehicles that are present in this competition. The main part describes the development of vehicle from the initial design, through analysis of main components, through to the production and presentation. The work contains a strain-stress analysis of the frame which is made by using the finite element method. The work ends with the conclusion which assesses the results.

Analysis of the Production of Pressure Vessels
Schiller, Pavel ; Jaroš, Aleš (referee) ; Kalivoda, Milan (advisor)
The thesis deals with the optmization of the manufacturing process of pressure vessels. Primarily, the thesis is focused on optimization of bottom and throat forging operations, because only these operations must be performed in a three-shift system, unlike the other operations that are performed in a two-shift system. After the analysis, the inefficient operations have been identified and the goal was to eliminate them. We have found a solution to this situation as an automation of the critcal operation. We have compared the present and proposed solution by capacity calculation. Subsequently, the technical- economic evaluation has been performed which was a basis for the determnation of investment return related to the automation of the critical operation

Breathing Apparatus equipment in the Units of the Fire Rescue Service of the South Bohemia Region
SOKOL, Karel
The Fire Rescue Service of the Czech Republic is one of the fundamental components of the Integrated Rescue System. Its overall development and modern equipment allows for a very effective way to provide assistance in all types of emergencies. The breathing apparatus equipment is one of the many parts of the common personal protective equipment that allows firefighters to remain within even a stifling environment. The aim of this thesis was to make a full analysis of the numbers and the range of age in use of these kinds of breathing apparatuses and cylinders, which belong to the units of the equipment in the Fire Rescue Service of the South Bohemia Region. Furthermore, I have made a comparison between the two basic types of air breathing apparatuses that are being used, in terms of the protection period, which have been provided to the users (carriers). The participants of this inquiry were members of the FRS of the South Bohemia Region, which include the separation of chemical and technical services into the various local departments. I have received the data from twenty different fire stations in total. In the questionnaire which was given, I collected the data from the respondents, according to their age and added the number of different types of breathing apparatus and cylinders and period or time of use to this study. The data was collected during February and March 2010. Hypothesis 1: the number of pieces of the breathing apparatus equipment in the South Bohemia Fire Rescue units is sufficient; this was confirmed. The result has been compared with the numerical data collected from the indicated positions in the current legislation set to 1.7 times of the number of the members serving in one inning. Hypothesis 2: that these breathing apparatuses meet the requirements of all of the current legislation; this has not been confirmed. The result shows a comparison of the technical parameters of the instruments and technical conditions, as reported by the Interior Ministry decree No. 255/1999 Coll. as amended, regarding the technical conditions kind of fire. The results will be used to establish the financial balance sheet and the planned purchases of the pressurized breathing apparatus equipment and the used variations of the composite cylinders.
