Effect of lubricant rheology on lubrication film thickness.
Prášilová, Alena ; Šperka, Petr (referee) ; Křupka, Ivan (advisor)
Lubrication is a very important part of mechanical engineering, which ensures high lifetime of machine parts, reduction of friction and wear and also it leads to decreasing of power consumption. In this bachelor`s thesis there is described rheology of newtonian and non-newtonian lubricants and its effect on lubrication film thickness. Measured central film thickness values are compared with theoretical prediction.

Local Ventilation
Bilík, Martin ; Otáhal, Jan (referee) ; Krejčí, Vladimír (advisor)
This bachelor thesis deals with local ventilation, especially a variant of the local exhausting. At the start of work shall indicate the reasons why it is ventilation very important. There are listed some requirements for ventilation of technical and legislative terms. Ventilation systems are analyzed by several criteria in the next part. The next chapter of this work is devoted to systems and methods of local ventilation. In one chapter is made and a description of the distribution parts of the ventilation system. The last chapter deals with designing and using exhaust adapters. There is also made comparison of their parameters, which represent the operating costs associated with using these adapters.

Gravital conveyor for transport
Fatka, Milan ; Pokorný, Přemysl (referee) ; Kašpárek, Jaroslav (advisor)
The aim was to propose a conveying gravity path for the transport of steel casting in the context of inter-transfer service. The conveyor is dealt with valid norms with regard to simplicity of design, production and assembly (disassembly) with broad use of standardized parts. It was also seen to be done to take advantage of the proposal in solution of similar specification.

Design of electric tackle
Bádr, Miroslav ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
Purposes work was create technical documentation to an electrically driven tackle with actuated by hand undercarriage. Was booked up fundamental parameters like bearing, stroke and hoisting speed. First was effected calculation of load on pinion necks and an idle pulley. Subsequently was effected calculation for right election of a rope, an idle pulley, a rope drum and bearings for the rope drum. Up this calculation followed calculation for a right election of an electric motor and a shaft clutch. The documentation was complemented with pictures and tablets, that are seted near single decisive knots of the tackle. To the documentation was creationed how a suggested arrangement drawing so single subassemblies drawings.

Analysis of traffic lanes joining processes
Mikolášek, Igor ; Všetečka, Martin (referee) ; Holcner, Petr (advisor)
The aim of this paper is to analyse the behaviour of the traffic flow at an area of merging traffic lanes where an application of the zip rule is expected, accoding to the law no. 361/2000 Sb. “o provozu na pozemních komunikacích”. Žabovřeská street, part of the VMO Brno, in the direction from Královopolské tunely to Hlinky interchange was chosen for observation and measuring. Observation, first-hand measurement, radars, and other available means were used for data collection. On the basis of data analysis, several suggestions for improvements are made. These are aimed at increasing the bottleneck capacity. One of the suggestions is tested in a simulation program Aimsun.

Speed Increasing for Track Section Bojkovice-Bohuslavice nad Vláří
Ptáček, Jiří ; Hoza, Miroslav (referee) ; Svoboda, Richard (advisor)
This thesis will examine possibilities of increse speed on a railway track section between Bojkovice - Bohuslavice nad Vláří. The increase of speed will examined according to contemporary geometric parameters of the railway track and with proposed changes of geometric parameters of the railway track. The proposed changes cannot profoundly transformate the body of the railway track. In both cases a restriction of speed by level crossing, a track branching ect. will be taken into consideration or will propose changes of these objects.

Design and verification of training sprinter
TŮMA, Pavel
The goal of the diploma thesis is the design of a training program for sprinters and verification of the training by physical metrics. Experiment is method, which was used in this work. The experimental and testing period lasted from February to June 2013. In the theoretical part, we present the history of sprinting, the various sprinting disciplines, the means of energy supply for sprinting performance and training for the various disciplines. In the practical part, we deal with development of the training plan and evaluation of this plan. Analysis of the results then confirms the hypothesis. There have been improvements in tests of speed, power, reflexes and endurance following the training program. Training plan was successfully authenticated.

Comparing motional abilities of Czech streethockey extraleague players
GÄRTNER, Tomáš
The aim of this bachelor?s theses is to find out the level of motional abilities of the Czech streethockey extraleague players with the help of the standardized tests. The testing battery contains two tests for speed and two tests for endurance. All players are to pass the tests in the end of summer preparation when they can show the highest level of performance. All trainers will get a special form where they will have to pud down all data necessary for the bachelor?s theses. All information will be processed and compared. In the end the work will confirm or disprove predetermined hypotheses.
