ESP/ESC Impact to Behavior of Vehicle
Weigel, Filip ; Mrázek, Vojtěch (referee) ; Strnadel, Josef (advisor)
This bachelor thesis focuses on active safety - ESP. System ESP greatly improves stability of vehicle while turning. The thesis analyses modelling, brake functionality, subordinate systems of ESP - ABS and ASR, physical forces and phenomenons, model example, analysis of problem, design of model, implementation of model and experiments evaluation of implemented model in UPPAAL enviroment. The goal of the thesis is to prove that ESP system helps to stabilize vehicle while turning by simulation of vehicle model. Results are presented in well-aranged graphs side-by-side. It is possible to analyze the behaviour of vehicle while turning with ESP or without ESP.

Manufacture of centrifugal Castings from iron and non-iron alloys
Žanda, Miroslav ; Kaňa, Václav (referee) ; Cupák, Petr (advisor)
The thesis describes and characterizes the foundry method of centrifugal casting, which was established in the 16th century. Based on a literature study of centrifugal casting and centrifugal force, the principle of centrifugal casting is described. Centrifugal casting can be divided according to the position of the axis of rotation to horizontal and vertical or by the method of right centrifugal casting, semi-centrifugal casting, centrifugal casting, or Tekcast method. The most basic and most common centrifugal casting product is a pipe. The pipe production is progressing from material melting, pre-operation machine preparation, casting and solidification of the melt, to adjusting and finishing of the pipe. We can cast centrifugally a several of materials, especially steel, cast iron, copper, zinc, aluminum and titanium. Centrifugal casting can also cast multilayer castings.

Construction of reversible swirl turbine
Kosar, Jakub ; Štégner, Ladislav (referee) ; Haluza, Miloslav (advisor)
The thesis deals with the construction design of reversible swirl turbine used in a tidal range power plant for bidirectional operation. The theoretical part provides an overview of state-of-the-art technologies in the usage of tidal energy, mostly by means of tidal range and stream tidal power plants. It also analyses respective designs of tidal turbines and their advantages and disadvantages. The practical part of the thesis demonstrates individual steps applied when examining loading forces and also shows the design method and strength inspection procedure of the turbine and its parts, especially of the impeller, gears, shafts and bearings. Lastly, the paper outlines the selection approach of the most appropriate water plant generator.

Damage correspondence of car hit by the fragments of roofing
Prnka, Jiří ; Sedlák, Robert
The article deals with the traffic accident with supposed contact of a car with fragments of roofing, which were lost from an oncoming truck, and caused subsequent running off a car into a ditch. Based on correspondence damage, mechanism of damage and movement of fragments of roofing it was researched if the question could arise as mentioned accident plot, as it was described by the participant.
