Architectural study of the cycling stadium / runway / Favorit Brno / on the open space in.
Lukeš, Jaroslav ; Hrabec,, Josef (referee) ; Šindlar, Jiljí (advisor)
This diploma thesis looks into the area for sport and recreation in Brno-Komárov. The main part is the project of new arena for track cycling for Favorit Brno. Part of the assignment is also the solution for urban plan and redevelopment of the large area in the south of Brno in city district Brno-Komárov. Urban plan design is framed as conversion of the whole space into sport activities area for broad public. The velodrome itself is based on the idea of a bicycle and its parts as architecturally interesting part of the building, in this case particularly lacing of a wheel. Stadium could become new landmark for its surroundings and draw attention of the general public.

Gearbox for portable power generator
Kolka, Roman ; Hubáček,, Tomáš (referee) ; Bradáč, František (advisor)
The submitted project deals with a complete design of a gearbox of a portable ground power generator designed for preflight preparation of helicopters. The gearbox has been designed to meet given specifications, which are based on required electrical parameters of the entire power unit and with regards to parameters of driving turbine engine. The introductory section deals with a kinematical design of transmission gears with regards to required parameters and design constraints. The kinematical design determines whole concept and resulting form of the gearbox. Next part deals with optimization of gearing, the design of wheel bearing, and design of oil system. The implementation part of the project consists in the engineering design of the gearbox, which was made in 3D environment Pro/Engineer. The design is reviewed and first operational results of manufactured and tested gearbox are discussed in the concluding section of this work.

Hydrobike - feasibility study
Kunovský, Lukáš ; Kárník, Jan (referee) ; Štigler, Jaroslav (advisor)
This bachelor thesis presents a project of hydraulic system which is intended specifically for bicycle drive and is realized through hydrostatic transducers. It gives information about necessary components and about the procedure of their selection. In this procedure it focuses particularly on weight reduction and loss minimization. Apart from the considerations as such, it also analyzes prior concepts and adopts suitable improvements from these. In the presented plan it demonstrates a method of effective verification of the real parameters of the whole as well as of the partial components.

LED bicycle lights
Čmelík, Matouš ; Patočka, Miroslav (referee) ; Huták, Petr (advisor)
In semester thesis i project bicycle lighting using LEDs that are powered from the alternator. The LEDs are powered also from battery, that is recharged while driving and when you stop it enable uninterrupted lighting. The concept is designed so that the final price is as low as possible. All things is designed to insert to the existing bicycle lightint on Eska or Favorit bicycle. The use of inverters ensures high efficienty of the whole concept. Using LEDs compare to standart solutions with bulbs is more efficienty to.

Analysis of potential active damping for vehicles
Svoboda, Jakub ; Houška, Pavel (referee) ; Hadaš, Zdeněk (advisor)
Diploma thesis deals with the issue of active and semi-active damping and its possible applications in the context of vehicles. The beginning of the document is focused on the actual state, major applications and patents in the field. As each of the individual ways of usage is relatively specific, the next part is aimed particularly at the damping unit of bicycle. Given the choice, real measurements and simulations were made in order to verify the applicability of such a device in practice.
