Stabilization systems of motorcycles
Honek, Bohumil ; Tobiáš, Martin (referee) ; Zháňal, Lubor (advisor)
In terms of this bachelor’s thesis, the author created a comprehensive overview and description of mechanical and electronic stabilizing systems of one-track vehicles. This thesis furthermore deals with the impact of a vehicle’s structure on its stability and riding dynamics and also includes a brief historical development of the individual components. This thesis then offers an outlook into the close future of vehicles’ and similar machinery’s stability, followed by the author’s critical evaluation.

Design and construction of sensing part of the cimbalon
Nop, Patrik ; Vrba, Kamil (referee) ; Jirásek, Ondřej (advisor)
This term paper focuses on the design of several possible methods of electroacoustic transduction (further called pickup), specifically of virtual strings of the electronic cimbalom. The paper is based on the problems associated with the classical cimbalom’s design, as well as with its method of tone production. For each of the proposed methods I have made use of my own experiences with guitar pickup, laser harp function, MIDI controller capabilities, and the properties of electret microphones. Most of the methods are ones that I developed and tested in practice, some of which I am still working on and will include in my subsequent Bachelor’s thesis.

Design of dynamic models for traction control of experimental vehicle
Jasanský, Michal ; Porteš, Petr (referee) ; Grepl, Robert (advisor)
The Master's thesis deals with the simulations kinematics and dynamics of experimental four-wheeled vehicle with all-wheel steering and all-wheel drive. Suggestion of vehicle stability systems ABS/ASR for traction control is included. There are several dynamics models with their comparison. The estimation of important vehicle parameters is implemented. Based on knowledge the simple vehicle stability system ABS/ASR is created.

Crankshaft mechanism of Stirling engine
Valčík, Martin ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
This diploma thesis is focused on the design of the driving mechanism of Stirling engine, where was chosen modification of these engines with rhombic drive. Subsequently is constructed kinematical, dynamical and thermomechanical mathematical model. Finally, is going from these models for execution strength control and drawing documentation.

Measurement of Inertia properties of bodies for the purpose of mathematical modeling of vehicle dynamics
Dvořák, Karel ; Laurinec, Marián (referee) ; Porteš, Petr (advisor)
The aim of the diploma thesis is to create a concept of methods that can be used for measurement of important mechanical inertia properties of bodies -- the coordinates of center of gravity and the the moment of inertia tensor, in case we don't have 3D model of these bodies. The thesis divides this problem into several sub-problems and suggests the solutions for each of them. Required equipment was created and measurement was carried out. At the end the measured values are compared with the teoretical ones and accuracy of this method is determined.

High Frequency Pulsation of Water Turbine in Operation
Kubálek, Jiří ; Kozubková, Milada (referee) ; Hružík, Lumír (referee) ; Haluza, Miloslav (advisor)
This thesis is concentrated on mathematical modeling of high frequency pulsations in pump turbines, which are the source of high-cycle continuous stress of the spiral casing cover, wicket gates and runner. There are proposed the solutions using the transfer matrix for the tube with a constant and conical cross-section. The paper compares variations of cylindrical and conical tubes, changes in boundary conditions. There are the models of PSPP Dlouhé Stráně made only of cylindrical tubes comparing to the model with cylindrical and conical tubes

CITY HALL - RES PUBLICA, The administrative center of the district of Brno-sever
Tománková, Michaela ; Rudiš, Viktor (referee) ; Oplatek, Jiří (advisor)
The subject of the diploma project is the design of new townhall building of district Brno – The north. The townhall is designed at the place of existing barracks and the urbanistic plan of whole area was the previous school work. The townhall as a new centre of the district is dominant in its location, the main motive is openness and permeability. The volume is created from two basic cubes with offices which define public space between with indoor public square and specific volumes of halls in dynamic composition. Communication structure is formed by footbridges and staircaises connecting all volumes. The building combines reinforced concrete and steel structure and is covered by glass shell around.
