Stabilizing systems of passenger cars
Odehnal, Jakub ; Vopařil, Jan (referee) ; Kučera, Pavel (advisor)
This Bachelor’s thesis describes basic stabilizing systems of passenger cars. These systems are correcting driving the cars and improve safety of the traffic. The main systems described in this thesis are ABS, ASR and ESP. There are also summarized some other assistant systems. In the end there is also view of various individual car companies and their theories of stabilizing of cars.

Strengthening of vaulted structures by prestressing
Požár, Michal ; Solař,, Jaroslav (referee) ; Drahorád,, Michal (referee) ; Klusáček, Ladislav (advisor)
The topic of this Ph.D. theis is repairing and strengthening of historical wagon vaults (barrel vaults, tunnel vaults) using post tensioning with tendons (monostrands) in longitudinal direction. The vaults should be without an edge, that´s mean the baroque vaults are well appropriate for this method. The pointed barrel vault should be problematic. The stabilization is for a wagon vault created by semicircle or segment part of a circle as well as an elliptic shape. The study has been made for vault with a width of 1 m and for the prestressing force has been used one tendon only. Of course, this method could be apply for normal constructions with a width of many meters. In this case, more tendons should be use with a suitable spacing. The goal of this work was to monitor an experiment model of an wagon vault and a real strengthened baroque vault of a church in Švábenice. During the monitor time, the static Analysis has been made. For these analysis appropriate finite elements in Ansys program has been use. The results of this work is to amplify the knowledge of the real behaviour of strengthened vaults, which could be use like instruction for the civil engineers. Further the public information guide to build an appropriate model of an Vault with an interaction with post-tensioning tendons.

A draft amendment selected section of of the watercourse
Vyplel, Adam ; Blahuta, Jaroslav (referee) ; Šlezingr, Miloslav (advisor)
The bachelor thesis focuses on the draft amendment of the selected section of the Veverka watercourse in the cadastral area of Brno-Bystrc in the km 0,632 to 0,918 of watercourse. The adaptation is mainly done as a draft for the stabilization of damaged banks by means of stone retaining wall, wooden pole fencing, stone riprap and gabions. The suitability of the given measures was determined on the basis of the current state of the watercourse. In the chosen section there is a sedimentation reservoir with a boulder chute that has been subjected to an assessment of the stability of the slope surface. Then the HEC-RAS program is used to verify the flow capacity of the whole flow channel for the one-year flow Q1 condition. Subsequently, the vegetation accompaniment and the coastal vegetation of the selected section of the watercourse were designed in order to naturally connect the watercourse to the surrounding forest vegetation.

Stabilization of bank of river
Odehnalová, Zuzana ; Ing.Pavla Pilařová (referee) ; Šlezingr, Miloslav (advisor)
The aim of this work is to design stabilizing the banks of the watercourse Svratka in the cadastral Tišnov. The chosen site was divided into ten sections. Each segment was classified in terms of the status of riparian vegetation. Stabilizing elements are designed in three sections chosen location, where banks are most stressed. In other parts do not necessarily represent a significant stabilization measures. The result is a proposal biotechnical stabilization, completed the design of riparian vegetation.

Temperature stabilization system
Brtáň, Filip ; Kuchta, Radek (referee) ; Kadlec, Jaroslav (advisor)
This project deals with design of universal system for temperature stabilization using a Peltier device, controlled by microcontroller. The result of this work is an autonomous equipment with automatic tuning of regulation constants, calculation of temperature stabilization limits, possibility of setting required modes and with interface for connection to PC. The regulator stabilise temperature with an accuracy of 0,1 °C within the range of temperature from 0 to 60 °C.

Bank stabilization of Brno Dam
Václavovský, Filip ; Pelikán, Petr (referee) ; Šlezingr, Miloslav (advisor)
The aim of this bachelor‘s thesis is to design stabilizations of the banks of the Brno‘s water reservoir, damaged by abrasion. This work is focused on the most damaged Osada area located on the left bank. Shore abrasion is caused by fluctuations in water levels and the effect of wind waves. Result of this thesis are biotechnical stabilizations, which has to stop or slow the symptoms of abrasion.

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.
