Failure rate wastewater treatment plants
Boryśová, Michaela ; Vlčková, Veronika (referee) ; Hluštík, Petr (advisor)
This thesis deals with the sludge management in wastewater treatment plants. It provides a basic overview of methods for modifying risk material in sludge ending. The main goal of this work is to create a fault trees based on faults which occurred in the sludge management facilities. Furthermore, it was created frequency of failures assessment of the objects on wastewater treatment plant in Hodonín. Provided information were obtained during excursions of WWTP Hodonín and Zbýšov.

Tube microphone preamplifier
Čacký, Adam ; Hruboš, Zdeněk (referee) ; Brančík, Lubomír (advisor)
The theme of the master´s thesis is design a microphone preamplifier which uses vacuum tube as a main amplifying element. Part of the work is theoretical assumptions for the optimal design and implementation of peripheral involvement, comparing the properties of components used and the resulting parameters of modeled device. The thesis also includes a proposal of the source unit for supplying all parts of the preamplifier. The results are accompanied by circuit simulations and laboratory measurements of the main parameters of the designed device.

Heat insulating moulded refractory concretes
Bednárek, Jan ; Bartoníčková, Eva (referee) ; Šoukal, František (advisor)
The thesis deals with the possibility of specific weight lowering of kaolin suspensions using air-entraining agents. These agents are usually used as concrete admixtures. The goal of the thesis is to verify an alternative possibility of creating porous structure in kaolin suspensions in order to prepare heat insulating moulded refractory concretes without using lightweight fillers. The effect of several air-entraining agents was compared, after that the dosage of agent and mixing conditions were optimized. The stabilization of prepared foams and practical application of selected agents were also part of the thesis.

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.

Design of control system of two wheels mobile robot
Robenek, Vít ; Kovář, Jiří (referee) ; Houška, Pavel (advisor)
The aim of this bachelor thesis is to design control system of a two-wheel mobile robot and to subsequently implement this system using available sensor devices and National Instruments’ Single-Board RIO platform. The introduction briefly describes the general issue of two-wheel mobile robots as inverted pendulums, followed by an overview of several existing solutions to this problem. The following describes used robot including description of its parts and its mathematical model. Then the main part of the work follows, which is design of the sensory and control system. At the end of the thesis, the implementation is described along with evaluation of the stabilization system results.

Electronic stability systems
Musil, Jan ; Ambróz, Richard (referee) ; Zháňal, Lubor (advisor)
In this Bachelor’s thesis there are basic electronic stability systems described. These systems are mostly used as a precaution in safety of the traffic, but also to ensure comfort of the crew. The main part of the thesis is focused on systems ABS, ASR and ESP. The other parts aim to describe additional systems, which are still in development. In the end there is also view of various individual car companies and possible steps in the future.

Use of Bank stabilization
Neuvirt, Petr ; Pelikán,, Petr (referee) ; Šlezingr, Miloslav (advisor)
The main topic of this bachelor thesis was to suggest biotechnical stabilization on choosen locality of water reservoir Seč. This locality was endangered and damaged by abrasion. The water reservoir is situated in Pardubický region, district Chrudim. This thesis included geodetic measurement, hydrotechnical calculation and in the end of the thesis several suggestions of possible biotechnical stabilization on choosen locality.
