Wireless thermostat
Králíček, Martin ; Viščor, Ivo (referee) ; Kincl, Zdeněk (advisor)
The Master’s thesis discusses wireless thermostat for a control boiler. In order to complete the project we have to design and realise the whole project with software design. The system contains two units, a master control and a measurement of regulation units. The project initially talks about regulation of heating systems for family houses and larger buildings like schools and stores for example. Next, the project describes the control and regulation units and their potential extension for effective and economical operation. Both units are equipped with microcontrollers, which these control each of function. The communication between both units is provided by wireless interface in free radio band ISM. There is a user interface for the master control unit’s regulation process. The measurement and regulation unit has only the possibility to switch between manual and automatic control for regulation of heating system.

The design of fountains system
Müller, Patrik ; Štigler, Jaroslav (referee) ; Haluza, Miloslav (advisor)
The goal of this thesis is to design the fountain system. Nozzles have to squirt to the same height. Flow has to be the same on each nozzle and it has to be done for our given dimensionsThe right pump has to be chosen, but it cannot be done without proper knowledge of theroy of hydrodynamic resistence, basic hydromechanics and characteristics of the valves.

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.

The Delivery of the Mixture Containing Abrasive Particles.
Hrabina, Martin ; Sluše, Jan (referee) ; Štigler, Jaroslav (advisor)
The aim of this bachelor thesis is focused on description of the transport equipment parts used in some industries for delivering of the mixture containing abrasive particles. The thesis is divided into some captures. Each of them deals with the transport issues. The first part of the thesis is focused on the flow of liquid in transport equipment. Second part describes particular parts of pumps and compares various kinds of them, highlighting their advantages. One of the significant topics of the thesis is the characterisation of pipeline using for the above mentioned transport.

The influence of decreasing of impeller diameter, change Q - Y characteristic
Hyriak, Maroš ; Habán, Vladimír (referee) ; Haluza, Miloslav (advisor)
The purpose of the thesis is to familiarize with the fundamental characteristics of ta centrifugal pump while changing geometry of the output section of its impeller trimming. Characteristics of a pump is calculated whilst diameter of the impeller is changed. More specifically, changes in the flow and energy are observed while diameter of the impeller is decreasing. Two possible solutions, approximate and accurate, are offered for both parameters. The thesis suggests that an application of the approximate solution is satisfactory for the flow calculation of the impeller. In contrast, for the energy calculation is the approximate solution sufficient only in case of the slight trimming. Increase in the trimming results in the drop of the hydraulic efficiency and decrease in the accuracy of the results. Consequently, the accurate solution is recommended for the energy calculations. Limitations of the paper may be represented by two facts. First, in comparison with the calculations, results are in reality affected my numerous variables that have not been included in the calculations due to their unpredictability. Second, calculations were based on the several assumptions that are rarely met in the reality. The results of the thesis are applicable in the every-day life when adapting the pump to the customer needs.
