Design and construction of an interactive light sources panel
Žák, Martin ; Pavelka, Tomáš (referee) ; Škoda, Jan (advisor)
This semestral thesis deals with design and construction of the interactive light sources board and measurement of various parameters of those light sources. Using the given requirements, a solution is worked out (construction materials, behaviour, design, wiring etc. are given). Based on this, the interactive board was also constructed and put into operation. The thesis is also focused on the given light sources themselves (incandescent light bulbs, halogen lamps, compact fluorescent lamps, fluorescent tubes and LED lamps) and their measurement results are presented.

Measurement of elektrical and nonelectrical quantities of motor drive for switchgear
Pěček, Dominik ; Dostál, Lukáš (referee) ; Valenta, Jiří (advisor)
Bachelor’s thesis deals with measurement of electrical and non-electrical quantities on motor drive MP-BD-X230. As an introduction the classification of drives for switchgear is analysed and circuit breaker BD250 is described. Thesis continues by explaining application, basic nature and design solution of motor drive MP-BD-X230. Another step is description of workplace and devices which will be used for measurement. Measurement procedure of electrical and non-electrical quantities is also carried out accompanied by evaluation of measurement. Final part of the work deals with calculation of uncertainty of measurements with a reference to each individual measurement calculation and also deals with determination of measurement errors.

High precision differential thermometer
Sieklik, Ivan ; Wilfert, Otakar (referee) ; Barcík, Peter (advisor)
This work describes the principles of measurements of refractive-index structural parameter. This parameter represent intensity of atmospheric turbulence which is measured by a differential temperature meter. Basic properties of atmospheric transmission environment are specified and their influence on optical wave is stated. Furthermore, this thesis also describes fundamental types of sensors dedicated to temperature measurements. The aim of this work was to create a differential temperature meter which is able to measure the refractive-index structural parameter.

SHORTING DEVICE DRIVE OPTIMALIZATION
Michalík, Marek ; ABB, Drahomír Tůma, (referee) ; Dohnal, Petr (advisor)
Tato bakalářská práce se zabývá optimalizací pohonu zkratovače ve vysokonapěťovém rozváděči ve spolupráci s firmou ABB s.r.o, pro kterou je tato práce zpracovávána. V první části se zabývá teoretickým rozborem spínacích přístrojů se zaměřením na bezobloukové spínací přístroje, kam patří i zmiňovaný zkratovač. V dalším textu jsou aktuální informace o teorii elektrických pohonů, které jsou později využité v praktické části. Podrobněji se práce zabývá teorií stejnosměrných strojů zejména motorů s permanentními magnety, jelikož tento druh motoru je použit i v pohonu, který pohání použitý zkratovač. V další části je rozebrán celý pohon a všechny jeho části, několik odstravců je věnováno i výběru druhu optimalizace a zhodnocení současného stavu pohonu se zaměřením na jeho chyby a nedostatky. Jsou popsány parametry současného motoru a převodovek. V praktické části se dá nalézt protokol o zkoušce zkratovače, která proběhla v ABB s.r.o. V poslední části je k dispozici protokol z měření současného stavu nezatíženého pohonu. Jsou podrobně rozebrány a porovnány možnosti optimalizace pohonu. Všechna nabízená řešení byla důkladně konzultována se zástupci a techniky z průmyslových firem.

Evaluation of user interface COMES
Škoda, Pavel ; Štohl, Radek (referee) ; Pásek, Jan (advisor)
The bachelor thesis deals with analysis of user interface of system COMES. Its aim is to create a study with user feedback regarding this system. Then the system COMES can be improved based on obtained information. Firstly, there are written information about designing the correct user-friendly interface focusing primarily on easy operation and communication with user. Subsequently methods of measuring user interface are divided and described. In the second part, questionnaire was made up. It helps users test system COMES and evaluates this information. The most important part of this thesis is the last chapter. It describes the possible improvements of the existing system which eliminate identified deficiencies.

Measurement of precise capacitance decade in environmental chamber
Schinneck, Jakub ; Bartoň, Jan (referee) ; Havlíková, Marie (advisor)
This bachelor’s thesis deals with the control capacitance decade in a climatic chamber. The theoretical part introduces a capacitance decade M525 of the MEATEST company and the program Caliber of the same company. It introduces the methods of capacitance measurement. In the bachelor’s thesis there is the calculation of the uncertainty of measuring devices. On the basis of the lowest uncertainty, we choose the most suitable measuring device. The practical part describes the measuring with the use of prepared procedure for verification of the capacitance of programmable decade. The last part contains the evaluation of the measurement results and their comparison with the manufacturer's specifications.
