Center of Gravity Measurements of Bicycles
Burda, Ondřej ; Bradáč, Albert (referee) ; Panáček, Vladimír (advisor)
The first part of the thesis The measurement of the location of centre of gravity of bicycles is firstly about history and division of bicycles, about the legislation in the Czech Republic concerning the cyclists, about the analysis of accidents of cyclists and lastly about the analysis of the method of the measurement of the location of centre of gravity. The second part of the thesis describes the procedure of calculation of the location of centre of gravity in the chosen incline method and the proposal of measure apparatus. The third part of the thesis occupies with the measurement and processing of concrete values for chosen sample of cyclists on the bicycles which are selected in the way that the results of the location of centre of gravity in the final part of the thesis are compared with the respect to their application during the expert opinion.

Diagnostický systém elektrických aktuátorů turbodmychadel
Posádka, Jakub
This master’s thesis deals with the creation of a diagnostic system concept for measuring the parameters of electric actuators of turbochargers. This concept is based on a review of the current measurement methodology in the company, which deals with the development and testing of turbocharger actuators, presented in the author's bachelor's thesis. The aim of the thesis is to create a design of a measuring system operated during mobile measurements and then to carry out experimental measurements. The first part of the thesis describes the design research of electronic turbocharger actuators. In the second part are presented the construction of the measuring device and the methodics. The output of the experimental measurement is the evaluation of selected parameters that are crucial for measuring the properties of the actuators. In the conclusion, the identified weaknesses are mentioned and recommended for modification for future use.

Monitoring the electricity consumption of the building
Franěk, Vít ; Bátora, Branislav (referee) ; Janík, Daniel (advisor)
The thesis deals with the issue of metering devices in buildings that provide instant and cumulative information for electricity providers and consumers. This information is provided by individual metering devices in order to reduce costs and optimize energy consumption. The thesis presents a theoretical analysis of the metering devices and their subsequent practical use for metering and evaluation of the results with recommendations for consumers.

Textile electrodes in ECG measurement
Kocum, Filip ; Vélim, Jan (referee) ; Cupal, Miroslav (advisor)
This semestral thesis deals with the issue of electrocardiogram measurement and heart rate detection using textile electrodes placed on the body. One of the main tasks was to design the possibilities of attaching the sensors to the body in order to ensure the best possible adhesion to the skin. The work focuses on the design of suitable electrode placement in terms of functionality and stability of measurement. Furthermore, the work focuses on the comparison of textile and Ag / AgCl electrodes. The last point was the design of a preamplifier for measurement and its subsequent implementation.

The dam Letovice - the design of the reconstruction of the technical surveillance system
Vahalík, Zbyněk ; Špano, Miroslav (referee) ; Říha, Jaromír (advisor)
This bachelor thesis deals with the design of the reconstruction of the technical surveillance system of the dam Letovice. The introductory part describes the area of the dam, dam's surroundings and the dam itself with the particular objects. The subsequent section describes the technical surveillance system and a list of existing measuring devices with description. This is completed by the measurement results of the technical surveillance system from previous years. Additionally, it also contains the list of devices, which will be removed during the reconstruction. The final part deals with the design of the new technical surveillance system, list of measuring devices and their characteristics.

Control of HVAC equipments
Zaoralová, Kateřina ; Weiglhofer,, Willy (referee) ; Rubina, Aleš (advisor)
The aim of the diploma thesis is application of the topic Control of HVAC equipments. The thesis is divided into three part – A, B, C. The first theoretical part deals with controlling/regulation in general, it focuses on controlling/regulation of HVAC equipments and it describes ways of air volume flow measurement, which relates to the third experimental part. The second part is focused on design of HVAC system in inpatient ward and fit-out for employees. In the third part was realized verification of air flow volume controller in two chosen buildings, whence in one there weren´t fulfilled manufacturer´s requirements and in the second one they were fulfilled. In conclusion there were compared measured values.

Problems of measurement and evaluation of switching loop impedance
Švéda, Miroslav ; Bárta, Jan (referee) ; Veselka, František (advisor)
This work is applied to questions about impedance of tripping loop. It deals with problems of measuring impedance of tripping loop, different measurement, procedures and accuracy of these measurements. Further, the work deals with the subsequent evaluation of the measuring impedance of tripping loop and writing of the measurement results. The work also focuses on the impedance of tripping loop in terms of the operation of the protective elements of the electrification system. Finally, the practical measurement of the impedance of tripping loop in real electrical circuits is performed as part of the work.
