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.

Design of a device for measuring the center of gravity height of road vehicles
Hanych, Jaroslav ; Blaťák, Ondřej (referee) ; Vančura, Jan (advisor)
This master's thesis deals with problems connected with measuring vehicle centre of gravity height. The research part summarizes generally known methods of measuring vehicle centre of gravity and moments of inertia. Essential part of this thesis is the design of a device for measuring the centre of gravity height of a road vehicle on a principle of measuring a period of oscillation. The height position of the platform of the device is adjustable through hydraulic cylinders. A stress-strain analysis of the design was executed through a combination of analytical methods and a finite element method. The process of measurement was described and an equation for determination of centre of gravity height was deduced. Error of measurement was estimated based on the knowledge of partial errors of measured values.

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.
