Systematics of records and management of stable serial parts for control of functional test stations
Hamr, Zdeněk ; Mach, Miloš (referee) ; Juřica, Pavel (advisor)
This thesis deals with the design of single record keeping and management of stable serial parts that can be used for checking functional test stations. The work contains one main proposal and two other proposals resulting from the goal of introducing single record keeping. The work is divided into three main parts. The first part is theoretical, dealing with theoretical concepts. The second part focuses on mapping the method of recording meters, stable serial parts and the software environment. In the third part, a solution to the single record keeping based on the analytical part is proposed.

Device for Measurement of MacPherson Strut Friction
Čapek, Štěpán ; Blaťák, Ondřej (referee) ; Hejtmánek, Petr (advisor)
This thesis focuses on the development of a device for measuring friction in a MacPherson strut. The thesis describes the mechanical friction that arises in the contacts of individual parts of the strut. It also includes a description of the MacPherson suspension and its comparison with other types of wheel suspensions, quantification of the forces acting on the strut during standard vehicle operation, and, last but not least, the design of a device for measuring increased friction in the strut when it is subjected to lateral force. The conclusion of the thesis describes the results of FEM (Finite Element Method) calculations of stress and deformation of the device, which verify the final design.

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.

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.
