Controlled power generator of current impulses
Gabriel, Viktor ; Vrba, Kamil (referee) ; Rampl, Ivan (advisor)
The goal of this thesis is to design and realise microprocessor-controlled generator of current impulses, which are being brought in induction load. Thesis contains description of individual functional generator parts, mainly microprocessor program equipment. The text also aims for inductor design as an induction load and other solutions of power parts with the selection of the most suitable one. The generator of current impulses itself is realised on two-sided printed circuit board.

Possibility of Measurement Automation
Ilichman, Ondřej ; Košíková, Jana (referee) ; Vdoleček, František (advisor)
The thesis is focused on the automation of measurement with the using of hardware and software. Efforts to objectification processes and eliminating human influence on the outcome are increasingly reflected in the technical fields of measurement. In this work, methods of measurement modification, transformation and subsequent analysis of the measured quantity are discussed. Since nowadays it is possible to automate nearly all types of measurement, it is shown, under what circumstances is appropriate to use automated measurements. The final section is devoted to solution of software and hardware design for measuring temperature in the server room. They are proposed 3 possible solutions and on the basis of their analysis the optimal variant is chosen.

Measuring of Velocity Profiles in Liquids by Using of UVP
Kárník, Jan ; Stejskal, Jiří (referee) ; Štigler, Jaroslav (advisor)
The following bachelor's thesis deals with one possible way of determination velocity profiles in liquids. Content of the thesis is focused mainly on the method of the UVP (Ultrasound Velocity Profile), on the ways and principles of measuring, on its pluses and cons and it´s comparison with the other conventional methods, like for the example the PIV (Particle Image Velocimetry) and LDA (Laser Doppler Anemometry). There is also the possible placement of the transducers to the measuring system discussed. Furthermore the thesis deals with trouble in the test measurement. At the beginning this work deals with familiarization with principle and function of the measuring device and with the device for the method UVP itself. Apart from the UVP measuring method the thesis also deals with short description of the competitive methods – PIV, LDA, which are used to measure the velocity profiles nowadays. Particular attention is given to the PIV method, which significance is currently growing. In conclusion, there is comparison of different methods with the UVP method made and there are the future steps to realize the successful measurement with UVP method also discussed.
