Design of vacuum tube compressor for audio signal processing
Valach, Ondřej ; Vrba, Kamil (referee) ; Koton, Jaroslav (advisor)
The seminar work deals with the problem of compressors and compressor LA2A in general. It discusses terms associated with the dynamics of the signal. The first part of the text is centred on the theoretical introduction, which discusses the concepts associated with the dynamic of signals. There is explained the principle of compression and parameters that are associated with this process. The second part is devoted purely to construction of the compressor, which is based on a well-known type LA2A. It describes its individual parts and their interrelation. At the end of the text it is proposed the idea of adding two features beyond the original LA2.

Methodology of the measurement speed approach at jumping events
Wagner, Štěpán ; Feher, Jan (advisor) ; Hojka, Vladimír (referee)
Title: Methodology of the measurement of the speed approach at jumping events Objectives: The objective of this thesis is to provide the methodology of measuring the approach speed using a radar, a camera and a photocell. It also aims to compare the individual devices for measuring the approach speed (the camera, the photocell, the radar) and to state their advantages and disadvantages. Last but not least, the thesis will define usage of data from measuring for the purposes of coaching practice. Methods: In my thesis I used the document analysis method. I used foreign publication as well as Czech literature as my sources. The foreign sources consisted mainly of specialized magazine articles or online publications focused on the topic of measuring the approach speed and the athletic event of jumping. As for the Czech literature, it comprised mainly of books about the athletic event of jumping. Gathered information was used during the experiment itself and during data assessment. Results: The difference among the individual devices can be clearly seen from the results, the recorded times differed by 0,01-0,02 s. The difference is noticeable even in the methodology of measuring and in data assessment. At the end, it was determined according to the coaching criteria, which device is the most suitable...

Photovoltaic Elements used in the Solar Energy and Testing of their Parameters
KUTTA, Jiří
Renewable sources of electric energy are currently being used. In the Czech Republic solar energy is especially used. This thesis contains theoretical description of physical principal, description of used photovoltaic modules and categorizing of modules according to applied production technology, description of measurements and measuring parameters of applied modules used in electric power production.
