Utilization of light emitting diode lighting
Podola, David ; Černý, Michal (referee) ; Paloušek, David (advisor)
This bachelor thesis deals with problems of illumination by LED diodes. Basic concepts of lighting technology are defined in the first part. The second part is dealing with the construction of body LED diodes and explains the principle of white light formation to LED. Introduces problems of cooling. Gives an overview of the available power sources for LEDs. Provides an overview of how to control lighting by using motion sensors and presence sensors. Will be made basic economic balance sheet, which will evaluate the advantages of using LED sources. Attachments provide the LED catalogs of manufacturers, accessories for LED and comment on other sources of information.

The methodology of using digital tachograph data for forensic engineering purposes
Zeman, Petr ; Kledus, Robert (referee) ; Drahotský, Ivo (referee) ; Doupal, Emil (referee) ; Libertín, Josef (advisor)
Control authorities and experts in their practice come across digital tachographs. Digital data is an important source of relevant input data and informations needed for in depth road accident analysis. In practice, it is possible to encounter an existing negative phenomenon, an unauthorised access to and fraudulent manipulation of the tachograph´s data. False data has a major impact on the results of the accident investigation and analysis. Control authorities and experts should be prepared for such cases. This thesis describes the different types of manipulation of Digital Tachograph records and the ways of their detection. Tachograph manipulation is a nowaday issue. It is very important to deal with this problem. For the reasons mentioned above I have set up a Data Control Procedure Standard for control authorities and experts and drafted technical requirements for future generation of tachographs.
