Application of Flaw Detection Method for Surface Quality Inspection
Smutný, Daniel ; Pernikář, Jiří (advisor)
When processing materials, there are a number of factors which influence the final quality of products. The possibility of defects occurrence, both sub-surface and surface ones, is one of the factors. In the precision engineering production, the automotive, bearing or aerospace industry in particular, no level of defects is tolerable. The thesis deals with the causes and consequences of the occurrence of such defects, and the methods for their identification. For this purpose, a new contactless optical method for the fully automatic inspection of the surface defects has been developed by Mesing, spol. s r.o. In order to verify the performance of the aforementioned method, four specific products have been tested by the author using the method. Finally, there are examples of the successful implementation of the automatic machines, for a design of which the results of the model testing were utilized.

Human detection using laser rangefinder
Němeček, Jakub ; Selingerová, Simona (referee) ; Krejsa, Jiří (advisor)
This thesis describe dynamic obstacle detection and move tracking. Detection is based on laser rangefinder data. Tracking is based on compare two scans. Algorithm of localization method is processed in Matlab. In Matlab is also made simulation of scanned data. Filter parameters are tested and optimalized on this data.

Falšování masných výrobků
Ambrožová, Hana
The diploma thesis is focused on issues connected with falsification of meat products and methods to detect this type of falsification are mentioned in the thesis, as well. Food falsification is a problem, which has persisted since the Middle Ages. A break authentisity doesn't appear only in meat products but also in all commodities. Surveillance authorities, whose job is to check food are described in the thesis. Meat products from the point of view of their break authentisity are discussed in more detail in the thesis. High pressure liquid chromatography, enzyme-linked-immunosorbent-assay, polymerase chain reaction belong to the most used detect methods of the food falsification. The practical part of the thesis contains determination of pure muscular proteins in durable and fermentated meat products by means of high pressure liquid chromatography. In the next part poultry masculature is determined in products using noncompetitive heterogeneous immunoassay, in which legislation bans using of mentioned type of masculature. In the determination of net muscle protein were found 7 of 25 samples (24 %) as unsatisfactory and in the determination of poultry muscle 4 of 24 samples detected (17 %) as unsatisfactory.
