Computer analysis of medical image data
Krajčír, Róbert ; Šmirg, Ondřej (referee) ; Uher, Václav (advisor)
This work deals with medical image analysis, using variety of statisic and numeric methods implemented in Eclipse and Rapidminer environments in Java programming language. Sets of images (slices), which are used here, are the results of magnetic resonance brain examination of several subejcts. Segments in this 3D image are analyzed and some local features are computed, based on which data sets for use in training algorythms are generated. The ability of successful identification of healthy or unhealthy tissues is then practically tested using available data.

Design of Measurement Net
Krajčír, Róbert ; Drexler, Petr (referee) ; Kadlec, Radim (advisor)
This thesis deals with transfer of measured data from sensors placed on pulse power generator for long distances in areas with strong outer interference. Main goal is to design fast and reliable network. Therefore some basic transfer methods, which are available for usage, are analyzed. Regarding to the characteristics of these methods, the most suitable option was chosen, which is analog fiber optic link. In the next phase, the concept of the network itself is dealt with, including analysis and choice from variety of modulation techniques, transmitters and recievers and their characteristics. Variety of drive and amplifier circuits are also mentioned, with emphasis on their influence on transfer and noise attributes and available bandwidth. Based on theoretical analysis and component pros discovered, exact parts are chosen and complete concept of the network is established, including auxiliary circuits. According to this concept printed circuit boards for both transmitter and reciever are made and tested.
