Noise and artifact suppression in fMRI data based on multi-echo data and independent component analysis
Pospíšil, Jan ; Gajdoš, Martin (referee) ; Mikl, Michal (advisor)
The main task of this work is to design an algorithm for suppressing unwanted noise and artifacts in fMRI data using the analysis of independent components and multi-echo data. The theoretical part deals with the basic principles of magnetic resonance, including construction and image data processing. The practical part presents a pilot design of a method inspired by a professional publication in the Matlab software environment, where this design is subsequently tested on real fMRI data provided by the Laboratory of Multimodal and Functional Imaging, CEITEC MU.

Multimedia Transmission in MPLS Network
Vlček, Lukáš ; Novotný, Vít (referee) ; Polívka, Michal (advisor)
Thesis introduces positive traits of MPLS technology comparing to other transportation mechanisms in WAN environment, refers to its cons. The next section of thesis describes fundamentals of routing and switching in MPLS trying to make accent of different methods between routing in IP network and MPLS network. Following part focuses on topic about Traffic Engineering, its methods and practices. Another part of thesis is about Traffic Engineering in MPLS and its posibilities of controling data flow. Last section describes planning, implementation and operation of experimental MPLS network. Conclusion summarizes achieved results and sets further goals to complete whole fulfillment of thesis assignment.

Measurement of electro-optical properties of quantum-size structures based on InAs/GaAs - photocurrent and electroluminescence
Mačkal, Adam ; Hazdra, P. ; Hulicius, Eduard ; Oswald, Jiří ; Pangrác, Jiří ; Melichar, Karel ; Hospodková, Alice ; Šimeček, Tomislav
Contribution presents the electroluminescence, photoabsorption and polarization properties of semiconductor lasers with thin strained InAs layers in GaAs at elevated temperatures. The lasers exhibit high optical recombination efficiency, low threshold current density and wide temperature operation range (above 100řC).
