Managing Planetlab nodes
Chupáč, Michal ; Balej, Jiří (referee) ; Müller, Jakub (advisor)
Bachelor’s thesis is focused on maintaining and managing PlanetLab nodes from one place. Introductory chapter contains process of network access creation and other important information and guidance. Following part involves remote access thru command prompt by program CoDeploy. This program is used for parallel command execution and file upload to multiple nodes. The thesis contains installation and configuration manual for applications CoDeploy, Plush and Nebula, description of their functions and practical usage in PlanetLab network environment. Section about graphic user interface Nebula deals with module for XML application development. Part with PlMan software alternative for Windows is also completely made out. Ending of the thesis is focused on CoMon monitoring system, its functions, elements and practical application in network.

Virtual Access to Nodes in PlanetLab
Fic, Jiří ; Matoušek, Petr (referee) ; Ryšavý, Ondřej (advisor)
PlanetLab as a distributed systems testbed offers a unique opportunity for developing and testing new applications useful for future Internet. This work brings up a scheme and a solution of the problem with accessing PlanetLab by a larger group of students e.g. for the purpose of solving their courseworks. A designed system empowers its administrator to create and control virtual user accounts which provide possibility for all its users to connect to selected nodes in the PlanetLab.

Client/Server Application for Global Network PlanetLab
Sladký, Milan ; Ryšavý, Ondřej (referee) ; Matoušek, Petr (advisor)
Objective of this bachelor's thesis is to get acquaint with experimental network PlanetLab, its history, development, principle of its behaviour and usage of this network, for example for development of new network architectures. Program part of this bachelor's thesis consists of concept and implementation of suitable client/sever type application, which runs on PlanetLab network.

Correction of gradient pulse shape distortions in radial MRI
Vitouš, Jiří
This paper focuses on the optimization of gradient-pulse shapes in MRI measurement. The main topic investigated in this paper is optimization of slice-selective gradient, where imperfections may produce phase distortion in the resulting image and also signal loss in the acquired signal. A method for correction is proposed based on the Nelder-Mead algorithm followed by coordinate ascent search in the neighborhood of the found solution. The adjustment is evaluated using a simple Fast low angle shot (FLASH) sequence with radial readout. The results show a significant improvement in the Free induction decay (FID) signal magnitude, echo stability, and an improvement in the homogeneity of image phase.
