GNSS Deformation Measurement of Railway Structure
Buday, Michal ; Bureš, Jiří (referee) ; Švábenský, Otakar (advisor)
The purpose of this thesis is to evaluate the train bridge shift using the satellite geodesy methods. Introductory part of the thesis is devoted to GNSS basis. The following part discribe work with commercial software Leica Geo Office. Results of calculations were transformed to local topocentric frame. In this frame were compared differencies between GNSS meassurment and classical terrestrial methods. Part of this thesis is to consider tropospheric refraction influence based on used tropospheric model. The end of this thesis is devoted to consider hypothesis that reference point which was considered as solid does not show trend of changing it's location. For this purpuse BERNESE GPS Software was used. GNSS meassurments were linked to the nearest points of permanent GNSS networks. Results are documented numerically and graphically.
Modular shift of a polynomial matrix using Matlab
Hurák, Zdeněk ; Šebek, Michael
Efficient algorithm for modular shift of a polynomial matrix is proposed in this note.The algorithm avoids any iteration that is inherent in standard Euclidean algorithm for division of polynomial matrices.It assumes that the denominator polynomial matrix is row-reduced.If it is not,it can always be transformed into row-reduced form accepting some additional computational cost. Numerical experiments with an implementation of the proposed algorithm in Matlab are reported.
