Compensation of Temperature Instability of the Received Signal Level of Microwave Links
Repa, Pavol ; Musil, Petr (referee) ; Bubniak, Milan (advisor)
This thesis deals with the field of microwave links. Specifically, it is concerned with compensating for the temperature instability of the received signal level of microwave links. This problem is solved according to the proposed algorithm, which can be used to suppress the temperature waveforms, and thus achieve better results in the calculation of collisions in the Telcorain software application. A compensation algorithm has been developed to compensate for microwave links with strong temperature dependence. By~compensating for these non-compliant microwave links, it was possible to reuse them in the calculation of the average rainfall intensity, and hence they were retained in~the~generation of the 2D rainfall maps. The compensation algorithm is implemented in the~Telcorain application, where the individual results of the precipitation calculation can be verified. Throughout the thesis, microwave joints from two manufacturers, each with a~different technology used, were analysed. Their comparison with each other is~the~focus of this thesis, in which the individual differences between these microwave links are published.
Staniční hlášení na modelové železnici

The goal of this thesis is to create automatized station annoucements for a railway model. The theoretical part describes station annoucements on real railway and possibilities of generating such annoucements for the railway model. The practical part is focused on creating a system for creating automatised station annoucements for railway model based on options provided by laboratory focused on controlling railway vehicles. The system of station annoucements is successfully connected to existing technology hJOP. The system is based on commands from hJOPserver.
Preparation of MgO-Ni3Fe nanocrystalline composite from spark eroded powder
Schneeweiss, Oldřich ; Jirásková, Yvonna ; Řepa, P.
Nanocomposites MgO-TM (TM = Ni3Fe, FeCo) were prepared by controlled heat treatment of compacted spark synthesised nanopowders. Main attention was paid to study of influence of interaction with surrounding atmosphere and adsorbed gases on phase composition and magnetic properties. Mössbauer spectroscopy, x-ray diffraction and TEM were used for phase analysis. Changes in structure and phase composition during annealing were detected using thermomagnetic curves and DTA/TG measure-ments and completed with gas analysis using mass spectroscopy.
