Construction of The GPS device
Hlaváč, Libor ; Macháň, Ladislav (referee) ; Šteffan, Pavel (advisor)
The goal of this thesis is a complete design and realization of a device that is able to communicate with GPS module iTrax300 and display the coordinates received from the module. The thesis deals with the GPS, localization principles and the standard communication protocol for navigation systems - the NMEA 0183 protocol. Futhermore it is dealing with the particular steps in the realization of the engineered device (from the specification of requirements at the beginning to the testing of its functionality in the end). The GPS coordinates, the Coordinated Universal Time (UTC), the date, the altitude and the speed on the ground can be displayed. There is also a possibility to put in any coordinates, the direction and the distance to the point are displayed afterwards. The device enables the track storage in the memory as well. The track is viewable while connecting the device and the PC through the USB interface.

THE INFLUENCE OF CONSOLIDATION PROCEDURE PARAMETERS ON COMPACTION OF AL POWDER
Lowe, T. C. ; Kunčická, L. ; Kocich, R. ; Davis, C. F. ; Hlaváč, L. ; Dvořák, Jiří
The influence of different consolidation procedures on compaction of Al powders was evaluated. Powder preparation procedures consisted of selection of particle size distribution, cold isostatic pressing (CIP), and vacuum sintering. Processing parameters investigated included the number of compression steps, compression pressure, and sintering temperature and time. Densities of the samples after compression and also after sintering were measured and compared. The overall oxygen content was analysed using by Energy Dispersive Spectroscopy. Phase composition was determined using X-ray. Microhardness measurements were performed to evaluate the degree of compaction. Double-step CIP at 200+300 MPa and subsequent sintering at 500°C for 60 min produced the best combination of properties from all the consolidation technologies of Al particles. Of the particle size ranges studies, those with diameters between 20 and 45 μm produced the best results. Aluminum oxide was present in the structure after all the processing treatments.

Comparison of Continuous High-Pressure Generated and Pulsing Low-Pressure Generated Water Jets on Concrete
Mádr, V. ; Sitek, Libor ; Hela, R. ; Hlaváč, L. M. ; Bodnárová, L. ; Pustelník, J. ; Janurová, E.
The concrete samples with various erosion states were disintegrated by pure continuous water jets generated from pressure 380 MPa in the Liquid jet laboratory at the VŠB - Technical University of Ostrava. Simultaneously, the identical concrete samples were tested by pulsing water jets generated by low pressure 30 MPa in the Department of Material Disintegration at the Institute of Geonics of the AS CR. The erosion states of samples were prepared by application of several laboratory techniques simulating the concrete aging under the natural conditions due to the real applications in practice. They were prepared at the 127 Institute of Technology of Building Materials and Components of the Brno University of Technology. The influence of the erosion state on the disintegration rate was tested and the surface topography was studied. The comparison of both the depth of penetration and the volume disintegration ratio regarding the input power is performed.
