Analysis of technologies for quality of services assurance in packet networks
Kulhány, Andrej ; Kouřil, Jiří (oponent) ; Hošek, Jiří (vedoucí práce)
This bachelor thesis focus on analysis of technologies for guaranted quality of services in packet network. In main part I devote to detailed study of technologies IntServ and DiffServ. Practical part of my bachelor thesis includes design of network in simulating program Openet Modeler. Designed network is pecialized to guarantee quality of services during voice transmission by technology DiffServ. When designing the network I simulated guarantee of services in network without quality of service and in network with quality of services technology DiffServ. Finaly I compared issues of simulations.

Investigation pressure effect on lead-acid accumulator lifetime for hybrid electric vehicles.
Kulhány, Andrej ; Bilko, Radek (oponent) ; Bača, Petr (vedoucí práce)
The thesis is focused on remitting lead-acid segments of partial charge mode which simulates the conditions in HEV. The experimental cells were submitted to different pressures on the electrode system. The main aim of the thesis was to minimize the irreversible sulphating of the negative electrodes, which are in the PSoC regime limiting in the overall life of lead-acid accumulators. All cells were submitted to measurement of the negative electrode potentials, resistance of active materials, contact resistance of the grid – the active material and measurements of pressure changes during three PSoC cycles.
