A Preliminary Study of Modification of 7-Deazaadenine with a Complex of Osmium Tetroxide with 2,2 '-Bipyridine
Vítová, Lada ; Havran, Luděk ; Fojta, Miroslav ; Šedo, O. ; Zdráhal, Z. ; Vespalec, Radim
Reactivity of a purine nucleic base analogue 7-deazaadenine (A*) in short oligodeoxynucleotide (ODN) towards an osmium tetroxide complex with 2,2'-bipyridine (Os, bipy) was investigated by means of electrochemistry, capillary electrophoresis and MALDI-TOF mass spectrometry. Electrochemical measurement, electrophoretic analyses and mass spectrometric analyses of reaction mixture proved that ODN with an A* residue yields an osmium adduct with properties similar to those exhibited by the well-known adduct of thymine.
Workplace for testing of the photodiodes
Šedo, Ondrej ; Poliak, Juraj (referee) ; Wilfert, Otakar (advisor)
This paper is focused on design of the workplace for measuring basic parameters and characteristics of standard photodiodes. There is also experimental test of its possibilities and comparison of the measurement results with the catalogue data. It also includes elaboration of an algorithm that processes the measurement data into visual presentation.
Communication protocols for Free-Space Optical links
Šedo, Ondrej ; Kincl, Zdeněk (referee) ; Kolka, Zdeněk (advisor)
This master’s thesis is focused on behaviour of the TCP/IP protocol on free-space optical link which is affected by the effect of atmospheric turbulence. This causes fluctuation of the received optical power and therefor bit error rate changes. In the simulation model short-time bit error rate is calculated from random generated received optical signal and then used in time-domain analysis of the OMNeT++ network simulator. A buffer in transmitter is designed based on simulation results. It pauses the data transmitting in cases of FSO link outage. This method is then implemented into FPGA device.
