  W referacie opisano próby implementacji protokołu Etherent nie tylko w sieciach lokalnych, ale również w sieciach dostępowych (Ethernet pierwszej//ostatniej mili - EFM) i rozległych (10 gigabit Ehernet - 10GE). Proponowane rozwiązanie EFM może stać się tanim szerokopasmowym alternatywnym rozwiązaniem dla DSL i modemów kablowych. Z kolei 10GE może być alternatywą lub uzupełnieniem zastosowań OC-192 SONET.

  Electrical properties of iron oxide nanostructures observed in silicate glasses and glass-ceramics were studied. Two different sets of glass samples were prepared. The first group of samples has the composition of (50 − 0.5x)SiO2–(50 − 0.5x)PbO– xFe2O3, where x = 15, 20 and 25 (in mol%). Composition of the second group was 50SiO2–(50−x)PbO–xFe2O3, where...

  The linear impedance spectra of iron–silicate–lead glass samples were measured in the frequency range from 1 MHz to 1 MHz and in the temperature range from 153 K to 423 K. The structure was investigated by means of XRD and atomic force microscopy. Local electrical and magnetic properties of the samples were tested with the aid of electrostatic force microscopy (EFM) and magnetic force microscopy (MFM). The obtained results show...
