We have studied the effect of isotopic substitution on the superconducting T sub c in the 90K superconductors Ba sub 2 YCu sub 3 and Ba sub 2 EuCu sub 3 O sub 7 by replacing O sup 16 with the heavi
In the IST (Information Society Technologies) project FITNESS: Fourth-Generation Intelligent Transparent Networks Enhanced through Space-Time Systems, the issues of re-configurability with Multiple
This article explores the recently issued ITU-T G. vector (G.993.5) {[}1] that allows expanded use of 100 Mb/s DSL. A tutorial description on G.
This article explores the recently issued "G.vector" (G.993.5, [1]) ITU-T standard's significant expansion of 100 Mb/s DSL use.
We have discovered a highly collimated optical jet emanating from a faint star and pointing towards the Herbig-Haro object HH 34.
To decode a baseband data waveform, a clock signal giving the proper sampling time must be available.
In most instances a data system designer is faced with the problem of transmitting through a noisy channel over which he has no control.
We consider the problem of routing high-speed, time-multiplexed packets of information from N inputs to N outputs by means of a centrally located digital switch.
The stalloy pole pieces used in this instrument are polarised by a large permanent magnet, an armature being suspended centrally in the air gap, so that it is only subjected to a magnetic pull when
This paper presents the Koreasat 5 secure communication system that has been design and developed by Alcatel Alenia Space - Italy (AAS-I) for Agency for Defense Development - South Korea.
