We present information-theoretically secure schemes for sharing and modifying secrets among a dynamic swarm of computing devices.
The Queueing Network Analyzer (QNA) is a software package developed in the Operations Research Department of AT&T Bell Laboratories for doing performance analysis of systems that can be modeled
The principal and up to six higher order acoustic surface modes from CaF sub 2 films grown epitaxially on Si(111) have been observed using Brillouin scattering.
Cloud computing has become the new paradigm for computation and service delivery.
Directional transmission to Australia, India, South Africa, West Africa and Canada, the 5 zones of the British Empire, is used, the best wave-length being chosen according to distance and path cond
Broad band GaAs/Al sub x Ga sub (1-x) As quantum well infrared detectors grown by molecular beam epitaxy have been demonstrated which are sensitive over the lambda = 8-12microns atmosphere window s
By pumping a fiber in the anomalous group velocity dispersion regime with a color center laser, we generate femtosecond pulses with tau > ~ 100fsec covering a wide spectral range between 1.55 l
Eighty-nine 42.7 Gbit/s, 100 GHz-spaced WDM channels in a 72 nm seamless band were transmitted over 40 x 100 km of fibre using carrier-suppressed return-to-zero differential-phase-shift-keyed modul
A broad-band Mach-Zehnder-interferometer-synchronized flat-top arrayed waveguide grating is presented with a 0.5-dB bandwidth of 12 nm over 90 nm of spectral range and a central excess loss value o
Broad-hand and pulsewidth maintained wavelength conversion based on a nonlinear optical loop mirror (NOLM) consisting of l-km high-nonlinearity dispersion-shifted fiber (HNL-DSF) is realized in the
