Non-intrusive estimation of speech quality is a challenging problem in that the estimation has to be performed without the original reference speech signals.
In order to estimate the quality of degraded speech processed by communication networks, conventional objective speech quality assessment methods require source speech signal, which has been applie
HBr inductively coupled plasma (ICP) etching is investigated to realize ridge laser waveguides on InP and GaAs substrates.
Critical current densities and resistivities were measured in a single crystal of the high-T sub c superconductor Bi sub 2 Sr sub 2 Ca Cu sub 2 O sub 8 within the ab basal plane (||) and along the
Surface morphology of high mobility heterostructures is examined and correlated with d.c., transport.
We have performed both in-plane and out-of-plane infrared reflectance measurements on the layered metal 2H-NbSe2, in a broad frequency and temperature range.
We discuss a generalized waveplate hinge model to characterize anisotropic effects associated with the hinge model of polarization-mode dispersion in installed systems.
We have studied for the first time effect of an applied magnetic field on the tunneling current flowing perpendicular to a weakly coupled multiquantum well structure.
We investigate effects of lateral confinement on spin splitting of energy levels in 2D hole gases grown on {[}311] GaAs.
Planar-site sup 63 Cu nuclear spin-lattice relaxation data are presented for a magnetically oriented sample of YBa sub 2 Cu sub 3 O sub 7 microcrystallites at temperatures 86K
