Multi-Resolution Cepstral Features for Phoneme Recognition Across Speech Sub-Bands
(IEEE, 1998)Multi-resolution sub-band cepstral features strive to exploit discriminative cues in localised regions of the spectral domain by supplementing the full bandwith cepstral features with subband cepstral features derived ... -
Observation of an anchoring transition in a discotic liquid crystal
(EDP Sciences, 1998)We report the anchoring transition in a discotic liquid crystal, hexapentyloxytriphenylene (HPT), from edge-on to side-on alignment in a discotic phase. The topology, easy direction of orientation and the coating of the ... -
The investigation of the relaxation processes in antiferroelectric liquid crystals by electro-optic spectroscopy
(American Institute of Physics, 1998)Electrooptic spectroscopy of an antiferroelectric liquid crystal is carried out over a range of frequencies from 1 Hz to 100 kHz. In the antiferroelectric SmCA phase two relaxation processes are found, one at the fundamental ... -
Rotational bias of an antiferroelectric liquid crystal studied by polarized Fourier transform infrared spectroscopy
(1999)Experimental studies of the absorbance vs polarization angle of the incident ir beam on a cell have been carried out for several absorbance bands in the SmA phase and in electrically induced ferroelectric states F(1) and ... -
A model for human skin impedance during surface functional neuromuscular stimulation
(IEEE, 1999)A new mathematical model for the bulk electrical impedance of human skin is presented. In particular this model describes the impedance of skin during surface functional neuromuscular stimulation (FNS) with square stimulation ... -
Molecular dynamics of iso-amyl bromide by dielectric spectroscopy, and the effects of a nonpolar solvent, 2-methylpentane, on the spectral features
(American Institute of Physics, 1999)To gain insight into the effects of the weakening of the electrostatic interactions on molecular dynamics when polar molecules are dissolved in a nonpolar solvent, the dielectric polarization and relaxation behaviors of ... -
Fast high quality interpolation of missing data in image sequences using a controlled pasting scheme
(IEEE, 1999)An important topic in image restoration is interpolation of missing data in image sequences. Missing data is a result of dirt on film and of ageing processes where the film contents are replaced by data that bears little ... -
Removal of line artefacts for digital dissemination of archived film and video
(IEEE, 1999)Line scratches are a common form of degradation in archived motion picture film. The automatic restoration of such, material has become of increasing interest in the last few years with the rase of consumer digital video ... -
Adaptive noncontact gesture-based system for augmentative communication
(IEEE, 1999)An adaptive noncontact gesture-based system for augmentative communication is described. The system detects movement of any anatomical site through the analysis of reflected speckle. This movement is converted into ... -
Discriminitive Multi-Resolution Sub-Band and Segmental Phonetic Model Combination
(2000)A joint discriminative framework for multi-resolution sub-band HMMs and a hybrid segmental phonetic model is presented which combines independent likelihood scores using class dependent weightings trained to a minimum ... -
Ferrielectric liquid crystal subphase studied by polarized Fourier-transform infrared spectroscopy
(American Physical Society, 2000)IR dichroism and the structure of a homogeneously aligned cell of a chiral smectic antiferroelectric liquid crystal (R)-1-methylheptyl 4-(4?-dodecyloxybiphenyl-4-ylcarbonyloxy)-3-fluorobenzoate [with acronym (R)-12OF1M7] ... -
The exponential dielectric relaxation dynamics in a secondary alcohol's supercooled liquid and glassy states
(2000)To gain insight into a recent observation that the prominent, Debye-type relaxation process observed for a primary alcohol may not be the a-relaxation process associated with molecular diffusion of a liquid @Europhys. ... -
Thermally activated escape rates of uniaxial spin systems with transverse field: uniaxial crossovers.
(American Physical Society, 2000)Classical escape rates of uniaxial spin systems are characterized by a prefactor differing from and much smaller than that of the particle problem, since the maximum of the spin energy is attained everywhere on the line ... -
Nonlinear impedance of a microwave-driven Josephson junction with noise
(American Physical Society, 2000)The nonlinear impedance of a point Josephson junction is calculated under various conditions for the resistively shunted junction model in the presence of noise. The calculation proceeds by solving the Langevin equation ... -
Alignment instability caused by anchoring of the in-plane directors to the rubbing direction in the V-shaped switching
(2000)In order to investigate the molecular alignment in the smectic liquid crystals showing the V-shaped switching behavior, two types of the liquid crystal cells, a sandwiched cell and an open cell, were prepared. ... -
Small planar monopole covers multiband BRANs
(2000)The use of a single antenna which can cover a wide range of frequencies is a desirable feature for future wireless communications systems. The emerging self-organising and ad-hoc networks require more than an octave ... -
Field-induced phase transitions in an antiferroelectric liquid crystal using the pyroelectric effect.
