ON THE STABILITY OF TWO-DIMENSIONAL DISCRETE-SYSTEMS - COMMENT
(ISI Web of Science, 1981)This correspondence shows that independent necessary conditions and sufficient conditions for the asymptotic stability of two-dimensional discrete linear systems presented by Ahmed can be readily obtained from previous results. -
Online Parsing of Sports Coaching Video Through Intrinsic Motion Analysis
(2007)Automatic record and review of actions in sports training sessions is of great benefit to both coach and athlete. Many coaching sessions involve repetition of particular actions to hone technique, such as a swing from ... -
Optical characteristics of ordinary and tunable 1D Si photonic crystals in the mid-infrared range
(2005)Reflection spectra and photonic band gaps (PBGs) for periodic structures consisting of grooved Si infiltrated with nematic liquid crystals (LCs) E7 have been obtained experimentally and by simulation. Periodically grooved ... -
Optical confirmation of biaxial nematic (Nb) phase in a bent-core mesogen
(2009)A bent-core mesogen with different end groups has been studied for different surface conditions in both planar and homeotropic cells using techniques for measuring biaxiality and optical switching. Biaxial nematic phase ... -
Optical properties of diamond films grown by MPCVD method with alternating nanodiamond injection
(Society of Photo-optical Instrumentation Engineers (SPIE), 2005)Transparent polycrystalline diamond films with grain size ranging from a few tens to hundreds of nanometres were prepared on fused silica substrate by Microwave Chemical Plasma Vapour Deposition method (MPCVD). The ... -
Optical properties of grooved silicon structures: theory and experiment
(2011)The reflection spectra of grooved silicon structures consisting of alternating silicon walls and grooves (air channels) with a period of a = 4?6 ?m are studied experimentally and theoretically in the mid-IR spectral range ... -
Optical rotatory power of different phases of an antiferroelectric liquid crystal and implications for models of structure
(American Physical Society, 2001)The investigation of the antiferroelectic liquid crystal (AFLC) was presented. The crystal was found to possess different helical smectic phases identified through a texture under cross-polarizers with a homeotropic alignment ... -
Optical rotatory power, biaxiality and the models of the chiral tilted smectic phases
(2003)Among the chiral tilted smectics, the stable existence has been confirmed in numerous investigations of SmCA*, ~antiferroelectric smectic-CA) SmCF11* (SmCg*), SmCF12* ~antiferroelectric, AF! and SmC* phases. The structures ... -
Optical spectra of two-dimensional photonic crystal bars based on macroporous Si
(2011)Two-dimensional (2D) photonic crystal (PC) bars with 6 and 21 periods were fabricated by simultaneous photoelectrochemical etching of macropores and trenches in a pre-patterned silicon wafer. The structures had square ... -
Optical Study of Platinum-Modified Amorphous Carbon
(Fizika i Tekhnika Poluprovodnikov, 2009)Films of amorphous carbon a-C and a platinum-modified amorphous carbon composite a-C-Pt, produced by magnetron sputtering in a wide range of thicknesses and modifying platinum concentrations in the optimal mode for the ... -
Optimal Schemes for Motion Estimation on Colour Image Sequences
(IEEE Computer Society Press, 1997)This paper describes a method for incorporating the chrominance information when estimating the motion in a colour image sequence. It is based on a maximum likelihood formulation of the motion estimation problem which ... -

Orientation polarization from faster motions in the ultraviscous and glassy diethyl phthalate and its entropy
(2006)Dielectric spectra of the relaxation in glassy and ultraviscous liquid diethyl phthalate show that its relaxation strength , the distribution of times, and the relaxation rate are more sensitive to temperature T in the ... -
The orientational order and the dynamics of the dendritic liquid crystal organo-siloxane tetrapodes determined using dielectric spectroscopy
(2006)The dielectric measurements have been carried out on the two zeroth generation dendrimers with four branched arms (called tetrapodes) based on the siloxane cores. The results are analyzed in the framework of the molecular ... -
Orientational order of a ferroelectric liquid crystal with small layer contraction
(2010)We present spectroscopic and optical studies of a non-layer-shrinkage ferroelectric liquid crystal DSiKN65. The orientational order parameters S, measured with respect to the smectic layer normal using IR spectroscopy on ... -
Orientational/translational relaxation in aqueous electrolyte solutions : a molecular model for microwave/far-infrared ranges
(Royal Society of Chemistry, 2001)A model is given where the complex permittivity of an electrolyte solution is calculated as a superposition of the contributions due to the translation of ions and the reorientation of water molecules, which occur in ... -
A parametric feature extraction and classification strategy for brain-computer interfacing
(IEEE, 2005)Parametric modeling strategies are explored in conjunction with linear discriminant analysis for use in an electroencephalogram (EEG)-based brain-computer interface (BCI). A left/right self-paced typing exercise is analyzed ...
