Spectroscopical analyis of strained silicon quantum wells
(SPIE, 2005)In this study, Strained silicon Quantum Wells (QW) were characterised using a variety of micro-scopical techniques. Among the techniques used were Transmission Electron Microscopy (TEM), Elemental Electron Loss ... -
A spectrum of colors: investigating the temporal frequency characteristics of the human visual system using a system identification approach
(IEEE, 2006)Noise input signals are commonly used in both linear and nonlinear system identification of physiological systems. This method can be applied to electrophysiological analysis of the human visual system by controlling the ... -
Spectrum without Bounds, Networks without Borders
(IEEE, 2014)The purpose of this paper is to present a vision for future mobile and wireless networks. The vision, which we call Networks without Borders (NwoB), is based on a market-place of virtual network operators which construct ... -
Speech Intelligibility prediction using a Neurogram Similarity Index Measure
(Elsevier, 2012)Discharge patterns produced by fibres from normal and impaired auditory nerves in response to speech and other complex sounds can be discriminated subjectively through visual inspection. Similarly, responses from auditory ... -
Spin-size effects in stochastic resonance in uniaxial superparamagnets
(American Physical Society, 2010)The relaxation dynamics of a uniaxial paramagnet of arbitrary spin value S, interacting with a thermal bath, are treated using the spin-boson model for a particular spin Hamiltonian consisting of the simplest uniaxial potential ... -
Spin-torque effects in thermally assisted magnetisation reversal: Method of statistical moments
(2013)Thermal fluctuations of nanomagnets driven by spin-polarized currents are treated via the Landau-Lifshitz-Gilbert equation generalized to include both the random thermal noise field and the Slonczewski spin-transfer torque ... -
Spontaneous helix formation in non-chiral bent-core liquid crystals with fast linear electro-optic effect
(2016)Liquid crystals (LCs) represent one of the foundations of modern communication and photonic technologies. Present display technologies are based mainly on nematic LCs, which suffer from limited response time for use in ... -
Spontaneous Mirror Symmetry breaking and chiral segregation in the achiral ferronematic compound DIO
(2023)An achiral compound, DIO, known to exhibit three nematic phases namely N, NX and NF, is studied by polarizing microscopy and electro-optics for different surface conditions in confinement. The high temperature N phase ... -
Spontaneous Periodic Deformations in Nonchiral Planar-Aligned Bimesogens with a Nematic-Nematic Transition and a Negative Elastic Constant
(2010)Hydrocarbon linked mesogenic dimers are found to exhibit an additional nematic phase below the conventional uniaxial nematic phase as confirmed by x-ray diffraction. The phase produces unusual periodic stripe domains in ... -
Sport Video Shot Segmentation and Classification
(SPIE, 2003)This paper considers the statistics of local appearance based measures that are suitable for the visual parsing of sport events. The moments of the colour information are computed, and the shape content in the frames is ... -
Study of Structure and Quality of Different Silicon Oxides using FTIR and Raman Microscopy
(SPIE, 2003)In this work, SiO2 and fluorine and phosphorous doped SiO2 thin films are investigated using FTIR and Raman techniques. FTIR spectroscopy was performed at normal and oblique incidence of the probe beam in transmission ... -
Superlattice structures observed in the extraordinary phase sequence and analyzed by the phenomenological Landau model and the partially molecular model.
(2013)We draw several electric-field-temperature (E-T) phase diagrams with electric-field-induced birefringence contours in the nOHFBBB1M7 (n=10) and nOTBBB1M7 (n=11) (C11) mixture system by changing the C11 concentration ... -
Surface molecular alignment by in-plane anchoring in the cell showing the. V-shaped switching
(2001)The surface molecular alignment in a sandwich cell showing V-shaped switching has been investigated using a photocontrolling method. The results indicate that the molecules on the rubbed surface are aligned parallel to ... -
Surface states in optical spectra of two-dimensional photonic crystals with various surface terminations
(2012)Reflection and transmission spectra of two-dimensional photonic crystal slabs, fabricated by photoelectrochemical etching of deep macropores and trenches in Si, are investigated theoretically and experimentally. It is ... -
Surface Tamm states in a photonic crystal slab with asymmetric termination
(2013)The reflection and transmission spectra of a finite thickness 2D Photonic Crystal Slab (PCS) based on macroporous silicon are investigated. Periodic photonic crystal region is separated from air by homogeneous silicon ... -
Surface-induced multiple re-entrant transitions
(2006)We have studied tilted surface layers in the bulk SmA temperature window of one liquid crystal using null transmission ellipsometry. Five distinct nonplanar surface structures were observed. We present analyses of the tilt ... -
Survival at the museum: A cooperation experiment with emotionally expressive virtual characters
(2018)Correctly interpreting an interlocutor's emotional expression is paramount to a successful interaction. But what happens when one of the interlocutors is a machine? The facilitation of human-machine communication and ... -
Symbol timing synchronization in software radio receivers
(2004)The Centre for Telecommunications Value Chain Driven Research (CTVR) approach to software radio is to focus on the use of a general-purpose processor (GPP). The use of a GPP to perform signal processing for communications ...
