Anomalous dependence of response time on the electric field in an electroclinic liquid crystal with large induced tilt and polarization
(2009)We investigate the response time of an electroclinic liquid crystal with large induced tilt and polarization (de Vries smectic A*). The response time is found to increase with the increase in electric field up to a threshold ... -
Anomalous dielectric relaxation in an N-fold cosine potential
(American Physical Society, 2003)The fractional Klein-Kramers (Fokker-Planck) equation describing the fractal time dynamics of an assembly of fixed axis dipoles rotating in an N-fold cosine potential representing the internal field due to neighboring ... -
Anomalous nonlinear dielectric and Kerr effect relaxation steady state responses in superimposed ac and dc electric fields
(American Institute of Physics, 2007)It is shown how the rotational diffusion model of polar molecules (which may be described in microscopic fashion as the diffusion limit of a discrete time random walk on the surface of the unit sphere) may be extended to ... -
Anomalous temperature dependence of layer spacing of de Vries liquid crystals: Compensation model
(2016)Smectic liquid crystals that exhibit temperature independent layer thickness offer technological advantages for their use in displays and photonic devices. The dependence of the layer spacing in SmA and SmC phases of de ... -
Antiferroelectric and ferroelectric orderings in frustrated chiral tilted smectics and a continuous change from anticlinic SmCA* to synclinic SmC*
(2010)In a frustrated binary-mixture system of ferroelectric and antiferroelectric liquid crystals, where the border line between SmCA* and SmC* in the temperature-concentration phase diagram runs almost parallel to the ordinate ... -
Antiferroelectric dielectric relaxation processes and the interlayer interaction in antiferroelectric liquid crystals
(2008)Antiphase relaxation process of antiferroelectric phase is investigated in binary mixtures of antiferroelectric and ferroelectric liquid crystalline compounds. It is found that the frequency of the antiphase mode ranges ... -
Applications and Opportunities for Cognitive Radio and Networks
(IEEE, 2012-07)we present three aspects of cognitive radio and networks of importance to the research and commercial development community. We firstly outline key emerging application areas for CR/geo-location. Secondly, we look how the ... -
Artificial Intelligence for Dynamical Systems in Wireless Communications: Modeling for the Future
(2021)Dynamical systems are no strangers in wireless communications. Our story will necessarily involve chaos, but not in the terms secure chaotic communications have introduced it: we will look for the chaos, complexity and ... -
Assessing Patient-Specific Microwave Breast Imaging in Clinical Case Studies
(2021)Microwave breast imaging has seen increasing use in clinical investigations in the past decade with over eight systems having being trialled with patients. The majority of systems use radar-based algorithms to reconstruct ... -
Attention-based audio-visual fusion for robust automatic speech recognition
(2018)Automatic speech recognition can potentially benefit from the lip motion patterns, complementing acoustic speech to improve the overall recognition performance, particularly in noise. In this paper we propose an audio-visual ... -
Automated editing of medical training video via content analysis
(SPIE, 2006)Physicians in the early part of their training inevitably undertake a course in Anatomy. Unfortunately, the amount of training medical students have with real bodies has decreased. This is further exacerbated with ... -
Automated processing of shoeprint images based on the Fourier transform for use in forensic science
(IEEE, 2005)The development of a system for automatically sorting a database of shoeprint images based on the outsole pattern in response to a reference shoeprint image is presented. The database images are sorted so that those from ... -
Automated Segmentation of Torn Frames using the Graph Cuts Technique
(2007)Film Tear is a form of degradation in archived film and is the physical ripping of the film material. Tear causes displacement of a region of the degraded frame and the loss of image data along the boundary of tear. In ... -
Automated treatment of film tear in degraded archived media
(IEEE, 2004)A common form of degradation in archived film is film tear. This is caused by the physical ripping of the film. Tear causes displacement of a region of the degraded frame and the loss of image data. As of yet no method of ... -
Automatic classification of heartbeats using ECG morphology and heartbeat interval features
(IEEE, 2004)A method for the automatic processing of the electrocardiogram (ECG) for the classification of heartbeats is presented. The method allocates manually detected heartbeats to one of the five beat classes recommended by ... -
Automatic location of IC design errors using an e-beam system
(IEEE, 1988)The ADVICE system discussed is an enhanced CAD (computer-aided design) linked E-beam tester to locate automatically design errors on custom VLSI devices. The goal is met by building a set of procedures to drive the interactive ... -
Bandwidth-adaptive waveforms for dynamic spectrum access networks
(IEEE, 2008)This paper presents a novel solution to the challenge of waveform bandwidth estimation in DySPAN systems using intentionally embedded cyclostationary signatures. Dynamic spectrum access networks (DySPANs) achieve high ... -
Bayesian example based segmentation using a hybrid energy model
(IEEE, 2007)This paper describes a supervised segmentation algorithmwhich draws inspiration from recent advances in non-parametric texture synthesis. A set of example images which have been segmented a priori are used as a guide ... -
A Bayesian Framework for Recursive Object Removal in Movie Post-Production
(IEEE, 2003)Some of the most convincing film and video effects are created in digital post-production by removing apparatus that supports or manipulates actors and objects. Wires and people, for instance, can be removed by digitally ...
