Objective Assessment of Perceptual Audio Quality Using ViSQOLAudio
(2017)Digital audio broadcasting services transmit substantial amounts of data that is encoded to minimize bandwidth whilst maximizing user quality of experience. Many large service providers continually alter codecs to improve ... -
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 ... -
observation of an anomalous SmA-SmC-SmA phase sequence in a bent-core liquid crystal derived from 4-cyanoresorcinol
(2020)The physical properties and the phase transitions of a smectic liquid crystal material built from achiral bent-core molecules are investigated by electro-optics, polarizing microscopy, birefringence, and spontaneous ... -
Observation of surface states within the stop-bands of a photonic crystal slab with asymmetric termination
(Oxford University Press, 2013) -
OFDM sub-carrier allocation algorithm for a multiple user data enhanced radio server (MUDERS) using a general purpose processor platform
(2004)This paper presents a novel spectrum-allocation technique designed for a high data-rate and spectrally-efficient multiple-user wireless system. The core of this system is a reconfigurable radio, implemented on a ... -
Off-line multiple object tracking using candidate selection and the viterbi algorithm
(2005)This paper presents a probabilistic framework for off-line multiple object tracking. At each timestep, a small set of deterministic candidates is generated which is guaranteed to contain the correct solution. Tracking an ... -
On missing data treatment for degraded video and film archives: a survey and a new Bayesian approach
(IEEE, 2004)Image sequence restoration has been steadily gaining in importance with the increasing prevalence of visual digital media. The demand for content increases the pressure on archives to automate their restoration activities ... -
On optimizing power allocation for reliable communication over fading channels with uninformed transmitter
(2018)We investigate energy efficient packet scheduling and power allocation problem for the services which require reliable communication to guarantee a certain quality of experience (QoE). We establish links between average ... -
On Parsing Visual Sequences with the Hidden Markov Model
(2009)Hidden Markov Models have been employed in many vision applications to model and identify events of interest. Their useis common in applications where HMMs are used to classify previously divided ... -
On Resource Reuse for Cellular Networks with Femto- and Macrocells Coexistence
(2010)This paper studies downlink resource reuse schemes for cellular networks with coexisting femtocells and macrocells. We examine two reuse schemes, termed split reuse and shared reuse. In this paper, we develop an analytical ... -
On Selfish and Altruistic Coalition Formation in Cognitive Radio Networks
(IEEE, 2010)We formulate the sensing-throughput tradeoff problem for distributed cognitive radio (CR) networks as a coalition formation game. Formation of coalitions enables the CRs to increase their achievable throughput, under the ... -
On Software Tools and Stack Architectures for Wireless Network Experiments
(2011)Simulation is still the most widely adopted perfor- mance evaluation technique in mobile ad hoc network research, in spite of a growing number of questions about the fidelity of this technique. Implementation-based ... -
On the impact of introducing advanced devices into a cognitive radio network
(IEEE, 2009)Abstract?Cognitive Radio promises better spectrum utilisation through decentralised control, sensing and decision making. The devices are intended to be inexpensive, upgradeable and adaptable. However, introducing ... -
On the internal field correction in far ]infrared absorption of highly polar molecules in neat liquids and dilute solutions
(American Institute of Physics, 1993)Far-infrared absorption spectra for liquid acetone, methylene chloride, acetonitrile, methyl iodide, and their dilute solutions in cyclohexane at 20?C are measured by molecular laser spectrometer. Measurements of dielectric ... -
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 ...
