Detection and interpolation of replacement noise in motion picture sequences using 3D autoregressive modelling
(IEEE, 1994)Perhaps the most common distortion in degraded film or video material is the occurrence of blotches of varying colour randomly dispersed in each frame. The blotches are caused by the abrasion of the film or collection of ... -
Detection of Illegal Dumping from CCTV at Recycling Centres
(2007)This paper describes initial work on a framework for automatic detection of illegal dumping from CCTV footage from recycle centres. Frames are seperated into foreground and background regions using a Bayesian approach that ... -
Determination of substitutional carbon content in rapid thermal chemical vapour deposited Si1-x-yGexCy on Si (1 0 0) using Raman spectroscopy
(Elsevier, 2009)The effect of carbon content on strain compensation in rapid thermal chemical vapour deposited Si1-x-yGexCy films was investigated using Raman spectroscopy as x varies from 10% to 16% and y varies from 0% to 1.8%. The ... -
Development of polar order in a bent-core liquid crystal with a new sequence of two orthogonal smectic and an adjacent nematic phase
(2011)A 4-cyanoresorcinol based bent-core liquid crystal shows a new phase sequence of two orthogonal smectic phases with short range (SmAP R) and long range (SmAP A) polar order beside a SmA-type cybotactic nematic phase (N ... -
Development of polar order in liquid crystalline phases of a banana compound with a unique sequence of three orthogonal phases
(Royal Society of Chemistry, 2010)Alkyl substituted 4-cyanoresorcinol 1,3-bisbenzoates with terephthalate based rod-like wings show a series of three orthogonal smectic phases SmA?SmAPR?SmAPA. -
Development of sodium-MRI for stroke and tumour investigations in rodents
(Springer, 2008)The aim of this research was to develop a technique for accurately detecting and quantifying the concentration of sodium in diseased tissue via MRI. Measures of tissue sodium concentration can pro- vide information ... -
Developments in Open-Source Tools for Microwave Breast Imaging
(2024)Open-source models, datasets and toolboxes are becoming increasingly common in the microwave breast imaging literature, including numericial breast models, simulated and experimental datasets and imaging and analysis ... -
Diagnosis and 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 ... -
Dielectric and electro-optic studies of a bimesogenic liquid crystal composed of bent-core and calamitic units
(2014)A bimesogen, BR1, composed of a bent-core and calamitic unit, linked laterally via a flexible spacer is investigated by dielectric and electro-optic techniques. X-ray results show the presence of clusters in the nematic ... -
Dielectric Properties of Ovine Heart at Microwave Frequencies
(2021)Accurate knowledge of the dielectric properties of biological tissues is important in dosimetry studies and for medical diagnostic, monitoring and therapeutic technologies. In particular, the dielectric properties of the ... -
Dielectric relaxation and crystallization of nanophase separated 1-propanol-isoamylbromide mixture
(2007)The effects of liquid-liquid phase separation on molecular relaxation of an apparently homogeneous mixture of 1-propanol and isoamylbromide has been studied by dielectric spectroscopy over a broad frequency and temperature ... -
Dielectric study of the electroclinic effect in the smectic-A phase
(American Physical Society, 1994)The dielectric properties of a smectic-A liquid crystal in the presence of a dc bias field are studied in the frequency range 100 Hz?1 MHz. It is shown that near the smectic-A?smectic-C* phase transition the relaxation ... -
Directional Modulation for Enhanced Privacy in Smart Watch Devices
(2023)This article studies security aspects of data transmission in on-body Internet of Things (IoT) devices through the use of Directional Modulation (DM) from a smart watch integrated antenna. DM is a beamsteering-based Physical ... -
Discontinuous change in the smectic layer thickness in ferrielectric liquid crystals
(2007)The temperature dependence of the thickness of thick free-standing films is studied using a high-resolution film thickness measurement technique. A small discontinuity in the temperature dependence of the smectic layer ... -
Discrete flexoelectric polarizations and biaxial subphases with periodicities other than 3- and 4-layers in chiral smectic liquid crystals frustrated between ferroelectricity and antiferroelectricity
(2005)The subphase for the temperature range that lies in between Sm-CA* and the three-layer Sm-CA*(1 3) subphase has been confirmed to exist using the measurements of electric-field-induced birefringence, optical rotation, and ... -
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 ... -
Dissociative CdSe/ZnS quantum dot-molecule complex for luminescent
