Inlier modeling for multimedia data analysis
(2004)This paper presents a robust method to estimate the unknown standard deviation of a centred normal distribution from a mixture density. This method is applied to different signal processing problems. The first one concerns ... -
Interlayer interactions and the dependence of biaxiality of the chiral smectic- C* phase on electric field in the helical unwinding process
(2007)We investigate the unwinding process of pure and racemized mixtures of 1-methylheptyloxycarbonyl phenyl-4 -carboctyloxy-biphenyl-4-carboxylate MHPOOCBC in homeotropic cells by studying i the optical texture under ... -
Interpolation formula between very low and intermediate-to-high damping Kramers escape rates for single-domain ferromagnetic particles
(American Physical Society, 2001)It is shown that the Mel?nikov-Meshkov formalism for bridging the very low damping (VLD) and intermediate-to-high damping (IHD) Kramers escape rates as a function of the dissipation parameter for mechanical particles may ... -
Intra-well relaxation process in magnetic fluids subjected to strong polarising fields
(Elsevier, 2011)We report on the frequency and field dependent complex magnetic susceptibility measurements of a kerosene-based magnetic fluid with iron oxide nanoparticles, stabilized with oleic acid, in the frequency range 0.1?6 GHz and ... -
Investigation into the Structure and Composition of Carbon/Carbon-SiC Composites
(2003)In this work, pyrolytical carbon and C-SixCy-SiC coatings were deposited by chemical vapour deposition (CVD) in a 'Cold Wall' reactor. The C/C samples from 'Schunk Kohlenstofftechnik GmbH', Germany were used as substrates. ... -
Investigation of AgInS 2/ZnS Quantum Dots by Magnetic Circular Dichroism Spectroscopy
(2019)Over recent years, quantum dots (QDs) based on ternary metal dichalcogenides have attracted a lot of attention due to their unique properties and a range of potential applications. Here, we review the latest studies on the ... -
Investigation of correlation between characteristics of Raman spectra and parameters of data-scattering obtained from phase coherence theory
(SPIE, 2005)The importance of sensitive monitoring of changes in Raman spectra in particular for microelectronic applications is discussed here. We explore the practicality of using a data-scattering method to analyse Raman spectra, ... -
Investigation of germanium implanted with hydrogen for layer transfer applications
(2011)The technology for thin Ge layer transfer by hydrogen ion-cut process is characterised in this work. Experiments were carried out to determine suitable hydrogen ion implantation doses in germanium for the low temperature ... -
Investigation of Precision Grinding Process for Production of Silicon Diaphragms
(Society of Photo-Optical Instrumentation Engineers, 2002)The application of precision grinding for the formation of a silicon diaphragm is investigated. The test structures involved 2?6 mm diam diaphragms with thicknesses in the range of 25?150 mm. When grinding is performed ... -
The investigation of the relaxation processes in antiferroelectric liquid crystals by electro-optic spectroscopy
(American Institute of Physics, 1998)Electrooptic spectroscopy of an antiferroelectric liquid crystal is carried out over a range of frequencies from 1 Hz to 100 kHz. In the antiferroelectric SmCA phase two relaxation processes are found, one at the fundamental ... -
Investigations of nano-scale helical pitch in SmCá* and SmC* phases of a chiral smectic liquid crystal using differential optical reflectivity measurements
(2006)Differential optical reflectivity (DOR) was used to study the temperature dependence of the short helical pitch in freestanding films of a liquid crystal compound. The experimentally measured DOR signal was fitted using ... -
Investigations of nanoscale helical pitch in smectic-C and smectic-C* phases of a chiral smectic liquid crystal using differential optical reflectivity measurements
(2006)Differential optical reflectivity DOR was used to study the temperature dependence of the short helical pitch in freestanding films of a liquid crystal compound. The experimentally measured DOR signal was fitted using ... -
Investigations on rare-earth doped alumino-silicate xerogel incorporated in micro-channel glass and porous silicon
(2005)Porous materials in general have received great attention from the last century. The development of new porous materials and the preparation of new composites based on porous materials is a subject of interest. The development ... -
IoT and AI-Driven Audio in the Smart City: A Rhythmanalysis inspired approach
(2018)French Philosopher and theorist Henri Lefebvre's The Production of Space (1991) has proved a crucial text for framing the discourse around contemporary urban society in the fields of human geography, critical theory, ... -
Joint Audio Visual Retrieval for Tennis Broadcasts,
(IEEE, 2003)In recent years, there has been increasing work in the area of content retrieval for sports. The idea is generally to extract important events or create summaries to allow personalisation of the media stream. While previous ... -
Joint Channel Estimation and Equalization in Massive MIMO Using a Single Pilot Subcarrier
(2023)The focus of this letter is on the reduction of the large pilot overhead in orthogonal frequency division multi-plexing (OFDM) based massive multiple-input multiple-output (MIMO) systems. We propose a novel joint channel ... -
Joint Detection, Interpolation, Motion and Parameter estimation for Image Sequences with Missing Data
(IEEE Computer Society Press, 1997)This paper presents methods for detection and reconstruction of `missing' data in image sequences which can be modelled using 3-dimensional autoregressive (3D-AR) models. The interpolation of missing data is important in ...
