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 ... -
Adaptive noncontact gesture-based system for augmentative communication
(IEEE, 1999)An adaptive noncontact gesture-based system for augmentative communication is described. The system detects movement of any anatomical site through the analysis of reflected speckle. This movement is converted into ... -
A model for human skin impedance during surface functional neuromuscular stimulation
(IEEE, 1999)A new mathematical model for the bulk electrical impedance of human skin is presented. In particular this model describes the impedance of skin during surface functional neuromuscular stimulation (FNS) with square stimulation ... -
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 ... -
A parametric feature extraction and classification strategy for brain-computer interfacing
(IEEE, 2005)Parametric modeling strategies are explored in conjunction with linear discriminant analysis for use in an electroencephalogram (EEG)-based brain-computer interface (BCI). A left/right self-paced typing exercise is analyzed ... -
Visual spatial attention tracking using high-density SSVEP data for independent brain-computer communication
(2005)The steady-state visual evoked potential (SSVEP) has been employed successfully in (BCI) research, but its use in a design entirely independent of eye movement has until recently not been reported. This paper presents ... -
Visual spatial attention control in an independent brain-computer interface
(2005)This paper presents a novel brain computer interface (BCI) design employing visual evoked potential (VEP) modulations in a paradigm involving no dependency on peripheral muscles or nerves. The system utilizes ... -
Telephony-based voice pathology assessment using automated speech analysis
(IEEE, 2006)A system for remotely detecting vocal fold pathologies using telephone-quality speech is presented. The system uses a linear classifier, processing measurements of pitch perturbation, amplitude perturbation and harmonic-to-noise ... -
A patient adapting heartbeat classifier using ECG morphology and heart-beat interval features
(IEEE, 2006)An adaptive system for the automatic processing of the electrocardiogram (ECG) for the classification of heartbeats into one of the five beat classes recommended by ANSI/AAMI EC57:1998 standard is presented. The heartbeat ... -
Robust biometric person identification using automatic classifier fusion of speech, mouth, and face experts
(IEEE, 2007)Information about person identity is multimodal. Yet, most person-recognition systems limit themselves to only a single modality, such as facial appearance. With a view to exploiting the complementary nature of different ... -
Electrocardiogram based neonatal seizure detection
(IEEE, 2007)A method for the detection of seizures in the newborn using the electrocardiogram (ECG) signal is presented. Using a database of eight recordings, a method was developed for automatically annotating each 1-min epoch as ... -
Using broad phonetic group experts for improved speech recognition
(IEEE, 2007)In phoneme recognition experiments, it was found that approximately 75% of misclassified frames were assigned labels within the same broad phonetic group (BPG). While the phoneme can be described as the smallest ... -
Characterising Testing Preorders for Finite Probabilistic Processes
(2007)In 1992 Wang & Larsen extended the may- and must preorders of De Nicola and Hennessy to processes featuring probabilistic as well as nondeterministic choice. They concluded with two problems that have remained open throughout ... -
For debate... medical research output 1973-81: a romp around the United Kingdom research centres
(1984)In order to measure output of medical research in the United Kingdom, the computerised database of Excerpta Medica was used to count the number of publications emanating from each centre of research based on a medical ... -
Methane Sensing with a Novel Micromachined. Single-Frequency Fabry?Perot Laser Diode. Emitting at 1331 nm.
(1997)Spectroscopic-based gas sensing is demonstrated using micromachined single-frequency Fabry-Perot (FP) laser diodes emitting at 1.331 ?m with a side mode suppression ratio of greater than 24 dB over a significant emission ... -
A theoretical analysis of optical clock extraction using a self pulsating laser diode.
(1999)The potential for using inexpensive compact disc laser diodes as optical clock extraction elements in transparent networks has led to an increase in research into the dynamics of self-pulsating laser diodes. We use a ... -
Sampled grating DBR laser as a spectroscopic source in multigas detection at 1.52-1.57um
(2001)The first application is reported of multigas sensing using a widely tuneable sampled grating DBR laser with a tuning range 1520⩽?⩽1570 nm. The laser diode consists of four independently biased sections, two sampled ... -
Design and Construction of an Optoelectronic. Crossbar Switch Containing a Terabit per. Second Free-Space Optical Interconnect
(1999)THE COMPLETED DETAILED DESIGN AND INITIAL PHASES OF CONSTRUCTION OF AN OPTOELECTRONIC CROSSBAR DEMONSTRATOR ARE PRESENTED. THE EXPERIMENTAL SYSTEM USES HYBRID VERY LARGE SCALE INTEGRATED OPTOELECTRONICS TECHNOLOGY WHEREBY ... -
Small-signal analysis of 1.3/spl mu/m microcavity light-emitting diodes
(1999)THE MODULATION SPEED OF 1.3-MU M MICROCAVITY LIGHT-EMITTING DIODES (MCLED'S) HAS BEEN MEASURED USING A SMALL-SIGNAL MODULATION ANALYSIS, A SPEED OF 260 MHZ USING A 25-MU M DIAMETER SAMPLE AT CURRENT DENSITY OF 10 KA/CM(2) ...
