A fully abstract denotational model for higher-order processes
(IEEE Computer Society Press, 1993)A higher-order process calculus is defined in which one can describe processes which transmit as messages other processes; it may be viewed as a generalization of the lazy ?-calculus. The authors present a denotational ... -
Assigning Types to Processes
(IEEE Computer Society Press., 2000)In wide area distributed systems it is now common for higher-order code to be transferred from one domain to another; the receiving host may initialise parameters and then execute the code in its local environment. We ... -
Concurrent task performance enhances low-level visuomotor learning.
(Psychonomic Society, 2007)Visuomotor association learning involves learning to make a motor response to an arbitrary visual stimulus. This learning is essential for visual search and discrimination performance and is reliant upon a well-defined neural ... -
Towards an informal online learning community for student mental health at university
(IADIS, 2006)As a potential solution to increasing demands on mental health services at Universities this project sought to develop an informal online learning community for mental health support and education. Student?s use of the ... -

Two types of action error: electrophysiological evidence for separable inhibitory and sustained attention neural mechanisms producing error on Go/No-go tasks.
(MIT Press, 2008)Disentangling the component processes that contribute to human executive control is a key challenge for cognitive neuroscience. Here, we employ Event-Related Potentials to provide electrophysiological evidence that action ... -
Personalised ADPCM play-back devices for the handicapped
(1991)Two personalised instantaneous speech playback devices were designed and developed Both centred upon the memory efficiency advantages of Adaptive Differential Pulse Coded Modulation (ADPCM). One system is handheld and ... -
A digital signal processing index of hand tremor
(1992)An index of hand tremor is formulated from the data obtained from the analysis of the cylindrical grip strength. The tremor signal is extracted digitally from the data and the mean square power calculated. The ... -
A personal communicator of the vocally handicapped
(IEEE, 1992)An affordable personal communicator which allows full control of the voice has been designed and developed. The aid employs coded digitised speech in an efficient manner, coupled with specif- hardware in an attempt to ... -
An uncoupled oscillator model for evoked potential dynamical modelling
(IEEE, 1996)A mathematical model for evoked potentials is outlined. The model has been developed by considering phase synchronisation of the underlying neurological processes. The model, consisting of an ensemble of uncoupled ... -
Gesture recognition for augmentative human computer interaction
(IEEE, 1995)Augmentative and alternative communication has always suffered from difficulties of equipment set-up and interaction. A three-dimensional input device is presented which is based on a non-contact movement sensor. In this ... -
Assessing motility through abdominal sound monitoring
(IEEE, 1997)This paper presents the results of an investigation into a computerised system for the assessment of gastrointestinal motility through the recording and analysis of bowel sounds. The system described is aimed primarily at ... -
An uncoupled oscillator model of the Hoffmann reflex
(IEEE, 1998)A simple, new, mathematical model for the Hoffmann reflex is outlined. This model has been developed by considering phase synchronisation of the underlying neuromuscular processes by the electrical stimulation pulse. The ... -
Hybrid multiplier/CORDIC unit for online handwriting recognition
(IEEE, 1999)Traditionally online handwriting recognition (OHR) implementations use general-purpose processor architectures. The pre-processing step of OHR comprises regular array-based tasks such as normalisation, feature extraction ... -
Exaction of the optic disk boundary in digital fundus images
(IEEE, 1999)The methods of active contours (?snakes?) and level sets were applied to images of the retina in order to locate the outer boundary of the optic disk. A gradient-vector-flow based active contour was used as it performed ... -
Classification of the electrocardiogram using selected wavelet coefficients and linear discriminants
(IEEE, 2000)Twenty-live wavelet coefficients were selected as inputs and cross-validation used to estimate the classifier performance. An overall accuracy of 72.3% was achieved using a database of 500 ECG records independently classified ... -
Color video segmentation using level sets
(IEEE, 2000)A novel segmentation algorithm for color video sequences using the level set technique is proposed. This algorithm is applied to the problem of automatic face region segmentation in video sequences. Given a target color ... -
Beat classification for use in arrhythmia analysis
(IEEE, 2000)An important step in the classification of arrhythmias is beat classification. The aim of this work is to classify the beats in the MIT-BIH Arrhythmia database and to investigate pertinent features for beat classification. ...
