Acquisition of Human EEG Data during linear Self-Motion on a Stewart Platform
(IEEE, 2009)The present study investigated the feasibility of acquiring electroencephalography (EEG) data during self-motion in human subjects. Subjects performed a visual oddball task ? designed to evoke a P3 event-related potential ... -
Brain-computer interfaces, virtual reality, and videogames
(IEEE, 2008)Major challenges must be tackled for brain-computer interfaces to mature into an established communications medium for VR applications, which will range from basic neuroscience studies to developing optimal peripherals and ... -
Extracting Separate Responses to Simultaneously Presented Continuous Auditory Stimuli: An Auditory Attention Study
(2009)Auditory Evoked Potentials (AEPs) have been used extensively in the study of auditory attention. Some weaknesses of standard AEP paradigms include (i) stimulation is discrete in nature and thus not very ecological and ... -
Serial and parallel implementations of model-based clustering via parsimonious Gaussian mixture models
(2009)Model-based clustering using a family of Gaussian mixture models, with parsimonious factor analysis like covariance structure, is described and an efficient algorithm for its implementation is presented. This algorithm ... -
Carrier-density dependence of the photoluminescence lifetimes in ZnCdSe/ZnSSe quantum wells at room temperature
(American Institute of Physics, 1999)Photoluminescence lifetimes have been measured at room temperature as a function of carrier density in ZnCdSe/ZnSSe quantum wells. We show that, at low carrier density (5 ? 109?5 ? 1010 cm ? 2), nonradiative recombination ... -
Calculated Threshold Currents of Nitride- and. Phosphide-Based Quantum-Well Lasers
(1996)No abstract available. -
Priorities in process algebras.
(IEEE Computer Society, 1988)An operational semantics for an algebraic theory of concurrency is developed that incorporates a notion of priority into the definition of the execution of actions. An equivalence based on strong observational equivalences ... -
Towards action-refinement in process algebras.
(IEEE Computer Society Press., 1989)A simple process algebra which supports a form of refinement of an action by a process is presented and the question of an appropriate equivalence relation for it is addressed. The main result is that an adequate equivalence ... -
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 ...
