Parametric modelling strategies and spectral analysis are explored in conjunction with Linear Discriminant Analysis to facilitate an EEG based direct-brain interface for use by disabled people. A self-paced typing exercise is analysed by employing for feature extraction, respectively, an autoregressive model, an autoregressive with exogenous input model,(More)
Z3is study investigated the automatic prediction of epochs of sleep apnea from the electrocardiogram. A large independently validated database of 70 single lead ECGs, each of approximately 8 hours in duration, was used throughout the study. Thirty five of these records were used for training and 35 retained for independent testing. Ajier considering a wide(More)
Functional magnetic resonance imaging (FMRI) is an imaging technique for determining which regions of the brain are activated in response to a stimulus or event. Early FMRI experiment paradigms were based upon those used in positron emission tomography (PET), i.e. employing a block design consisting of extended periods of 'on' against 'off' activations.(More)
The purpose of this retrospective study was to determine the diagnostic and therapeutic usefulness of gut angiography in patients with massive upper gastrointestinal bleeding from a nonvariceal source. All patients (n = 64) in this category who underwent a gut angiogram between 1980 and 1986 were studied. Pre-angiogram endoscopy was attempted in all(More)
Parametric modelling strategies are explored in conjunction with Linear Discriminant Analysis to facilitate an EEG based direct-brain interface for use by disabled people. A self-paced typing exercise is analysed by employing an autoregressive model for feature extraction and an autoregressive with exogenous input model for combined filtering and feature(More)

Deep brain stimulation (DBS) is highly effective neurosurgery for idiopathic Parkinson's disease (IPD), essential tremor (ET) and primary dystonia. DBS involves stereotactic surgical implantation of a battery-operated stimulator into deep brain nuclei. Irish patients are referred abroad for DBS and have to travel repeatedly for pre and post-operative care(More)
