The aim of this study was to identify factors other than objective sleep tendency associated with scores on the Epworth Sleepiness Scale (ESS). There were 225 subjects, of whom 40% had obstructive sleep apnoea (OSA), 16% had simple snoring, and 4.9% had snoring with sleep disruption (upper airway resistance syndrome); 9.3% had narcolepsy and 7.5% had(More)
The widely-used displacement-based finite element formulation for inviscid, compressible, small displacement fluid motions is examined, with the specific objective of calculating fluid-structure frequencies. It is shown that the formulation can be employed with confidence to predict the static response of fluids. Also the resonant frequencies of fluids in(More)
This study determined whether dexamphetamine improved symptoms and quality of life in patients with chronic fatigue syndrome. The setting was a specialized clinic within a tertiary referral hospital. This was a 6-week parallel-group, placebo-controlled trial with random allocation. There was a 2-week dose-adjustment phase and a 4-week stable treatment(More)
In this paper, we present a method for incorporating temporal smoothing (TS) into the estimate of epicardial potentials from body surface potential data. Our algorithm employs a different spatial smoothing parameter, chosen by the composite residual error and smoothing operator criteria, at each time step in the sequence. The total spatial smoothing term is(More)
Various approaches to the solution to the inverse problem of electrocardiography have been proposed over the years. Recently, the use of inverse algorithms using measured body surface Laplacians has been proposed, and in various studies this technique has been shown to outperform the traditional use of body surface potentials in certain model problems. In(More)

PHASE II REFERENCES Phase II introduces a multi-patient approach. Five virtual patients suffering from different respiratory problems: Asthma, Lung Cancer, COPD, Pneumonia and Pneumothorax have been implemented. The same narrative and Activity Model is applied for all these patients including different modes of representation. The learner is asked to make(More)
OBJECTIVE To outline recently described movement disorders during sleep which are common and poorly recognised. DATA SOURCES Computer-based literature search up to July 1990 (with the index terms sleep disorders, sleep myoclonus, nocturnal myoclonus, periodic movements in sleep, REM behaviour disorder and parasomnias) supplemented by a manual search(More)
