The purpose of the present study was to compare bruxing patterns in children with chewing and maximum intercuspal clenching as defined in a clinical and laboratory environment. Six non-bruxing controls and six children who actively bruxed according to parent reports were evaluated. Both control and experimental subjects were assessed by an initial(More)
Increasingly, applications of technology are being developed to provide care to elderly and vulnerable people living alone. This paper looks at using sensors to monitor a person's wellbeing. The paper attempts to recognise and distinguish falling, sitting and walking activities from accelerometer data. Fast Fourier Transformation (FFT) is used to extract(More)
The present study evaluated the effects of bilateral hippocampal lesions on appetitive instrumental conditioning with delayed (5-s interval) reinforcement in rats. Acquisition of a bar press response was considerably slower than rates observed with immediate reinforcement; however, no significant differences between hippocampally lesioned and control groups(More)
In this paper, we describe our experience of designing a telecare product for the elderly. This is a collaborative project involving Passivsystems Ltd and the Centre for Healthcare Modelling and Informatics at the University of Portsmouth. The research aims at adapting Passivsystems' existing in-home hub so that it is capable of providing a telecare service(More)
The disciplinary status of health informatics remains unclear. Is it an art or a science? Does it have a body of theory? A survey was devised for UK academics that teach or research health informatics. Forty-six responses were received, twenty-five from the target group (representing between a quarter and a third of the population of interest). Health(More)
This is the final report on the PAPA (Distributed Ada Debugging) project (MoD Contract number: NUW72D/1090). The project's objective was to determine the requirements of a tool to support the testing and debugging of a distributed system implemented in Ada and produce a specification for such a tool. The work was to support the SMCS project being conducted(More)
Interstitial brachytherapy for recurrent gliomas normally necessitates the invasive application of a stereotactic frame by screw-fixation which must be kept on for several hours. The use of a relocatable stereotactic frame offers many advantages over conventional systems. We present our experience in 18 patients and verify that the frame used is accurate,(More)
