We investigate the use of 2 tagging technologies: Near Field Communication (NFC) and 2-dimensional barcodes. Our investigation combined a field trial and interview based study with an experimental evaluation. The field trial focused on users' experience of the usability of NFC for a range of trial services, users' perceptions of NFC use in their daily life(More)
The paper describes a simple yet highly accurate multi-layer feed-forward neural network classifier (based on the back-propagation algorithm) specifically designed to successfully distinguish between normal and abnormal higher-order statistics features of electrocardiogram (ECG) signals. The concerned abnormality in ECG is associated with ventricular late(More)

In this thesis, we investigate reliable modelling within a stochastic process algebra framework. Primarily, we consider issues of variance in stochastic process algebras as a measure of model reliability. This is in contrast to previous research in the eld which has tended to centre around mean behaviour and steady-state solutions. We present a method of(More)
In GAs applied to engineering problems (in our case, the optimisation of logic circuits) the fitness function is usually complex and the fitness evaluation is time consuming. The run time is therefore a major consideration when designing a GA for optimisation, thus a look-up table for fitness evaluation is desirable. As a consequence, it is appropriate to(More)
People who believe that their society has few impediments to upward mobility tend to oppose governmental redistribution. This is true even among the poor. Is this because people with this belief expect to be well off in the future, and hence oppose redistribution on self-interested grounds? Or is it because they believe that the less well off have not made(More)
