We describe a variant of the Standard ML programming language which incorporates a facility for the replacement of modular components during program execution. This useful extension of the language builds upon existing compiler technology which permits the separate compilation of modular units of a Standard ML program. Deened naively, this extension would(More)
The I-Room is a virtual environment intended to support a range of collaborative activities, especially those that involve sense making, deliberation, and decision making. The I-Room case studies described in this paper all employ virtual worlds technology to provide this interaction space and show how this can be augmented with external knowledge-based and(More)
Authored by a leading name in mathematics, this engaging and clearly presented text leads the reader through the tactics involved in solving mathematical problems at the Mathematical Olympiad level. This text provides a clear, comprehensive guide to first-and second-order ordinary and partial differential equations, whilst introducing important and useful(More)
Investigation of the unipolar properties of the paced-evoked response requires special measures to eliminate the post-stimulus potential, and this in turn requires a knowledge of the properties of the electrode-tissue interface which is not supplied by any single source in the literature. We have therefore drawn together published information and some of(More)
Application domains: team and project collaboration; games development industry; whisky industry Abstract: An I-Room is an " intelligent room " which can act as a knowledge aid to support collaborative meetings and activities, especially when these involve sense-making about the current context, planning, considering options, and decision-making. The I-Room(More)
With the current interest in bipolar stimulation, there is a need for greater understanding of the electrical contributions of the two electrodes in this type of pacing. This has been investigated using a specially designed cell in which an electrode under test was immersed in a buffered saline solution (pH 7.42) at 37-38 degrees C. Four electrode types(More)
The effects of changes in stimulus interval and the infusion of isoprenaline upon myocardial depolarization and repolarization times have been determined using the unipolar ventricular evoked potential. An isolated perfused rabbit heart was the experimental vehicle and the stimulus-to-R wave (St-R) and R wave-to-end (R-E) of complex time intervals were used(More)
