This paper describes the development and evaluation of a custom-built impedance analyser, which uses a multiplexing bridge circuit to characterise an array of polymer-coated quartz crystal microbalance (QCM) sensors. The analyser is constructed on a single printed circuit board with minimum components and is sufficiently compact for integration into a hand-held format. The custom-built device i...

This paper describes the development of an intelligent computer-assisted language learning (ICALL) system for learning Arabic. This system could be used for learning Arabic by students at primary schools or by learners of Arabic as a second or foreign language. It explores the use of Natural Language Processing (NLP) techniques for learning Arabic. The learners are encouraged to produce sentenc...

Denotational static analysis of Java bytecode has a nice and clean compositional definition and an efficient implementation with binary decision diagrams. But it models only the functional i.e., input/output behaviour of a program P , not enough if one needs P ’s internal behaviours i.e., from the input to some internal program points. We overcome this limitation with a technique used up to now...

A computerised image analyser has been used experimentally to determine its possible usefulness in quantifying bone density. Rats were prepared for this purpose and ash weight/volume readings were obtained on femora which had been radiographed and studied to estimate radiographic density by means of the image analyser. The findings indicated that rats can be prepared by administering oestradiol...

A fully-automated open in vitro diagnostics analyser is described.
