RTM moulds are more expensive than moulds for hand laminated or pre-preg manufactured products, and therefore require more detailed consideration during product design. The variety of feasible mould designs, e.g. hand laminated, cast tooling or nickel shell tooling, complicates design for RTM. This paper describes the use of manufacturing cost estimation models for RTM moulds as a design aid. The models provide for a variety of mould designs, and for the influence of the part geometry on the manufacturing cost of both the moulds and their backing structures. The models indicate to the designer how the mould cost depends on various design parameters, which allows the designer to optimise the part and mould design for manufacturing cost.

The controller is aimed at station that forms part of a reconfigurable assembly cell. The objective of the research was to evaluate the extent to which LabVIEW facilitates reconfigurability in this context. The holons were implemented by using LabVIEW’s producer/consumer (to achieve asynchronous interand intra-holon communication) and state machine architectures. The paper discusses some implementation considerations. The paper shows that LabVIEW offers some attractive facilities for lower levels of reconfigurable control systems.

A prototype was developed that makes use of XSens MTx orientation sensors, force-sensitive resistors and an electromyogram to measure the reflex response. Suitable parameters from the sensors were identified for analysis, and clinical testing was performed on 20 subjects to collect data to evaluate the system's performance. Subjective reflex evaluations were conducted by three medical doctors according to a standard reflex grading scale using video recordings of the tests. Multi-layer feed-forward (MLFF) artificial neural networks (ANNs) were used to analyze the collected data with the aim of pattern identification and reflex grading prediction. It was found that the MLFF network delivered the corresponding reflex grading with an accuracy of 85%, which was of the same order as the rate of differences between the subjective reflex evaluations performed by the doctors (80%). The use of ANNs to analyze a reflex measurement offers a repeatable and concise representation of the reflex that is familiar to doctors and can be developed for use in a general clinical setting or for telemedicine purposes.

The two control approaches are compared for the high-level controller, implemented on a personal computer, of a modular Cartesian robot. The paper considers the properties that enhance reconfigurability and shows that the advantages of IEC 61499 are, firstly, relatively easy application when the purpose of the application is well delineated ab initio and, secondly, the modularity in the software units (the latter makes software reconfiguration easy). Agent platforms have the advantage of better development platforms. A challenge for both control approaches lies in directly interfacing with hardware since the implementations used here are Java based.
