An integrated development environment for the cosynthesis of hardware/software systems has been designed and implemented. The software-only applications have been partitioned into ones containing both software and hardware components. A new system architecture, based on a microcontroller, FPGA, and a single global memory shared by both the processor and the FPGA, is being tested. Initial performance measurements indicate that software-hardware speed-ups in excess of three can now be achieved.

The key to identifying and realizing true opportunities in personal communications is to first understand what people need and want, and to use this rather than technology possibilities to drive development. Second is to always stress realistic cost benefit analysis. All things considered, people and needs change very little. It is safest to assume then that they remain the same. New products must then offer real benefits and alternatives to existing products in order to compete and meet the demands of the public.

The Analytical Process control (APC) System, installed on the No.5 Electrolytic Tinplating Line (ETL) at British Steel Tinplate's Trostre Works, South Wales, is discussed. The APC System aims to provide automatic solution sampling to achieve on-line real-time analysis and closed-loop control of the process solutions used on the No.5 ETL. Consideration is being given to extending the APC System to embrace the No.4 ETL. The APC System also has the potential to be developed to allow the robot to automatically decide to override the sequence of sampling and priorities when solutions fall outside the quality control analysis range and carry out more frequent sampling of these specific solutions until they are brought back within specification.

The MATLAB and SIMULINK packages were applied to the design and analysis of a discrete-time lateral autopilot for a general tactical missile. The performance of the final design was assessed by examining the closed loop step response. Open loop margin and phase margin were used as indicators of robustness. The design achieved a settling time of at most 0.3 s with no more than 20% overshoot.

This paper describes the progress and interim findings of research at the MSI Research Institute at Loughborough University concerned with: consolidating and developing modelling methods and tools, which support the design and implementation of integrated systems. identifying requirements for modelling 'resources' to support the engineering of manufacturing enterprises. The research is funded jointly by the CDP committee of EPSRC and UK industry and is being advanced in conjunction with a consortium of manufacturing user organisations and their software and system suppliers.

Focus is placed on the proposition that regulations can be a useful source of material for building a knowledge base to support expert and technical advisor systems. The results of a research project using Prolog to code building regulations into frame-based format are described. The importance of the work includes: a step forward in dealing with issues of representation by providing a methodology for reducing regulations to computer manageable format and it highlights the significance of the constraint mechanism as the teeth of the regulation. The results may have further potential for shedding light on problems of interpretation and for documenting disputes.

Software implementation is developed in order to assist in the design of engineering structures. Such a tool will be of greatest assistance at the concept stage of structural design. On-screen diagrams, generated with the assistance of embedded expertise and readily accessed in a variety of configurations will allow the designer to make rapid evaluations and comparisons between alternative proposals, even if they are radically different in nature.

The present work focuses on the methodological issues of using Case-Based Reasoning (CBR) for unstructured domains such as Top Management Fraud (TMF), and with the evaluation of such a model. It is argued that emphasis should be given to the searching-learning loop, a prerequisite for case-based learning and reasoning systems (CBLR).

A pilot project approach where a carefully selected product development project is being used as a vehicle for good practice demonstration and learning has led to some implementation success. This article describes several alternative implementation scenarios when using the approach, as well as its implementation pitfalls. The approach is referred to as the Lucas Integrated Design & Manufacture model.

The development and evaluation of Generalised Predictive control (GPC) for on-line administration of muscle relaxant drugs in operating theatre is described. The necessary software was transferred into the operating theatre at two sites where successful trials were performed. Excellent regulation has been achieved, and the GPC algorithm displayed good robustness properties against disturbances such as surgical diathermy. The work was extended later to the multivariable case involving simultaneous control of muscle relaxation, and unconsciousness using blood pressure monitoring. While preliminary results are very encouraging, it is hoped to conduct more clinical trials using this system to establish its robustness especially over a wide spectrum of patients whose dynamics vary on a 1:4 ratio.
