Multitudes of people are participating in global information systems by surfing the information superhighway or by simply tuning in to a global satellite TV channel. These people are said to be transported into cyberspace and can be considered as members of the information society, the society whose wealth is primarily based on information exchange rather than goods. Worldwide digital networks enable rapid communication across national boundaries and thus provide opportunities for individuals and organizations to form global partnerships and coalitions with a view to achieving their economic or political goals by changing existing political and economic power structures using high speed global information systems.

This paper is based on a project undertaken by The University of Reading with BAA plc to investigate the application of Knowledge Based Engineering to airport planning, and in addition to test the concept of adapting a proven advanced manufacturing technique to construction. It explains the background of the project drawing on examples from other industries. The goals of the project for BAA are outlined and the success and future direction of this work within the company are discussed.

The semi-formalised nature of the legal domain has encouraged work form academic lawyers and others in the development of legal knowledge-based systems. Recently, Ashley proposed the importance of building systems that assist lawyers in finding source material with which they may answer their own problems. Legal database system should make information available tailored to the particular context of the user's problem, and in doing so, would use the same relevance criteria as human experts. In CA-Clipper, two system have been developed to fulfill Ashley's criteria. The first system is called CAMLAW, and the second is ICARUS.

The role of natural language in the exploitation of an information space is discussed. The ALFRESCO Interactive System, an interactive, natural language centered system for a user interested in frescoes and paintings, was used as a specific example. The system not only provides information but also promotes other masterpieces that may attract the user. Besides understanding and using language, the system also integrates it with hypermedia both in input and output.

The coherence of any organization's operations and activities is likely to be enhanced by a clearly-defined and well-documented set of goals. Unless an organization has an effective means of defining and managing its goals, it will be unable to evaluate either the relevance of its future plans or the impact of its past and present operations. Effective goal-management is, therefore, a necessary condition for effective planning and action. The use of goal management as a framework does not, however, imply that the goals need be rigid or static. Goal management simply brings discipline and focus to the process of defining, reviewing and, when necessary, changing the goals.

As databases have become larger and more pervasive, there has been an accompanying growth in the potential and importance of knowledge discovery in databases (KDD). Knowledge discovery is the `non-trivial extraction of implicit, previously unknown and potentially useful information from data.' Such a methodology is especially applicable to large heterogeneous databases which may be distributed across different sites and managed by different database management systems (DBMS). For KDD in such large systems, architectures and data models which facilitate fast and efficient extraction and management of data are required. A fast and efficient Database Management systems (DBMS) for large, distributed heterogeneous databases is presented.

The appropriate timing of a route guidance instruction is critical to the safety and acceptability of route guidance systems. If an instruction is given too early, the driver is likely to forget the information while attending to other driver tasks. Giving the instruction too late may cause the driver to hit the brakes suddenly or maintain safe driving but miss the maneuver completely. The most obvious criteria on which to base the timing of an instruction is the distance to the junction or predicted time to the junction based on current speed. Timing should also be adjusted according to passing vehicles and the number of traffic signals passed.

A vital element of any biscuit making line is the biscuit roller, which forms the actual biscuit shape in dough prior to the baking process. The design of a biscuit molding roller is a highly skilled task, and requires a number of factors to be considered. Spooner-Vicars has been manufacturing engraved biscuit rollers for many decades, using traditional engineering practices. This paper discusses a case study within the company and relates to the application of the reconfiguration of existing manufacturing systems during the implementation of a manufacturing strategy.

This paper addresses several profound issues in meeting the efficiency and time-to-market challenges faced by hardware and software systems designers. It addresses the need for high-level techniques for structuring, parameterizing, and composing designs. It also addresses the need for incremental and flexible development and verification procedures for both hardware and software, so that users can choose the desired compromise between design quality and development time. It also addressed the need for multi-level visualization and performance assessment: an architectural model for behavioral analysis, and a system model to take into account the complexity of real devices. Current work involves integrating these models and tools into a coherent framework, and investigating their effectiveness for practical designs.

Experimental results on a laboratory micromachine illustrate how the presence of a supervisory expert system can enhance the robustness and performance of a self-tuning controller. The system provides bumpless startup of an adaptive controller, eliminating induced transient oscillations while maintaining closed-loop operation. Injection of appropriate PRBS inputs, moving parameter boundaries, etc. maintain stability of the adaptive estimator and the controller output, although instability detection algorithms ensure that if the self-tuner could fail it is switched out. The settings for a PID controller are regularly retuned, so that the back-up controller can successfully replace the self-tuning regulator, thus maintaining stable operation.
