The potential uses of smart card technology in the transport sector, with applications as diverse as access control, toll and fare payment and portable data files, are investigated. Implementations in this field are still quite small mainly due to the fact that smart cards are a relatively new technology and the lack of standards to guarantee the real inter-operability of the technology. Several proposals to compensate for these constraints have been suggested and these are briefly discussed in the paper.

The design of a case-based expert system that estimates the cost of refurbishing houses is described. The system is a new AI technique called Case-Based Reasoning (CBR). In particular, this article investigates the applicability of CBR to the estimation of refurbishment costs and shows that whilst CBR is effective, it is not entirely without pain.

Congestion is a problem in many urban areas, and traffic incidents often cause exacerbate congestion. A traffic incident could be an accidents, a broken down vehicle or a slow moving lorry. If such incidents could be detected, action could be taken quickly to stop the congestion spreading around the network. Automatic traffic controlsystems help to stop this congestion and try to optimize traffic signals to minimize delays to drivers. Although such systems work well in normal traffic flow as a network becomes congested, the ability to minimize delays is reduced. To improve this situation, three system have been developed: ASTRID, INGRID, and MONACO. These three systems are described in detail.

Gas is transported through a large network of pipes which are operated over a wide range of pressures. Within these networks are many elements which ensure that all the necessary working conditions are met. An important role is played by valves which can perform a variety of functions. A valve and actuator arrangement, which is used to throttle gas from streams found on offshore platforms, is considered. A diagnostic system which will detect and isolate specific faults is developed. British Gas supplied data of step tests from four different valves but additional data was required for the diagnostic procedure. A mathematical model of the system was derived using mathematical relationships and established laws which were interpreted in Matlab/Simulink.

Manufacturing systems Engineering courses are specifically designed to veer away from the traditional engineering approach of teaching separate engineering science subjects to a more integrated teaching approach. Robots are now being used as the integrating theme for teaching both the supporting and essential subjects. By subdividing the robot into its essential subsystems, necessary mechanical and electrical engineering principles of manufacturing systems can be adequately covered. Recognition of the subsystems enables the desired subject areas to be identified and allocated to an appropriate area for inclusion into the lecture program.

This paper is about some of the problems seen with the integration of signaling for support of Integrated Services Internet over Broadband ISDN. in it we contrast the mechanisms employed by the Internet resource reservation protocol, RSVP with those of B-ISDN and Q.2931. We do not propose any solution, but try to give an indication of the direction that signaling for broadband networks must evolve to support more effectively the higher level services that most users will be employing.

In trying to provide useful software engineering tools that utilize Computer Supported Cooperative Working it is necessary to examine the use of cognitive artefacts. This paper looks at using artefacts to support a prototype Soft systems Analysis tool based upon the work of Checkland (1981). This methodology is concerned with systems definition and relies heavily on people-people interaction. The need for a cognitive artefact arises both from the co-operative working environment and the iterative nature of the technique.

The possibility of building systems using pre-existing Commercial Off-The-Shelf (COTS) components is investigated with the growing complexity and cost involved in the development of safety critical applications, but a number of problems are posed in attempting to integrate COTS components in larger systems developments. These problems include the potential for introducing systematic errors through component mismatch and meeting the obligations of the systems safety case. These two problems and the solutions to solve these problems by using appropriate and sufficient documentation of COTS components are discussed.
