The TIGER project is developing a set of advanced tools for real-time monitoring and diagnosis of dynamic systems with particular emphasis on gas turbine condition monitoring. The project's two applications are the most advanced gas turbine condition monitoring systems in use. These are developed by combining real-time rulebased technology with qualitative simulation and model based diagnosis.

Data mining is defined as `the process of extracting implicit information from databases, often by using various computerized analysis techniques in combination.' A number of cases demonstrating how data mining is being used within the BT Research Laboratories to discover valuable knowledge are presented. How volume data may be converted to high value information is demonstrated through a series of case studies covering a broad range of applications.

For objects viewed within images composed of an array of square pixels, the precise results of length and area measurements depend on the relative size of the objects and pixels. Each pixel is represented by its center point, lines by the sequence of four-connected pixels lying closest to the line, and areas by the pixels of which the center lie within the boundary of the figure being studied. The errors to be expected in digital measurement are discussed.

The introduction of tighter drinking water quality standards and economic considerations has focused attention on ways to improve control systems for water treatment, and for the disinfection process in particular. This control problem has, however, proved difficult to tackle with automatic control systems, due to the long contact time between the water and the disinfectant needed to ensure reliable disinfection, and hence the long delay between a control action and its measurement. The variable quality of raw water, together with the large effect that seasonal changes in ambient temperature and pH have on the dissociation, and thus the disinfecting capability, of dosed chlorine-based disinfectants, compound the problem. This paper describes a simple and cost-effective approach to the control of water chlorination that is being implemented for a large UK water treatment works.

We are interested in the monitoring and diagnosis of dynamic systems. We use implicit behavioural models supporting model based approaches. This work is driven by the needs of and applied to, two gas turbines of very different size and power. In this paper we describe how we have developed a system to provide a comprehensive fault detection and diagnosis system. The work described here is currently working continuously, on line to a gas turbine in a major chemical plant.

The convergence of techniques from the fields of mechatronics, image sensing and display, virtual reality, and broadband telecommunications has helped in the development of telepresence (TP) systems. These systems involve the combination of both real and virtual worlds to provide useful information for a variety of applications. For full telepresence, the user must have the illusion that all of their senses have been projected into the remote location. A minimum telepresence experience would therefore consist of three dimensional color vision from sensors slaved to the users head.

HIFLIRTS (High Integrity Data Communications For Light Rail Transport Systems) is a collaborative project led by ERA Technology Ltd. The project aims to advance UK's capability in the field of data communications for light rail transport applications. The on train passenger help point will provide emergency audio communication between passengers and the driver and control room, plus the ability to observe the carriage interiors from the driver's cab and the control room. To achieve this goal, compressed digital audio and video will be transmitted over networks which will be installed in future train systems.

Robot for Assisting the Integration of the Disabled (RAID) project was launched to develop a robotic workstation that will enable severely physically handicapped people to carry out various clerical and accountancy tasks without the need for human assistance. The target group of users were identified as being wheelchair users who have insufficient manipulation capability to operate a computer workstation unaided, but able to operate a two degree of freedom input device. Clinical trials have been defined by Hadar in the form of sensors, which have combinations of various tasks to simulate a typical working situation.

The development of the FOX environmental control system is described and some of the benefits of the adopted design approach are outlined. Since its launching in September of 1994, over 200 systems have been installed. Reports from users and carers about FOX have been highly complimentary. Specific benefits noted include the reliability of the system, the efficiency and kindness of technical support staff, the ease of control and training, the ability to operate at long range, the improved clarity of the communication and phone system, the provision of the family override, the new door opening feature and the comprehensive control of entertainment systems.
