This paper focuses on collaborative research activities conducted with two major UK utilities, describing the development of a web-based, Design engineering Knowledge Application System (DEKAS). This system offers automatic intelligent decision support to engineers responsible for the design and application of protection schemes associated with EHV transmission power systems. A web-based environment is promoted as the most effective medium for company-wide dissemination of the information and, knowledge captured within DEKAS. The paper also describes the integration of DEKAS with existing company data repositories in order to provide a single storage and retrieval mechanism for all pertinent information/documentation. Following the identification of 'what', 'where' and 'when' information anddata are utilised within the overall protection design process, the paper then concentrates on 'how' better use can be made of existing engineering resources, through the development of an intelligent decision support facility, utilising case-base reasoning (CBR) techniques.

Computer Assisted learning (CAL) in it's wide range of methods, successfully merges with many new fields of research. One is the field of Artificial Intelligence which strongly supports development of intelligent Computer Assisted learning (ICAL), We have developed our approach to intelligent tutoring implemented as ICAL, Approach can be described as intelligent computerized speaking tutor that supports learning based on experiments with virtual dynamic systems. Approach is suitable for learning the behavior of any dynamic system, especially in the field of complex, live, bio-medical systems. We are now implementing this approach in the field of biomedicine. Two important systems are our virtual system GLUCOMAT - homeostatic glucose regulation in human, and ECBLOG - population growth in natural eco-system.

Delivering drugs for muscle relaxation if;known to be a delicate process, which is highly nonlinear in nature. On of the most commonly-used drugs to create neurmucular blockade is atricurium. Here, we develop a dynamic neural network to model neuromuscular blockade system when atricurium is used for paralysis. The minimum-complexity neural modeling algorithm used here is based on the PAC learning theory and is shown to perform similarly on the testing and training data. The resulting model is proved to be stochastically stable and can be used as a reliable and accurate model of neuromuscular blockade system.

We report the design of a kernel-based on-line novelty detector (ADDaM - Automatic Dynamic data Mapper) and its use in the detecting of artefacts in physiological data streams gathered during general anaesthesia. ADDaM is an on-line method, that produces a robust and principled statistically partitioned history of any ordered data stream. It then constructs a probability distribution function (PDF) of the values in the stream by placing suitable Gaussian kernels at the centres of each of the partitions. The novelty of the next point entering the stream is assessed by testing against the current PDF. The more novel the point the more likely it is to be an artefact. The partitions and the PDFs are then updated after the novelty of each new point is assessed. The performance of this method is compared with artefact detection using both conventional on and off-line methods including Kalman filters, ARIMA and moving median or mean methods. The study shows that the performance of our novelty detector is as least as good as the best alternative on or off-line methods. Typical, error rates for artefact identification of 9.2% were achieved by ADDaM, compared with 16.5% for the best Kalman filtering, 9.3% for the best ARIMA model tested, 5.3% for the best moving mean method and 9.6% for the best moving median method.

This work presents a project of telemedicine applied to Intensive Care Units (ICUs). The implemented communications scheme can be adapted to patients interned in an ICU as well as to remote patients connected to the principal hospital through the communication lines. The developed system also provides maximal flexibility on the physical level allowing ISDN, ADSL, ATM and dedicated lines. This project focuses on the acquisition of medical data, the management of the communications and the visualization and posterior analysis of the data. It also includes a series of multimedia options that facilitate the collaboration during the diagnosis: use of videoconferences following video compression protocols (H.323), collaborative whiteboard (norm T.120), visualization of graphic files related to the patient, transmission of files by means of sockets, etc. The global system follows the IEEE MW P-1073 standard, which it improves by including the acquisition of analog signals and to which it adds a component of intelligent monitoring using a knowledge based system (alarm check, tendencies analysis, communications control, etc.). The system disposes oil an intelligent module (rules based system developed in OPS/R2) charged with the management of the communication between the different processes, with the data transmission priorities, the bandwidth management, the management of the charge between various resources, etc.

This paper presents a method For combining several different estimates of the mammographic skin-air interface In order to eliminate noise inherent to each individual segmentation algorithm, Given that each algorithm provides a binary mask of the breast, the first step is to isolate pixels adjacent to the skin-air interface. A final estimate of the skin-air interface for each point results from the combination of skin-air Interface location data from each procedure. data for each point is grouped as a set, upon which statistical operators, such as the elimination of outliers, are applied. Since the skin-air interface Is a continuous line, data from prior points is also used as an estimate of points that follow. Results are evaluated in terms of success with the combination of two skin-air interface segmentation algorithms. The resulting 'hybrid' technique overcomes several problems that beset each individual algorithm.
