Although on the one hand the Web has made a large amount of information easy to access for a great number of users, on the other it does not offer any simple mechanisms to facilitate the use of a calculation application on the internet. Recently, however, Java has been developed, a new language defined by Sun whose features make it ideal for the development of network applications. In this paper we show how it is possible to use this technology to create a network computing platform for the Web sharing of applications which were not specifically devised for network use. The platform developed is also equipped with adequate security mechanisms which provide authentication services and, if required encryption. The approach proposed has been applied to porting the Sharpe tool (Symbolic Hierarchical Automated Reliability/Performance Evaluator) onto the Web.

We study a control system which includes several impulse modulators employing some kind of frequency modulation. It is shown how to chose periodic external actions in order to ensure the existence of a synchronous periodic mode, i.e. of such a mode that all the modulators emit impulses with the same frequency.

A simulation system with distributed intelligence realised by means of chaotic speed-independent integrators is considered. A fixation method for transient processes in combinational logical circuits is discussed. A chaotic integration procedure is proposed and a circuit design variant is presented for a chaotic integrator. The connection between chaotic and fuzzy integration is investigated. The method of determining the time at which the transient processes end in chaotic integrators is discussed, and the results of some experimental investigations are presented. Problems connected with the hardware realisation of functional integration elements in the simulation system for solving parabolic partial differential equations are considered. The results of a computer simulation of a system with chaotic integrators for solving this problem are presented.

This paper introduces a new concept and model for building complex ATE systems. The underlying principles were discovered over several years but were driven home by the difficulty found in modernizing a legacy test system. The result of this effort produced a solution that provided answers to the following three questions: (1) How to achieve asset interchangeability in complex test and measurement systems, (2) How to place test system software in a modular component form that can be reused in different ATE or desk top environments, and (3) How to apply new software technologies in distributedcomputing to ATE systems.

One of the major trends in computing for the 1990s is the move towards distributed systems based on a Client/Server architecture. Although a recent survey has suggested that some 41% of the major companies in the UK are either using or planning to adopt this new technology, there is little evidence at present of similar progress in the field of clinical laboratory computing. The Pathology laboratories at st. Luke's Hospital have been developing in-house computer systems using object-oriented software tools since 1988, but these were initially based on conventional file sharing and suffered from poor performance under load. The conversion to Client/Server took place in March 1993 and the results have either met or exceeded all expectations. Our experience suggests that this approach may well be the way forward for the high performance but user-friendly laboratory systems of the future.
