  • Managing intellectual property: Nail it down before you lose it

    Page(s): 266 - 267
    Save to Project icon | Click to expandQuick Abstract | PDF file iconPDF (152 KB)  

    Managing intellectual property is about using intellectual property rights (IPR) to protect an innovative concept in order to produce a commercial advantage. Intellectual property rights are the building blocks for managing intellectual property. They are a collection of registrable and unregistrable rights which have different, but sometimes overlapping, uses. IPR includes patents, registered designs, unregistered design right, copyright, database right, semiconductor design right, registered trade marks, unregistered trade marks, domain names and confidential information.

  • Some dimensions of risk not often considered by engineers

    For many years risk analysis has informed the design and operation of technologically risky systems, and many engineers and scientists consider risk to be objectively measurable. But a great deal of research into the subject by social scientists, including psychological studies into risk perception and decision-making, should interest engineers and could inform improvements to the process of risk analysis.

  • LEO and the computer revolution

    If there is a single point at which today's global IT industry was born, it could be argued that it was on the 17th November 1951, when LEO, the Lyons Electronic Office, ran the first business application on an electronic computer. 50 years later a conference was held in London to mark the '50 years of business computing'. This article is based on the 2001 Pinkerton Lecture given on the 5th November at the conference by the author, who was manager of J.C. Lyons Systems Research Unit. View full abstract»

  • Oilfield control system

    Page(s): 281 - 286

    Real-time control techniques for measuring parameters in crude oil storage tanks are described. The techniques enable the height of the oil/water layer in the storage tanks to be measured. By using this measuring technique for the oil-water interface, with the height of the interface in the tanks, coupled with the measurements of the water/oil content ratio, the density and flow rate of crude oil and the net oil quantity can be calculated. Therefore, automatic online computation of crude oil reserves and gross output quantity of net oil can be accurately predicted. The proposed method solves a difficult oil field problem that enables control of oil and gas production volumes to be maintained, particularly in low temperature environments where conventional instrumentation has proved ineffective. The control techniques enable the oil production process to function safely and reliably. View full abstract»

  • Introduction to systems engineering with use cases

    Page(s): 289 - 297
    Save to Project icon | Click to expandQuick Abstract | PDF file iconPDF (620 KB)  

    Systems engineering copes with complexity by organising development hierarchically into subsystems, some being software. Use cases are organised collections of scenarios, used to define the purposes of systems and software. They are well established in software engineering but more controversial for systems. Well organised use case models are suitable for eliciting and analysing functional requirements at all levels in a system. A companion contribution will look at non-functional requirements. Use cases increase clarity and assist with requirement reuse. View full abstract»

  • Developing a raster detector system with the J array processing language

    Page(s): 299 - 304
    Save to Project icon | Click to expandQuick Abstract | PDF file iconPDF (443 KB)  

    All digital copying aims to reproduce an original image as faithfully as possible under certain constraints. In the past, image processing had to be implemented in hardware for performance reasons. Here, a 100% software solution is outlined. In order to find such a solution an appropriate methodology based on the array processing language J is used. Although J is ideal for prototyping such designs, its wider application is seriously hindered by the lack of awareness of array processing languages amongst engineers, and by the lack of available education in this language and methodology.

  • Advanced control of a hydrogen reformer

    Page(s): 305 - 314
    Save to Project icon | Click to expandQuick Abstract | PDF file iconPDF (462 KB)  

    The objective of the hydrogen reformer process is to produce hydrogen by catalysis from desulphurised hydrocarbons. The controller to be designed is the fuel flow controller, whose main objective is to maintain the reformer at a constant temperature despite important variations in the temperature of the input steam. With the proposed controller the simulation demonstrates that the output temperature variation can be reduced to /spl plusmn/1/spl middot/2/spl deg/C, compared with /spl plusmn/1/spl middot/8/spl deg/C using the more traditional PID controller installed in the plant.

  • A distributed document management system

    Page(s): 315 - 318
    Save to Project icon | Click to expandQuick Abstract | PDF file iconPDF (267 KB)  

    A commercial system for distributed document management, which was designed during a recent TCS Programme, is described. A brief introduction to the commercial partner, AMI-The Advance Group Ltd., is given, and the design features required from the system are discussed. The article concludes by discussing the degree of commercial success accruing from the system and the associated business demands resulting from this work. View full abstract»
