Tuesday 22nd January 12th George Stephenson Lecture- Changing Trains

6.00pm Winstanley Lecture Hall, Trinity College
Presented by Tony Roche BSc FREng FIMechE

The 12th George Stephenson Lecture focuses on the progressive changes in train engineering in the UK and worldwide. The President reflects on the beneficial impact of engineering invention, innovation and development, both past and present, on train design and construction. Examples and illustrations relate to his career and also to the wider railway community. He reviews how privatisation of UK railways has influenced the demands on current operators and their suppliers. In looking forward he comments on the latest developments in High-Speed Trains in the UK and he concludes with examples from further afield of how, through innovation, future inter-city rail travel may change radically.

Tony Roche is a career rail engineer having spent some 40years with British Rail. Throughout this period he has majored on Train Engineering including being the Project Manager for the prototype High- Speed Train, Britains most successful train in the last 25 years. His career has spanned design, new construction and all levels of maintenance of locomotives and rolling stock, all against a background of management of change. He has held many senior posts within the industry, ultimately becoming the Executive Board Member of British Rail responsible for Engineering, for Safety and for Support Services. In this appointment he played a major role in the privatisation of UK Rail. He is now a Director of First Class Partnerships Limited, a small consultancy company advising senior policy and decision-makers in the rail industry. Currently the President of the Institution of Mechanical Engineers, he is also a Fellow of the Royal Academy of Engineering and a Governor of Imperial College, London.

Thursday 31st January 2002 - Filings, Filaments and FETs: Technologies for Harnessing the Waves


6.30pm Winstanley Lecture Hall, Trinity College

Prof. Steve Nightingale, Senior Technical Executive of ERA Technology Ltd

Steve is going to deliver the 'Filings Filaments and FETs' lecture he gave to the IEE three years ago. He has updated and modified the lecture a bit, basically it will be about the development in technology for radio communications over the years starting with the theoretical predictions of Maxwell and the early work of Hertz, Marconi and others on spark transmitters and coherers on to the discovery and use of the valve, the development of the transistor and then the integrated circuit. There will be demonstrations of several pieces of radio equipment ranging from a World War 1 'trench set' spark transmitter to hopefully, the latest Nokia mobile phone during this lecture together with a display of some of the technologies used within them.

Thursday 7th February 2002 - Requirements Engineering


7.15pm Winstanley Lecture Hall, Trinity College

Refreshments will be served before the talk which will begin at about 7.45pm

Prof. Kecheng Liu, Professor of Computing Science at Staffordshire University.

Kecheng, Professor of Computing Science at Staffordshire University, is a Fellow of the British Computer Society, with international recognition in information systems. He has published over 100 papers in the fields of computing. His lecture will consist of two major parts. The first part will discuss the notions of information systems from the semiotic perspective and the principles of requirements engineering. The second part illustrates the relevance of the semiotic approach to requirements engineering by looking at some examples: legacy systems re-engineering and e-business systems, followed by a summary and discussions on future issues.

Requirements engineering covers all of the activities involved in discovering, documenting and maintaining a set of requirements for a business or an IT based system. This relatively young discipline aims at delivering a set of "systematic" and "repeatable" techniques ensuring that requirements are complete, consistent and relevant. In this lecture, we shall look at the role of requirements engineering in information systems development, from a perspective of semiotics. Semiotics, the study of signs (such as icons, symbols and information) with a 300 year long history, can be applied to the development of information systems - a system that comprises people, business processes, activities and IT.


Thursday 21st February 2002 - Synthetic Aperture Radar and Sonar
6.30pm Winstanley Lecture Hall, Trinity College

Prof. Hugh Griffiths

The techniques of aperture synthesis have their origins in radioastronomy, and are now used to obtain high resolution images of the Earth's surface, from aircraft and satellites, both for remote sensing and for military surveillance purposes. More recently, similar techniques have been applied to sonar, to give high resolution images of objects on the seabed. The lecture will review the principles of synthetic aperture processing, and present a variety of examples of their application in radar and sonar

Thursday 7th March 2002 - "Airborne Surveillance Radar"
6.30pm Winstanley Lecture Hall, Trinity College

Dr. Simon Watts, Thale Sensors

Airborne radar has been an indispensable asset for surveillance operations since its first demonstration in 1937. Modern applications include maritime surveillance, detecting submarine periscopes in high sea states and classifying ships at long range; airborne early warning, detecting small aircraft at long range; and battlefield surveillance, mapping the ground at very high resolutions and detecting moving targets. The radars used to undertake these tasks are very complex, using the latest technology, and are deployed in a wide variety of airborne platforms.

This lecture will illustrate the development of airborne surveillance radars since WWII up to the present day. It will cover maritime surveillance (ASV) from H2S Mk1 (ASV Mk3), which played a vital role in hunting submarines in the Battle of the Atlantic, through to Searchwater 2000MR, which is being developed for the new RAF Nimrod MRA4 maritime reconnaissance aircraft. Surveillance of the battlefield will also be described, from the side-looking imaging radar fitted to the RAF Phantom aircraft in the 1970s through to the latest synthetic aperture radar (SAR) and ground moving target indication (GMTI) systems. Finally, air-to-air surveillance will be covered, including the Searchwater Airborne Early Warning (AEW) radars operated by the Royal Navy on their carriers.

The development of modern high-performance radars is supported by a large body of research undertaken in industry and government. Some of the airborne assets used to support such research will be described, together with an overview of some of the topics currently being studied.
