Research

My current research interests are in radionavigation, especially the development of novel digital signal processing algorithms for (previously) Decca Navigator and (currently) Loran-C. I shall be happy to supervise research students in this, or a related, area.

In the past I have also worked on:

• the implementation of programming languages, in particular Occam and Algol 68;
• parallel processing techniques;
• algorithms for text formatting;
• parsing van Wijngaarden grammars, and the applications of VWGs in natural language processing;
• formalisms for describing natural languages, especially developments of GPSG, such as G²PSG.

Some of my research papers and reports are available in PostScript form via the WWW.

Web Resources

I am an enthusiastic user of the Web for teaching and research. Here are some of my own web pages.

• I have a number of interactive web-based packages for designing various types of filter:   there's one for digital filters, another for analogue (LC) filters, and one for digital phase-locked loops.

• I am developing a web-based interactive tool for teaching circuit design & analysis, which I have used to support a first-year course in Linear Circuit Design.

• Here's a manual page and source code for my fax modem software, which makes an SGI Indy workstation behave like a fax machine or a modem.

• I have a few other software packages which are freely available for down-loading via the WWW.

• I have a page of geodesy links; if you want to find out about map projections, coordinate transformations, or how far it is from A to B, this page will tell you how (or at least where to look).

I try to use the Web wherever practicable to make tedious admin. jobs less irksome. Unfortunately, work continues to expand to fill the time available [Parkinson].

Other Interests

I have a long-standing interest in telephones.

My other interests are mainly musical: I play the oboe in, and until June 1999 I was the Secretary of, the York Symphony Orchestra, which is one of the oldest amateur orchestras in the United Kingdom. We celebrated our centenary in June 1999.
