I have co-authored two technical books, both now out of print.
Smalltalk: An Introduction to Application Development Using VisualWorks
by Trevor Hopkins and Bernard Horan
A complete guide to Smalltalk-80, containing everything a user should know to start constructing applications. A very important language for those interested in object-oriented programming, one of the hot areas in software engineering.
The book provides a detailed explanation of the Smalltalk language, and describes the VisualWorks development environment and its rich library of classes.
KEY TOPICS: It includes the correct use of variables (including class instance variables); using the debugger; change management; concurrency control; the dependency mechanism; the model-view-controller paradigm; building an interactive application; using canvasses; also includes a large number of worked examples, and exercises of various degrees of complexity.
Both the specialist and the general reader will find this book accessible. It can be used by university and college students, as well as software professionals. No previous knowledge of object-oriented programming is required, but an understanding of at least one programming language (such as Pascal, C or Lisp) is necessary.
Binding: 408 pages
Publisher: Prentice Hall; 1 edition (October 23, 1995)
Language: English (Also available in German translation)
This book is now out of print, but currently still available from Amazon.
Extracts of this book have also been used as a class introduction to Smalltalk. This material can be found here.
The version of VisualWorks/Smalltalk described in this book is now long out-of-date. The up-to-date version of VisualWorks/Smalltalk can be downloaded from Cincom. I believe that most of the examples and exercises will still work; however, the "Controller" parts of the User Interface structures have been completely re-written, and any attempt to use (for example) the controlActivity() methods will not work.
Co-authored by a team of four drawn from the Departments of Computer Science and Electrical Engineering at the University of Manchester, this book is intended as an introdution to several of the software packages available commercially for the computer-aided design of electronic circuits.
A recent U.K. government initiatiave has enabled many universities, polytechnics and colleges of further education to obtain a wide variety of ECAD software packages, together with the necessary computer facilities.
This book has been compiled to meet the initial needs of both teaching staff and students who wish to begin using some of these packages. The coverage concentrates on the Silvar Lisco (SL2000) and Genrad (HILO) Simulation software together with the Silvar Lisco circuit entry and post processing products. Details are given of an interface between SPICE and the post processor PPRG.
This book is now out of print, and is no longer available (to the best of my knowledge). The content is by now completely superceded, the software products it describes are obsolete, and the book itself is probably only of historical interest.
I contributed chapter 6 (on the HILO simulator). I also typeset the entire book, using the (then) new technology of desktop publishing, using the TeX word processing software package.
Refereed papers appearing in published journals.
Centrenet: A High Performance Local Area Network,

This was the paper produced as the results of my Ph.D work on Centrenet, a Local Area Network (LAN) design based on point-to-point links and high-speed routers. Was not received well in an era of shared-media networks (Ethernet, Token Ring, etc.) but interesting to compare with modern LANs based on IP routers.

I acted as the Guest Editor for a "special issue" of the IEE/BCS Software Engineering Journal on Object-oriented Systems, (vol. 7, no. 2, March 1992). This involved selecting referees, resolving differences between these and making the final selection of papers, and writing an editorial introduction to the issue.
I have also published various book reviews and newsletter articles, not listed here.
