Articles & Papers

Below are some of the articles I wrote to express and articulate my ideas, experiments, results and or opinions. I value peer reviews of my articles and also I spend time reviewing other articles, books, etc. I spent twelve years at the University of Leeds, four of them completing my PhD in Performance Engineering and Distributed Computing (1987-1991) and nine of them as a research fellow, lecturer and then head of the networking research group (1992-2001).

During my stay at the University, I wrote (or co-authored) 38 R & D papers published in research journals and International conferences in the domains or computer networking, distributed systems and performance evaluation & engineering. Most of these resulted from research either within the University of Leeds labs or in partnership EPSRC, RoyalSociety or DTI or via collaboration with researchers from EPFL (Switzerland), Lulea (Sweden), BTExact research laboratories or Sprint Labs.

Since early 2001, I have taken positions in business and industry. I have continued writing technology reports and their impact on business but Cable&Wireless being a commercial company, these reports are commercially sensitive so I cannot make these available on this Web site. This is the difference with public funded research such as those from Universities, research councils and government institutions.

Since 1997, I also started to write about stocks, shares, investment analysis and portfolio reviews. Most of my reports are about proposing methods for stock selections, different types of portfolios, investment reviews and schemes for measuring investment performance. In 2005, I wrote an article that appeared in the Bloomberg Money magazines about collective investing. Check the Section on Investment Analysis & Portfolio Management for more details.
