New Worldwide Student Prize Award


A vital element to NAG's longevity is the fostering of young and upcoming mathematical talent. NAG was founded on academic collaboration and strong links remain with learning institutions all over the world.

In conjunction with NAG's 40th Anniversary celebrations NAG is launching the first truly global student award scheme. In the spirit of NAG's four decades of collaboration with leaders in computing, academia and industry, NAG invites departments, from institutions across the world, to apply for one of the student prizes. They will be offered for the best performances in a Masters of Science program, best projects and best numerical solutions.

Using the NAG Library to calculate financial option prices in Excel


In finance, an option is a contract that conveys the right, but not the obligation, to buy or sell a specific asset. Options are widely traded on financial markets, and so some method of determining their value (or price) is required. Several option pricing models have been developed, which have then been implemented using a range of mathematical methods; some of these implementations have been made available in the latest release of the NAG Library. We have used these routines to calculate option prices in Microsoft Excel, and present some examples (which may be downloaded from the NAG website) that illustrate the way in which NAG routines can be called from within an Excel spreadsheet.

In the news: 'Alan Turing and the ACE Computer'


A BBC news series focussing on computer pioneers continues with a story of the Ace computer, which bought together a team (Alan Turing, Jim Wilkinson, Harry Huskey and later Donald Davies) who would go on to design the technology that underpins the internet.

Jim Wilkinson was a great supporter of NAG, particularly in the early years, and was a friend and mentor to us. The NAG Fortran Library Manual still retains the original Foreword written by Jim Wilkinson and his great friend, Professor Leslie Fox.

Detonation Modelling for the Mining and Quarrying Industries: Use of the NAG Fortran Library


NAG Library user, Martin Braithwaite, Imperial College, London, has authored a paper demonstrating the user of NAG routines in detonation modelling. To read the full story visit [site:url]IndustryArticles/detonation_modelling_mining_quarry.pdf

“In many open cast mining operations, tonnes of explosives are used in individual blasts and there is a strong commercial incentive to optimize blast design. Factors in mining operations include limiting downstream processing costs associated with fines and large boulders, limiting ground vibration and associated damage, avoiding gaseous fumes from detonation products and controlling explosive and ancillary accessories (delays, detonators etc.) costs. Blast optimization can be achieved by appropriate choice of blast design (layout, explosive type and quantity, time delays on charges etc). It should be emphasized that cost of a recovery operation from a failed blast can be substantial.”


Supercomputing: Are we taking supercomputing code seriously?


Is it right that much of the supercomputing code driving scientific research and engineering design is written by people who are not software professionals, asks Andrew Jones. Someone remarked to me recently that the problem with scientific software is that most of it is written by amateurs. Harsh perhaps, but it got me thinking. The point behind the remark is that most of the software used for simulation in scientific research, especially on supercomputers, is written by scientists rather than by professional numerical software engineers. By implication, this state of affairs might be responsible for much of what some people see as the mess we are in with respect to assurance of results from the models and portable performance of the codes. The same argument might also be extended to engineering packages and data modelling.

NAG Library Contributor, Professor Ian Gladwell Retires


Ian Gladwell has been a member of the NAG community since the early 1970s. In those early days he helped Professor Joan Walsh contribute to the NAG Ordinary Differential Equations chapters of the library. When Joan retired as the formal contributor to this chapter Ian took over the responsibility.

In the mid 80's Ian took a year's sabbatical from Manchester University and worked at NAG Central Office where he acted as a direct advisor to Brian Ford in matters relating to staff, library development and implementation.

Shortly after this Professor Shampine invited Ian to join him on the staff of Southern Methodist University in Dallas, Texas.

From here Ian continued to contribute to the NAG Library and many of the ODE routines in the NAG Library today were written in this period, many jointly contributed with a NAG staff member, Dr Richard Brankin. Coincidentally Richard was also ex-Manchester.

Although now based in the USA Ian was able to advise NAG at its Technical Policy Committee meetings where he was a popular and informative participant. He was also well placed to advise our American subsidiary, NAG Inc on library matters. When the Director of NAG, Brian Ford retired, Ian flew over from the USA to deliver a talk at the meeting held in Brian's honour. His talk described the development of the NAG ODE chapter during Brian's tenure as Director.

We wish Ian a very happy retirement ' he was always a great worker and avid reader of papers. We do however expect to receive the benefits of his wisdom and counsel, delivered in his friendly Lancashire accent, for many years to come. We hope therefore that he won't suddenly (and unexpectedly) develop a passion for gardening! ' David Sayers, NAG Principal Technical Consultant.
