We invite you and your colleagues to submit a proposal by July 15, 1994. THE PROPOSALS SHOULD BE SENT TO THE SIAM OFFICE. The final decision on the mini-symposia will be made by the the ICIAM Program Committee to insure a balanced program. Forms for making the proposal can be obtained from SIAM (iciam@siam.org) or from the SIAM gopher. (These forms are for the genaral call for mini-symposia; ignore the dates and address of return.) We welcome suggestions for other topics and organizers. A final decision on mini-symposia will be made by Sept 15, 1994. Here is some information and helpful comments. These suggestions are guides but they are not inviolate. 1) In the interest of fairness, an individual should not participate and/or organize more than one mini-symposium. 2) The organizer should be a member of SIAM but it is desirable that the speakers be chosen to reflect the international character of the ICIAM meeting. 3) If the organizer is a speaker then he/she should nominate another person to chair the session. 4) No funding has been provided for the expenses of these mini-symposia. 5) The mini-symposium format allows for a variety of formats eg. roundtable discussions, presentations of variable length, etc. There will be a more general call for submission of mini-symposium at a later date. PLEASE PASS THIS NOTE ON TO COLLEAGUES WHO MAY NOT HAVE ACCESS TO THIS NETWORK. ------------------------------ From: Robert Skeel Date: Wed, 15 Jun 1994 11:24:29 -0500 Subject: Jack Wisdom Wins a MacArthur Fellowship Professor Jack Wisdom of MIT has been involved in a number of mammoth computational studies of the long time dynamics of the solar system, some of them on specially designed computing equipment. These have involved innovative numerical techniques including the use of special symplectic integration algorithms. Associated Press story, June 14: "For his research into the role of chaos in the stars, Wisdom was recognized Monday with a "genious grant" from the John D. and Catherine T. MacArthur Foundation. The 41-year-old physicist at the Massachusetts Institute of Technology will receive $260,000 over five years -- no strings attached. Nineteen other people received similar awards. Wisdom's reaction: "It's a complete gift from the sky." Since 1981, the MacArthur Foundation, whose founder made his fortune in insurance, has given out more than $120 million to 414 fellows. The recipients are nominated by anonymous talent scouts and chosen on the basis of skill, creativity and dedication." Official announcement: "Jack Wisdom, 41, physicist, professor, Massachusetts Institute of Technology. Significantly advanced understanding of solar system dynamics. Grant: $260,000." ------------------------------ From: Fred J. Hickernell Date: Thu, 16 Jun 1994 16:10:56 +0800 (EAT) Subject: Mathematical Software Benchmarks for Workstations We are in the process of setting up a Scientific Computing Laboratory with 1-2 servers and 15 client workstations. In assessing the performance of various models we would like to know how fast they execute numerical and statistical software, such as MATLAB. Although the developers of MATLAB and various workstation vendors have been quite helpful, we are still unable to run the MATLAB benchmarks on certain workstations under consideration (see ?? below). If anyone has done so, could they please let me know? Thanks in advance. Loops LU Sparse 3-D 2-D HP735/99 1.5 1.5 2.7 6.6 2.6 HP712/60 3.8 4.1 4.3 6.6 4.4 SUN SparcServer1000-2CPU ?? ?? ?? ?? ??

M. Ananievsky Date: Thu, 16 Jun 1994 10:32:32 +0400 Subject: Two New Books NEW BOOK: F.L.Chernousko. State Estimation for Dynamic Systems. CRC Press, Boca Raton, Florida, 1994, 304p. Researchers and engineers working in the field of applied mathematics, systems modeling, control, and identification will find this book very interesting. It is devoted to the guaranteed, or minmax, state estimation of dynamic systems which is a new and very promising branch of the mathemati- cal theory of systems and control. The book presents the state-of-the-art in this field and expounds the new effi- cient method of state estimation proposed by the author. The method makes it possible to obtain optimal two-sided ellipsoidal bounds for reachable sets of linear and non- linear control systems with discrete and continuous time, to analyze practical stability of dynamic systems subjec- ted to disturbances, to obtain two-sided estimates (fil- tering) for dynamic systems in the presence of external disturbances and observation errors. Numerical algorithms for state estimation and optimal control, as well as a number of applications and examples, are presented. The book will be useful to researcers, professors, and students in the field of applied mathematics and automatic control. NEW BOOK: Felix L. Chernousko, Nikolai N. Bolotnik, and Valeri G. Gradetsky. Manipulation Robots: Dynamics, Control, and Optimization. CRC Press, Boca Raton, Florida, 1994, 267 p. Researchers and engineers interested in recent scientific achievements in robotics will find this book very useful. The book contains basic knowledge of robotics including kinematics, dynamics, drives, control and sensor systems, etc., as well as new results obtained by the authors. The book covers challenging fields of research such as dynamics of robots with elastic parts, optimal control of manipulators, and new developments in robotics. To evaluate the elastic compliance of robots and their dynamic accuracy, the authors propose new efficient computer techniques and give numerous experimental data. Optimal control methods presented in the book allow increasing the speed and productivity of robotic opera- tions and reducing the energy consumption. New develop- ments in robotics are covered including pneumatic sensors, adaptive grippers, special robotic systems for measurement and inspection, wall-climbing robots with technological manipulators, etc. ------------------------------ From: Ronald F Boisvert Date: Fri, 17 Jun 94 16:02:03 EDT Subject: Transactions on Mathematical Software on the Web I have developed an experimental home for the ACM Transactions on Mathematical Software on the World Wide Web.

This 2-day Day was organized by Tony Chan and Gene Golub, aiming to to bring together NA groups at San Diego, LA and the Bay Area and beyond for an informal workshop, with lots of graduate student participation. As some of you know, Lake Arrowhead is a fantastic location, with pine forests, a clear blue lake, and crisp clean air. The UCLA facility has nicely furnished lodgings, conference rooms, fireplaces, and an overall rustic atmosphere. The food is not bad either. Most of us arrived at the site Monday afternoon, registered and checked in. We had two sessions that day, one before dinner, and one after, leaving time to socialize in the Lakeview room after the late session. Tuesday's events were divided into a morning and an afternoon session with a group photo-op break. The talks continued till about 3 in the afternoon. For next year's NA Day some of the sites suggested were Asilomar and Stanford. A bit earlier than June, and maybe on a weekend seemed to be the preference of most participants.

Previous conferences were held at the University of Reading in 1985 and 1992 and at the University of Oxford in 1988 in a series of conferences on the same theme held on the two sites over the last thirteen years. The aim of the conference, as in previous years, is to bring together mathematicians and engineers and other scientists in the field of computational aerodynamics and computational fluid dynamics to review recent advances in mathematical and computational techniques for modelling fluid flows. The subject area is very large with many active researchers in industry, government laboratories and universities working on a wide variety of methods and applications. The conference will cover all areas of CFD but it is hoped to emphasise three main areas: ALGORITHMS AND ALGORITHMIC NEEDS ARISING FROM APPLICATIONS NAVIER-STOKES ON FLEXIBLE GRIDS ENVIRONMENTAL CFD In addition to invited lectures the programme will include contributed talks of twenty minutes and poster sessions. These will be selected mainly on the basis of their likely contribution to the above themes. Two page abstracts for contributed papers should be submitted by 9 December 1994 stating preference for oral or poster presentation. Notification of acceptance will be given by 31 January 1995. Papers accepted for oral presentation will be required at the meeting for publication in the Proceedings.

July 18 and 19, 1994 St. Catherine's College, Oxford (scheduled to precede exactly the ISSAC 94 meeting) During the recent past, enough interest was expressed in working on a text-based standard for the inter-communication of mathematical expressions. Several groups are presently working towards this goal: OpenMath, Posso XDR, Multi, HCM proposal, etc. In December 1994, the first OpenMath workshop took place in Zurich. The meeting was considered very successful, and a second meeting was scheduled to coincide with ISSAC. During the past months, several people have made significant progress toward this goal. Arrangements are now in place for this second workshop. We are planning to arrive in Oxford on Monday (18th) morning. Although the conference rooms are reserved for all day, there are no planned activities for the morning. The meeting starts in the afternoon and continues for all of Tuesday (19th). This notice should serve a double purpose: (1) Call for papers/contributions. If you are interested in presenting a contribution at this workshop (expected contributions should be 30 minutes long), please send a title and abstract to gonnet@inf.ethz.ch. This should arrive in Zurich no later than June 30th in order to have the final program ready for the meeting. We are also expecting project updates from the groups mentioned above. (But please, let us know about them too). (2) Registration. The Institute for Scientific Computation at ETH will cover the expenses generated by the workshop (two lunches, coffee breaks, conference rooms and one night of accomodation at the residences). For this, we *must* have your registration on or before June 18th. Please send your intention to register to: Frau K.
