I have one reference ( Henrici and Watkins (1965), Comm. ACM, pp. 570 - 574 ) which lists a collection of test polynomials. The collection is NOT exhaustive ( I Think! ) and would like to know of any recent entries. Thank you in anticipation.

Recently, a corresponding full f90 implementation of the software has also been made available on netlib (in the ode/rksuite directory). We would be grateful to receive any and all comments on either the f77 or f90 versions of RKSUITE. As the authors, we are considering what enhancements we might include in a second release of the f77 version of RKSUITE and have recently conducted an electronic survey of users who have downloaded RKSUITE. If you haven't received the survey or have not answered the survey we would be grateful to receive any input you may have. Enhancements currently under consideration include - an interpolant for the 7(8) pair - treatment of complex dependent variables (already available in the f90 version) - inclusion of a "g-stop" facility (event location) - more examples Please forward your responses to >>> richard@nag.co.uk <<< R.

G. W. Stewart (1993) established already similar bounds for the LU, the Cholesky and the QR factorizations, but so far I read nothing about the Hessenberg factorization. Any clue is welcome!

PVM introduces distributed computing, discusses where and how to get the PVM software, provides an overview of PVM and a tutorial on setting up and running existing programs, and introduces basic programming techniques (e.g. putting PVM in existing code. There are program examples and details on how PVM works on UNIX and multiprocessor systems, advanced topics (portability, debugging, improving performance) and troubleshooting. PVM (Parallel Virtual Machine) is a software package that enables the computer user to define and allow a networked heterogeneous collection of serial, parallel, and vector computers to function as one large computer. It can be used as stand-alone software or as a foundation for other heterogeneous network software. PVM may be configured to contain various machine architectures, including sequential processors, vector processors, and multicomputers, and it can be ported to new computer architectures that may emerge.

The computer-algebra research community has made significant progress in developing applicable algorithms, particularly in the areas of ordinary and partial differential equations and systems of algebraic equations. There are now textbooks for many engineering, science and mathematics courses that use a computer algebra approach. This international conference will bring together these diverse groups for an exchange of their latest ideas. Topics included: o Solutions of ordinary and partial differential equations, including symmetry methods. o The use of symbolic techniques for numerical computations. o Applications of Grobner basis algorithms. o The use of quantifier elimination algorithms to solve problems in engineering. o The use of computer algebra in education, including precollege, college, and graduate education. o Application of computer algebra to problems in engineering and science. The conference will be run in the standard IMACS format where individuals are invited to organize a special session. Requests for proposals for special session will also be issued.

The successful candidate will be eligible for appointment to the rank of associate or full professor, and is expected to assume a term as department chair in the near future. The anticipated hiring of several new faculty members over the next five years will give the successful candidate a unique opportunity to have a strong hand in shaping the department. Applicants should have an earned doctorate or equivalent, strong administrative skills, an established record in research, and a commitment to excellence in teaching, research, and other scholarly activities. Candidates in all areas of applied mathematics will be considered. Salary will be commensurate with experience and qualifications. Harvey Mudd College is a small, highly selective, privately supported institution with major programs in physics, chemistry, engineering, mathematics, biology, and computer science. About one-third of incoming students are National Merit Scholars. The curriculum emphasizes breadth in science and engineering with a commitment to studies in the humanities and social sciences. The program is rigorous and designed to prepare students for industry as well as graduate study. Change magazine reports that HMC was the first in the country in the percentage of its alumni who earn Ph.D.s. The college has an enrollment of 630 and is associated with four other undergraduate colleges and a graduate school in Claremont, forming an academic community of about 5,000 students. Faculty at HMC may also have an appointment to the graduate school faculty and can advise doctoral students in research. HMC has 11 mathematics and five computer science faculty and the Claremont Colleges combined have a total of 48 mathematics and computer science faculty. The department has an excellent network of both office and laboratory computer workstations. Harvey Mudd College is an affirmative action, equal opportunity employer. Minority and women candidates are especially encouraged to apply. Preference will be given to applications received by December 1, 1994. Applicants should be prepared to have three letters of reference sent upon request and send a curriculum vitae, a description of their research, teaching, and administrative experience, to: Professor Robert Borrelli Search Committee Chair Department of Mathematics Harvey Mudd College Claremont, CA 91711 Lisette de Pillis Department of Mathematics Harvey Mudd College Claremont, CA 91711 (909) 621-8975 lisette_depillis@hmc.edu ------------------------------ From: Mary Reece Date: Mon, 07 Nov 1994 15:16:13 Subject: Position Available at Brunel University POSITION AVAILABLE BRUNEL UNIVERSITY BICOM, INSTITUTE OF COMPUTATIONAL MATHEMATICS RESEARCH FELLOW Up to one year, Non-UK EU Citizen FINITE ELEMENT MODELLING A Research Fellowship is immediately available for up to one year in BICOM for research into the finite element modelling of thermoforming processes for the creation of container structures from thin polymeric sheets. The work entails the extension of an existing finite element model for the thermoforming of axisymmetric structures to nonaxisymmetric structures with more complicated geometries. A dedicated SUN workstation is available for the project. The Research Fellow will need to be familiar with finite element modelling of problems in continuum mechanics. Some knowledge of solid mechanics and surface approximation, and familiarity with the SUN/UNIX environment would be an advantage. Excellent programming skills are essential. The position is financed from an EU Human Capital and Mobility Grant and is available only to non-UK EU citizens. Interested persons should, as soon as possible, contact Professor J. R.
