Some of the speakers who have accepted are Margaret Cheney, Alexandre Chorin, Eric Grosse, John Hennessy, Don Knuth, Velvel Kahan, and Tinsley Oden (for a list of the organizers and updated informaton see http://www.siam.org/meetings/an97/an97home.htm). Since Stanford is at the foutainhead of Silicon Valley, there will be a number of speakers and minisymposia associated with compter science as connected with scientific computing. Speaking on behalf of the organizing committee, we are also interested in emphazing developments of applied mathematics in the Pacific rim. We invite our colleagues to organize mini-symposia which will bring to us the latest developments in your country in applied mathematics and scientific computing. Stanford is currently in the midst of a major re-building. The Computer Science Department is now housed in the Gates Building, and new buildings are being constructed for our Statistics and Electrical Engineering Departments. If you have not visited in the last five years, you'll be amazed by all the changes. We hope to see you at SIAM97. We believe it will be a meeting to remember!

The first two chapters describe scalar and vector-valued Gaussian models. Conventional autoregressive and moving-average schemes and their vector modifications are indicated. Great attention is given to the spectral models. In addition, several special methods are presented. The third chapter is dealt with non-Gaussian models. The method of nonlinear transformation of Gaussian functions is studied in some detail as well as models of random fields related to stationary point flows, models based on nonlinear stochastic differential equations, etc. The issues of compatibility of marginal distributions and covariances of random processes are considered here, too. The fourth chapter of the monograph is dealt with issues of convergence of approximate models of random fields. The last two chapters deal with stochastic modelling applications. New application areas such as simulation of meteorological processes and fields, sea surface undulation and stochastic structure of clouds are presented here. Moreover, the book includes three appendixes, in which the algorithms for modelling of random numbers, some data from the random processes theory and the connections between discrete and continuous stochastic models are discussed in brief. The book is intended for experts of statistical modelling as well as specialists of application problems of Monte Carlo methods. CONTENTS 1.

It can be found at: http://www-users.informatik.rwth-aachen.de/~roberts/meshgeneration.html I have added a software section to the page (public domain / commercial) and a directory of people working on mesh generation. In addition I have introduced a secondary index to make the page more readable. All comments and pointers on other online information are welcome.

The most effective general purpose and black-box type of preconditioners are available, including block SSOR, block tridiagonal ILU, and the block extension of point ILU with level-of-fill. Any of these ``global'' preconditioners may be coupled with one of a large collection of ``local'' preconditioners for approximately or exactly inverting or solving with the diagonal or pivot blocks. These include a number of new approximate inverse techniques. By combining a global and local preconditioner, a wide variety of preconditionings are possible, matched to the difficulty and structure of the problem. For example, the following popular methods are possible: - Block SSOR, using level-of-fill or threshold-based ILU to solve with the diagonal blocks - A block version of level-based ILU using ``exact'' inverses for the pivot blocks - ILU on a block tridiagonal system, using an approximate inverse technique suitable for the structure of the pivot blocks - Matrices with no block structure may be treated as a single block, and a single local preconditioner may be used. The blocks may be stored in dense or sparse formats, and user-defined data structures may also be used. Variable block sizes are allowed within a matrix. Operations with the blocks call the BLAS, LAPACK, or the sparse BLAS, for efficiency across many platforms. The selection of larger blocks usually gives higher performance. BPKIT supports the preconditioning of a block of vectors, to enhance efficiency when block iterative methods are used. A flexible GMRES iterative method is provided in BPKIT for users who do not have an iterative method readily available. A test program will read any linear system in Harwell-Boeing format and solve it using any combination of preconditioners and parameters specified by the user. This is important in the ``experimentation'' stage when trying to solve problems from new applications. BPKIT is callable from C/C++ and FORTRAN. BPKIT is written in standard C++ and FORTRAN, and runs on several types of workstations and Cray supercomputers. BPKIT is not parallel; for large applications it is suitable for the local solvers per processor/node or domain. The most important feature of BPKIT is that it is user extensible, since an entirely black-box approach to high-performance preconditioning is currently not possible. Local and global preconditioners written in any language may be added. A few simple lines of C++ must be written in order to make the new ``objects'' polymorphic with the others (i.e., may be treated like other local and global preconditioners). User-defined data structures for the blocks and block matrices can also be added. The source code to BPKIT is freely provided. BPKIT is available at: http://www.cs.umn.edu/~chow/bpkit.html or send mail to chow@cs.umn.edu.

Each month the site profiles the careers of mathematicians working in nonacademic positions in industry, business, or government in an effort to demonstrates the range of career opportunities available to mathematicians. These featured mathematicians then participate in an ongoing bulletin board in which they are available to answer open forum questions from users pertaining to preparation for or employment in the nonacademic sector. The Web site also contains descriptions of industry applications and links to sites with resource information for students entering the job market. The professional profiles link to companies employing mathematicians, many of which post information about job opportunities on their Web sites. There are also links to on-line job listing services that advertise positions in the sciences and engineering. Beginning in November 1996, the Web site will allow graduate students in the mathematical sciences interested in finding out more about nonacademic careers to sign up to participate in a mentoring program that will match them with a mathematician working in the nonacademic sector. Mentors can answer questions about the work environment in industry and about the process of applying for jobs outside academia. If you would like to participate in this project as a mentor or be considered as a featured mathematician, contact Linda C. Thiel, Project Director, at thiel@siam.org. Featured on the bulletin board in October are Mary Brewster, a senior research scientist with Battelle Pacific Northwest National Laboratory who does probabilistic modeling for waste tank safety analysis and develops numerical wavelet methods for problems in computational chemistry; Stewart Gleason, a consulting actuary with Ernst & Young who is building a model that will be used to price medical malpractice business for doctor groups; Jeff Kidder, a senior software engineer with Intel Corporation who is leading a project that is implementing and optimizing speech compression algorithms for use in a video conferencing system; and Craig Benham, acting chair of the Department of Biomathematical Sciences at Mount Sinai School of Medicine who works on problems related to DNA structure. ------------------------------ From: Junping Wang Date: Sat, 21 Sep 1996 19:11:57 -0500 (CDT) Subject: IMACS Symposium on Iterative Methods in Scientific Computation Due to a schedule conflict with the Annual SIAM meeting, the conference date for the "Third IMACS International Symposium on Iterative Methods in Scientific Computation" is changed to JULY 9-12, 1997.
