This exciting program draws from the strengths of the various departments and colleges on campus. Associated with CAM is the Texas Institute for Computational and Applied Mathematics (TICAM). FIELDS OF GRADUATE STUDY Graduate study in Computational And Applied Mathematics embraces three component areas: applicable mathematics, numerical analysis and scientific computations, and mathematical modeling and applications chosen from an approved area in engineering or science. Graduate study opportunities are offered in numerical analysis and scientific computing, applicable mathematics, computational mechanics and physics, parallel computing and computer architecture, mathematical modeling, and in supporting areas in engineering and science which involve mathematical modeling of physical phenomena and engineering systems. FACILITIES FOR GRADUATE WORK TICAM offices and labs cover 10,000 square feet of newly renovated office space centrally located on campus. Extensive computing facilities are available for research by faculty members and graduate students in CAM, including a scientific visualization lab, a network of 18 RS6000s networked by optic fiber, and many XTERMs. Also available to researchers and graduate students are a 45 node Intel Paragon and 32 node Cray J90, administered by the UT-Austin Computation Center High Performance Computing Facility. This facility will soon acquire a medium-size massively parallel processing computer, vendor to be determined. FACULTY As part of this rapidly expanding program, several internationally renowned researchers were added to an already first class group of faculty drawn from the Colleges of Engineering and Natural Sciences. These newcomers include Ivo Babuska (formerly with the University of Maryland), Jerry Bona (formerly with Penn State), and Mary F. Wheeler (formerly with Rice University).

Madyastha Date: Mon, 30 Oct 95 02:36:17 CST Subject: Help with Matrix Algebra Proof Hi, I am a grad student in the department Electrical and Computer Engineering at Rice. In the course of my research, I came across a proposition in matrix algebra that I need to prove and I've spent 3 days on it with no success. Everyone I've asked in my department seem to be stumped too. If someone knows the proof or has seen a similar problem, could you please email me your ideas. Thank you very much. Problem: Given: R -- a symmetric positive definite matrix and P -- a diagonal matrix with entries of form exp(j*phi_m), where j = sqrt(-1) and all phi_m's aren't equal To prove: i) k^th diagonal element of inv(R + P'RP) <= (1/2)*(k^th diagonal element of inv(R)) ..... where P' denotes Hermitian transpose of P ii) And in general, to prove that k^th diagonal element of inv(R + P'RP + (P^2)'R(P^2) + ... + (P^M)'R(P^M)) <= (1/(M+1))*(k^th diagonal element of inv(R)) Thanks again for your audience.

Some of these solutions can be automatically obtained from sequential programs using compilers. However, there still exist a large class of problems, known as irregularly structured problems, that lack efficient solutions. The workshop on Parallel Algorithms for Irregularly Structured Problems - IRREGULAR 96 - is the third in the series, after Geneva and Lyon, that addresses issues related to deriving efficient solutions to irregularly structured problems. It will be held at the University of California, Santa Barbara, on August 19--21, 1996. Scope : IRREGULAR 96 aims at fostering the cooperation among practitioners and theoreticians of the field. Papers for oral presentation are solicited in all research areas related to the parallelism of irregular problems, as listed below. Topics : (non exhaustive) applications, approximating and randomized methods, automatic synthesis, branch and bound, combinatorial optimization, compiling, computer vision, load balancing, parallel data structures, scheduling and mapping, sparse matrix and symbolic computation. Publication : Proceedings are planned to be published in the Springer-Verlag Lecture Notes in Computer Science series and shall be available at the workshop. The Proccedings of IRREGULAR'95 have been published as volume 980 of Lecture Notes in Computer Science, Springer-Verlarg. Submission guidelines : To submit a contribution, send 6 copies of an extended abstract describing original research in no more than 15 pages to Yousef Saad, IRREGULAR'96 chair Computer Science Dept. University of Minnesota 4-192 EE/CSci Building 200 Union Street S.E. Minneapolis, MN 55455 USA Papers simultaneously submitted to other conferences with published proceedings will not be considered. Hard copy contributions must be in Minneapolis and e-mail (post-script file) contributions must be at irregular_submit@cs.ucsb.edu no later than March 15, 1996. A cover page should contain the author's full name, address, a 100-word abstract and keywords. If the paper is submitted electronically, the cover page in the form of an ascii-only e-mail must contain the same information. Venue : Santa Barbara is situated on the Pacific coast, ninety miles north of Los Angeles and a one-day trip from the wine country and horse ranches of neighboring Santa Ynez Valley. Santa Barbara's Spanish heritage is reflected in its architectural style, fiesta celebrations and historical landmarks, and its mild climate promotes an environment rich in outdoor activities.

This phenomenon has come to be known as ``superconvergence''. The rate of local or global convergence con be improved also by various post-processing techniques. The aim of the conference is to bring together people who work on superconvergence phenomena and a posteriori estimates in the numerical solution of differential and integral equation, variational inequa- lities and other problems of mathematical physics. The organizers intend to publish the conference proceedings. Thus, all participants are kindly asked to prepare survey papers of their own results. Articles with new superconvergence results are welcome as well. The length of any contribution should not exceed 15 pages in TEX. Scientific Committee: I. Babuska (USA), C. M. Chen (China), I.

The position is open in the framework of an ESPRIT contract in connection with European reseach centres and industrial partners. For this project we want someone with experience both in parallel computing and numerical software techniques. The heart of the activity concerns the numerical reliability of software. There exist methods for analysing models and algorithms that give an indication of the confidence to be placed in the accuracy of simulation results. The task to be completed at CERFACS consists mainly in developing a tool which employs these methods, called PRECISE, that will be used in the project for confidence testing of algorithms and applications. A prototype tool already exists so the consortium can begin testing internally early in the project. The prototype version is written for Matlab and one of the aims of this workpackage is to improve its capabilities. Some of the work will be in translating PRECISE to Fortran to allow larger (and more realistic) problems to be handled and in the production of commercial quality documentation for the tool. The position is in the Qualitative Computing Group at CERFACS, whose main research activities are - study of the stability and the reliability of numerical methods, specifically in the neighbourhood of singularities, - design of robust codes for computing some eigenelements of very large and nonnormal matrices (Arnoldi Tchebycheff method), - influence of high nonnormality on the reliability of iterative methods in linear algebra, - identification of physical applications giving birth to highly nonnormal matrices, in CFD in particular, - software tools for assessing the quality (reliability, robustness) of numerical methods. This group is part of the Parallel Algorithms Project lead by Iain Duff.
