These appointments are in addition to the regular program and are funded jointly by the NSF and participating industries. They are designed to prepare mathematicians for research careers involving industrial interaction. Applicants should have fulfilled all requirements for a Ph.D. in Mathematics or Applied Mathematics by September 1, 1993. Familiarity with pde and/or numerical analysis is desired, but no knowledge in engineering is required. Postdoctorates* will spend 50% effort working with industrial scientists on one of the following topics: (1) Signal processing and computational ocean acoustics; (2) Diffractive optics; Maxwell equations in periodic structure; (3) Computational fluid mechanics; (4) Scattering of electromagnetic waves from complex objects; (5) Magneto-optic recording media; the writing process; (6) Semiconductors; (7) Solid state physics & computational chemical physics; (8) Problems in mathematical photography; (9) Air quality modeling; (10) Control theory; (11) Imaging analysis; (12) Micromagnetics; (13) Near-infrared imaging; (14) Applied statistical information theory and data fusion; and 50% effort in the regular IMA program. The following materials must be submitted (all material should arrive by January 15, 1993): (1) Personal statement of scientific interests, research plans, and reasons for wishing to participate in the Industrial Postdoc program. (This is an essential part of the application.) (2) Curriculum vitae and a list of publications. (3) Three letters of recommendation, to be sent directly to the IMA. *The actual hiring title will be ``Research Associate''. The University of Minnesota is an equal opportunity educator and employer. The application forms are available via anonymous ftp: ima.umn.edu or call (612) 624-6066.

The research will focus on three related areas: interactions of structures and fluids (e.g. aerodynamics), turbulence in geophysical and astrophysical environments, and computer science areas related to HPCC. Several post-doctoral positions are available immediately in Computer Science for qualified applicants. We also encourage applications for next year and from prospective HPC graduate students in Computer Science. Success- ful candidates will not necessarily have computer science backgrounds, but must have experience and interest in one or more of parallel computing (per- formance analysis, program transformation and parallelization, heterogeneous computing, fluid dynamic applications), scientific databases or visualization, and must be interested in pursuing these activities from a computer science perspective. Research will occur in a multi-disciplinary environment consist- ing of computer scientists, physical scientists and engineers. Applications and letters of recommendation should be sent to: Dr. Oliver McBryan, Dept. of Computer Science, University of Colorado, Boulder, CO 80309. mcbryan@cs.colorado.edu The University of Colorado at Boulder has a strong institutional commit- ment to the principle of diversity in all areas. In that spirit, we are par- ticularly interested in receiving applications from a broad spectrum of peo- ple, including women, members of ethnic minorities, and disabled individuals. ------------------------------ From: SIAM Date: Fri, 09 Oct 92 10:53:59 EST Subject: Contents: SIAM Matrix Analysis SIAM Journal on Matrix Analysis and Applications Volume 14, Number 1 January 1993 Contents Improved Error Bounds for Underdetermined System Solvers James W.
