I am working on a method of recovering both m and x through a regularized inversion scheme. I know of two examples where such problems have been solved: 1) Pavlis & Booker(1980) solved this problem when inverting seismic arrival data to recover earthquake location(parameters) and velocity structure(continuous function) 2) deGroot-Hedlin(1991) solved this problem when inverting magnetotelluric data to recover static shift errors(parameters) and conductivity structures(continuous function) I am interested in finding references in which people have solved problems of this type, or have addressed concerns associated with solving such problems.

Miller" Subject: Submission of job opening Date: Tue, 23 Sep 1997 Post-Doctoral Research Position Available at Northeastern University in Computational Physics and Signal Processing. Description: As part of a Multidisciplinary University Research Initiative aimed at the detection, localization, and classification of buried land mines, a post-doctoral research position is available at Northeastern University in Boston, MA combining elements of computational physics and signal/image processing. The research will center around physics-based signal processing methods for solving the demining problem. The initial phase of the work will be directed toward the development of computationally efficient sensor models describing the diffusion and/or propagation of energy through the earth, the interaction of the energy with buried objects, and the process of measuring the resulting scattered fields. In particular, models for low frequency electromagnetic inductive systems and radio frequency ground penetrating radar sensors are of interest. The second portion of the research will center on the development of signal and image processing algorithms based on these models for mine detection, localization, and classification. Of interest here are statistical signal processing methods employing elements of decision and estimation theory which are robust to sensor noise and environmental clutter. Requirements: A Ph.D. and strong analytical skills in a field relevant to the above described work (eg. Electrical Engineering, Mathematics, Physics, Geoscience etc.) with experience in at least a subset of the following areas: 1. Statistical signal processing, 2. Computational electromagnetics, 3. Numerical analysis 4. Inverse scattering, 5. Multiscale methods including wavelets The candidate will be expected to carry out research in an independent manner and if interested aid in the supervision of Master's and Doctoral level graduate students. Strong oral and written English skills are a must. Funding is available for up to three years and I am looking for someone to start as soon as possible. All interested applicants are invited to contact Prof. Eric Miller 235 Forsyth Building Northeastern University Boston, MA 02115 Tel: 617-373-8386=09 Email: elmiller@ece.neu.edu Web http://www.cdsp.neu.edu/info/faculty/miller/miller.html for more information or to submit an application (CV, references, and a reprint of a published journal article). ------------------------------ From: Naoki Saito Subject: Change of address: Naoki Saito Date: Mon, 1 Sep 1997 My dear friends and colleagues, After 13+ years with Schlumberger, I decided to move on.

Naoki Saito ------------------------------ From: Lothar Reichel Subject: ETNA on CDROM Date: Sat, 13 Sep 1997 ETNA on CDROM The Electronic Transactions on Numerical Analysis (ETNA) was one of the first completely electronic scientific journals when it was launched four years ago. ETNA has the following features: * Manuscripts submitted to ETNA undergo peer review. * Mathematical Reviews reviews all articles appearing in ETNA. * Manuscripts may have color graphics. * No annual page limitations makes fast publication possible. * Key word search available. * Forward referencing. * ETNA can be accessed via the Internet by web browsers, ftp and e-mail. * First four volumes of ETNA available on CDROM. The CDROM version of ETNA can be accessed by a web browser (Mosaic). Accessing ETNA in this manner is much more convenient than accessing ETNA over the Internet when the Internet connection is slow. Many new PCs are equipped with a CDROM reader. This makes the CDROM a convenient storage medium for individuals and libraries. The first ETNA CDROM contains papers with leading-edge contributions to research in the following diverse areas of numerical analysis, analysis, linear algebra and applications: - conjugate gradient iterative methods and their variants, for solving linear systems and for obtaining eigenvalues; - general iterative methods for systems of linear equations, including parallel synchronous and asynchronous multi-splitting and inner-outer iteration methods; - singular value and QR decompositions of matrices; - applications of domain decomposition, multigrid, and finite - element methods, and their preconditioning; - Runge-Kutta methods, solutions of differential-algebraic and Riccati equations in ordinary differential equation theory; - numerical treatment of analysis problems, including Gaussian quadrature, Pade' approximations and continued fractions, and the Riemann Hypothesis. - applications of numerical analysis, e.g., in signal processing and control theory. In addition the CDROM contains a variety of public domain software programs (for Windows, Windows95, Sun Unix, SGI Unix, HP Unix, Digital Unix, and Macintosh operating systems) that will allow you to display and print the manuscripts included on the CDROM. In order to defray the cost of producing the CDROM and to cover shipping (by air mail), we are charging $25 for each CDROM. If you wish to purchase the ETNA CDROM, please send $25.00 (money order, travelers check, personal check for a U.S. bank or bank draft in U.S. dollars) to ETNA CDROM Department of Mathematics and Computer Science Kent State University Kent, OH 44242 U. S. A. For more information about ETNA and the ETNA CDROM send e-mail to etna@mcs.kent.edu or regular mail to Professor A. Ruttan, Department of Mathematics and Computer Science, Kent State University, Kent, OH 44242, USA.
