D(x) and m(x) are the unknown parameter functions. s(x,t) and the flux in normal direction of u on the boundary is known for different s(x,t), in general a delta-function in space and time. An application is the optical tomography. The iterative inverse procedure is based on the repeated solution of the forward problem with known parameter functions. I am looking for a 3D solver for the diffusion equation, commercial or scientific software possibly with source code. I am interested in theoretical results about uniqueness of the parameter functions, too. Any suggestions would be appreciated. Thanks.

Workshop for Graduate Students Date: Tue, 23 Apr 1996 Dear Colleagues, I would like to invite your students to apply to the fourth Industrial Mathematics Modeling Workshop for Graduate Students, to be held here at NCSU at the end of this summer. This is an excellent opportunity for students to experience group problem-solving as applied to problems from industry and government laboratories. Below, I have included the na-digest announcement of the workshop. Additional (and more recent) information is kept at http://www4.ncsu.edu/unity/lockers/class/immworkshop/public/announce.html Please feel free to contact me for further information. I hope to hear from you (your students) soon, H.T. Tran ------------------------------------- Announcing the INDUSTRIAL MATHEMATICS MODELING WORKSHOP FOR GRADUATE STUDENTS August 5 - 13, 1996 Center for Research in Scientific Computation North Carolina State University Raleigh, North Carolina FOREWORD The Industrial Mathematics Modeling Workshop for Graduate Students, which is the fourth in the series, will take place at the Center for Research in Scientific Computation at North Carolina State University in Raleigh, North Carolina, 5-13 August 1996. This workshop is being held annually, the previous highly successful meetings was held at the Claremont College in 1993 and 1994, and at North Carolina State University last year. In line with the previous workshops the goals of this workshop are: * to expose 30 graduate students in mathematics and statistics to the challenging and exciting real-world problems from industry and government laboratories; * to introduce students to the team approach to problem solving. Funding for the workshop is provided by the National Security Agency. Additional support is anticipated from the Center for Research in Scientific Computation (CRSC) and the Department of Mathematics at NCSU. FORMAT In the workshop the students will be divided into six teams to work on "industrial mathematics" problems presented by experienced applied mathematicians. These problems are challenging, real-world problems from industry or applied science and require fresh, new insight for their formulation and solution. The problem presenters, primarily from industry and government laboratories, are being recruited and their names will be announced subsequently. We are expecting one problem presenter from the NSA. Other scientists will whom we have discussed possible participation include: scientists from Lord Corp., Micro Craft Technologies, Aerospace Corporation, Chemical Industry Institute of Toxicology, and the U.S. Air Force School of Aerospace Medicine (Brooks Air Force Base). APPLICATION PROCEDURE Graduate students in mathematics, applied mathematics, statistics or operations research can be nominated for this program by a faculty member by sending a letter of recommendation. In addition, the student is required to send in a copy of a recent transcript. THE DEADLINE FOR APPLICATION IS JUNE, 30. Students will be expected to finance their travel. The workshop will cover all local living expenses for U.S. citizens and permanent residents. ORGANIZERS Fernando Reitich (Center for Research in Scientific Computation) Jeffrey S.
