Following the first IUTAM Symposium held in Tokyo, in May 1992 and the second one in Paris, in November 1994, we think it should be very fruitful to gather researchers and engineers again for exchange of the newest ideas and discussion on recent developments in these areas. The following general areas will be the subject of presentations and discussions: mathematical and computational aspects of the inverse problems, parameter or system identification, shape determination, sensitivity analysis, optimization, material property characterization, ultrasonic nondestructive testing, elastodynamic inverse problems, thermal inverse problems, and other engineering applications. SYMPOSIUM LOCATION Nagano City is located at the center of Japan's main island, Honshu, and 90 minutes by bullet train from Tokyo. Nagano is surrounded by beautiful high mountains. The next Winter Olympic Games will be held in this city in February of 1998 (http://www.nagano.olympic.org/index.html). CALL FOR PAPERS Papers are invited on the topics related to a wide area of inverse problems in engineering mechanics. Contributors are requested to submit extended abstracts of no more than 2000 words in English to the Symposium Secretariat either by E-mail or by air mail (3 copies). All accepted papers will be published in the proceedings after the Symposium. DEADLINES Extended abstract (2000 words): September 1, 1997 Acceptance notification: November 15, 1997 Final Manuscript (camera-ready): March 24, 1998 Note that during the symposium only a soft-cover volume of extended abstracts will be available. The symposium book of selected papers will be published by a well-known publisher after the symposium.

Tran" Subject: Industrial Math Modeling Workshop for Graduate Students Date: Mon, 21 Apr 1997 1997 Industrial Mathematics Modeling Workshop for Graduate Students August 4-12, 1997 Center for Research in Scientific Computation North Carolina State University OBJECTIVES: * 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 FORMAT: In the Workshop the students will be divided into six teams to work on "industrial mathematics" problems brought on by experienced applied mathematicians. These problems are not academic exercises found in classrooms, but rather challenging, real-world problems from industry or applied science and require fresh, new insight for their formulation and solution. In last year Workshop, the problems were presented by scientists and researchers from Aerospace Corporation, Armstrong Lab. at Brooks AFB, Chemical Industry Institute of Toxicology, Hughes Aircraft Company, Lord Corporation and National Security Agency. The problem presenters for this year Workshop are being recruited and their names will be announced subsequently. ORGANIZERS: Fernando Reitich, North Carolina State University Jeffrey Scroggs, North Carolina State University Hien Tran, North Carolina State University APPLICATION PROCEDURE: Graduate students in mathematics, applied mathematics, numerical analysis, 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, 1997. The Workshop will cover all local living expenses and will provide partial support for travel to all U.S. citizens and permanent residents (subject to funding availability). Funding for this Workshop has been requested with the National Security Agency and the National Science Foundation.

At the previous IPNet Digest Vol.4, No.3 it was described the first part of inverse problems investigation which deals with "Uniqueness of inverse problems solution". Here is second part: "Identification errors and experimental design for inverse problems". I should like to describe the main purpose and results of this part. Other parts 3 and 4 will be describe at the following digests. Researches, conducted in first part, show an opportunity of a significant increase of experiment informatibiality. In particular it was shown that all unknown parameters of object can to determine based on only of one experiment. The execution of experiment, granting limited volume of observations sample, requires the answer to a question on organization of appropriate conditions of observation and purpose of optimum design of measurements. In this connection the main goal of second part of investigation is a method development for analysis of identification errors and finding the best points in the observation's space from the standpoint of identification errors minimum. Questions, which give attention: 2.1. How to find identification errors dependence on the position of observations for any kind of mathematical models? 2.2. Which experiment and measurement conditions guarantee a minimum level of identification errors? 2.3. How the optimum observations plan depends from the type of unknowns and functional properties of a model state? In particular, are possible to get general design in case of nonlinear dependence of input-output functions? 2.4. What is the optimum observations plan for solid heat properties determination? In particular, is there enough only one internal observation to find heat properties? It is shown that the regularization method is highly effective for solving the observational design problem in real object described by broad class of mathematical models, polynomial, ODE, PDE. Based on this method, we have proposed an approach by which to analyze comprehensively the properties of an experiment. We have use this approach to find optimal measurement point, determine the guaranteed identification error, to investigate the sensitivity and identifiability of the model, and to establish the main factors for achieving a manageable identification error. For everybody who are interested in receiving the answers on these questions please contact with me via e-mail. I should like to send the summary and papers.
