O'Reilly, and I have recently written a manuscript on a stable "sinc" procedure of inverting the three dimensional Helmholtz equation without computing the forward solution. The three dimensional procedure can be carried out in parallel, via a sequence of one-dimensional quadratures. (We did not determine the minimum number of sources required in the manuscript, which has since been submitted for publication.) Please let me know if you are interested in receiving a LaTeX or a .ps version of this manuscript, via e-mail. --Frank Stenger e-mail: stenger@cs.utah.edu ------------------------------ From: abdelgha@lmgc.univ-montp2.fr (ABDELGHANI Maher LMGC Stucture) Subject: Modal Analysis and Identification of Mechanical Structures Date: Thu, 3 Feb 1994 Dear All, I am a Ph.D student at the University of MontpellierII, France and I am working on Modal Analysis and Identification of Mechanical Structures.

Symposium on Control Problems in Industry Holiday Inn by the Bay July 22-23, 1994 San Diego, CA This symposium will focus on industrial control applications that have benefited from recent mathematical and technological developments. The presentations have been selected primarily for the practical significance of the problems solved, though all have significant mathematical content. They are a good sample of current work in industrial control, with emphasis on real-world payoff. The speakers come from industry and academia, and they will cover a broad range of applications, including applications from the automotive, aerospace, chemical, electronics industries and applications in optics, process control and image processing. Anyone who values useful mathematics will find much of interest in this symposium. The symposium is being conducted by SIAM with the cooperation of the Institut National de Recherche en Informatique et en Automatique (INRIA). Symposium Themes: The symposium will focus on the following applications and methods: o Applications of Control Techniques in - the aerospace industry - the automotive industry - the environmental sciences - manufacturing processes - the petroleum industry o Optimal Shape Design in Aerospace Applications o Optimal Design of Micro-optics o Robust Control and H-infinity Methods Invited Presentations: There will be four 40-minute presentations in the morning and four in the afternoon of each day. In addition, a limited number of contributed presentations are expected. Control Techniques Applied to Combustion Problems.

As a first step, we have created an anonymous FTP account that contains one particular set of tools from 3DVIEWNIX. These constitute only a fraction of the entire 3DVIEWNIX system. They allow a variety of structure manipulation operations. We have included only the executables (although the actual 3DVIEWNIX distribution will include source code), both the Silicon Graphics and SUN versions, and a couple of data files. We encourage you to explore the numerous operations that are possible even with this limited set of tools. The operations are quite intuitive, but you may want to read some general instructions in the MANUAL.ps file before starting. 1. The FTP account can be accessed as follows: Hostname: mipgsun.mipg.upenn.edu (IP address: 130.91.180.111) Username: anonymous Password: your e-mail address 2. Once you are logged in, type the following command: % cd /pub 3. Set the transfer mode to 'binary' by typing the command: % binary 4. Files for SUN, SGI, and PC platforms are available on this directory. Depending on the architecture of your platform you should 'get' the appropriate one by typing the following command: % get 3dviewnix-sgi.tar.Z or % get 3dviewnix-sun4.tar.Z or % get 3dviewnix-linux_v0.99.11_SLS.v1.03.tar.Z 5. Once the file is transferred type the command: % quit 6. Now that you are back in your own machine you have to uncompress the transferred file by issuing the command: % uncompress 3dviewnix-sgi.tar.Z or % uncompress 3dviewnix-sun4.tar.Z or % uncompress 3dviewnix-linux_v0.99.11_SLS.v1.03.tar.Z 7. The next step is to 'untar' the file: % tar -xvf 3dviewnix-sgi.tar or % tar -xvf 3dviewnix-sun4.tar or % tar -xvf 3dviewnix-linux_v0.99.11_SLS.v1.03.tar Follow further instructions given in the README file. We hope you will like these tools and for information or feed-back contact us at: Vhelp@mipgsun.mipg.upenn.edu **************************************** --------- 3DVIEWNIX : A DATA-, MACHINE-, AND APPLICATION- --------- INDEPENDENT SOFTWARE SYSTEM FOR THE VISUALIZATION AND ANALYSIS OF MULTIDIMENSIONAL IMAGES 3DVIEWNIX is a transportable, very inexpensive software system developed by the Medical Image Processing Group, Department of Radiology, University of Pennsylvania, Philadelphia. It has state-of-the-art capabilities for visualizing, manipulating, and analyzing multidimensional, multimodality image information. It is designed to run on Unix machines with X-windows. It uses a data protocol that is a multidimensional generalization of the ACR-NEMA standards. We have tested it fairly well on SGI and Sun workstations. It runs also on IBM RS6000, HP 700 series and even PCs. We charge $1,000 for the software which comes with source code and manuals. You can modify it and do whatever else you want as long as it is for your own noncommercial use. For further information contact: Dr. Jayaram K.
