In the one case we heard of, that of a Japanese University, this was as much as 170 Yen/Kb. In that case you might want to have your name removed from our distribution list.

An emphasis is placed on the new possibilities emerging in these areas because of the availability of VLSI and the potential availability of ULSI implementations. A case in point is the area of algorithms. An algorithm which is very well matched to a single-processor sequential machine may not be the best choice for the multi-processor environment that is natural in VLSI. DIGITAL SIGNAL PROCESSING: Traditional areas in digital signal processing (DSP) are supported including algorithms and theory, spectral estimation and modeling, speech processing, digital audio, and multidimensional signal processing (MDSP). Areas of emphasis include VLSI signal processing, real-time applications, and image processing and MDSP. The massive computational demands of typical MDSP applications can benefit greatly from the speed and efficiency promised by various VLSI architectures such as pipeline, systolic, wavefront, etc. ANALOG SIGNAL PROCESSING: Analog signal processing includes the development and application of linear and nonlinear filters, both in discrete and continuous time. Areas of emphasis include problems of MOS implementation, programmable analog filters and filters which combine analog and digital signal processing on the same chip. Also of interest is the emerging area of neural networks for signal processing in time and space. SIGNAL PROCESSING SYSTEMS: Signal processing systems are analog, digital, or combined analog/digital circuits and their interconnections, which implement the signal processing. The emphasis is placed on VLSI circuits and systems and their connection with signal processing both in one and multidimensions. Indeed it is the circuit or system realization of the signal processing algorithms that makes them practical. For more information, contact: Dr. John W.

(Reprinted here for information. Future issues should be requested directly.) ******************************************************************** | | | INTERNATIONAL MATRIX GROUP ( IMG ) | | -------------------------------------- | | The International Linear Algebra Community | | ------------------------------------------ | | | | E-mail Address: MAR23AA @ TECHNION (bitnet) | | | ==================================================================== 9 November 1987 ------------------------ IMG-NET Message No. 1 ------------------------ We are pleased to announce the establishment of IMG/TILAC - International Matrix Group / The International Linear Algebra Community. IMG was constituted during the Combinatorial Matrix Analysis Conference in Victoria, May 1987. The general goal of IMG is to encourage activities in linear algebra. We aim to encourage and support existing groups and individuals active in organizing meetings and publications in all aspects of linear algebra. We have no intention of supplanting or competing with existing organizations, our entire purpose is international co- ordination, to assist the developement of linear algebra. We may add new activities where and when desirable. We welcome activities in all applications of linear algebra and we desire a proper share for theoretical matrix analysis and abstract linear algebra. We plan the following: 1. IMG will initiate, encourage and co-ordinate linear algebra meetings, and support them by the means available, such as information delivery. In the long run we hope to get some financial support from various agencies. 2. IMG will edit and distribute a bulletin (named IMAGE), which will serve as a stage for discussions and opinions. It will contain essays related to linear algebra activities, as well as some information about various activities including publicity about future meetings, about new papers accepted by the linear algebra journals, about recently written theses, and about individuals (new positions, sabbaticals, leaves etc.). It may contain letters to the editor or signed columns of opinion. 3. IMG will also operate IMG-NET, an electronic news service. We will transmit announcements of IMG activities and circulate other notices of interest to linear algebraists. Membership in IMG will be open to all mathematicians interested in furthering its aims and participating in its activities. Initially there will be no cost to individuals, and we hope that costs will always be low. The group now has the following structure: Officers: Chairman - Hans Schneider Editor of IMAGE (The IMG Bulletin) - Robert C. Thompson Secretary - Daniel Hershkowitz Committee members: Richard A. Brualdi David H. Carlson Charles R. Johnson. A key feature of our strucure is an international board (IB) which consists of one representative for each of several countries in which there is linear algebra activity. There is also a representative at large. Initially the international board consists of : Belgium - P. Van Dooren Canada - P. Lancaster Czechoslovakia - M. Fiedler Germany - L. Elsner Great Britain - S. Barnett Greece - J. Maroulas Netherlands - H. Bart Hong Kong - Y. Au-Yeung Hungary - P. Rozsa Ireland - T. Laffey Israel - A. Berman Japan - T. Ando Portugal - G. de Oliveira Spain - V. Hernandez United States - G. Golub At large - B. Datta As a first step we are currently consulting members of the IB to determine what linear algebra activities are being planned in their various countries and what kind of useful support IMG can give. If you have any suggestions please communicate these to your national representative, to the representative at large, or to any of the undersigned officers. Contributions for IMAGE should be sent to Bob Thompson. If you wish to contribute an announcement to IMG-NET or be on the mailing list for IMAGE or IMG-NET, please contact Danny Hershkowitz at the address below (please send in your regular mail and e-mail addresses).
