    Today's topics:

    (1) IEEE Engineering in Medicine and Biology articles
    (2) Symbolic Algebra review paper available
    (3) Epidemiological data

    (1) IEEE Engineering in Medicine and Biology articles

    Upon scanning last year's issues of IEEE EMB, the following articles I found
    rather interesting:

    Special Issue on Intelligent Systems (June 1988):

    Richard Shiavi (Vanderbilt University), Factors in Automated Gait Evaluation.
    [other articles: Knowledge-based Techniques in Instrumentation; Intelligent
    Medical Instruments; Knowledge-based Signal Processing in the Decomposition of
    Myoelectric Signals; Artificial Intelligence in Medical Consultation Systems -
    a Review; A Knowledge-based System coupled to a Mathematical Model for Inter-
    pretation of Laboratory Data].

    Special issue on Rehabilitation Engineering (September 1988):

    Roy B. Davis (Newington Children's Hospital), Clinical Gait Analysis.
    [other articles: Current Status of Rehabilitation Engineering/Technology;
    Rehabilitation Engineering: Towards a Systematic Process; Biomechanical Quan-
    tification for Assessment and Diagnosis of Dysphagia; Advances in Wheelchair
    Technology; Technological Devices for Deaf-Blind Children: Needs and Potential
    Impact; Rhythm Perception Equipment for Skin Vibratory Stimulation; Control
    Law Decoupling for 2-D Biped Walking System].

    Special Issue on Supercomputing (December 1988):

    R.T. Hart et al. (Tulane University), Supercomputer Use in Orthopaedic Bio-
    mechanics Resaearch: Focus on Functional Adaptation of Bone.
    [other articles: Perspectives in Biomedical Supercomputing; Supercomputing
    in Medical Imaging; Supercomputing Applications in Molecular Modeling; Super-
    computing in Molecular Biology: Applications to Sequence Analysis; Large Scale
    Simulations of the Hippocampus].

    (2) Symbolic Algebra

    In a CWI-Newsletter of 1988 (CWI - Centre for Mathematics and Informatics,
    Amsterdam), an interesting paper "Overview of Symbol Manipulation" was presen-
    ted by Stanley Steinberg (University of New Mexico). The paper describes cur-
    rent possibilities of symbolic algebra and a number of packages in this area
    (Macsyma, DOE Macsyma, Maple, Mathematica, Reduce, SMP, and Scratchpad II).
    The introductory paragraph is quoted here; those of you who are interested
    can obtain a LaTex source file from me by direct email (NOT via BIOMCH-L).


    The idea of using a computer to manipulate symbols has been around as
    long as the idea of using computers to manipulate numbers. Currently
    there are many areas in which computers are used to manipulate symbols;
    for example, text processing, artificial intelligence and computer
    algebra. The interest here is in programs that do symbolic
    mathematics, that is, programs that do many of the nonnumeric
    calculations from high school algebra, university calculus, ordinary
    differential equations and many other calculations usually thought of
    as being the exclusive domain of humans. The programs that perform such
    calculations are frequently called symbol manipulators. Symbol
    manipulators were certainly capable of doing interesting problems in the
    early 1960's; though used extensively, they are just now gaining general
    acceptance by the computing public. It appears that recent improvements
    in software and hardware will encourage more extensive use of the symbol
    manipulation technology. For a far more detailed discussion of symbol
    manipulation and symbol manipulators see the text by Buchberger (refer-
    ences below).

    Symbol-manipulation programs can be conveniently divided into two
    categories; special and general purpose. The interest here is
    in general purpose symbol manipulators, but it is important to realize
    that special purpose programs have played a crucial role in
    certain scientific areas. Symbol manipulators have made
    significant contributions to a wide range of problems, as a brief look
    at the conference proceedings listed below will show. The articles by
    Elvey, Ogilvie, Pavelle et. al., Steinberg, and Stoutemyer provide a
    more detailed overview of general purpose symbol manipulators than will
    be given here.

    The newest book quoted by Steinberg is "Computer Algebra: Systems and Algor-
    ithms for Algebraic Computation" by J.H. Davenport, Y. Siret & E. Tournier,
    Academic Press 1988. Applications in Biomechanics and Kinesiology are typi-
    cally in the areas of multiple-segment, inverse dynamics modelling and of
    sensitivity/error propagation analysis.


    (3) Epidemiological Data

    Following my requests earlier this month, I have not received any information
    on Epidemiology of the Motor System via email channels. Clearly, such infor-
    mation is rather scanty. Anyone having such details...?
