**Subject: History of Splines**

Many years ago, during my graduate school days, I heard (or thought I

heard) that some of the earliest work on splines was done at General

Motors, and that the motivation for it was to accurately model the curved

surfaces of sheet metal that formed the shell of the car bodies. Is this

actually the case? Can someone point me to a reference that could

provide more details, and actually be used as a citation to support this

story?

**Subject: New Book, Mathematical Control Theory**

Announcing a new book:

Eduardo D. Sontag

Mathematical Control Theory: Deterministic Finite Dimensional Systems

***Second Edition***

Springer-Verlag, New York, 1998, ISBN 0-387-984895

May be ordered from 1-800-Springer toll-free in the USA, or via email from:

orders@springer-ny.com; or faxing +1.201.345.4505.

This textbook introduces the core concepts and results of Control and System

Theory. Unique in its emphasis on foundational aspects, it takes a "hybrid"

approach in which basic results are derived for discrete and continuous time

scales, and discrete and continuous state variables.

Primarily geared towards mathematically advanced undergraduate or graduate

students, it may also be suitable for a second engineering course in control

which goes beyond the classical frequency domain and state-space material.

The choice of topics, together with detailed end-of-chapter links to the

bibliography, makes it an excellent research reference as well.

The Second Edition constitutes a substantial revision and extension of the

First Edition, mainly adding or expanding upon advanced material, including:

Lie-algebraic accessibility theory, feedback linearization,

controllability of neural networks, reachability under input constraints,

topics in nonlinear feedback design (such as backstepping, damping,

control-Lyapunov functions, and topological obstructions to stabilization),

and introductions to the calculus of variations, the maximum principle,

numerical optimal control, and linear time-optimal control.

Also covered, as in the First Edition, are notions of systems and

automata theory, and the algebraic theory of linear systems, including

controllability, observability, feedback equivalence, and minimality;

stability via Lyapunov, as well as input/output methods;

linear-quadratic optimal control; observers and dynamic feedback;

Kalman filtering via deterministic optimal observation; parametrization of

stabilizing controllers, and facts about frequency domain such as the

Nyquist criterion.

**Subject: New Generation Solution Methods for PDEs**

International Conference on

``New Generation Solution Methods for PDE''

organized by

Sergei V. Nepomnyaschikh and Panayot S. Vassilevski

Organizer

The Institute of Computational Mathematics and Mathematical

Geophysics (former Computing Center) of the Siberian Devision

of Russian Academy of Sciences (SD RAS),

in cooperation with

the Central Laboratory on Parallel Processing,

Bulgarian Academy of Sciences (BAS)

will organize international conference on

``New Generation Solution Methods for PDEs''

The purpose of the conference is to bring together leading experts in

scientific computing that are actively involved in theory and computation;

that are currently developing or can develop highly efficient ``new

generation'' solution methods for PDEs. In particular, the topics of the

conference will include methods for solving PDEs and integral equations

that come from fluid flow modeling, contaminant transport, computational

electromagnetics, flow in porous media, perfectly matched layer methods

for wave problems; and generally, from engineering practice; both stationary

and time dependent, including non--linear as well as eigen--problems and

generally parameter dependent problems. Their impact on theoretical results

as well as on solving practical problems will be the main objective of the

conference.

The conference aims at generating creative new directions and ideas for

research that can be a basis for solid collaboration, especially for the

new generation of scientists. This will help towards building a community

of young scientists with balanced participation from Eastern, Western Europe

and U.S.A. to be involved in a stable cooperation in the forthcoming years,

using the experience of well known leaders of the international scientific

community.

DATE:

The workshop is scheduled for January 11--January 16, 1999 with

arrival: January 10 and departure: noon January 16, 1999.

PLACE:

Institute of Computational Mathematics and Mathematical

Geophysics, Novosibirsk, Russian Academy of Sciences

TOPICS:
