Subject: NIST Digital Library of Mathematical Functions Released

The NIST Digital Library if Mathematical Functions (DLMF) is
now available for free public access at
The DLMF is a richly linked online reference on the special
functions of applied mathematics, including their essential
properties, methods of computation, visualizations, pointers
to available software, and key references. A companion print
edition, the NIST Handbook of Mathematical Functions has also
been published by Cambridge University Press. See
Together these works represent a successor to the highly
successful Handbook of Mathematical Functions (M. Abramowitz
and I. Stegun, Eds.), which was published by the National Bureau
of Standards in 1964.

Subject: DUNE version 2.0 released

We are pleased to announce the release of Version 2.0 of the
``Distributed and Unified Numerics Environment'' (DUNE).

DUNE is a software framework for the numerical solution of partial
differential equations with grid-based methods. Using generic
programming techniques it strives for both: high flexibility
(efficiency of the programmer) and high performance (efficiency of the
program). DUNE provides, among other things, a large variety of local
mesh refinement techniques, a scalable parallel programming model, an
ample collection of finite element methods and efficient linear solvers.

The release includes the three core module dune-common, dune-grid, and
dune-istl; and the howtos dune-grid-howto and dune-grid-dev-howto.
Together with these five packages we released the new package
dune-localfunctions, which brings a new interface for finite element
shape functions to Dune. This package will also become a core module.
Among many smaller changes, the most notable changes are:

* The dune-grid module now features reference Elements for
arbitrary dimensions. This required a new numbering of
sub-entities. elements. This change may affect your code in
subtle ways if you depend on a particular numbering!
* A new grid implementation, the GeometryGrid, has been added. It
wraps any other DUNE grid and replaces the geometry by a generic
one. It can, for example, be used to transform a 2d Cartesian
grid into a helix.
* The GridFactory interface has been extended. It now allows file
readers to pass data associated with a given entity to the

Subject: New book, Primer on Optimal Control Theory

Announcing the April 20, 2010, publication by SIAM of:

Primer on Optimal Control Theory, by Jason L. Speyer and David H. Jacobsen

2010 / xiv + 307 pages / Hardcover / ISBN 978-0-898716-94-8 / List Price
$89.00 / SIAM Member Price $62.30 / Order Code DC20

The performance of a process – for example, how an aircraft consumes fuel –
can be enhanced when the most effective controls and operating points for
the process are determined. This holds true for many physical, economic,
biomedical, manufacturing, and engineering processes whose behavior can
often be influenced by altering certain parameters or controls to optimize
some desired property or output.

This book provides a rigorous introduction to analyzing these processes and
finding the best modes of control and operation for them. It makes optimal
control theory accessible to a large class of engineers and scientists who
are not mathematicians but have a basic mathematical background and need to
understand the sophisticated material associated with optimal control
theory. The book presents the important concepts of weak and strong control
variations leading to local necessary conditions as well as global
sufficiency of Hamilton–Jacobi–Bellman theory. It also gives the second
variation for local optimality where the associated Riccati equation is
derived from the transition matrix of the Hamiltonian system. These ideas
lead naturally to the development of H2 and H-infinity synthesis algorithms.

Subject: New book, Introduction to the Mathematics of Subdivision Surfaces

Announcing the April 20, 2010, publication by SIAM of:

Introduction to the Mathematics of Subdivision Surfaces, by Lars-Erik
Andersson and Neil F. Stewart

2010 / xxiv + 356 pages / Hardcover / ISBN 978-0-898716-97-9 / List Price
$75.00 / SIAM Member Price $52.50 / Order Code OT120

Subdivision surfaces permit a designer to specify the approximate form of a
surface defining an object and to refine and smooth the form to obtain a
more useful or attractive version of the surface.

A considerable amount of mathematical theory is required to understand the
characteristics of the resulting surfaces, and this book provides a careful
and rigorous presentation of the mathematics underlying subdivision
as used in computer graphics and animation, explaining the concepts
necessary to easily read the subdivision literature. It also organizes
subdivision methods in a unique and unambiguous hierarchy in order to
provide insight and understanding.

The material is not restricted to questions related to regularity of
subdivision surfaces at so-called extraordinary points but instead gives a
broad discussion of the various methods. It is excellent preparation for
reading more advanced texts that delve more deeply into special
questions of
regularity. The authors provide exercises and projects at the end of each
chapter. Course material, including solutions to the exercises, is
on an associated Web page.

Subject: Post-Doc. Hydrodynamics simulations for MTF based reactor

It is largely recognized by the scientific and political community that
controlled nuclear fusion is the best long-term means of meeting mankind's
growing need for a clean, renewable and inexpensive energy source. The two
main kinds of nuclear fusion devices are based on Magnetic Confinement
(MCF), like the Tokamak design, and Inertial Confinement Fusion (ICF), like
the NIF design using intense lasers. An improved understanding of plasma
physics over the last 20 years and the huge technical difficulties in
designing MCF and ICF reactors, has re-awoken the interest in several
alternative reactor designs, in particular in those that capitalize on the
increased stability of Field Reversed Configurations (FRC) with increased
currents. In this vein, General Fusion, a company from Vancouver, has
since 2002 on a project of implementing a device based on Magnetic Target
Fusion (MTF) first proposed in the 80s by researchers at the US Naval
Research Lab. This approach is an intermediate approach between MCF (low
plasma density, very strong magnetic fields, large confinement times)
and ICF
(high plasma density, very intense lasers, short confinement times).

The Post-Doc general objectives will be to numerically validate the chosen
physical models of some essential physics within General Fusion's device
thereby i) providing numerical proof-of-concept ii) reducing operating
uncertainties and iii) optimizing reactor design. Specialized numerical
often classified, exist for the simulation of specific reactor designs
(MCF or
ICF) but not for MTF. The Post-Doc will then adapt existing High-Performance
codes for Hydrodynamics, namely Frontier
[ ], in order to address
questions about plasma instabilities during compression, Lawson's criterion,
vortex collapses. Details on General Fusion's reactor can be found on

Keywords: Hydrodynamics, Bifluid Flows, FronTier, Front-Tracking,
Rayleigh-Taylor Instabilities, High Performance Computing.

Requirements: A PhD in one of the following areas is required: Applied
Mathematics, Physics, Mechanical or Electrical Engineering. Applicants
have a strong background in Scientific Computing ideally applied to Fluid

Supervision: This position will be funded by MITACS and General Fusion and
will part of a MITACS Cluster project. It will be co-supervised by Marc
Laforest (Ecole Polytechnique de Montreal), Emmanuel Lorin (Carleton

Subject: PhD position, K.U. Leuven

Numerical methods for analysis, simulation and control of linear parameter
varying systems

The analysis, simulation and control of linear systems with varying
parameters, called linear parameter-varying (LPV) systems, have become a
major research area. LPV systems naturally arise when modeling
systems (wafer stages, machine tools, cranes), chemical processes such as
liquid-gas separation, electro-hydraulic systems and active suspension
systems, automotive engines, etc. In most of these applications the
are inherently infinite-dimensional and characterized by a spatio-temporal
distribution of state variables, leading to a description by partial or
functional differential equations.

The aim of the PhD project is to develop numerical methods for the analysis
and control of linear infinite-dimensional systems with time-varying
parameters. These methods should deal with uncertainty on the system model
and must be capable of designing controllers with a prescribed structure or
order that optimize stability, robustness and performance measures. A
collaboration with the division Production Engineering, Machine Design and
Automation allows an experimental validation of the developed numerical
methods and control design tools.

Profile: The candidates must have a MSc degree in Applied Mathematics or
engineering. The selected candidate will be hosted at the Numerical
and Applied Mathematics Division, which participates in the Optimization in
Engineering Center OPTEC. He/she is expected to participate in national and
international collaborative projects in the area of scientific computing,
dynamical systems, control and optimization.
