Subject: Novel Interpolation Method

To those who are interested in "interpolation" for any dimensions (1D,
2D, 3D,......). We have good news to you.

To date, there are no existing publications regarding interpolation
methods that can be deduced analytically and extended easily to
arbitrary dimensions. In fact, there is no publication for interpolation
greater than 5-dimension. Based on the standard Monte-Carlo method as
well as the Dirac delta function, we are able to "derive" an
interpolation formulation which is good in any dimension. Please check
our site for more info and demo at:

Feedback is welcome.

Subject: GETFEM++, a C++/MATLAB package for Finite Element Methods

GETFEM++ 1.4 Available for Download with the MATLAB interface.

The GETFEM++ project is centred around the development of a
generic and efficient C++ library for elementary computations
for finite element methods. The goal is to build a library
allowing the computation of any elementary matrix (even for
mixed methods) on the largest class of methods and elements
and for arbitrary dimension (1 <= n <= 255). It offers a complete
separation between integration methods (exact or approximated),
geometric transformations (linear or not) and finite element
methods of arbitrary degrees.

Examples of available finite element methods : Pk on simplices
in arbitray degrees and dimensions, Qk on parallelepipeds,
P1, P2 with bubble functions, hierarchical elements ...

To define a new finite element method, it is sufficient to
describe it on the reference element (mainly, to define base
functions). Extensions are provided for Hermite elements,
non polynomials and vectorial elements.

Moreover, the library includes other tools for computation
with finite element such as assembly methods for classical
PDEs, interpolation methods, computation of norms, mesh
operations, boundary conditions ... This library allows to
build finite elements codes which are completely independent
of the dimension, the particular method or element. Examples
are provided.

It is possible to obtain mass matrices (or other type of
matrices) for finite element method defined on two different
meshes, allowing mortar methods or certain mixed methods.

A MATLAB interface to this library is available and fully

Subject: Special Issue of LAA on Model Reduction

Special Issue on Order Reduction of Large-Scale Systems

Order reduction is a common theme within the simulation of complex
physical processes. Such simulations often result in very large
systems. For example, large systems arise due to accuracy
requirements on the spatial discretization of fluids or structures,
in the context of lumped-circuit approximations of distributed
circuit elements, such as the interconnect or package of VLSI chips,
or in simulations of micro-electro-mechanical systems (MEMS), which
have both electrical and mechanical components. Dimension reduction is
generally required for purposes of expediency and/or storage
reduction. Applications include compressed representation, efficient
data analysis and feature extraction, real-time analysis, construction
of low-order control mechanisms, and many others. Various reduction
techniques have been devised, but many of these are described in terms
that are discipline-oriented or even application-specific even though
they share many common features and origins. This special issue is
devoted to exposing the similarities of these approaches, identifying
common features, addressing application-specific challenges, and
investigating how recent reduction methods for linear systems might
be applied to nonlinear problems.

LAA has previously published four special issues devoted to the field
of Linear Systems and Control: 1983 (vol. 50), 1989 (vols. 122-124),
1994 (vols. 203-204) and 2002 (to appear). The cross fertilization
between numerical linear algebra and linear system theory has been
very fruitful. Now, we feel it is time to broaden the scope of these
interactions. In the past decade there has been considerable activity
in the area of dimension reduction for linear dynamical control
systems. However, dimension reduction has a much broader range of
application and interpretation. The goals of this special issue are
to highlight leading approaches and remaining problems in model
reduction for linear system theory, emphasize connections to POD,
extend theory and methodology to nonlinear problems, address
application-specific techniques.

This special issue will be open to all papers with significant new
results in dimension reduction of large systems where either linear
algebraic methods play an important role or new tools and problems of
linear algebraic nature are presented. Survey papers that illustrate
common themes across disciplines and application areas, and especially
where Linear Algebra techniques play a central role are highly
encouraged. Papers must meet the publication standards of Linear
Algebra and Its Applications and will be refereed in the usual way.

Areas and topics of interest for this special issue include, but are not
limited to:

* Methods and Theory for

- Linear (time-invariant and time-varying) dynamical systems
- Descriptor (singular) systems
- Nonlinear dynamical systems
- Second-order systems
- Passive systems
- Infinite-dimensional systems (e.g., PDE based systems)

* Application-Specific Techniques for

- Conservative systems (e.g. Molecular Dynamics)
- Computational fluid dynamics
- Structural analysis (e.g., condensation or sub-structuring)
- Micro-electro-mechanical systems (MEMS)
- Image processing
- Chemical kinetics

* Low-Order Modeling

- Proper orthogonal decomposition (POD)
- Wavelet techniques in dimension reduction
- Reduced-order modeling of distributed circuit elements

* Low-Order Design

- Low-order filter design techniques
- Controller reduction techniques

The deadline for submission of papers is March 31, 2003, and
the special issue is expected to be published in 2004.

Subject: Workshop in College Park on Incompressible Flows

A workshop on

"Perspectives on incompressible flows.
Comparison of different computational strategies"

will be held April 7-11, 2003 at the new Center for Scientific
Computation and Mathematical Modeling (CSCAMM) in the University of
Maryland College Park.

SCIENTIFIC CONTENT. The aim of the workshop, organized by S. Chen,
H. Elman, J.-G. Liu, E. Tadmor and D. Zhang, is to bring together
computational scientists working on diverse aspects of incompressible
flows, to compare notes on different solution strategies and to discuss
the potential advantages of blending different methods to form new,
more effective solution strategies in applications. Among the methods
to be discussed are
o variants of pressure-projection methods typically associated
with finite volume discretizations;
o solution algorithms associated with (mixed and stabilized)
finite element approximation methods;
o high order discretization approaches such as spectral methods
and associated domain decomposition solvers;
o grid-free methods such as particle methods and smoothed particle
o efficiency-oriented methods -- multigrid, fast multipole method,
vorticity-based methods...

Issues to be addressed include computational costs and ease of
implementation of the different discrete approaches, adaptive refinement,
utility in engineering codes, and rigorous convergence analysis.

project goals suitable to a general audience and highlights of
achievements possibly for a more specialized audience.


The program will be structured in special sessions, main invited
lectures and short presentations intended as an opportunity for young
researchers to present their work. Topics include but are not limited to:

* Online Mathematical Knowledge
* Mathematical Web Services
* Semantic Web Technologies for Mathematics
* Doing and Communicating Mathematics on the WEB
* Interactive Mathematics: examples, implementations, challenges
