Subject: Announcing new open source software, IMTEK Mathematica Supplement

The IMTEK Mathematica Supplement, or IMS for short is an open source
Mathematica add-on and provides a wealth of packages and tutorials from a
variety of application areas, but with a strong focus on Finite Element
Computations. The IMS is a continuous project at the Chair for
Microsystem Simulation, Department for Microsystem Engineering (IMTEK),
University of Freiburg, Germany. The IMS user group is supported through
a mailing list, which can be accessed at the IMS web site:

Basically, the IMS has three main foci:
1) To provide useful Mathematica computation, visualisation and simulation
packages and their documentation
2) To provide easy to use, hands-on tutorials
3) To extend the capability to import and export CAD data formats with
interface packages.

It is important that IMS follows good design principles. The
interoperability of commands has received great attention during the
design process. Two core data structures extend the Mathematica
complement: the imsNexus and the imsSystem.

imsNexus is a Graph like data structure which is used to represent
computational meshes, circuit net lists or other connectivity based
domains. A variety of differential operators may be applied to these
objects (elements) and global equations systems can be built from them. Such
equation systems are represented by the imsSystem data structure.

An imsSystem - no matter whether it is built from within IMS or is read in
from an external source - can then be model order reduced or time

With about 50 numerical packages, 10 interface packages and about 10
tutorials, the IMS extends Mathematica in the areas of Computational
Geometry, Data Structures, (Partial) Differential Equation Systems and a
large set of Utilities. Several Lectures, Tips and Application Examples
are also provided.

We hope to have you excited about the contents of IMS. Have a look, it is
only a download away:

Subject: New Book, Financial Modeling of the Equity Market

Frank J. Fabozzi, Sergio M. Focardi, Petter N. Kolm: Financial Modeling of
the Equity Market - From CAPM to Cointegration
651 pages, Hardcover, ISBN 0-471-69900-4, John Wiley, January 2006

Financial Modeling of the Equity Market is a comprehensive, up-to-date guide
to the modeling of equity portfolios. The book is intended for
mathematicians, quantitative analysts, practitioners, and students of
finance. Without sacrificing mathematical rigor, it presents arguments in a
concise and clear style with a wealth of real-world examples and practical

This book describes the major approaches to single-period return analysis,
including modeling, estimation, and optimization issues. It covers both
static and dynamic factor analysis, regime shifts, long-run modeling, and
cointegration. Estimation techniques, including dimensionality reduction,
Bayesian estimates, the Black-Litterman model, and random coefficient
models, are also covered in depth. Important advances in transaction cost
measurement and modeling, robust optimization, and recent developments in
optimization with higher moments are also discussed.

Subject: Mathematical Software Engineer Position, AspenTech Inc, Boston, Mass., USA.

The role involves the research, development and maintainence of Aspen Open
Solvers (AOS), AspenTech's corporate component for the development and
deployment of mathematical software for engineering and supply chain
products, including Aspen Plus, Aspen Custom Modeler, Apollo Controller and
Aspen OSE. AOS is a set of C++ and .net interfaces for deploying linear,
non-linear equation and non-linear programming solvers, and is to be
extended to differential-algebraic equations and mixed integer programming.

We are looking for a talented software engineer with very strong
mathematical skills to work as part of a small team on AOS. The role
involves design and development of new capabilities for AOS and working with
development teams that use AOS in their products. Development is on Windows
using mostly C++ with some FORTRAN and .NET.
It is important that the candidate has a solid mathematical background,
ideally with experience in developing and supporting industrial strength
mathematical codes. The role involves working across a broad range of solver
technologies, including sparse linear solvers, non-linear algebraic solvers,
nonlinear programming, differential-algebraic solvers, control design and
parameter estimation, so extensive knowledge of one or more of these areas
is required and the candidate will be expected to broaden their skill base
to cover all areas.
As part of the role, the candidate will learn about the modeling
technologies and products used by AspenTech and its clients and will be
expected to support existing AOS solvers and work with product teams to
resolve solution engine problems.
Initial training may require some travel to the UK.
There may occasionally be the opportunity to work on external

* Experience of developing numerical solvers for industrial software
* Strong mathematical and numerical computation skills.
* Experience in developing OOD technical software using C++
* Knowledge of FORTRAN or .NET beneficial.
* Knowledge of solution technologies for equation based simulation would be
a distinct advantage.

MS/Phd in mathmatics or engineering.
