Subject: histoRicalg: Documentation and Transfer of Knowledge about Algorithms

For approximately the last year I have been developing ideas for ways
to document and transfer knowledge of older algorithms used by
R. These are mainly in Fortran, but some are in C, with the original
codes possibly in other programming languages. My efforts were
prompted by possibility of bugs in codes, which could be either from
the original programs or else the implementations. Two examples in
particular -- in nlm() and in optim::L-BFGS-B -- gave impetus to the
project, which I call histoRicalg. The R Consortium has awarded this
project some modest funding.

A preliminary web-site is at
As a first task, I am hoping to establish a "Working Group on
Algorithms Used in R" to identify and prioritize issues and to develop
procedures for linking older and younger workers to enable the
transfer of knowledge. Expressions of interest are welcome.

While active membership of the Working Group is desirable, given the
nature of this project, I anticipate that most members will contribute
mainly by providing timely and pertinent ideas. Some may not even be R
users, since the underlying algorithms are used by other computing
systems and the documentation effort has many common features. We will
also need participation of younger workers willing to learn about the
methods that underly the computations in R.

Subject: FEATool 1.8 with OpenFOAM GUI and Matlab CFD Interface

The FEATool Multiphysics MATLAB and Octave FEM Simulation Toolbox
version 1.8 is now available. In addition to being a fully integrated
FEA multiphysics toolbox, and interfacing with the FEniCS FEM solver
and external mesh generators such as DistMesh, GiD, Gmsh, and
Triangle, the highlight of the new version is introducing a fully
integrated and cross-platform OpenFOAM CFD GUI interface for MATLAB
and GNU Octave.

The new OpenFOAM MATLAB CFD interface allows one to conveniently setup
both laminar and fully turbulent incompressible Navier-Stokes CFD
problems all within an easy to use graphical user interface
(GUI). Featuring built-in CAD tools and (STL) CAD file import,
automatic mesh generation (with automatic 2D to 3D mesh conversion and
extrusion for 2D problems), FEATool to OpenFOAM case file conversion,
solver selection and control, as well as solution import with
postprocessing and visualization. As with all the FEATool MATLAB GUI
functionality, models can also be saved and exported as m-file CLI
functions where custom scripting and support for all MATLAB and Octave
functions and toolboxes is supported. With the added support for the
popular OpenFOAM CFD solver and FEniCS, high-performance multiphysics,
multi-simulation, and CFD modeling can now be all be conveniently done
within a single software interface.

Subject: New Book, Mathematical Models and Their Analysis

2018 / xx + 402 pages / softcover / ISBN 978-1-611975-26-0 / List Price

A great deal can be learned through modeling and mathematical analysis
about real-life phenomena, even before numerical simulations are used
to accurately portray the specific configuration of a situation.
Scientific computing also becomes more effective and efficient if it
is preceded by some preliminary analysis. These important advantages
of mathematical modeling are demonstrated by models of historical
importance in an easily understandable way.

The organization of Mathematical Models and Their Analysis groups
models by the issues that need to be addressed about the phenomena.
The new approach shows how mathematics effective for one modeled
phenomenon can be used to analyze another unrelated problem. For
instance, the mathematics of differential equations useful in
understanding the classical physics of planetary models, fluid motion,
and heat conduction is also applicable to the seemingly unrelated
phenomena of traffic flow and congestion, offshore sovereignty, and
regulation of overfishing and deforestation. The formulation and
in-depth analysis of these and other models on modern social issues,
such as the management of exhaustible and renewable resources in
response to consumption demands and economic growth, are of increasing
concern to students and researchers of our time.

Audience: This book is recommended for advanced undergraduates, early
graduate students, or anyone with a strong background in calculus and
ordinary differential equations, for use in mathematical modeling and
introduction to applied mathematics courses.

About the Author: Frederic Y. M. Wan has been a Professor of
Mathematics at the University of California, Irvine since 1995, where
he was also Chancellor for Research and Dean of Graduate Studies,
1995-2000. He has previously held positions on the mathematics faculty

Mathematics and Statistics at the University of British Columbia,
President of the American Academy of Mechanics (AAM), President of the
Canadian Applied Mathematics Society (CAMS/SCMA), and founding Chair
