Subject: Rounding Control doesn't work on MacBook

I bought a MacBook Pro laptop in Spring 2007, with the Intel dual-
core processor. I intend to use it for research in interval
computation. But Rump's INTLAB, on startup, said "Sorry, can't switch
rounding mode".

So I wrote a simple C program using the fesetround() and fegetround()
functions mandated by the C standard (N1124), and ran it with GCC
4.0.1. The output indicates (a) one can't change rounding mode and
(b) it is set to "round towards zero", i.e. archaic chopping.

I can believe (a) might happen with GCC, but I cannot believe (b).
Can anyone shed light on this and tell me a workaround, so I can do
real interval work on my elegant machine?

Subject: PDE software

We recently completed the coding and testing of a library of Matlab routines
(functions) for the numerical method of lines (MOL) integration of ODE/PDE
systems. The software is organized into four subdirectories:

(1) The MOL routines (based on finite differences (FDs) of orders two
to ten, for first and second derivatives, including Dirichlet, Neumann
and third type boundary conditions).

(2) A series of routines to explain the origin of the FDs.

(3) A series of routines for applying the FDs to test functions with known
analytical derivatives, e.g., polynomials of various orders and exponential

(4) A complete MOL application to a linear PDE (Fourier's second law),
including numerical and graphical output and a comparison of the numerical
and analytical solutions.

This software is available on a CD, with related printed material, through
a request directed to Please provide a postal mailing
address. A small package will be sent by US First Class mail or
air mail.

Subject: Consulting efficient B-spline surfaces' intersection algorithms

Hi, All experts

Now the product design and manufacturing is approaching the
nano-scale(0.000001), current numerical accuracy of B-spline
surfaces' intersection of CAD/CAM is not enough (only 0.001). And a
more accourate and speeding intersetion algorithm on B-spline
surfaces' intersection is required.

Therefore, does any expert have any some new insights or suggestion
on this issue. Any comments or relating literatures are preferred.

Subject: Industrial inverse problems workshop/sandpit at Leeds, Mar 2008

Announcement of the Industrial Inverse Problems Workshop/Sandpit,
University of Leeds, 17-18 March 2008

A Knowledge Transfer Workshop/Sandpit on Industrial Inverse Problems will
be held on 17-18 March 2008 at the University of Leeds.
It is intended that the workshop/sandpit will commence on Monday 17 March
around 11.15 and finish on Tuesday 18 March
around 12.30.

The purpose of the meeting is for industrialists and academics to identify
inverse problems of common interest.
Inverse Problems seek to identify causes from given effects and as such
they are at the heart of many physical phenomena and any advance into the
subject should be encouraged.

The Workshop/Sandpit will follow the format of presentations from industry
by way of introducing the problems on the first day,
followed by intensive work on the problems by groups (academic and
industrial) during the next day.

The workshop will be facilitated by the Industrial Mathematics Knowledge
Transfer Network.

As an outcome of this activity it is hoped that a rapport between
academics and industrialists will be established and cemented through
possible grant proposals for PhD Studentships / CASE Awards and Post-docs
to be submitted to the EPSRC or to other foundations.

Academic participation is open to all members of the inverse problems
community or related subjects, including postgraduate students, for whom
the proposed activity provides an excellent training in oriented research.

Please note that there are no fees to be charged for participating at the

Subject: Conference on The Legacy of John Crank, Jul 2008 (corrected URL)

Conference on the Legacy of John Crank
Developments in Time Dependent PDEs, Diffusion and Free Boundary
Problems 10 - 11 July 2008 Brunel University, Uxbridge, England
Organisers: J. Ockendon, C.M Elliott and J.R. Whiteman

A two day conference will be held at Brunel University, Uxbridge, UK to
consider the influence that the work of John Crank has had on the
numerical solution of time dependent PDEs, on the modelling of diffusive
processes and on free boundary problems. The focus of the meeting will
be on the state-of-the-art of the subject and on future developments and
applications, including industrial applications.

John Crank (1915 - 2006) originally worked in industry on the modelling
and numerical solution of diffusion in polymers. In 1943, working with
Phyllis Nicolson on finite difference methods for the time dependent
heat equation, he proposed the Crank-Nicolson method which has since
been incorporated universally for the solving of time dependent
problems. John Crank died in October 2006 and the purpose of this
meeting is to consider the legacy that he left to the numerical solution
of partial differential equations and in particular to consider future
developments and applications in the field.

Subject: Postdoc position in applied mathematics INRIA Rhone-Alpes. France.

Numerical methods for Fillippov's systems and piece-linear systems with
applications in Mechanics and Biology.

Filippov's systems and piece-linear dynamical systems are involved in
numerous applications fields ranging from frictional mechanical systems,
electrical circuits with ideal components to genetic regulatory networks
in biology. The objectives of this post-doctoral position are to study
and to understand some reformulations of Filippov's systems and
piece-wise linear systems into the complementarity formalism to provide
new mathematical tools for analysis and new algorithms for simulations.
Firstly, the reformulation will be extensively studied from the point of
view of the mathematical well--posedness, in showing the equivalence of
the notion of Filippov's solutions and complementarity solutions.
Secondly, the existence and uniqueness question will be discussed for
the time-discretized problem. Finally, the implementation of the
algorithm will be addressed in the Siconos framework}. Required skills are a) strong
background in dynamical systems and
applied mathematics and b) significant experiences in scientific
computing in C and C++ for the implementation.
