Subject: Schwarz-Christoffel Toolbox for Matlab
Update of the Schwarz-Christoffel Toolbox for Matlab
I've recently completed some significant additions to the
Schwarz-Christoffel Toolbox for Matlab.
The Schwarz-Christoffel Toolbox for Matlab 4 is a collection of
M-files for the interactive computation and visualization of
Schwarz-Christoffel conformal maps. The Schwarz-Christoffel
transformation is a formula for a conformal map from the upper
half-plane to the interior of a polygon, which may have slits
or vertices at infinity. The transformation can also be modified to
produce maps from the unit disk, an infinite strip, or a rectangle,
or from the disk to the exterior of the target polygon.
Major features of the toolbox include:
Graphical input of polygons
Solution of the parameter problem for half-plane, disk, strip,
rectangle, and exterior maps
Computation of forward and inverse maps
Adaptive plotting of images of orthogonal grids for
visualization
Command-line and graphical user interfaces
Online and Postscript documentation
The toolbox requires Matlab 4.1 or later, except under MS-Windows,
where version 4.0 is sufficient. Little Matlab expertise is required.
Version 1.2 has several improvements over version 1.0, most notably
the ability to work with maps from a strip or a rectangle. This
capability is useful when dealing with elongated polygons. There are
also improvements in speed and in the graphical interface, including
the drawing routine.
The Schwarz-Christoffel Toolbox can be obtained by anonymous ftp to
ftp.cs.cornell.edu, in the directory pub/driscoll/SC-Toolbox, or at
the MathWorks ftp site, ftp.mathworks.com, in the directory
pub/contrib/misc/sct-12. Version 1.2 of the toolbox is available in
the shar file sct-12.sh, and the Postscript documentation is in the
file sct-guide.ps.

Subject: Looking for SMAC Navier Stokes Codes
Dear NA-Netters,
I am looking for codes implementing the SMAC (Simplified
Marker-and-Cell) for incompressible Navier Stokes equation in any
geometry and boundary conditions. Source codes in Fortran or
C are mostly convenient, but any other pointer or reference is also
appreciated.
Thanks in advance,

Subject: Matrix Spectrum Problem
Eigenvalues/ Matrix Spectrum problem
My colleague and I have been looking at a wave propagation problem
and currently are faced with the following type of matrix:
[ ]
[ 0 I ]
[ ]
[ -C -B ]
[ ]
where
I is the identity matrix
C is a diagonal matrix with positive entries
B is a symmetric matrix
How much can be said about the spectrum/eigenvalues of the above
matrix if no other information is known. (The general form of
the entries of C and B are known but the stated properties
seem to be the only apparent ones).
General enquiries amongst friends have
either drawn a blank or the response
that nothing definite can be said.
Alternatively, one might ask about the system
A'' + B*A' + C*A =0
where A is a vector and wonder about the stability theory.
Any useful references or ideas would be warmly appreciated.

However, we will also take this opportunity to change the cost of
student registration: it is now gratis. Please encourage students
to attend and/or submit a paper to the student competition!

begin by asking who wishes to speak and setting the Circus schedule
accordingly. To provide a more informal atmosphere for discussion,
there will also be time set aside for Workshops on specific topics
of interest. The schedule for the Circus and Workshops will be
determined each day according to demand.
STUDENT PAPER COMPETITION
Travel and lodging assistance will be awarded to students judged to
have the best research papers. Papers with original research due
mainly to the student must be received before December 1, 1994. They
must be singly authored and no more than 10 pages in length. Sending
only an abstract is unacceptable. A panel of judges will determine
the best papers. Authors of the three best papers will be given a
travel stipend, free lodging, and registration, and will be expected
to present their papers in a special session at the conference.
Several other students who participate in the competition may be
awarded free lodging and registration, depending on availability of
funds.

There will be morning and late afternoon lectures of approximately
25 minutes each. Evenings will be reserved for the Circus and
Workshops. Afternoons will be open for more informal workshops and

Subject: Post Doc at Surrey, UK
Postdoctoral Research Fellow
Department of Mathematical
and Computing Sciences
University of Surrey, UK
A postdoctoral research fellow is required to work on the project
`Numerical Investigation of Turbulence in the Complex Ginzburg-Landau
Equation', which is funded by the EPSRC for a period of 3 years and will be
supervised by Dr P. Aston and Dr M. Bartuccelli in the Department of
Mathematical and Computing Sciences, together with Dr P. Voke in the
Department of Mechanical Engineering.
The project involves the development of numerical methods suitable for the
accurate simulation of both hard and soft turbulence in the CGL equation.
The norms of the solutions will then be compared with analytical upper
bounds. The relationship between the hard turbulent solutions of the CGL
equation and the finite time singularities of the Nonlinear Schrodinger
equation in the inviscid limit will also be considered.
Applicants should have, or expect to obtain, a PhD and should have
experience in either numerical analysis or nonlinear dynamical systems
as well as being a competent programmer. Knowledge of Fortan and Unix would

CIAMP staff members currently have Australian Research Council funding for
a project entitled "Discrete optimisation algorithms for practical sequencing
and scheduling problems arising in the transportation industry."
The particular work being undertaken concerns algorithms for stochastic
vehicle routing problems and the use of parallel computers for a range of
methods appropriate for the combinatorial optimisation problems which arise in
the scheduling of vehicles and crew. Application areas considered so far
include airline crew scheduling, bus and crew scheduling, locomotive
scheduling and delivery vehicle scheduling.
The Centre is interested in hearing from suitably qualified people who may be
interested in visiting this year or next for periods of at least 3 months to
work on the project or who may be interested in applying for a post doctoral
position for 12 months. Experience with one or more of set partitioning,
Lagrangean relaxation or parallel algorithms for discrete optimisation
problems would be an advantage.
In the case of visitors, some support could be offered for people on leave from
their own universities who wish to work on the project.
