**Subject: Seeking Reference on Combustion Problem**

There is a simple combustion problem that can be modelled as

\frac{\partial u}{\partial t}=

\frac{d^2u}{dx^2} /a^2

+ [{1-x}/{2u} - (1-1/u)] [{1+x}/{2u}-(1-1/u)]

e^{\theta(1-\frac{1}{u})}}/{\theta }

It describes the steady - state combustion of two gases meeting in

a gap between porous walls a distance $2a$ apart. Fuel diffuses in at

one wall, oxidant at the other and there is a zone of reaction

in the middle, dying out towards each wall. Boundary conditions

are u(\pm 1)= 1.

Here x is the scaled distance from one of the walls and

u is the scaled temperature. Finally,

$\theta$ is a physical property of the two gases involved.

Compared to other combustion models this one is very simple. So

it is rather interesting for paedagogical purposes.

Unfortunately I do not have any published references. Can one

of the NA - netters help me?

Many thanks in advance,

**Subject: Multi-grid Methods for Biharmonic Equation**

I am interested in multigrid methods for solving the biharmonic equation

on unstructured 2D triangular meshes and am wondering if anyone has any

experience in this problem that they might be willing to share. In particular,

I am interested in solutions to the biharmonic equation that arises from

the equations for creeping flow (Stoke's equations). The fluid itself has a

strongly temperature-dependent viscosity that may vary sharply over short

distances (relative to the size of the compuational domain). Thus, my

biharmonic equation would have a viscosity term embedded within it.

Thanks in advance for any help!

**Subject: Updated AMPL/Solver Interface**

Now (finally!) available is a reorganized AMPL/solver interface

library that offers significant enhancements for support of

nonlinear solvers:

-- Detection of partially separable structure: automatic

recognition of a nonlinear function as the sum of terms

that depend on only of few variables each (possibly after

a term-dependent linear change of variables).

-- Computation of 2nd derivatives: use of the partially

separable structure to efficiently compute Hessian-vector

products and explicit Hessians (of the Lagrangian function

in a nonlinear programming problem).

New utilities make interfacing with solvers -- both

linear and nonlinear -- easier. An expanded set of example

interfaces includes a long-promised interface with LANCELOT,

as well as a MATLAB interface.

AMPL is a language and modeling environment for expressing and

manipulating linear and nonlinear programming problems. Much

more information is available from the AMPL web site,

http://www.ampl.com/ampl/

which offers both a Postscript file,

ftp://netlib.bell-labs.com/ampl/REFS/hooking2.ps.gz

and a corresponding HTML file,

that describe the updated solver interface library and give

**Subject: Intellectual Property Rights**

In NA Digest, V. 97, # 12, I posted a query about

--what rights Universities and Colleges have or appropriate themselves

regarding software which is brought to the institution by a new hire,

who subsequently turns it into a commercial product;

--in general, what to expect as far as property rights of academic

institutions, in particular as pertaining to developing commercial

software, and what to watch for in this regard.

The following is taken from a summary of my impression of the

situation based on the replies of Grzesiek Adamiec, Brian Borchers,

George F. Corliss, Henry Greenside, Steve Hammond, Russ Merris,

Jonathan R. Shewchuk, Gio Wiederhold and someone wishing to remain

anonymous, all of whom I thank. The unabridged version, including

pointers to additional information, is found in the newsletter

Concerns of Young Mathematicians, Volume 5, Issue 11 dated 23 April

1997, available on the web at the YMN Newletter Archive

http://www.math.usouthal.edu/ymn.html and by anonymous ftp to

ftp.ms.uky.edu in pub3/mailing.lists/ymn-list.

The big picture is that:

++All may be negotiable. Consult with a knowledgeable lawyer.

++The rights of academic institutions over software developed while

one is at their employ vary greatly from institution to institution,

and within institutions from job title to job title. In some cases

they extend to software developed by students.

++A rule of thumb is that anything developed on your own time using

your own equipment (as opposed to "university owned or maintained") is

your intellectual property. Keeping the development work off the

institution's computer network is a good idea. So is keeping it off

the institution's office space.

++Nearly all universities have partial ownership of software developed

specifically under an academic grant, but many share ownership with

the inventor, and don't claim ownership of software that wasn't

developed with the aid of grant money or significant university

resources. A few universities have policies assigning themselves full

ownership and royalties for anything their employees do.

++The situation is complicated by the fact that policies seem to be in

flux: PREPARE FOR TURNS FOR THE WORSE.

++The best time to negotiate and record exceptions to institutional

rules (including possible future changes in policy) is at hire time,

before signing an employment contract. Utter formality in these

matters is often unnecessary, but there needs to be a paper trail.

++As far as previously developed software goes, things are equally

variable. Have it recorded (in writing, of course) as early as

possible (preferably at hire time) that your preexistent software

products Widget and Gadget are off limit to the institution no matter

what, or under conditions satisfactory to you. Prior work should be

disclosed before employment, to protect it from claims. If the work is

a substantial reason for the hire, and will be continued, then a more

specific contract is advisable.

++Watch what you sign away! Be even more careful with industry.

**Subject: Interface of Computing Science and Statistics**

Final Announcement: INTERFACE '97

1997 Themes: Data Mining, Massive Data Sets, Environmental Science

The 1997 Symposium on the Interface of Computing Science and Statistics

will be held May 14-17, 1997 at the Houston Medical Center Holiday Inn

Hotel in Houston, Texas. The Symposium is being organized around the theme

of "Mining and Modeling Massive Data Sets In Science, Engineering, and

Business", with a sub-theme of multimedia education and quantitative

environmental science. The conference is sponsored by the Interface

Foundation of North America, a non-profit educational corporation. The

Statistics Department at Rice University is hosting the meeting with Dr.

David W. Scott as chair.

Dr. Jerry Friedman from Stanford University will give the keynote address.

The invited program includes some thirty sessions on topics including

virtual reality, marketing applications, multimedia education, numerical

methods, pattern recognition, visualization, mapping, environmental

statistics, wavelets, dimension reduction, computational biochemistry,

Bayesian methods, networks and clusters of workstations, virtual

departments, and information retrieval for massive data sets. The list of

invited speakers includes representatives from academia (Rice, CMU, UW,

Baylor, others), industry (IBM, SGI, SAS, Bellcore, others) and government

(USDA, JPL, Census, DOD, others) and includes a substantial number of

international speakers and participants (Berlin, Glasgow, Belgium, Finland,

others).

For many years advances in statistics and particularly statistical

computation have been driven by the general demands of industry. The

explosion of on-line resources and performance-price computer power has

dramatically increased expectations of what computational and statistical

scientists can provide. Data warehousing is a new trend in industry which

is intended to provide information

support to all segments of a business. Government is moving to provide

on-line access to many of its databases. These databases are approaching

terabyte size. This explosive growth is being matched in many academic

research labs, libraries, among others. The problems of efficiently and

effectively searching and modeling based on such massive data sets are the

focus of the 1997 Interface symposium. Many traditional statistical and

computational tools have been brought to bear on these types of problems.

Innovative visualization methods, where possible, often shed insight on

underlying structure. Novel computational

paradigms, such as neural nets and Bayesian methods and artificial

intelligence tools, are required in order to even begin to understand and

model the data. There are a wealth of ad-hoc techniques developed by both

statisticians and computational scientists. An active discussion, between

subject matter specialists and statistical and computational practitioners

is sure to lead to a fruitful interchange. Our intention is to foster such

a dialog via the Interface conference.

**Subject: Studentship at University of Bath**

Postgraduate Studentship - University of Bath

School of Mathematical Sciences

Applications are invited for a three year postgraduate studentship

funded under the UK Engineering and Physical Sciences (EPSRC)

Cooperative Awards in Science and Engineering (CASE) Scheme. The

cooperating body is AEA Technology, Harwell, Oxford, UK and funds are

available to support a PhD student working on the topic:

Parallel Algorithms in Groundwater Flow

This project is concerned with the parallel solution of linear systems

arising from finite element discretisations of two- and

three-dimensional models for groundwater flow coupled with the

transport of salinity. AEA Technology has written and markets the

code NAMMU (``Numerical Assessment Method for Migration

Underground'') which is used commercially on a range of pollution

control applications.

Mathematically the project concerns the development and

implementation of parallel iterative methods for mixed finite element

discretisations of partial differential equations describing

groundwater flow, and in particular for the coupled system which

arises when nonlinear salinity effects are included.

Compuationally it is envisaged that the student will

implement these methods using the approach of the DOUG (Domain

Decomposition on Unstructured Grids) package recently developed at

Bath. Details of this package, which uses the message passing system MPI,

are available at http://www.maths.bath.ac.uk/~mjh/doug.

At present this package solves standard finite element

discretisations of PDEs in 2D and 3D. One of the

chief initial computational tasks will be to extend it to mixed

finite elements. Computing for the project will be done at the

University of Bath and at AEA Technology, to which the student will

make regular scientific visits.

The remuneration provided by this studentship will be 5,295 pounds from EPSRC

plus 2,355 pounds from the cooperating body and the student will also

have the opportunity to undertake some paid part-time tutoring duties at the

University of Bath.

Applicants for this studentship should have or expect to obtain the

equivalent of a 2(i) Honours Degree or better in a numerate

discipline, and should have some experience in

numerical analysis, differential equations and numerical computation.

Applications from suitably qualified students with mathematics,

**Subject: Postdoctoral Position at University of Bath**

Postdoctoral Research Assistant - University of Bath

School of Mathematical Sciences

Applications are sought for a United Kingdom EPSRC funded one-year

position to work on domain decomposition techniques for the iterative

solution of elliptic PDEs on unstructured grids.

The project is to extend the work of a previous project which produced

the ``DOUG'' package for parallel iterative solution of elliptic problems,

details of which can be found at http://www.maths.bath.ac.uk/~mjh/doug.

The DOUG package solves PDEs by iterative methods with domain

decomposition preconditioning and is implemented in parallel using MPI.

Very good speed-ups have been obtained on dedicated parallel machines

such as the SP/2, as well as on ethernet clusters.

At present full additive Schwarz preconditioners are implemented and

tested in 2D only. The main aim of the present project is to extend the

full preconditioning technique to 3D problems, and in particular to

implement and test an appropriate unstructured coarse grid generation

procedure in that case.

For this work applicants should have an interest and experience in

large scale scientific programming, preferably in Fortran. Experience

in parallel programming using message passing techniques would be a distinct

advantage.

Possible extensions of the main aim of the project

include the parallel solution of mixed finite element discretisations of

groundwater flow problems arising from industrial applications and/or

extensions of a recent theory describing the performance of Schwarz methods in

the presence of highly discontinuous coefficients in irregular

geometries. Related theoretical work arising from the DOUG project can be

viewed at Reports 9608 and 9619 on

http://www.maths.bath.ac.uk/Maths_Group/preprints.html

The position is available on or as soon as possble after September 1st

1997 for one year.

The appointment will be at the Grade 1A level and the salary will be

around 16.6K pounds, subject to confirmation and depending on age and

experience.

Further details of the project may be obtained

from the supervisor, Dr Ivan Graham, School of Mathematical Sciences ,
