Overview

Through the use of symbolic and graphical techniques, this book

explores parametric curves, interpolation and approximation, signal

theory (sampling, filtering, reconstruction, and the sampling theorem),

quadrature, and the solution of nonlinear equations. The emphasis is

on doing rather than proving, which makes it a good precursor to more

rigorous courses in scientific computation, signals and systems, and

computer-aided geometric design. A main theme of this book is that

there is a fundamental unity among these topics that symbolic and

graphical techniques can help to amplify.

More detail on the book, including table of contents, preface and index

is available via the WWW at the URL

http://www.dgp.toronto.edu/people/elf/ssgc.html

An extensive repository of courseware is also available.

I have developed a first/second year undergraduate course based on this

material, and have taught it for several years. In my department, it

is viewed as an introduction to mathematical computation that

complements a traditional introduction to computer science. I would be

happy to chat with potential instructors about putting together a

course based on my book. I can be reached at elf@dgp.toronto.edu, or

**Subject: Software for Hankel Transform Sought**

Can someone recommend robust software, in double precision

if possible, for evaluating the Hankel Transform

F(y) = integral(0 to 1) x*J_0(xy)*f(x) dx ?and y can be very large.

A concern is that the given function in my application has

a right-hand singularity,

f(x) = g(x)/sqrt(1-x*x), smooth g(x),

A teaching team at the Technical University of Denmark is looking for

public domain software for use in an introductory course on the finite

element method for solving 2-D partial differential equations. The course

runs fulltime for 3 weeks and is primarily devoted to the development of

FORTRAN codes for problem solution.

Specifically, we would like to find routines for pre- and post-processing;

i.e., automatic (graphic) mesh generation and graphical presentation

of the results. The computational environment includes a HP 9000 (Model 700)

running HP-UX (Unix) v. 9.05 . Fortran is the preferred programming language.

Any help in locating FEM software for this purpose would be much

appreciated.

Hi,

I am looking for a multiresponse nonlinear least square fitting program

(preferably in PASCAL or C++) that can be used to find the desired

parameters (such as thermal diffusivity, thermal conductivity or heat

capacity) in a known nonlinear model (solution of the heat conduction

equation - sums of Bessel functions and exponentials).

The data (temperature) to be fitted depend on time (equidistant) and the

position and they were taken from 4 thermocouples attached to

the sample.

I appreciate any assitance you may be able to offer.

Dear Colleagues,

As part of the ScaLAPACK project we intend to include software

for the solution of banded linear systems. Since algorithm

performance is greatly impacted by the characteristics of the

system being solved, we solicit your input to help us design our

software for the kinds of systems found in practice.

ScaLAPACK is a freely available software package for scalably

solving problems in numerical linear algebra on distributed

memory parallel computers. If you have a need to solve large

banded linear systems, now is the time to provide us with your

requirements.

We ask you to fill out the following short questionnaire. If

you have colleagues(engineers, physicists, or researchers in

other disciplines) who may not normally read NA-NET but who may

be working with banded matrices, we encourage you to pass this

questionnaire on to them.

We hope to receive your responses within the next few weeks. A

summary of responses will be posted to NA-NET.

________________________________________________________

| Questionnaire on the use of Banded Linear Systems |

--------------------------------------------------------

We are concerned with applications in which a requirement is the

solution of the linear system A*X = B in which A is an n x n

banded matrix. A matrix is banded if there are two parameters bl

and bu such that

That is, elements in the lower triangle more than bl elements from

i > j & (i-j) > bl -> A(i,j) = 0, and

j > i & (j-i) > bu -> A(i,j) = 0.

the main diagonal are identically zero and likewise for elements in

the upper triangle more than bu elements from the main diagonal.

Elements of the main diagonal may or may not be zero depending on

other characteristics of the problem.

The matrices X and B are n x k matrices. The j-th column of X,

X(:,j), is the solution of the system with respect to the right

hand side B(:,j).

If your work involves the solution of such systems, we would

like to ask you to fill out the following questionnaire and

e-mail to: cleary@cs.utk.edu

--------------------------Snip Here-----------------------------

Personal Details

1) Your Name:

2) Your Affiliation:

3) The nature of your project/research:

Problem characteristics

3) How many equations (n) do your banded linear systems typically have?

4) How many diagonals above/below the main diagonal (bl, bu) are non-zero?

5) How many right-hand sides (k) do you typically have at once?

6) Are your matrices symmetric/Hermitian? If so, are they

positive definite ?

7) Are your matrices diagonally dominant ? Any other

characteristics ?

7) Do you have any preference for iterative algorithms or direct algorithms ?

If direct methods are used, is partial pivoting required and

satisfactory for numerical stability?

Problem generation

8) How do banded linear systems arise in your application, in

particular, are the banded systems typically generated as stand-alone

problems, or as a step in a longer series of calculations?

10) Are you currently using parallel computers to solve these problems?

11) If you are using a parallel computer for these problems,

where are the matrices A, B and X located on entry into a

system solution routine ? Are they on disk(s), in a single

processor's (or host's) memory, or distributed amongst the processors?

If the latter, what distribution do you use?

POST-DOCTORAL POSITION AVAILABLE FOR STUDIES OF

NUMERICAL HYDRODYNAMICS OF UNDERWATER VEHICLES

The project for this position involves:

1. Adding lifting elements to a potential based BIEM panel code,

2. Determining forces and moments on underwater vehicles under

the influence of solid bottom boundaries and a free surface

upper boundary with sea waves on it,

3. Developing both theoretical and semi-empirical methods to

determine the net forces and moments provided by jet and

tunnel thrusters to an underwater vehicle with forward speed

and in the proximity of rigid and free surfaces.

4. Generating mathematical models of surface-induced forces and

moments on underwater vehicles and adding them to existing

computer programs for the maneuvering of underwater vehicles.

Applicants should be first and foremost fundamentally strong in

the cognizant hydrodynamic and mathematical fields, be fully

competent in the associated programming, and be familiar with

programming and use of personal computers, UNIX workstations and

supercomputers. Most of the programming is done in Fortran 77,

but some parallel machine programming may be in Fortran 90 and

some graphical I/O may be in C.

The project personnel will include a faculty member, 2 or 3

graduate students and the post-doc to be added.

Interested applicants should send a resume and names, street and

email addresses and phone numbers; by mail, by Fax or by an

e-mail text file (no postscript files or other forms requiring

translation please) to:

FELLOWSHIP OPPORTUNITY FOR NUMERICAL PERSON IN NUMERICAL GEOPHYSICS

I am a geophysicist at Dept. Geological Science, Univ. Durham, U.K. and

have been working for several years making repeated survey measurements

in Iceland using a GPS satellite technique. The mid-Atlantic spreading

plate boundary passes through the middle of Iceland, and thus there is,

on average, several cm of "plate" movement in Iceland, along with large

earthquakes and volcanic eruptions. We now have an extensive set of

measurements of these movements.

Somewhat surprisingly, we have found that the motion is not regular and

"plate-like" but highly variable. What happens is that every few

hundred years there is a big event, e.g. a very large earthquake, which

causes deformations of several metres locally in the Earth's crust. The

shallow part of the Earth is well-modelled by an elastic layer about 10

km thick overlying viscoelastic material that may obey a law such as

power-law creep or Newtonian viscoelasticity. In such a structure,

large, local movements do not immediately affect distant areas, but

gradually propagate away from the source over time.

We have recently completed modelling of our results using an analytical

method that calculates motion in an elastic plate overlying a Newtonian

viscoelastic half-space. We have got some tremendously interesting

results that we expect will generate several eye-opening publications

on tectonic motions.

Our results show that the next step is to do modelling, and/or develop

new modelling tools, that can take account of three-dimensional

structural heterogeneity and more complex rheologies. A finite element

approach is one, but not the only candidate. The objective would be

to develop a powerful tool for modelling the deformation of the Earth's

crust and outer layers on a regional scale, and to explain and predict

the structure and behaviour (including the recurrence of great

earthquakes and volcanic eruptions).

I am very interested in working with a numerical person on this

project. I myself am a geophysicist, not a mathematician, so I am

looking for a colleague who might provide the latter expertise. The

Royal Society Dorothy Hodgkin scholarships have come to my

notice, and my department and project certainly would fit the

requirement of "departments/disciplines where (women) are currently

under-represented at the post-doctoral level". Is there anyone out

there who is interested? A nice possibility would be for a person to be

jointly attached to my department and the maths or physics department

here - then it would be interdisciplinary too.

Durham is a wonderful old historic town with a collegiate university.

You'd love it here.
