Prospective authors are invited to submit - after July 15, 2002 and prior to
September 30, 2002, - a paper of up to 1600 words on topics related to the
theme of the Session (PDF, Postscript, or Microsoft Word documents). Your
paper may contain up to 1600 words, plus up to four figures or tables (in
total). If the total number of figures or tables exceeds four, your word
count should be reduced by approximately 100 words per additional figure or
You must submit to the Session Organizer by email only (, two
files together in one email, that is:
First file: the manuscript (formatted to print on size A4, or 8.5 inch by 11
inch paper, see Guide for Authors, Your
paper must follow the detailed format given in the Format for papers. Second
file: a completed summary sheet (see Summary Sheet)
Papers should contain an abstract, conclusions and relevant references. All
communications must be in English and bear the names of all authors, their
affiliations and full mailing addresses.
Regular mail or courier, or fax submissions will not be considered.
Papers must not have been previously published or currently submitted for
publication elsewhere.

The conference proceedings will be published by Elsevier. Authors will also
be sent proofs for checking (anticipated January to March 2003). As the
Proceedings are being published to a fixed schedule, prompt return of proofs
is essential. The publisher reserves the right to publish papers directly
from the proof copy if authors have not returned their corrected proofs on
schedule. This is important to ensure that the Proceedings are available at
conference registration.

Conference Fellowship
As in the First Conference, about one hundred young researchers from any
part of the world will be fully supported to attend the Conference. A
Fellowship provides for all travel expenses, Conference fees, accommodation
expenses in M.I.T. on-campus housing, and a personalized Fellowship
Certificate. Fellowship awardees are expected to present a paper at the
Fellowship applicants must be less than about 30 years of age at the time of
the Conference, and must submit a short paper (of the form described in the
Call for Papers) and two letters of recommendation (typed on letter head,
faxed or email recommendations are not sufficient) together with the paper.
Applicants will be notified prior to December 15, 2002 (provided the
application was received prior to September 30, 2002) as to whether they
have been awarded a Fellowship.

September 30, 2002: Deadline for paper submission

Subject: Doctoral Position at the ETH Zurich

The Seminar for Applied Mathematics (ETH Zuerich)
announces opening of a

Doctoral Position

to participate on the project:

``Construction and Analysis of Numerical Methods in Image Processing''

The appointment will be for three years; successful participation
on the project will lead to PhD degree.

Successful applicants should have deepened knowledge of the theory
of partial differential equations, or calculus of variations and/or
(geometric) measure theory. Basic knowledge of numerical analysis of
PDEs is appreciated.

Goals in this project are to construct efficient schemes to approximate
measure-valued solutions of related nonlinear PDEs or minimization
problems, and to analytically prove their convergence properties.

Review of applications will begin immediately and will continue until
the position is filled.
