Subject: Postdoc Position Available at Mississippi State University

A postdoctoral position is available in the Engineering Research Center at
Mississippi State University.  The position is part of the interdisciplinary
project "Novel Dynamic Scheduling Methods with Application to Computation of
Quantum Trajectories" funded by the new NSF research initiative in Information
Technology Research (ITR).  The project offers exciting opportunities for
research in scientific computing, numerical algorithms, and computational
quantum physics.

The position is available immediately for a period of one year, renewable to
two years.  Applicants must have or soon expect to receive a PhD in computer
science, computational physics, or applied mathematics, with a strong
background in parallel computing or numerical methods for solving Schroedinger
equations.

At the Engineering Research Center (http://www.erc.msstate.edu) the applicant
would have ample opportunity for interdisciplinary collaborative work and
interaction with scientists at other research centers and universities
throughout the United States.  Video conferencing is available to facilitate
the educational and scientific interaction with collaborators located at other
universities and research centers.  The applicant will have the opportunity to
participate in numerous conferences and workshops on and off campus to further
his/her education.

Interested applicants should send their applications (including curriculum
vitae, list of publications, names of references with their e-mail addresses),
by email (please use postscript of pdf formats only) to either Ioana Banicescu
(ioana@erc.msstate.edu) or Jianping Zhu (jzhu@erc.msstate.edu).

Important Dates and Deadlines:
    May 1, 2001 Early Registration and Abstract submission
    August 1, 2001 Confirmation and Program

Meshfree methods for the solution of partial differential equations gained
much attention in recent years, not only in the engineering but also in the
mathematics community.  One of the reasons for this development is the fact
that meshfree discretizations and particle models are often better suited to
cope with geometric changes of the domain of interest, e.g.  free surfaces and
large deformations, than classical discretization techniques such as finite
differences, finite elements or finite volumes.  Another obvious advantage of
meshfree discretizations is of course their independence of a mesh.  Mesh
generation is still the most time consuming part of any mesh based numerical
simulation.  Since meshfree discretization techniques are based only on a set
of independent points these costs of mesh generation are eliminated.  Finally,
the coupling of particle models to continuous models gained enormous interest
in recent years from a theoretical as well as from a practical point of view.

Among the most prominent meshfree discretization techniques are: 

     stochastic particle models, 
     smoothed particle hydrodynamics, 
     reproducing kernel particle methods, 
     partition of unity methods, 
     radial basis functions, 
     vortex methods. 

The aim of the workshop is to bring together european and american researchers
from different fields-inside and outside mathematics-not only to strengthen
the mathematical understanding and analysis of meshfree discretizations but
also to promote the exchange of ideas on their implementation and application.

Topics of interest in the workshop are: 

     analysis of meshfree methods, 
     implementational issues of meshfree methods, 
     coupling of particle models to continuous models, 
     industrial applications of meshfree methods. 

The four day workshop program will consist of invited lectures, contributed
papers and poster sessions.

If you are interested in contributing to this workshop, please submit an
abstract of about 300 words by e-mail to the contact address

    mailto:meshfree@iam.uni-bonn.de by May 1, 2001.
