On Tuesday May 7, from 12 to 1pm in NS2 room 1201, the Mathematics Department will host a great seminar talk for undergraduates. UCI Professor D. Dabdub, an expert in mathematical modeling of air pollution dynamics, will talk about *Atmospheric Chemistry, Parallel Computing, and Applied Mathematics*.
Pizza will be served.
 
Atmospheric Chemistry, Parallel Computing, and Applied Mathematics
Scientific studies have shown that human exposure to high ozone and
aerosol concentrations can impair lung functions in people with existing
respiratory problems, and can cause chest pain and shortness of breath
even in the healthy population.  Furthermore, air pollution produces
undesirable effects on animals, vegetation, and materials.  The ozone
problem raises serious concerns, as over 30 major urban areas across the
country still do not comply with the national standard.  Abatement
planning is complex.  Several key aspects such as emissions control are
best addressed through the use of ambient air quality models.

This talk will describe recent advances in our knowledge of atmospheric
sciences through the use of advanced computer systems, new developments of
mathematical air quality models, and novel parallel computational methods
and computational environments.  In addition, newly developed parallel
algorithms used in the numerical solution of hyperbolic systems will be
presented.
