TOPIC: The Cell Discretization Method for Partial Differential Equations
ABSTRACT: A new method for discretizing partial differential equations has
been developed which is more general, and hence may be more suitable for
certain classes of problems than the Finite Difference or Finite Element
methods. Although it is based on a partitioning of the problem domain into
subdomains ("cells") and on a variational formulation, as is the Finite
Element Method, the similarity between the algorithms ends there. The cell
method admits of much more general kinds of intracell basis sets, and the
interface collocation is quite different, being based on sequences of
moments of the interface discrepancies over the interfaces.

Joint RIACS and CR Branch seminar
SPEAKER: Donald Allison

Blacksburg, Virginia
TOPIC: Fast Geometric Algorithms
ABSTRACT: The emergence of computational geometry as a discipline has been
strongly motivated by the number of application areas such as computer
graphics image processing and remote sensing that require manipulation of
objects in a real time environment. Research in computational geometry may
be classified into four main categories: 1) minimization and maximization
problems, 2) inclusion problems, 3) intersection problems, and 4) closest
point problems. In this seminar several problems from category 1 will be
discussed.
