- Research interests:
The disseration research I have proposed involves the Application
of Parallel Algorithms to Problems in Satellite Geodesy. The main
focus of the research is the recovery of geoid coefficients. The
data types to be imployed are satellite gradiometry data, satellite
altimetry data, and satellite-to-satellite tracking data. I hope
to show that the implementaion of MPP methods will greatly increase
the size of gravity field which can be recovered.
- Possible semester project:
Most of the computation in the research described above involves the
solution to a linear least squares problem. Past research has shown
that the prefered solution methods is by orthogonalization techniques.
A possible semester project would be an "efficient" implementation
of either a Given's Rotations or a Householder Transformation algorithm.
I would be leaning toward the Householder since the observations
can, in general, be processes independently and, in general, not
across processors. Thus, I am left with a batch of observations
to be folded into the information matrix.
