数値解析・応用解析セミナー

8月17日(金) 16:00 -- 17:00 Craig C. Douglas (University of Wyoming, USA)
             ``Dynamic Tracking and Identification of Contaminants
               in Water Bodies Using Mutliscale Models and Sensors.''

  ＜研究発表要旨＞
We modify a well known mathematical model of fluid flow in water bodies 
in order to improve the computational accuracy over time. Our goal is to
backtrack observed pollution clouds in order to find the one or more 
polluters. We use a set of remote sensors and data assimilation on much
smaller grid within the large computational mesh. We solve a multiscale
interpolation problem on a coarse time scale that provides updates to the
predictions from our regular model. Over a sliding window of time, we see
far greater accuracy. The technique is similar to solving inverse problems, 
but less epensive.
  This is joint work over a period of years with Li Deng, Yalchin Efendiev,
Richard Ewing, Raytcho Lazarov, and Robert Lodder.
