  1. A Pursuit of Geometry-Centric Solutions to Engineering Problems

    Online Presentations | 27 Apr 2017 | Contributor(s):: Ganesh Subbarayan

    The main thesis of this talk is that a geometry-centric viewpoint during analysis of behavior is not only necessary to ensure the accuracy of the predicted shapes of boundaries and interfaces, but also enables efficient solution. Furthermore, I will demonstrate that an explicit parametric...
