    Designing airplane struts using minimal surfaces
    (2002-07) Alagoz, Dilek; Hoogendoorn, Stephanie; Kakollu, Satyanarayana; Valle, Sara Del; Moeller, Todd; Natarajan, Siva Kumar; Pencheva, Gergina V.; Sherman, Jason C.; Wise, Steven M.; Grandine, Thomas (mentor)
    A model for minimizing the effects of skin drag and pressure drag is constructed. We show that a simple scaling technique can be used to transform a dual, constrained minimization problem into a volume constrained surface area minimization. We discuss some successes and failures with implementing numerical methods for the problem.

    Modeling planarization in chemical-mechanical polishing
    (2002-07) Alagoz, Dilek; Hoogendoorn, Stephanie; Kakollu, Satyanarayana; Reznikoff, Maria; Schugart, Richard; Sostarecz, Michael; Borucki, Leonard (mentor)
    A mathematical model for chemical-mechanical polishing is developed. The effects of pad bending, fluid flow, and friction are considered. Fluid flow and friction effects are determined to be insignificant in the current model. Numerical results for the model including pad bending are presented and compared to experimental data.
