  • Guillotine cuts 
    Mahajan, Sahil; Raman, Rajiv (Advisor) (2016-09-13)
    In guillotine cut problem, we are given non-intersecting convex sets in the plane and we are allowed straight line cuts. If a cut passes through an object, it kills that object. Can one always save a constant fraction or ...
  • Using smartphone-based accelerometer to detect travel by metro train 
    Vij, Megha; Naik, Vinayak (Advisor); Gunturi, Venkata M. Viswanath (Advisor) (2016-07-18)
    We look at the problem of using accelerometer in smartphones to detect whether the user is at a metro train station or in a metro train. Currently, we have solutions to detect simple activities, such as sitting or walking. ...
