Primality Proving Using Elliptic Curves: An Update
In 1986, following the work of Schoof on counting points on elliptic curves over finite fields, new algorithms for primality proving emerged, due to Goldwasser and Kilian on the on...

Extending the Z-Width of a Haptic Device Using Acceleration Feedback
Abstract. This paper proposes a nonlinear controller to extend the Zwidth of a haptic device. A time-domain passivity analysis of the Z-width diagram leads to the new haptic contro...
