Evidence that XTR Is More Secure than Supersingular Elliptic Curve Cryptosystems
Abstract. We show that finding an efficiently computable injective homomorphism from the XTR subgroup into the group of points over GF(p2 ) of a particular type of supersingular e...

Extending the CG Model by Simulations
Abstract. Conceptual graphs (CGs) share with FOL a fundamental expressiveness limitation: only higher-order logics allow assertions of properties on predicates. This paper intends ...

Approximation by Conic Splines
Abstract. We show that the complexity of a parabolic or conic spline approximating a sufficiently smooth curve with non-vanishing curvature to within Hausdorff distance ε is c1ε...

Simultaneous Precise Solutions to the Visibility Problem of Sculptured Models
Abstract. We present an efficient and robust algorithm for computing continuous visibility for two- or three-dimensional shapes whose boundaries are NURBS curves or surfaces by li...
