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...

Curvature analysis of pattern transformation manifolds
Transformation manifolds are quite attractive for image analysis applications that require transformation invariance properties. The geometric structure of a transformation manifo...

Practical quad mesh simplification
n this paper we present an innovative approach to incremental quad mesh simplification, i.e. the task of producing a low complexity quad mesh starting from a high complexity one. T...

Exploiting Spatio-Temporal Correlations in MIMO Wireless Channel Prediction
— We investigate prediction algorithms that exploit both temporal and spatial correlations in MIMO correlated narrowband fading wireless channels. We first derive the optimal tw...

Single-Database Private Information Retrieval with Constant Communication Rate
We present a single-database private information retrieval (PIR) scheme with communication complexity O(k+d), where k ≥ log n is a security parameter that depends on the database...
