Constrained Projection Approximation Algorithms for Principal Component Analysis
Abstract. In this paper we introduce a new error measure, integrated reconstruction error (IRE) and show that the minimization of IRE leads to principal eigenvectors (without rotat...

Performance analysis of single relay selection in rayleigh fading
We provide closed-form expressions for the outage and bit error probability (BEP) of uncoded, threshold-based opportunistic relaying (OR) and selection cooperation (SC), at arbitra...

Concrete Memory Models for Shape Analysis
This paper discusses four store-based concrete memory models. We characterize memory models by the class of pointers they support and whether they use numerical or symbolic offset...

Performance Analysis of Selection Relaying Schemes over Different Fading Environments in Wireless Networks
In this paper, two selection relaying schemes are proposed and compared with each other in terms of packet error rate (PER) and diversity order. Moreover, the comparison is perfor...

A Fast Multigrid Implicit Algorithm for the Evolution of Geodesic Active Contours
Active contour models are among the most popular PDE-based tools in computer vision. In this paper we present a new algorithm for the fast evolution of geodesic active contours an...
