Ear recognition is an emerging biometric technology. This paper proposes a new ear recognition method based on SIFT(Scale-invariant feature transform) and Harris corner detection. Firstly, Harris corner points and SIFT keypoints are detected respectively. Then taking Harris corner into the SIFT algorithm to calculate their descriptor as the image feature vectors. Finally the feature vectors are...

Harris recurrence is a widely used tool in the analysis of queueing systems. For discrete-time Harris chains, such systems automatically exhibit wide-sense regenerative structure, so that renewal theory can be applied to questions related to convergence of the transition probabilities to the equilibrium distribution. By contrast, in continuous time, the question of whether all Harris recurrent ...

Distal femoral physeal fractures are not common but have a high rate of complications. They generally follow one of the patterns described in the Salter-Harris classification. We present a case of combination of Salter-Harris type III and type IV injury. Our case was a 15-year-old boy who had a motor vehicle accident. There was swelling, ecchymosis, severe pain, and valgus deformity, because of...

A short proof of the Harris-Kesten result that the critical probability for bond percolation in the planar square lattice is 1/2 was given in [1], using a sharp threshold result of Friedgut and Kalai. Here we point out that a key part of this proof may be replaced by an argument of Russo [6] from 1982, using his approximate zero-one law in place of the Friedgut-Kalai result. Russo’s paper gave ...

In recent years, Sam Harris has become a leading figure in the rational scrutiny of religions and religious cultures, earning himself a place as a prominent “New Atheist,” along with Richard Dawkins, Daniel Dennett, and Christopher Hitchens. To the extent that the New Atheism is a genuine social movement, Harris deserves much of the credit for it. In 2004, he made a dramatic breakthrough when T...

When dealing with a large stratigraphic data set, it is difficult to get a general idea of the excavation’s main features and their chronological sequence because the Harris diagram will become very big. It is hard to understand a diagram consisting of hundreds of equally sized boxes, if no hints are given how to structure them. Large Harris diagrams are seldom published owing to the high costs...

Harris family of distributions models lifetime of a series system when the number of components is a positive random variable. In this paper, we reveal several stochastic comparisons in the Harris family with different tilt parameters and different baseline distributions with respect to the usual stochastic, shifted stochastic, proportional stochastic and shifted proportional stochastic orderin...

Many studies have documented systematic shifts in women’s mate preferences and sexual motivations across the ovulatory cycle. Harris (2012) presents a nonreplication of one particular finding in this literature—namely, that women’s preference for masculinity in men’s faces shifts across the cycle. Harris critiques the empirical and theoretical literature on cycle shifts and concludes that the c...
