With the growth of broadband networks, Video-on-Demand (VoD) has become realistic. Many significant broadcasting schemes have been proposed to reduce the bandwidth requirement for stored popular videos. One representative approach is the Staircase Broadcasting (SB) scheme. In comparison with other schemes, the SB scheme requires smaller disk buffer and disk transfer rate. However, the scheme cannot be used for provide reliable delivery over lossy channels perfectly. In this paper, we proposed an Interleaving Staircase Broadcasting (ISB) scheme, which guarantees continuous playback, and mitigates the effect of packet losses. Some bounds on the bandwidth consumption, the buffer requirements, and the required disk transfer rate are also developed. Further, in comparison with the Interleaving Harmonic Broadcasting (IHB) scheme, Interleaving Cautions Harmonic Broadcasting (ICHB) scheme, Reliable Periodic Broadcasting (RPB) scheme and Second Chance Broadcasting (SCB) scheme, the ISB outperforms on maximum buffer requirements, and maximum required disk transfer rate. The IHB scheme consumes the least bandwidth.

We consider the problem of LSB matching detection in grayscale images which is hard and hot in steganalysis. In this paper, we model the matching embedding as a kind of image degradation caused by some certain pulse additive noise, and use the restored image by wavelet denoising as an estimation of the cover image. The detectors we used are the 1D and 2D adjacency histogram characteristic function center of mass introduced in the literature [8]. We extract the features of the image before and after estimation and classify the cover and stego images with support vector machine. Experimental results show that our method is superior to Ker's calibrated estimation method, especially in low false positive probability.
The collective motion of a set of moving entities like people, birds, or other animals, is characterized by groups arising, merging, splitting, and ending. Given the trajectories of these entities, we define and model...

With the growth of broadband networks, Video-on-Demand (VoD) has become realistic. Many significant broadcasting schemes have been proposed to reduce the bandwidth requirement for stored popular videos, but they cannot be used for provide reliable delivery over lossy channels perfectly. Herein, we propose a new broadcasting scheme, called the Interleaving Harmonic Broadcasting (IHB) scheme, which guarantees continuous playback, and mitigates the effect of packet losses. Further, in comparison with the Poly-Harmonic Broadcasting (PUB), Cautions Harmonic Broadcasting (CUB) scheme, Reliable Periodic Broadcasting (RPB) scheme and Second Chance Broadcasting (SCB) scheme, the IHB outperforms on required bandwidth, maximum required buffers and maximum disk transfer rate.

It is commonly accepted that time is a critical issue in news recommendation. As opposed to book or movie recommendations, news articles have extremely short life spans and should normally not be recommended after a few days. Most current news recommender systems use time as a decaying factor in ratings or just cut off older articles according to some simple mechanism. An experiment done on four different newspapers in Norway reveal that the time issue is somewhat more complicated. The life span of articles varies substantially from one newspaper to another, and from one category to another. Social media like Facebook may affect articles' life span, though the influence of social media is highly category-dep.ndent.
