In this paper, a neural network scheme is presented for modeling VBR MPEG-2 video sources. In particular, three non linear autoregressive models (NAR) are proposed to model the aggregate MPEG-2 video sequence, each of which corresponds to one of the three types of frames (I, P and B frames). Then, the optimal mean-squared error predictor of the NAR model is implemented using a feedforward neura...

Biologists require genetic as well as molecular tools to decipher genomic information and ultimately to understand gene function. The Berkeley Drosophila Genome Project is addressing these needs with a massive gene disruption project that uses individual, genetically engineered P transposable elements to target open reading frames throughout the Drosophila genome. DNA flanking the insertions is...

object detection plays an important role in successfulness of a wide range ofapplications that involve images as input data. in this paper we have presented anew approach for background modeling by nonconsecutive frames differencing.direction and velocity of moving objects have been extracted in order to get anappropriate sequence of frames to perform frame subtraction. stationary parts ofbackg...

The ‘frames of reference’ concept has been a significant and enduring feature industrial/employment relations since being developed by Alan Fox; yet there only limited scholarly research seeking to develop the frames. We introduce this special issue reviewing extant literature on frames which provides backdrop five article contributions that explore in both new historical light. issues ask foll...

In this paper, we statistically characterized four VBR encoded video sequences, containing I/B/P frames, at the Slice layer with the goal of developing an accurate source model to better understand the bit-rate behavior of these sources. We presented the cells/slice distributions and showed that it is “heavy tailed” and fits the Pareto distribution better than Gamma. We showed that an 8-state M...

In this paper, an algorithmic architecture of video compression at very low bit rate is presented. This architecture incorporates block-based as well as segment-based coding algorithms and manages them in a cooperative way in which different approaches are applied to different image frames iteratively: I and P frames are coded by block-based algorithm and 0 frames are coded by segment-based alg...

zipper braced frames are an innovative bracing system for steel structures. conventional inverted-v-braced frames exhibit a design problem arising from the unbalanced vertical force generated by the lower story braces when one of them buckles. this adverse effect can be mitigated by adding zipper columns or vertical members connecting the intersection points of the braces above the first floor....
