Grey-level sequence images are analyzed from the point of view of strange attractors. Multifractal feature maps are used to extract the features from the video sequence image. The nonuniform property of the image is reflected in the singularity spectrum and the Mandelbrot spectrum. Each video-object plane (VOP) specifies a particular image sequence content and the textures in the different contents can be separated because similar textures generally will have an homogeneous property which can be characterized by the singularity and Mandelbrot dimension of the fractal sets. Consequently, we can achieve not only image segmentation, but also a separation of the video-object layers (VOLs).","PeriodicalId":177613,"journal":{"name":"Conference Proceedings.

Each algorithm in this class first transforms the original data to be compressed into an irreducible table representation and then uses an arithmetic code to compress the irreducible table representation. From the irreducible table representation, one can fully reconstruct the original data by performing multistage parallel substitution. A set of rules is described on how to perform hierarchical transformations from the original data to irreducible table representations. Theoretically, it is proved that all these algorithms outperform any finite state sequential compression algorithm and hence achieve the ultimate compression rate for any stationary and ergodic source. Furthermore, experiments on several standard images show that even a simple algorithm in this class, the so-called multi-level pattern matching algorithm, outperforms the Lempel-Ziv algorithms and arithmetic codes.","PeriodicalId":177613,"journal":{"name":"Conference Proceedings.

The boron diffusivity is four times lower than that in Si implanted with the same dose of B and annealed under identical conditions. TEM studies and SIMS results confirm the presence of extended defects in the surface region, end-of-range (EOR) defective region beyond the amorphous/crystalline interface (X/sub a/c/), and threading dislocations in between. The retardation is partially due to the trapping of B atoms and/or self-interstitials by extended defects remaining after the solid phase epitaxy. Future work is required if the dominant cause is to be determined.","PeriodicalId":177613,"journal":{"name":"Conference Proceedings.

As an alternative to studying individual programmers, we examine the group productivity of programmer teams. We postulate that there is such a thing as average programmer productivity, in a given context. By studying programmer teams, we can eventually obtain measures of the expected performance of an average programmer in a defined context. Differences in project productivity can then be attributed to process characteristics. Existing project data is examined to see how data could be collected to support the idea of a standard programmer.","PeriodicalId":177613,"journal":{"name":"Conference Proceedings.

One of the major features of PNN stems from its modular architecture design and can be easily extended to adapt to a changing environment by incremental learning. Another distinguishing advantage of PNN comes from its fast training speed as compared to backpropagation. An explicit confidence measure can also be obtained which directly supports the decision made by the PNN. Preliminary experimental classification results of various AC power system faults and transients indicate that the PNN is suitable for power line fault classification.","PeriodicalId":177613,"journal":{"name":"Conference Proceedings.
