The authors analyze four MPEG-1 VBR encoded high quality, color video sequences. None of the sequences contain audio.

They show the distributions given by each of the models and show their fit to the gamma and Pareto distributions using the QQ plot.","PeriodicalId":334874,"journal":{"name":"Proceedings IEEE Southeastcon '95.

Instead, control variables are represented by fuzzy variables which let the level of uncertainty of the variables be modeled in a systematic way. In addition the expert knowledge of a typical operator of such a process is embodied in a set of linguistic or rule-based engines which constitutes the core of a fuzzy controller. The magical advantages of fuzzy controllers over the classical ones have been demonstrated by recent results in diverse application domains as well as the surge of commercial products to worldwide consumer market. Thus, the control engineering research, education, and practice have to be revised accordingly. Fortunately, this area finally found its long-expected place in academia and industry, after its first introduction about thirty years ago. Recently, there have emerged many fuzzy logic software and hardware products. The objective in this paper is to give a comparative review of these resources and techniques, and introduce the reader to the state of knowledge in fuzzy controller design research and education. Subjects such as fuzzy set theory, fuzzy logic, fuzzy ruled based expert systems, intelligent control, and fuzzy control will be studied. A number of case studies and applications of fuzzy controls, and some fuzzy logic hardware and software tools are pointed out.","PeriodicalId":334874,"journal":{"name":"Proceedings IEEE Southeastcon '95.

Normalized cross-correlation is used to locate feature points which are common to both 2D images. The displacements of these feature points are used to generate disparity maps, and disparity values can be used to compute x,y,z locations. Since disparity maps are typically noisy and not fully populated with known disparity points, a mathematical curve fitting is necessary to fill in missing points and smooth the data. Adaptive smoothing algorithms have been investigated and used to develop a method for refining the disparity map and reconstructing 3D surfaces.","PeriodicalId":334874,"journal":{"name":"Proceedings IEEE Southeastcon '95.

In modern times, with computer communications being practical, Internet offers an interconnecting medium for data, information, and file transfer. In addition, services and tools are being continuously added to the Internet and the network operation is being constantly upgraded and made more and more reliable. Internet has been steadily expanding not only in academic and research circles, but also in the industrial and commercial areas. For example, it is a simple matter of conversing with another user on the Internet for immediate exchange of information in banking and other financial operations. In addition, considerable effort is being spent to make the Internet more interactive for integrated voice and data services. From a system point of view Internet provides end to end digital connectivity. Also, being a driven network at the higher layers, Internet tends to be more fault than the original architecture. The advances in Internet, and associated applications are summarised.","PeriodicalId":334874,"journal":{"name":"Proceedings IEEE Southeastcon '95.

However, the triangle function does not exhibit the proper edge behavior for surface current and charge at a conducting knife-edge. The proper edge behavior is incorporated into the basis function set via a minor modification. The effect of the modified basis set on the computation of the axial electric field in the aperture of open-ended bodies of revolution is considered. Both straight and tapered cylinders are investigated. The convergence properties of the edge-modified triangle basis set are found to be superior to those of the normal triangle basis function set.","PeriodicalId":334874,"journal":{"name":"Proceedings IEEE Southeastcon '95.
