    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (635 KB) | HTML iconHTML

    In this paper, analysis and simulations of splitting and merging self-similar traffic are done on a router/switch which uses prioritized VOQs (Virtual Output Queue) as its input queues and crossbar as its switch fabric. The results of the simulations say that merge traffic with the same Hurst values (no matter what the data rate is) will not change the Hurst value of merged traffic, but merge traf...

    Real-time segmentation of moving objects in video sequences is a fundamental step for surveillance systems. One of successful methods for complex background is to use a multicolor background model per pixel. However, Common problem for this approach is that it suffers from illumination changing environment, in addition, it is incapable of removing shadows of moving objects. This paper proposed an ...

    The formation relative motion control by using one body fixed thruster and reaction wheels is a challenging problem due to the coupled translational and rotational dynamics. As the thruster vector depends on the current attitude and its angular velocity, and some of the attitude constraints also couple the position and attitude of the spacecraft, it makes the formation control problem high dimensi...

    For many applications like video surveillance and digital cinema, it is desirable to encode video content with constant video quality. However, although constant quantization parameter is used in video encoder, quality fluctuation in macroblock level is still very large and standard deviation of PSNR is typically about 1.8 dB. Since distortion is introduced in the process of quantization of DCT co... View full abstract»

    In computer graphics, animated models have been widely used to represent time-varying data. Reducing the models complexly is a common way to overcome the rendering limitations. In this paper, we propose an efficient method for generating multiresolution animated models based on deformation distance analysis. Our method obtains different LOD models by performing iterative edge contraction operation... View full abstract»

    Future network intruders are constantly changing, improving and extending the capabilities of their botnets. Peer to peer bots are now under widespread development and are quickly evolving into a much tougher species to kill. However, partly due to the lack of understanding of the structural potential of command and control mechanism a botnets can have, countering peer to peer botnets has been ine... View full abstract»
