Application-layer multicast (ALM) has grown tremendously in recent years, making the distribution of bulk data such as streaming video economically feasible for small companies and even individuals. The efficiency of an ALM network depends on its data distribution overlay, which is constructed based.....

A method of personal identification includes switching between visible and near infrared light, acquiring palmprint image and palm vein image from a person under the visible and the near infrared light, extracting sub-images from the palmprint image and the palm vein image based on a region of inter.....

The wavelength-division-multiplexed passive optical network (WDM-PON) is a promising technology for the next-generation access networks. To realize more flexible network functions, several studies [1-15] have been carried out to simultaneously deliver both point-to-point data and broadcast/multicas.....

Image and video coding standards, such as JPEG, H.264/AVC, are widely used in industry. In these standards, block-based transforms are employed to compact signal energy. The transform coefficients are coarsely quantized. The quantization is the source error that causes coding artifacts, such as bl.....
