In recent years, new semistatic word-based byte-oriented text compressors, such as Tagged Huffman and those based on Dense Codes, have shown that it is possible to perform fast d...
In this paper the performance limits and design principles of rateless codes over fading channels are studied. The diversity-multiplexing tradeoff (DMT) is used to analyze the syst...

In this paper, we present a multi-label sparse coding
framework for feature extraction and classification within
the context of automatic image annotation. First, each image

—We present the design and implementation of UDAE, a Universal Data Access Engine for wireless sensor networks. The UDAE allows developers to access data both locally and over th...
The problem of securing a network coding communication system against a wiretapper adversary is considered. The network implements linear network coding to deliver n packets from s...
