  • We present a syntactically enriched vector model that supports the computation of contextualized semantic representations in a quasi compositional fashion. It employs a systematic combination of first- and second-order context vectors. We apply our model to two different tasks and show that (i) it substantially outperforms previous work on a paraphrase ranking task, and (ii) achieves promising results on a wordsense similarity task; to our knowledge, it is the first time that an unsupervised method has been applied to this task. ...

  • Security has become a major concern for every network administrator. Nearly every day we are bombarded with news articles describing yet another high-profile company that has fallen prey to a network-based attack. To fill in the occasional gap, we hear about new viruses that have been found “in the wild” or about additional software vulnerabilities that someone has figured out how to exploit for personal gain. The network security field has not always been this crazy. Most of us can remember a time when securing a network environment was a far easier task.

  • As science has become more interdisciplinary and impinges ever more heavily on technology, we have been led to the conclusion that there is a great need now for a textbook that emphasizes the physical and chemical origins of the properties of solids while at the same time focusing on the technologically important materials that are being developed and used by scientists and engineers.

  • During the preparation of this book, we found that almost all the textbooks on signal analysis have a section devoted to the Fourier transform theory. The Fourier transform is a mathematical operation with many applications in physics, and engineering that express a mathematical function of time as a function of frequency, known as its frequency spectrum; Fourier's theorem guarantees that this can always be done.

  • Visual compression has been a very active field of research and development for over 20 years, leading to many different compression systems and to the definition of international standards. There is likely to be a continued need for better compression efficiency, as video content becomes increasingly ubiquitous and places unprecedented pressure on upcoming new applications in the future. At the same time, the challenge of handling ever more diverse content coded in a wide variety of formats makes reconfigurable coding a potentially useful prospect....

  • EXPONENTIAL STABILITY OF DYNAMIC EQUATIONS ON TIME SCALES ALLAN C. PETERSON AND YOUSSEF N. RAFFOUL Received 6 July 2004 and in revised form 16 December 2004 We investigate the exponential stability of the zero solution to a system of dynamic equations on time scales. We do this by defining appropriate Lyapunov-type functions and then formulate certain inequalities on these functions. Several examples are given. 1. Introduction This paper considers the exponential stability of the zero solution of the first-order vector dynamic equation x∆ = f (t,x), t ≥ 0. (1.
