This paper presents the Gavagai Living Lexicon, which is an online distributional semantic model currently available in 20 different languages. We describe the underlying distributional semantic model, and how we have solved some of the challenges in applying such a model to large amounts of streaming data. We also describe the architecture of our implementation, and discuss how we deal with co...

In this report we present the first experimental results to support our proposal [1] as an attempt to optimize stream processing for XML data. A core prototype called O-Search was implemented to have a concrete understanding for the complexity of stream-querying algorithms i, with respect to different structures of XML documents (wide, depth, various size). Space and time measurements are appli...

We propose a new, media-independent protocol for including program timing, structure and identity information in Internet media streams. The protocol uses signaling messages called cues to indicate events whose timing is significant to receivers, such as the start or stop time of a media program. We describe the implementation and operation of a prototype Internet radio station which transmits ...

the influence of leachate from open solid waste dumping near salhad stream (abbottabad, pakistan) was investigated to quantify the variations of water quality during august 2007 to april 2008. samples were collected from five different sites located along the salhad stream. two sites were located before the mixing of solid waste leachate with the surface water. one sampling site was of leach...

Binary Decision Diagram (in short BDD) is an efficient data structure which has been used widely in computer science and engineering. BDD-based attack in key stream cryptanalysis is one of the best forms of attack in its category. In this paper, we propose a new key stream attack which is based on ZDD(Zero-suppressed BDD). We show how a ZDD-based key stream attack is more efficient in time and ...

Stream ciphers are vulnerable to generic time-memory-data tradeoff attacks. These attacks reduce the security level half of cipher’s internal state size. The conventional way handle this vulnerability is design cipher with an twice as large desired level. In lightweight cryptography and heavily resource constrained devices, a size big drawback for cipher. This principle can be found in eSTREAM ...

Some extensions of the basic formalism of stream processing functions are useful to specify complex structures such as operating systems In this paper we give the foundations of higher order stream process ing functions These are functions which send and accept not only messages representing atomic data but also complex elements such as functions Some special notations are introduced for the sp...

A new family of very fast stream ciphers called COS (for “crossing over system”) has been proposed by Filiol and Fontaine, and seems to have been adopted for at least one commercial standard. In this note we show that the COS ciphers are very weak indeed — it requires negligible effort to reconstruct the state of the keystream generator from a very small amount of known keystream.
