The Encyclopedia of Integer Sequences

by N. J. A. Sloane
"... This article gives a brief introduction to the On-Line Encyclopedia of Integer Sequences (or OEIS). The OEIS is a database of nearly 90,000 sequences of integers, arranged lexicographically. The entry for a sequence lists the initial terms (50 to 100, if available), a description, formulae, programs ..."

Exploiting Generative Models in Discriminative Classifiers

by Tommi Jaakkola, David Haussler - In Advances in Neural Information Processing Systems 11 , 1998
"... Generative probability models such as hidden Markov models provide a principled way of treating missing information and dealing with variable length sequences. On the other hand, discriminative methods such as support vector machines enable us to construct flexible decision boundaries and often resu ..."

Highly Dynamic Destination-Sequenced Distance-Vector Routing (DSDV) for Mobile Computers

by Charles E. Perkins, Pravin Bhagwat , 1994
"... An ad-hoc network is the cooperative engagement of a collection of Mobile Hosts without the required intervention of any centralized Access Point. In this paper we present an innovative design for the operation of such ad-hoc networks. The basic idea of the design is to operate each Mobile Host as a ..."

as a specialized router, which periodically advertises its view of the interconnection topology with other Mobile Hosts within the network. This amounts to a new sort of routing protocol. We have investigated modifications to the basic Bellman-Ford routing mechanisms, as specified by RIP [5], to make

SCOP: a structural classification of proteins database for the investigation of sequences and structures.

by Tim J P Hubbard , Bart Ailey , Steven E Brenner , Alexey G Murzin , Cyrus Chothia - J. Mol. Biol. , 1995
"... ABSTRACT The Structural Classification of Proteins (SCOP) database provides a detailed and comprehensive description of the relationships of all known proteins structures. The classification is on hierarchical levels: the first two levels, family and superfamily, describe near and far evolutionary ..."

relationships; the third, fold, describes geometrical relationships. The distinction between evolutionary relationships and those that arise from the physics and chemistry of proteins is a feature that is unique to this database, so far. The database can be used as a source of data to calibrate sequence search

Analysis, Modeling and Generation of Self-Similar VBR Video Traffic

by Mark Garrett, Walter Willinger , 1994
"... We present a detailed statistical analysis of a 2-hour long empirical sample of VBR video. The sample was obtained by applying a simple intraframe video compression code to an action movie. The main findings of our analysis are (1) the tail behavior of the marginal bandwidth distribution can be accu ..."

be accurately described using "heavy-tailed" distributions (e.g., Pareto); (2) the autocorrelation of the VBR video sequence decays hyperbolically (equivalent to long-range dependence) and can be modeled using self-similar processes. We combine our findings in a new (non-Markovian) source model

Gapped BLAST and PSI-BLAST: a new generation of protein database search programs.

by Stephen F Altschul , Thomas L Madden , Alejandro A Schäffer , Jinghui Zhang , Zheng Zhang , Webb Miller , David J Lipman - Nucleic Acids Res. , 1997
"... ABSTRACT The BLAST programs are widely used tools for searching protein and DNA databases for sequence similarities. For protein comparisons, a variety of definitional, algorithmic and statistical refinements described here permits the execution time of the BLAST programs to be decreased substantia ..."

Dynamic taint analysis for automatic detection, analysis, and signature generation of exploits on commodity software

by James Newsome, Dawn Song - In Network and Distributed Systems Security Symposium , 2005
"... Software vulnerabilities have had a devastating effect on the Internet. Worms such as CodeRed and Slammer can compromise hundreds of thousands of hosts within hours or even minutes, and cause millions of dollars of damage [32, 51]. To successfully combat these fast automatic Internet attacks, we nee ..."

Modeling and performance analysis of bittorrentlike peer-to-peer networks

by Dongyu Qiu, R. Srikant - In SIGCOMM , 2004
"... In this paper, we develop simple models to study the performance of BitTorrent, a second generation peerto-peer (P2P) application. We first present a simple fluid model and study the scalability, performance and efficiency of such a file-sharing mechanism. We then consider the built-in incentive mec ..."

Fast and accurate short read alignment with Burrows-Wheeler transform

by Heng Li, Richard Durbin - BIOINFORMATICS, 2009, ADVANCE ACCESS , 2009
"... Motivation: The enormous amount of short reads generated by the new DNA sequencing technologies call for the development of fast and accurate read alignment programs. A first generation of hashtable based methods has been developed, including MAQ, which is accurate, feature rich and fast enough to a ..."

Awareness and Coordination in Shared Workspaces

by Paul Dourish, Victoria Bellotti - Proc. of the Conf. on Computer Supported Cooperative Work (CSCW´92 , 1992

Awareness of individual and group activities is critical to successful collaboration and is commonly supported in CSCW systems by active, information generation mecha-nisms separate from the shared workspace. These mechanisms pena~ise information providers, presuppose rel-evance to the recipient, an ..."
