Integrated architectures for learning, planning, and reacting based on approximating dynamic programming

by Richard S. Sutton - Proceedings of the SevenLh International Conference on Machine Learning , 1990
"... gutton~gte.com Dyna is an AI architecture that integrates learning, planning, and reactive execution. Learning methods are used in Dyna both for compiling planning results and for updating a model of the effects of the agent's actions on the world. Planning is incremental and can use the probab ..."

SURF: Speeded Up Robust Features

by Herbert Bay, Tinne Tuytelaars, Luc Van Gool - ECCV
"... Abstract. In this paper, we present a novel scale- and rotation-invariant interest point detector and descriptor, coined SURF (Speeded Up Ro-bust Features). It approximates or even outperforms previously proposed schemes with respect to repeatability, distinctiveness, and robustness, yet can be comp ..."

be computed and compared much faster. This is achieved by relying on integral images for image convolutions; by building on the strengths of the leading existing detectors and descrip-tors (in casu, using a Hessian matrix-based measure for the detector, and a distribution-based descriptor); and by simplifying

Adaptive clustering for mobile wireless networks

by Chunhung Richard Lin, Mario Gerla - IEEE Journal on Selected Areas in Communications , 1997
"... This paper describes a self-organizing, multihop, mobile radio network, which relies on a code division access scheme for multimedia support. In the proposed network architecture, nodes are organized into nonoverlapping clusters. The clusters are independently controlled and are dynamically reconfig ..."

Tor: The secondgeneration onion router,”

by Roger Dingledine - in 13th USENIX Security Symposium. Usenix, , 2004
"... Abstract We present Tor, a circuit-based low-latency anonymous communication service. This second-generation Onion Routing system addresses limitations in the original design by adding perfect forward secrecy, congestion control, directory servers, integrity checking, configurable exit policies, an ..."

In vivo gene delivery and stable transduction of nondividing cells by a lentiviral vector

by Luigi Naldini, Ulrike Blomer, Daniel Ory, Richard Mulligan, Fred H. Gage, Inder M. Verma, Didier Trono - Science , 1996
"... A retroviral vector system based on the human immunodeficiency virus (HIV) was de-veloped that, in contrast to a murine leukemia virus-based counterpart, transduced heterologous sequences into HeLa cells and rat fibroblasts blocked in the cell cycle, as well as into human primary macrophages. Additi ..."

have often relied on vectors derived from retro-viruses such as murine leukemia virus (MLV) (1, 2). These vectors are useful because the genes they transduce are inte-grated into the genome of the target cells, a desirable feature for long-term expression. However, these retroviral vectors can only

PHENIX: a comprehensive Python-based system for macromolecular structure solution

by Paul D. Adams, B Pavel V, Vincent B. Chen, D Ian W, Jeffrey J. Headd, D Li-wei Hung, Gary J. Kapral, D Ralf W. Grosse, A Airlie J. Mccoy, Nigel W. Moriarty, A Robert, Y J. Read, David C. Richardson, D Jane S, D Thomas C, Terwilliger E, Peter H. Zwart A - Acta Crystallogr. D Biol. Crystallogr , 2010
"... Macromolecular X-ray crystallography is routinely applied to understand biological processes at a molecular level. However, significant time and effort are still required to solve and complete many of these structures because of the need for manual interpretation of complex numerical data using many ..."

many software packages and the repeated use of interactive threedimensional graphics. PHENIX has been developed to provide a comprehensive system for macromolecular crystallographic structure solution with an emphasis on the automation of all procedures. This has relied on the development of algorithms

A classification of schema-based matching approaches

by Pavel Shvaiko - JOURNAL ON DATA SEMANTICS , 2005
"... Schema/ontology matching is a critical problem in many application domains, such as, semantic web, schema/ontology integration, data warehouses, e-commerce, catalog matching, etc. Many diverse solutions to the matching problem have been proposed so far. In this paper we present a taxonomy of schema- ..."

Emerging Frameworks for Tangible User Interfaces

by Brygg Ullmer, Hiroshi Ishii , 2001

Adaptive Duplicate Detection Using Learnable String Similarity Measures

by Mikhail Bilenko, Raymond J. Mooney - In Proceedings of the Ninth ACM SIGKDD International Conference on Knowledge Discovery and Data Mining (KDD-2003 , 2003

A Query Language for XML

by Alin Deutsch, Mary Fernandez, Daniela Florescu, Alon Levy, Dan Suciu , 1998
"... An important application of XML is the interchange of electronic data (EDI) between multiple data sources on the Web. As XML data proliferates on the Web, applications will need to integrate and aggregate data from multiple source and clean and transform data to facilitate exchange. Data extraction, ..."

, conversion, transformation, and integration are all well-understood database problems, and their solutions rely on a query language. We present a query language for XML, called XML-QL, which we argue is suitable for performing the above tasks. XML-QL is a declarative, "relational complete" query
