  • Publication number: 20060190425
    Abstract: Systems and methods for conducting attribute-based queries over a plurality of objects using bounded memory locations and minimizing costly input and output operations are provided. A plurality of attributes are associated with each object, and a plurality of data groups, one each for the identified attributes are created. The objects associated with the attributes are placed into the appropriate data groups, and the objects contained within each data group are sorted into blocks such that each block within a given attribute contains that objects having the same attribute value. Results to the query are created by loading blocks into a primary memory location in a middleware system and combining the loaded blocks to create the desire query results. Block combinations are created based upon the fit of the given block combination to the query as expressed in an aggregation function.

  • Publication number: 20060161559
    Abstract: Methods and systems for analyzing XML documents. The system scans an XML document, identifies different dimensions that span the XML document and detects scoping relationships amongst them. The system uses the dimensional information to create a logical hierarchical scoped dimension analysis model, maps the logical XML tree to this model, and then implements the analytical method over the logical model. The logical model allows both structural features and numeric/non-numeric data to be used for analysis. The analytical method allows users to query irregular structural properties of the XML documents using the XPath navigational API.

  • Publication number: 20060161525
    Abstract: The introduction of extensions to query processing systems for XML documents that allow the analysis of such documents via grouping and aggregation operations. Assumed is the existence of an analysis module for extracting information on how parts of an XML document interrelate with other parts. This information is then used together with a user query in order (1) to partition the nodes of the document in various ways and (2) to compute and output the aggregation value of each such partition. To these ends, there are provided new query operators and extensions to query processing systems comprising a hierarchical node list generator and a hierarchical node list processor. The former takes the grouping information from the query as input and generates document node partitionings. The latter takes the node partitionings as input and computes aggregation values for each partition and generates a query result that is returned to the user.

  • Publication number: 20060003326
    Abstract: The present invention relates to a modified L-nucleic acid, comprising a L-nucleic acid part and a non-L-nucleic acid part, whereby the L-nucleic acid part is conjugated to the non-L-nucleic acid part and the conjugation of the L-nucleic acid part with the non-L-nucleic acid past leads to a slowed elimination out of the organism, in comparison with a L-nucleic acid which only comprises the L-nucleic acid part, said L-nucleic acid part being a spiegelmer.

  • Publication number: 20050190206
    Abstract: Disclosed is a method for determining a pixel gray scale value image, particularly for a multi-dimensional image system. According to said method a first modulation signal (M1) which is emitted at the emitting end and is reflected on an object that is to be recorded is correlated with a second modulation signal (M2) and is recorded at the receiving end based on at least two correlation signals (Ua, Ub or Ia, Ib) that are proportional to the respective received first modulation signal (M1). One of said modulation signals (M1, M2) is phase shifted in several phase steps (?k) at the emitting or receiving end and a differential signal (D) is determined for each phase step (?k) based on the correlation signals (Ua, Ub or Ia, Ib,) and a pixel gray scale value (PGray) is determined based on said difference signal (D) independently of interfering signals.

  • Publication number: 20050114758
    Abstract: Improved document annotation techniques are provided. For example, in one aspect of the invention, a technique for determining an annotation for a document includes the following steps/operations. A user-proposed annotation to be associated with the document is obtained. Then, the technique automatically determines, in accordance with a knowledge base, whether the user-proposed annotation matches at least one allowed annotation.

  • Publication number: 20050050016
    Abstract: A method of utilizing one or more hints for query processing over a hierarchical tagged data structure having a plurality of nodes in a computing system having memory, the hint being positive if there is a tag accessible in top-down traversal from a child node, and otherwise negative. For each tag in the data structure, the method calculates a bitmap for a current node with all bits set to 1 and for each child node, followed by AND-ing all child bitmaps and setting a bit corresponding to a tag ID of a current tag to zero if such current tag exists. The method further sets a bit of a current tag to 0, calculates a plurality of possible non-redundant hints for each child node, and refreshes a hint list.

  • Publication number: 20040176532
    Abstract: A process of producing a graft polymer of the ABS type by the emulsion method is disclosed. In the process wherein 5 to 95% by weight of a monomer mixture that contains A) 50 to 99 parts by weight of at least one vinyl aromatic compound and B) 1 to 50 parts by weight of at least one copolymer is polymerized in the presence of C) 95 to 5% by weight of one or more graft substrates having a glass transition temperature <10° C., the improvement includes monitoring continuously in the course of the reaction the Raman spectra of the reaction mixture, determining deviations from the specified desired course of the reaction and making corresponding adjustments.
