摘要:
This disclosure is directed to techniques for aggregating marine weather radar data and sea state sensor data from ships or other sea-based data collecting nodes, potentially also with non-sea-based data collecting nodes. In one example, a system is configured to receive, via a remote coverage broadband datalink system, one or more sets of marine environmental condition data from one or more sea-based data collecting nodes. The system is further configured to aggregate the one or more sets of marine environmental condition data from the one or more sea-based data collecting nodes into one or more aggregated sets of marine environmental condition data. The system is further configured to output at least one of the aggregated sets of marine environmental condition data to one or more recipient systems.

Techniques for providing information describing how users are funneling through various products and features of a website are described. According to various embodiments, a user specification of a first set of one or more entities is received. A data structure storing a plurality of data structure entities is then accessed, each of the data structure entities corresponding to an online user session and describing one or more user interaction events included in the corresponding online user session. A set of the plurality of data structure entities are then retrieved from the data structure, the set of the plurality of data structure entities corresponding to online user sessions that include a user interaction event with at least one of the entities in the first set. Information regarding the retrieved set of the plurality of data structure entities is then provided to a user, via a user interface.

A method, apparatus and computer program product for navigating in a multi-dimensional space containing an electronic publication formed from predefined portions of text-based data encoded using a markup language are disclosed. A selected predefined portion is displayed in a first display region. A point on a primary axis of the multi-dimensional space corresponding to the displayed pre-defined portion is also displayed. Also, a method, apparatus and computer program product for publishing an electronic publication formed from predefined portions of text-based data encoded using a markup language are also disclosed. Predefined portions are stored in terminal nodes. Higher level nodes are provided for organising the terminal nodes into an hierarchical structure embodied in said electronic publication. Each higher level node contains the identity of a parent node, a position indicator for the higher level node and an associated identifier.

A storage section stores positional information and a physical amount for each of a plurality of physical amount set points arranged in a three-dimensional model. A division section generates division data corresponding to each of a plurality of second regions obtained by dividing a first region including the three-dimensional model so as to make the number of physical amount set points included in each second region equal. When a position in the three-dimensional model is designated, a search section acquires from the storage section a physical amount for a physical amount set point corresponding to the designated position of physical amount set points which division data corresponding to a second region, of the plurality of second regions, including the designated position includes.

A virtual table index mechanism and a method for a multi-attribute compound condition query relate to a field of computer application technology. The virtual table index mechanism for a multi-attribute compound condition query includes: an index manager; a condition analyzer; and a pre-execution engine. The present invention forms index key values corresponding to a plurality of attributes in a virtual table. When querying, a query condition for the virtual table is calculated. Referring to a key value index, whether a mapping physical table of the virtual table should be executed is independently pre judged according to the attributes, so as to ensure that query is applied only to a virtual sub-table satisfying a corresponding key value condition. The present invention is effective for multi-attribute compound condition query, and is suitable for indexing virtual tables.
摘要:
Enlargement values indicating a degree of enlargement when spatial data is stored in a partial spatial region are calculated for one or more partial spatial regions within a multidimensional index, and in the case where the enlargement value is greater than or equal to a threshold value, a new partial spatial region that contains at least the spatial data is generated.

This invention discloses a novel method for storing data in virtual multidimensional blocks and accessing and retrieving desired information from these blocks. Specific items of data whose characteristics fall within the range of a specified block are stored within that block. Blocks with smaller ranges are nested within larger blocks with the same characteristics. This invention's search method involves checking the specific range of a search query against the largest relevant block range, and then successively checking smaller and smaller range blocks that contain the desired data. This method provides greater speed and accuracy than conventional database linear storage and record by record search methods.

A computer memory for storing an n-dimensional object for access by an application program being executed on a data processing system comprising a data structure stored in the memory including information about the n-dimensional object used by the application program and including a first pitch selector node including a plurality of first pitch selector branches, each of the first pitch selector branches representing a pitch.
摘要:
A method of identifying objects intersecting a search window comprises (i) searching each structure associated with each element of a pitch selector; (ii) for each of the structures, searching all subspaces that intersect the search window; and (iii) within each of the subspaces, identifying objects intersecting the search window.
