    摘要: A database system comprises an interface for a storage device, and a control device for accessing the storage device through the interface. The storage device stores a table that manages a plurality of rows comprising a plurality of item values, and an index configured in a tree structure based on a plurality of nodes enabling to identify the rows by using one or more item values. The control device identifies an item value condition included in a search condition of a search query, determines whether or not the node of the index corresponding to the item value condition is reference-disabled, and when the node is reference-disabled, identifies a range of item values managed by the reference-disabled node, and searches for a row that satisfies the search condition for the identified range.

    摘要: Provided is a k-nearest neighbor search method of searching for a query number k of nearest points to an arbitrary point in a DBMS for creating a spatial index from multidimensional points, comprising setting a search conditions, judging which of a lowest branch and an intermediate branch of the spatial index a nearest region to the query point is, calculating, when the nearest region is judged to be the lowest branch, a distance between the query point and a child region of the nearest region, storing information of a divided region which has become a calculation target, calculating, when the nearest region is judged to be the intermediate region, a distance between the query point and a point included in the nearest region, storing information of the point which has become a calculation target, finishing search processing when the search conditions are satisfied, and obtaining a search result from the DBMS.

    摘要: A level converter circuit includes a differential amplifier 20 having a load resistor 8 supplied at its one end with a voltage which is stabilized against the variation of a power voltage by an emitter-follower transistor 4 receiving at its base a bias voltage from a bias circuit 9, 12-14. An intermediate signal is derived from the other end of the load resistor and supplied to a level shift circuit 25.
