Abstract: PURPOSE: A method for inserting a higher dimension index structure is provided to enhance a clustering effect in an index structure through an application of a weight center point. CONSTITUTION: In a method for inserting a higher dimension index structure, an object is inserted to a root node when a tree is only composed of the root node.

If a lower node of the root node is a branch node, after inserting an object, branch nodes that the increase of the overlap number with peripheral nodes is less, branch nodes having the same values at many dimensions, branch nodes that the size increase of a minimum bounding region is less, and branch nodes closely adjacent to a center are selected in this order. In case where an overflow occurs at the selected branch node, a reinsertion object is selected in the base on the weight center point so as to be reinserted to the branch node. If an overflow occurs at a branch node at which the reinsertion is performed, the branch node is divided. If an overflow does not occur, the minimum bounding region is adjusted. A terminal node is selected so as to insert an object when the lower node of the root node or of the branch node is the terminal node. A reinsertion object based on the weight center point is selected so as to be inserted to the terminal node when an overflow occurs at the terminal node.

Patent KR-19990028871-A (KR)
IPC: A23K1/00
Filed: 1996-07-22
Abstract: A chemically bonded medium is obtained from a resilient organic macromolecular material, in cut elongate of finely divided form (such as grass or peat). The material is dried (3, 4) under conditions permitting escape of water vapour, such that the dried material has a predominantly hydrophobic surface and a water content of not more than 10 % by weight; and then optionally flashed. The surface properties of the dried material are then equilibrated, under conditions inhibiting escape of water vapour and other volatiles, such that the predominantly hydrophobic surface is rendered predominantly hydrophilic. The product is then mixed (5) with a lignosulfonate, with application of heat in an amount sufficient to maintain the lignosulfonate in fluid form, such that the lignosulfonate forms a coating film on the surface. The lignosulfonate is caused to undergo partial polymerisation (6) (typically by heating and/or treatment with oxygen) on the surface of the dried material to produce a flowable, substantially non-resilient and non-tacky, chemically bonded medium. The bonded medium may be stored or shaped (8) under pressure to form agglomerates.
