Abstract:
The present invention relates to an energy converting apparatus using liquid and, more specifically, to an apparatus and a method for converting mechanical energy into electric energy by applying the opposition phenomenon to electrowetting. The energy converting apparatus changes a surface in contact with liquid between a pair of electrodes and utilizes the change in the surface in contact with liquid for generating electric energy, so that electrodes complexly patterned on a channel or a lubricating layer are not required or blockage of a channel is prevented. Therefore, the energy converting apparatus can provide less trouble, reduce manufacturing costs, have simplified equipment, make a flexible element, and be easily applied to a large area by simplifying a structure of an element.
Abstract:
According to an embodiment of the present invention, provided is a method for searching a similar string, which is a method for searching a string using a computer, the method comprising: extracting a list of N number of q-grams (where N and q are each an integer of 1 or more) which commonly matches to an input string (σ) and a stored string (s); calculating a lower limit of a string edit distance for the remaining part of the string, excluding the N number of q-grams, among the input string (σ); and selecting the lower limit of the calculated edit distance as the lower limit of the a string edit distance between the input string (σ) and the stored string (s).

Abstract:
PURPOSE: An efficient query processing method and a device thereof are provided to improve search performance by using a partial character string having an unfixed length. CONSTITUTION: A UI(User Interface)(105) receives a query character string and outputs a document including the character string. A database(165) stores information about various documents. A processor(135) generates an effective character string set composed of partial character strings having different lengths through the query character string. The processor determines one of subsets of the effective character string set as a candidate set based on costs of the subsets for accessing the database. The processor searches the database for the document including the query character string by using the candidate set. [Reference numerals] (105) User Interface; (110) Character string set generating unit; (120) Candidate set determining unit; (130) Document searching unit; (140) Index DB; (150) Inverted index DB; (160) Document DB
