A mobile terminal comprises a body comprising a keypad and a slider slidingly coupled to the body. The slider is configured to slide transversely with respect to the body and may comprise a display unit to display image information. The mobile terminal may further comprise a processor coupled to the slider to detect when the slider is slid from a first position to a second position and when the slider is slid from a second position to a first position. The image information may be rotated 90 degrees from a transverse orientation to a longitudinal orientation when the processor detects that the slider has been slid from the first position to the second position. Conversely, the image information may be rotated 90 degrees from a longitudinal orientation to a transverse orientation when the processor detects that the slider has been slid from the second position to the first position.

A method and an apparatus search an image using a feature point. The image search method extracts at least one feature point from an image and describes the extracted at least one feature point in stages, thereby generating a hierarchical feature point descriptor. In addition, the method may search for information matching the feature point descriptor from a local database (DB) included in a terminal or a remote DB included in a server.

Disclosed are a document ranking system and method based on contribution scoring. The document ranking system includes: a content score calculating unit for calculating content scores for documents with respect to at least one word contained in the documents, with regard to each such word; a contribution score calculating unit for calculating contribution scores for the documents with respect to jointly occurring words; and a ranking unit for ranking the documents with respect to the at least one word, with regard to each such word, by using the content scores and the contribution scores.

摘要:
Disclosed are a rotor for generating vortex water flow that creates shear intensity for removing solid material adhered to the separation membranes during the processing of water containing pollutant material, and a filtering apparatus employing the same. The rotor consists of a first rotor having first blades and a second rotor having second blades. The first and the second blades are extended in a radial direction from a rotational axis thereof, and are disposed at positions different from each other in the rotational axis direction. The first blades and the second blades have widths different from each other in a circumferential direction around the rotational axis, or disposed at positions different from each other in a circumferential direction. Protrusions can be attached on outer surfaces of the first blades and/or second blades. The pollutant material adhered to the separation membrane can be removed effectively since various types of vortex water flow are generated over wide range, and the energy loss of the filtering apparatus is reduced.

A frame structure for stage erection comprises a plurality of support frames and a bridge. The support frames are disposed parallel to each other, and respectively have rail recesses formed in the length direction in facing locations. The bridge connects across the support frames so as to maintain a mutually parallel state, and has a rail-joining part for fastening to and separating from the rail recesses in at least one of the two end locations.
