    Abstract: An underground power cable having an optical fiber sensor for measuring temperature distribution is disclosed. In the power cable, an optical fiber for measuring temperature distribution is received in a stainless steel tube having excellent strength, and this optical tube is interposed between a core and a sheath of the power cable. When arranging the optical tube in the power cable, a supporting material having a relatively low strength than the optical tube is arranged in the cable together in order to prevent the optical fiber from being damaged by external force and prevent the inner insulation layer from being broken down by the optical tube. In addition, a fixing tape for fixing the optical tube in contact with the core may be added to prevent the optical tube from being bent seriously or inclined to one side when the cable is bent.

    Abstract: Provided is a method for magnifying an image by interpolation. The method including: a) setting m×m local windows and calculating a direction of each m×m local window; b) when a linear direction exists in an m×m local window, considering an edge exists; c) when a linear direction does not exist in the m×m local window, dividing the m×m local window into m/2×m/2 sub windows and calculating directions of the m/2×m/2 sub windows; d) when the directions of the m/2×m/2 sub windows exists toward the center of the m×m local window, considering a corner exists in the m×m local window; and e) selecting pixels located in a virtual line that goes along in the linear direction or in the directions to calculate a new pixel value by using the pixels.
