Jaderin wires (base apparatus) An apparatus used for base line measurement. It consists of separate steel and brass wires, extended under constant tension over reference tripods in the line of the base. The coefficients of expansion and lengths at a certain temperature of the two wires having been found, the temperatures of the wires themselves may be deduced from the difference of the measurement of the same distance by the two wires. With these temperatures known, the length of the base may be accurately obtained. HDBK-850

Joint Photographic Experts Group (JPEG) JPEG is a standardized image compression mechanism. JPEG is designed for compressing either full-color or gray-scale images of natural, real-world scenes. JPEG handles only still images, but there is a related standard called Motion Pictures Expert Group (MPEG) for motion pictures. JPEG is "lossy," meaning that the decompressed image isn't quite the same as the one you started with. JPEG is designed to exploit known limitations of the human eye, notably the fact that small color changes are perceived less accurately than small changes in brightness. Thus, JPEG is intended for compressing images that will be looked at by humans. [Note 1: JPEG is also the name of the ISO standards body for still imagery compression standards.] OSU-CIS Web Site
