Abstract: An aerial survey plane having a cover for protecting a lens of an infrared camera for an aerial survey according to an exemplary embodiment of the present invention includes: an aerial survey observation window; an aerial survey infrared camera; at least one shock absorbing part to absorb shock applied to the aerial survey infrared camera; at least one support vertically provided on the shock absorbing part; a lifting part to lift and lower the aerial survey infrared camera; a protective cover provided between the aerial survey infrared camera and the bottom surface of the fuselage of the aerial survey plane and having a size to cover the aerial survey observation window; at least one motor to move the protective cover toward any one direction; and a controller to remotely control the opening and the closing of the protective cover.

Abstract: The present inventions generally relate to a leaf node ranking method in decision trees for spatial prediction and its recording medium. The leaf node ranking method in decision trees includes a learning step to form a decision tree having one root node, in which each parent node has multiple child nodes, using training data sets for spatial prediction; and a leaf node ranking step from the decision tree that finishes the learning. In the learning step, each node of the decision tree stores both the number of classes according to class distribution of training data and structures for storing the number. In the leaf node ranking step, a rank of a leaf node is determined using the number of classes according to class distribution, which is stored in each node on a path from the root node to the leaf node.

Abstract: Disclosed is an apparatus for monitoring hot waste water discharged from a power plant by using an airborne multispectral scanner system. The apparatus includes a first detector including a first image data collecting unit to obtain first image data and a liquid-phase nitrogen storing tank used to cool an image obtaining sensor, a second detector including a second image data collecting unit to obtain second image data, and a liquid-phase nitrogen storing tank used to cool an image obtaining sensor, a controller to process the first and second image data obtained by the first detector and the second detector, respectively, and an auxiliary liquid-phase nitrogen tank separated from the liquid-phase nitrogen storing tank. The auxiliary liquid-phase nitrogen tank complements liquid-phase nitrogen for cooling.
