Abstract: An eco-friendly power source, such as a battery module for a transportation vehicle includes a first sub-module and a second sub-module each including a plurality of battery cells; a lower cover supporting the first sub-module and the second sub-module; a connection member coupled to the first sub-module and the second sub-module, respectively; and a cooling plate coupled to the lower cover and forming a flow path through which a refrigerant can flow, wherein at least a portion of the flow path is disposed to oppose the connection member with the lower cover interposed therebetween.

Abstract: The system includes a metric map creation unit configured to create a metric map using first image data received from a 3D sensor, an image processing unit configured to recognize an object by creating and classifying a point cloud using second image data received from an RGB camera; a probability-based map production unit configured to create an object location map and a spatial semantic map in a probabilistic expression method using a processing result of the image processing unit, a question creation unit configured to extract a portion of high uncertainty about an object class from a produced map on the basis of entropy and ask a user about the portion, and a map update unit configured to receive a response from the user and update a probability distribution for spatial information according to a change in probability distribution for classification of the object.

Abstract: Disclosed is a composition of a lubricant for cold pilgering of zirconium alloy tubes. More particularly, disclosed is a composition of an external lubricant for cold pilgering of a zirconium alloy cladding tube, the composition exhibiting excellent lubricity and decomposition against microbes.

Abstract: A gap control device for a Pilger die assembly of cold Pilger mills. The gap control device can independently control the height of a pair of bearing blocks which axially support an upper die. A lower plate has first and second receiving holes which respectively correspond to the upper portions of a pair of bearing blocks. First and second wedge plates are fitted into the receiving holes, and respectively have inclined surfaces on the upper portions thereof. First and second adjustment blocks respectively have inclined guide surfaces to be in surface contact with the inclined surfaces of the wedge plates, and are movable horizontally with respect to the lower plate. An upper plate is assembled to the upper portion of the lower plate to cover the adjustment blocks. First and second adjustment bolts allow the first and second adjustment blocks to be respectively manipulated in a horizontal direction.
