Abstract: Provided are road object recognition method and apparatus using a stereo camera, and the road object recognition method using a stereo camera includes a road image acquisition step of acquiring a road image by using the stereo camera, a road surface recognition and separation step of recognizing a road surface from the acquired road image and separating the road surface, and a road object recognition step of recognizing a road object from the separated road surface. According to the road object recognition method and apparatus using the stereo camera, in a state in which a front traveling vehicle is included, a road surface is recognized from a road image acquired using the stereo camera and is separated, so that it is possible to effectively recognize objects on the recognized road surface.

Abstract: Disclosed are an additive for suppressing electrochemical migration (ECM) in an electrical wire, and a method of inhibiting the ECM using the additive. A solution containing the ECM-inhibiting additive may inhibit creation of dendrite to prolong an ECM time. The additive as proposed may be mixed with polymer materials such as epoxy molding compound (EMC) or underfill materials used for packaging a semiconductor, or the like. Alternatively, the additive as proposed may be added to metal electrical wires to improve the reliability of semiconductor devices.

Abstract: The present disclosure provides an aluminum alloy with enhanced penetration resistance for a heat exchanger, the alloy containing copper (Cu), silicon (Si), and iron (Fe) equal to or smaller than predetermined contents respectively, and further containing zirconium (Zr) and the remainder being aluminum (Al). Further, the present disclosure provides an aluminum extruded tube and/or an aluminum fin with enhanced penetration resistance made of the alloy respectively. Further, the present disclosure provides a heat exchanger comprising the tube and/or fin. Addition and content-control of the alloy element may spread corrosion initiations and suppress intergranular corrosion to create uniform corrosion. In this manner, the present alloy have superior corrosion resistance compared to pitting corrosion of a previous alloy for a heat exchanger, and, at the same time, have an extrusion rate equal to that of the previous A1070.
