Abstract: Disclosed herein are a catalyst for hydrocracking reaction of high molecular weight components in bio-oil, a method for preparing the same and a method for bio-oil upgrading using the same. The catalyst includes a zeolite carrier; and at least one metal selected from the group consisting of nickel (Ni), ruthenium (Ru) and cerium (Ce) supported on the carrier. The catalyst promotes the hydrocracking of high molecular weight compounds contained in the bio-oil, but also inhibits the polymerization reaction of the decomposed product, thereby more effectively enhancing the hydrocracking reaction of the bio-oil.

Abstract: A smart anchor-based position estimation method and apparatus are disclosed. The position estimation method, performed by a position estimation apparatus, includes: identifying one or more line-of-sight (LOS) anchors from among one or more anchors mounted in a vehicle; selecting reference anchors from among the one or more LOS anchors; and estimating a position of a tag based on a number of the reference anchors. The reference anchors are selected based on a rate of formation of an ultra-wideband (UWB) link to the tag and accuracy of the estimated position of the tag.

Abstract: Provided is a jetting driver that can be used for various types of heads with minimal changes. The jetting driver includes: an image board receiving raw image data and generating image data by transforming the raw image data into a form suitable for a type of heads used; and an interface board physically separated from the image board, receiving the image data, and transmitting the image data to the heads through a plurality of channels.

Abstract: Disclosed in the present invention is a floating hologram system. The floating hologram system includes a diffuser configured to form a projection image using light beams transmitted from an image transmitter and diffuse the formed image, and a holographic optical element on which the image diffused from the diffuser is incident and which generates a virtual image floating at a position a predetermined distance therefrom and has a convex lens characteristic. A distance between the diffuser and the holographic optical element is determined based on a focal length of the holographic optical element and a distance from the holographic optical element to the virtual image.
