Abstract: Method of producing aromatic hydrocarbons including: supplying a raw material stream to a C6 separation column, supplying an upper discharge stream from the C6 separation column to a first gasoline hydrogenation unit, and supplying a lower discharge stream from the C6 separation column to a C7 separation column; supplying an upper discharge stream from the C7 separation column to a hydrodealkylation reaction unit and supplying a lower discharge stream from the C7 separation column to a C8 separation column; separating benzene from discharged streams from the first gasoline hydrogenation unit and the hydrodealkylation reaction unit; removing a lower discharge stream from the C8 separation column and supplying an upper discharge stream from the C8 separation column to a second extractive distillation column; and separating styrene from a lower discharge stream of the second extractive distillation column and separating xylene from an upper discharge stream of the second extractive distillation column.

Abstract: Provided are a method for generating a summary and a system therefor. The method according to some embodiments may include calculating a likelihood loss for a summary model using a first text sample and a first summary sentence corresponding to the first text sample, calculating an unlikelihood loss for the summary model using a second text sample and the first summary sentence, the second text sample being a negative sample generated from the first text sample, and updating the summary model based on the likelihood loss and the unlikelihood loss.

Abstract: The present invention relates to a light detecting and ranging (LiDAR) device for obtaining information on a distance from an object using laser light.

Abstract: A light detection and ranging (lidar) device includes: a lower base; an upper base; a laser emitting unit for emitting a laser in a form of a point light source; a nodding mirror for transforming the laser in the form of the point light source to a line beam pattern which is perpendicular to the lower base, wherein the nodding mirror reflects the laser emitted from the laser emitting unit; a polygonal mirror for transforming the line beam pattern to a plane beam pattern and receiving a laser reflected from an object; and a sensor unit for receiving the laser reflected from the object via the polygonal mirror.

Abstract: A display device includes a pixel. The pixel is electrically connected to a first power line, a second power line, and a data line. The pixel includes a first transistor, and a capacitor electrically connected between a gate electrode of the first transistor and an electrode of the first transistor. In a plan view, the data line extends in a second direction. The first power line extends in a first direction intersecting the second direction and overlaps the data line and the gate electrode of the first transistor. The second power line extends in the second direction, overlaps the data line, and overlaps the gate electrode of the first transistor.

Abstract: An electronic device is provided. The electronic device includes an electronic component connected to a Printed Circuit Board (PCB), a housing comprising a recess configured to accommodate the electronic component and a hole formed in at least part of the recess to pass the PCB, and a sealing member disposed in at least part of the hole and configured to cover at least part of the PCB.

Abstract: A portable terminal including a body, a front deco positioned along a periphery of the body, a main battery cover positioned on a rear surface of the body to cover a battery, and a waterproofing cover interchangeable with the front deco and the main battery cover so that when substituted for the main battery cover and front deco all water intrusion paths on the portable terminal are sealed.
