Abstract: The present disclosure relates to a method and system for producing refined hydrocarbons from waste plastic pyrolysis oil. The method and system for producing refined hydrocarbons from waste plastic pyrolysis oil according to the embodiments of the present disclosure may minimize formation of an ammonium salt (NH4Cl) and may prevent an adhesion phenomenon of impurity particles in a reactor in a refining process of waste plastic pyrolysis oil containing impurities including chlorine and nitrogen. In addition, the method and system for producing refined hydrocarbons according to the embodiments of the present disclosure may have excellent refining efficiency and may implement a long-term operation of a process because deactivation of a catalyst used in the process is prevented, and may produce refined hydrocarbons having a low content of impurities and a low content of olefins from waste plastic pyrolysis oil.

Abstract: One aspect of the present disclosure provides a method for automatically removing a background sound source of audio data of a video, including separating the audio data including at least one sound source component into a first component related to a human voice and a second component related to sounds other than the human voice using a first separation model, separating the first component into a vocal component and a speech component using a second separation model, separating the second component into a music component and a noise component using a third separation model, and generating an audio data with the background sound source for the audio data of the video removed by synthesizing the speech component and the noise component.

Abstract: Disclosed are a parking operation control apparatus and a control method thereof. The apparatus includes a first sensing unit to sense current wheel speed of an automobile in a parking release mode or a current front-wheel speed of the automobile in a parking operation mode, a first controller to receive the current wheel speed and output the same and to store a reference wheel-speed range, a second sensing unit to sense the current wheel speed from the first controller, a first judgment unit to judge whether the current wheel speed deviates from the reference wheel-speed range, or whether the current wheel speed sensed by the second sensing unit is not output, and a regulation unit to regulate the current wheel speed to conform to the reference wheel-speed range when the first judgment unit judges that the current wheel speed deviates from the reference wheel-speed range or is not output.

Abstract: An apparatus and method for manufacturing a steel tube are provided. The apparatus includes: a tube-forming device for forming a steel plate into a steel tube; a heat treatment device connected in-line to the tube-forming device to heat the steel tube to a high temperature; a pre-treatment device for annealing the steel tube and providing a reduction atmosphere; and a plating device including a pot for storing a SeAHLume alloy composed of aluminum and zinc in a molten state, a level block selectively inserted into the molten alloy to adjust a level of the molten alloy, and a plating part into which the molten alloy flows in response to insertion of the level block and through which the steel tube passes substantially vertically. Therefore, it is possible to manufacture a steel tube having a plated surface to improve its corrosion-resistance.

Abstract: A post-editing apparatus for correcting translation errors, includes: a translation error search unit for estimating translation errors using an error-specific language model suitable for a type of error desired to be estimated from translation result obtained using a translation system, and determining an order of correction of the translation errors; and a corrected word candidate generator for sequentially generating error-corrected word candidates for respective estimated translation errors on a basis of analysis of an original text of the translation system. The post-editing apparatus further includes a corrected word selector for selecting a final corrected word from among the error-corrected word candidates by using the error-specific language model suitable for the type of error desired to be corrected, and incorporating the final corrected word in the translation result, thus correcting the translation errors.
