    Abstract: Proposed is an artificial intelligence (AI) model-based analysis method for an optimal design of a secondary battery electrolyte. The AI model-based analysis method may include obtaining a tomography image of a calendared battery material, and inputting the tomography image to a pre-trained AI model. The method may also include outputting a viscosity and a transmittance of a battery electrolyte through the AI model. The AI model may include a first AI model configured to analyze porosity distribution and tortuosity information about the tomography image input thereto. The AI model may also include a second AI model configured to output a viscosity and a transmittance corresponding to the electrolyte, based on the porosity distribution and tortuosity information.

    Abstract: Provided are a method and a system for generating a human animation from SMPL series parameters. An animation generation method according to an embodiment includes: extracting, by a motion extraction module, motion information from an image content; converting, by a motion conversion module, the extracted motion information into parameters required by an animation generation module; and generating, by the animation generation module, a motion image of a human object from the converted motion information. Accordingly, an animation accurately showing motions of an object appearing in an image content by a more realistic 3D model may be generated and digital human contents of high reality may be created and used.

    Abstract: A method of generating a predictive model is proposed. The method may include receiving single time-series data or multiple types of time-series data collected in a specific domain, drawing time-series data corresponding to the same domain and time interval, among the received single time-series data or multiple types of time-series data. The method may also include pre-processing the drawn time-series data by applying a pre-processing pipeline built by applying at least one pre-processing module to the drawn time-series data, and generating a pattern classification model for classifying patterns of the pre-processed time-series data based on the clustering of the pre-processed time-series data. The method may further include generating a predictive model for predicting feature information of the drawn time-series data based on a cluster that is generated as the results of the clustering of the pre-processed time-series data, and storing the pattern classification model and the predictive model.

    Abstract: A continuous hologram recording method is provided. A holographic printer according to an embodiment of the present invention comprises: a light source that emits light; a modulator that modulates the light emitted from the light source, to generate a holographic fringe pattern in units of hogels; a stage having placed thereon a hologram recording medium on which a holographic fringe pattern generated by the modulator is to be recorded in units of hogels; a first driving unit that moves the position of the stage in a first axial direction by using a first-type motor; and a second driving unit that moves the position of the stage in a second axial direction by using a second-type motor different from the first type. Accordingly, continuous hologram recording is enabled by appropriately implementing a motor that moves the stage on which the hologram recording medium is placed, according to vibration characteristics, thereby remarkably reducing the printing time for large holograms, which used to take several days to tens of days, and thus accelerating the commercialization of hologram printing.

    Abstract: There is provided an ultra-small size broadband coupler. A Lange coupler according to an embodiment includes: first lines which are formed in a spiral shape, and have a first port and a second port formed at one end thereof and have connection ends formed at the other end thereof; and second lines which are formed in a spiral shape, and have connection ends formed at one end thereof to be connected to the connection ends of the first lines, and have a third port and a fourth port formed at the other end thereof. Accordingly, the Lange coupler maintains broadband characteristics while minimizing its area, so that it is possible to design a small component for mobile communication and to noticeably reduce an insertion loss.

    Abstract: A method and a system for foveated hologram rendering are provided. A method for foveated hologram rendering according to an embodiment of the present invention comprises: tracking a user's line of sight, rendering a hologram having a first resolution in the user's central line of sight, and rendering a hologram having a resolution lower than the first resolution in the user's peripheral line of sight. Accordingly, a hologram content with high quality and high resolution can be generated and reproduced at high speed through foveated hologram rendering in which holograms having different resolutions are rendered in the user's central line of sight and peripheral line of sight.
