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: Proposed is a positive electrode containing a positive electrode active material having a multimodal particle-size distribution to suppress particle crack of the positive electrode active material caused by pressure applied during a positive electrode and cell manufacturing process, thereby exhibiting excellent electrical characteristics. In addition, an all-solid-state battery including the positive electrode is proposed. The positive electrode may include a positive electrode active material formed of a lithium transition metal oxide and having a multimodal particle-size distribution in which particles with relatively small particle diameters have greater particle strength than particles with relatively large particle diameters.

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: A patch based depth mapping method and apparatus for high-efficiency encoding/decoding of a plenoptic video is proposed. The method may be performed in an electronic apparatus to classify a reference image and an additional image from a plenoptic video during encoding the plenoptic video and then generate an atlas including a patch using the additional image. The method may include mapping a depth value by applying minimum-maximum linear scaling in units of an input viewpoint image. The method may also include finding a minimum value and a maximum value of the depth value per the patch and remapping the depth value through minimum-maximum linear scaling.

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.

Abstract: A system for foreign object detection (FOD) in wireless power transfer is proposed. The system may include a balanced coil which is disposed between a transmitter coil and a receiver coil and which includes a Maxwell bridge circuit. The system may also include a temperature sensor configured to measure a temperature of the transmitter coil. The system may further include a processor configured to determine whether an FO is present between the transmitter coil and the receiver coil on the basis of voltage values detected at both ends of the bridge circuit. The FOD system can recognize the FO by finding a maximum resonant frequency at which a metal reacts using resonant frequency sweeping in a bridge circuit.

Abstract: This application relates to an apparatus and method for providing a wrap-around view based on three-dimensional (3D) distance information. The apparatus may include a camera module, a sensor module, and a controller. The camera module acquires image information in all directions, and the sensor module measures 3D spatial information in all directions. The controller is configured to generate 3D distance information by projecting the measured 3D spatial information onto a two-dimensional (2D) plane, to generate a 3D model in a 3D space by using the generated 3D distance information, and to generate a wrap-around view by mapping the acquired image information to the generated 3D model.

Abstract: Proposed is an apparatus, system, and method for conducting a company-customized work evaluation of employees based on work sincerity and work concentration to induce employees toward the ideal talent pursued by the company. The apparatus may receive an input of setting values for work sincerity and work concentration each including a plurality of evaluation items, setting values for weights for the respective evaluation items, and setting values for satisfaction/violation conditions from a manager terminal. Additionally, the apparatus may receive data on work sincerity and work concentration obtained by collecting and counting event information on satisfaction/violation for each evaluation item according to an employee's work from a plurality of employee terminals. Also, the apparatus may perform work evaluation on a plurality of employees via a work evaluation algorithm that uses the work sincerity and work concentration data and the weights as input values.
