Abstract: An occupant safety system using an optical fiber grid sheet and a method thereof are provided. The occupant safety system applies light to optical fibers constituting an optical fiber grid which is attached to a moving body and in which the optical fibers are arranged in a grid pattern; receives the applied light through the optical fibers; grasps a location of impact on the moving body based on the received light receiving signals; and controls operations of safety devices provided in the moving body based on the grasped location of the impact. Accordingly, the occupant safety system can sense impacts on the moving body everywhere through the optical fiber grid, and can exactly grasp the location of the impact and can drive an appropriate safety device timely. Therefore, the occupant can be protected safely.

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: Proposed is a digital twin system for digitizing technologies related to development of perovskite solar cells, performing design, test, simulation, and verification on materials, physical/chemical properties, and structures in a virtual environment, and designing and manufacturing an optimal perovskite solar cell. The digital twin system may provide a digital twin system for, when developing perovskite solar cells, identifying the efficiency of solar cells without directly conducting experiments, and through simulation of various environments using various learning/inference models, optimally designing perovskite-based solar cells. Also proposed is a digital twin system that is designed with a machine learning operations (MLOps) structure to have a configuration in which initially designed learning/inference models are updated to resemble the real environment as the learning/inference models undergo experiments, enabling testing in a more realistic virtual environment.

Abstract: Proposed is a container-based high availability big data framework system. The system may include an external server configured to provide structured data. The system may also include a data collection server constructed based on a docker container environment and configured to collect structured data by requesting the structured data from the external server at a predetermined time interval. The system may further include a monitoring server configured to execute a new docker image by generating a trigger when detecting the occurrence of an error while the structured data are collected.
