The method may be performed by a stealth clock follower device and may include transmitting a sync message received from a neighbor device to an end-follower device, receiving a delay-request message from the end-follower device, and updating a residence time in a correction field of the received delay-request message. The method may also include transmitting the updated delay-request message to a leader device, receiving a delay-response message from the leader device, and performing time synchronization based on a time of the leader device by using an ingress time of the sync message, an egress time of the updated delay-request message, and time information contained in the sync message and the delay response-message. The method may further include transmitting the delay-response message to the end-follower device for time-synchronization.

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: A 3D spatial scanning system and method can perform accurate 3D spatial scanning in various environments. The 3D spatial scanning system may include a sensor group, a confidence estimator, a function adjuster, and a fusion part. The sensor group may scan space using a time-of-flight (ToF) sensor and a stereo red-green-blue (RGB) sensor included therein. The confidence estimator may fuse a sensing value of the ToF sensor and a sensing value of the stereo RGB sensor and estimate a confidence of the sensing values. The function adjuster may adjust a function of at least one of the ToF sensor and the stereo RGB sensor based on the confidence estimated by the confidence estimator. The fusion part may fuse the sensing value of the ToF sensor and the sensing value of the stereo RGB sensor based on function adjustment of the function adjuster.

Abstract: There is provided an emotion prediction method based on virtual facial expression image augmentation. The emotion prediction method may acquire a user facial image, may extract a facial expression feature from the acquired user facial image, and may predict a user emotion from the extracted facial expression feature. The emotion prediction method may extract the facial expression feature by using a facial expression recognition network, the facial expression recognition network being an AI model that is trained to receive a user facial image and to extract a facial expression feature. The facial expression recognition network is retrained with virtual facial images which are augmented from a facial image that causes a failure in emotion recognition. Accordingly, by augmenting features of a facial expression image that causes a failure in prediction through error feedback, facial expression recognition performance can be enhanced.
