Abstract: A vehicle battery control apparatus which includes a memory and a controller. For example, the vehicle battery control apparatus obtains at least one of driving durability data according to a driving state of a host vehicle or calendar aging data according to a parking state of the host vehicle, or any combination thereof, obtains degradation data of a battery of the host vehicle using at least some of the driving durability data or the calendar aging data, or the any combination thereof, and compares reference data identified based on a predetermined reference model with the degradation data to determine a degradation state of the battery.

Abstract: This disclosure describes a system and method for effectively training a machine learning model to identify features in DAS and/or seismic imaging data with limited or no human labels. This is accomplished using a masked autoencoder (MAE) network that is trained in multiple stages. The first stage is a self-supervised learning (SSL) stage where the model is generically trained to predict data that has been removed (masked) from an original dataset. The second stage involves performing additional predictive training on a second dataset that is specific to a particular geographic region, or specific to a certain set of desired features. The model is fine-tuned using labeled data in order to develop feature extraction capabilities.

Abstract: A method for forming a line and a space pattern, according to one embodiment of the present invention, comprises exposing a mask in a first direction and a second direction on a substrate and stitching same. The method for forming a line and a space pattern comprises the steps of: performing first exposure on the substrate so that first shots of the mask come in contact with each other in the first direction; and performing second exposure on the substrate so that second shots of the mask come in contact with each other so as to be distanced in the second direction and be offset with respect to the first shots in the first direction.

Abstract: A grid voltage stabilization system according to an embodiment of the present invention comprises: a power generation device for generating power by using a new and renewable energy source, and supplying the generated power to a grid; an energy storage system (ESS) for, according to a command value, storing power generated in the power generation device in a battery, or supplying power stored in the battery to the grid in the form of active power and reactive power; and a power management system (PMS) for, when a voltage value of the grid is out of a reference range, controlling the magnitude of the reactive power to be supplied to the grid such that the command value is changed according to the voltage value of the grid to enable the voltage of the grid to be within the reference range.
