Abstract: An automatic train operation assistance device includes a data extraction unit that acquires operation data including the operation of a train and load factors of the vehicles of the train from a data collection device that collects equipment data on the train, a feature extraction unit that extracts, using the operation data, operation data on an inter-station including a travel time taken by the train to travel from a first station to a second station and a stoppage time for which the train is stopped at the first station or the second station, as features, and an operation prediction unit that constructs a prediction model using the features, and predicts the future operating conditions of the train including the future position of the train, using the prediction model and current features.

Abstract: A method for gain control for an optical amplifier module is provided. The method may include receiving an input light signal at a first amplifier. The method may include dynamically adjusting a gain of the input light signal based on feedback monitoring of an output light signal. The method may include receiving the gain adjusted light signal at a second amplifier for output of the optical amplifier module.
