The issue of class imbalance has been well-studied in the multi-class classification framework, but its exploration within multi-dimensional classification (MDC) has been somewhat overlooked due to the complexity of the imbalance shift phenomenon. This occurs when a sample is categorized as belonging to both a minor and a major class, depending on the labeling dimension.

On April 24, automated guided vehicles moved the Ariane 6 central core, which includes the main and upper stages, at a speed of 3 km/h from the launcher assembly building to the launch pad 800 meters away.
The central core's placement on the launch pad involved coordinated actions using two AGVs and a crane equipped with a lifting beam. This allowed for the upright positioning of the centr

Every part of a launch vehicle, launch pad, and ground operation equipment is subjected to the high acoustic load generated during lift-off. Therefore, many extreme measures are taken to try to suppress this acoustic environment by damping with a water deluge system and diverting engine plumes away from the vehicle via flame trenches. Even single decibel reductions of the acoustic levels can tra
