Under continuous braking and long slope braking conditions of high intensity for a long time, the temperature of the brake friction plate is extremely high, which leads to poor braking efficiency in the braking process, and even makes the braking for

In navigation of autonomous underwater vehicles (AUVs), the estimation of position is an important issue, especially, when the sensors such as gyroscopes contain a lot of noise, and the velocity information of Doppler velocity log (DVL) is affected b

At present, the core of lidar data registration algorithms depends on search correspondence, which has become the core factor limiting the performance of this kind of algorithm. For point-based algorithms, the data coincidence rate is too low, and fo
