The ground subsidence process induced by underground longwall coal mining is a complicated process of subsidence-induced damage to the ground and the surface buildings. Based on the study of the surface movement and deformation regulation on overburden strata of the mining field, a new predicting analysis of surface movement and deformation is provided based on GIS. By using the method of spatial...
Path planning is basis for any autonomous underwater vehicle to implement completely cruising in subsea environment and path tracking is important technology as well, especially for multi-AUV (Autonomous underwater vehicle) cruising with a fleet formate. In this paper, algorithms path planning and path tracking are addressed for an open frame AUV. Fast Marching algorithm is applied to solve problems...
Finite state machines have the function of reducing the complexity of the robot control system, so it's introduced into the architecture of the excavating robot. For the sake of embodying artificial intelligence and strategy in the state changing of finite state machines, BP neural network is employed in the finite state machines of the excavating robot. Aiming at the slow convergence speed of the...
SoSs (System of Systems) is an unpredictable entity for the users who wish to control and utilize it before it has been constructed. How to distill the concept which is buried in peoplepsilas brain about the SoSs is a difficult and critical work in the SoSs requirement research. This thesis introduce some authority concept of SoSs firstly. By the reference of framework of JCIDS which is USA DOD newly...
