In order to fulfill the practical application demands of precisely localizing underwater vehicles using passive electric field localization technology, we propose a scalar-potential-based method for vehicles. This is grounded on an intelligent differential evolution algorithm and particularly suited use in three-layer stratified oceanic environments. Firstly, based potential distribution law constant current elements parallel ocean environment, mathematical positioning model established...
In order to predict the rock rupture and instability, acoustic emission signals of natural sandstones hydrous are analyzed through Fast Fourier Transform Welch method.It is found that have narrower range frequency spectrum lower average dominant frequencies than sandstones.The reduce more dramatically.In addition, two types power in terms shape presented this paper, which named Type A B. The B emerges when occurs frequently, a disaster tends appear.Time baselines selected relative stronger...
