Digital twin (DT) is emerging as a key technology for smart manufacturing. The high fidelity DT model of the physical assets can produce system performance data that close to reality, which provides remarkable opportunities machine fault diagnosis when measured condition are insufficient. This paper presents an intelligent framework machinery based on and deep transfer learning. First, built by...

The traditional deep learning-based bearing fault diagnosis approaches assume that the training and test data follow same distribution. This assumption, however, is not always true for collected in practical scenarios, leading to significant decline performance. In order satisfy this transfer learning concept introduced by transferring knowledge learned from other or models. Due excellent capab...

The characteristics of near-fault ground motion are investigated considering heterogeneous slip distribution on the fault plane. Areas on the fault plane with large slip in compare with the average slip on the fault are known as asperity. The characteristics of strong ground motions in near-fault area are strongly affected by faulting parameters such as asperity location, maximum slip of asperi...

Surface movement and deformation with fault differ significantly from that without fault. To explore the mechanism of abnormal surface subsidence induced by instability, mechanical model for slip soil cantilever were separately established when mining in hanging wall footwall. Moreover, based on numerical similarity simulation experiment, difficulty instability was compared analysed. The result...

Inter-turn fault (ITF), a typical motor fault, results in significant variations the thermal characteristics of motor. For temperature rise (TR) experiments and field-stress field simulations an induction are carried out to reveal related ITF. First, based on actual structure cooling type motor, whole-domain simulation model was established. The reasonable equivalence calculation heat transfer ...

Changes in the physical landscape of SE Raasay at end last Quaternary glaciation are examined. The area is marked by a major fault system defining Beinn na Leac Fault Block, and field survey shows this to comprise rollover anticline SW, with extensional movement towards NE along an oblique transfer fault, Main Fault. was reactivated after Last Glacial Maximum. Survey distinctive ridge detached ...

This article proposes a method to decentralize the navigation burden and improve fault tolerance for spacecraft constellation. The constellation body reference system is introduced, which perifocal frame of one satellite in structure proposed constructed enable each estimate its own orbit this system. step essentially relative determination (OD) based on inter-satellite range measurements. Ther...
