Axlebox bearing is one of the key components of train bogie. The condition of the axlebox bearing has great influence on rail traffic security. A real time and effective axlebox bearing fault diagnosis method could avoid traffic accidents and reduce operation costs. By this way, we can adopt condition-based maintenance instead of preventive maintenance which

The machine learning is divided into learning supervision, unsupervised learning and semi-supervised learning according to whether priori information was used or not and the proportion of priori information used in reduced-rank methods. In allusion to shortcomings of unsupervised learning, for example that initial value is strongly depended on, input parameters are needed in advance and

With the increasing improvement on functions of missiles, satellites and other large systems, requirements of reliability for the systems are also increasing. Electronic equipments are the core control units of large systems, so requirements of reliability for them are strict. Analog circuits take a small proportion of electronic circuits, but they are easier to go
