In the aeronautical industry, there are multiple diagnosis methods available to improve the accuracy in diagnosing malfunctions due to degradation of rotating components in an engine. This study introduces an improved deep learning algorithm — ad_DBN, it is based on the Deep belief network (DBN) method, mimics the multilayer structure of a human brain. In addition to this, it adjusts connection weights...
Role-based access control strategy has been widely applied to a variety of access control system. Permission checks are employed in this strategy to improve flexibility and easier management, using dynamic proxy to optimize the process. Facilitating an authority through permission checks helps provide grained transaction management safely. In this study we proposed an authority control method based...
We propose a new decision model for sub-health in this paper. Unlike traditional statistical analysis method, the model is built with rough sets and BP neural network with 18743 items of data owning 155 dimensions of attributes, we divide sub-health state into three different grade at first in order to reflect the precision of the model. The results of experiments show that the precision of judgment...
