Iris recognition becomes an important technology in our society. Visual patterns of human iris provide rich texture information for personal identification. However, it is greatly challenging to match intra-class iris images with large variations in unconstrained environments because of noises, illumination variation, heterogeneity and so on. To track(More)
For the solution of insufficient test data and single information can not represent all the fault state in the analog circuit fault diagnosis, a fault diagnosis model and a fusion algorithm based on data fusion technology is formed. The fault diagnosis information is fused with two layers: For the feature layer, the voltage and current of testing nodes are(More)
Maintenance problems of deteriorateing systems have been studied in the past several decades. Since most systems after maintenance are somewhere between as good as new and as bad as old, this paper developed Kijima’s virtual age model to describe the imperfect preventive maintenance. A new improvement factor was proposed to evaluate the age(More)
