... signals and training labels are often contaminated by noise, resulting in globally noisy training data and degraded performance of data-driven models. The purpose of this study is to develop an effective model to improve the accuracy and robustness of bearing fault diagnosis in noisy environments...

...Yanling Wang Purpose The purpose of this paper is to present an imperceptible and robust watermarking algorithm with high embedding capacity for digital images based on discrete wavelet transform (DWT) domain. Design/methodology/approach First, the watermark image is scrambled using chaotic...
