    Optimal vibration image size determination for convolutional neural network based fluid-film rotor-bearing system diagnosis

    This paper suggests an image gradient based method that determines the optimal image size for convolutional neural network (CNN)-based diagnosis of fluid-film rotorbearing systems. As distinct patterns improve...

    Effect of deposition temperature on the formation of defect phases in BiFeO3 thin films

    We report the effects of deposition temperature on the evolution of defect and second phases and on the ferroelectric properties of BiFeO3 thin films. We grew BiFeO3 thin films on (001) SrTiO3 substrates by using...
