Steatotic liver disease often progresses asymptomatically, with the risk of advancing to cirrhosis and liver cancer. Early ...

To solve this problem, this article presents a damage index (DI) construction method based on the Kullback-Leibler (KL) divergence of the normal time-frequency distribution covariance matrix. This ...

A research team led by Dr. Takehito Seki, Lecturer at the Institute of Engineering Innovation, School of Engineering, the University of Tokyo, achieved direct measurement of nanometer-scale charge ...

Increasing penetration of inverter-based generators (IBG) in distribution systems is raising concerns on system strengths such as over-voltages, abnormal fault levels and frequency excursions. The ...

IN the evaluation of experimental data it is not unusual to find frequency distribution curves resulting from the overlap of two or more normal components.
