For solving problems encountered in the PHP course, MOOC Embedded Flipped Classroom Model is proposed in this paper, which will make up for the shortage of the existing course. The basic model is ...

The step-stress model is becoming quite popular for analyzing lifetime data obtained from accelerated life testing experiments. In the usual step-stress experiment, stress levels are allowed to change ...

"The simple mechanical model we propose here, a viscoelastic toy model, provides a novel scenario to explain the static friction paradox in stick-slip instability without artificial friction laws," ...
