Graph learning often boils down to uncovering the hidden structure of data, which has been applied in various fields such as biology, sociology, and environmental studies. However, distributed sensing ...

It is difficult to achieve long measurement range with high precision in displacement measurement, a new nanometer displacement sensor, named time grating, is proposed to tackle this problem. The ...

Considering that the number of fracture elements at time t is M, based on the fundamental solution of displacement discontinuity, the displacement generated by each element can be calculated.
