The hybrid system shows its ability of measuring temperature, strain and vibration along a 9-kilometer long single mode fiber, with a favorable measurement accuracy.

The l₂ normalized inverse, shifted inverse, and Rayleigh quotient iterations are classic algorithms for approximating an eigenvector of a symmetric matrix. This work establishes rigorously that each ...
