The vertical security problem of maglev train is challenging for nonlinearity, external disturbances, unmeasurable airgap velocity and constrained output. To solve this problem, a semi-supervised ...

We demonstrate an oscillatory behavior of resonant wavelengths and threshold gains of the fundamental and first-order transverse mode of photonic crystal vertical-cavity surface-emitting laser (PhC ...

Trucks have been unable to meet vertical clearance requirements on major roads for various reasons, leading to accidents. CTAP met with the Department of Transportation (DOTr) and Secretary Vince ...
