A novel method to stretch light pulses is proposed by using the free-space coupling technique,with which the ultrashort laser pulses can excite ultrahigh-order modes in the symmetrical metal-cladding optical waveguide with sub-millimeter scale.

Vulnerability forecasting model based on coupling technique of GIS and ANN in floor groundwater bursting;

So the authors have established an evaluation model for mine structural complexity based on coupling technique of non-linear ANN and Mapobjects with spatial analytical function.

Present situation and development of supercritical fluid coupling technology;

The coupling technology of super-luminescent laser diode (SLD) to single mode panda-type polarization maintained optical fiber was investigated using Gaussian mode approximation and mode field matching.

Using combination technology, the sample of the main control parameter is changed to a genetic sample.

In order to solve the problem,the DOF coupling method was used to simulate the mechanical characteristics of ball bearing between the vehicle body and its turret.
