Application of wavelet-neural network in defect location non-destructive testing of MDF;

Defect location,representative defect and its ultrasonic echo characteristics corresponding of tungsten alloy shells had been systematically studied by both vertical wave sensors and transverse wave sensors calibrated after manufacturing.

This paper introduces the method to the defect location in the scarf welding joint by ultrasonic test,which can be adopted in the construction site.

Fault localization is the key to detect and eliminate the faults.

A new method of the precise location to ships is proposed, which used an antenna sensor array in this paper.

To solve this problem, a new method for template detection and location under complex background is provided in this paper, which consists of two steps, template detection and precise location.

This paper emphasizes some important points in the process of geological map mapping using AutoCAD,such as coordinates correspondence transformation means,precise location method,the application of blocks,the using of hatch tool in geological section maps and defining patterns,etc.

Precise Positioning and Control of the CNC Chain Magazine;

Application of geophysical method to the precise positioning of urban seismic mobile moving fault;

The special setting for precise positioning of the X-ray source in industrial Computed Tomography(ICT) system has been made,and the testing program has been developed.
