Traveling-wave starting algorithm based on morphological gradient and wavelet transform modulus sum

On the basis of basic morphological transforms and their combined modes,transient current signals can be extracted by use of morphological gradient with adaptive weighting.

This paper presents a novel algorithm of identifying the inrush current and short circuit current caused by internal fault on the basis of transient detection using morphological gradient, meanwhile transient current signals are extracted by use of morphological opening and closing algorithm.

Then edge detection based on morphological grads provides better license plate s edge and is propitious to locate exactly.

Based on the comprehensive analyses of stratigraphic temperature measurements in the Haila′er Basin,this paper investigates the present geothermal gradient and heat flow of different units,the controlling factors of the present geothermal field and its function in forming oil and gas.

Combined with the vitrinite reflectance ( R o) depth relationship calculated by the chemical kinetic model of vitrinite evolution, the theoretical maturity thresholds ( R o) for oil preservation under different geothermal gradient co.
