In order to investigate the relationships among the expanded extrusion capacity of continuous extrusion for copper bus bar and the billet diameter,friction condition and structure parameters of chamber and die,the expanded deformation zone of billet was divided into two sub-zones according to the deformation characteristics of billet in the expanded die chamber.

Based on the biomechanics theory,the anomalous 3D middle layer was deformed using extended free form deformation technology.

Manufacturing semisolid A2017 alloy by srs process and semisolid extending forming;

Numerical simulation of continuous extrusion extending forming for copper bus-bar based on finite volume method;

Contrast analysis of extending forming between continuous extrusion and forward extrusion

Automatic target recognition often utilizes the cont ra st between the target and surrounding clutter, but extended fractal utilizes not only the contrast but also shape of target.

The extended fractal (EF) feature is a detection statistic, which can greatly enhance the detection probability.

The conventional target detections in SAR images such as VAR method, constant false alarm rate algorithm and extended fractal method were introduced.
