disadvantage factor
1.It has been demonstrated that VEGF-C and VEGF-D is related to lymphangiogenesis of UCC and the subsequent formation of pelvic lymph node metastases,in which VEGF-C is a disadvantage prognostic factor of UCC.
2.Because the algorithm can adjust the rectification factor of fuzzy controller with the Least Means Squares (LMS) method, it not only can reflect the advantage of ruzzy logic in nonlinear system but also can improve the disadvantage of common fuzzy control method which is strongly dependent on human experiences.
3.Based on the automatic weld tracking system of submerged arc welding which takes the direct-arc-typed sensor,aiming at the disadvantage of low accuracy which exists in the traditional deviation checking method with welding current,a new arc signal processing method and control strategy—currentvoltage dual control examining method—was put forward,and a simulating model was build up by MATLAB to study the influence of the adjustment factor under difference circumstances on the examination results.
