The isolation failure of cement-formation interface is an important and urgent problem in oil production, while an effective way to solve it is to realize the integrated solidification and cementation of cement-formation interface (ISC-CFI). In order to study the kinetics of ISCCFI with MTA (Mud Cake to Agglomerated Cake) method, the Diamond Differential(More)
Surface non-uniformity of skin tumors is an important hint in the early diagnosis of malignant melanomas in clinic. A virtual contour modeling the surface inhomogeneity is proposed in the paper to evaluating region inhomogeneity of skin tumors. A novel feature cluster, combined irregular and asymmetric descriptors of virtual contour, is formed to describing(More)
