18) Focused on a posteriori error estimates a finite volume discretization of an elliptic problem.

19) In the second chapter, we present an additive Schwarz preconditioner for the rotated Q_1 finite element discretization of second order elliptic problem.

20) Attributes in the database of tumor diagnoses are usually quantitative attributes[sentencedict.com], so quantitative attribute discretization is a problem of mining association rules.

21) By introducing the concept of"nihility point"and the method of"spherule bounding" in the algorithm, we have simply and effectively realized boundary discretization in 3-D space.
