The consistent tanh expansion(CTE) method is employed to the(2+1)-dimensional Caudrey–Dodd–Gibbon–Kotera–Sawada(CDGKS) equation. The interaction solutions between solitons and the cnoidal periodic waves are explicitly obtained. Concretely, we discuss a special kind of interaction solution in the form of tanh functions and Jacobian elliptic functions in both analytical and graphical ways. The results show that the profiles of the soliton-cnoidal periodic wave interaction solutions can be designed by choosing different values of wave parameters.

In this paper, a new preconditioner for numerical solutions of symmetric indefinite linear systems is presented. The new preconditioner called as product preconditioner is constructed through the product of two fairly simple preconditioners. The eigenvalues distribution and the form of the eigenvectors of the product preconditioned matrix are analyzed. Numerical experiments illustrate the effectiveness of product preconditioner.

Lithium-ion batteries(Li Bs) have seen increasing use in automobiles and buildings over the past decade. Usable lifetimes of several years are sufficient for Li Bs used in electronic devices,but infrastructure applications require lifetimes measured in decades. Users of Li Bs are faced with uncertainty about Li B lifetimes,which hinders the spread of Li Bs. Predicting Li B performance degradation and evaluating useful lifetimes by examining present performance is therefore important for planning. Our research group has developed an evaluation model for Li Bs that comprises an empirically obtained degradation speed database and a method for recognizing Li B usage patterns.
