An Optimal Fourth-Order Finite Difference Scheme for the Helmholtz Equation Based on the Technique of Matched Interface Boundary

Dongsheng Cheng, Jianjun Chen, Guangqing Long • Discrete Dynamics in Nature and Society (2021)

In this paper, a new optimal fourth-order 21-point finite difference scheme is proposed to solve the 2D Helmholtz equation numerically, with the technique of matched interface boundary (MIB) utilized to treat boundary problems. For the appr...

The pathology of public policy

Brian W. Hogwood, B. Guy Peters (1985)

Governments, like people, suffer in various ways when their internal functions go awry. But, unlike medical pathology, there is no recognized system of classification for the malfunctioning of policymaking. Building on the analogy between t...
