A fourth‐order extrapolation method for special nonlinear fourth‐order boundary value problems

Communications in Applied Numerical Methods, 1986
AbstractA fourth‐order convergent finite difference method is developed for the numerical solution of the nonlinear fourth‐order boundary value problem y(iv)(x) = f(x,y), a < x < b, y(a) = Ao,y″(a) = Bo, y(b) = A1, y″(b) = B1. The method is based on a second‐order converget method which is used on two grids, fourth‐order convergence being ...

A Fourth Order Reaction

Nature, 1948
IN a study of the reactions of metal complexes with hydrogen peroxide, in particular the system Fe3+, αα'-dipyridyl which gives the "Katalasestoss" reported by Kuhn and Wassermann1, we found it necessary to obtain data on the equilibrium and kinetics of formation of the red ferrous complex ion, Fe(Dipy)32+, formed according to the reaction : A recent

Fourth-order velocity statistics

Fluid Dynamics Research, 2001
An investigation of several fourth-order velocity statistics is described. Whereas local isotropy and local scaling are applicable to structure functions expressible as averages of differences of velocity, local isotropy and local scaling are inapplicable to the structure functions that we study.

Fourth-Order Elastic Coefficients

Journal of Applied Physics, 1964
The fourth-order elastic coefficients form an eighth-order tensor containing 6561 components of which 126 are independent for a triclinic system. From symmetry arguments it is shown that there are only eleven independent fourth-order elastic coefficients for a crystal with full cubic symmetry.

Fourth Order Differential Equations

2004
In addition to discussing general fourth order nonlinear equations with quasiderivatives, we consider sublinear equations in self-adjoint form, a two term nonlinear equation, and then fourth order linear equations.

Fourth‐order braneworld gravity

Annalen der Physik, 2010
AbstractWe discuss a general fourth‐order theory of gravity and formulate the generalized Israel junction conditions for the theory by application of a generalized Gibbons‐Hawking boundary term which is added to the action of the fourth‐order gravity theory.

Quantum theory of fourth-order interference

Physical Review A, 1988
The quantum theory of fourth-order interference of light is presented in a general format and compared with classical wave theory. The conditions under which nonclassical phenomena occur are discussed. In particular, the interference between the quantum field and classical field may give rise to a nonclassical effect.

Fourth-Order Function Synthesizers

2013
In order to develop analog function synthesizer circuits having an increased accuracy comparing with the third-order computational structures analyzed in the previous chapter, superior-order approximation functions have to be considered. The increase in the order of approximation strongly increases the complexity of the designed circuit, being ...
