We develop a perturbation method for resonantly coupled nonlinear oscillators. By successive near-identity transformations of the original equations, one obtains new equations with simple structure ...

The three methods of variable transformation provided by PROC PRINQUAL are discussed in the following sections. On each iteration, the MTV algorithm alternates classical principal component analysis ...

Modern computing equipment is extremely fast and can also provide graphical output. Prior to the computer era, problems were often formulated in terms of a single numerical criterion which could be ...

WHEN a practical man devotes himself to the task of explaining to others the difficulties of any specialised subject on which he has been engaged for many years, the result is likely to be ...
