New Runge–Kutta–Nyström methods especially designed for the numerical integration of perturbed oscillators are presented in this paper. They are capable of exactly integrating the harmonic or unperturbed oscillator. We construct an embedded 4(3) RKN pair that is based on the FSAL property. The new method is much more efficient than previously derived RKN methods for some subclasses of problems....

Interdependence between the subsystems of an enterprise is one of the driving reasons for integrating the enterprise. Integration attempts to manage those interdependencies so all subsystems work harmoniously together to achieve the enterprise goals. Prior to embarking on an enterprise integration project the interdependencies need to be analyzed. Unfortunately, interdependence between subsyste...

Major industrial and governmental efforts in information sharing and integration require building or migrating applications using heterogeneous component systems. This style of software development enjoys the benefits of reusability, adaptability, and evolvability. However, as with most component integration attempts, interoperability problems arise. Although there are several strategies that c...
