โœฆ Synopsis

A method is presented based on energy balance to derive the Melnikov criterion for a forced oscillator with one degree of freedom. An integration scheme is also discussed for numerically calculating the criterion when the integrals involved cannot be evaluated analytically. The example of the forced pendulum with constant torque is considered and results from a numerical Melnikov analysis are compared with those obtained by other methods, including homoclinic tangency following.

An analysis is presented of a class of periodically forced non-linear oscillators. The systems have centers and families of periodic orbits and may have homoclinic and/or heteroclinic orbits when the forcing and damping terms are removed. First, bifurcation behavior is analyzed near the unperturbed

The hlagnus approsimation is used to fiid a closed solution to the forced anharmonic oscillator described by the SU(2) algebra. Tbc solution is compared to an esact integration of the SchrBdinger equation. TWO types of time-dependent perturbation are considered: periodic and of finite duration.

Batch process data can be arranged in a three-way matrix (batch ร‚ variable ร‚ time). This paper provides a critical discussion of various aspects of the treatment of these multiway data. First, several methods that have been proposed for decomposing three-way data matrices are discussed in the contex

We describe an alternate approach to the solitons for F q [t] introduced by Anderson. The product of the monic polynomials in F q [t] of degree i in a given congruence class can be expressed in a compact form by the solitons ``for all i at once.'' They also link the arithmetic of F q [t] gamma value
