Intraseasonal patterns of normalized difference vegetation index (NDVI), leaf area index (LAI), and phytomass were compared for four tundra vegetation types at Ivotuk, Alaska, during summer 1999. The vegetation types included moist acidic tundra (MAT

An approach to provide nonlinear active control for the first-order nonlinear classical Hill's equations is described. Both the linearized and nonlinear Hill's equations are controlled to remain close to specific invariant manifolds defined through t

From a Lagrangian approach for the development of the relative motion equations for a nonlinear Hill's problem, it is shown that the influence of a spherical primary mass takes the form of a third-body-like disturbing function expressed relative to t

A family of implicit methods based on intrastep Chebyshev interpolation has been developed to integrate initial value problems of the second-order harmonic oscillator form d 2 y dt 2 + ωy = f(y (t);t) . The procedure integrates the homogeneous part

A normalized form of Euler’s equations is rewritten in a variation of parameters approach using amplitudes and angular displacement as parameters. This new form is compact and yields a more accurate numerically integrated solution over longer simul

A complete analytical dynamic theory for the motion of Nereid has been constructed, accurate to approximately 0.01 arc second over several hundred years. The solution uses the Lie transform approach advanced by Deprit and is consistent with respect t

Euler’s equations, describing the rotation of an arbitrarily torqued mass asymmetric rigid body, are scaled using linear transformations that lead to a simplified set of first order ordinary differential equations without the explicit appearance of

The nonlinear dynamics of the pitch equation of motion for a gravity-gradient satellite in an elliptical orbit about a central body are investigated. This planar motion is shown to be either periodic, quasiperiodic, or chaotic, depending upon the val
