Numerical solutions for lunar orbits [PDF]

, 1997
Starting from a variational formulation based on Hamilton’s Principle, the paper exploits the finite element technique in the time domain in order to solve orbital dynamic problems characterised by constrained boundary value rather than initial value ...

Numerical Solutions of ODEs using Volterra Series [PDF]

, 2006
We propose a numerical approach for solving systems of nonautonomous ordinary di®erential equations under suitable assumptions. This approach is based on expansion of the solutions by Volterra series and allows to estimate the accuracy of the ...

Depth-Extrapolation-Based True-Amplitude Full-Wave-Equation Migration from Topography

Applied Sciences, 2021
The lack of an initial condition is one of the major challenges in full-wave-equation depth extrapolation. This initial condition is the vertical partial derivative of the surface wavefield and cannot be provided by the conventional seismic acquisition ...

Self-dual Vortices in the Generalized Abelian Higgs Model with Independent Chern-Simons Interaction

, 1992
Self-dual vortex solutions are studied in detail in the generalized abelian Higgs model with independent Chern-Simons interaction. For special choices of couplings, it reduces to a Maxwell-Higgs model with two scalar fields, a Chern-Simons-Higgs model ...
