A Green's function calculation of the far field radiation patterns of EMAT's is presented. The approach is based upon (a) closed form expressions for the eddy current and static magnetic field distributions, established by the EMAT, which react to produce the driving Lorentz forces and (b) a Green's function derived from the steepest descent approximation to the far field response of an arbitar...

Free energy calculation has long been an important goal for molecular dynamics simulation and force field development, but historically it has been challenged by limited performance, accuracy, and creation of topologies for arbitrary small molecules. This has made it difficult to systematically compare different sets of parameters to improve existing force fields, but in the past few years seve...

A novel code for the approximate computation of long-range forces between N mutually interacting bodies is presented. The code is based on a hierarchical tree of cubic cells and features mutual cell–cell interactions which are calculated via a Cartesian Taylor expansion in a symmetric way, such that total momentum is conserved. The code benefits from an improved and simple multipole acceptance ...

This paper uses a novel approach to investigate the effect of wave-current interactions on wave loads vertical surface piercing cylinder in representative current and conditions North Sea wind farms. We used an iterative method experiments ensure same nominal sea states at location installed different for each state. While earlier studies have focused crest statistics, we here look force statis...

Theoretical tire models are often used in dynamics analysis and design. In the past, scholars have carried out a lot of research on theoretical model modeling; however, little progress has been made its solution. This paper focuses numerical solution model. New force moment calculation matrix equations constructed, different iterative methods compared. The results show that modified Richardson ...

An iterative algorithm is adopted to construct approximate representations of matrices describing the scattering properties arbitrary objects. The method based on implicit evaluation responses from iteratively generated excitations. does not require explicit knowledge any system (e.g., stiffness or impedance matrices) and well-suited for use with matrix-free full-wave solvers, such as FDTD, FEM...
