The attitude closed-loop control of the parallel platform in working space needs to determine relationship between pose top moving and length each mechanical arm, that is, kinematics problem platform. In this study, model six-degree-of-freedom was established. forward solution algorithm based on Newton–Raphson iteration studied. method usually adopts a numerical solution, which often multiple i...

The concurrent FE2-method is a very powerful and flexible computational tool for multi-scale problems. However the effort high. conventional, staggered (“nested Newton”) solution scheme solves microscopic problem iteratively within each macroscopic Newton-Raphson (NR) iteration, although deformation gradients as boundary conditions at micro scale are only estimates. In this contribution monolit...

This paper presents a study of multiprecision division on processors containing word-by-word multipliers. It compares several algorithms by first optimizing each for the software environment, and then comparing their performances on simple machine models. While the study was originally motivated by floating-point division in the small-word environment, the results are extended to multiprecision...
