Feedback Stabilization Methods for the Numerical Solution of Systems of Ordinary Differential Equations [PDF]
, 2008 In this work we study the problem of step size selection for numerical schemes, which guarantees that the numerical solution presents the same qualitative behavior as the original system of ordinary differential equations, by means of tools from ...

An Embedded System-Based Snap Constrained Trajectory Planning Method for 3D Motion Systems
IEEE Access, 2019 Computer Numerical Control (CNC) is a technology made up of several blocks. Among these, lies the Trajectory Planning block, responsible for reference profile generation that are fed to position control loops. The need for Trajectory Planning arises from

Improved upper-ocean thermodynamical structure modeling with combined effects of surface waves and M2 internal tides on vertical mixing: a case study for the Indian Ocean [PDF]
Geoscientific Model Development, 2022 Surface waves and internal tides have a great contribution to vertical mixing processes in the upper ocean. In this study, three mixing schemes, including non-breaking surface-wave-generated turbulent mixing, mixing induced by the wave transport flux ...

Oblique/Curved Tube Necking Formed by Synchronous Multipass Spinning
Metals, 2020 In this paper, we propose a method of forming a tube into an oblique/curved shape by synchronous multipass spinning, in which the forming roller reciprocates in the radial direction in synchrony with the rotation angle of the spindle while the roller ...
