Reducing and monitoring round-off error propagation for symplectic implicit Runge-Kutta schemes [PDF]
, 2017 We propose an implementation of symplectic implicit Runge-Kutta schemes for highly accurate numerical integration of non-stiff Hamiltonian systems based on fixed point iteration.

Performance Trade-Offs in Cyber–Physical Control Applications With Multi-Connectivity
Frontiers in Communications and Networks, 2021 Modern communication devices are often equipped with multiple wireless communication interfaces with diverse characteristics. This enables exploiting a form of multi-connectivity known as interface diversity to provide path diversity with multiple ...

Periodicity and Transport from Round-Off Errors [PDF]
Experimental Mathematics, 1994 We investigate the effects of round-off errors on quasi-periodic motions in a linear symplectic planar map. By discretizing coordinates uniformly we transform this map into a permutation of Z2, and study motions near infinity, which correspond to a fine discretization. We provide numerical evidence that all orbits are periodic and that the averageorder

Feedrate Scheduling of NURBS Interpolation Based on a Novel Jerk-Continuous ACC/DEC Algorithm
IEEE Access, 2018 In order to improve the motion smoothness while maintaining the machining efficiency of the non-uniform rational B-spline (NURBS) interpolation, a novel jerk-continuous acceleration/deceleration (ACC/DEC) algorithm and the corresponding feedrate ...

Regularized Yield Surfaces for Crystal Plasticity of Metals
Crystals, 2020 The rate-independent Schmid assumption for a metal crystal results in a yield surface that is faceted with sharp corners. Regularized yield surfaces round off the corners and can be convenient in computational implementations.

The Riemann-Lebesgue Integral of Interval-Valued Multifunctions
Mathematics, 2020 We study Riemann-Lebesgue integrability for interval-valued multifunctions relative to an interval-valued set multifunction. Some classic properties of the RL integral, such as monotonicity, order continuity, bounded variation, convergence are obtained ...
