A comparison between simulation and experiment of virtual machining in CNC turning machine considering kinematic motion deviations, tool wear and workpiece deflection errors

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2019
The virtual machining is one of the most important techniques to estimate the complex various machining parameters of machined parts before operating the real machining, in order to obtain the accuracy, precision and reliability.

Global Dynamics of Subsurface Solar Active Regions [PDF]

open access: yes, 2012
We present three-dimensional numerical simulations of a magnetic loop evolving in either a convectively stable or unstable rotating shell. The magnetic loop is introduced in the shell in such a way that it is buoyant only in a certain portion in ...

Centre-to-limb spectro-polarimetric diagnostics of simulated solar photospheric magneto-convection: signatures of photospheric Alfven waves [PDF]

open access: yes, 2014
Using numerical simulations of the magnetised solar photosphere carried out with the radiative magneto-hydrodynamic code, MURaM, and detailed spectro-polarimetric diagnostics of the simulated photospheric 6302A FeI line, spectro-polarimetric signatures ...

An Energy-based Approach to Ensure the Stability of Learned Dynamical Systems

open access: yes, 2020
Non-linear dynamical systems represent a compact, flexible, and robust tool for reactive motion generation. The effectiveness of dynamical systems relies on their ability to accurately represent stable motions.

Analysis of chaotic motion and its shape dependence in a generalized piecewise linear map [PDF]

open access: yesPhysical Review E, 2001
We analyse the chaotic motion and its shape dependence in a piecewise linear map using Fujisaka's characteristic function method. The map is a generalization of the one introduced by R. Artuso. Exact expressions for diffusion coefficient are obtained giving previously obtained results as special cases.

Sketching-out virtual humans: From 2d storyboarding to immediate 3d character animation [PDF]

open access: yes, 2006
Virtual beings are playing a remarkable role in today’s public entertainment, while ordinary users are still treated as audiences due to the lack of appropriate expertise, equipment, and computer skills.

A New Fractional-Order Chaotic System with Different Families of Hidden and Self-Excited Attractors

open access: yesEntropy, 2018
In this work, a new fractional-order chaotic system with a single parameter and four nonlinearities is introduced. One striking feature is that by varying the system parameter, the fractional-order system generates several complex dynamics: self-excited ...

Seismic Resistant Bridge Columns with NiTi Shape Memory Alloy and Ultra-High-Performance Concrete

open access: yesInfrastructures, 2020
Reinforced concrete bridge columns often endure significant damages during earthquakes due to the inherent deficiencies of conventional materials. Superior properties of the new materials such as shape memory alloy (SMA) and ultra-high-performance ...
