Nonrelative sliding gear mechanism based on function-oriented design of meshing line functions for parallel axes transmission

Advances in Mechanical Engineering, 2018
In this article, the design of a nonrelative sliding gear mechanism for parallel axes transmission is presented. First, the general meshing line functions were actively designed for the nonrelative sliding transmission between parallel axes.

Unaffected perceptual thresholds for biological and non-biological form-from-motion perception in autism spectrum conditions [PDF]

, 2010
Background: Perception of biological motion is linked to the action perception system in the human brain, abnormalities within which have been suggested to underlie impairments in social domains observed in autism spectrum conditions (ASC).

The Inverse Compositional Algorithm for Parametric Registration

Image Processing On Line, 2016
We present an implementation of the inverse compositional algorithm for parametric motion estimation. It computes a global motion between two images using a non-linear least square technique.

Opponent processes in human motion perception: shear and compression sensitivity, induced motion and motion capture [PDF]

, 1994
This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.Sensitivity to differential motion components, shearing and compressive (opposed) motion, was examined. The hypothesis that the visual system contains local

Quantum dynamics of a driven parametric oscillator in a Kerr medium

Scientific Reports, 2023
In this paper, we first analyze a parametric oscillator with both mass and frequency time-dependent. We show that the evolution operator can be obtained from the evolution operator of another parametric oscillator with a constant mass and time-dependent ...

Influence of Joint Stiffness and Motion Time on the Trajectories of Underactuated Robots

Applied Sciences, 2023
Underactuated robots have fewer actuators than degrees of freedom (DOF). Nonactuated joints can be equipped with torsional springs. Underactuated robots can be controlled in a point-to-point motion if they have a particular mass distribution that makes ...

Nonparametric and Parametric Modeling of Hydrodynamics for a Fully Appended Autonomous Underwater Vehicle

Journal of Marine Science and Engineering
Hydrodynamic models underpin Autonomous Underwater Vehicle (AUV) design, motion control, and performance evaluation. Existing methods face two critical bottlenecks: (1) conventional explicit CFD requires predefined trajectories, which fails to capture ...

On the motion of a pendulum attached with tuned absorber near resonances

Results in Physics, 2018
In this paper, the motion of two degrees of freedom of a dynamical system consists of a simple pendulum attached with tuned absorber subject to harmonic excitation is investigated. The governing equations of motion are obtained using Lagrange’s equations
