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.

A study on tolerance design of machine tool components based on shape generation motions (Theoretical analysis considering rotational table positions)

open access: yesNihon Kikai Gakkai ronbunshu, 2017
The kinematic motion deviations of the five-axis machining centers are deeply influenced by the geometric deviations of the components, such as guide-ways and bearings.

MHD Modeling of Solar Coronal Magnetic Evolution Driven by Photospheric Flow

open access: yesFrontiers in Physics, 2021
It is well-known that magnetic fields dominate the dynamics in the solar corona, and new generation of numerical modeling of the evolution of coronal magnetic fields, as featured with boundary conditions driven directly by observation data, are being ...

Dimensional response analysis of bilinear systems subjected to non-pulselike earthquake ground motions [PDF]

open access: yes, 2011
The maximum inelastic response of bilinear single-degree-of-freedom systems when subjected to ground motions without distinguishable pulses is revisited with dimensional analysis by identifying time scales and length scales in the time histories of ...

Weakly electric fish use self-generated motion to discriminate object shape

open access: yesAnimal Behaviour, 2022
ABSTRACT Body movements are known to play an active role in sensing. However, it is not fully understood what information is provided by these movements. The Peter’s elephantnose fish, Gnathonemus petersii sense their environment through active electrolocation during which they use ...

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 ...

Biomechanical evaluation of a novel biomimetic artificial intervertebral disc in canine cervical cadaveric spines

open access: yesJOR Spine, 2023
Background Context Cervical disc replacement (CDR) aims to restore motion of the treated level to reduce the risk of adjacent segment disease (ASD) compared with spinal fusion.

On-line learning of shape information for object segmentation and tracking [PDF]

open access: yes, 2009
We present segmentation and tracking of deformable objects using non-linear on-line learning of high-level shape information in the form of a level set function.

Mechanical properties of tubulin intra- and inter-dimer interfaces and their implications for microtubule dynamic instability.

open access: yesPLoS Computational Biology, 2019
Thirteen tubulin protofilaments, made of αβ-tubulin heterodimers, interact laterally to produce cytoskeletal microtubules. Microtubules exhibit the striking property of dynamic instability, manifested in their intermittent growth and shrinkage at both ...
