Influence of Profile Geometry on Frictional Energy Dissipation in a Dry, Compliant Steel-on-Steel Fretting Contact: Macroscopic Modeling and Experiment

Machines, 2023
Dry, frictional steel-on-steel contacts under small-scale oscillations are considered experimentally and theoretically. As indenting bodies, spheres, and truncated spheres are used to retrace the transition from smooth to sharp contact profile geometries.

Hysteresis and Noise in Stripe and Clump Forming Systems

, 2005
We use simulations to examine hysteresis and noise in a model system that produces heterogeneous orderings including stripe and clump phases. In the presence of a disordered substrate, these heterogeneous phases exhibit 1/f$^\alpha$ noise and hysteresis ...

Hysteresis of the intertropical convergence zone to CO2 forcing

Nature Climate Change, 2021
With the unprecedented rate of global warming in recent decades, whether or not anthropogenic climate change is irreversible is an important question. Based on idealized CO 2 ramp-up until 1,468 ppm and symmetric ramp-down model experiments, here we show

A simple mechanical model of turbulence

Вестник Самарского университета: Естественнонаучная серия
This work examines the control and stabilization problems of vibrations in a hierarchical chain of oscillators with hysteresis couplings. Hysteresis coupling is formalized within the Bouc — Wen phenomenological model.

The Impact of Hysteresis Effect on Device Characteristic and Reliability for Various Fin-Widths Tri-Gate Hf_0.5Zr_0.5O₂ Ferroelectric FinFET

Crystals, 2023
In this study, we developed a facilitated ferroelectric high-k/metal-gate n-type FinFET based on Hf0.5Zr0.5O2. We investigated the impact of the hysteresis effect on device characteristics of various fin-widths and the degradation induced by stress on ...

Analysis of wasp-waisted hysteresis loops in magnetic rocks

, 2011
The random-field Ising model of hysteresis is generalized to dilute magnets and solved on a Bethe lattice. Exact expressions for the major and minor hysteresis loops are obtained.

Global and Regional Temporal Changes in Cross‐Country Inequalities of Site‐Specific Osteoarthritis Burden, 1990 to 2021

Arthritis Care &Research, EarlyView.
Objective This study examined the global and regional temporal changes in cross‐country inequalities of site‐specific osteoarthritis (OA) burden from 1990 to 2021. Methods Age‐standardized years lived with disability rates (ASYRs) for site‐specific OA across 204 countries and territories were obtained from the Global Burden of Diseases, Injuries, and ...

Synchronization of Kuromoto Oscillators on Simplicial Complexes: Hysteresis, Cluster Formation and Partial Synchronization

Entropy
The analysis of the synchronization of oscillator systems based on simplicial complexes presents some interesting features. The transition to synchronization can be abrupt or smooth depending on the substrate, the frequency distribution of the ...

Application of Least-Squares Support-Vector Machine Based on Hysteresis Operators and Particle Swarm Optimization for Modeling and Control of Hysteresis in Piezoelectric Actuators

Actuators, 2022
Nanopositioning systems driven by piezoelectric actuators are widely used in different fields. However, the hysteresis phenomenon is a major factor in reducing the positioning accuracy of piezoelectric actuators.
