The chattering dynamics of an ideal bouncing ball

open access: yes, 2003
The chattering dynamics of a vibrated bouncing ball is studied numerically in reduced impact representation. A new family of chattering bands is revealed and their structure analyzed in detail.

Ultrafast oscillations in the human brain and their functional significance

open access: yesEpilepsia, Volume 67, Issue 9, Page 4745-4757, September 2026.
Abstract Objective The upper frequency limit of human brain activity remains unknown. Using ultrahigh sampling rate (≥20 kHz) intracranial microelectroencephalography, this study aimed to systematically explore and quantitatively characterize brain field oscillations beyond the established high‐frequency oscillation range (>2 kHz), and to determine ...

Aircraft cruise performance optimization using chattering controls

open access: yes, 2013
Aircraft Cruise Performance is examined by using energy-state modelling to investigate fuel-range optimal trajectories. Chattering controls are considered appropriate when the hodograph is non-convex.

Rehearsing Responsiveness: Coaching Preservice Teachers to Work Within and Beyond Standardized Lesson Plans

open access: yesThe Reading Teacher, Volume 80, Issue 2, September/October 2026.
ABSTRACT Centrally developed English lesson plans provide structure and ensure curriculum coverage, yet they can constrain preservice teachers' creativity, responsiveness, and capacity to engage students meaningfully. Although this tension is well documented, there is limited practical guidance for teacher educators in University Teacher Preparation ...

Chattering-free sliding mode synchronization control for a hybrid mechanism

open access: yes, 2017
For a hybrid mechanism used for automobile electro-coating conveying, a chattering-free sliding mode synchronization controller is proposed to improve the synchronization performance during motion process. The Jacobi matrix of the mechanism is calculated

Evaluating Fragmentation Detection in Block Caves Using Synthetic Muon Tomography

open access: yesGeophysical Prospecting, Volume 74, Issue 7, September 2026.
ABSTRACT Muon tomography is a geophysical imaging technique with growing application across a range of geological and industrial settings. By observing the arrival of naturally occurring muons, it is possible to reconstruct subsurface density distributions in three dimensions.

Robustness vs Chattering-effect study for the Sliding Mode Control

open access: yes, 2019
In Sliding Modes control literature, a popular paradigm says that the so called “chattering-effect” (undesirable mechanical vibrations on the plant under control) can be reduced or even removed at all without affecting the control robustness ...
