Experimental study on the irreversible displacement evolution and energy dissipation characteristics of disturbance instability of regular joints

open access: yesDeep Underground Science and Engineering, Volume 2, Issue 1, Page 20-36, March 2023., 2023
In this study, to investigate the effect and underlying mechanism of the failure process under disturbance, a series of quasi‐static loading tests and disturbance shear tests in the vicinity of the strength limit is conducted on symmetrical regular dentate joints. Combined with the “locked patches” theory of typical gradual sliding, the failure law and

Bionic Optimization Design of Rotary Tiller Based on Fuzzy Algorithm

open access: yesMobile Information Systems, Volume 2022, Issue 1, 2022., 2022
In order to increase the structural performance of rotary tillage knife, a badger claw toe was selected as the bionic prototype of the rotary tillage knife, and the bionic optimization design of the rotary tillage knife was carried out. The structural similarity between the badger’s claw toe and the rotary tiller is 0.7073 by the fuzzy algorithm, and ...

Control of neoclassical tearing modes by Sawtooth control [PDF]

open access: yes, 2002
The onset of a neoclassical tearing mode (NTM) depends on the existence of a large enough seed island. It is shown in the Joint European Torus that NTMs can be readily destabilized by long-period sawteeth, such as obtained by sawtooth stabilization from ...

The two time-scales of the sawteeth precursors [PDF]

open access: yesNuclear Fusion, 1989
For current profiles with a slope discontinuity at 2 close to 1[q(1) = 1] and a small shear 1(1), the jump of the derivative of the magnetohydrodynamic (MHD) solution across the singular q = 1 layer is of the form is the finite inverse aspect ratio, μ ≡ 11/8(2–1) measures the ratio of the two small parameters.

Evolutionary origins and development of saw-teeth on the sawfish and sawshark rostrum (Elasmobranchii; Chondrichthyes) [PDF]

open access: yesRoyal Society Open Science, 2015
A well-known characteristic of chondrichthyans (e.g. sharks, rays) is their covering of external skin denticles (placoid scales), but less well understood is the wide morphological diversity that these skin denticles can show. Some of the more unusual of

Detection of Causal Relations in Time Series Affected by Noise in Tokamaks Using Geodesic Distance on Gaussian Manifolds

open access: yesEntropy, 2017
: Modern experiments in Magnetic Confinement Nuclear Fusion can produce Gigabytes of data, mainly in form of time series. The acquired signals, composing massive databases, are typically affected by significant levels of noise.

Study of correlations between LOC/SOC transition, intrinsic toroidal rotation reversal and TEM/ITG bifurcation with different working gases in TCV

open access: yesNuclear Fusion, 2023
The effects of different working gases on the transition from linear ohmic confinement (LOC) regime to saturated ohmic confinement (SOC) regime and its relation to the intrinsic toroidal rotation reversal phenomenon were explored in the TCV tokamak.

Error Analysis for an Algorithm That Reduces Radiative Transfer Calculations in High‐Resolution Atmospheric Models

open access: yesJournal of Advances in Modeling Earth Systems, Volume 11, Issue 12, Page 4576-4596, December 2019., 2019
Abstract This study assesses characteristics of spatial and temporal errors for net (shortwave + longwave) surface irradiances and atmospheric heating rates predicted by the Partitioned‐Gauss‐Legendre Quadrature (PGLQ) algorithm, whose aim is to economize computation of radiative transfer (RT) in high‐resolution cloud system‐resolving models (CSRMs ...

An Automatic Extraction Method of Coach Operation Information from Historical Trajectory Data

open access: yesJournal of Advanced Transportation, Volume 2019, Issue 1, 2019., 2019
Quality of travel service for road transport relies heavily on richness of transport operation data. Currently, most types of data including coach operation data are collected by manual investigation which is time‐consuming and labor‐intensive, and this significantly hinders the realization of intelligent traffic information service.
