Propagation of back‐arc extension into the arc lithosphere in the southern New Hebrides volcanic arc [PDF]

open access: yesGeochemistry, Geophysics, Geosystems, 2015
AbstractNew geophysical data acquired during three expeditions of the R/V Southern Surveyor in the southern part of the North Fiji Basin allow us to characterize the deformation of the upper plate at the southern termination of the New Hebrides subduction zone, where it bends eastward along the Hunter Ridge.

Arc pressure and weld metal fluid flow whilst using alternating shielding gases Part 1 : arc pressure measurement [PDF]

open access: yes, 2013
As part of an ongoing process to fully evaluate the effects of an alternating shielding gas supply on gas shielded welding processes, a comparison between the arc pressures generated using argon, helium, alternating shielding gases and pulsed GTAW has ...

Influence of Pedestal Fiber Splice on Tm-Doped Fiber Laser Performance

open access: yesIEEE Photonics Journal, 2023
The influence of Tm-doped pedestal fiber splice on the output performance of a large-mode-area (LMA) Tm-doped fiber laser (TDFL) has been investigated. Arc-fusion induced refractive-index deformation leads to laser leakage from the core to the pedestal ...

What can we learn from HF signal scattered from a discrete arc? [PDF]

open access: yesAnnales Geophysicae, 2009
We present observations of a discrete southward propagating arc which appeared in the mid-night sector at latitudes equatorward of main substorm activity.

Comparison of AC Flashover Performance of Snow-Accreted Insulators Under Natural and Artificial Simulation Environments

open access: yesIEEE Access, 2020
The research on snow-accreted insulators have been performed in an artificial climate chamber. However, the differences in the distribution, density and compactness of snow accretion under natural and artificial simulation environments cause differences ...

Experimental Proof of Concept of a Noncircular Rotating Detonation Engine (RDE) for Propulsion Applications

open access: yesAerospace, 2022
A noncircular engine cross-section could provide great flexibility in the integration of propulsion into the airframe. In this work, a tri-arc RDE was constructed and tested as an example of noncircular cross-sectioned RDE.

Short and long supports for constraint propagation [PDF]

open access: yes, 2013
Special-purpose constraint propagation algorithms frequently make implicit use of short supports -- by examining a subset of the variables, they can infer support (a justification that a variable-value pair may still form part of an assignment that ...

Electrical Circuit Flashover Model of Polluted Insulators under AC Voltage Based on the Arc Root Voltage Gradient Criterion

open access: yesEnergies, 2012
In order to study the flashover mechanism of polluted insulators under AC voltage, a new arc propagation criterion which is based on an arc root voltage gradient is proposed.

The simulation of terahertz waves transmission in the arc plasma

open access: yesFrontiers in Physics, 2023
The diagnostic of high-density hot plasma is a challenging task due to its high temperature and electron density. Arc plasma is one of the typical hot density plasmas, and its diagnosis is the key to develop its new applications.
