Triaxial instabilities in rapidly rotating Neutron Stars

open access: yes, 2018
Viscosity driven bar mode secular instabilities of rapidly rotating neutron stars are studied using LORENE/Nrotstar code. These instabilities set a more rigorous limit to the rotation frequency of neutron star than the Kepler frequency/mass shedding ...

Soft Magnetic Sensor Array for Amphibious Measurement of 3D Muscle Deformation Distribution for Human Motion Recognition

open access: yesAdvanced Intelligent Systems, EarlyView.
This article develops a soft magnetic sensor array to extract 3D and distributional muscle deformations, which has highly consistent measurements in amphibious environments, robustness to hydraulic pressure, and about 200 ms faster response than an inertial measurement unit, achieving over 98% classification accuracy and below 3% phase estimation ...

Testing for triaxiality with kinematic data [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1985
Des modeles cinematiques simples de galaxies elliptiques sont utilises pour montrer que si les galaxies sont triaxiales, les vitesses de rotation suivant leurs axes principaux apparents doivent etre associees a des mouvements similaires suivant leurs petits axes apparents.

Intrinsic Axis Ratio Distribution of Early-type Galaxies From Sloan Digital Sky Survey [PDF]

open access: yes, 2007
Using Sloan Digital Sky Survey Data Release 5, we have investigated the intrinsic axis ratio distribution (ARD) for early-type galaxies. We have constructed a volume-limited sample of 3,922 visually-inspected early-type galaxies at $0.05 \leq z \leq 0.06$

A multifunctional shear apparatus for rocks subjected to true triaxial stress and high temperature in real-time

open access: yesJournal of Rock Mechanics and Geotechnical Engineering
Deep engineering disasters, such as rockbursts and collapses, are more related to the shear slip of rock joints. A novel multifunctional device was developed to study the shear failure mechanism in rocks. Using this device, the complete shear–deformation
