Testing Grease Consistency

open access: yesLubricants, 2021
Because of the influential role of consistency in selecting a grease for a given application, accurate and meaningful methodologies for its measurements are vitally important.

Analysis of electric field and partial discharge characteristics of cable joint stress cone dislocation defects

open access: yesIET Science, Measurement & Technology
The mechanisms governing electric field and partial discharge (PD) under stress cone dislocation remain unclear. This study employs the finite element method to explore the relationship between the electric field, externally applied voltage, and length ...

Light-cone fluctuations and the renormalized stress tensor of a massless scalar field

open access: yes, 2012
We investigate the effects of light-cone fluctuations over the renormalized vacuum expectation value of the stress-energy tensor of a real massless minimally coupled scalar field defined in a ($d+1$)-dimensional flat space-time with topology ${\cal R ...

Spontaneous curvature cancellation in forced thin sheets

open access: yes, 2006
In this paper we report numerically observed spontaneous vanishing of mean curvature on a developable cone made by pushing a thin elastic sheet into a circular container.

An analysis of the influence of clay structure on piezocone penetration test results

open access: yesShuiwen dizhi gongcheng dizhi, 2023
The effect of clay structure on the piezocone penetration test results and its mechanism are not very clear, the structured Cam-clay model is firstly program-implemented in the ABAQUS software.

Analysis of piezocone penetration under different drainage conditions with the two-phase Material Point Method [PDF]

open access: yes, 2016
The piezocone penetration test (CPTU) is commonly used to identify the soil profile and to estimate material properties. Depending on the soil type, ranging from clay to sand, undrained, partially drained or drained conditions may occur during cone ...

Hydration-induced reversible deformation of the pine cone.

open access: yesActa Biomaterialia, 2021
The scales of pine cones undergo reversible deformation due to hydration changes in order to optimize seed dispersal. This improves the survivability of the pine.

A new energy-absorbing bolt used for large deformation control of tunnel surrounding rock

open access: yesInternational Journal of Mining Science and Technology, 2022
In order to control the large deformation of tunnel surrounding rock, a new energy-absorbing bolt is developed. This bolt can be transformed into a rigid support when the deformation of the surrounding rock reaches the length of the sleeve tube, thus ...

Early ontogenetic male cone production in Pinus radiata : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Plant Biology at Massey University [PDF]

open access: yes, 2000
The tree breeding industry is interested in early ontogenetic male cone production in Pinus radiata in order to maximise the rate at which successive generations can be bred.

Bootstrap and collider physics of parity violating conformal field theories in $d=3$

open access: yes, 2019
We study the crossing equations in $d=3$ for the four point function of two $U(1)$ currents and two scalars including the presence of a parity violating term for the $s$-channel stress tensor exchange. We show the existence of a new tower of double trace
