Effects of process parameters of fast EDM drilling on the recast layer

open access: yesThe International Journal of Advanced Manufacturing Technology
Abstract Fast EDM (electrical discharge machining) drilling is widely used in the machining of film cooling holes of aero-engine turbine blades. However, the EDM process will produce a recast layer, which will affect the surface performance of blades.

Shear flow-interchange instability in nightside magnetotail causes auroral beads as a signature of substorm onset

open access: yes, 2019
A geometric wedge model of the near-earth nightside plasma sheet is used to derive a wave equation for low frequency shear flow-interchange waves which transmit $\vec{E} \times \vec{B}$ sheared zonal flows along magnetic flux tubes towards the ionosphere.

Digital Surface‐Enhanced Raman Scattering With Event Counting and Spectrum Learning for Label‐Free Protein Quantification

open access: yesAdvanced Intelligent Systems, EarlyView.
A statistical and machine learning‐assisted surface‐enhanced Raman scattering (SERS) framework is developed for label‐free quantification of low‐abundance analytes, including proteins. Combining digital SERS event counting with binomial regression and an artificial neural network (ANN) trained on full spectra, the approach achieves picomolar detection ...

Participatory Policy Development: Reflections on Designing the Strong Roots for Our Futures Program in Victoria

open access: yesAustralian Journal of Social Issues, EarlyView.
ABSTRACT In this paper, we trace the journey to create the Strong Roots for our Futures Program, a government program to resource and support Traditional Owners to undertake a range of activities in areas where no state recognition existed. We provide a background to state recognition in Victoria before considering the program design, leading to an ...
