Estimating Operating States of Numerical Control Milling Machines Using Wi-Fi Sensing and Channel State Information
This study investigates whether wi-fi sensing, through channel state information (CSI), can estimate the operating state and the material machined by a numerical control (NC) milling machine without contact sensors. The research...
Modelling water use efficiency in a dynamic environment
Intrinsic water use efficiency (Wi), the ratio of net CO2 assimilation (A) over stomatal conductance to water vapour (gs), is a complex trait used to assess plant performance. Improving Wi could lead in theory to higher...
The Pitfalls of the Certificate-Based User Authentication Scheme on Korean Public Websites
Hun Park
Jan 01, 2024
The Korean government has employed a certificate-based user authentication scheme powered by Internet Explorer and ActiveX plug-ins for the past two decades. Users must obtain accredited digital certificates, install all...

Bulk molybdenum field emitters by inductively coupled plasma etching.
N Zhu, MT Cole, WI Milne, J Chen
Dec 16, 2016
In this work we report on the fabrication of inductively coupled plasma (ICP) etched, diode-type, bulk molybdenum field emitter arrays. Emitter etching conditions as a function of etch mask geometry and process conditions were...
Photoluminescence spectroscopy of carbon nanotube bundles
We investigate photoluminescence of nanotube bundles. Their spectra are explained by exciton energy transfer between adjacent tubes, whereby excitation of large gap tubes induces emission from smaller gap ones. The consequent...
The dynamic interaction effects of railway tunnels
In cities around the world, underground railways offer an environmentally friendly solution to society’s increasing demand for mass transport. However, they are often constructed close to sensitive buildings, where the...
