Adaptive inferential sensors based on evolving fuzzy models [PDF]

open access: yes, 2010
A new technique to the design and use of inferential sensors in the process industry is proposed in this paper, which is based on the recently introduced concept of evolving fuzzy models (EFMs). They address the challenge that the modern process industry

Effects of Compound Rectangular Subwavelength Hole Arrays on Enhancing Optical Transmission

open access: yesIEEE Photonics Journal, 2015
The optical transmission properties of the metallic film with an array of compound rectangular nanoholes are numerically investigated by the finite-difference time-domain (FDTD) method.

Low‐leakage track‐and‐hold buffer in 130‐nm CMOS with open‐gate FET bias

open access: yesElectronics Letters, 2022
The goal of this research is to design, fabricate, and test an amplifier circuit which minimizes the input bias current over the input direct current operating point of the amplifier. A biasing scheme to set the drain‐source voltage (Vds) to null the net

Wafer scale BN on sapphire substrates for improved graphene transport

open access: yesScientific Reports, 2018
Wafer scale (2”) BN grown by metal organic chemical vapor deposition (MOCVD) on sapphire was examined as a weakly interacting dielectric substrate for graphene, demonstrating improved transport properties over conventional sapphire and SiO2/Si substrates.

Extending the panel of inelastic scattering reactions availaible for dosimetry: Definition of the experimental campaign at the JSI TRIGA reactor [PDF]

open access: yesEPJ Web of Conferences
The epithermal to fast neutron domain lacks reactions to enhance the knowledge of spectrum in this energy range (1 keV to 1 MeV). Previous studies on this topic focused on 94Zr(n, γ) capture and 117Sn(n, n′) inelastic reactions.

Rapid characterisation of mixtures of hydrogen and natural gas by means of ultrasonic time-delay estimation [PDF]

open access: yesJournal of Sensors and Sensor Systems
The implementation of the “power-to-gas” concept, where hydrogen and natural gas are blended and transported in the existing network, requires a quick, on-site method to monitor the content of hydrogen in the mixture. We evaluate a rapid characterisation

Novel method to reduce the transverse sensitivity of granular thin film strain gauges by modification of strain transfer [PDF]

open access: yesJournal of Sensors and Sensor Systems, 2020
Strain gauges based on polyimide carrier foils and piezoresistive granular thin films are highly sensitive to strain. Unlike conventional metal foil, granular film strain gauges also have a pronounced sensitivity to strain acting in the transverse ...
