Occupational Exposure to Ultrafine Particles in Metal Additive Manufacturing: A Qualitative and Quantitative Risk Assessment. [PDF]
Int J Environ Res Public Health, 2021 Ultrafine particles (UFPs) can be released unintentionally during metal additive manufacturing (AM). Experts agree on the urgent need to increase the knowledge of the emerging risk of exposure to nanoparticles, although different points of view have ...

Advanced Photonics Research, Volume 3, Issue 4, April 2022., 2022 Herein, two radiometric models for predicting the radiation field of side‐emitting fiber light guides and fabric structures are presented. Testing these models against experimental data shows that the fiber's longitudinal emission is decisive near its surface and that the fiber's angular emission determines the far field radiation.

Advanced Optical Materials, Volume 8, Issue 18, September 18, 2020., 2020 A novel method is introduced for estimating the angular scattering profile of laser‐written structures in optical fibers using model predictions and experimental data. Fourier microscopy is employed to capture almost 4p solid angle scattering data. Such data may help in the design of fiber optical light diffusers and fiber probes with tailored emission

Impulsive noise reduction for transient Earth voltage‐based partial discharge using Wavelet‐entropy
IET Science, Measurement &Technology, Volume 10, Issue 1, Page 69-76, January 2016., 2016 Partial discharge (PD) is caused by the localised electrical field intensification in insulating materials. Early detection and accurate measurement of PD are very important for preventing premature failure of the insulating material. Detection of PDs in metal‐clad apparatus through the transient Earth voltage method is a promising approach in non ...

Oxford Journal of Archaeology, Volume 43, Issue 2, Page 173-194, May 2024.Summary This paper sets out new recommendations for recording structural iron nails. Despite their ubiquity, iron nails have received limited analytical and interpretative attention and recording practices are highly variable. Too often current recording is time‐consuming and costly without providing meaningful information.
