Diffuse emissions, PM, and industry 4.0: a wry look at development of SOTA 2019-2026
In this post I provide a BTS perspective on development of SOTA for PM measurements 2019-2026, based on experiences from a number of R&D projects. This is done on the backdrop of the 2023 report by NEA and Norce about "Monitoring of diffuse emissions to air from industry".

The quest for tangible RoI from the use of generative AI for interpreting dust sensor data in metallurgical industry
Grim Gjønnes pushes back on the MIT finding that 95% of organisations see no ROI from generative AI. Using Arpuro's dust-monitoring deployments as case studies, he sketches concrete returns in heavy industry: cleaning costs, avoided failures, smarter capex.

The whole limit in ninety seconds
Why measurement range matters when the exposure limit is low. A dust sensor that stops at 10 mg/m³ reports a clean shift for a day that spent 148% of the limit in one five-minute plume.

Prediction of dynamic mooring responses of a floating wind turbine using an artificial neural network
A neural-network surrogate for mooring-line tensions on the OC3-Hywind floating wind turbine. Trained on 32 wave states, it reaches ~71% correlation with the reference solver at a fraction of the runtime — useful in early-stage design and fatigue iteration.

Real-time passive control of wave energy converters using the Hilbert–Huang transform
A passive-control strategy for wave-energy converters that adapts damping to instantaneous wave frequency rather than using static tuning. HHT supplies the frequency at every sample; the adaptive controller improves energy absorption over fixed-gain in irregular seas.
