The Analysis of Acoustic Emission Signals from the Cylinder Head of a Diesel Engine for Fault Detection

There are many acoustic emission (AE) sources in a diesel engine. During an engine cycle, fuel injection, onset of combustion, valve impacts and piston slaps all produce AE effects.

Making Mining Licit: Gold, Commodification, and the Everyday Performance of Law in Colombia

American Anthropologist, EarlyView.
ABSTRACT Ethnographies of resource‐making have shown that the extraction of resource value from objects is premised on obviating the emplaced lifeworlds that surrounded objects before they traveled to consumer markets. Much of this literature looks at such supply‐chain disentanglement from the viewpoint of corporate and formal regulatory practices ...

Optimal Hedging Strategies in the Low‐Sulphur Bunker Fuel Landscape

European Financial Management, EarlyView.
ABSTRACT The IMO2020 regulation for the green transition in shipping turned the industry into using two compliant bunker fuels: very low‐sulphur fuel oil (VLSFO) and low‐sulphur marine gas oil (LSMGO). VLSFO futures contracts introduced in late 2019 and other energy‐related futures contracts indicate that the VLSFO contracts trading on the Singapore ...
