Acoustic Emission [PDF]

, 2021
AbstractAcoustic emission (AE) is one of the most promising methods for structural health monitoring (SHM) of materials and structures. Because of its passive and non-invasive nature, it can be used during the operation of a structure and supply information that cannot be collected in real time through other techniques. It is based on the recording and

The radio-infrared correlation in galaxies [PDF]

, 2009
The radio-infrared correlation was explained as a direct and linear relationship between star formation and IR emission. However, one fact making the IR-star formation linkage less obvious is that the IR emission consists of at least two emission ...

Informal emissions

, 2022
Environmental regulations and their enforcement play a critical role in reducing emissions and their devastating effects on humanity and the environment. However, many developing countries have large informal sectors—accounting for more than 70 percent of total employment, that operate outside

Nocturnal emissions [PDF]

EMBO reports, 2011
Howy argues that sophisticated communication technology is no substitute for the face‐to‐face contacts that are vital to scientific work. Instead of ever‐fancier electronic devices, we should be focusing on making travel more efficient and humane.

Probing the Emission States of PSR J1107−5907 [PDF]

, 2019
The emission from PSR J1107−5907 is erratic. Sometimes the radio pulse is undetectable, at other times the pulsed emission is weak, and for short durations the emission can be very bright.
