Hurricane Sandy and engineered response created habitat for a threatened shorebird

open access: yesEcosphere, 2019
The intensity of Atlantic Ocean hurricanes is predicted to increase, and although disturbance is recognized as a fundamental driver of ecological processes, the benefits of hurricanes to ecological systems are seldom acknowledged.

Experimental Investigation on the Acoustic Scattering Matrix for a Centrifugal Pump

open access: yesProceedings, 2018
Fluid-dynamic noise in centrifugal pumps as a significant sound source in piping systems has gained high attention due to the requirements of vibration and noise reduction in many fields. The acoustic characteristics of the fluid-dynamic noise from pumps

Robust decentralized model predictive control approach for a multi-compressor system surge instability including piping acoustic

open access: yesCogent Engineering, 2018
One of the major problems in modern gas compressing stations is related to surge control of compression system with multi-compressor. Due to the coupled system dynamics, standard controllers can interfere with each unit′s performance.

Piping and woody plants in peatlands: Cause or effect? [PDF]

open access: yes, 2005
This paper presents, for the first time, evidence to show that Calluna species are one causative factor of piping in blanket peat catchments. Ground-penetrating radar survey on 960 plots illustrated that piping was prevalent throughout blanket peats ...
