Eoldist, a Web Application for Estimating Cautionary Detection Distance of Birds by Automatic Detection Systems to Reduce Collisions With Wind Turbines

open access: yesWind Energy, Volume 28, Issue 2, February 2025.
ABSTRACT The installation of automatic detection systems (ADSs) on operating wind energy facilities is a mitigation measure to reduce bird collisions. The effectiveness of an ADS depends on a combination of parameters, including the detection distance of the bird, its flight speed, and the time to complete the chosen action (e.g., turbine shutdown). We

Optimization-based reactive power control in HVDC-connected wind power plants [PDF]

open access: yes, 2017
One application of high–voltage dc (HVdc) systems is the connection of remotely located offshore wind power plants (WPPs). In these systems, the offshore WPP grid and the synchronous main grid operate in decoupled mode, and the onshore HVdc converter ...

Evaluation of acaricide treatments to experimentally reduce winter tick load on moose

open access: yesWildlife Society Bulletin, Volume 48, Issue 4, December 2024.
We experimentally reduced winter tick load on moose calves by testing the effectiveness of two acaricide treatments: topical permethrin (5% alone) and a combination of topical permethrin (44%) and orally administered fluralaner (25 mg/kg). We resighted moose calves through recaptures, necropsies or spring flyovers.

Technical and economic challenges for floating offshore wind deployment in Italy and in the Mediterranean Sea

open access: yesWIREs Energy and Environment, Volume 13, Issue 4, July/August 2024.
Offshore wind development complexity. Abstract Offshore wind is nowadays already well developed in the North European countries. Ninety‐nine percent of the offshore wind turbines are installed on fixed foundations in shallow waters. For areas with water depth greater than 50–60 m, the floating wind is the cheapest and mostly used technology.

Linking weather conditions and winter tick abundance in moose

open access: yesThe Journal of Wildlife Management, Volume 88, Issue 3, April 2024.
Over the last decades, the number of moose infested by winter ticks has increased in eastern Canada, possibly because milder climatic conditions are increasing winter tick survival. Our main objective was to determine which meteorological variables are more likely to influence winter tick load on moose.
