Ensemble Deep Learning–Based Wind Power Forecasting With Self‐Adaptive Osprey Optimization Algorithm

open access: yesEnergy Science &Engineering, EarlyView.
Design of Self‐Adaptive Osprey (SAO) algorithm: The novel SAO algorithm is designed by integrating the exploration capability of the conventional Osprey algorithm by including the self‐adaptiveness for enhancing the convergence rate. Ensemble Deep Learning for wind power forecasting: The wind forecasting is employed using the proposed Ensemble learning

Robust Control Using a Matrix Converter to Enhance Wind Turbine Systems

open access: yesEnergy Science &Engineering, EarlyView.
This study uses a more efficient and effective solution to improve the operational performance of a wind turbine‐based power system. This system uses a doubly fed induction generator and relies on a matrix converter and fractional‐order proportional–integral controller.

Minimizing Vessel Strikes to Endangered Whales: A Crash Course in Conservation Science and Policy [PDF]

open access: yes, 2009
The North Atlantic right whale is one of the most endangered of all large whales: about 350-400 individuals remain. Species recovery is, in part, contingent on reducing vessel-strike mortality.

Comparative Assessment and Benchmarking of Metaheuristic Algorithms for Dynamic Photovoltaic Array Reconfiguration Under Diverse Shading Environments

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT The solar photovoltaic (PV) installations, which are essential for renewable energy systems, are vulnerable to partial shading, resulting in considerable power losses and operational inefficiencies. The dynamic reconfiguration of PV arrays has become an effective strategy to mitigate these effects by adaptively modifying the array topology to ...

Gray Whale (Eschrictius robustus) Call Types Recorded During Migration off the West Coast of Vancouver Island

open access: yesFrontiers in Marine Science, 2018
Gray whale (Eschrichtius robustus) vocalizing behavior varies over its range, both in call type and frequency. This study adds to the growing body of passive acoustic research outside of the calving/breeding lagoons, and moves toward a description of ...

Hybrid Osprey‐Salp Swarm Optimization Algorithm for Single and Multiobjective Optimal Power Flow in Smart Grids With Renewable Energy Integration

open access: yesEnergy Science &Engineering, EarlyView.
The proposed hybrid osprey‐salp swarm optimization algorithm addresses optimal power flow (OPF) problems in smart grids incorporating solar, hydro, and thermal generators. The algorithm is validated on Institute of Electrical and Electronics Engineers 30‐, 57‐, and 118‐bus test systems across five single and multiobjective OPF scenarios.

Low prevalence of zoonotic food-borne parasites Toxoplasma gondii and Trichinella spp., but high prevalence of a potential marine Sarcocystis spp., in Eastern Beaufort Sea beluga whales (Delphinapterus leucas) harvested in the Canadian Arctic

open access: yesArctic Science
Beluga whales (Delphinapterus leucas (Pallas, 1776)) are traditional food sources for Inuit communities in the Canadian Arctic. In response to community concerns about zoonotic parasites (Toxoplasma gondii and Trichinella spp.), the aim of this study was

Sustainable Fisheries Management and the Welfare of Bycaught and Entangled Cetaceans

open access: yesFrontiers in Veterinary Science, 2018
The incidental capture of cetaceans and other protected marine wildlife in fishing gear has significant welfare implications. Many thousands of cetaceans are bycaught in fishing gear in European waters and hundreds of thousands die globally.
