In order to ensure joint operation of wind-PV-hydro complementary generation system with cascade scary face silhouette hydro-power owned by multiple stakeholders, an equitable and efficient allocating mechanism for incremental benefit is of great importance.Firstly, the incremental benefit from joint operation is quantified for wind-PV-hydro comple
A New Hybrid Algorithm Based on Grey Wolf Optimization and Crow Search Algorithm for Unconstrained Function Optimization and Feature Selection
Grey wolf optimizer (GWO) is a very efficient metaheuristic inspired by the hierarchy of the Canis lupus wolves.It has been extensively employed to a variety of practical applications.Crow search algorithm (CSA) is a recently proposed metaheuristic algorithm, which mimics the intellectual conduct of crows.In this paper, a hybrid GWO with CSA, namel
Genetic variability in three Amazon parrot species
Parrots al13sxb30en of the genus Amazona are among the most threatened species of the Order Pscittaciformes.This work describes allozyme polymorphisms in three Amazon parrot species - the Blue-fronted Amazon (Amazona aestiva), the Orange-winged Amazon (Amazona amazonica), and the Festive Amazon (Amazona festiva) -, and provides useful data for the
