Abstract In this paper, a modified cheetah optimizer (MCO) algorithm is presented, which has been designed to address the optimal power flow (OPF) problem in power grids that utilize renewable energy sources (RES).The issue of uncertainty in cost models for wind turbines (WTs) and photovoltaics (PVs), which can result in overestimation or underesti
Dinosaur origin of egg color: oviraptors laid blue-green eggs
Protoporphyrin (PP) and biliverdin (BV) give rise to the enormous diversity in avian egg coloration.Egg color serves several ecological purposes, including post-mating signaling and camouflage.Egg camouflage represents a major character of open-nesting birds which accomplish protection of their unhatched offspring against visually oriented predator
Open Platform Cameras Based Bio-Imaging Evaluation System
With the active development of mobile devices, a variety of ultra-small, high-definition, and open platform-based cameras are being mass-produced.In this paper, we established an emulation system to verify the bio-imaging performance of the bulky and expensive high-performance cameras and various smartphone Fountains cameras that have been used in
