stoneraven d2 This paper analyzes the low-frequency stability challenges that exist in a complex DC microgrid (MG) system.The converters that belong to a DC MG are categorized into different groups based on their control approach.The small-signal model of the DC MG is presented, and the conditions for system stability are derived.In some DC MG appl
Abstract As calcareous foraminifera precipitate their shells from the surrounding water stoneraven d2 mass, they are the basis of most marine radiocarbon chronologies and paleo-proxies.Nevertheless, post-mortem alteration of shells, especially addition of authigenic calcite, impact proxy records.In the Arctic Ocean, authigenic calcite overgrowth on
We investigate the cooling phenomenon of a mechanical oscillator in a double-coupled cavity optomechanical system.Our model includes two single-mode optical cavities.The left cavity is an optomechanical system with an optical parametric amplifier, and the right cavity is a standard optical cavity.The two optical cavities couple with each other by e
This article examines the array of macro and micro historical factors that stirred historical agency in the 1970s war against colonial settlerism as depicted in selected liberation war fiction.This war eventually led to a negotiated independence in April 1980.Historical fiction in the early 1980s is characterised by an abundance of fictional images
Sonochemical oxidation of organic pollutants in an aqueous environment is considered to be a green process.This mode of degradation of organic pollutants in an aqueous environment is considered to render reputable outcomes in terms of minimal chemical utilization and no need of extreme physical conditions.Indiscriminate discharge of toxic organic p
