In power systems with high wind energy penetration, the conjunction of wind power fluctuations and power system inertia reduction can lead to large frequency excursions, where the operating reserves of conventional power generation may be insufficien

Background: The objective of laser hair removal is to damage the hair follicle as much as possible without affecting the skin. This is achieved with skin cooling systems (direct or indirect). Non-contact cooling methods, especially air-cooling, have

Background: Diode laser technology with a similar wavelength to 1,064 nm Nd:YAG solid-state lasers has been used to treat vascular lesions. This wavelength range is believed to provide the best compromise between efficacy and safety for different ski
