Herein. a method of true-temperature inversion for a multi-wavelength pyrometer based on fractional-order particle-swarm optimization is proposed for difficult inversion problems with unknown emissivity. Fractional-order calculus has the inherent advantage of easily jumping out of local extreme values; here. it is introduced into the particle-swarm algorithm to invert the true tempera... https://www.jmannino.com/amazing-price-Handlebar-for-Motovox-MBX10-and-MBX11-Mini-Bikes-amazing-deal/
