Diamond is a form of carbon that has been attracting attention for hundreds of years, owing to its physical and chemical properties of hardness, thermal conductivity, chemical inertness, and transparency. Labor and the long-term impact of a diverse workforce, is one of the most important factors...

A parametric family of M-estimators of scale based on the Rousseeuw–Croux Qn-estimator is proposed; estimator’s bias and efficiency are studied. A low-complexity one-step M-estimator is obtained allowing a considerably faster computation with greater than 80% efficiency and the highest...
