In this case, Zn metal would be gasified owing to its low gasification point (907 °C). Thus, we determined to partially melt the Fe-Zn powder by optimizing......

of decision variables, increase the search space, and reduce the search speed. Multi-objective optimization is used in Ref. [28] to select base learners, which takes the model accuracy and diversity as two optimization goals. In this method, the diversity among base models selected by the multi-objective algorithm can not be guaranteed because the base models are selected according to a one-to-many......

in hard rocks, JUREWICZ [95] used a multi-kW CO2 laser to cut three rock types: granite, diabase and quartzite. Five traverse velocities (ranging from 25 cm/s to 125 cm/s) and four laser powers (from 5... metal oxides and most of the sulfides are more microwave sensitive. It should be noted that there is a great discrepancy in the magnitudes of loss factors of some minerals as different measurement......
