Identical parallel machine scheduling problem for minimizing the makespan is a very important productionscheduling problem. When its scale is large, many diffic
Based on the phase diagrams, measured activities and the annexation principle, calculating models of mass action concentrations for In-Bi-Cu and In-Sb-Cu melts
A SiC/2024 composite was made by semisolid casting. The wetting between SiC and Al matrix is improved by treating SiC particles at a high temperature, coating K
