A review on kinetic models of dynamic recrystallization for magnesium alloys

Journal of Materials Research and Technology
Mg alloys are the lightest metallic structural material with tremendous application value. Dynamic recrystallization (DRX) is the most important grain refining and texture weakening mechanism for Mg alloys.

Data driven selection of DRX for energy efficient 5G RAN

2017 13th International Conference on Network and Service Management (CNSM), 2017
The number of connected mobile devices is increasing rapidly with more than 10 billion expected by 2022. Their total aggregate energy consumption poses a significant concern to society. The current 3gpp (3rd Generation Partnership Project) LTE/LTE-Advanced standard incorporates an energy saving technique called discontinuous reception (DRX).
