A new boundary condition treatment has been devised for two-phase flow numerical simulations in a self-aerated minerals flotation machine and applied to a Wemco 0.8 m3 pilot cell. Airflow rate is not specified a priori but is predicted by the simulations as well as power consumption. Time-dependent simulations of two-phase flow in flotation machines are …

grid—Two power sources are turned on, or the chassis requires greater than N+1 redundancy. If one source fails (which causes a loss of power to one or two power supplies), the surviving power supplies on the other power circuit continue to provide power to the chassis. Please let me know if this helps explain things better.

If in the low-power mode, a specific task (like decoding a raw image) becomes twice slower while the power consumption (watt) is also twice lower, doesn't the total power consumption remain the same for the task? If this scenario is correct, then such a mode doesn't save you any battery life. It just makes things slower.
