Lithium evolution in intermediate age and old open clusters: NGC 752 revisited

, 2004
We present new high resolution spectroscopic observations of the intermediate age (~2 Gyr) open cluster NGC 752. We investigate the Li vs. Teff distribution and we obtain a new accurate determination of the cluster metallicity. We compare the results for

Adapted Volt-VAr Extremum-Seeking Method for Voltage Regulation and Loss Minimization in Low Voltage Distribution Networks

IEEE Access
The high penetration of Distributed Generation (DG) in the low-voltage distribution grid has raised several concerns in recent years, mainly regarding overvoltage at the buses caused by the reversal of active power flow.
