We study the ac-conductivity in linear response theory in the general framework of ergodic magnetic Schr¨dinger operators. For the Anderson model, o if the Fermi energy lies in the localization regime, we prove that the ac1 conductivity is bounded from above by Cν 2 (log ν )d+2 at small frequencies ν. This is to be compared to Mott’s formula, which predicts the leading term to 1 be Cν 2 (log ν )d+1 .

Grid-connected photovoltaic power systems are power systems energised by photovoltaic panels which are connected to the utility grid. Grid-connected photovoltaic power systems comprise of Photovoltaic panels, MPPT, solar inverters, power conditioning units and grid connection equipments. Unlike Stand-alone photovoltaic power systems these systems do not have batteries. When conditions are right, the grid-connected PV system supplies the excess power, beyond consumption by the connected load, to the utility grid.[1]...

Electric DC machines, as indeed any other type of electric machine, can be used to either produce electric energy from the input mechanical energy, or to convert electric energy into output mechanical energy. These two possible operating regimes are called generation and motoring.
