    摘要： A technique is provided for automatically controlling configuration of a power grid, which includes one or more stand-alone sub-grids. Each stand-alone sub-grid includes a power generator, and a load is associated with the stand-alone sub-grid(s). The technique includes: monitoring the power grid by monitoring power demand of a load associated with the stand-alone sub-grid(s) and the power generated by the power generator within each stand-alone sub-grid; automatically determining that a grid configuration change is required for the power grid based on the monitoring; and dynamically reconfiguring the power grid by automatically modifying a number of stand-alone sub-grids in the power grid without interrupting power to the load associated with the stand-alone sub-grid(s) of the power grid. In one implementation, the power grid is a mobile power grid, and the power generator of each stand-alone sub-grid is a portable power generator.

    摘要： EIS and EMIS methods of assessing the fatigue status of a material. The EIS method uses an electrochemical transducer cell to apply electrical perturbations to the material, and to acquire voltage and current measurements over a range of frequencies. The impedance at each frequency is calculated, resulting in impedance spectrum data. This data is correlated to reference data representing the fatigue life of the material. The EMIS method is similar except that mechanical instead of electrical perturbations are applied to the material.
