The main differencebetweenULandETLlisted products is that ETL doesn’t create its own standards for certification. UL develops standards that are used by other organizations, including ETL. Both are Nationally Recognized Testing Laboratories (NRTLs). They serve as non-governmental labs that operate in...
Similar to the results indicated in Figure 7, the deviation between the two solutions increases with frequency. At a frequency of 101 Hz, the two modeling results are in good agreement, as indicated in Figure 10a–d, for both real and imaginary parts of the x-component electrical field with...
The differences between SWAT simulated pre-development and observed contemporary loading regimes from this study point to a need for practical loading targets that support contemporary management and integrated flow and pollutant loading regimes. Keywords: sediment; nitrogen; phosphorus; ecohydrology; pre-...
For the losing control problem, this paper presents a solution of indirectly controlling torque by controlling the angle difference between the power motor (PM) stator flux and the control motor (CM) stator flux (called as the flux-angle-difference). Firstly, based on the CM static coordinate ...
