  • This paper presents a new voltage stability model based on the mathematical relations between voltage, the level of wind power penetration, SCC and X/R at a given Point of Common Coupling (PCC) of a distribution network connected WPP. (mdpi.com)
  • The methodology used by theories to explain the size distribution of cities takes an empirical fact and works backward to first obtain a reduced form of a model, then pushes this reduced form back to assumptions on primitives. (uni-muenchen.de)

  • The global indicator used as well by European countries, the GINI coefficient offers a standardized measure to assess income distribution disparities, facilitating comparisons across different nations. (who.int)
  • Once the physical property is measured a calculation of some type generates a representation of a particle size distribution. (horiba.com)
  • The methodology behind the GINI coefficient is rooted in the Lorenz curve, a graphical representation of income or wealth distribution. (who.int)
  • We find close agreement between the distribution for large populations and the limiting case where the distribution is that of the time a Brownian motion hits a quadratic curve. (springer.com)
  • While a certain configuration tested in a lab may result in satisfactory distribution of the dissolved oxygen (DO), large scale fermenters need careful design considerations. (confex.com)
