USA Today: Scientists, for the first time, have a clearer picture of what causes the "urban heat island" effect, a common phenomenon that makes cities swelter by as much as 22 degrees more than the nearby countryside, especially at night in the summer. Previously, researchers thought that evaporation was the main reason why rural areas stay cooler than cities. (Evaporation, which absorbs heat energy, is greatly reduced when cement and concrete replace grass, trees and plants.) Study lead author Lei Zhao of...

Modeling Uncertainty In Urban Propagation Using Monte Carlo Theory
2014-07-08 15:51:16| rfglobalnet Home Page
Monte Carlo provides an opportunity to handle uncertainty in a scenario by randomly sampling input parameters to obtain results for each unique situation and providing a bound for best and worst case scenarios. One type of Monte Carlo parameter is the Monte Carlo material, which allows the calculation engine to vary its parameters without re-running the scenario. This application note demonstrates how to utilize Monte Carlo materials within REMCOM’s Wireless InSite to vary material properties quickly and efficiently.
