IEEE … WebThere exist many models for computing CEME simulation, including empirical models, half-empirical or half-deterministic models and deterministic models. Most of these models cannot obtain satisfactory results due to the limitation of the capacity of computers. WebTEMPER is a two-dimensional (2-D) propagation model and thus cannot model effects such as terrain-influenced out-of-plane scattering, diffraction, and depolarization. With those limitations in mind, TEMPER can still provide useful “first-order” terrain effects for wide-area situations by combining the 2-D results for multiple bearings. sciatica pain after hip replacement
