Quantifying numerical dispersion in non-orthogonal FDTD meshes

, 2002
Numerical electromagnetic models such as FDTD are widely used for the design and analysis of structures, including antennas. Numerical dispersion is one of the main sources of error that degrade the accuracy of the results-for each structure of interest,

Linear Combination of Order Statistics Moments from Log-Extended Exponential Geometric Distribution with Applications to Entropy

Mathematics
Moments of order statistics (OSs) characterize the Weibull–geometric and half-logistic families of distributions, of which the extended exponential–geometric (EEG) distribution is a particular case. The EEG distribution is used to create the log-extended

Natural Oscillations of the Five-Layer Rod Caused by the Initial Deflection

Механика машин, механизмов и материалов
The problem of natural oscillations of a five-layer rod symmetrical in thickness, resulting from the initial deflection, is considered. The three load-bearing layers are assumed to be thin and high-strength.

A numerical analysis of buoyancy-driven melting and freezing

, 2004
A numerical investigation of transient natural convective heat transfer with coupled phase change is presented. The numerical model attempts to capture the solid-fluid interface using a fixed-grid solution and is applied to two pure substance cases found
