Matlab files include Gaussian numerical quadrature, Newton's method for finding roots, finite element method for 1D wave equation, and pattern formation (KPP anda system of two coupled PDEs).

Calculates sound speed in fresh (distilled) water as function of temperature (Celsius) using six-term Marczak equation. See "salt_water_c.m" for sea water speed calculations

Despite the fact that many phenomenon in physical or social sciences involve interaction between causal factors, it seems that very few researchers using multiple regression or structural equation modeling techniques do investigate for the presence of those interactions. If fact, in the context...

This program calculates the Vibration Response Spectrum (VRS) for a base input Power Spectral Density (PSD).The base input PSD must be in terms of acceleration.The VRS uses point-by-point multiplication of the transmissibility function times the base input PSD. It is thus more accurate than Miles...

We use the SRK equation of state to compute the correction factor due to gas-phase nonideality as a result of the high pressure applied in the ammonia synthesis. We also compute the extent of reaction. Plots of these two quantities versus pressure for temperature equal to 800K are presented. The...
