Surface Area Of A Cylinder

This is an extension of my single rotor analysis code.The function is based on the mathematical treatment of rotating rotors in "Principles of Helicopter Aerodynamics" by Dr. J.Gordon Leishman The numerical method does this by using Blade Element Momentum Theory (BEMT) to calculate the inflow...

This package includes files for modelling nonlinear dynamic systems using a recurrent generalized neural network. The learning scheme uses the complex method of nonlinear nonderivative optimization, thereby avoiding the problems of computing the derivative of an infinite impulse response filter...

This one line function adds up the ascii values of a string and returns the total as a checksum. Also included is a variation which returns the checksum mod 256 (so it can be used as a single byte).The same technique can be used to add up a list of numbers, or to return the average of a list...

We compare computed temperature distributions using both pdepe and analytical solutions for different geometries (slab, cylinder and sphere). Solids are kept initially at uniform temperature. For t>0, the boundary surface is kept at constant temperature. Results show excellent agreement....
