A Lambert-orbital boundary value problem can be stated as"Find the orbit/trajectory of a spacecraft that flies from position [r1] to [r2], taking a time [tf] and making [m] complete orbits before arriving at [r2]. "The solution to each Lambert-problem is NOT unique; one can travel to [r2] via the...

The submission finds two parameters a_1 and a_2, coefficients belong to a linear equation of temperature, that minimize the difference between the pressures calculated by an equation of state and the experimental values at same temperature and volume conditions.

This set of functions simply provides an easy way to work with the dispersion relation of surface waves, given by omega(k) = sqrt ( tanh(k*h0) * (g*k + gamma*k^3/rho))where omega is the pulsation (in rad/s), k the wavenumber (in 1/m), h0 the depth, g the gravity, gamma the surface tension and rho...
