Harmonic Trader

To create a trader ratings system for phpBB.Previously there has been no way to rate a user based on transactions conducted on phpBB forums.

A Java port of the Palm game Space Trader. This port is based upon the C# port at Space Trader for Windows. Recent improvements are being made to enhance it into a full-window application, under a new branch of development. Consult the wiki for info.

Tidal Analysis Program in PYthon (TAPPY) uses the least squares optimization function from scipy to perform a harmonic analysis (calculate amplitude and phases of a set of sine waves) of a hourly time series of water level values.

For several different reasons it could occur that we need to produce a signal from the sum of several harmonic components. In the usual case of Fourier analysis, FFT and IFFT are likely the best choice. However it could happen that:- The frequencies of the harmonic components are unevenly spaced-...
