Probability of Synapomorphy was designed as an R script that implements a new method for evaluating synapomorphy on phylogenetic trees.
All you have to do is install R and run the script. A method that quantifies the pattern of character state distribution over a cladogram and as such is free...

This simple m-file plots the Soft Handover probability as a function of the Soft Handover Threshold value used in the UTRA Soft Handover Algorithm. The relationship has been dertived by taking the ratio between the Cell area where Soft Handovers are enabled and the total Cell area.

The 3-D Hydrogen Atom Probability Densitites model simulates the probability density of the first few (n = 1, 2, and 3, and associated l and m values) energy eigenstates for the Hydrogen atom (the Coulomb potential). The main window shows the energy level diagram for the solutions to the Coulomb...
