We implemented the N-services model through computer simulations. In this paper, we present insights developed into the growth and formation of a referral network of agents and how efficiently services were produced through one of our simulations.
The InfluSim Project
Making Pandemic Influenza Modelling Tools Available to the Public
With the emergence of the Mexican flu we have decided to make all our pandemic influenza modelling and simulation tools available on the web. We encourage health care policy makers to use this software. And we would appreciate if other mathematical modellers made their pandemic influenza software public, too.
The team found that students remembered the pairs much better when they first tried to retrieve the answer before it was shown to them. In a way this pretesting effect is counterintuitive: Studying a pair for 13 seconds produces worse recall than studying the pair for 5 seconds, if students in the latter condition spent the previous 8 seconds trying to retrieve or guess the answer. But the effect averaged about 10 percent better recall, and occurred both immediately after study and after a delay averaging 38 hours.
Physical sun light This will model sun lighting from NASA measurements, including atmospheric absorption adjustable through the turbidity parameter. The size of the sun can be tweak from its reference size with the relsize (relative size) parameter. To get a correct effect, the Z axis must point above, the Y axis is north and X axis is east. Physical sky light The physical sky creates a lighting setup that simulates the light of the sun and atmosphere, based on the direction of a sun lamp in the scene and a parameter named turbidity which defines the clearness of the sky. Both the sun angle and the sky clearness influence the colour of the light. Additional parameters called aconst, bconst, cconst, dconst, econst allow you to fine tune the color of the sky to simulate various atmospheric conditions.
Pyoptic is an optics and physics simulation based on python and uses scipy as a calculation engine, matplotlib and tvtk for visualisation. It is mainly intended for simple simulations of optical engineering, imaging systems, laser systems, laser transportation and applications, lens design etc.
