De Kievit, Menaldum of the "upright shaft" there are two "crown wheels" The upper "crown wheel", which has 35 cogs drives an Archimedes' screw via a "crown wheel". This screw was used to pump water into the polder. The lower "crown wheel", which has 35 cogs, drives a gearwheel with 32 cogs on the axle of an Archimedes' screw, which was used to drain the polder. The axle of the screw is diameter and long. The screw is diameter. It is inclined at 10°. Each revolution of the screw lifts of water. "De Kievit" is open to the public at any time it
GNU Archimedes a simplified version, developed for students, is available on nanoHUB.org. The Ensemble Monte Carlo method is the method that Archimedes uses to simulate and predict the behavior of a devices. Being the Monte Carlo very stable and reliable, Archimedes can be used to know the characteristics of a device even before this last is built. The physics and geometry of a device is described simply by a script, which makes, in this sense, Archimedes a powerful tool for the simulation of quite general semiconductor devices. Archimedes is able to simulate a plenty of physics effects and transport for electrons and
