Puccinimethode - DDA

De gemeente Amsterdam neemt design serieus en zet het ook serieus in: net als bij andere projecten vormt dit 'designsysteem' voor het straatbeeld van de stad daarvoor het bewijs. De Puccinimethode ligt logischerwijs een beetje onder de oppervlakte, maar is enorm betekenis- en impactvol.

State-Space Design Method for Control Systems .

29.11.2010 · To introduce the state space design method, we will use the magnetically suspended ball as an example. The current through the coils induces a magnetic force which can balance the force of gravity and cause the ball (which is made of a magnetic material) to be suspended in midair. The modeling of this system has been established in many control text books (including ...

Three ball nut recirculation methods - Linear .

Deze pagina vertalen

The ball nut recirculation method is a determining factor for the smoothness of motion and size of the ball screw assembly. It also has a significant influence of the screw's maximum speed, or DN value, based on the return mechanism's design and ability to handle the forces that arise when changing the speed and direction of balls.

Ballot - Wikipedia

Poor designs lead to confusion and potentially chaos if large numbers of voters spoil or mismark a ballot. The "butterfly ballot" used in the Palm Beach County, Florida 2000 U.S. presidential election (a ballot paper that has names down both sides, with a single column of punch holes in the center, which has been likened to a maze [9] [10] ) led to widespread allegations of mismarked ballots.
