Barton: Testing was done on a Cartesian grid with 5x5 units.
A Cartesian grid is a special case where the elements are unit squares or unit cubes, and the vertices are integer points.
Over this map he lays one or more Cartesian grids.
The Cartesian grid represents the classical, Western tool for organizing information, including space (as in so many square feet).
The resources required in curvilinear grids are less as compared to Cartesian grids thus saving lots of memory.
These planes are endlessly repeating ruled Cartesian grids, tiled with a single signature pattern that is different for each plane.
Peter Eisenman's three office towers can be viewed as a formalist exercise, for example, but they are also a critique of the Cartesian grid.
The primary manufacturing challenge is the process of placing each sensor at a specific position (typically on a Cartesian grid) on the substrate.
As noted above, most microarrays consist of a Cartesian grid of sensors.
Up to now, only cartesian grids or a representation of the data in spectral space are implemented.
