For example, 800-nm posts (Fig. 3b) and 20-μm posts/500-μm posts (Fig. 3c) were combined to fabricate the three-level apertures of 800 nm/20 μm/500 μm (from top to bottom).

An example of organic architecture popular in the 1960s and ’70s, the house was designed to sit on the rocky landscape and rise out of it like a desert plant.

Although they require more complex circuits, three-level inverters are more efficient than their two-level cousins. Effective partitioning simplifies implementation of the three-level configuration.

A class of incomplete three level factorial designs useful for estimating the co-efficients in a second degree graduating polynomial are described. The designs either meet, or approximately meet, the ...
