Certain fluids exhibit an increase in flow resistance when subjected to an electric field. This electroviscous response, known as the
Winslow effect, has been the basis for development of a unique control
medium. Applying a strong potential across the fluid causes it to
"stiffen", even to the point of ceasing...
This paper presents a theoretical study of real-time bandwidth
compression systems using the Hilbert transform and associated analytic
signal concept. An analytic signal is defined as
u(t) = s(t) + [superscript ¯]js(t) , where [superscript ¯]s(t) is the Hilbert transform of the signal
s(t). A complete discussion of the properties...
I experimentally examined the adaptive significance of the
anatomical and behavioral convergence between the harrier (Circus
cyaneus, also refered to as the marsh hawk) and certain owls that are
capable of capturing prey in total darkness. Anatomically, both the
harrier and owls have evolved a sound collecting facial ruff (a...
The Indian Ocean Experiment (INDOEX) had as a primary objective
determining the radiative forcing due to anthropogenic aerosols over
climatologically significant space and time scales: the Indian Ocean during the
winter monsoon, January-March. During the winter monsoon, polluted, low-level
air from the Asian subcontinent blows over the Arabian Sea and...
This study evaluated the effect of soil compaction on the growth
of natural regeneration on volcanic ash-influenced soils in the
southern Washington Cascades. Growth of 9 to 18 year-old sapling-.
sized Ponderosa pine (Pinus ponderosa Laws.) was studied on sites
ranging from 915 to 1006 m elevation in an area...
