This thesis describes the design of a baseband digital predistortion
architecture for radio frequency (RF) amplifier linearization. Existing amplifier
linearization techniques are first examined. The nonlinearity of an amplifier can
be characterized as amplitude-to-amplitude distortion and amplitude-to-phase
distortion. The distortion can be corrected by providing a predistorted driver
signal (both...
Hydrogen cyanamide (CY) has been used to break rest
in temperate crops, but levels used to overcome rest are
sometimes toxic to plants. The rest breaking effect of CY
is thought to involve peroxide metabolism. Inhibition of
catalase by CY has been proposed as a mechanism for
overcoming dormancy in...
