The flooding phenomenon can be defined as the maximum attainable flow
condition beyond which the well defined countercurrent flow pattern can no longer
exist. Thus the countercurrent flow limit (CCFL) or the flooding limit may be thought
of as the flow condition at which the strong interaction between the two...
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...
With the rapid increase of the world energy demand and
consumption, the method and techniques to analyze, improve
and optimize energy conversion systems have to deal not only
with direct fuel exergy (energy) consumption, but also with
other resources, which have associated exergy consumptions,
and with environmental impacts, such as...
Radish anthocyanin extract has potential as a natural colorant because of
its pigment stability and attractive red hue. Presence of undesirable aroma
compounds could limit its applications in foods. The pungent principle of
radish, 4-methylthio-3-butenyl isothiocyanate (MTBI), is produced
enzymatically upon cell injury from its glucosinolate precursor, 4-methylthio-3-butenyl glucosinolate (MTBG),...
This investigation on fire mosaics addressed several aspects:
(1) quantifying the role of terrain variables in fire-related
mortality and historical mean fire return interval (MFRI), (2)
comparing post-burn Landsat Thematic Mapper (TM) imagery, TM
difference imagery, and aerial photo interpretation to map forest
survival after wildfire, and (3) to describe...
The purpose of the study was to assess county extension agents'
knowledge of geotextiles; to determine their current level of
information and their location on an adoption-diffusion curve; and to
determine the agents' attitudes toward the potential use of
geotextiles in agriculture, specifically in soil erosion control.
A questionnaire was...
