Compensation techniques for cascaded delta-sigma A/D converters and high-performance switched-capacitor circuits

Creator:: Sun, Tao
Abstract:: This thesis describes compensation techniques for cascaded delta-sigma A/D converters (ADCs) and high-performance switched-capacitor (SC) circuits. Various correlated-double-sampling (CDS) techniques are presented to reduce the effects of the nonidealities, such as clock feedthrough, charge injection, opamp input-referred noise and offset, and finite opamp gain, in SC circuits. A CDS technique...

Enhancement of Tropical Ocean Evaporation and Sensible Heat Flux by Atmospheric Mesoscale Systems

Creator:: Esbensen, Steven K. and McPhaden, Michael J.
Abstract:: The enhancement of monthly averaged evaporation by atmospheric mesoscale systems is estimated from long-term hourly observations of surface meteorological data from the Tropical Ocean Global Atmosphere (TOGA) Tropical Atmosphere Ocean (TAO) buoy moorings over the equatorial Pacific Ocean and a bulk aerodynamic flux algorithm developed as a result of the...

Air-sea heat exchange along the northern sea surface temperature front in the eastern tropical Pacific

Creator:: Thum, Nicolai
Abstract:: The atmospheric response to the oceanic forcing in the eastern Pacific along the northern equatorial sea surface temperature (SST) front is investigated in terms of sensible and latent heat flux during the 6-month period 28 July 1999 through 27 January 2000. Of particular interest is the atmospheric boundary layer (ABL)...

Statistical relationships between the mesoscale organization of convection, precipitation and the large-scale wind fields during the GATE

Creator:: De Silva, Sirilath J.
Abstract:: Data from the GARP Atlantic Tropical Experiment (GATE) was analysed in an exploratory manner to discover the characteristics of mesoscale organization of convection and it's relationship to large-scale wind profiles. Automated methods were developed to identify the convective cells and their linear organization. These automated methods use a median high-pass...

Surface heat flux estimates from NCAR electra data over the pacific warm pool during TOGA COARE

Creator:: Greiser, Christine M.
Abstract:: The warm pool region of the western tropical Pacific is of particular interest to atmospheric dynamics because it represents a significant source of energy to the atmosphere. A better understanding of heat transfer driven by mesoscale and turbulent circulations within this region could lead to improved global circulation models, and...

An observational study of the energetics and dynamical aspects of GATE cloud clusters

Creator:: Wang, Jough-tai
Abstract:: Thermodynamical and dynamical aspects of tropical cloud clusters are studied using data from the GARP Atlantic Tropical Experiment (GATE). The data set used in this study is a three-dimensional gridded set of upper-air analyses constructed by Ooyama and Chu (Hurricane Research Division, AOML/NOAA and SSEC-University of Wisconsin) for wind data...

Analysis of putative elements of plant signal transduction chains

Creator:: Verhey, Steven D.
Abstract:: The thesis begins with an introduction to signal transduction and an analysis of current understanding of plant signal transduction. There are similarities between plants and animals, but also key differences, including lack of protein kinase C and of a cAMP signaling pathway in plants, and presence in plants of calcium...

The immunological response of sheep to irradiated and non-irradiated infectious larvae of Haemonchus contortus (Rudolphi 1803) Cobb, 1898

Creator:: Stevens, James Orval
Abstract:: Ten helminth-free sheep were given two doses of 10,000, X-irradiated, H. contortus, third stage larvae 30 days apart. These animals and a group of ten non-vaccinated sheep were challenged with 50,000, normal, H. contortus, third stage larvae 60 days following the second vaccination. Antibody levels were measured in both groups...

Magnetic properties of an analog compound for cytochrome P-450

Creator:: McCann, Steven Wayne
Abstract:: This thesis describes a Mossbauer effect and electron paramagnetic resonance study of iron (III) tetraphenylporphyrinatobenzenethiolate benzene thiol, an analog compound for bacterial cytochrome P-450. The compound is unusual in that it provides a model for the two ferric reaction states of cytochrome P-450. The iron in the model compound exhibits...
