Modern day digital systems employ frequency
synthesizers to provide a common clock to the system.
They are undergoing large scale integration due to which, mitigation
of the effect of noise on power supply has become a major design consideration
in clocking circuits. Rapid scaling of CMOS technology mandates the
design...
Oxytocin is a hormone well know for the stimulation of childbirth and milk letdown in mammals. Large levels of the hormone are also released during angiogenesis in the growth of the corpus luteum (CL), a temporary endocrine gland that forms on the ovaries following ovulation. Levels of oxytocin decline after...
Azaspiracid has generated an enormous amount of scientific interest in the fourteen years since its initial discovery. The structure contains a 6,5,6 bis-spiroketal, a [3.3.1] bicyclic ketal and a 6,5-spiroaminal linkage as key moieties. With 9 rings, 20 stereocenters and three alkenes, the azaspiracid immediately attracted the interest of the...
The objective of this project was to develop an analytical model of a light-framed wood structure using a prevalent structural analysis computer program in order to evaluate system effects and define load paths within the structure, especially under extreme wind events. Simplified modeling techniques and material definitions were developed and...
This dissertation presents an incremental analog-to-digital converter (ADC) with digital digital-to-analog converter (DAC) mismatch correction. A theoretical time-domain analysis technique was developed to predict the noise performance of the incremental ADC, and a new optimization technique was proposed to minimize the output noise.
In the calibration mode, the incremental ADC...
The objective of this thesis is to provide an initial demonstration of two-terminal and three-terminal electronic devices employing amorphous multi-component metallic film
(AMMF) electrodes. Such a demonstration is successfully achieved in the fabrication of metal-insulator-metal (MIM) diode and hot electron transistor (HETs) structures employing ZrCuAlNi AMMF electrodes. The ultra-smooth surface...
This thesis explores open questions regarding molecular forms and interactions of natural and synthetic aromatic compounds present in soils and sediments.
Plant biomass-derived black carbon (biochar) generated through incomplete natural and anthropogenic combustion processes is a major source of aromaticity in terrestrial ecosystems. Chapter one represents a detailed account of...
A proposed state-and-transition model (STM) for the Deep Sand Savannah ecological site in central New Mexico was developed using historical data and expert knowledge. This STM was tested utilizing data from short and long term one-seed juniper (Juniperus monosperma (Engelm.) Sarg.) control experiments initiated in 1981 and 1985. Utilizing data...
A relatively new model of error control is the limited magnitude error over high radix channels. In this error model, the error magnitude does not exceed a certain limit known beforehand. In this dissertation, we study systematic error control codes for common channels under the assumption that the maximum error...
Phenolic compounds are known to have biological activity with beneficial effects on human health. Fruit of cultivated tomatoes (Solanum lycopersicum L.) are a major source of phenolics in the U.S. diet because this crop is the second most consumed vegetable per capita, but actual levels are low compared to other...
