This thesis presents a dynamical systems approach to transport and mixing in geophysical flows. First, new algorithms are developed that allow one to study a dynamical system that is described in a variety of ways such as by means of observational data or numerical simulations of differential equations.Next, methods available to study non-autonomous systems, such as hyperbolic trajectories and Lagrangian coherent structures, are developed. These concepts are applied to examples of interests: Mon...

More than 2300 gravity observations were made in the northern end of the Salton trough, including an underwater gravity survey of the Salton Sea. 400 gravity observations by Kovach are used to extend the gravity map southward and 700 gravity observations from oil companies and Woollard are used for part of the regional control. A complete Bouguer anomaly map of the California portion of the Salton trough area shows that the general trend of the isogal contours is parallel to the over-all northwe...

A large statistical sample of z~3 galaxies has been efficiently UV-color-selected, and confirmed spectroscopically. Here we present additional observations providing insight into the physical conditions in these Lyman Break Galaxies (LBGs), selected to be rapidly forming stars when the universe was ~15% of its current age. In Part I, we present the results of an optical/IR survey of 118 LBGs. The distribution of LBG optical/IR colors is used in conjunction with the rest-frame UV luminosity funct...

About 500 feet of Tertiary sediments is exposed in the general vicinity of the old St. Frances Dam Reservoir, in San Francisquito Canyon, Los Angeles County, California. The area where these sediments occur is located in the easternmost part of the Ventura Basin.At least 500 feet of well bedded red siltstones, shales, sandstones and conglomerates of continental origin is overlain by 2700 feet of piedmont deposits made up of coarse conglomerates, fanglomerates, and associated finer grained clasti...

Abstract is included in .pdf document.A new measurement of the momentum distribution of high energy charged cosmic ray particles at sea level has been made by means of a technique involving the use of two cloud chambers and a large electromagnet. With about twice the precision of previous determinations, the spectrum is extended to a momentum of pe = 80 Bev. For the 1547 measureable sets of tracks recorded, the positive-...

Through the examination of local and regional seismic waveform data the crust and upper mantle of southern California are investigated. Using local and regional seismic phases such as Pn, Sn, PL, and surface waves, seismic wave velocities of interesting tectonic structures are determined. These structures include the southern Sierra Nevada, San Bernardino Mountains, and the Salton Trough / Imperial Valley. Detailed studies of how seismic waves propagate at local and regional distances are also u...

The large magnet and 22" diameter cloud chamber constructed by Dr. S. H. Neddermayer and Dr. C. D. Anderson has been used in an attempt to observe mesotron disintegrations at sea level. Although no recognizable disintegrations were observed, useful data concerning energy loss of charged particles in carbon were obtained.It was found that the present theory of energy loss of electrons first derived by Bloch and others is in very good agreement with the experimental results for the energy ran...

A novel high-frequency, high-power, pilot-plant scale sonochemical reactor was developed and used to study the degradation of organic pollutants in aqueous solutions. The degradation rates of trichloroethylene, dichloromethane, and phenol were found to exceed those of similar frequency, small-scale bench reactors by factors ranging from 2.5 to 7. Experiments with 10 micromolar methyl orange in the large reactor operating at different total volumes exhibited a linear dependence between the observ...

The robust loop-shaping control methodology is applied in the flight control systemdesign of the Cranfield A3 Observer unmanned, unstable, catapult launched air vehicle.Detailed linear models for the full operational flight envelope of the air vehicle aredeveloped. The nominal and worst-case models are determined using the v-gap metric.The effect of neglecting subsystems such as actuators and/or computation delays onmodelling uncertainty is determined using the v-gap metric and shown to be signi...

Weakly electric fish use electroreception - the generation and detection of electric currents - to explore the world around them. Neurophysiological studies of these fish have greatly increased our understanding of central electrosensory processing, and have significant implications for sensory processing in the cerebellum and cerebellar-like neural structures.This thesis addresses a particular deficiency in our understanding of electrosensory systems: the input pattern of currents stimulating t...

Abstract is included in .pdf document.The reaction of N-bromosuccinimide (NBS) with [beta]-carotene in alcohol-containing chloroform results mainly in the formation of 4-keto-[beta]-carotene, 4,4 -diketo-[beta]-carotene, and 4-keto-3 ,4 -dehydro-[beta]-carotene, Their structures were clarified by relating them to known carotenoids through partial synthetic or degradative schemes. In the course of this work, the following...

NOTE: Text or symbols not renderable in plain ASCII are indicated by [...]. Abstract is included in .pdf document.Cavitation scale effects can be grouped into two major categories: susceptibility of the water to cavitation, i.e., the amount, size, and type of microbubbles or microparticulates in the water acting as inception nuclei, and flow field effects due to such factors as velocity and pressure distributions, body size and shape, viscous effects, and turbulent phenomena. Experimental invest...

The theme of this thesis is studying the outgoing thermal IR spectra of Earth and Mars. It is divided into two parts: the first part (Chapters 1-4) is focused on the variability seen in the outgoing thermal IR spectra and its application in validating model simulation, and the second part (Chapters 5-6) concentrates on the detection of cirrus (cirrus/dust aerosol) from terrestrial (Martian) outgoing thermal IR spectra.In Chapter 1, an example of climate change seen from two spectrometers seperat...
