The Development Of A Stepped Frequency Microwave Radiometer And Its Application To Remote Sensing Of The Earth, Richard Forrest Harrington

Electrical & Computer Engineering Theses & Dissertations

The design, development, application, and capabilities of a variable frequency microwave radiometer are described. This radiometer has demonstrated the versatility, accuracy, and stability required to provide contributions to the geophysical understanding of ocean and ice processes. The design technique utilized a closed-loop feedback method, whereby noise pulses were added to the received electromagnetic radiation to achieve a null balance in a Dicke switched radiometer. Stability was achieved through the use of a constant temperature enclosure around the low loss microwave front end. The Dicke reference temperature was maintained to an absolute accuracy of 0.1 K using a closed-loop proportional temperature …

British Reviews Of Shikasta, Nancy Topping Bazin

English Faculty Publications

[First Paragraph] British reviewers had mixed reactions to Shikasta, the first novel in Doris Lessing's new series, "Canopus in Argos: Archives." Favorable and critical comments balanced one another, often within the same review. Furthermore, reactions tended to be extreme: either it was a magnificent novel (Times 11/15/79) or reading it was "a shameful waste of precious and irreplaceable time." (Sun Telegraph 11/18/79); or it was simultaneously great and boring. In general, British reviews of Shikasta were more perceptive than those of the second novel in Lessing's new series, The Marriages Between Zones Three, Four, and Five. Because …

Electrical & Computer Engineering Faculty Publications

Photoluminescence of cw laser-annealed silicon shows a dramatic difference in electronic behavior of the reconstructed material depending upon either creation or suppression of dislocations. Beyond a critical exposure time slip appears, and the luminescence of these samples is dominated by dislocation-related defect levels.

Finite Element Model Of A Timoshenko Beam With Structural Damping, Louis Ablen Roussos

Mechanical & Aerospace Engineering Theses & Dissertations

A numerical integration technique, a modified version of the Newmark method, is applied to transient motion problems of systems with mass, stiffness, and small nonlinear damping. The nonlinearity is cast as a pseudo-force to avoid repeated recalculation and decomposition of the effective stiffness matrix; thus, the solution technique is dubbed the "pseudo-force Newmark method." Comparisons with exact and perturbation solutions in single-degree-of-freedom problems and with a Gear-method numerical solution in a cantilevered Timoshenko beam finite element problem show the solution technique to be efficient, accurate, and, thus, feasible provided the nonlinear damping is small. As a preliminary step into the …

An Algorithm For The Electromagnetic Scattering Due To An Axially Symmetric Body With An Impedance Boundary Condition, F. Stenger, M. Hagmann, J. Scheing

Computer Science Faculty Publications

Let B be a body in R³, and let S denote the boundary of B. The surface S is described by S = {(x, y, z): (x² + Y²)^½= ƒ(z), -1≤ z ≤ I}, where ƒ analytic function that is real and positive on (-1, 1) and ƒ(±1) = 0. An algorithm is described for computing the scattered field due to a plane wave incident field, under Leontovich boundary conditions. The Galerkin method of solution used here leads to a block diagonal matrix involving 2M …

Structure Of A Subtidal Benthic Community Near Cape Charles, Virginia, R. Michael Ewing

Biological Sciences Theses & Dissertations

Species composition, distribution, and abundance of benthic invertebrates of a subtidal community were examined at a location on the lower Delmarva Peninsula near Cape Charles, Virginia. Macrobenthos was sampled quarterly between June, 1977 and June, 1978 at nine sites along a transect in Old Plantation Creek and the adjacent offshore area. Spatial and temporal patterns of numerically important species are discussed.

Sampling sites and species were grouped by a numerical classification strategy which consisted of the Bray-Curtis similarity measure and group-average clustering. Three faunal assemblages were identified with the aid of constancy and fidelity nodal analyses: (1) a tidal creek …

Norfolk In The First World War, Stephen Paul Nasca

History Theses & Dissertations

World War I brought the military establishment in the form of bases and service personnel to Norfolk. Because of Norfolk's close proximity to the various military bases, recruiting for the various branches of the Armed Forces was carried on very diligently. Those Norfolkians who did not volunteer for one of the services, or were not drafted, were encouraged to join the Norfolk Home Guard.

To build the military bases and to work in the various government plants, thousands of workers were needed. This demand for laborers strained Norfolk's public transportation, health, and social services as well as housing accommodations and …

Feeding Morphologies And Distribution Patterns Of Marine Cladocera In The Lower Chesapeake Bay, Sandra Layne Gilchrist

OES Theses and Dissertations

Temporal and spatial distributions of marine cladocera in the lower Chesapeake Bay estuary were observed over a year-long sampling period. The distributions of cladoceran species throughout the Bay were studied in relation to temperature and salinity. A survey of the species over the entire Bay is included to establish distribution patterns of the various species during a short time period.

Theoretical mathematical principles were used to predict feeding abilities of the Bay species. Mouthparts are described qualitatively and quantitatively to infer function. A mandibular index developed by Itoh (1970) was revised and employed in evaluating feeding methods interspecifically and interspecifically. …

Curing And Flow Of Thermosetting Resins For Composite Materials Pultrusion, Howard L. Price Jr.

Mechanical & Aerospace Engineering Theses & Dissertations

Fibrous composite materials for mechanical and structural applications often are expensive due to high labor costs. One economical way of making composites is pultrusion, a manufacturing process in which resin-impregnated fibers are pulled at a constant speed through a heated die which shapes the resin-fiber mass and cures the resin. Most of the work which has been done on the process has been of an empirical nature, with limited understanding of the process principles. Most of the experience with pultrusion has been gained with polyester resins and glass fibers. Very little experience has been gained with higher performance, more costly …

American Perceptions Of Chinese Communism 1945-1950, Edward C. O'Dowd

History Theses & Dissertations

This thesis explores the images of the Chinese Communists which were held by career Foreign Service Officers in China, non-career diplomats in China and the decision-making elite in Washington during the period of time from 1945 to 1950. The study centers on the questions of the tractability of the Chinese Communists to negotiations and the connection of the Chinese Communists to the Soviets. The study uses several propositions of social psychology to explain the differing images and the resulting effect on Sino-American relations.

Turbulence Spectra In A Well-Mixed Estuary, Jong Yul Chung

OES Theses and Dissertations

This dissertation is an attempt to determine and describe some of the turbulent process in a well-mixed estuary. The processes are identified by the study of turbulent velocity fluctuations. These velocity records have been analyzed using standard digital methods to obtain spectral density, spectral energy, and cross-spectra of velocity. In order to study the generation and transfer of the turbulent moment and energy, and the intermittent nature of the so-called "Bursting or "ejections and sweeps," the distribution of u, v, w, and the Reynolds stress has been studied.

Stable Equilibrium Statistical States For Spheromaks, George Vahala, Linda L. Vahala

Electrical & Computer Engineering Faculty Publications

Incompressible nondissipative magnetohydrodynamic turbulence is treated for spherical systems. From the absolute equilibrium expectation values of the fields one can investigate those initially quiescent states for which no large mean square velocity will develop. This stable state is force-free and gives rise to the Hill vortex structure for the magnetic flux surfaces.
