Tertiary Storage In Multimedia Systems: Staging Or Direct Access?, Hwee Hwa Pang

Research Collection School Of Computing and Information Systems

Multimedia applications that are required to manipulate large collections of objects are becoming increasingly common. Moreover, the size of multimedia objects, which are already huge, are getting even bigger as the resolution of output devices improve. As a result, many multimedia storage systems are not likely to be able to keep all of their objects disk-resident. Instead, a majority of the less popular objects have to be off-loaded to tertiary storage to keep costs down. The speed at which objects can be accessed from tertiary storage is thus an important consideration. In this paper, we propose an adaptive data retrieval …

Removal And Recovery Of Vocs And Oils From Surfactant-Flushed Recovered Water By Membrane Permeation, Ashish Nagnath Saraf

Theses

Surfactant-enhanced subsurface remediation appears to be capable of removing efficiently contaminants from the source area as well as the concentrated plume. Initial research was conducted on separate removal of trichloroethylene (TCE) and an oil. It was found that oil permeation and modified pervaporation are effective techniques of removing oil and TCE respectively from the simulated feed. It was found that the oil permeation technique can effectively remove 98-99% of oil from an oil-in-water emulsion. The subsurface-entrapped organic pollutants often have high boiling components along with the VOCs. A combined permeation technique is applied here to simultaneously remove TCE and n-dodecane …

Role Of Multiple Scattering In Cross-Correlated Light Scattering With A Single Laser Beam, James A. Lock

Physics Faculty Publications

Previous systems for measuring cross-correlated light scattering by small particles suspended in a liquid with multiple-scattering suppression have illuminated the particles with two laser beams. It is shown that multiple-scattering suppression should also occur in cross correlation for a system that employs a single laser beam and two closely spaced detectors with wide fields of view. The single-scattering, double-scattering, and single-double-scattering cross-term contributions to the intensity cross-correlation function are calculated. It is found that the two cross terms, when added together, are unimportant for both autocorrelation and cross correlation. The amplitude of the double-scattering term can be greatly diminished by …

Multiple-Scattering Suppression By Cross Correlation, William V. Meyer, David S. Cannell, Anthony E. Smart, Thomas W. Taylor, Padetha Tin

Physics Faculty Publications

We describe a new method for characterizing particles in turbid media by cross correlating the scattered intensity fluctuations at two nearby points in the far field. The cross-correlation function selectively emphasizes single scattering over multiple scattering. The usual dynamic light-scattering capability of inferring particle size from decay rate is thus extended to samples that are so turbid as to be visually opaque. The method relies on single-scattering speckle being physically larger than multiple-scattering speckle. With a suitable optical geometry to select nearby points in the far field or equivalently slightly different scattering wave vectors (of the same magnitude), the multiple-scattering …

Fiber-Optics Surface-Light-Scattering Spectrometer, Padetha Tin, J. Adin Mann, William V. Meyer, Thomas W. Taylor

Physics Faculty Publications

We have developed a fiber-optics surface-light-scattering spectrometer completely designed with optical fiber components. To the best of our knowledge, this is the first demonstration of a noninvasive measurement of the surface tension and the viscosity of simple liquid-vapor interfaces with a fiber-optics-based sensor system. With this approach we obtain a compact size, a significant increase in the signal-to-noise ratio, and the ability to select from a continuum of wave vectors. (C) 1997 Optical Society of America.

Developing Urban Deer Management Plans: The Need For Public Education, Deborah Green, Glen R. Askins, Phillip D. West

Wildlife Damage Management Conference

Independent public opinion surveys concerning urban deer (Odocoileus virginianus) management were conducted in two Virginia communities. A total of 346 citizens were interviewed in two Random Digit Dial telephone surveys. In addition to questions concerning management techniques and their administration, participants were asked about their experience with deer, their awareness of problems with deer in the area, and their enjoyment of deer. In both localities, non-lethal controls were preferred over lethal controls; trapping and relocation, fencing, repellents, and birth control measures were favored by a majority of residents. The only lethal control acceptable to residents in both communities …

Historical Forces Shaping Americans' Perceptions Of Wildlife And Human-Wildlife Conflicts, Michael R. Conover, Denise O. Conover

Wildlife Damage Management Conference

From colonial times until the 19th century, the dominant American view of wildlife and its management was dualistic—wildlife species were divided into good animals (those which had commercial value or could be eaten) or bad animals (those which threatened the colonists’ safety or food supply). Philosophically, early colonial Americans believed that the environment was to be manipulated for man’s purposes. Under the impact of modernization, Darwinian influence, over-exploitation of resources, and environmentally-conscious professionals, Americans in the late 19th century began to appreciate the recreational value of wildlife and to develop a more protective attitude toward it. Still the dichotomy between …

Development Of The Virginia Cooperative Coyote Control Program To Protect Livestock, Martin Lowney, John Houben, Phil Eggborn

Wildlife Damage Management Conference

The Virginia Cooperative Coyote Control Program was created in 1990 to address increasing livestock losses to coyotes and the inability of producers to solve such problems themselves. The eastern coyote arrived in Virginia in the late 1970s or early 1980s. Lobbying efforts of agricultural groups, such as the Virginia Sheep Federation, helped create a cost-share program administered by the Virginia Department of Agriculture and Consumer Services (VDACS) and U.S. Department of Agriculture-Animal and Plant Health Inspection Service-Wildlife Services (USDA-APHIS-WS). The objective of the program was to educate producers about control methods and to alleviate damage by removing offending coyotes where …

The Press And Citizen Participation: A Content Analysis, Lisa Pelstring, James Shanahan, Ben Perry

Wildlife Damage Management Conference

We conducted a content analysis of regional New York State newspapers to assess media coverage of the Department of Environmental Conservation’s (DEC) deer management program. The goal of this analysis was to ascertain media depiction of DEC’s deer management program during the 1985-97 time period. Specifically, this research examines how deer management issues were portrayed both prior to and after implementation of a DEC public participation program (the Citizen Task Force [CTF] process) to determine if deer management issues received more favorable coverage after CTFs were implemented.

Conservation Of A Dinosaur In Modern Times: South Carolina’S Alligator Management Program, Walter E. Rhodes

Wildlife Damage Management Conference

American alligator (Alligator mississippiensis) conservation is necessary given the animal's role in wetland ecosystems and its economic value. Although the alligator appears to be no longer threatened with extinction, the reptile’s perceived reputation and a burgeoning human population combine to create a management paradox. Alligator management in South Carolina consists of a Nuisance Control Program, a Private Lands Harvest Program, and public education. Annually, over 750 alligator complaints are received by the South Carolina Department of Natural Resources (SCDNR), and harvest averages about 250 animals. To address alligator/human interaction in rural habitats, a harvest on private lands was …

The Mass Media And Stakeholders' Beliefs About Suburban Wildlife, Cynthia A. Loker, James Shanahan, Daniel J. Decker

Wildlife Damage Management Conference

This study examines how suburban audiences obtain information about 3 species in New York State (whitetail deer [Odocoileus virginianus], beaver [Castor canadensis], and Canada goose [Branta canadensis]). Respondents in 3 suburban areas were surveyed on concerns and interests about a particular species in their area. Respondents also were surveyed about preferred sources for species information and actual source use. Finally, respondents were surveyed about general media use. “Uses-and-gratifications” theory was used to characterize respondents’ information behavior for species information. Specific recommendations for communication planning are offered.

Vertebrate Damage Management: The Future Of An Evolving Profession, Robert H. Giles Jr.

Wildlife Damage Management Conference

The author argues that an objective of a new group of people taking a systems approach to large wild animal problems should be to manage damage as a cost-reducing role within a total, profitable, long-term system, not necessarily to control the "pest." The needs are for well-grounded financial analyses both for customers, the public, the resources, and the well-being of the profession. A point of view is advanced for the need for evolving pest-related operations into a new, unique profession that is involved in a profound way as an element of a cost-effective total land and human resource production system.

"Quadrupoled" Materials For Second-Order Nonlinear Optics, S. F. Hubbard, Rolfe G. Petschek, Kenneth D. Singer

Faculty Scholarship

We describe a new approach to second-order nonlinear optical materials, namely quadrupoling. This approach is valid in the regime of Kleinman (full permutation) symmetry breaking, and thus requires a two- or three dimensional microscopic nonlinearity at wavelengths away from material resonances. This "quadrupolar" nonlinearity arises from the second rank pseudotensor of the rotationally invariant representation of the second-order nonlinear optical tensor. We have experimentally investigated candidate molecules comprised of chiral camphorquinone derivatives by measuring the scalar invariant associated with the rank two pseudotensor using hyper-Rayleigh scattering. We have found sizable scalar figures of merit for several compounds using light for …

Determination Of The Preexponential Frequency Factor For Superparamagnetic Maghemite Particles In Magnetoferritin, Bruce M. Moskowitz, Richard B. Frankel, Sarah A. Walton, Dominic P. E. Dickson, K. K. W. Wong, T. Douglas, Stephen Mann

Physics

Magnetization and Mössbauer measurements on maghemite particles with an average particle diameter of 10 nm have been made in the temperature range from 5 K to 353 K spanning the superparamagnetic (SPM) and stable single domain (SD) regimes. The maghemite particles were produced within the iron-storage protein ferritin, resulting in a narrowly-sized, weakly interacting nanocomposite material called magnetoferritin. Experiments combining hysteresis measurements, low temperature remanence, and Mössbauer spectroscopy were used to characterize magnetoferritin and to provide experimental estimates of (1) the pre-exponential frequency factor ƒ₀ in the Néel-Arhennius relaxation equation; (2) the SPM threshold size at room temperature for …
