Scan-It: A Computer Vision Model Motivated By Human Physiology And Behavior, John G. Keller

Theses and Dissertations

This dissertation details the development of a new computational vision model motivated by physiological and behavioral aspects of the human visual system. Using this model, intensity features within an artificial visual field of view are extracted and transformed into a simulated cortical representation, and a saccadic guidance system scans this field of view over an object within an image to memorize that object. The object representation is thus stored as a sequence of feature matrices describing sub-regions of the object. A new image can then be searched for the object (possibly scaled and rotated), where evidence of its presence is …

Lead Shot Concentration In Soil At The Overton Wildlife Management Area, Nevada, George R. Bertoty

UNLV Theses, Dissertations, Professional Papers, and Capstones

During the spring of 1998, soil samples were collected from two areas at the Overton Wildlife Management Area (OWMA), located in the Moapa Valley of Clark County, Nevada. Lead shot has been banned for the hunting of waterfowl since 1986 but is still legal for upland game hunting. Both types of hunting occur at OWMA. One area sampled is a cultivated field and serves primarily as a dove hunting area. The other area is primarily a waterfowl hunting area and is flooded during the waterfowl-hunting season. Lead shot was recovered from 83% of the samples from the dove hunting area, …

Varietal Differences In The Total And Enantiomeric Composition Of Theanine In Tea, K. Helen Ekborg-Ott, Andre Taylor, Daniel W. Armstrong

Chemistry Faculty Research & Creative Works

Theanine is the main amino acid component in tea. It usually constitutes between 1 and 2% of the dry weight of the tea leaves. It is as prevalent in tea as all other free amino acids combined. Both enantiomers of theanine were found to have a similar sweet taste, with little or no aftertaste. It was found that black and half-green teas (except for Formosa Oolong) contained as much, or more, theanine as green teas. No correlation was found between the absolute concentration of theanine in tea and its enantiomeric composition. An inverse correlation was found between certain grades of …

Iodate Transformation By Marine Phytoplankton, Ajcharaporn Udomkit

OES Theses and Dissertations

The speciation and distribution of iodine in the oceans are partly under biological control. Phytoplankton are suspected to mediate the transformation of iodate to iodide via reduction by the enzyme nitrate reductase. However, there has been no direct evidence to support this hypothesis.

The influence of phytoplankton on the speciation of iodine was examined with emphasis on the transformation of iodate to iodide. Six cultures of marine phytoplankton: Skeletonema costatum, Dunaliella tertiolecta, Amphidinium carterae, Tetraselmis levis, Emiliania huxleyi, and Synechococcus sp. , have been examined for their ability to take up and reduce iodate under a reduced nitrate environment. In …

Urbanization And Environmental Change In Lynnhaven Estuary, Don W. Oswalt

OES Theses and Dissertations

The very minimal amounts of available urbanization data demonstrate that the number of residential dwellings in the Lynnhaven drainage basin increased sharply in the late 1950’s and early 1960's, and that the 1970 basin population density value of 1981 people per square mile is larger than all the burrough density values, except for the Virginia Beach burrough. Due to a lack of data, only qualitative changes in Lynnhaven’s marine environment can be noted. There is a strong suggestion of an increase in amounts of urban storm water run-off into Lynnhaven since 1937. A considerable amount of siltation has occurred since …

Patients' Reactions To Witnessing Cardio-Pulmonary Resuscitation, Lynn Andree Finch

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to describe the reactions to stress in patients witnessing a cardio-pulmonary resuscitation, in order to determine if the witnessing patients' needs are being met adequately, and to determine the effect of a specific psychological stressor on patients.

All resuscitations ("STATS") done over a two-month period at Loma Linda University Medical Center, with oriented patients in the room, were observed and recorded on an Observation Guide. A Questionnaire was also solicited from medical-surgical nursing personnel who had observed "STATS" with witnessing patients in the last three months. The Guide and the Questionnaire were developed from …

A Comparison Of Axillary And Rectal Temperatures In Children, Doris Payne

Loma Linda University Electronic Theses, Dissertations & Projects

This study was conducted on seventy-five children, three to eight years of age. The purpose was to compare a three-minute axillary with a three-minute rectal temperature. Known factors which might influence the findings were eliminated. These were emotional stress, physical exercise, antipyretic medications, cooling and heating measures, gastro-intestinal disturbances, and croupettes or oxygen tents. The range of the difference between the temperatures was from 0.8 degrees to 2.2 degrees with the mean difference of 1.13 degrees. A little less than half of the temperatures had one degree of difference. An additional thirty-two per cent were within 0.2 degrees of being …

The Affect Of Activities In The Intensive Care Unit On Patients, Dorothy Millholland Mottweiler

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to find out whether there is a relationship between what the patient can see and hear of on-going activities in the intensive care unit and patient stress. The descriptive survey method was used. A checklist was developed from several sources in literature. Data were collected by observation of individual patients in two intensive care units and by recording their behavior on the checklist. Recording of stress signs was done for five minute intervals every thirty minutes for eight hours, making sixteen intervals for every eight hour period. Nineteen separate patient observations of eight hour …

The Value Of Including Chemistry Content In The Study Of High School Biology, Ramon Duane Buckley

Dissertations and Theses @ UNI

The purpose was to evaluate the effect of including some definite chemistry content in high school biology. This evaluation was made by comparing outcomes of instruction in two different groups of a high school biology course. The two groups were equated in terms of the intelligence quotients, the sex, and the previous achievement in biology of the class members. The comparative gains in factual knowledge were measured by means of an evaluation test. The comparative gains in appreciations and interests in biology were measured with a questionnaire.
