Congestion Mitigation In Wireless Sensor Networks Using Single-Hop Backpressure Algorithm, Vijay Shekar Mangilipalli Gangu Sham

Electrical & Computer Engineering Theses & Dissertations

Wireless sensor networks consist of a group of small components with limited resources allocated to sense the environment and transmit data to the user or interpreter. This concept is technically evolved from Sensors that are basically used to sense the environment around and collect data based on the sensing application incorporated in them. An extension to functionality of the sensors leads to the concept of sensor networks, where, in addition to gathering information at individual sensors, the data is processed and transmitted to a central station or Base station. This concept of transmitting the information from one node to the …

A discrete event simulator (DES) provides an environment to model system architecture behavior, …

Cellular Mechanism Of Arglabin-Dimethylaminohydrochloride Cytotoxicity, Xiaofei Qin

Theses and Dissertations in Biomedical Sciences

Cancer is the second leading killer in the United States. Anticancer drug development is always based on the understanding of molecular and cellular mechanisms of carcinogenesis, as well as comprehensive knowledge of potential anticancer drugs. Arglabin-dimethylaminohydrochloride (arglabin-DMA) represents one of the new classes of anti-cancer agents that have shown promise in suppressing the growth of various tumor cells. However, the cellular mechanism of arglabin-DMA cytotoxic effects on tumor cells is still unclear. The current study was to determine the farnesyltransferase (FTase) inhibitory activity of arglabin-DMA and to investigate the effects of arglabin-DMA on three proteins: Ras, Rho and cyclin kinase …

Stress Management Through Art-Making, Karina Schwarz

EVMS School of Health Professions Theses & Dissertations

Stress is a natural and necessary part of everyday existence; the symptoms related to stress are unavoidable and systemic (Frey, 2001). Acute and chronic stress can adversely affect individuals both physically and emotionally. The literature gives evidence that medical school students are not provided with the adequate tools needed to cope with stress. This study was an art-making intervention designed to decrease stress among medical students. There were 24 participants, 19 women and 5 men enrolled in the Doctor of Medicine program at Eastern Virginia Medical School. The participants completed the Perceived Stress Scale (PSS) to measure their levels of …

Red And Black Tides: Quantitative Analysis Of Water-Leaving Radiance And Perceived Color For Phytoplankton, Colored Dissolved Organic Matter, And Suspended Sediments, Heidi M. Dierssen, Raphael M. Kudela, John P. Ryan, Richard C. Zimmerman

OES Faculty Publications

Using field measurements and quantitative modeling, we demonstrate that red coloration of the sea surface is not associated with any particular group of phytoplankton and is strongly dependent on the physiology of the human visual system. Red or brown surface waters can be produced by high concentrations of most types of algae, colored dissolved organic matter, or suspended sediment. Even though light reflected by red tides commonly peaks in the yellow spectral region (570–580 nm), human color perception requires consideration of the entire spectrum of light relative to receptors within the human eye. The color shift from green to red …

Portals To Knowledge: Confluence And Conflict Between Enlightenment And Postmodern Currencies, Benjamin G. Lanier-Nabors

Reconstruction: Studies in Contemporary Culture

[Editors' Introduction]

In order to provide any viable critique of twenty-first-century discourses -- whether signified by late capitalism, epistemological hegemony, cultural domination, or globalization (the catch-word for all of these) -- one must not employ an ahistorical or static lens; alternatively, one must dredge up and analyze the sediments that underlie current discourses, and many of these sediments are found in the eighteenth century. More specifically, by reading the thoughts of such writers as Joseph Addison and Jonathan Swift, one is forced to read the links and antipathies between the discursive economies of epistemology -- philosophical, scientific, and economic -- …

Effects Of Initial Seated Position On Whiplash In Low Speed Rear-End Impacts Comparison And Study Using The Tno Rear Impact Dummy (Trid) Model, Manjunath P. Venkataramana

Mechanical & Aerospace Engineering Theses & Dissertations

Despite numerous investigations devoted to its scrutiny, injury causing mechanism associated with rear-end impact collision producing injury such as Whiplash Associated Disorder (WAD) has remained a mystery. Several criteria have been proposed to predict the injury causing mechanism, but none have been universally accepted. The challenge lies in determining a set of testing procedures representative of real-world collisions, wherein the results obtained are not only the same as human testing, but remain consistent with various subjects and impact conditions. It is hypothesized that one of the most important considerations is the effect of initial seated position (ISP).

This thesis can …

The Effect Of Humor On Elderly Well-Being, Mary M. Boone

Sociology & Criminal Justice Theses & Dissertations

The main objectives of this study were to identify the connections between the sense of humor and well-being in the elderly population, examine the benefits of humor as a coping mechanism, explore the role of humor as a preventative and therapeutic measure, and to attempt to gain a greater understanding of these connections. Humor has been the focus of study within many different domains, including psychology and medical research (immunology, pain management, cardiology, and psychoneuroimmunology), but there is a distinct lack of theory and research within the sociological realm on this topic (except in social psychology), especially involving the aging …

A Body Of Her Own: Cultural Constructions Of The Female Body In A.S. Byatt's Strange Stories, Sabine Coelsch-Foisner

Reconstruction: Studies in Contemporary Culture

[First paragraph]

Byatt's short fiction, from her first collection Sugar and Other Stories (1987) to Elementals (1998) is marked by a continuous preoccupation with the body: the body as the product of social signifying practices, the body as the site of desires, fears, and anxieties, the body as the source of experience, the body as creator and created. In brief, the body is treated as the centre of existence, consciousness and identity. Yet, these are constantly called into doubt in Byatt's stories, which depict heroines trapped between asserting their identity and submitting to cultural dictates of beauty and behavior. In …

A comprehensive study of submarine atmospheres is ongoing during deployments of U.S. Navy nuclear submarines. As part of the overall effort, a paired air sampling comparison field validation was conducted to compare the air sampling effectiveness of passive diffusive monitors compared to more traditional active air sampling methods when sampling for acrolein, formaldehyde and ozone in the enclosed submarine atmosphere. Acrolein monitors containing 2-hydroxymethylpiperidine (HMP) impregnated glass …

Generation Of Human Chorionic Gonadotropin Beta Subunit Specific Monoclonal Antibody Using A Synthetic Peptide, Zhe Huang

Chemistry & Biochemistry Theses & Dissertations

Human chorionic gonadotropin (hCG) is well known for early immunological and bioassay tests for early detection of pregnancy. Since the hormone specific beta subunit confers unique biological and immunological specificity to hCG, immunochemical measurement of hCG has achieved greater specificity and sensitivity in recent years by using either the beta subunit as an immunogen or a partially reduced beta subunit polypeptide chain. However, antiserum raised against the entire hCG beta subunit usually cross-reacts to some extent with human luteinizing hormone (hLH). hCG has been found to be present in the extract of tumors and minute quantities of hCG are synthesized …

Thermodynamic Modeling And Analysis Of Human Stress Responses, Satish C. Boregowda

Mechanical & Aerospace Engineering Theses & Dissertations

A novel approach based on the second law of thermodynamics is developed to investigate the psychophysiology and quantify human stress level. Two types of stresses (thermal and mental) are examined. A Unified Stress Response Theory (USRT) is developed under the new proposed field of study called Engineering Psychophysiology. The USRT is used to investigate both thermal and mental stresses from a holistic (human body as a whole) and thermodynamic viewpoint. The original concepts and definitions are established as postulates which form the basis for thermodynamic approach to quantify human stress level. An Objective Thermal Stress Index (OTSI) is developed by …

The Effects Of Task Partitioning And Computer Skill Level On Operator Engagement And Performance In An Adaptive Biocybernetic Environment, Todd Michael Eischeid

Psychology Theses & Dissertations

The present study examined task partitioning in an adaptive environment, utilizing the cybernetic closed-loop system of Pope et al. (1995). In that study, participants either performed a tracking task (manual condition) or monitored the tracking task (automatic condition). Changes in task mode were driven by an engagement index derived from the participant's EEG and operated under either positive or negative feedback conditions. One goal of the present study was to examine participant performance under a wider range of tracking conditions. Specifically, the task was partitioned into 3 modes: a manual mode, a partitioned mode, and an automatic mode. A second …

Electromyography (Emg) Signal Classification By Artificial Neural Networks, Behnam Dashtipour

Electrical & Computer Engineering Theses & Dissertations

EMG signal processing is one of the active fields of biomedical signal processing. One unanswered question is how to determine whether a muscle is fatigued by analyzing the EMG signal. Fatigue detection could be useful in several different practical situations. There are several studies which show there are differences between EMG signal features before fatigue and after fatigue. Generally studies are based on an analytical analysis of the EMG signal instead of a quantitative analysis. In all previous studies in EMG signal processing for fatigue/nonfatigue detection, the result is that there exist some differences between the EMG signal before muscle …

African-American Males' Perception Of Law Enforcement: A Psychophysiological Perspective, Adolph Brown Iii

Psychology Theses & Dissertations

This study compared the psychophysiological reactivity of African American and European American males to authority. Nineteen African American males and 23 European American males were randomly assigned to either be interrogated by a police officer, or see a police officer interrogate that experimenter or view a videotape of police activity. Participants' physiological reactivity, acceptance of authority, fear of negative evaluation or social anxiety, and apprehension and anxiety in stressful situations as well as EMG, SCR, heart rate, respiration, and blood pressure were measured. African American males were hypothesized to show greater physiological response than European American males and participants who …

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 …

Validation Of The Human Factors Satisfaction Questionnaire, James Carlopio

Psychology Theses & Dissertations

In order to predict behavior in organizations, it is important to understand and to consider both the individual employee and his/her interaction with the physical work environment. The main purpose of this research was to gather evidence of the validity of the Human Factors Satisfaction Questionnaire (HFSQ) in order to provide a tool with which employees' preceptions of several elements of their physical work environments can be measured. The physical work environment and its relationship to both organization theory and motivation theory is discussed. Evidence of the construct validity of the HFSQ was sought through the administration of the HFSQ …

Relationships Between Early Mother-Infant Interaction And Later Patterns Of Attachment, Christine Oakes Work

Psychology Theses & Dissertations

This study investigates the relationships between initiative and responsive attachment behaviors exchanged between mothers and infants in a free play laboratory observation, and later pattern of attachment. Pearson product-moment correlations revealed significant intercorrelations between frequencies of the different attachment behaviors studied. Factor analysis revealed seven factors, three of which were predictive of attachment security through main or interaction effects. High frequencies of infant eye contact in response to maternal initiations significantly predicted later insecure attachment. Attachment security could also be predicted from frequency rates of infant-initiated proximity seeking and vocalization, and maternal responsive non-parallel body contact. When infant gender was …

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 …
