Exploring Life Through The Depths Of The Subconscious Mind, Urszula Blaszak Jan 2004

Exploring Life Through The Depths Of The Subconscious Mind, Urszula Blaszak

HIM 1990-2015

The animation short I have produced is very personal on the subconscious level. There is no single theme; the narrator is the viewer. It is a dream sequence aiming to achieve Kafkaesque quality. About four minutes long, combined with dynamic music this piece of work is my reaction to society, to my life, ever changing surroundings, my traveling, childhood memories, and man-woman relationships, education, feelings, everyday worries, and everything else that I at the moment of producing felt like adding. It is suppose to be a portrait of me inside. I tried to recreate the everyday chaos of thoughts, emotions, …

Using Noninvasive Wearable Computers To Recognize Human Emotions From Physiological Signals, Christine Laetitia Lisetti, Fatma Nasoz Jan 2004

Using Noninvasive Wearable Computers To Recognize Human Emotions From Physiological Signals, Christine Laetitia Lisetti, Fatma Nasoz

Faculty Bibliography 2000s

We discuss the strong relationship between affect and cognition and the importance of emotions in multimodal human computer interaction (HCl) and user modeling. We introduce the overall paradigm for our multimodal system that aims at recognizing its users' emotions and at responding to them accordingly depending upon the current context or application. We then describe the design of the emotion elicitation experiment we conducted by collecting, via wearable computers, physiological signals from the autonomic nervous system (galvanic skin response, heart rate, temperature) and mapping them to certain emotions (sadness, anger, fear, surprise, frustration, and amusement). We show the results of …

Some Suggestions For Keeping National Wildlife Refuges Healthy And Whole, Reed F. Noss Jan 2004

Some Suggestions For Keeping National Wildlife Refuges Healthy And Whole, Reed F. Noss

Faculty Bibliography 2000s

National wildlife refuges have a biological conservation mandate surpassing that of any other category of public land in the United States. The National Wildlife Refuge System Improvement Act of 1997 forged a statutory requirement to maintain the biological integrity, diversity, and environmental health of refuges, Yet, considerably more guidance from science is needed if this mandate is to be interpreted in a scientifically defensible and biologically conservative manner. After evaluation of the extent to which well-accepted goals and principles of conservation biology are reflected in the wildlife refuge system mandate and in the actual design and management of refuges, it …

Correlations Between Liquid Crystal Director Reorientation And Optical Response Time Of A Homeotropic Cell, Haiying Wang, Thomas X. Wu, Xinyu Zhu, Shin-Tson Wu Jan 2004

Correlations Between Liquid Crystal Director Reorientation And Optical Response Time Of A Homeotropic Cell, Haiying Wang, Thomas X. Wu, Xinyu Zhu, Shin-Tson Wu

Faculty Bibliography 2000s

Correlations between the director reorientation time and its consequent optical response time (both decay and rise) of a homeotropic liquid crystal (LC) cell under crossed polarizers are derived theoretically based on small angle approximation. Results indicate that the optical response time is linearly proportional to the LC director reorientation time and is weakly dependent on the initial bias voltage. To validate the derived correlations, transient phase and transmittance responses at various bias voltages are analyzed numerically by solving the Erickson-Leslie equation. Pretilt angle is found to make an important contribution to the optical response time. Gray scale switching of the …

High-Yield Expression Of A Viral Peptide Animal Vaccine In Transgenic Tobacco Chloroplasts, Andrea Molina, Sandra Hervás-Stubbs, Henry Daniell, Angel M. Mingo-Castel, Jon Veramendi Jan 2004

High-Yield Expression Of A Viral Peptide Animal Vaccine In Transgenic Tobacco Chloroplasts, Andrea Molina, Sandra Hervás-Stubbs, Henry Daniell, Angel M. Mingo-Castel, Jon Veramendi

Faculty Bibliography 2000s

The 2L21 peptide, which confers protection to dogs against challenge with virulent canine parvovirus (CPV), was expressed in tobacco chloroplasts as a C-terminal translational fusion with the cholera toxin B subunit (CTB) or the green fluorescent protein (GFP). Expression of recombinant proteins was dependent on plant age. A very high-yield production was achieved in mature plants at the time of full flowering (310 mg CTB-2L21 protein per plant). Both young and senescent plants accumulated lower amounts of recombinant proteins than mature plants. This shows the importance of the time of harvest when scaling up the process. The maximum level of …

Time-Resolved Mueller Matrix Imaging Polarimetry, Ihor Berezhnyy, Aristide Dogariu Jan 2004

Time-Resolved Mueller Matrix Imaging Polarimetry, Ihor Berezhnyy, Aristide Dogariu

Faculty Bibliography 2000s

We present a new method of time-resolved Mueller matrix imaging polarimetry for spatial and temporal characterization of the polarization effects in backscattering from turbid media. The technique allows measuring the time evolution of spatially varying polarization patterns of diffusely backscattered light with picosecond resolution. A series of time-resolved polarization patterns are obtained at various time delays, are analyzed in sequence, and used to separate the polarimetric contributions of different scattering paths. Specific features of the 2D Mueller matrix components corresponding to light backscattered from colloidal suspensions were determined and characterized. The temporally- and spatially-resolved measurements permit detailed analysis of the …

Dubey, Tatiana D. Sirakova, Bassam Abomoelak, Hector R. Morbidoni, Pappachan E. Kolattukudy Jan 2004

Induction Of A Novel Class Of Diacylglycerol Acyltransferases And Triacylglycerol Accumulation In Mycobacterium Tuberculosis As It Goes Into A Dormancy-Like State In Culture, Jaiyanth Daniel, Chirajyoti Deb, Vinod S. Dubey, Tatiana D. Sirakova, Bassam Abomoelak, Hector R. Morbidoni, Pappachan E. Kolattukudy

Faculty Bibliography 2000s

Mycobacterium tuberculosis enters the host by inhalation of an infectious aerosol and replicates in the alveolar macrophages until the host's immune defense causes bacteriostasis, which leads the pathogen to go into nonreplicative drug-resistant dormancy. The dormant pathogen can survive for decades till the host's immune system is weakened and active tuberculosis develops. Even though fatty acids are thought to be the major energy source required for the persistence phase, the source of fatty acids used is not known. We postulate that the pathogen uses triacylglycerol (TG) as a storage form of fatty acids. Little is known about the biosynthesis of …

Method For Determination Of Singlet Oxygen Quantum Yields For New Fluorene-Based Photosensitizers In Aqueous Media For The Advancement Of Photodynamic Therapy, Wade William Grabow Jan 2004

Method For Determination Of Singlet Oxygen Quantum Yields For New Fluorene-Based Photosensitizers In Aqueous Media For The Advancement Of Photodynamic Therapy, Wade William Grabow

Electronic Theses and Dissertations

Photodynamic therapy (PDT) has been investigated over the past three decades and is currently an approved therapeutic modality for skin cancer, the treatment of superficial bladder, early lung and advanced esophageal cancers, and age-related macular degeneration in a number of countries. In PDT, the absorption of light by a chromophore generates cytotoxic species such as reactive singlet oxygen, leading to irreversible destruction of the treated tissue. The measurement of the singlet oxygen quantum yield is an important determinant used to evaluate the efficiency of new photodynamic therapy agents developed in the laboratory, to screen potential photosensitizers in aqueous media.The singlet …

Partitioning A Graph In Alliances And Its Application To Data Clustering, Khurram Hassan-Shafique Jan 2004

Partitioning A Graph In Alliances And Its Application To Data Clustering, Khurram Hassan-Shafique

Electronic Theses and Dissertations

Any reasonably large group of individuals, families, states, and parties exhibits the phenomenon of subgroup formations within the group such that the members of each group have a strong connection or bonding between each other. The reasons of the formation of these subgroups that we call alliances differ in different situations, such as, kinship and friendship (in the case of individuals), common economic interests (for both individuals and states), common political interests, and geographical proximity. This structure of alliances is not only prevalent in social networks, but it is also an important characteristic of similarity networks of natural and unnatural …

A Comparative Static Analysis For Invasive Species Management Under Risk Neutral Preferences, Pamela Safford Jan 2004

A Comparative Static Analysis For Invasive Species Management Under Risk Neutral Preferences, Pamela Safford

Electronic Theses and Dissertations

This thesis investigates the optimal ex-ante mix of self-protection and self-insurance technologies employed to reduce the risk of biological invaders in the presence of exogenous variables within the probability and damage functions. This is accomplished by using a theoretical endogenous risk model that extends previously developed frameworks. This thesis contributes to the previous work in two ways. (1) Employing a general framework with simultaneous decision making over self-protection and self-insurance, this thesis analyzes how each parameter including income, the costs of each activity, an exogenous factor that affects only the probability of an invasion, and a separate exogenous factor that …

Affordances In The Design Of Virtual Environments, David Charles Gross Jan 2004

Affordances In The Design Of Virtual Environments, David Charles Gross

Electronic Theses and Dissertations

Human-computer interaction design principles largely focus on static representations and have yet to fully incorporate theories of perception appropriate for the dynamic multimodal interactions inherent to virtual environment (VE) interaction. Theories of direct perception, in particular affordance theory, may prove particularly relevant to enhancing VE interaction design. The present research constructs a conceptual model of how affordances are realized in the natural world and how lack of sensory stimuli may lead to realization failures in virtual environments. Implications of the model were empirically investigated by examining three affordances: passability, catchability, and flyability. The experimental design involved four factors for each …

Possible Use Of P20 Antigen In Serodiagnosis Of Inflammatory Bowel Disease, Shinchieh Yang Jan 2004

Possible Use Of P20 Antigen In Serodiagnosis Of Inflammatory Bowel Disease, Shinchieh Yang

Electronic Theses and Dissertations

Crohn's disease (CD) is an idiopathic, chronic, relapsing inflammatory disorder, which is most commonly involved terminal ileum and colon. The incidence and prevalence of CD has dramatically increased during the last 50 years; however, the etiology and mechanism of this disorder remain unveiled. Besides genetic susceptibility, recent integrated researches investigated the role of environmental triggers such as microflora, measles viruses and mycobacteria in the pathogenesis of CD. The association between M. avium subsp paratuberculosis (MAP) and CD has been heightened because of clinical resemblance to Johne's disease (JD), a granulomatous enteritis in ruminants caused by MAP. Isolation of MAP from …

Assumption, William Hinton Jan 2004

Assumption, William Hinton

Electronic Theses and Dissertations

Assumption is the story of a slave named Nathan living in a racially hostile environment in antebellum and post-Civil War Louisiana. Assumption Parish was the kind of place where slaves were whipped frequently, where disease and rustic living were the normal course of life, where the swamp, with all its savage foreboding, loomed nearby. It was a place, Nathan discovered, that traded in men's spirits, breaking them little by little for purposes that were difficult for him to comprehend. Like many slaves of his time, Nathan is raised without biological parents. His surrogate mother, Abbie, longs for the day when …

Exposure Matters: Examining The Physical And Psychological Health Impacts Of Toxic Contamination Using Gis And Survey Data, Christine A. Bevc

Electronic Theses and Dissertations

In the late 1970s and early 1980s, the grassroots environmental movement brought national attention to the issues related to inequities in environmental quality. Previous research addressing these environmental inequities has progressively increased and advanced methodologically. However, the arguments and focus have been primarily limited to examining the socio-demographics in an ongoing debate of race and class. This thesis extends past the methodological stalemate focusing on the application of Geographic Information Systems (GIS) using survey data in an environmental justice case study of a community in south Florida. This approach examines the social, health and environmental impacts of a Superfund site …

Genetic Analysis Of Rhoa Signaling During Epithelial Morphogenesis In Drosophila, Amanda Fitch Leppert Jan 2004

Genetic Analysis Of Rhoa Signaling During Epithelial Morphogenesis In Drosophila, Amanda Fitch Leppert

Electronic Theses and Dissertations

Epithelial morphogenesis is contingent upon cell shape changes. Cell shape changes are the driving force for the metamorphosis of the adult Drosophila leg from the leg imaginal disc precursor. Genetic analysis has identified several Drosophila genes involved in regulating cell shape changes during leg disc morphogenesis. These include members of the RhoA signaling pathway and the product of the Stubble-stubbloid (Sb-sbd) locus, a transmembrane serine protease. Mutations in the Sb-sbd gene interact genetically with the members of the RhoA signaling pathway, however the nature of the relationship between Sb-sbd serine protease activity and RhoA signaling is not understood.

Automatic Annotation Of Database Images For Query-By-Concept, Nualsawat Hiransakolwong Jan 2004

Automatic Annotation Of Database Images For Query-By-Concept, Nualsawat Hiransakolwong

Electronic Theses and Dissertations

As digital images become ubiquitous in many applications, the need for efficient and effective retrieval techniques is more demanding than ever. Query by Example (QBE) and Query by Concept (QBC) are among the most popular query models. The former model accepts example images as queries and searches for similar ones based on low-level features such as colors and textures. The latter model allows queries to be expressed in the form of high-level semantics or concept words, such as "boat" or "car," and finds images that match the specified concepts. Recent research has focused on the connections between these two models …
