Toward Building A Social Robot With An Emotion-Based Internal Control, Andreas Marpaung

Electronic Theses and Dissertations

In this thesis, we aim at modeling some aspects of the functional role of emotions on an autonomous embodied agent. We begin by describing our robotic prototype, Cherry--a robot with the task of being a tour guide and an office assistant for the Computer Science Department at the University of Central Florida. Cherry did not have a formal emotion representation of internal states, but did have the ability to express emotions through her multimodal interface. The thesis presents the results of a survey we performed via our social informatics approach where we found that: (1) the idea of having emotions …

Cellular Immune Response And Gene Expression Profiling In Crohn's Dise, Claudia Romero

Electronic Theses and Dissertations

Despite the chronic debate in the etiology of crohn's disease (cd), a debilitating inflammatory bowel disease (ibd) closely related to ulcerative colitis (uc), an emerging interest in a possible mycobacterial role has been marked. Granuloma and pathologic manifestations in cd resemble aspects found in tuberculosis, leprosy and paratuberculosis. The latter, a chronic enteritis in cattle, goat, sheep and primates, which is similar to human enteritis, also known as cd, is caused by a fastidious, slow growing mycobacterium avium subspecies paratuberculosis (map). Due to the similarities between cd and paratuberculosis, a mycobacterial cause in cd has been proposed. Recent discovery of …

Characterization Of A Novel Interactor/Substrate For The Pro-Apoptotic Serine Protease Omi/Htra2, Valerie Anne Stratico

Electronic Theses and Dissertations

OmiHtrA2 is a highly conserved mammalian serine protease that belongs to the HtrA family of proteins. Omi shares homology with the bacterially expressed heat shock protease HtrA, which functions as a protease at higher temperatures and a chaperone at lower temperatures. Additionally, Omi shares sequence similarity with the mammalian homologs L56/HtrA1 and PRSP/HtrA3. Omi was first isolated as an interacting protein of Mxi2, an alternatively spliced form of the p38 stress-activated kinase, using a modified yeast two-hybrid system. Omi localizes in the mitochondria and in response to apoptotic stimuli the mature form of this protein translocates to the cytoplasm. In …

Polarimetric Characterization Of Random Electromagnetic Beams And Applications, Mircea Mujat

Electronic Theses and Dissertations

Polarimetry is one of the principal means of investigating the interaction of light with matter. Theoretical models and experimental techniques are presented in this dissertation for polarimetric characterization of random electromagnetic beams and of signatures of random media in different scattering regimes and configurations. The degree of polarization rather than the full description of the state of polarization is of interest in multiple scattering and free space propagation where the statistical nature and not the deterministic component of light bears the relevant information. A new interferometric technique for determining the degree of polarization by measuring the intensity fluctuations in a …

The New Man And The New Lad: Hegemonic Masculinities In Men's Lifestyle Magazines, Ashley Michelle Elmore

Electronic Theses and Dissertations

Men are bombarded with contradictory masculine imagery in the media. The perfect man must be aggressive but not violent, sensitive but not emotional, healthy, active and smart without being an idealist, overachiever or too bookish. Heterocentric male focused lifestyle magazines rival women’s magazines in number and availability. Some men look to these images as a tool by which to gauge their masculinity and learn their social role performance. This inquiry includes a content analysis of four major men's lifestyle magazines over a 12-month period in which four new masculinities: certitude, irony, new sexism and double voicing were critiqued. Elements of …

Quadratic Spatial Soliton Interactions, Ladislav Jankovic

Electronic Theses and Dissertations

Quadratic spatial soliton interactions were investigated in this Dissertation. The first part deals with characterizing the principal features of multi-soliton generation and soliton self-reflection. The second deals with two beam processes leading to soliton interactions and collisions. These subjects were investigated both theoretically and experimentally. The experiments were performed by using potassium niobate (KNBO3) and periodically poled potassium titanyl phosphate (KTP) crystals. These particular crystals were desirable for these experiments because of their large nonlinear coefficients and, more importantly, because the experiments could be performed under non-critical-phase-matching (NCPM) conditions. The single soliton generation measurements, performed on KNBO3 by launching the …

Stable Spatial Solitons In Semiconductor Optical Amplifiers, Erdem Ultanir

Electronic Theses and Dissertations

A spatial soliton is a shape invariant self guided beam of light or a self induced waveguide. Spatial solitons appear as a result of the balance of diffraction and nonlinear focusing in a system. They have been observed in many different conservative media in the last couple of years. Solitons are ubiquitous, because of the probability of using their interactions in optical data processing, communications etc. Up to now due to the power required to generate the solitons, and the response times of the soliton supporting media, these special waves of nature could not penetrate the applications arena. Semiconductors, with …

Dispersion-Managed Breathing-Mode Semiconductor Mode-Locked Ring Laser, Bojan Resan

Electronic Theses and Dissertations

A novel dispersion-managed breathing-mode semiconductor mode-locked ring laser is developed. The "breathing-mode" designation derives from the fact that intracavity pulses are alternately stretched and compressed as they circulate around the ring resonator. The pulses are stretched before entering the semiconductor gain medium to minimize the detrimental strong integrating self-phase modulation and to enable efficient pulse amplification. Subsequently compressed pulses facilitate bleaching the semiconductor saturable absorber. The intracavity pulse compression ratio is higher than 50. Down chirping when compared to up chirping allows broader mode-locked spectra and shorter pulse generation owing to temporal and spectral semiconductor gain dynamics. Pulses as short …

Towards Direct Writing Of 3-D Photonic Circuits Using Ultrafast Lasers, Arnaud Zoubir

Electronic Theses and Dissertations

The advent of ultrafast lasers has enabled micromachining schemes that cannot be achieved by other current techniques. Laser direct writing has emerged as one of the possible routes for fabrication of optical waveguides in transparent materials. In this thesis, the advantages and limitations of this technique are explored. Two extended-cavity ultrafast lasers were built and characterized as the laser sources for this study, with improved performance over existing systems. Waveguides are fabricated in oxide glass, chalcogenide glass, and polymers, these being the three major classes of materials for the telecommunication industry. Standard waveguide metrology is performed on the fabricated waveguides, …

Getting To The Pulp Of Haruki Murakami's Norwegian Wood: Translatability And The Role Of Popular Culture, Jacquelyn Zuromski

Electronic Theses and Dissertations

Haruki Murakami's Norwegian Wood (1987) veers from his favored detective-fiction genre by offering readers a 1960s coming-of-age romance, a story whose plot nonetheless spins around the protagonist seeking out his personal identity. The conflicts between Japanese tradition and modern, global perspectives are illustrated through the inclusion of popular culture elements such as music, literature and films. This thesis seeks to show how the novel's references to popular culture of the 1960s combine to help the protagonist establish an identity for himself as well as his place within the universal community. First, though, the project explores the impact of the translatability …

Women's Experiences With Distance Education, Jane Elizabeth Moody

Electronic Theses and Dissertations

This thesis examines issues that affect women in online learning, and discusses four women's particular experiences in the University of Central Florida's distance learning program. Online education involves aspects of support and communication that may affect women's learning experiences either positively or negatively. Distance learning may also allow women to pursue their education while still taking care of their families and outside work. In order to get a better idea of how distance learning impacts women, I discuss several studies that examine how distance learning affects women in particular. I identify three areas from this literature that seem to be …

Pseudomonas Aeruginosa 1244 Pilin Glycan: Surface Location And Induction Of Immune Response, Erica Sentgeorge Jewell

Electronic Theses and Dissertations

P. aeruginosa 1244 pilin is covalently modified with a carbohydrate moiety, which is structurally similar to the lipopolysaccharide (LPS) O-antigen repeating unit. Studies were conducted using transmission electron microscopy and scanning electron microscopy with the monoclonal glycan-specific antibody, 11.14, to determine the location of the glycan. It was found that the glycan is evenly distributed over the entire surface of the pilin fiber and not restricted to the tip. The immunogenicity of the pilin glycan was also studied. Rabbits were immunized with pure LPS-free pili to determine if the pili produce anti-LPS antibodies. The serum obtained from the rabbits was …

The emergence of the Women's Forum during the 1990's in Sierra Leone is analyzed using the political process model proposed by Douglas McAdam. The strength of the indigenous organizations, the political opportunities presented by the civil strife of the period and the emergence of insurgency consciousness on the part of the women of Sierra Leone were identified as significant in contributing to the success of the movement in bringing an end to the civil war and influencing the peace process to address women's issues, indicating the usefulness of this model in analyzing the emergence of social movements in the Sierra …

Vitellogenin Induction As A Biomarker For Environmental Estrogens In Xenopus Laevis, Jamie Skoloda

Electronic Theses and Dissertations

In oviparous vertebrates, estrogen stimulates the liver to produce vitellogenin. Vitellogenin induction is a useful biomarker for exposure to endocrine disruptors, specifically environmental estrogens. The objective of this project was to design in vivo bioassays for environmental estrogens based on induction of vitellogenin in male Xenopus laevis. Frogs were exposed to ethinyl-estradiol by injection or immersion for different times and doses, than vitellogenin induction was assessed. An ELISA was developed to measure serum vitellogenin. Additionally, a vitellogenin rt-PCR assay was developed using species-specific vitellogenin primers, to detect mRNA induction.

Interworking Methodologies For Dcom And Corba., Edwin Kraus

Electronic Theses and Dissertations

The DCOM and CORBA standards provide location-transparent access to network-resident software through language independent object interfaces. Although the two standards address similar problems, they do so in incompatible ways: DCOM clients cannot use CORBA objects, and CORBA clients cannot utilize DCOM objects, due to incompatible object system infrastructures.

This thesis investigates the performance of bridging tools to resolve the incompatibilities between DCOM and CORBA, in ways that allow clients to cross object system boundaries. Two kinds of tools were constructed and studied: tools that bind clients to services at compile time, and tools that support dynamic client-server bindings. Data developed …

Electronic Theses and Dissertations

Websites are being used by increasing numbers to target a market with a message unfiltered by the media. This content analysis examined the website front-screens for the members of the 108th United States Congress to determine if the photographic images displayed reinforced the media's stereotypical frame of female politicians. A total of 3,892 photographic images were captured from 540 websites and coded using the face-ism index. Overall, the results supported the face-ism theory. Images of females were cropped lower on their bodies than images of males. The face-ism effect was not supported until the number of people in the photograph …

A Sense Of Place., Neli Ilieva Ouzounova

Electronic Theses and Dissertations

Concerned with anxiety and displacement, the artist explores a sense of place within the self. Personal experiences are presented as an accumulation of fragmented symbols, textures and pattern. Symbolic imagery is being created, influenced by a devaluation of established norms and a reorganization of cultural identity. The individualÆs interaction and experience with the surrounding world affirms his idiosyncratic symbolism. The artwork is a visual language that through the use of disparate segments sets up the portrayal of the fragmented self and psychological journeys of the artist.

Individuals establish themselves in many ways, including gestures as part of expression. This expression …
