Vision-Aided Autonomous Precision Weapon Terminal Guidance Using A Tightly-Coupled Ins And Predictive Rendering Techniques, Jonathan W. Beich
Vision-Aided Autonomous Precision Weapon Terminal Guidance Using A Tightly-Coupled Ins And Predictive Rendering Techniques, Jonathan W. Beich
Theses and Dissertations
This thesis documents the development of the Vision-Aided Navigation using Statistical Predictive Rendering (VANSPR) algorithm which seeks to enhance the endgame navigation solution possible by inertial measurements alone. The eventual goal is a precision weapon that does not rely on GPS, functions autonomously, thrives in complex 3-D environments, and is impervious to jamming. The predictive rendering is performed by viewpoint manipulation of computer-generated of target objects. A navigation solution is determined by an Unscented Kalman Filter (UKF) which corrects positional errors by comparing camera images with a collection of statistically significant virtual images. Results indicate that the test algorithm is …
A Framework For The Measurement Of Simulated Behavior Performance, Christopher M. Cooper
A Framework For The Measurement Of Simulated Behavior Performance, Christopher M. Cooper
Theses and Dissertations
Recent development in video games, simulation, training, and robotics has seen a push for greater visual and behavioral realism. As the reliance on high fidelity models in the education, training, and simulation communities to provide information used for strategic and tactical decisions rises, the importance of accuracy and credibility of simulated behavior increases. Credibility is typically established through verification and validation techniques. Increased interest exists in bringing behavior realism to the same level as the visual. Thus far validation process for behavioral models is unclear. With real world behavior a major goal, this research investigates the validation problem and provides …
Adaptive Quality Of Service Engine With Dynamic Queue Control, James D. Haught
Adaptive Quality Of Service Engine With Dynamic Queue Control, James D. Haught
Theses and Dissertations
While the current routing and congestion control algorithms in use today are often sufficient for networks with relatively static topology, these algorithms may not be sufficient for military networks where a certain level of quality of service (QoS) needs to be achieved to complete a mission. Current networking technology limits a network's ability to adapt to changes and interactions in the network, often resulting in sub-optimal performance. This research investigates the use of queue size predictions to create a network controller to optimize computer networks. These queue size predictions are made possible through the use of Kalman filters to detect …
A Multispectral Bidirectional Reflectance Distribution Function Study Of Human Skin For Improved Dismount Detection, Bradley M. Koch
A Multispectral Bidirectional Reflectance Distribution Function Study Of Human Skin For Improved Dismount Detection, Bradley M. Koch
Theses and Dissertations
In 2008, the Sensors Exploitation Research Group at the Air Force Institute of Technology began using spectral properties of skin for the detection and classification of humans. Since then a multispectral skin detection system was developed to exploit the optical properties of human skin at wavelengths in the visible and near infrared region of the electromagnetic spectrum. A rules-based detector, analyzing an image spectrally, currently bases its skin pixel selection criteria on a diffuse skin reflectance model. However, when observing skin in direct view of the sun, a glint of light off skin is common and indicates specularity. The areas …
Routing Uavs To Co-Optimize Mission Effectiveness And Network Performance With Dynamic Programming, Spenser D. Lee
Routing Uavs To Co-Optimize Mission Effectiveness And Network Performance With Dynamic Programming, Spenser D. Lee
Theses and Dissertations
In support of the Air Force Research Laboratory's (AFRL) vision of the layered sensing operations center, command and control intelligence surveillance and reconnaissance (C2ISR) more focus must be placed on architectures that support information systems, rather than just the information systems themselves. By extending the role of UAVs beyond simply intelligence, surveillance, and reconnaissance (ISR) operations and into a dual-role with networking operations we can better utilize our information assets. To achieve the goal of dual-role UAVs, a concrete approach to planning must be taken. This research defines a mathematical model and a non-trivial deterministic algorithmic approach to determining UAV …

Multiple Integrated Navigation Sensors For Improving Occupancy Grid Fastslam, Christopher P. Weyers
Multiple Integrated Navigation Sensors For Improving Occupancy Grid Fastslam, Christopher P. Weyers
Theses and Dissertations
An autonomous vehicle must accurately observe its location within the environment to interact with objects and accomplish its mission. When its environment is unknown, the vehicle must construct a map detailing its surroundings while using it to maintain an accurate location. Such a vehicle is faced with the circularly defined Simultaneous Localization and Mapping (SLAM) problem. However difficult, SLAM is a critical component of autonomous vehicle exploration with applications to search and rescue. To current knowledge, this research presents the first SLAM solution to integrate stereo cameras, inertial measurements, and vehicle odometry into a Multiple Integrated Navigation Sensor (MINS) path. …
Immediate And Delayed Drug Therapy Effects On Low Dose Sarin Exposed Mice Myocardial Performance, Joshua T. Miller
Immediate And Delayed Drug Therapy Effects On Low Dose Sarin Exposed Mice Myocardial Performance, Joshua T. Miller
Theses and Dissertations
Recent studies have shown that a single asymptomatic dose exposure to the nerve agent sarin can lead to long term cardiac dysfunction. This study looked at immediate and delayed treatment therapies post exposure on cardiac function. The mice were studied using electrocardiography (QTc, STc, and Tc intervals) and histological techniques (hematoxylin and eosin staining and brain natriuretic peptide (BNP) staining). Male C57BL/6J mice were injected with sarin (0.4LD50) and studied up to 11 weeks. Mice which were given a single dose of the nerve agent treatment atropine/2PAMCL, showed significantly higher cell size and BNP levels than the control (p = …

There is a threat that a terrorist or terrorist organization will use access to the US food supply to kill or sicken Americans by contaminating imported food products from Mexico. The food that Americans eat is coming more and more often from foreign countries such as Mexico. Foodborne diseases infect nearly fifty million people in the US each year, resulting in over three thousand deaths. There are many terrorist organizations that would like to deliberately contaminate American food. Drug cartels and terrorist organizations currently operate in Mexico, one of the leading food importers into the US. The purpose of this …
Modeling Of Bacillus Spores: Inactivation And Outgrowth, Alexis X. Hurst
Modeling Of Bacillus Spores: Inactivation And Outgrowth, Alexis X. Hurst
Theses and Dissertations
This research models and analyzes the thermochemical damage produced in Bacillus spores by short, high-temperature exposures as well the repair process within damaged Bacillus spores. Thermochemical damage in spores is significantly due to reaction with water, hydrolysis reactions. Applying heat to the spore causes absorbed and chemically bound water molecules become mobile within the spore. These mobile water molecules react by hydrolysis reactions to degrade DNA and enzyme molecules in the spore. In order to survive the thermal inactivation, the spore must repair the damaged DNA during spore germination. The DNA repair process, as well as other germination functions, is …

A Novel Use Of Digoxin Immune Fab Fragment In Identification And Isolation Of An Endogenous Digitalis-Like Factor Found In Preeclampsia, Moana Lee Hopoate-Sitake
Theses and Dissertations
The mechanisms mediating the hypertension of preeclampsia (PE) are unclear. Endogenous digitalis-like factors (EDLFs) are specific sodium pump (SP) inhibitors implicated in essential and experimental hypertension, but they have not been fully explored in the setting of PE. This study uses a digoxin antibody Fab fragment to address the question of whether such factors are present and increased in PE, to investigate a possible treatment of PE, and to isolate and characterize all EDLFs present in PE. Sera and placenta from women with PE did show a significant increase in SP inhibition in comparison to women with normal pregnancy and …
The Functions Of Guilt And Shame In Juan José Millás' El Mundo And My Olive-Green Fridge And I: The Posthuman Identity In El Púgil, Constantin Cristian Icleanu
The Functions Of Guilt And Shame In Juan José Millás' El Mundo And My Olive-Green Fridge And I: The Posthuman Identity In El Púgil, Constantin Cristian Icleanu
Theses and Dissertations
In his celebrated 2007 novel El mundo, Juan José Millás tells the story of the development of Juanjo, a simulacrum of himself, and describes a series of negative developments that the protagonist faces in his childhood. While much has been written about Millás and the “testimonial realism” of his literary generation, little has been written about the psychological factors that influence his characters. In this paper I analyze Juanjo's development as understood from the gradation of guilt to shame, depression, and later suicidal thoughts. Because Juanjo is not able to find an appropriate mechanism of release for his guilt, …
Portrayals Of Relational Aggression In Popular Teen Movies: 1980-2009, Halie Ann Foell Stout
Portrayals Of Relational Aggression In Popular Teen Movies: 1980-2009, Halie Ann Foell Stout
Theses and Dissertations
The media is littered with various portrayals of aggression. This aggression has been shown to influence the attitudes, beliefs, and subsequent behaviors of its viewers (Bushman & Anderson, 2001). Relational aggression is a newer concern for researchers and has become more prevalent in recent research. Relational aggression is prevalent in the lives of adolescents. Using social cognitive theory (Bandura 2002), information processing theory (Huesmann, 1988), and the general aggression model (Anderson & Bushman, 2002) to justify how adolescents might be developing these relationally aggressive behaviors, this study seeks to expand the literature by evaluating the portrayals of relational aggression in …
Evolution And Emergence Of The Hinterland In The Active Banda Arc-Continent Collision: Insights From The Metamorphic Rocks And Coral Terraces Of Kisar, Indonesia, Jonathan R. Major
Evolution And Emergence Of The Hinterland In The Active Banda Arc-Continent Collision: Insights From The Metamorphic Rocks And Coral Terraces Of Kisar, Indonesia, Jonathan R. Major
Theses and Dissertations
Coral terrace surveys and U-series ages of coral and mollusk shells yield a surface uplift rate of ~0.6 m/ka for Kisar Island. The small island is located NE of Timor in the active Banda Arc of Indonesia. Based on this rate, Kisar first emerged from the ocean as recently as ~450 ka. Terrace surveys show warping that follows a pattern of east-west striking folds, which are along strike of thrust-related folds of similar wavelength imaged by a seismic reflection profile just offshore. This deformation shows that the emergence of Kisar can be attributed to forearc closure along the south-dipping Kisar …
Emulating Gossip Girl: Aggressive And Prosocial Material In Adolescent Novels And Associations With Behavior, Laura Ann Stockdale
Emulating Gossip Girl: Aggressive And Prosocial Material In Adolescent Novels And Associations With Behavior, Laura Ann Stockdale
Theses and Dissertations
Decades of researchers have found that exposure to aggressive content in multiple forms of media is associated with both physically (Bushman & Anderson, 2001) and relationally (Coyne, Nelson, Graham-Kevan, Keister, & Grant, 2010) aggressive behavior. Similarly, other researchers have found that exposure to prosocial content in multiple forms of media is associated with increased prosocial behavior (Mares & Underwood, 2008). While these associations have been studied in a variety of media, books as a form of media have received less research attention. The current study examined the associations between the content of adolescents' favorite novels and their normative beliefs about …

The individual performance of each subject was compared to the age- and gender-matched typical peers with …
Letting Go And The Silence That Remains: The Effects Of Translating Point-Of-View From Text To Film In The Remains Of The Day And Never Let Me Go, Jennifer L. Price
Letting Go And The Silence That Remains: The Effects Of Translating Point-Of-View From Text To Film In The Remains Of The Day And Never Let Me Go, Jennifer L. Price
Theses and Dissertations
Kazuo Ishiguro's novels The Remains of the Day and Never Let Me Go exhibit many of the same characteristics as his other works. Out of all of those works, however, only these two novels have been adapted to film as of yet. Because of Ishiguro's reliance on first-person narration and point-of-view his novels are particularly more problematic to adapt to screen. This phenomenon is partially due to the audio-visually dependent medium of film and the camera lens' limitations when it comes to exhibiting character interiority. Therefore, the effect of the translation to screen for both of these films is a …

Identification And Characterization Of Low Ph-Triggered Conformational Changes In The Herpes Simplex Virus Glycoprotein B, Stephen Dollery
Identification And Characterization Of Low Ph-Triggered Conformational Changes In The Herpes Simplex Virus Glycoprotein B, Stephen Dollery
Theses and Dissertations
Herpesviruses can enter host cells by pH-dependent endocytic pathways in a cell-specific manner. The role of pH in herpesvirus endocytosis is unclear. Herpes simplex virus (HSV) is a paradigm for virus membrane fusion via a complex of glycoproteins. HSV glycoproteins B, D and the heterodimer H-L are necessary and sufficient for membrane fusion. This work analyzes the structure and function of HSV glycoproteins B, D, and H-L at neutral pH, and at the physiological low-pH encountered during endocytic entry. It is demonstrated that mildly acidic low pH triggers specific conformational changes in HSV gB at a pH of 5.7 to …
Fused, Lauren Cifranic
Fused, Lauren Cifranic
Theses and Dissertations
I use encaustic, wire, and oil paint on wooden boxes and panels. I am interested in the process of layering media. These forms evolve as previous marks are concealed, added to, and concealed again while intuitively creating forms. With this body of work I explore confinement and freedom. Therefore, some of the shapes and forms seem contained while others appear to break away from their boundaries.
Manufacturing And Evaluation Of A Biologically Inspired Engineered Mav Wing Compared To The Manduca Sexta Wing Under Simulated Flapping Conditions, Nathanial E. Deleon
Manufacturing And Evaluation Of A Biologically Inspired Engineered Mav Wing Compared To The Manduca Sexta Wing Under Simulated Flapping Conditions, Nathanial E. Deleon
Theses and Dissertations
In recent years, researchers have expressed a vested interest in the concepts surrounding flapping wing micro air vehicles (FWMAVs) that are capable of both range and complex maneuvering. Most research in this arena has found itself concentrated on topics such as flapping dynamics and the associated fluid-structure interactions inherent in the motion, however there still remains myriad questions concerning the structural qualities intrinsic to the wings themselves. Using nature as the template for design, FWMAV wings were constructed using carbon fiber and Kapton and tested under simplified flapping conditions by analyzing frozen' digital images of the deformed wing by methods …
Thermodynamic, Sulfide, Redox Potential, And Ph Effects On Syngas Fermentation, Peng Hu
Thermodynamic, Sulfide, Redox Potential, And Ph Effects On Syngas Fermentation, Peng Hu
Theses and Dissertations
Recently, work in ethanol production is exploring the fermentation of syngas (primarily CO, CO2, and H2) following gasification of cellulosic biomass. The syngas fermentation by clostridium microbes utilizes the Wood-Ljungdahl metabolic pathway. Along this pathway, the intermediate Acetyl-CoA typically diverges to produce ethanol, acetic acid, and/or cell mass. To develop strategies for process optimization, a thermodynamic analysis was conducted that provided a detailed understanding of the favorability of the reactions along the metabolic pathway. Thermodynamic analysis provided identification of potentially limiting steps. Once these limiting reactions were identified, further thermodynamic analysis provided additional insights into the ways in which reaction …

Species Trees And Species Delimitation With Multilocus Data And Coalescent-Based Methods: Resolving The Speciation History Of The Liolaemus Darwinii Group (Squamata, Tropiduridae), Arley Camargo Bentaberry
Theses and Dissertations
The inference of species boundaries and phylogenetic relationships are fundamental for evolutionary, ecological, and conservation studies. The resolution of species boundaries and the inference of phylogenetic relationships among species are required to define the units of analysis and to find the most closely related units for evaluating alternative models of speciation. I highlight lizards as model organisms for ecological and evolutionary studies, emphasizing their contributions to advances in understanding linkages between phylogeography and speciation. In this dissertation, I focus on the phylogenetic relationships of the lizards in the Liolaemus darwinii group, and the species boundaries of a nested clade within …

Studies In Organic Synthesis: Part I: Total Synthesis Of Plakortethers F And G Part Ii: Carbon-Hydrogen Insertion On Diazosulfones And Diazosulfonates, Jinu Philip John
Theses and Dissertations
This work consists of two independent studies. The first part of the dissertation focuses on the total synthesis of two marine based natural products, Plakortether F and G which represent a class of non-peroxide derivatives of Plakortin related metabolites that are isolated from the Caribbean sponge Plakortis simplex. The selective cytotoxic activity of Plakortethers against the RAW 264-7 cell line (murine macrophage) makes them promising candidates for biological studies. A strategy utilizing desymmetrization of a C2 symmetric intermediate was proposed and demonstrated to be effective for the synthesis of the core of Plakortethers. Initially, the symmetric intermediate could only be …
