United States Navy Fire Control Women Of The 1980s: Integrated Tribulations, Jo Nell Wildman
Browse all Theses and Dissertations
The Women’s Armed Service Act of 1948 limited women primarily to socially acceptable ratings in the clerical, medical and training fields. With the repeal of the Combat Exclusion Rule for women in 2013 and the opening of all ratings to any qualified person in 2016, today’s military women have opportunities unequal to those of the past. Between 1948 and 2016, policies regarding women fluctuated, opening and closing various nontraditional ratings and leaving women caught in the crossfire. The Navy’s Fire Controlman was one of those ratings, opening to women in 1972 and closing again in 1983. Approximately thirty women enlisted …

Goals can be described as the user's desired state of the agent and the world and are satisfied when the agent and the world are altered in such a way that the present state matches the desired state. For physical agents, they must act in the world to alter it in a series of individual atomic actions. Traditionally, agents use planning to create a chain of actions each of which altering the current world state and yielding a new one until the final action yields the desired goal state. Once this goal state has been achieved, the goal is said …

Seventy years after the first use of nuclear weapons in World War II, the proliferation of these apocalyptic munitions remains a key policy issue on the international stage. The available literature on nuclear proliferation suggests a strong correlation between the threat of rival a state seeking nuclear weapons and a state's own decision to pursue its own nuclear weapons. Regional rivals Argentina and Brazil both initiated nuclear weapons programs and were also developing nuclear delivery systems; however, these countries were able to step out of this dyadic proliferation spiral and renounced their nuclear weapons programs. Often assumed a success of …

The crystal structure, surface morphology, and ionic conductivity are systematically studied. LATP pellets are prepared using solid state reaction approach. The results indicate that calcine temperature has significant impacts on the phase impurity and sintering temperature and duration have more impacts on the grain size and porosity of LATP …
Interpretation Of A Seismic Reflection Survey And Geophysical Well Logs In Jay County, Indiana: Orientation And Composition Of A Carbonate Layer Below The Mount Simon Sandstone, Md Saiful Alam
Browse all Theses and Dissertations
In August 2017, a dynamite-sourced 2D seismic reflection survey was conducted along a gravel road northwest of Portland, Indiana. The main focus of the survey was to determine the orientation of a lithologic unit previously identified by Welder (2014) on a similar 2D seismic reflection survey in the same area. Drillers logs of two wells within this area identified a limestone layer below the Mt. Simon Sandstone, and a similar limestone layer was identified in a well drilled in Clark County, Ohio. As the focus of this study, this limestone layer will be informally named the `Votaw limestone'. The seismic …

My thesis seeks to understand if the Wehrmacht understood the Red Army's operational doctrine following the war. I will analyze both Red Army and Wehrmacht after action reports and memoirs created after the war to accomplish this. This analysis covers the Battle for Moscow, the Battle of Stalingrad, Operation Zitadelle, and ends with the destruction of the Wehrmacht's Army Group Center in Operation Bagration. This period represents the marked rise and decline of the Wehrmacht's martial supremacy in Russia. The comparison of Russian and German after action reports from this period exposes a weakness in German operational doctrine, which ultimately …

The overarching goal of this project is to develop novel neural motor decoders for prosthetic control. EMG decoders measure the activity from an intact but non-target muscle. Neural motor decoders transform the signal measured from the severed motor axons of the target muscle. A multi-scale, highly-realistic computer model of a spinal motor pool was developed (Allen & Elbasiouny, 2018) to serve as a computational platform for decoder development and testing. A firing rate-based algorithm was developed to transform the aggregate discharge of the motor pool into a command signal to control the simulated prosthetic MuJoCo hand. This algorithm was informed …

Browse all Theses and Dissertations
This thesis presents the design, implementation, and evaluation of an abstract-syntax-tree-oriented symbolic execution engine for the PHP programming language. As a symbolic execution engine, our system emulate the execution of a PHP program by assuming that all inputs are with symbolic rather than concrete values. While our system inherits the basic definition of symbolic execution, it fundamentally differs from existing symbolic execution implementations that mainly leverage intermediate representation (IRs) to operate. Specifically, our system directly takes the abstract syntax tree (AST) of a program as input and subsequently interprets this AST. Performing symbolic execution using AST offers unique advantages. First, …

Semantic And Structural Influences On Spatial Knowledge Acquisition, Robert B. May
Browse all Theses and Dissertations
Spatial memory for the layout of large-scale environments, configural spatial memory, has typically been construed as being very structured, using something like a metric coordinate system and using environmental objects to define that coordinate system. Inside of buildings, rectangular rooms have walls at right angles that have been considered to fulfill this role. However, the influence of non-spatial factors and considerations of relatively unstructured environments have not received much attention. Semantic organization was found to improve configural spatial memory for landmark objects in rooms with walls and it was independent of the structural relations among landmark objects (Colle & Reid, …

Regulation Of Microvesicle Particle Release In Keratinocytes, Azeezat Afolake Awoyemi
Browse all Theses and Dissertations
Microvesicle particles (MVPs) are produced from cellular membranes and are thought to mediate cell-cell communication, including in response to stressors such as UVB radiation and thermal burn injury. Previous studies have shown that stress-induced MVP release requires the platelet-activating factor (PAF) receptor in human keratinocytes and that pharmacological inhibition of acid sphingomyelinase (ASM) blocked this release. To validate a genetic role for ASM in MVP release, we used CRISPR-Cas9 gene silencing in human keratinocytes and primary fibroblasts derived from ASM-knockout mice. Though MVP release was partially blocked in ASM-deficient mouse fibroblasts, the inability to fully knockdown ASM in HaCaT cells …
Consequences Of Postsecondary Education Institution Policies And Practices: A Structural Model Of Tuition Costs, Student Financial Aid, Selectivity, Proximity, And Enrolled Undergraduate Students' Aggregate Capital, Aaron Michael Skira
Browse all Theses and Dissertations
For decades, U.S. higher education enrollments have been stratified with students from wealthier households consistently attending postsecondary institutions at higher rates than low-income students. The disparity in postsecondary participation rates by family income is a systemic issue (M. J. Bailey & Dynarski, 2011), meaning the phenomenon is the result of a combination of factors within society rather than one factor alone. Guided by a critical theory perspective and the assumptions behind Perna’s (2006) proposed conceptual model for student college choice research, the current study sought to examine the extent to which policies and practices at the postsecondary institution level may …

In recent times, social media platforms like Twitter have become more popular and people have become more interactive and responsive than before. People often react to every news in real-time and within no-time, the information spreads rapidly. Even with viral diseases like Zika, people tend to share their opinions and concerns on social media. This can be leveraged by the health officials to track the disease in real-time thereby reducing the time lag due to traditional surveys. A faster and accurate detection of the disease can allow health officials to understand people's opinion of the disease and take necessary precautions …

Too Long And Too Boring: The Effects Of Survey Length And Interest On Careless Responding, Cheyna Katherine Brower
Browse all Theses and Dissertations
Careless responding (CR), also called insufficient effort responding (IER), occurs when survey participants respond to items without regard to item content. The presence of careless responding threatens the validity of inferences made from self-report data (Huang et al., 2012; Huang et al., 2015). This study examines the effects of two proposed causes of careless responding (Mead & Craig, 2012): questionnaire length and participant disinterest. Specifically, I hypothesized that (a) questionnaire length is positively related to careless responding, (b) participant interest is negatively related to careless responding, and (c) questionnaire length has a weaker relationship with careless responding among participants who …

HSV-1 is a ubiquitous virus capable of causing lifelong latent infection. The virus contains a large double strand DNA genome covered by an icosahedral capsid. HSV-1 is a cytolytic virus which can cause a lethal infection. The virus possesses critical protein ICP0 which is capable of interfering with host cell signaling and eventually prevent cell apoptosis. Innate immunity plays a crucial role in defense against HSV-1 infection and macrophage plays a significant role in the innate immune system. Macrophage cells can alter their behavior depending upon certain stimuli and tissue environments. Naive macrophage (M0) cells can be polarized to a …

Keratinocytes and neurons cells are the main target for Herpes Simplex Virus Type 1 (HSV-1) invasion. Moreover, keratinocytes are the most abundant cell types in the epidermis layer in the skin. Therefore, they are the first cells to encounter HSV-1 in the primary infection. Next, the virus reaches the nerve endings and is transferred to neuronal cells as a result from the primary infection. In between these two events, innate immune cells including monocytes and macrophages response is activated and recruited to the infection site. In this study, keratinocytes (PAM-212) and murine macrophage (RAW 264.7) cell lines were utilized to …

The influence of surface effects on a hysteresis loop for single domain, ferromagnetic nanoparticles was examined. Theoretical equations were derived to describe the magnetic behavior of the domains and a MATLAB program was used to solve them. M-H curves were calculated for the case when a magnetic field is applied in the favorable magnetization direction (easy axis). In contrast, the calculations show there were no hysteresis loops when the magnetic field was applied perpendicular to the easy axis. Our studies showed how parameters of the surface such as a associated with saturation magnetization near the surface of nanoparticles and Ks …

The Asia Pacific power structure is facing numerous challenges. Scholarship demonstrates Japan has encountered arduous obstacles as it balances Chinese and North Korean activity. As Japan attempts to expand its military capabilities, polling data shows that defense policy has conflicted with Japan's citizens and neighboring countries. The focal point of these contentions is Article 9 of the Japanese constitution which restrains the Japanese military to self-defense purposes. Prime Minister Shinzo Abe has vowed to revise Article 9 by 2020. However, revising Article 9 is no simple task. Research demonstrates that for decades Japanese public opinion has been opposed to the …

HSV-1 causes a life-long infection in its host and has evolved multiple strategies to facilitate infection and evade the immune response. This virus has been found to enter cells by both endocytosis and fusion. The way the virus exploits endocytosis is not fully understood. Recent studies have uncovered roles of Rab GTPases, key regulators in intracellular membrane trafficking pathways, in distinct steps of the HSV-1 life cycle (Raza et al., 2018). This study will focus on analyzing the levels of the late endosomal regulator Rab7 expression in macrophages infected with HSV-1. Revealing the effect of virus on the levels of …

Three-dimensional (3D) simulation of patient-specific morphological models has been widely used to provide the hemodynamic information of individual patients, such as wall shear stress (WSS), oscillatory shear index (OSI), and flow patterns, etc. Since patient-specific morphological segment was only restricted locally, boundary conditions (BCs) are required to implement the CFD simulation. Direct measurements of the flow and pressure waveforms were often required as input BCs for 3D CFD simulations of patient-specific models. However, as the morphology develops, the feedback from this topological deformation may lead to BCs being altered, and hence without this feedback, the flow characteristics of the morphology …

In this paper, we establish the John-Stromberg inequality in certain anisotropic BMO spaces and apply the inequality to anisotropic Holder continuous function spaces. To achieve this goal, we define the median value, BMO space and sharp maximal function first. Secondly we constructed a family of continuously expanding rectangles and give a Calderon-Zygmund type decomposition. By using these tools, we establish the John-Stromberg inequality. Finally, an application to anisotropic Holder continuous function spaces is presented.

Previous fractal analyses of shoreline roughness have measured the fractal dimension of long segments of shoreline, e.g. Mandelbrot (1983) quantified the shoreline of the west coast of Britain and Feder (1988) quantified the shoreline of Norway. Consequently, changes in roughness along short segments are not captured by the analysis. In this study, the fractal dimension of the mainland shoreline of the contiguous United States has been measured in 125, 250, and 375 km segments using the box-counting method. The box counting method is based on the equation N = c x b where N is number of occupied boxes, C …
