Influences Of Display Design And Task Management Strategy On Situation Awareness, Performance, And Workload In Process Control Environments, James R. Bowden

Theses and Dissertations

Process control environments demand well informed high performing human monitors to maintain effectual control of multiple processes. Most research aims to satisfy this requirement through the evaluation of competing heuristic-based display design constructs. Contrary to that method, this study takes a novel approach by examining both factors internal and external to the human observer to identify where beneficial outcomes actually reside. External factors explore the underlying design construct attributes, while internal factors focus on the effect of operator task management strategy, age, and experience. Results from this study present several key findings relative to operator situation awareness, performance, and workload. …

A Decision Analysis Framework For Evaluation Of Helmet Mounted Display Alternatives For Fighter Aircraft, Matthew R. Dansereau

Theses and Dissertations

The promise of providing an intuitive and efficient information interface, while allowing the warfighter to perform other critical tasks such as targeting or aircraft control, has led to the growing popularity of Helmet Mounted Displays (HMDs) across the military landscape, especially combat aircraft. Though design and selection of competing systems is critical to optimized performance and safety, structured methods for the evaluation of HMDs are not often used in the acquisition community, leaving selection among alternative designs to the judgment of subject matter experts. However, technical decision-making has been shown to be flawed without the use of a structured decision …

Approximate Dynamic Programming For Military Resource Allocation, Carl R. Parson

Theses and Dissertations

This research considers the optimal allocation of weapons to a collection of targets with the objective of maximizing the value of destroyed targets. The weapon-target assignment (WTA) problem is a classic non-linear combinatorial optimization problem with an extensive history in operations research literature. The dynamic weapon target assignment (DWTA) problem aims to assign weapons optimally over time using the information gained to improve the outcome of their engagements. This research investigates various formulations of the DWTA problem and develops algorithms for their solution. Finally, an embedded optimization problem is introduced in which optimization of the multi-stage DWTA is used to …

Improving Non-Linear Approaches To Anomaly Detection, Class Separation, And Visualization, Todd J. Paciencia

Theses and Dissertations

Linear approaches for multivariate data analysis are popular due to their lower complexity, reduced computational time, and easier interpretation. In many cases, linear approaches produce adequate results; however, non-linear methods may generate more robust transformations, features, and decision boundaries. Of course, these nonlinear methods present their own unique challenges that often inhibit their use. In this research, improvements to existing non-linear techniques are investigated for the purposes of providing better, timely class separation and improved anomaly detection on various multivariate datasets, culminating in application to anomaly detection in hyperspectral imagery. Primarily, kernel-based methods are investigated, with some consideration towards other …

Optimal Collision Avoidance Trajectories For Unmanned/Remotely Piloted Aircraft, Nathan E. Smith

Theses and Dissertations

The post-911 environment has punctuated the force-multiplying capabilities that Remotely Piloted Aircraft (RPA) provides combatant commanders at all echelons on the battlefield. Not only have unmanned aircraft systems made near-revolutionary impacts on the battlefield, their utility and proliferation in law enforcement, homeland security, humanitarian operations, and commercial applications have likewise increased at a rapid rate. As such, under the Federal Aviation Administration (FAA) Modernization and Reform Act of 2012, the United States Congress tasked the FAA to provide for the safe integration of civil unmanned aircraft systems into the national airspace system (NAS) as soon as practicable, but not later …

Exploring Individual Differences In Workload Assessment, Danielle K. Boeke

Theses and Dissertations

Air Force missions continue to increase in complexity often imposing higher levels of task load from cognitive tasks on the operators. This increased task load manifests itself in increased cognitive workload and potentially derogated performance. While cognitive workload has been studied for decades, recent advances in objective workload models and physiology monitoring have the potential to provide a more robust understanding of workload, potentially allowing systems to adaptively employ automation to maintain operator peak performance. The current research sought to provide insight into the relationship between subjective workload, task performance, objective workload, and select physiology measures. Analysis of an existing …

Characterizing And Managing Intrusion Detection System (Ids) Alerts With Multi-Server/Multi-Priority Queuing Theory, Christopher C. Olsen

Theses and Dissertations

The DoD sets forth an objective to employ an active cyber defense capability to prevent intrusions onto DoD networks and systems. Intrusion Detection Systems (IDS) are a critical part of network defense architectures, but their alerts can be difficult to manage. This research applies Queuing Theory to the management of IDS alerts, seeking to answer how analysts and priority schemes effect alert processing performance. To characterize the effect of these two variables on queue wait times, a MATLAB simulation was developed to allow parametric analysis under two scenarios. The first varies the number of analysts and the second varies the …

Multi-Objective Trajectory Optimization Of A Hypersonic Reconnaissance Vehicle With Temperature Constraints, Tadeusz J. Masternak

Theses and Dissertations

Temperature-constrained optimal trajectories for a scramjet-based hypersonic reconnaissance vehicle were generated by developing an optimal control formulation and solving it using a variable order Gauss-Radau quadrature collocation method. The vehicle was assumed to be an air-breathing reconnaissance aircraft that has specified takeoff/landing locations, airborne refueling constraints, specified no-fly zones, and specified targets for sensor data collections. The aircraft model included fight dynamics, aerodynamics, and thermal constraints. This model was incorporated into an optimal control formulation that includes constraints on both the vehicle as well as mission parameters, such as avoidance of no-fly zones and coverage of high-value targets. Optimal trajectories …

Cloud-Induced Uncertainty For Visual Navigation, Alyssa N. Gutierrez

Theses and Dissertations

This research addresses the numerical distortion of features due to the presence of clouds in an image. The research aims to quantify the probability of a mismatch between two features in a single image, which will describe the likelihood that a visual navigation system incorrectly tracks a feature throughout an image sequence, leading to position miscalculations. First, an algorithm is developed for calculating transparency of clouds in images at the pixel level. The algorithm determines transparency based on the distance between each pixel color and the average pixel color of the clouds. The algorithm is used to create a dataset …

Hot Streak Characterization In Serpentine Exhaust Nozzles, Darrell S. Crowe

Theses and Dissertations

Modern aircraft of the United States Air Force face increasingly demanding cost, weight, and survivability requirements. Serpentine exhaust nozzles within an embedded engine allow a weapon system to fulfill mission survivability requirements by providing denial of direct line-of-sight into the high-temperature components of the engine. Recently, aircraft have experienced material degradation and failure along the aft deck due to extreme thermal loading. Failure has occurred in specific regions along the aft deck where concentrations of hot gas have come in contact with the surface causing hot streaks. The prevention of these failures will be aided by the accurate prediction of …

Using Data Mining To Determine The Impact Continuity Of Care Has On The Air Force’S Healthcare System, David F. Wade

Theses and Dissertations

Department of Defense (DoD) healthcare is one of the largest contributors to the DoD budget. In recent years, the cost of the DoD healthcare system has risen at an exponential rate. Much research has been conducted on the impacts that continuity of care has on both improving the quality of patient care and on reducing healthcare costs in the private sector. The DoD has attempted to take a similar approach with regards to healthcare continuity as a means to reduce healthcare costs. This research investigates whether continuity of care influences costs and a military member's availability to perform duties. Specifically, …

Combined Effect Of Hot Extrusion And Heat Treatment On The Mechanical Behavior Of 7055 Aa Processed Via Spray Metal Forming, J. M. Schreiber, Z. R. Omcikus, Timothy Eden, Mala Sharma, V. Champagne, S. N. Patankar

Faculty Journal Articles

The mechanical properties of 7xxx series alloys can be tailored by subjecting them to deformation pro- cessing and heat treatment. In the present study dealing with spray forming of 7055 AA, extrusion and heat treatment involving solutionizing followed by peak aging resulted in improved mechanical behavior. The strength and ductility obtained are comparable to that of extruded and heat treated as-cast 7055 AA (Mondal et al., 2011) [1]. Spray forming offers an alternate route to develop high strength aluminum alloys and the current study is an attempt that draws closer to the target value of 1GPa strength and 10% ductility …

School Choice As Means Of Social Change, Derryce Howzell

Communication & Leadership Dissertations and Theses

Parents and politicians have debated the topic of school choice for more than 20 years. The argument has changed slightly while also allowing more options to families. Rather than require students to be subject to de facto segregation, school choice offers the opportunity for students to interact with a more diverse population of students. As students interact with other students of diverse background they develop a better understanding of the world. Research suggests these students are also more likely to attend higher education and ultimately upgrade their socio-economic class. These interactions coupled with access to greater resources allow minority students …

“She Posted It On Facebook”: Mexican American Adolescents’ Experiences With Technology And Romantic Relationship Conflict, Heidi Adams Rueda, Megan Lindsay, Lela Rankin Williams

Social Work Faculty Publications

We examined experiences with technology and dating conflict among Mexican American (MA) adolescents (ages 15-17 years) using mixed qualitative methodologies. Focus groups, divided by three levels of acculturation and gender (N = 20), and videotaped observations of couples (N = 34), found that technology (i.e., cell phones, social media) afforded adolescents increased visibility of their partners’ day-to-day peer interactions. Feelings of romantic jealousy resulted in text message harassment and the expectation of immediate technology-facilitated contact. Females were more flirtatious as well as emotionally affected by jealousy resulting from social media sites, and males set rules regarding other-sex texting. …

Induction Of Callose Deposition In Tobacco (Nicotiana Tabacum) By Bacterial Lipopolysaccharide Pseudomonas Syringae Pv. Tabaci And Pseudomonas Syringae Pv. Glycinea, Pipit Marianingsih, Andi Salamah, Yuki Ichinose

Makara Journal of Science

Lipopolysaccharide (LPS) is a major component of outer-membrane gram-negative bacteria, and it can act as a Pathogen-Associated Molecular Pattern (PAMP) for perception of pathogens by plants. LPS can be recognized by plants, triggering certain plant defense-related responses, including callose deposition. This study investigated induction of callose deposition by bacterial LPS in tobacco. Tobacco leaves were infiltrated with 400 µg/mL and 800 µg/mL LPS extracted from Pseudomonas syringae pv. tabaci (Pta) and Pseudomonas syringae pv. glycinea (Pgl) and incubated for 24 h or 48 h. To detect callose deposition, tobacco leaves were cleared in lactophenol solution, stained with aniline blue, and …

Salt And Water Balance In The Land Crabs Of Christmas Island: A Review, Lm Turner

School of Biological and Marine Sciences

Work conducted on the land crabs of Christmas Island has advanced our knowledge of the ecophysiology of ion and water balance not only in terrestrial crabs, but across the Crustacea. For instance, studies undertaken on endemic Christmas Island species, such as Discoplax celeste, which is unique in its evolutionary position and ecology as a freshwater/land crab, have allowed us to increase our understanding of the mechanisms that have underpinned the evolution of these animals from the sea to the terrestrial environment. Recent studies have focused on understanding the neuroendocrine control of osmoregulation in terrestrial crabs on Christmas Island, with crustacean …

On The Front Foot: An Australian Health And Physical Education (Hpe) Perspective., Tj Lynch

Plymouth Institute of Education

When considering the theme ‘Towards building a new sport system’, it is important that as for any structure, there are strong foundations. Sport is a logical extension of a school’s physical education (PE) program (Commonwealth of Australia, 1992). Furthermore, research suggests that the optimum time for children to learn and refine their motor skills and to be introduced to positive PE experiences is during preschool and early primary school years. It is therefore argued that to build an ideal sport system, as suggested by the title, we need to ‘begin on the front foot’ through quality Health and Physical Education …

Molecular Targets Of Antihypertensive Peptides: Understanding The Mechanisms Of Action Based On The Pathophysiology Of Hypertension, Kaustav Majumder, Jianping Wu

Department of Food Science and Technology: Faculty Publications

There is growing interest in using functional foods or nutraceuticals for the prevention and treatment of hypertension or high blood pressure. Although numerous preventive and therapeutic pharmacological interventions are available on the market, unfortunately, many patients still suffer from poorly controlled hypertension. Furthermore, most pharmacological drugs, such as inhibitors of angiotensin-I converting enzyme (ACE), are often associated with significant adverse effects. Many bioactive food compounds have been characterized over the past decades that may contribute to the management of hypertension; for example, bioactive peptides derived from various food proteins with antihypertensive properties have gained a great deal of attention. Some …

An Inductive Sensor For Real Time Measurement Of Plantar Normal And Shear Forces Distribution, Li Du, X Zhu, J. Zhe

Mechanical Engineering Faculty Research

Goal: The objective of this article is to demonstrate a multiplexed inductive force sensor for simultaneously measuring normal force and shear forces on a foot. Methods: The sensor measures the normal force and shear forces by monitoring the inductance changes of three planar sensing coils. Resonance frequency division multiplexing was applied to signals from the multiple sensing coils, making it feasible to simultaneously measure the three forces (normal force, shear forces in x and y axis) on a foot using only one set of measurement electronics with high sensitivity and resolution. Results: The testing results of the prototype sensor have …

A Structured Reality, Jeremy Berke

Theses

Science has become an arbiter of truth in today's society. For example, think of how people say "It's a scientific fact" to imply that their position is infallible. As such, we should understand what science can tell about the universe. In this thesis I argue that science is telling us about the structure of reality, and that science only illuminates the relations among things, and not the things themselves.

A Sustainable Design Method Acting As An Innovation Tool, Jeremy Faludi

Dartmouth Scholarship

Product companies generally see sustainability as a burden limiting their design process, similar to cost or safety limits. A method for sustainable design was created, attempting to turn sustainability from a burden into an innovation tool with inherent business value. The method combines creative whole-systems thinking with quantitative sustainability metrics. It facilitates innovation by the creation of visual whole-system maps that encourage more thorough and more radical brainstorming. It facilitates sustainability by using quantitative measurements, such as lifecycle assessment or point-based certification systems, to set priorities and choose final designs. The method has been anecdotally tested in classes at four …

Tragedy Of The Regulatory Commons: Lightsquared And The Missing Spectrum Rights, Thomas W. Hazlett, Brent Skorup

Duke Law & Technology Review

The endemic underuse of radio spectrum constitutes a tragedy of the regulatory commons. Like other common interest tragedies, the outcome results from a legal or market structure that prevents economic actors from executing socially efficient bargains. In wireless markets, innovative applications often provoke claims by incumbent radio users that the new traffic will interfere with existing services. Sometimes these concerns are mitigated via market transactions, a la “Coasian bargaining.” Other times, however, solutions cannot be found even when social gains dominate the cost of spillovers. In the recent “LightSquared debacle,” such spectrum allocation failure played out. GPS interests that access …

Functional And Developmental Identification Of A Molecular Subtype Of Brain Serotonergic Neuron Specialized To Regulate Breathing Dynamics, Rachael D. Brust, Andrea E. Corcoran, George B. Richerson, Eugene Nattie, Susan M. Dymecki

Dartmouth Scholarship

Serotonergic neurons modulate behavioral and physiological responses from aggression and anxiety to breathing and thermoregulation. Disorders involving serotonin (5HT) dysregulation are commensurately heterogeneous and numerous. We hypothesized that this breadth in functionality derives in part from a developmentally determined substructure of distinct subtypes of 5HT neurons each specialized to modulate specific behaviors. By manipulating developmentally defined subgroups one by one chemogenetically, we find that the Egr2-Pet1 subgroup is specialized to drive increased ventilation in response to carbon dioxide elevation and acidosis. Furthermore, this subtype exhibits intrinsic chemosensitivity and modality-specific projections-increasing firing during hypercapnic acidosis and selectively projecting to respiratory chemosensory …
