To Be, Or Not To Be (Like My Sibling), That Is The Question: Examining Modeling And Differentiation Behaviors Among Siblings In Organized Youth Sport, Keith Vakafutu Osai

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Sibling relationships are typically the most enduring relationship in the family unit. A large body of research documents how sibling relationships occur in the context of the immediate family, how they impact behaviors such as risk-taking, how different cultures view siblings, and how similarities and differences among siblings can be attributed to genetics as well as shared and non-shared experiences. However, one relatively common family context in which sibling dynamics are less understood is organized youth sport. The present dissertation was designed to address multiplegaps in the present literature. This dissertation is comprised of two complementary studies. Study 1, guided …

This paper examines the themes of human perception and participation within the contemporary paradigm and relates the hallmarks of the major paradigm shift which occurred in the mid-20th century from a structural view of the world to a systems view. In this context, the author’s creative practice is described, outlining a methodology for working with the communication networks and interpersonal feedback loops that help to define our relationships to each other and to media since that paradigm shift. This research is framed within a larger field of inquiry into the impact of contemporary New Media Art as we experience it. …

The Responsibility Of Naval Line Officers In Determining Weapon System/Platforms, Samson Mikitarian

Naval War College Review

The Navy of today has adopted modern and systematized management techniques that are designed to receive and process large volumes of data from the fleet and other sources. As evidenced by the great number of studies, congressional inquires, and organizational changes., the Navy's entire process of research and development, equipment design, procurement, and operational maintenance has been taken under close scrutiny in an effort to achieve the most efficient system possible.

Application Memory Isolation On Ultra-Low-Power Mcus, Taylor Hardin, Ryan Scott, Patrick Proctor, Josiah Hester, Jacob Sorber, David Kotz

Dartmouth Scholarship

The proliferation of applications that handle sensitive user data on wearable platforms generates a critical need for embedded systems that offer strong security without sacrificing flexibility and long battery life. To secure sensitive information, such as health data, ultra-low-power wearables must isolate applications from each other and protect the underlying system from errant or malicious application code. These platforms typically use microcontrollers that lack sophisticated Memory Management Units (MMU). Some include a Memory Protection Unit (MPU), but current MPUs are inadequate to the task, leading platform developers to software-based memory-protection solutions. In this paper, we present our memory isolation technique, …

Over the last decades, an exponential growth in communication demand has been observed. Radio Frequency (RF) band has been one of the most used bandwidths for data transmission in the world. Given the influence and the continuous growth of communication technology, the RF spectrum is overpopulated. More efficient systems are necessary to meet the communication needs of this generation. A change to optical bandwidth is the most practical alternative to deal with the congestion of radio frequency.

The aim of this thesis is to present the features of Free Space Optical links with off-the-shelf components. A description of how these …

Building Teacher Self-Efficacy Through Administrator Feedback, Limary Trujillo Gutierrez

Dissertations

The study explored current site principals’ feedback practices that support or hinder teachers’ implementation of feedback, and identified site principal’s practices that encourage or interfere with teacher’s self-efficacy. Using qualitative interviews with site principals and teachers from two different districts and three different school sites, the study analyzed two major leadership practices: (a) an administrator’s ability to communicate effectively with teachers before, during, and after the feedback process, and (b) an administrator’s use of emotional intelligence when providing feedback. Data were separated into four feedback types (positive feedback, negative feedback, feedback and feedforward) and emotional intelligence traits (self-regulation, self-aware, empathy, …

Special Duty Officer For Systems Analysis: A Proposal, John S. Gubbings

Computer Science Faculty Research and Publications

When starting new and healthy habits or encouraging vigilance against returning to poor habits, a simple text message can be beneficial. Text messages also have the advantage of being easily accessible for lower-income populations spread over a rural area, who may not be able to afford smartphones with apps or data plans. Users benefit the most from text messages that are customized for them, but personalization requires time and effort on part of the user and the counselor. However, personalization that focuses on the cultural background of a pool of recipients, in addition to general personal preferences, can be a …

Management Of Asw Systems: A Look At Rotary Wing Asw, Stephen R. Arends

Naval War College Review

With Defense Department resources becoming increasingly scarce1 congressional scrutiny becoming even more intense, and the public becoming increasingly apathetic about defense, military decision makers must devote careful attention to ensuring that our combat capability is optimized for each defense dollar invested. This study looks at one portion of the triple threat environment of today's aircraft carrier and its integrated air wing, the subsurface threat to our surface Navy especially within the naval strike force outer zone area, i.e., 90 nautical miles.

Emergency Landing Of Small Unmanned Aerial Systems, Parker Lusk

Utah Space Grant Consortium

An algorithm for vision-based emergency landing of a multirotor is outlined. Using a recently developed real-time visual multiple target tracker, a potential fields-based obstacle avoidance algorithm is employed to find the “safest” part of a pre-determined landing site. A sliding mode controller for image-based visual servoing is designed that allows globally asymptotic tracking of a line of sight vector and the optical axis. The presented forced landing scheme allows for quick emergency landings to be performed in populated environments with moving ground obstacles.

An Examination Of Children’S Ministry Volunteer Development From Pastors And Laity In The Local Church, Kenneth Warren

Doctoral Dissertations and Projects

Developing children’s ministry volunteers in the local church is crucial to the sustenance of the body of Christ. Children’s ministry volunteers should be viewed as capable partners with both parents and church leaders in fulfilling the Great Commission. All volunteer ministries of the church matter, but those serving in children’s ministry have the unique opportunity to shape the lives of individuals who could serve the kingdom for a lifetime. Children’s ministry volunteer development is valuable because kingdom advancement hinges on lay ministry development as described in Ephesians 4:11–16. For this project, the researcher surveyed children’s ministry volunteers and pastors in …

Tracking The 10be-26al Source-Area Signal In Sediment-Routing Systems Of Arid Central Australia, Martin Struck, John D. Jansen, Toshiyuki Fujioka, Alexandru Tiberiu Codilean, David Fink, Reka H. Fulop, Klaus M. Wilcken, David M. Price, Steven Kotevski, L Keith Fifield, John Chappell

Faculty of Science, Medicine and Health - Papers: part A

Sediment-routing systems continuously transfer information and mass from eroding source areas to depositional sinks. Understanding how these systems alter environmental signals is critical when it comes to inferring source-area properties from the sedimentary record. We measure cosmogenic 10Be and 26Al along three large sediment-routing systems ( ∼  100 000 km2) in central Australia with the aim of tracking downstream variations in 10Be-26Al inventories and identifying the factors responsible for these variations. By comparing 56 new cosmogenic 10Be and 26Al measurements in stream sediments with matching data (n =  55) from source areas, we show that 10Be-26Al inventories in hillslope bedrock …

An Exploration Into The "Over The Wall Handling" Phenomenon Of Aid And Development Supply Chain Systems, Mark Edwards, Lee Styger

Sydney Business School - Papers

This paper provides some insight regarding the causes and implications of waste within Aid and Development programs and the impact on Aid effectiveness. In order to understand this better, a comparative case study analysis of three Aid and Development programs using a systems mapping process was used to identify major constraints within these supply chain systems. This work identified a complex matrix of nodal links within these systems that correspond to the flow of both funding and value creation. The findings point to Aid and Development supply chain systems being a closed loop system where much of the funding can …

Faculty of Engineering and Information Sciences - Papers: Part B

Solar-assisted heating, ventilation and air-conditioning (HVAC) systems are receiving increasing attention. This chapter presents the development of HVAC systems with integrated solar photovoltaic-thermal (PVT) collectors and phase change materials (PCMs) to reduce building energy consumption while providing satisfactory indoor thermal comfort. PVT collectors, which can generate both thermal energy and electricity simultaneously, are a promising technology for developing high-performance buildings. As solar energy is intermittent, the integration of phase change materials (PCMs) with PVTdriven HVAC systems can provide an opportunity to effectively utilise solar energy and maximise the performance of HVAC systems. The results showed that the coefficient of performance …

A Disturbance Observer-Based Robust Controller Design For Systems With Right Half Plane Zeros And Poles, Emre Sariyildiz, Ilhan Mutlu, Rahim Mutlu

Faculty of Engineering and Information Sciences - Papers: Part B

This paper analytically derives the bandwidth limitations of Disturbance Observer (DOB) when plants have Right Half Plane (RHP) zero(s) and pole(s). If the plant is non-minimum phase, then the bandwidth of DOB should be set at a lower value than its upper bound to improve the robust stability and performance. If the plant is unstable, then the bandwidth of DOB should be set at a higher value than its lower bound to achieve the robust stability. The upper and lower bounds are analytically derived by using Poisson integral formula. It is shown that the bandwidth limitation of DOB is directly …

Joint Transmission Power Control And Relay Cooperation For Wban Systems, Hongyun Zhang, Farzad Safaei, Le Chung Tran

Faculty of Engineering and Information Sciences - Papers: Part B

Improving transmission reliability is a crucial challenge for Wireless Body Area Networks (WBANs) because of the instability of channel conditions and the stringent Packet Loss Ratio (PLR) requirement for many WBANs applications. On the other hand, limited by the size of WBAN nodes, the energy consumption of WBAN nodes should be minimized. In this paper, we jointly consider transmission power control, dynamic slot scheduling and two-hop cooperative mechanism and propose an Autocorrelation-based Adaptive Transmission (AAT) scheme that achieves a better trade-off between transmission reliability and energy consumption for WBAN systems. The new scheme is designed to be compatible with IEEE …

Economic Operation Optimization Of Battery Energy Storage Systems In A Solar Rich Microgrid, Herath Pathiranage Asanga Priyankara Jayawardana, Massimo Fiorentini, Duane A. Robinson, Ashish P. Agalgaonkar

Faculty of Engineering and Information Sciences - Papers: Part B

The increasing trend of connecting local distributed generation units to the grid has unlocked new economic opportunities for owners. This is supported by the ongoing development of energy storage technologies, especially battery based systems. In practice, battery storage systems typically operate based on control algorithms where tariff structures and future generation and load profiles are not taken into account. This paper investigates the results of a case study for a microgrid using a proposed optimization model which minimizes cost by considering an import/export tariff structure. The effect of changing time resolution related to variations in demand and generation is examined, …

Generating Revenue At Airports In The Southeastern Coastal Region Of North Carolina, John Daniel Strong

Walden Dissertations and Doctoral Studies

Airports contribute about 5% of the gross domestic product and employ over 7 million people in the United States. The purpose of this qualitative multiple-case study was to explore the strategies that airport managers need to increase nonaeronautical revenue. A generic strategy does not exist to assist airport operators in generating operating income. Aeronautical revenue does not always provide sufficient funding for airport operations and existing research does not consistently provide effective strategies for all airports to generate revenue. The sample for this qualitative multiple case study consisted of 3 small commercial airport managers in the southeastern North Carolina coastal …

Health Behind Bars: Can Exploring The History Of Prison Health Systems Impact Future Policy?, Kathryn M. Weston, Louella R. Mccarthy, Isobelle Barrett Meyering, Stephen Hampton, Tobias Mackinnon

Faculty of Science, Medicine and Health - Papers: part A

The value of history is, indeed, not scientific but moral … it prepares us to live more humanely in the present, and to meet rather than to foretell, the future - Carl Becker. Becker's quote reminds us of the importance of revealing and understanding historical practices in order to influence actions in the future. There are compelling reasons for uncovering this history, in particular to better inform government policy makers and health advocates, and to address the impacts of growing community expectations to 'make the punishment fit the crime'.

Theory, Computation, And Modeling Of Cancerous Systems, Sameed Ahmed

Theses and Dissertations

This dissertation focuses on three projects. In Chapter 1, we derive and implement the compact implicit integration factor method for numerically solving partial differential equations. In Chapters 2 and 3, we generalize and analyze a mathematical model for the nonlinear growth kinetics of breast cancer stem cells. And in Chapter 4, we develop a novel mathematical model for the HER2 signaling pathway to understand and predict breast cancer treatment. Due to the high order spatial derivatives and stiff reactions, severe temporal stability constraints on the time step are generally required when developing numerical methods for solving high order partial differential …

Cyber-Physical Embedded Systems With Transient Supervisory Command And Control: A Framework For Validating Safety Response In Automated Collision Avoidance Systems, Daniel K. Trembley

Graduate Dissertations and Theses

The ability to design and engineer complex and dynamical Cyber-Physical Systems (CPS) requires a systematic view that requires a definition of level of automation intent for the system. Since CPS covers a diverse range of systemized implementations of smart and intelligent technologies networked within a system of systems (SoS), the terms “smart” and “intelligent” is frequently used in describing systems that perform complex operations with a reduced need of a human-agent. The difference between this research and most papers in publication on CPS is that most other research focuses on the performance of the CPS rather than on the correctness …
