Measuring The Effectiveness Of Us Military Humanitarian Construction Projects Through Geospatial Analysis Of Public Opinion In Belize, Arthur Z. Dietrich
Theses and Dissertations
As part of broader US foreign policy efforts the Department of Defense (DoD) increasingly conducts complex operations which focus on efforts to influence local populations. These \hearts and minds" operations often include humanitarian and development construction projects. The wider impact on US foreign policy effort from the US military's participation in projects traditionally conducted by civilian agencies is not well understood. This research examined the effects on local public opinion from two US Air Force led \Operation New Horizons" Humanitarian and Civic Assistance (HCA) missions conducted in the nation of Belize in 2013 and 2014. The study specifically looked for …

Analysis Of Inpatient Hospital Staff Mental Workload By Means Of Discrete-Event Simulation, Erich W. Maxheimer
Theses and Dissertations
Many process improvement tools have been applied to the healthcare industry to improve safety and efficiency. However, nearly all of these tools have neglected to explicitly quantify mental workload of healthcare providers despite the consensus that it is related to human performance. This research uses the Improved Performance Research Integration Tool (IMPRINT), a discrete-event simulation (DES), to quantify mental workload. Specifically, this research examines staff members in an inpatient unit at the Wright-Patterson Medical Center to detect workload differences between staff, identify trends which lead to high workload demands, evaluate the influence of patient load on mental workload, and test …

Enhancing Students Learning And Assessment Through Positive Reinforcement, Philip Appiah-Kubi
Engineering Management and Systems Faculty Publications
Students’ understanding of class material, and knowledge retention are assessed through homework, exams, and a host of other methods. None of these forms of assessment is intrinsically paramount to the others; however, the benefits depend on how well they are used. A good assessment depends on the purpose and learning objectives, and one way of maximizing the benefits of assessment is to involve students in the assessment methodology. This paper evaluates the benefits of having students prepare some of the questions for their final exams. Generally, students put in more effort when they understand that they are in charge. Each …

System Safety Modeling Of Alternative Geofencing Configurations For Small Uas, James T. Luxhoj
International Journal of Aviation, Aeronautics, and Aerospace
As is well known, the integration of small Unmanned Aircraft Systems (sUAS) or “drones” into the National Airspace System (NAS) has captured significant industry, academic, regulatory and media attention. For sUAS that typically fly low and slow, the possibility of a mid-air collision with a nearby general aviation aircraft needs to be studied from a system safety perspective to identify possible hazards and to assess mitigations. The Aviation System Risk Model (ASRM) is a first-generation socio-technical model that uses a Bayesian Belief Network (BBN) methodology to integrate possible hazards to assess a non-linear safety risk metric. Using inductive logic, the …

Development Of An Autonomous Robotic Mushroom Harvester, Nikita Alexeevich Kuchinskiy
Electronic Thesis and Dissertation Repository
The process of development of a new robot is one of the modern technological arts. This process involves multiple complex steps and recursive approach. In this project, a solution for automatic harvesting of mushrooms is developed. In order to design an effective solution, it is necessary to explore and take into consideration the limitations of grasping very soft and fragile objects (particularly mushrooms). We will elaborate several strategies of picking and analyze each strategy to formulate the design requirements, develop a solution, and finally, evaluate the efficiency of the proposed solution in actual farm conditions for real mushrooms. The mushroom …

Wireless Network Neutrality: Technological Challenges And Policy Implications, Christopher S. Yoo
All Faculty Scholarship
One key aspect of the debate over network neutrality has been whether and how network neutrality should apply to wireless networks. The existing commentary has focused on the economics of wireless network neutrality, but to date a detailed analysis of how the technical aspects of wireless networks affect the implementation of network neutrality has yet to appear in the literature. As an initial matter, bad handoffs, local congestion, and the physics of wave propagation make wireless broadband networks significantly less reliable than fixed broadband networks. These technical differences require the network to manage dropped packets and congestion in a way …

Agricultural production in the United States is undergoing marked changes due to rapid shifts in consumer demands, input costs, and concerns for food safety and environmental impact. Agricultural production systems are comprised of multidimensional components and drivers that interact in complex ways to influence production sustainability. In a mixed-methods approach, we combine qualitative and quantitative data to develop and simulate a system dynamics model that explores the systemic interaction of these drivers on the economic, environmental and social sustainability of agricultural production. We then use this model to evaluate the role of each driver in determining the differences in sustainability …

Risk Attitudes And Global Infrastructure Technology Choices, Jessica Kaminsky, Jeffrey P. Walters
Faculty Publications - Biomedical, Mechanical, and Civil Engineering
Past research shows that Hofstede’s cultural dimension of uncertainty avoidance explains variance in nations’ technology choice for sanitation and electricity infrastructure construction. The uncertainty avoidance dimension describes the way that nations deal with ambiguity and uncertainty. This paper is part of a larger project that links that previous national scale research to the project level that is most relevant to the construction practice. As such, this paper reviews methods from the literature that measure individual risk attitudes, including issues of measurement and risk determinants. For example, this paper discusses paid real-stakes lotteries, general risk questions, and context specific risk questions. …

It is recognized that international water sector development work has issues with a lack of sustained positive outcomes. A large driver of this outcome is how NGOs work with communities to implement and then manage water services. Many NGOs tend to focus their efforts on improving their reach and organisational growth by continually engaging in new projects. This behaviour is largely driven by short-term donor funding models that reward extended coverage, leaving little focus on sustained outcomes. Similarly, community-based management (CBM) schemes often impede sustained services as a result of the community’s limited capacity to operate and maintain the technology. …

High-fidelity and computationally efficient energy forecasting models for building systems are needed to ensure optimal automatic operation, reduce energy consumption, and improve the building’s resilience capability to power disturbances. Various models have been developed to forecast building energy consumption. However, given buildings have different characteristics and operating conditions, model performance varies. Existing research has mainly taken a trial-and-error approach by developing multiple models and identifying the best performer for a specific building, or presumed one universal model form which is applied on different building cases. To the best of our knowledge, there does not exist a generalized system framework which …

With the rapid growth and integration in technology and information, the behavior and structure of complex systems presents escalating challenges. Complex systems are marked by high level of ambiguity, uncertainty, and emergence. These conditions impose challenges and difficulties for practitioners responsible to successfully manage and design complex systems. There is a fundamental need to have a cadre of individuals who are capable of dealing with increasingly complex systems and their problems. One response is Systems Thinking, which can provide a holistic thinking paradigm that opens new channels and opportunities to think differently about complex systems as a whole unit. This …

Engineering Management & Systems Engineering Faculty Publications
The purpose of this paper is to explore Complex System Governance (CSG) issues related to systemic analysis of acquisition systems. CSG is an emerging field focused on the design, execution, and evolution of the functions necessary to provide continued system performance (stability) in the midst of incessant turbulence and increasing complexity. Integral to this field is the necessity to engage systems to address behavior or performance that is inconsistent with that which is desired. Systemic analysis for CSG serves to examine a system to discover fundamental system issues (e.g. acquisition). Arguably, system acquisition has an unremarkable record of success, ranging …

As acquisition processes have become more complex, they appear to no longer be governable by traditional approaches. Missed budgets, delayed deliveries, and expensive canceled systems appear to becoming more prevalent. Numerous investigations have been conducted attempting to elicit the factors that prevented success. Those systems that succeed in terms of usability, budget, and delivery schedule are the rarity and often become case studies themselves as we try to extract the characteristics that differentiate success from failure. A different viewpoint is to look at the acquisition system from the perspective of Complex Systems Governance (CSG). Recent developments in the field of …

Energy is both vital and strategic element for a nation to sustain its fundamental activities like security, logistics, heating, etc. Countries sustain their energy demands through internal or external sources. In the case of not being able to maintain energy demands from their internal sources, they would need to import their requirements. Whenever they need to buy raw materials, they have to build terminals to process the raw material into the required form. The dependency on the imports may cause the importing country to weaken its advantage in international conflicts, unemployment, and welfare. Therefore, countries aim to mitigate dependence to …

Energy system models have become the main supporting tool for energy policy. Modern challenges in energy policy require energy systems models that integrate technical, environmental and societal aspects of the energy systems. In this paper, we introduce a conceptual model for an energy system model that specifies the relationships between social, technical, environmental, and economic aspects of an energy system. This conceptual model presented in the IDEF0 language will serve as a basis for a computational energy systems model. © 2016 The Authors.

Fundamentally, a system of systems is characterized by operational independence, managerial independence, evolutionary development, emergent behavior, and geographical distribution. However, value-wise, a system of systems should provide greater capability beyond that which individual systems can provide. Enabling this greater capability has to be purposely designed for and managed. In this paper, we argue that this is the primary role of the metasystem structure and its execution. A metasystem is a governing structure that provides coordination and integration of multiple systems, brought together to achieve overarching missions and functions beyond those of the constituent systems. This paper articulates the differences between …

Various meta-modeling techniques have been developed to replace computationally expensive simulation models. The performance of these meta-modeling techniques on different models is varied which makes existing model selection/recommendation approaches (e.g., trial-and-error, ensemble) problematic. To address these research gaps, we propose a general meta-modeling recommendation system using meta-learning which can automate the meta-modeling recommendation process by intelligently adapting the learning bias to problem characterizations. The proposed intelligent recommendation system includes four modules: (1) problem module, (2) meta-feature module which includes a comprehensive set of meta-features to characterize the geometrical properties of problems, (3) meta-learner module which compares the performance of instance-based …
