Functional analysis to inform early design decisions for novel systems with substantial operations and maintenance costs

Creator:: Algarra, Nathan
Abstract:: Long field-life systems are those for which operational, as opposed to capital, expenditures dominate the life time cost of the system. In established product categories, operational experience and historical maintenance data allows engineers to make informed decisions influencing maintenance during the early design stages when design changes are at their...
Resource Type:: Masters Thesis

Incidental Sensor Networks for Human Mobility Detection

Creator:: Hoover, Sylvan
Abstract:: Transportation systems need to get better by moving ever more people while consuming ever fewer resources. To build better transportation systems, planners need an accurate understanding of how people exercise mobility and tools to apply that understanding to the transportation system. Such an understanding can come through the development of...

Lift Enhancement of Pliant Wings Through Bio-Mimicry

Creator:: Osterberg, Nathaniel Brent
Abstract:: Flexible aerodynamic surfaces have been shown to favorably influence flight characteristics at low Reynolds numbers by increasing lift, angle of attack at stall, and resistance to perturbation. The objective of the research presented within this thesis is to investigate the influence of two aspects of flight observed in biological flyers,...

A framework for integrating systems thinking into sustainable manufacturing

Creator:: Zhang, Hao
Abstract:: Improving the understanding the relations of sustainability behaviors in manufacturing systems and actively engaging with manufacturers (especially SMEs) in sustainability efforts is key to the long-term success of U.S. industry and the natural environment. This study addresses this urgent need by establishing a systemic approach for the design of costing...

Multi-objective Resilience Optimization of Interdependent Critical Infrastructure Networks

Creator:: Tiong, Achara
Abstract:: Critical Infrastructures (CIs) such as energy, water supply, telecommunications, and transportation are highly vulnerable to cascading failures due to their interdependent operations. A resilient network is crucial to withstand the impact of functionality loss in disruptive events. This research evaluates network expansion as a proactive resilience strategy in which new...

Computational Modeling of Smoldering Combustion in Wildland Fuels

Creator:: Jayasuriya, Waduge Jayani A.
Abstract:: Smoldering combustion in wildland fires is a critical phenomenon that needs in-depth study because it can initiate with weaker ignition sources, can persist for long periods, is difficult to suppress, and can transit to flaming combustion. Cellulose, hemicellulose, and lignin are the major organic constituents within biomass, in varying proportions...
Resource Type:: Dissertation

Developing a Methodology to Study the Effects of Adhesive Flow Penetration on Wood Adhesive Bond Performance by using Micro X-ray Computed Tomography (XCT) and Digital Volume Correlation (DVC)

Creator:: Ching, Daniel Jackson
Abstract:: Wood composites are an important renewable structural material which can be a net carbon sink when used in combination with sustainable forest management practices and high rates of log utilization. Adhesive bondlines are an essential part of composites, and for wood composites, they determine the moisture durability and mechanical performance...
Resource Type:: Dissertation

Exploring Intuitive Use

Creator:: Cairns, Tylee
Abstract:: The term "Intuitive use" has become a common phrase to describe interfaces and products, however it is rarely defined. Research regarding intuitive use is in its infancy, beginning primarily in 2003. With the development of new terms in Human Factors and Human-Computer Interaction, it is important for Designers and Users...
Resource Type:: Masters Thesis

Experimental study of two-phase gas-liquid flow in a microscale fractal-like branching flow network

Creator:: Kwak, Younghoon
Abstract:: Two-phase gas-liquid flows in microscale fractal-like branching channel flow networks were experimentally studied to assess the validity of existing void fraction correlations and flow regimes based on superficial gas and liquid velocities. Void fractions were assessed using two different methods. First, void fraction data were acquired using a High-Speed-High-Resolution (HSHR)...

Experimental Study of the Impact of Physical and Chemical Properties on Smoldering Combustion in Natural Fuels

Creator:: Smucker, Benjamin
Abstract:: Smoldering combustion in wildland fires is difficult to extinguish, can transition to flaming combustion, and produces a significant amount of pollutants. It is necessary to understand parameters controlling smoldering in order to help predict the smoldering behavior and potentially mitigate these hazards. The wide variety of natural fuels that occur...
