Achieving Transparency in Human-Collective Systems

Creator:: Roundtree, Karina A.
Abstract:: Collective robotic systems are biologically-inspired and exhibit behaviors found in spatial swarms (e.g., fish), colonies (e.g., ants), or a combination of both (e.g., bees). Collective robotic system popularity continues to increase due to their apparent global intelligence and emergent behaviors. Many applications can benefit from the incorporation of collectives, including...

Vortical Structures in Transition to Turbulence through Randomly Packed Porous Media: Scale, Energy, and Mixing Characteristics

Creator:: Mohammadi Ziazi, Reza
Abstract:: Vortical structures are the driving mechanism of transition to turbulence in porous media requiring adequately resolved observations along with analysis of the scale and energy of ﬂow within the pores. Of speciﬁc interest is to understand the vortex dynamics, energy, and turbulent mixing and transport properties in the scale of...

Development of a radial microlamination architecture for cylindrical microchannel arrays

Creator:: Vlieg, James H.
Abstract:: Microchannel arrays are being developed across a wide spectrum of microfluidic applications including blood processing, fuel cells and thermal management among many others. Typical arrays are based on a flat laminated architecture produced in a vacuum hot press (VHP) through solid-state diffusion bonding. Due to the cylindrical nature of certain...

Development of a Cartesian-grid-based solver for an oscillatory boundary layer over a rough wall

Creator:: Skitka, Joseph M.
Abstract:: Predominant models for predicting rates of sediment transport face acute shortcomings when applied to coastal boundary layers. This is due to a neglect of the web of stochastic variables governing the rate of sediment dislodgement. While stochastic models do exist, the parametric extent of their validity tends to be limited,...

Pre-Prototyping Framework: An Early Design Prototyping Methodology for Human-Centered Products and Workplaces

Creator:: Ahmed, Salman
Abstract:: Prototyping is a crucial step in product design and development, but it is also known as the highest sunk cost. The top 20 Research and Development (R&D) department spends 142 billion dollars, yet 40 to 46 percent of this money goes into developing products that cannot even make to the...

Mining Temporal Patterns for Prediction: A Mixed-Integer Programming Approach

Creator:: Mansourifard, Farzaneh
Abstract:: In the past two decades, the advancement in data collection and storage have led to the accumulation of complex datasets. Consequently, various industries have sought data-driven solutions to predict and detect anomalies. Temporal patterns have emerged as potential features in prediction models that could improve the performance of the identification...

Initial Designs for Improving Conversations for People Using Speech Synthesizers

Creator:: Nguyen, Duy M.
Abstract:: This thesis aims to determine the impact that Augmentative and Alternative Communication (AAC) devices have on social interactions, and then improves the AAC user experience through a user focus design process. AAC devices enable people who cannot speak to communicate with others. Unfortunately, they are tedious to use and make...

A numerical study of inertial flow features in moderate Reynolds number flow through packed beds of spheres

Creator:: Finn, Justin Richard
Abstract:: In this work, flow through synthetic arrangements of contacting spheres is studied as a model problem for porous media and packed bed type flows. Direct numerical simulations are performed for moderate pore Reynolds numbers in the range, 10 ≤ Re ≤ 600, where non-linear porescale flow features are known to...

Characterizing Linkages Between the Climate, Cryosphere, and Impacts on Run-of-River Hydropower in Data-Sparse Mountain Environments

Creator:: Mosier, Thomas M.
Abstract:: In many regions of the world, a significant portion of the surface water originates in mountain headwaters where the timing and magnitude of streamflow is largely dictated by the seasonal storage of precipitation as snowpack and long-term storage as glaciers. Accumulation, persistence, and melt of snow and ice are functions...

Design of Complex Engineered Systems Using Multiagent Coordination

Creator:: Soria Zurita, Nicolás Francisco
Abstract:: This thesis is the combination of two research publications working toward a unified strategy in which the design of complex engineered systems can be completed using a multiagent coordination approach. Current engineered system modeling techniques segment large complex models into multiple groups to be simulated independently. These methods restrict the...
