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...

Making the Unconscious Unconscious : Reclaiming Microinteractions for People with Motor Disabilities

Creator:: Lazewatsky, Daniel A.
Abstract:: Numerous diseases and injuries can limit a person's ability to perform everyday tasks -- things like getting dressed, bathing, and eating. Anything that requires physical activity can be affected; even simple things like turning on the lights can become difficult or impossible. Until recently, the only way for a person...

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...

Toward Machine Learning-Enabled Adaptivity for Humorous Robots

Creator:: Gray, Carson C.
Abstract:: Social robots benefit from a sense of humor, which requires the ability to recognize and adapt to human responses during playful interactions. Past work on humorous robots has classified audience responses with audio-based and preliminary visual-based methods following the joke punchline. Building on this progress, we conducted a survey of...

Providing Informative Feedback for Learning in Tightly Coupled Multiagent Domains

Creator:: Rockefeller, Golden C.
Abstract:: Autonomous agents that sense, decide, act, and coordinate effectively with each other are critical in many real-world domains such as autonomous driving, search and rescue missions, air traffic management, and underwater or deep space exploration. All such domains share a key difficulty: though high-level mission goals are clear to system...

Design Optimization of a Structurally Flexible Wave Energy Converter with a Direct Search Algorithm

Creator:: Berrier, Austin S.
Abstract:: Several wave energy converter designs have been recently proposed that are made of flexible materials. Flexible devices are able to generate electricity by being stretched, and are intended to simplify deployment and maintenance concerns over existing wave energy devices. Due to the relative infancy of flexible wave energy converters, however,...

Mechanical engineering design across cultures : a method of designing for cultures

Creator:: Van Bossuyt, Douglas L.
Abstract:: Mechanical design is often based on formal methodologies such as Quality Function Deployment. Techniques to quantitatively account for attractability, sensory perception, and affective design have been successfully incorporated into these methods and are receiving growing acceptance across many industries. Although the adoption of these methods marks a large improvement for...

Identifying the Effects of Combustion Products, Turbulent Fluctuations, and Delivered Energy on Ignition Characteristics of Forced Ignition of Jet-A/air Mixtures

Creator:: Teope, Kaz I.
Abstract:: The operation of gas turbine engines depends on the reliable ignition of fuel/air mixtures. Gas turbine engines are commonly used as commercial and military aviation power plants. However, consistent ignition within gas turbine engines is still a problem, especially for more challenging operating conditions such as emergency operations. This work...

Development of Cu-based Thin Films for Optoelectronic Applications

Creator:: Angelos, Gregory S.
Abstract:: CIGS and CdTe based commercial thin-ﬁlm solar cells (TFSCs) require an absorber thickness greater than 2 µm and 4 µm, respectively, to adequately absorb the solar spectrum. To efficiently extract photoexcited electrons, these TFSCs require relatively defect-free absorbers with high-minority carrier mobility (> 100 cm2V−1s−1) and long lifetime (> 10...

Influence of subset size, shape and orientation on texture based digital image correlation

Creator:: Cui, Jianqing
Abstract:: Digital Image Correlation(DIC) is one of full-field strain measurement techniques devel- oped in recent decades, which has been well-demonstrated to conduct the mechanical properties study of solid materials, by collecting data using digital cameras. X-ray to- mography(CT) imaging helps the correlation techniques expanded to three dimensional investigation of materials, known...
