  • The Department of Meteorology is involved in research on the North American (Mexican) Monsoon in Arizona and the U.S. Southwest.
Meta-Analyses of the Effects of Standardized Handoff Protocols on Patient, Provider, and Organizational Outcomes

  • PI Joseph Keebler

    CO-I Elizabeth Lazzara

  • This meta-analysis attempts to understand the benefits of a structured communication process on patient, provider, and organizational outcomes. Studies have found that one of the most crucial points during a patient’s hospital stay is the transition of care between one or more providers, often referred to as a patient handoff. These brief interactions between providers are often especially vulnerable to communication breakdowns due to interruptions, omission of pertinent information by the sender or receiver of the information. To illustrate, upwards of 80% of severe, preventable medical errors have been attributed to miscommunication during handoffs. In other words, failures in communication during handoff are potentially responsible for the loss of hundreds of thousands of lives every year in the United States.
Micro Jet

  • PI Richard Beckwith

  • This research aims to provide opportunities for undergraduates to research and build a BD-5J and pursue a new method of aeronautical training.
Microfluidic Chip & Magnetic 3D Bioprinting Research

  • Breast and colon cancer are the leading causes of death in developed countries (e.g., U.S.) and are highly associated with numerous risk factors including genetics, diet, obesity, cigarette smoking, hypertension, stress, and spaceflight stressors. Despite advances in the diagnosis and treatment of cancer, the mortality rates are still high and the potential mechanisms driving the metastatic potential of the cancer cells are still not well characterized.

Mixing of a supercritical jet in a supercritical cross-flow

  • PI Neil Sullivan

    CO-I Mark Ricklick

  • This project is focused on the exploration and validation of numerical modeling techniques, for the simulation of supercritical jets in crossflow. 
Mobile Technology in Higher Education: An Extended Technology Acceptance Perspective

  • PI Dennis Pires

    PI Leila Halawi

  • The study provides an important theoretical framework for decision-making for educational institutions as they seek improvement in user acceptance of technology in the higher education setting. The study adds to the knowledge in the field of information technology by providing statistical research that uses path analysis to disentangle the various causal processes underlying the acceptance of technology in higher education. In this study, the research addresses the following question: Are the constructs of perceived resources, perceived ease of use, perceived usefulness, and attitude towards use significant predictors of educators’ acceptance of mobile technology in higher education as defined by actual use?

  • PI Alan Liu

Multi-Modal Sensor Fusion for ASV Situational Awareness

  • PI Eric Coyle

    CO-I Patrick Currier

  • An investigation into strategies and techniques for maritime object detection and classification using visual and spatial data with an emphasis on sensor fusion.
Multirotor Vector Control User Interface

  • PI Brent Terwilliger

    CO-I David Ison

    CO-I Dennis Vincenzi

  • This research represents the conceptual design of a multirotor control methodology to support observing areas outside direct line-of-sight (LOS) to locate objects of interest in tactical environments. It is hypothesized that design of an interface featuring vector/autopilot control would reduce operator attentional allocation, supporting the maintenance of localized situational awareness.
Multiscale Computational and Experimental Framework to Elucidate the Biomechanics of Infant Growth

  • PI Victor Huayamave

  • There is currently a lack of biomechanical quantification of growth and development because: (1) there is no generic musculoskeletal infant model, and (2) the lack of infant data in the literature.

Nanoscale Design of Interfacial Kinematics in Composite Manufacturing

  • PI Sirish Namilae

    CO-I Marwan Al-Haik

  • This NSF-funded research will elucidate the role of interfacial kinematics and energetics in the evolution of inter-ply interfaces in composite structures during manufacturing. The research team will develop a novel experimental method for in-situ characterization of surface and interface deformations during composite processing, utilizing a customized commercial composite autoclave with a digital image correlation system. The surface strain and displacement measurements will be combined with ex-situ X-ray tomography and thermal characterization to map the interfacial thermomechanical response as a function of design and processing parameters. Additionally, the interfacial behavior will be engineered through the rapid and controlled growth of ZnO nanowires on carbon fibers to create a nanoscale interfacial component that increases the fiber bending resistance and creates an interlocking effect at the interfaces to mitigate defects propagation. The experimental research will be complemented by molecular dynamics simulations of the sliding of amorphous polymer interfaces and mesoscale simulation of flow in porous media. This comprehensive approach of in-situ characterization, interface design, and modeling will lead to a fundamental understanding of the ply movement during composite manufacturing and development of methods to reduce the occurrence of processing-induced defects.
