Predicting Pilot Misperception of Runway Excursion Risk Through Machine Learning Algorithms of Recorded Flight Data
PI Edwin Odisho
CO-I Dothang Truong
The research used predictive models to determine pilot misperception of runway excursion risk associated with unstable approaches. The Federal Aviation Administration defined runway excursion as a veer-off or overrun of the runway surface. The Federal Aviation Administration also defined a stable approach as an aircraft meeting the following criteria: (a) on target approach airspeed, (b) correct attitude, (c) landing configuration, (d) nominal descent angle/rate, and (e) on a straight flight path to the runway touchdown zone. Continuing an unstable approach to landing was defined as Unstable Approach Risk Misperception in this research. A review of the literature revealed that an unstable approach followed by the failure to execute a rejected landing was a common contributing factor in runway excursions.

Ab initio computation of gas radiation properties for re-entry flow simulations
PI Eric Perrell
CO-I Fanny Thomas
CO-I Spatika Iyengar
Renewed interest in planetary atmospheric entry, descent, and landing underscores the need for improved physics modeling in computational fluid dynamics. From a recent NASA solicitation, “the current state of the art for predicting aerothermal environments for planetary entry are dependent on physical models and underlying numerical methods that are, in many cases, two to five decades old.” Uncertainty in experimental data used in radiation heat transfer computations leads to, “over-engineering” of entry body heat shields, at a large weight and cost penalty. A method for computing gas emissivity and absorptivity from quantum mechanics principles is developed.

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?

What Differentiates Superior Performing Aviation and Aerospace Leaders
PI Linda Pittenger
The requirements of leaders today are radically different than just a couple years ago. Leaders need to be able to manage change, think critically, act globally, think technologically, and successfully lead a diverse workforce. Specific behavioral competencies may distinguish superior performing leaders from average performing leaders

Matrix Analysis and Operator Theory
PI Edward Poon
Matrices and operators are ubiquitous throughout science, engineering, and mathematics; they are the transformations that arise whenever one studies a linear system (or approximates a nonlinear system by a linear one). Examples include rotations and reflections (rigid motions of space), spin operators (quantum mechanics and quantum computing), stress tensors (mechanics), regression and curve fitting (statistics and data analysis), derivatives and linear differential operators (dynamical systems), to name just a few. By studying various properties, relations, and transformations of matrices and operators one may obtain insight into a wide range of phenomena.
