Large-Scale Advanced Prop-Fan (LAP) blade design

This report covers the design analysis of a very thin, highly swept, propeller blade to be used in the Large-Scale Advanced Prop-Fan (LAP) test program. The report includes: design requirements and goals, a description of the blade configuration which meets requirements, a description of the analytical methods utilized/developed to demonstrate compliance with the requirements, and the results of these analyses. The methods described include: finite element modeling, predicted aerodynamic loads and their application to the blade, steady state and vibratory response analyses, blade resonant frequencies and mode shapes, bird impact analysis, and predictions of stalled and unstalled flutter phenomena. Summarized results include deflections, retention loads, stress/strength comparisons, foreign object damage resistance, resonant frequencies and critical speed margins, resonant vibratory mode shapes, calculated boundaries of stalled and unstalled flutter, and aerodynamic and acoustic performance calculations

The Impact of Long-Term Disruptions on Academic Success in Higher Education and Best Practices to Help Students Overcome Them

Disruptions in the delivery of academic content in higher education had been minimal as recently as 2020. Learning obstacles have not only become more frequent but also exhibit increased duration due to climate related natural disasters, and most recently, global health pandemics. The primary investigators explore the negative impacts these events have had on students’ academic success, and the best practices implemented by colleges and universities to help students overcome these issues, and persist in attaining personal and academic goals. Analysis will examine institutional-based efforts for academic student support, guidance, and motivation together with the students’ resiliency efforts. Analysis will also describe the effects on the online delivery of academic content. Findings demonstrate that one of the best ways institutions can encourage academic success is through self-resiliency, and that proactive steps mitigate stressful events

The Results Of A Longitudinal Study Of The Effects Of Network Delays On Learning

The use of interactive web-based teachingmaterials has become an indelible feature of the educational landscape over thelast decade especially for technical subjects such as engineering andmathematics. While web-based simulations present great opportunity to providestudents with the feedback needed for the acquisition of new concepts, it hasbeen demonstrated that even small network delays can adversely affect thepedagogical efficacy of these simulations. In the present work a longitudinalstudy is performed to examine the effects of network delay on learning asstudent’s progress from freshmen to senior year.  Findings indicate that by the time studentshave progressed to their senior year, they have taken on a more conservativelearning style and that their learning style is less sensitive to networkdelays than it was when they were freshmen. The study suggests that the accumulation of experience is an importantfactor in mitigating the effects of network delay on learning

The Difference In The Effects Of Longitudinal Effects Of Network Latency On STEM And Non-STEM Students

As enrollment in online courses increases faster than the overall enrollments in higher education, the differences in learning styles and academic disciplines need to be identified.  Further, the focus on the demand for students pursuing degrees in the sciences, technology, engineering and mathematics (STEM) has gained prominence in the past decade.  An experiment was conducted to study the interaction of objective learning and subjective learning, objective learning and enjoyment, and subjective learning and enjoyment on the longitudinal effects of network latency on students who were classified as STEM majors or non-STEM majors (humanities and social sciences).  The findings indicate that students from different majors responded differently by the time students have progressed to their senior year in reference to their learning styles and sensitivity to network delays than it was when they were freshmen.  The study suggests that the accumulation of experience and choice of major are important factors in mitigating the effects of network delay on learning
