Adaptive Modified Rise-Based Quadrotor Trajectory Tracking With Actuator Uncertainty Compensation, Emmanuel Ogbanje Ijoga, William Mackunis, Krishna Bhavithavya Kidambi, Madhur Tiwari

Publications

This paper presents an adaptive robust nonlinear control method, which achieves reliable trajectory tracking control for a quadrotor unmanned aerial vehicle in the presence of gyroscopic effects, rotor dynamics, and external disturbances. Through novel mathematical manipulation in the error system development, the quadrotor dynamics are expressed in a control-oriented form, which explicitly incorporates the uncertainty in the gyroscopic term and control actuation term. An adaptive robust nonlinear control law is then designed to stabilize both the position and attitude loops of the quadrotor system. A rigorous Lyapunov-based analysis is utilized to prove asymptotic trajectory tracking, where the region of convergence …

A Literature Review Examining Broadening Participation In Upper Elementary Cs Education, Umar Shehzad, Mimi Recker, Jody Clarke-Midura

Publications

Despite proliferated efforts to integrate computer science in elementary education, there is a dearth of studies that synthesize the current state of CS education research in formal educational contexts, specifically in upper elementary classrooms. Further, while numerous studies have investigated approaches and strategies that broaden participation in computing, the majority of them focus on secondary and post-secondary settings. The present study uses a systematic literature review process to review research conducted with students in formal classroom settings in grades 4, 5, and 6 and published since 2013. We review the research through two questions: What are barriers to broadening participation …

In this study, students took a second attempt 46% of the time, scoring an average of 10.1% higher on their second attempt. More than 60% of students who failed their first attempt completed a second attempt. Students perceived the feedback as useful in preparing for their second attempt. Future research …

Clumpy Wind Studies And The Nondetection Of A Cyclotron Line In Oao 1657–415, Pragati Pradhan, Carlo Ferrigno, Biswajit Paul, Enrico Bozzo, Ileyk El Mellah, David P. Huenemoerder, James F. Steiner, Victoria Grinberg, Felix Furst, Chandreyee Maitra, Patrizia Romano, Peter Kretschmar, Jamie Kennea, Deepto Chakrabarty

Publications

Winds of massive stars are suspected to be inhomogeneous (or clumpy), which biases the measures of their mass-loss rates. In high-mass X-ray binaries (HMXBs), the compact object can be used as an orbiting X-ray point source to probe the wind and constrain its clumpiness. We perform a spectrotiming analysis of the HMXB OAO 1657–415 with nonsimultaneous NuSTAR and NICER observations. We compute the hardness ratio from the energy-resolved light curves, and, using an adaptive rebinning technique, we thus select appropriate time segments to search for rapid spectral variations on timescales of a few hundred to thousands of seconds. The column …

The Need For Recategorized Video Game Labels: A Quantitative Approach, Richard J. Simonson, Joseph R. Keebler, Shawn Doherty

Publications

Prior research has suggested that video game genre labels are an ineffective method of communicating a game's experience. Our investigation serves to provide a quantitative means of assessing experience communication effectiveness. We assessed game similarities by their associated game genre labels. The ratio between the small number of available developer-generated labels and the number of games led to too few labels to effectively delineate between similar and dissimilar games. The ratio between the large number of user-generated labels and the number of games led to too many labels to effectively cluster similar games with one another. However, games that had …

Gravity Wave Drag Parameterizations For Earth’S Atmosphere, Christopher J. Heale, Christopher G. Kruse, Jadwiga H. Richter, M. Joan Alexander, Julio T. Bacmeister, Junhong Wei

Publications

Atmospheric gravity waves (GWs), or buoyancy waves, transport momentum and energy through Earth’s atmosphere. GWs are important at nearly all levels of the atmosphere, though, the momentum they transport is particularly important in general circulation of the middle and upper atmosphere. Primary sources of atmospheric GWs are flow over mountains, moist convection, and imbalances in jet/frontal systems. Secondary GWs can also be generated as a result of dissipation of a primary GWs. Gravity waves typically have horizontal wavelengths of 10’s to 100’s of kilometers, though, they can have scales of 1’s to 1000’s of kilometers as well. Current effective resolutions …

A Flexible Pressure Sensor With Highly Customizable Sensitivity And Linearity Via Positive Design Of Microhierarchical Structures With A Hyperelastic Model, Zhenjin Xu, Dezhi Wu, Zhiwen Chen, Zhongbao Wang, Cong Cao, Xiangyu Shao, Gang Zhou, Shaohua Zhang, Lingyun Wang, Daoheng Sun

Publications

The tactile pressure sensor is of great significance in flexible electronics, but sensitivity customization over the required working range with high linearity still remains a critical challenge. Despite numerous efforts to achieve high sensitivity and a wide working range, most sensitive microstructures tend to be obtained only by inverting naturally existing templates without rational design based on fundamental contact principles or models for piezoresistive pressure sensors. Here, a positive design strategy with a hyperelastic model and a Hertzian contact model for comparison was proposed to develop a flexible pressure sensor with highly customizable linear sensitivity and linearity, in which the …

Introduction To The Special Issue On Immunology, Colby Tofel-Grehl, Brooke A. Whitworth

Publications

The COVID-19 pandemic laid bare the absence of needed resources for teachers to engage students in learning about infectious disease as both a socioscientific issue and a scientific phenomenon (Kafai et al. 2022). With infectious disease largely absent from the NGSS, teachers had to creatively link lessons that contextualized and examined key aspects of infectious disease education during the COVID-19 pandemic. We saw in real time the impacts of popular news, social media, and public mood on broader socioscientific behaviors such as vaccination, masking, and social distancing. We watched as people’s understanding of the nature of science (Lederman 2013) …
