Embedded machine learning has presented the ability to increase the effectiveness of embedded systems by offering a new means to process and adapt to complex data enabling them to detect patterns, anomalies, and repetition in sensor data. Myoelectric sensing systems can take advantage of these properties by detecting patterns from an array of electrodes to categorize and adapt to a specific individual's muscle movements, enhancing control of robotic systems, or prosthetics. This article discusses a proposed implementation of such a system using edge computing neural networks on an STM32F746 MCU using a TI ADS1198 ADC SPI peripheral.

Embedded virtualization is a key enabler for system designers to meet SWaP-C requirements for mission critical systems that execute various military, aerospace, medical, and commercial applications. The demand is now on the software designer to implement high assurance software that can reliably satisfy safety and time critical requirements. This article presents the first public implementation of the formally proven microkernel, seL4, on the RISC-V hypervisor using H-extension v0.6.1. This implementation uses the Rocketchip softcore executing in the FPGA fabric of a Zynq UltraScale+MPSoC ZCU102.

This case study explores anomalous results from an administration of the 'Experiences with Information Literacy' (IL) add-on Topical Module to the National Survey of Student Engagement (NSSE) at Grand Valley State University (Allendale, Michigan) in 2016, and finds that wording of NSSE survey questions can significantly influence results in certain contexts. Overall, summary responses for participating students compared positively to the aggregate means for all participating Large Public institutions in the 2016 NSSE cohort, on both the core NSSE survey and the IL module. However, analysis of local responses to the IL module questions broken out by individual colleges within the university revealed an anomaly. Students in GVSU's college of engineering and computing appeared to report very low engagement on nearly all of the items in the IL module;further disaggregated into separate programs comprising the college, data appeared to perhaps indicate that engineering students' educational experience with respect to information literacy learning at GVSU is qualitatively different from that of their peers in other academic and professional disciplines, even within their own college, which also includes Computer Science and Occupational Safety and Health. In 2018 Senior GVSU engineering majors received a modified NSSE-IL survey (with permission obtained from NSSE), to explore whether Senior GVSU engineering majors may be graduating with lesser information literacy learning preparation than other GVSU graduates. Results suggest that revising NSSE-IL framing questions does result in some significant changes in rates of certain responses, some tending in a positive direction toward the institutional mean, others tending negatively away from it. We conclude that NSSE-IL in 2016 has in fact allowed us to observe an anomaly, that Seniors in one specific program do not share a perception of information literacy experiences in common with their peers in other programs at the same

Over the last 50 years, Machine Design textbooks have been continually updated to include instruction on current technology and to include the latest standards. However, current technology has not been incorporated in the teaching of the material. Specifically, there is a chapter in most texts that addresses basic finite element analysis (FEA) theory. However, FEA is not used to teach the concepts of machine design. Conversely, the content of machine design is not used to enhance students' FEA skills. These two topics are natural partners and can be used to enhance the learning of both topics. The pedagogy presented in this paper seeks to bridge these gaps. FEA has been applied to many aspects of machine design to better understand the interplay between machine elements. Very little of this research is currently incorporated in the teaching of machine design, even though FEA is commonly used in industry for machine element selection and design. Additionally, the tool itself is not used to explore complex interactions between machine elements in the classroom to allow students to better understand the interactions and have a better feel for implementing these elements in complex systems. Although in many schools, students learn the theory behind FEA and how to use it, they get little opportunity to apply the knowledge gained to "real life" scenarios. Using FEA to teach machine design provides an ideal opportunity to expose students to interpretation of FEA results. Five modules were developed to encourage exploration of machine elements using FEA: Modal Analysis of a Shaft, Stress and Deflection Analysis of a Shaft, Press Fit of a Component on a Shaft, Effect of Changing Pitch and Pressure Angle on Contact and Bending Stresses in a Spur Gear, and Gasketed vs. Non-gasketed Bolted Joints. Each module includes a theoretical background section, a model set-up section and a list of questions for the student to answer by exploring the results of their simulations. Addition

In the Grand Valley State University (GVSU) engineering undergraduate program, students complete an interdisciplinary two-semester senior design capstone project. The project is typically industry-sponsored, includes design and build phases, and results in a working prototype delivered to the sponsor. In recent years, enrollment in our program has dramatically increased, requiring a doubling of the number of senior projects (and project sponsors). Identifying viable projects, while maintaining expected standards in terms of challenging yet feasible designs, has become significantly more difficult as a large number of new sponsors are needed. To that end, we have been looking beyond our traditional industry partners for other sources for project sponsorship. Fortunately, recent collaboration with the Natural Resources Management (NRM) program in the Biology Department at our own university has proven to be a fruitful source of excellent interdisciplinary projects. It turns out that wildlife management is an area ripe for new technological advances with numerous applications. Many of the projects with the NRM group are based on the need to track and count populations of wildlife. In some projects, we assume that the wildlife is somehow tagged or collared while in other projects, we create the animal collar. These projects create a need to develop environmentally rugged yet technologically flexible communication links. For example, in one project, the animals (the American marten, see Figure 1) wear small collars with an RF transmitter that serves as a locating signal. Traditionally, small aircraft with antennas mounted on the plane (or hand held) fly low in tight routes, scanning the ground. Instead, our students developed an Unmanned Aerial Vehicle (UAV) drone that flies above the tree line and scans the surrounding area for a signal. This UAV employs a Software Defined Radio (SDR) system to directionally locate the animal while transmitting this information to the b
