Range Safety And Design For Launch, Space Dynamics Laboratory

Space Dynamics Laboratory Publications

Design to make licensing and launch easy

• Sometimes the most innovative or elegant solution isn’t the best one
• The less you have to prove, the better
• Don’t use novel materials
• Don’t use novel methods

Example: 3D printing is cool and reduces part count because you can design otherwise unmachinable parts

• Now you have to test, analyze, and prove to everyone that your part won’t fail
• If you machined the parts from AL 6061-T6 and bolted them together with stainless steel fasteners, nobody would have looked twice

Open Educational Resources For and As Assessment

The need to rethink assessment in higher education has become increasingly urgent due to the shift to remote teaching during the COVID-19 pandemic and the recent introduction of various generative artificial intelligence (GenAI) tools. Globally, instructors are called to redesign their assessment practices to make them more innovative, authentic, and empowering.

Evaluation Of A Semiconductor Optical Amplifier For Free Space Optical Communication Applications, Charlotte K. Duda, Chadwick Lindstrom, Francisco Fonta, Ben Stuhl, Aaron Cross, Julie Smith

Space Dynamics Laboratory Publications

High-power semiconductor optical amplifiers (SOAs) are a promising alternative to erbium-doped fiber amplifiers (EDFAs), which are traditionally used for free-space optical communication (FSO). Here, we characterize the performance of a watt-class 1550 nm Aura^TM SOA for FSO applications. We demonstrate an open eye diagram for 26.8 dBm SOA output power using the Space Development Agency’s (SDA) tranche 1 protocol. We then show that despite some waveform distortions, frame error rates of 3.9 x 10^-4 are achieved for -28 dBm of received optical power with no forward error correction (FEC). Parameters of importance to optical communications such as signal …

Feasibility Of Producing Non-Structural Wood Products Using Trembling Aspen Lumber, Mengyuan Zhang

Aspen Bibliography

Trembling aspen (Populus tremuloides) is abundant in Canada but underutilized in non-structural solid wood products.This study was aimed at evaluating the feasibility of using aspen lumber to produce flooring, moulding, and siding. The shrinkage, surface roughness, and wettability of aspen wood were tested. The surface hardness, screw withdrawal resistance, colour change, and dimensional stability of there products fabricated were examined. The wood yield of each product was analyzed. It was found that aspen showed superior machinability and wettability to silver maple and yellow poplar. Aspen flooring had a Brinell hardness of 13.47 MPa, 60% lower than silver maple. …

13. Mentorship Matters: Documenting The Unseen Impact Of Instructor-Student Relationships, Jeff Spears, Amanda Deliman, Hannah Mae Lewis, Jim Lamuth, Kim Hales

Documenting Teaching Excellence

This chapter explores the critical yet often unrecognized role of documenting instructor mentorship as a core component of teaching excellence in higher education. Mentorship encompasses a range of instructor-to-student interactions, including academic guidance, psychosocial support, research support (graduate and undergraduate), and career exploration for students (DeAngelo, Mason, & Winters, 2016; Thiry & Laursen, 2011). Despite its importance, mentorship is rarely documented comprehensively in teaching documentation portfolios (Ocobock et al., 2022). By systematically capturing the multifaceted impacts of mentorship, instructors enhance their teaching portfolio and contribute to the broader discourse on teaching excellence. This chapter aims to empower instructors to demonstrate …

14. Loops, Badges, And Remixes: How Ctls Support Documenting Scholarly Teaching, Travis N. Thurston

Documenting Teaching Excellence

College instructors today face mounting pressure to document and demonstrate teaching excellence, but too often they confront ambiguous requirements disconnected from teaching values. However, what if the future of scholarly teaching depended on making instructors feel visible, validated, and valued in how their teaching is documented and shared? In the current climate, where burnout and disconnection run high, instructors need more than compliance checklists, they need structures of support that affirm their professional identity and invite them into a community of inquiry to support scholarly teaching.

15. Documenting Teaching Excellence: Applying Universal Design For Learning (Udl) In Communication Courses, Shihua Brazill

Documenting Teaching Excellence

As a professor in communications, I know firsthand the challenges and rewards of teaching diverse students in courses such as Presenting Technical Information, Public Speaking, Interpersonal Communication, and Intercultural Communication. These courses demand not only mastery of content but also the ability of students at varying levels of comfort and expertise to communicate effectively using a variety of media. My approach to teaching has been heavily influenced by the Universal Design for Learning (UDL) framework, which I have found to be an invaluable tool for creating inclusive, engaging, and dynamic learning environments. UDL has become essential to my pedagogy because …

16. Confronting "I Just Don't Have Time": An Argument For Seeking And Documenting Professional Learning, Sharon Lyman, Karin Dejonge-Kannan

Documenting Teaching Excellence

We confess our teaching is not always exemplary and our students often struggle to learn. We argue that intentionally pursuing professional learning is the only way to improve our teaching, and that documenting this learning is imperative when we make the case for teaching excellence. This chapter will examine the common lament of “I just don’t have time” for professional learning, followed by a discussion of how to exchange this self-sabotaging notion for a self-sustaining alternative, and a description of the benefits of documenting professional growth. The aim of this chapter is three-fold: to argue that “I just don’t have …

17. Our Teaching Excellence: Effective Teaching As An Inherently Collective Endeavor To Enhance Student Learning, Melissa E. Ko

Documenting Teaching Excellence

Higher education has long pursued excellence in its core pillars: research, service, and teaching. Yet, public trust in higher education is at an all-time low. In 2024, nearly 1 in 3 Americans reported little to no confidence in higher education (Nietzel, 2024). Another survey revealed that 1 in 2 Americans think a college degree is less important now for getting a well-paying job compared to 20 years ago (Pew Research Center, 2024). Individual faculty continue to secure tenure through demonstrated teaching excellence, yet higher education struggles to convince the American public of its effectiveness. Why does this discrepancy exist?

Open Educational Resources For and As Assessment

This chapter will discuss the topic of compassion and its role in the selection and application of open educational assessment practices. Drawing on research and practice that centers compassion within assessment activities and everyday life, it will focus on four emerging themes, namely: understanding compassionate assessment, self-compassion and assessment, compassion for students in assessment, and compassion for faculty in assessment practices. It will propose that embracing and integrating open assessment practices offers a meaningful path forward.

2. Leveraging Open Pedagogy To Create An Authentic And Renewable Curriculum, Erin Mckenney, Sam Winemiller, Hillary Fox, David Tully, Will Cross

Open Educational Resources For and As Assessment

The high cost of course materials is a barrier for many students, and traditional assessments often fail to inspire engagement. To address these challenges, NC State University Libraries promotes open course materials and open-enabled practices. Since 2014, the Alt-Textbook Project has helped faculty incorporate Open Educational Resources (OER) into their syllabi, reducing textbook costs and supporting innovative educational approaches. This effort was enhanced with the Open Pedagogy Incubator, a multi- semester program bringing together librarians and interdisciplinary faculty to redesign courses around open- pedagogical practices. Dr. McKenney, an incubator participant, redesigned her advanced undergraduate course on Applied Ecology (AEC 400) …
