Escape Room
No full textGather a team of friends to explore an abandoned Arctic research station, solve puzzles, race against the clock, defeat an alien parasite, and learn more about the Library’s Open Access resources along the way. But watch out! There’s something in the ice, and it won’t stay frozen forever. Plus, anticipate some eatable prizes!
Important! Sign up for the Escape Room here (form opens for responses at noon on Thursday, October 23.) All registrants after the first five groups will go on a waitlist
Open Access Blackout Poetry
No full textTake a break and create! Transform Open Access articles and materials into poems you can keep in hand-crafted notebooks from Book Arts.
Knowledge creation is a collaborative endeavor. But most academic research is locked behind paywalls, available only to those in high-resource communities and institutions. Open Access publishing offers another way, making research available to anyone with an internet connection. As part of International Open Access Week, we invite you to reimagine Open Access texts by redacting words so that a unique poem emerges. The New York Times interactive blackout poetry tool gives you a sense of the possibilities. Pop in anytime from 1pm-4pm to join the celebration
Sit Down, But Not For Too Long
No full textThis lesson introduces undergraduate students to the concept of hostile architecture through an in-depth exploration of anti-homeless bench design in urban environments. It aims to help students identify both visible and disguised design features that deter unhoused individuals from using public spaces, while encouraging critical reflection on the ethical, social, and cultural implications of these practices
Suspension and Wheel End Design for an Electric Race Car
No full textDartnouth Formula Racing placed 12th in the 2024 Formula Hybrid-Electric (FH+E) competition. An updated suspension system is required to improve the acceleration and handling for the 2025 car in order to place higher. To achieve this, the rim size will be reduced from 13’’ to 10’’, camber adjustability will be incorporated into the uprights, and a front anti-roll bar will be added. Using Susprog 3D and kinematic analysis, chassis pickup points and linkage geometry were optimized for the 10” wheels. The full vertical travel and steering behavior of the wheels was analyzed. Designs were developed for the uprights, brake rotors, control arms, rocker arms, steering arms, and push rods to fit the smaller rims. The uprights feature a bolt-on lower ball joint and steering rod assembly with removable plates, enabling efficient camber adjustment without the need to reset toe alignment. The front upright allows for negative 0 to 2.36 degrees of camber adjustment, while the rear provides negative 0 to 3.12 degrees. FEA analysis and thermal simulations under worst-case scenarios confirmed that the braking system can lock all four wheels. Under simulation of realistic conditions, all parts achieved a FOS above 2, and under worst-case conditions, all achieved a FOS above 1. All components comply with FH+E and FSAE regulations and are manufacturable in-house. The new suspension system reduces the car’s weight by 10.7 kg, is estimated to increase maximum acceleration by 0.3 m/s², and should save about 1 MJ of energy during the endurance race. These improvements are expected to enhance lap times and achieve significant energy savings in competition
Marine Power Vertical Axis Tidal Turbine
No full textAs the world transitions away from fossil fuels, marine energy presents a key opportunity for a renewable future by harnessing the natural movement of water to generate clean, stable power. Our team is developing a vertical-axis tidal turbine designed specifically for oyster farmers and hatcheries in New England. This turbine attaches to dock pilings, providing a non-invasive and energy-efficient solution to support the high energy demands of aquaculture operations. Oyster hatcheries rely on consistent energy for water filtration, temperature regulation, and algae production, yet they often lack access to reliable and renewable power sources. By integrating tidal energy into their infrastructure, our system ensures resilient, localized energy production while minimizing environmental impact. The turbine’s vertical-axis design allows it to operate efficiently in shallow, low-flow environments, making it well-suited for nearshore aquaculture sites. As part of the Marine Energy Collegiate Competition (MECC), supported by the U.S. Department of Energy (DOE), we are working closely with industry mentors, oyster farmers, and coastal stakeholders to refine our design, ensuring ease of installation, maintenance, and long-term viability. As climate change drives the need for decarbonization and energy resilience, our innovative tidal turbine offers a scalable model for integrating marine energy into aquaculture, paving the way for a more sustainable future for coastal communities
Human-Centered Engineering Design - Lesson 02 - Empathy and Needfinding
No full textPurpose and audience. This is the second lesson in a series called, “Human-Centered Engineering Design.” These lessons are intended to be integrated into introductory courses on engineering design at the undergraduate level, across any engineering discipline. They are designed to function either as a sequence or as stand alone lessons to fill an existing gap in a course.
This second lesson, Empathy and Needfinding, is meant to be a first introduction to design research theory and two design research methods: the contextual observation and the contextual interview. The lesson begins with a short presentation on the main goal of design research, needfinding: discovering and clarifying unmet and undermet needs of a particular population. The lesson then provides a short experience in observing and then a short experience in interviewing, with how-to tips accompanying both exercises.
