Standards Resources for Engineering and Technology

This webliography is a selective compilation of the following: major standards bodies that create or approve standards frequently used by engineers and technologists, standards database aggregators, web sites that provide free or low cost, full-text access to standards, and standards education resources. Only major standards bodies that operate in the U.S. or on an international level are incorporated, excluding non-U.S. national and regional bodies that create or coordinate standards activities in other countries. The standards education resources listed are appropriate for university-level students. All of the resources included are English language web sites. Additionally, all of the resources included are free to search; however, most standards bodies and standards aggregators charge fees for full-text access to standards documents. The Free (or Low Cost) Full-Text Access to Standards section highlights resources that provide full access to standards documents for free, or at significantly reduced costs for educators

Photogrammetry and Texture Baking: Creating Lightweight 3D Objects for Any VR Headset. In E. Kroski (Ed.) 32 Virtual, Augmented, and Mixed Reality Programs for Libraries

Patrons will learn how to make 3D objects that are viewable across a range of consumer to high-end VR headsets through the processes of photogrammetry and texture baking. Photogrammetry is an affordable and relatively simple process that recreates objects in 3D with great detail. The process includes taking photos of an object with a Smartphone and then bringing them into open-source software that aligns them into what is called a point cloud. A point cloud is the first processing step in creating a 3D object. Point clouds can be complex and data intensive, so many consumer VR headsets do not have the capacity to render the objects for optimal viewing. Texture baking makes 3D objects ‘lightweight’ in geometry for rendering, but the details are maintained using images for material properties. Lightweight 3D objects can be viewed across a range of VR headsets with stunning results. This activity includes three sections: (1) Photo Capture, 2) Photogrammetry Image Stitching, and (3) Texture Baking. Patrons will create 3D objects they can use for their video games, websites, artist portfolios and more

Integrating Foundational Data Management Course into STEM

This presentation was delivered at the IOLUG conference-Tackling Data in Libraries: Opportunities and Challenges in Serving User Communities in Indianapolis, IN in May 2019. Data literacy is critical for today’s college graduates. Data science education is fundamentally an interdisciplinary endeavor. Since summer 2018, the presenters, information professionals from the libraries, have been working with instructors from Philosophy and Computer and Electrical Engineering to develop three interlocking one-credit courses at the Midwest, public research university, Purdue University. Spring 2019, the courses are offered to engineering sophomore and junior students to explore three key areas of data literacy: management; ethics; and analysis. In this session, participants learned how we developed the libraries’ one-credit course on data management and we discussed how this course could be interlocked with two other courses. Welcome to contact and work with the presenters for class implementation and research collaboration

Ecoimmunity in Darwin's finches: invasive parasites trigger acquired immunity in the medium ground finch (Geospiza fortis)

Journal ArticleInvasive parasites pose a serious threat to native animal populations, because hosts with no history of exposure may lack effective immune defenses. Invasive parasites are a particular threat to small, island populations [1,2]. For example, introduced malaria (Plasmodium relictum) has exacerbated the decline of Hawaiian honeycreeper species, many of which are now extinct [3,4]. Darwin's finches have recently been exposed to two introduced parasites of high conservation priority: avian pox virus (Poxvirus avium) and the nest fly Philornis downsi (Figure 1A, 1B) [1,2]

Part VIII Craft Projects: Carving Cute Critters (pp. 235-239). In E. Kroski (Ed.) 53 Ready-to-Use Kawaii Craft Projects

AT THE PURDUE Library of Engineering & Science, we have a variety of services, such as 3D printing, and Maker tools for check out, such as handheld 3D scanners. We use our Maker events as a way to let students know what we have available to them. To reach as many patrons as possible, on a campus of 40,000 students, we make our events mobile and call the program Mobile Making. The events revolve around the library tools and services, including the one for this project, subtractive technologies. We host projects that support the intersection of engineering, technology, and art. The Carving Cute Critters project demonstrates subtractive, CNC technology and gives students an opportunity to paint and talk to their Library faculty and staff in an informal, fun way. With Carving Cute Critters, students are given pre-carved blocks of wood to decorate with painter markers. We use the Inventables Carvey machine and their free software, Easel, but any CNC carving machine with compatible software works for this project. This is a layered activity. Participants can either decorate wood blocks and see how a tabletop CNC carving machine works, or they can take is a step further and create their own Cute Critter to be carved. We have found this to be one of our most successful events. Students are focused on painting the blocks and ask questions about the machine. We are thanked for offering the event and asked when we will hold it again

Determinants of exclusive consumption of fluoride-free water: a cross-sectional household study in rural Ethiopia

Aim: The occurrence of high fluoride concentrations in the ground- and surface water all over the world leads to the risk of developing dental and skeletal fluorosis. In Ethiopia, 8 million people depend on water sources with excessive fluoride. In four project areas in the Ethiopian Rift Valley, fluoride removal household filters based on bone char media have been implemented. This study examines possible predictors of consuming filtered water derived from various behavior change theories. Subject and methods: In a complete cross-sectional survey, 160 filter users were interviewed through structured face-to-face interviews. A logistic regression was carried out to reveal factors predicting consumption of filtered water. Results: The results show that the consumption of fluoride-free water is mainly related to people's pride in offering filtered water to guests (status norm) and the feeling of being able to produce enough water with the filter (perceived behavioral control). Moreover, the study showed that the more filter users like the taste of filtered water and the more expensive they perceive the filter media, the more likely users will exclusively consume filtered water (attitudinal beliefs). Furthermore, perceiving the act of filling as a matter of habit (perceived habit) enhances filtered water consumption. Conclusion: Based on the results, possible intervention strategies to change the influential psychological factors and, hence, increase the consumption of treated water can be designe

Collecting Virtual and Augmented Reality in the Twenty-First Century Library

In this paper, we discuss possible pedagogical applications for virtual and augmented reality (VR and AR), within a humanities/social sciences curriculum, articulating a critical need for academic libraries to collect and curate 3D objects. We contend that building infrastructure is critical to keep pace with innovative pedagogies and scholarship. We offer theoretical avenues for libraries to build a repository 3D object files to be used in VR and AR tools and sketch some anticipated challenges. To build an infrastructure to support VR/AR collections, we have collaborated with College of Liberal Arts to pilot a program in which Libraries and CLA faculty work together to bring VR/AR into liberal arts curricula
