This interactive presentation, created by Terry Bartelt and hosted by the Electromechanical Digital Library, discusses the tri-state buffer used in devices employing digital circuitry. A tri-state buffer is "one type of device that is used in digital circuits receiving two logic states but producing...

Try Engineering is a portal about engineering and engineering careers. This site is intended to help young people understand what engineering actually means and how an engineering career can be made part of their future. The site features links to engineering programs at major universities and...

This 5-page article discusses the The Women in Computer Engineering (TWiCE) project. This project has proved effective in the retention of women in an undergraduate computer science engineering program. Members of TWiCE apply their developing knowledge to community service and serve as role models...

This resource provides an animation and diagrams of a Stirling Engine that illustrates expansion, transfer, and contraction. The Stirling engine is a very simple engine, and was often billed as a safe alternative to steam, since there's no risk of a boiler explosion. Stirling engines feature a...

This webpage from Edmonds Community College provides a brief introduction to a number of core materials including ceramics, composites, concrete, electronic/optical, metals, polymers/plastics and wood.

This 29-page report, published by the University of Stavanger, describes the design and construction of the underwater remotely operated vehicle (ROV) created by the UiS Subsea team for the Explorer Class of the 2023 MATE ROV competition. MATE ROV is a global competition that challenges STEM...
