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...

The University of Michigan Virtual Reality Laboratory (VRL) at the College of Engineering explores innovative applications of immersive and non-immersive virtual environments in a variety of areas. For industrial applications, research is focused on virtual prototyping of engineering designs -...

This Android application from Purdue University provides a simulation of the work that advanced manufacturing technicians perform, including details on the work that they perform in automation and data exchange. The simulation is composed of five sections, including an introduction and four...

This presentation, created by Terry Bartelt of the Wisconsin Online Resource Center, examines how voltages and currents vary in a series RLC circuit as the applied frequency changes.

In this lesson from the MAPS GIS program at Lane State Community College students use skills gained from the Web-based GIS tutorial to explore the Willamette Watershed in Oregon. A correlation will be found between types of trees and the riparian zone along the McKenzie River. Population in the...

This interactive e-book from the Dolan DNA Learning Center shows the continuity of research on corn throughout the ages, from Native American agriculturalists to molecular biologists. Using animations, photographs, illustrations, time lapse video, and interviews the story of corn is told in five...

Learners read how nanotechnology is creating new jobs in emerging industries while making others obsolete. This colorful and animated activity also looks at the types of products being created through the use of technology and how educational institutions have responded.

This interactive presentation, created by authors James Bourassa and John Rosz, explains the calculations and physics behind work and power calculations. The authors address how these calculations play a vital role in engineering practices and methods. The format of the lesson is akin to an animated...

The WorldWide Telescope (WWT) is a visualization software environment that "enables your computer to function as a virtual telescope." The site offers narrated tours from astronomers and educators. An installation of the telescope must be performed before the website is functional. Additionally, the...
