During this lecture, published by Columbia Gorge Community College, viewers will learn to express "... a given quantity using different systems of units." The importance of unit conversion is introduced and then three units of conversion are explained. The methods include the Internet, using a...

During this lesson, published by Columbia Gorge Community College, viewers will learn to express a given quantity using different systems of units. The lecture begins with an introduction to the concept of converting quantities to desired systems of units. A list of equivalencies for different...

This lesson, from the Technological Education Pathways Partnership (TEPP), examines the internal workings of USB drives. A PowerPoint presentation lays out the makeup of basic USB thumb drive devices, as well as some standards and applications, and a Word document guides students through a teardown...

This resource discusses using the National Instruments digital I/O high-reliability feature set for industrial applications. "This white paper describes the operation of these features, demonstrates the features in typical scenarios, and illustrates how to program the features in LabVIEW." This...

This video, provided by Columbia Gorge Community College, is the first part of a two part lecture that discusses V/Hz control for motor drives. This lecture defines base and maximum frequency, and examines "simple linear V/Hz profiles and more advanced quadratic V/Hz profiles, dual slope V/Hz...
