From the GeoExchange Initiative at Gateway Technical College, this Course Outcome Summary describes Direct Expansion (DX) Applications in which students learn "the unique installation and performance characteristics of Direct Expansion heat pump equipment." In addition to the course information and...

This site from the National Engineers Week Foundation features a collection of materials and activities on engineering. Topics like environmental sustainability, computer engineering, and renewable energy are included on the site. Interactive activities help students learn how engineering impacts...

This 25-page report, from Grove Academy, describes the design and construction of the underwater remotely operated vehicle (ROV) created by the Discovery Robotics team for the Ranger Class of the 2022 MATE ROV competition. MATE ROV is a global competition that challenges STEM students to build...

This website includes a Java applet that displays the effect that various operations on an N-periodic, discrete-time signal (e.g. time shift, time scale, filtering) have on the signal and its spectra. Sketch the signal or magnitude and phase spectra with the mouse, and then select the operation.

This article is a revised version of a talk the author gave 4 October during the 1998 National Academy of Engineering (NAE) Annual Meeting discussing diversity issues in engineering, in terms of both underrepresented populations and 'individual diversity.'

This tutorial is provided by National Instruments and covers how to correctly use and understand a digital multimeter (DMM). This tutorial includes a table of contents and the following sections: Display Digits, Voltage Measurements, Current Measurements, Additional Measurements, Noise Rejection...

This resource, provided by Maricopa Advanced Technology Education Center (MATEC), is a cut-away animation of a pneumatic double action gripper. The objective of the animation is to describe how the double action gripper works. A short description is included. An .mp4 is also available and runs 01:15...

This video, from Columbia Gorge Community College, is the first of a two-part series on doubly fed induction generators (DFIG). In the video, instructor Jim Pytel introduces the concept of DFIGs and contrasts them with traditional synchronous and induction generators.  During the video, Pytel...

This video, published by Columbia Gorge Community College, is the first part of a two part lecture on doubly fed induction motors. The lecture examines the construction, operation, and different operational modes of doubly fed induction motors. Also discussed is how varying rotor excitation...
