Simulation tools in the engineering classroom are a good thing, given the ubiquity of these tools in modern engineering practice. When I was in school a decade ago, there was minimal coverage of simulation techniques. In school, finite-element analysis was still considered a specialized topic for graduate students, while in industry, it was already well-established as a regular part of the design process.
While it's good to see students being introduced to simulation tools early on (especially in core courses such as circuit analysis, rather than specialized courses focused on computational methods), it's also important for students to understand the limits of a given simulation. They need to learn not to believe things just because they see them on a screen.
I hope that the use of MapleSim in this class is not intended to replace a more traditional electronics lab. It should not be an alternative to building the circuits on a breadboard. That's an inductive learning approach that has been around for a long time.
With erupting concern over police brutality, law enforcement agencies are turning to body-worn cameras to collect evidence and protect police and suspects. But how do they work? And are they even really effective?
A half century ago, cars were still built by people, not robots. Even on some of the country’s longest assembly lines, human workers installed windows, doors, hoods, engines, windshields, and batteries, with no robotic aid.
DuPont's Hytrel elastomer long used in automotive applications has been used to improve the way marine mooring lines are connected to things like fish farms, oil & gas installations, buoys, and wave energy devices. The new bellow design of the Dynamic Tethers wave protection system acts like a shock absorber, reducing peak loads as much as 70%.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
