Engineering equations apply to much more than just engineering. Registered civil engineer and former Boeing structural engineer, Patricia Kramer, took equations normally used to calculate the structural integrity and placement of cargo doors on an airliner to explain the evolutionary record of early humans. "The equations can predict how much energy is required for something to move in space," says Kramer, now a University of Washington (Seattle, WA) doctoral candidate and lecturer in anthropology. "If you take them and develop models that take into account the different leg lengths for Lucy and modern humans, and calculate the different levels of energy required for each, the result is a comparison of how much energy is required for Lucy and a modern human to move at any speed." Lucy is the name of the 40%-complete skeleton of a small female Australopithecus afarensis, discovered by Donald Johanson in Ethiopia in 1974. Kramer found that Lucy and her colleagues walked through life in no more than a stroll, matching the environmental demands of the time. Call: (206) 286-6698 or e-mail: firstname.lastname@example.org.
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
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.
