You’ve heard all about how 3D technology can be tapped to design everything from football-field-size airplanes to the latest high-tech mountain bikes. Well, what about employing 3D to solve one of the world’s great mysteries: How the Great Pyramid of Kheops was built.
Jean-Pierre Houdin, a French architect, has come up with a theory, which is says is scientifically proven thanks to the use of Dassault Systemes’ real-time 3D solutions. At a recent conference, Houdin created a virtual reality auditorium using seven networked computers running Dassault’s Virtools to recreate the pyramid construction site in 3D, exactly as it was 4,500 years ago.
Houdin’s theory is based on three foundations: The use of an outside ramp to build the first 43 metres of the pyramid; the use of an internal spiral ramp running behind the faces of the pyramid to complete construction; and the use of the Great Gallery to accommodate a system of counterweights to lift some of the heavy granite ceiling rafters, which can weigh in at up to 63 tons.
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.
