PAST COVERAGE Boston's Big Dig Leaking Like a Sieve The four-year-old Big Dig in Boston is up to its old tricks of behaving like a 70-year-old tunnel. The problem this time around are leaks, which are up 18 percent over last year after Massachusetts officials pledged to reduce them to a trickle. Full Story Big Dig Blame Game: Which Engineering Elements are at Fault for the Big Dig Tragedy? The science of tunnel-building has made up the bulk of what Big Dig investigators and local officials have been discussing in public as they try to piece together what happened. Full Story Update: Boston’s Big Dig Still Has Engineers Talking More than a month after Boston’s Big Dig was determined to have faulty bolt and epoxy assemblies, investigations are still uncovering problems and work is continuing to fix pieces of the project’s faulty infrastructure. An engineering who-done-it, it’s still driving hundreds of conversations across the Internet by engineers who continue to offer up their two cents as to what happened and why. Full StoryBoston’s Big Dig – One of Engineering’s Biggest Mistakes? With more headlines emerging every day, Boston’s Big Dig/Central Artery Tunnel Project is certainly becoming a topic everyone is talking about. With forums and blogs popping up all over the Internet in recent weeks, many techies are eager to speculate on what happened, why it happened and what the next steps should be. Full Story
APPALLING NEGLIGENCE IN BOSTON'S BIG DIG: PHOTOS TELL ALL
The NTSB has released an extensive set of photos that graphically depict mind-boggling negligence in Boston's Big Dig. Poor engineering, incompetence and perhaps worst, an utter lack of inspection over a known problem resulted in death, injury, runaway costs and endless inconvenience for drivers. Imagine driving over a bridge with visibly dangerous cracks in the girders – and doing nothing about them. That is the story of the Big Dig ceiling. View Photo Gallery
Lantronix Inc. has expanded its line of controllers for sensor networks with the release of a rugged controller that improves management of automation systems used in a number of industries, including manufacturing, oil and gas, and chemicals.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
