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
Truchard will be presented the award at the 2014 Golden Mousetrap Awards ceremony during the co-located events Pacific Design & Manufacturing, MD&M West, WestPack, PLASTEC West, Electronics West, ATX West, and AeroCon.
In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
