The Boston Globe is reporting today that an engineering firm is recommending the Massachusetts Turnpike Authority install about 900 new support anchors in the Ted Williams Tunnel. This is the same firm that was hired to inspect all Boston Big Dig tunnels following the July 2006 Boston Big Dig tunnel collapse that killed a 38-year-old woman when the car she was riding in was crushed by falling ceiling panels.
Powers Fasteners of Brewster, NY was charged last summer with a single count of involuntary manslaughter in the woman’s death. Milena Del Valle was killed in July 2006 with a portion of Boston’s Big DigInterstate-90 connector tunnel ceiling collapsed and crushed the car she was riding in with her husband. Powers Fasteners provided the epoxy used to secure the bolts to suspend the tunnel roof ceiling.
These anchors, according the Globe story, would be a backup in 250-ft sections near tunnel entrances which officials say are impossible to inspect because they were designed without a crawl space. These new supports would “fortify epoxy bolts, which were blamed for the fatal ceiling collapse.”
Gary Klein, an engineering consultant from Wiss, Janney, Elstner Assoc., the firm hired to review all the MTA’s roads, tunnels and bridges, gave this recommendation today at the Turnpike Authority’s monthly meeting. He did not estimate the cost of installation.

Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
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.
