Nearly one year to the date of last year’s I-35 Bridge Collapse in Minneapolis, a report released yesterday says at least one in four U.S. bridges needs repairs and at least $140 billion is needed to make them.
According to the report, 152,000 of the country’s 600,000 bridges are either structurally deficient or functionally obsolete. The report says the five main problems facing these bridges are: age, congestion, soaring construction costs, lack of funds for maintenance and the staggering costs associated with new bridges.
More than a dozen people were killed and 145 injured when the I-35 bridge collapsed Aug. 1, 2007 bridge collapse. The NTSB determined the bridge collapsed under the weight of tons of sand and construction materials that were stored at two of the structure’s weakest points. See the report here.
Bridge safety continues to be a concern across the nation. Last weekend, a 1,200-lb chunk of concrete fell onto highway traffic after the slab tore off the underside of an overpass in St. Paul, MN. An inspection on the I-35E overpasses says the 50-year-old bridge is “structurally safe.”

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.
