As the hearing continues the focus is on the type of epoxy used in the ceiling panels that collapsed in the Big Dig tunnel last summer.
Following a presentation outlining the fundamentals of epoxy. The conversation has now turned to the difference between "fast set" epoxies and standard epoxy. The epoxy used in the tunnel in question was a fast set epoxy. And the question now is whether in effect the wrong "glue" was used and was this information availalbe to the designers, project managers and suppliers. It’s a question of the load values in terms of the type of epoxy used, along with the long-term characteristics of fast set epoxy and the safety value factor of this type of adhesive in this type of structure. Was the epoxy used appropriate for the loads it was expected to hold?
If you see a hitchhiker along the road in Canada this summer, it may not be human. That’s because a robot is thumbing its way across our neighbor to the north as part of a collaborative research project by several Canadian universities.
Stanford University researchers have found a way to realize what’s been called the “Holy Grail” of battery-design research -- designing a pure lithium anode for lithium-based batteries. The design has great potential to provide unprecedented efficiency and performance in lithium-based batteries that could substantially drive down the cost of electric vehicles and solve the charging problems associated with smartphones.
Robots in films during the 2000s hit the big time; no longer are they the sidekicks of nerdy character actors. Robots we see on the big screen in recent years include Nicole Kidman, Arnold Schwarzenegger, and Eddie Murphy. Top star of the era, Will Smith, takes a spin as a robot investigator in I, Robot. Robots (or androids or cyborgs) are fully mainstream in the 2000s.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
