"Measuring Pump Efficiency: Uncertainty Considerations"—a free research symposium webcast to be given at 11 a.m. CST on May 6—will analyze the reasonable confidence intervals for pump efficiency measurements. Authored by Noah Manring, University of Missouri-Columbia, the research will also present a method for calculating this confidence interval. To register, go to www.nfpa.com/default.asp?pid=389.
Two different shape-shifting polymers have been announced from two different universities: Wyss Institute at Harvard University and Zhejiang University in eastern China. Both of them change their shapes when immersed in water, and the one from Wyss Institute was made with 3D-printing techniques.
When you think of the DARPA Robotics Challenge, you may imagine complex humanoid contraptions made of metal and wires that move like a Terminator Series T-90. But what actually happened at the much-vaunted event was something just a bit different.
