A new device and technique have been developed by National Institute of Standards and Technology researchers for measuring "breakdown" voltage -- the voltage required to produce electrical arcs when ...

I discuss a teaching experiment that sought to characterize precalculus students' angle measure understandings. The study's findings indicate that the students initially conceived angle measures in ...

A Brownian spatial tree is defined to be a pair (T, ø), where T is the rooted real tree naturally associated with a Brownian excursion and ø is a random continuous function from T into ...

Indiana is the only other state that has amended AFCIs out of its building code, but a similar measure is currently pending in North Carolina, Jeffrey Sargent reported in the November/December NFPA ...
