The National Institutes of Standards and Technology (NIST) tested facial recognition algorithms applied to nearly 27 million images to analyze their ability to identify people. NIST researchers tested artificial intelligence algorithms of 26.6 million reasonably well-controlled, live portrait photos of 12.3 million individuals. Three smaller datasets containing more unconstrained photos...

Weighing a full spool so you can calculate the weight per foot for each wire gauge. We keep one on each truck. The cost savings from being able to efficiently use partial spools will pay for the scales quickly. Even more significant is eliminating the time and frustration that results from having a conductor that is...
