Silicon On Chip (SOC) consists of several logical gates connected to define some functionality. Timing Closure being a well known art to ensure that every single timing path between consecutive ...

This paper presents a constraint logic programming model for the traveling salesman problem with time windows which yields an exact branch-and-bound optimization algorithm without any restrictive ...

Scientists have built a clock which is 37 times more precise than the existing international standard. The quantum-logic clock, which detects the energy state of a single aluminum ion, keeps time to ...

Physicists at the National Institute of Standards and Technology (NIST) have built an enhanced version of an experimental atomic clock based on a single aluminum atom that would neither gain nor lose ...
