Every single day, humans rely on hundreds of hidden clocks. GPS location, Internet stability, stock trading, power grid management ... all rely on atomic clocks in order to work. Many of those clocks ...
To address the discontinuity and constant bias inherent in traditional hard and soft threshold functions, an atomicclock signal denoising method based on the hyperbolic tangent smooth threshold ...
Most clocks, from wristwatches to the systems that run GPS and the internet, work by tracking regular, repeating motions. To build a clock, you need something that ticks in a perfectly repeatable way.
