A novel stepped amplitude distribution (SAD) taper for microwave power transmission for space solar power satellite is proposed in this paper. The SAD taper is described by the summation of the ...

Automatic differentiation is a key feature of present deep learning frameworks. Moreover, they typically provide various ways to specify custom gradients within the computation graph, which is of ...

The Shockley-Queisser (S-Q) model assumes that the absorptance spectrum of a solar cell is a Heaviside step-function centered at the bandgap energy, i.e. zero below and unity above the bandgap. The ...

It is often confused with the Heaviside function, which unlike the unit step is not defined at t = 0. Both have a finite discontinuity at t = 0. Note that the Dirac delta is the derivative of the unit ...
