To solve the time-variant Sylvester equation, in 2013, Li et al. proposed the zeroing neural network with sign-bi-power function (ZNN-SBPF) model via constructing a nonlinear activation function. In ...

Earlier research had found that the rings of Saturn respond to vibrations within the planet. Saturn's interior vibrates at frequencies that cause slight variations in its gravitational field, and the ...

Numerical techniques based on a time-domain recursive solution of the electric field integral equation (EFIE) may exhibit instability phenomena induced by the joint space-time discretization. The ...
