Mary Lee reports on a Stanford professor's work mapping the human brain’s signal flow. Kylie Jenner sued by second housekeeper who says she slipped a letter to Jenner pleading for help Trump says Iran ...

Abstract: Small-signal modeling of converters interfacing with ac power systems is difficult as they involve time-periodic quantities in the steady-state and their linearized dynamics result in a ...

Computational methods in fluid flow, heat and mass transfer employ numerical algorithms to approximate the governing conservation equations—mass, momentum, energy and species—over discrete ...

Each transfer function should specify the effect of that kind of node on the flow value. Recall that transfer functions should be monotonic in order to ensure convergence (using gen and kill sets ...

Abstract: A method to obtain transfer functions of active filters with a single operational amplifier is obtained. The method relies on signal-flow graphs and the theory of Mason which simplifies ...

This Python tool allows you to draw signal-flow graphs, calculate transfer functions (SymPy code is generated for further use in Jupyter notebooks), do graph manipulations (e.g., node elimination and ...
