Eight weeks later, her notebook stays shut. When quadratic equations appear, her pencil hovers, then drops as her eyes drift to the classroom clock. The instructor asks, “What value of x balances the ...

The author presents the formulation and solution method of an optimal power flow problem using a sequential quadratic programming technique for an AC-DC power system with one or more multiterminal DC ...

In this letter we present some new sufficient conditions for the annular stochastic finite-time stability of a class of stochastic linear time-varying systems. These new conditions are obtained ...
