Convergence indicators of water crisis management policies: A review study

Background and Aim: Achieving macro goals in countries is always a function of correct policies, which is necessary to create alignment and convergence of responsible agencies through a comprehensive and convergent policy. The water crisis is one of the issues in which the lack of consistent policies can lead to inefficiency of programs and ultimately the loss of opportunities. A prerequisite f...

Second Order Sliding Mode Control With Finite Time Convergence

In this paper, a new smooth second order sliding mode control is proposed. This algorithm is a modified form of Super Twisting algorithm. The Super Twisting guarantees the asymptotic stability, but the finite time stability of proposed method is proved with introducing a new particular Lyapunov function. The Proposed algorithm which is able to control nonlinear systems with matched structured u...

The second order spectrum and optimal convergence

The Second Order Spectrum and Optimal Convergence

The method of second order relative spectra has been shown to reliably approximate the discrete spectrum for a self-adjoint operator. We extend the method to normal operators and find optimal convergence rates for eigenvalues and eigenspaces. The convergence to eigenspaces is new, while the convergence rate for eigenvalues improves on the previous estimate by an order of magnitude.
