The present study aimed to elucidate the reciprocal interactions between oxygen (O(2)), nitric oxide (NO), and superoxide (O(2)(-)) and their effects on vascular and tubular function in the outer medulla. We expanded our region-based model of transport in the rat outer medulla (Edwards A, Layton AT. Am J Physiol Renal Physiol 301: F979-F996, 2011) to incorporate the effects of NO on descending ...

For grid-connected DFIG-based wind turbine, Fault Ride Through (FRT) or Low Voltage (LVRT) capability is vital problem that need to be improved. This paper proposes an Active Disturbance Rejection Control (ADRC) strategy applied Doubly Fed Induction Generator (DFIG) based Wind turbine (WT), which integrates a Dynamic Restorer (DVR). The DVR connect in series the DFIG output terminal and utility...

A dynamic voltage restorer (DVR) is developed to stabilize the three-phase load under sudden grid distortion conditions, including sag, swell and unbalance. The DVR composed of a DC\AC inverter DC-link capacitor regarded as energy storage element. When occurs, instant power compensate or absorb realized by resulted in degenerate stabilization performance poor transient quality load. Hence, cont...

A new approach to multi-dimensional quantum scattering by the infinite order discrete variable representation is presented. Determining the expansion coefficients of the wave function at the asymptotic regions by the solution of the differential Schrödinger equation, we reduce an infinite set of linear equations to a finite one. Application to the benchmark collinear H + H2 → H2 + H reaction is...

The discrete variable representation (DVR) basis is nearly optimal for numerically representing wave functions in nuclear physics: Suitable problems enjoy exponential convergence, yet the Hamiltonian remains sparse. We show that one can often use smaller basis sets than with the traditional harmonic oscillator basis, and still benefit from the simple analytic properties of the DVR bases which r...

For improving power quality as a cost effective solution for the protection of sensitive loads from voltage disturbances a dynamic voltage restorer (DVR) has great significance. Dynamic voltage restorers are mostly utilized to deal with voltage sag and swells in distribution systems. In this paper, a Dynamic voltage restorer and review of proposed control strategies applied in Dynamic voltage r...
