In this paper, two cascaded voltage source grid-connected inverters (VSI) with Quadratic boost converter (QBC) has been described and simulated as more attractive for a grid to interface the PV system. The simulation is carried out by using open loop control method synchronize photovoltaic system these are controlled Sinusoidal Pulse Width Modulation (SPWM) approach SV (SVPWM) skill technique d...

The aim of this manuscript is to present a non-invasive method recover the network structure dynamical system. We propose use controlled probing input and measure response network, in spirit what done determine oscillation modes large electrical networks. For class systems, we show that approach analytically tractable confirm our findings by numerical simulations networks Kuramoto oscillators. ...

purpose: to report the clinical, histopathologic, microbiologic and confocal microscopic features of candida keratitis after deep anterior lamellar keratoplasty (dalk). patients and findings: the first patient presented with asymptomatic white to cream-colored interface deposits two months after dalk. confocal scan disclosed clusters of hyper-reflective fine granular deposits in the interface w...

This paper presents a non-parametric method for testing departures from a uniform seasonal variation in incidence of disease. The method may be used either with exact dates of incidence when they are available or with monthly totals. It is equally valid for sinusoidal and non-sinusoidal departures from uniformity. A simulation study shows it to be much more powerful than other non-parametric al...
