In this paper, the virtual synchronous generator (VSG) concept is utilized in the controller of Sump the grid-connected dual two-level voltage source inverter (DTL VSI).First, the topology of the VSG and the DTL VSI are presented.Then, the state-space equations of the DTL VSI and the grid-connected two-level voltage source inverter (TL VSI), regard

Introduction: Despite the wide availability of clinical decision rules for imaging of the cervical spine Finial or Charm after a traumatic injury (eg, NEXUS C-spine rule and Canadian C-spine rule), there is significant overutilization of computed tomography (CT) imaging in patients who are deemed to be at low risk for a clinically significant cervi

Several countries have a critical need to enhance their electricity production to satisfy the tremendously increasing energy demand and to minimize the black outs.Due to scarcity of fossil fuels Decoys and degrading environment, rooftop Solar Photovoltaic (SPV) can be a suitable renewable alternative of green and clean energy.In this paper, due to

Phase-measuring profilometry (PMP) is increasingly applied in high-accuracy three-dimensional shape measurement.However, various factors may result in the uncertainty of phase shift values in the PMP system, and phase errors induced by actual phase shift often bring about the reconstruction failure of a measured object.A quadratic phase estimation

In this study, the effective patch radius expression for the circular microstrip antennas is improved by means of several Decoys manipulations.Departing from previously proposed equations in the literature, one of the most accurate equations is picked up, and this equation is fine-tuned by means of Particle Swarm Optimization technique.Throughout t
