The Dynamic Voltage Restorer (DVR) is one of the most efficient and effective custom power devices in protecting sensitive equipment against voltage sag harmonics due to; lower cost, smaller size dynamic response. inverter core DVR it directly affects performance DVR, incorrect injection or delay process would be dangerous to loads. major functions controller are, detection disturbances events ...

AngII AT2 receptor modulates AT1 mediated descending vasa recta endothelial Ca2+ signaling. We tested whether the respective AT1 and AT2 receptor subtype antagonists, losartan and PD123319 could block the descending vasa recta (DVR) endothelial intracellular calcium ([Ca]i) suppression induced by AngII. AngII partially reversed the increase in [Ca]i generated by cyclopiazonic acid (CPA, 10 M), ...

Nicotine addiction is a major public health problem, resulting in primary glutamatergic dysfunction. We measured the glutamate receptor binding in the human brain and provided direct evidence for the abnormal glutamate system in smokers. Because antagonism of the metabotropic glutamate receptor 5 (mGluR5) reduced nicotine self-administration in rats and mice, mGluR5 is suggested to be involved ...

To restore the load voltage, Dynamic Voltage Restorer (DVR), which is installed between the supply and a sensitive load, should inject voltage and active power from DVR to the distribution system during voltage sag. Due to the limit of energy storage capacity of DC link, it is necessary the minimize energy injection from DVR. In this paper the techniques of the supply voltage sag compensation i...

Despite the progressive switch to digital TV, there has not been any significant change to the value chain of the TV industry. At the same time, the introduction of novel information and communication technologies, such as the digital video recorder (DVR) and efficient Peer-to-Peer (P2P) content distribution, have been regarded as a threat to the established broadcast business players. Previous...

ANG II constricts descending vasa recta (DVR) through Ca(2+) signaling in pericytes. We examined the role of PKC DVR pericytes isolated from the rat renal outer medulla. The PKC blocker staurosporine (10 microM) eliminated ANG II (10 nM)-induced vasoconstriction, inhibited pericyte cytoplasmic Ca(2+) concentration ([Ca(2+)](cyt)) elevation, and blocked Mn(2+) influx into the cytoplasm. Activati...

Using patch clamp, we induced depolarization of descending vasa recta (DVR) pericytes or endothelia and tested whether it was conducted to distant cells. Membrane potential was measured with the fluorescent voltage dye di-8-ANEPPS or with a second patch-clamp electrode. Depolarization of an endothelial cell induced responses in other endothelia within a millisecond and was slowed by gap junctio...

Original scientific paper This paper focuses on the advancement of electric power quality tendencies of an induction motor as well as alleviating the consequence on account of the prolonged duration voltage discrepancy and also quite a short time period voltage variance of these kinds of that over voltage, under voltage continuous interruption, impermanent voltage fall together with voltage cli...

This paper discusses design and simulation of dynamic voltage restorer for improve power quality & reduce the harmonics distortion of sensitive load. Electronics devices are very sensitive load against harmonics. DVR proposed not only to improve PQ but also to reduce HD due to the presence of non-linear load. The DVR consists of injection transformer, filter, ESS, VSI and control system. The ba...

A new method is suggested for the calculation of the microcanonical cumulative reaction probability uia flux autocorrelation relations. The Hamiltonian and the flux operators are computed in a discrete variable representation (DVR) and a well-behaved representation for the Green’s operator, G( E + ), is obtained by imposing absorbing boundary conditions (ABC). Applications to a one-dimensional-...
