Excitatory postsynaptic currents (EPSCs), miniature excitatory postsynaptic currents (MEPSCs), and acetylcholine-induced current fluctuations (noise) have been studied in voltage-clamped bullfrog parasympathetic ganglion cells of the atrial septum. EPSCs were also recorded from voltage-clamped sympathetic B cells and, in general, it was found that the basic properties of the EPSCs are similar i...

Even with the fluctuations in the network voltage, the AC voltage level at the customer terminals must maintain stable. The stabilization process offers a compensation holding the output voltage to protect the main equipments. This paper presents the merits of Discrete Stabilization as compared to phase and two-level voltage regulations. This paper proposes using of more complex block to the mu...

We report measurements and analysis of the voltage noise due the to vortex motion, performed in superconducting Niobium micro-bridges. Noise in such small systems exhibits important changes from the behavior commonly reported in macroscopic samples. In the low biasing current regime, the voltage fluctuations are shown to deviate substantially from the Gaussian behavior which is systematically o...

With the increasing power demand, voltage fluctuations are to be controlled for a reliable and stable power system. On the same way voltage fluctuations create reactive power mismatch in the system. To overcome these conditions we have to perform reactive power optimisation that would balance the reactive power flow of the system. There are several methods and algorithms that serve best for thi...

We theoretically investigate the phase and voltage correlation dynamics, which includes both deterministic contribution stochastic fluctuations, under a current noise generated by resistor including thermal quantum fluctuations in resistively capacitively shunted Josephson junction. An external is found to shift intensify contributions voltage. In addition effects of current, we observe relaxat...

Quantum fluctuations in a current biased Josephson junction, described in terms of the RCSJ-model, are considered. The fluctuations of the voltage and phase across the junction are assumed to be initiated by equilibrium current fluctuations in the shunting resistor. This corresponds to low enough temperatures, when fluctuations of the normal current in the junction itself can be neglected. We u...

Electric arc furnace (EAF) is one of the largest loads in electric power systems. It is highly time varying and nonlinear. Its reactive power variations cause voltage fluctuations in nearby system which is known as flicker. On the other hand the nonlinear voltage-current characteristic causes strong voltage and current harmonics in EAF. To this end Flexible AC Transmission Systems (FACTS) techn...
