This article presents a method to adjust the elements of small wind power plant speed characterized by highest annual level energy. Tests were carried out on basis distributions at three locations. The standard range speeds was reduced that resulting from in these construction generators and their excitation adapted characteristics turbines. results obtained for designed plants compared with th...

Vesicle availability partly determines the efficacy of synaptic communication in the CNS. The authors recently found that some hippocampal glutamate vesicles exhibit reluctance to exocytose during short, high-frequency action potential trains. These same vesicles can be "coaxed" into exocytosis by increased Ca(2+)entry, by direct depolarization of synaptic terminals, or by challenge with hypert...

The purpose of this paper is to introduce a different type of converter circuit used to drive switched reluctance motors. It continues with detailed discussion on the resonant converter armed at minimizing or eliminating the transistors switching losses. Finally the drive has been tested on a disc-type reluctance motor for the perfomance and functionality.

Various electric machines can be the candidate for electric vehicles applications, including induction machines, permanent magnet synchronous machines, switched reluctance machines, etc. Another class of machine, which has been relatively ignored, is synchronous reluctance machines. In order to enhance and increase torque density of pure synchronous reluctance machines, the low cost permanent m...

We evaluate an external segment-type switched reluctance motor (ESSRM) generator via simulations and experiments on actual ESSRM. In the simulation, shape of ESSRM was optimized using a genetic algorithm with two sizes varied as parameters. As result calculating 480 different shapes, it is found that model by has 1.45% higher power generation efficiency 95.08% 634W generated 2,896W than single ...

This paper presents a new methodology for modeling the inductance curves of switched-reluctance machines using cubic splines based on Lagrange form polynomials. The proposed allows estimation instantaneous and derivative in each phase machine. All steps are presented discussed, detailing information necessary its use. results an experimental computational simulation, both as motor generator, es...

Nowadays, water pumping systems based on photovoltaics as a source of electricity have widely increased. System cost and efficiency still require enhancement in order to spread their application. Perovskite solar cells (PSCs) are the most hopeful third-generation photovoltaic for replacing silicon-based thanks high power conversion efficiency, reaching 25.8%; tunable band-gap; long diffusion le...

Reluctance to try novel tastes (neophobia) can be exacerbated in arousing situations, such as when children are under social stress or in rodents, when the new taste is presented in a high arousal context (HA) compared to a low arousal context (LA). The present study aimed at determining whether adrenergic transmission at the Insula regulates the reluctance to try novel tastes induced by arousi...
