Renewable energy sources such as wind, solar, geothermal and tides have increasingly been used to generate electricity. Among these energy sources wind power has gained enormous attention in many parts of the world where no fossil fuels exist and energy requirements are highly demanded. The efficiency of wind power mainly depends on wind produced and a generator converting wind power to electri...

Electro deposition of NiFeWS thin films was carried out from diammonium citrate bath at a constant current density (1 A/dm 2 ) and controlled pH of 8 by varying the citrate bath concentration(0.2, 0.3, 0.4, 0.5 mol / lit). Physical properties such as surface morphology, microstructure and magnetic properties such as coercivity, saturation magnetization and magnetic flux density were investigate...

Kilogauss-strength magnetic fields are often observed in intergranular lanes at the photosphere in the quiet Sun. Such fields are stronger than the equipartition field Be, corresponding to a magnetic energy density that matches the kinetic energy density of photospheric convection, and comparable with the field Bp that exerts a magnetic pressure equal to the ambient gas pressure. We present an ...

Nowadays study of input voltage quality on induction motors behavior has become a controversial subject due to the wide application of these motors in the industry. The impact of grid voltage fluctuations on the performance of induction motors can be included in this area. The majority of papers devoted to the influence of voltage fluctuations on the induction motors are focusing only on the so...
