Approximate analytic solutions for non-linear oscillators with fractional-order restoring force by means of the optimal variational iteration method

  In this paper, a new approach, namely the optimal variational iteration method (OVIM) was proposed to investigate oscillators with fractional-power nonlinearities. It was illustrated that this approach is very effective and convenient and does not require linearization or small parameter. Unlike other classical iteration methods, only one iteration leads to highly accurate results, due to a rigorous procedure...

Experimental study of structural and optical band gap of nickel doped tin oxide nanoparticles

  Nickel-doped tin oxide nanoparticles were synthesized by a simple co-precipitation method. The structural, morphological and optical properties of these nanoparticles were investigated using X-ray diffraction, transmission electron microscopy and UV-Vis spectroscopy. The X-ray diffraction revealed that all samples are pure rutile-type tetragonal phase; and the nickel doping did not change the...

Application of geographical information system (GIS) to groundwater quality investigation: A case study of Mardan district, Pakistan

  A study was conducted to determine the groundwater quality of Mardan salinity control and reclamation project (SCARP) area and its suitability for irrigation purposes. A total of 18 villages were selected and water samples were taken from each one. Spatial data of the locations were taken by Magellan GPS Receiver. These samples were analyzed in the laboratory and then compared with the irrigation water...
