In this paper, we suggest a method to solve the multispecies Lotka-Voltera equations. The suggested method, which we call modified homotopy perturbation method, can be considered as an extension of the homotopy perturbation method (HPM) which is very efficient in solving a varety of differential and algebraic equations. The HPM is modified in order

In this paper, a new reliable modification of the homotopy perturbation method (HPM) is introduced and applied to the differential and integral equations. A comparative study between the modified homotopy method (MHPM) and the standard HPM is conducted. The efficiency of the modified technique is examined by several illustrative examples. In all ca

In this paper, the modified homotopy perturbation method is applied for analytical treatment of differential equations. The modified HPM yields an analytical solution in terms of a rapidly convergent infinite power series with easily computable terms. The efficiency of the modified technique is examined by several illustrative examples. In all case

A similitude has been obtained for a planar wedge with attached bow shock at high incidence in supersonic flow. A strip theory in which flow at a span wise location is two dimensional developed by Ghosh is been used. This combines with the similitude to lead to a piston theory which gives closed form of solutions for unsteady derivatives in pitch.

Polyurethane (PU)/nanosilica composite was fabricated and then coated on polyethylene (PE) film using a rod Mayer technique. The silica nanoparticles used have an average particle size of 16 nm, and their weight fractions varied from 0 to 14%. Two different thicknesses of PU/nanosilica coating layer were fabricated, which were 4 and 8 μm. The morp

Violence against women occurs in all countries and transcends social, economic, religious, and cultural groups. One of the most common forms of violence against women is violence by their husbands or other intimate male partners. Over the past two decades, violence by an intimate partner has been identified throughout the world as a serious physica

The polymorphisms of Waxy (Wx) microsatellite and G-T single-nucleotide polymorphism (SNP) in the Wx gene region were analyzed using simplified techniques in fifteen rice varieties. A rapid and reliable electrophoresis method, MetaPhor agarose gel electrophoresis (MAGE), was effectively employed as an alternative to polyacrylamide gel electrophores

Finding accurate solution of chaotic system by using efficient existing numerical methods is very hard for its complex dynamical behaviors. In this paper, the multistage homotopy-perturbation method MHPM is applied to the Chaotic Genesio system. The MHPM is a simple reliable modification based on an adaptation of the standard homotopy-perturbation

The aim of this study is to investigate the effects on forward bias characteristics of neutron radiation on various commercially available silicon and GaAs diodes. The diodes were irradiated using the Pneumatic Transfer System (PTS) facility in Malaysian Nuclear Agency with neutron fluences up to 1012 neutron/cm2.s for an exposure time of 1, 3 and

Neutron radiation testing was performed on silicon and GaAs diodes to investigate changes in the device parameters after neutron exposure. Californium-252 source was used to irradiate these diodes up to total dose of 1117.87mSv. The effects of nuclear radiation on the forward and reverse current-voltage (I-V) characteristics of Silicon and GaAs dio
