In this paper, we propose few numerical algorithms for minimization of unconstrained non-linear functions by using Modified homotopy perturbation method and the another new algorithm based on Modified Adomian decomposition method. Then comparative study among the seven new algorithms and Newton’s algorithm is established by means of examples.

In this paper we introduce a new class G (F) l of sequence of fuzzy numbers. It is a subclass of G(F), the space of all entire sequence of fuzzy numbers. The completeness and some topological properties of G (F) l are discussed. Also it is proved that G (F) l is a Banach space and it has monotone metric. Some matrix transformations involving this space are obtained.

The increasing requirements for the environmental protection have resulted in the search for more effective, inexpensive and ecologically safe solutions. Zeolite is one of the alternatives, which due to their peculiar structure are widely used for various environmental processes. The demand for an easily accessible and inexpensive source of zeolite has raised interest in synthesis of these min…

The purpose of this study is to review many of the available guidelines for Polymer composite materials. Guide lines for failure mode, laminates orientation, winding angle, water absorption, as they strongly influence the mechanical properties of composite materials. The present review is focused on composite laminates made of glass, carbon, graphite, hybrid and natural fiber composites, since …

Methods are described for the development of a desktop computerised aid for steam and air properties calculation using Microsoft Excel TM and associated Visual Basic for Applications (VBA) automation tool. The methods allow for overcoming the tedious routines of conducting mid-point interpolation calculations. The methods can be extended to other fluids’ properties data calculations.

The ever-rising diffusion of cellular phones has brought about an increased concern for the possible consequences of electromagnetic radiation on human health. Possible thermal effects have been investigated, via experimentation or simulation. This study focuses on the thermal effect response of a semi-infinite biological tissue due to global mobile radiation in retina eye tissue . Maxwell's eq…

For soil to be suitable for high way design and constructions, they must meet existing local requirements for index properties in addition to certain strength criteria. Samples of lateric soil from two locations along Igbatoro road in Southwestern Nigeria were differently stabilized with varying quantities of rock flour from 2% to 10%. The objective of this study was to determine the effect of…

An exact solution for the unsteady mixed convective MHD flow of an incompressible viscous electrically-conducting fluid over an infinite vertical isothermal plate impulsively held fixed in a uniform stream is presented here. A uniform magnetic field is assumed to be applied transversely to the direction of the flow, taking into account the induced magnetic field. The governing equations are so…
