Numerical comparison of methods for solving a special fourth-order boundary value problem
(
Elsevier Inc.
, 2007 , Article)
In this paper, we implement relatively new analytical techniques, the differential transform method, Adomian decomposition, and homotopy perturbation method, for solving a fourth-order boundary value problem. In these ...
Homotopy perturbation method for nonlinear partial differential equations of fractional order
(
Elsevier B.V.
, 2007 , Article)
The aim of this Letter is to present an efficient and reliable treatment of the homotopy perturbation method (HPM) for nonlinear partial differential equations with fractional time derivative. The fractional derivative is ...
Spectroscopic investigation of the donor-acceptor interaction between o-phenylenediamine and tetracyanoethylene in dichloromethane
(
Elsevier B. V.
, 2007 , Article)
The interaction between the electron donor o-phenylenediamine (o-phendn) and the π-acceptor tetracyanoethylene (TCNE) has been investigated spectrophotometrically in dichloromethane at 25 °C. The results indicate that the ...
Homotopy analysis method for fractional IVPs
(
Elsevier
, 2007 , Article)
In this paper, the homotopy analysis method is applied to solve linear and nonlinear fractional initial-value problems (fIVPs). The fractional derivatives are described by Caputo’s sense. Exact and/or approximate analytical ...
Influence of adhesive thickness and filler content on the mechanical performance of aluminum single-lap joints bonded with aluminum powder filled epoxy adhesive
(
Elsevier B.V.
, 2007 , Article)
The objective of this study was to develop information on the influence of adhesive thickness and aluminum filler content on the mechanical performance of aluminum joints bonded by aluminum powder filled epoxy. The adhesive ...
Self-Imaging based Dispersion Compensation: Performance and Tolerance of the System
(
IEEE
, 2007 , Article)
Transmitting ultra wideband (UWB) pulse signals over optical fiber is a certain sign of chromatic dispersion (CD) existence. CD is a serious problem in optical transmission because the velocity of light depends on the ...
Alternative method of diffraction-enhanced imaging
(
Elsevier B.V.
, 2007 , Article)
Diffraction-enhanced imaging (DEI) is a radiographic technique that derives contrast from an object's X-ray absorption, refraction gradient and small-angle scatter properties (extinction). The DEI imaging system prepares ...
Composite sandwich structures for crashworthiness applications
(2007 , Article)
Fibre-reinforced polymer sandwiches are promising materials for reducing vehicle mass, thereby improving the fuel economics. Nonetheless, to fully explore these materials as the primary structures and energy absorbers in ...
