Synthesis and spectroscopic structural investigations of the charge-transfer complexes formed in the reaction of 2,6-diaminopyridine with π-acceptors TCNE, chloranil, and DDQ
(
Elsevier
, 2007 , Article)
Molecular charge-transfer complexes of the donor 2,6-diaminopyridine (2,6-DAPY) with π-acceptors tetracyanoethylene (TCNE), 2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ) and tetrachloro-p-benzoquinone(chloranil) were studied ...
An adaptive Monte Carlo integration algorithm with general division approach
(
Elsevier
, 2007 , Article)
We propose an adaptive Monte Carlo algorithm for estimating multidimensional integrals over a hyper-rectangular region. The algorithm uses iteratively the idea of separating the domain of integration into 2ssubregions. The ...
The multistage homotopy-perturbation method: A powerful scheme for handling the Lorenz system
(
Elsevier
, 2007 , Article)
In this paper, a new reliable algorithm based on an adaptation of the standard homotopy-perturbation method (HPM) is presented. The HPM is treated as an algorithm in a sequence of intervals (i.e. time step) for finding ...
On multistage ranked set sampling for distribution and median estimation
(
Elsevier B.V.
, 2007 , Article)
A variation of ranked set sampling (RSS), multistage RSS (MSRSS), is investigated for the estimation of the distribution function and some of its quantiles, in particular the median. It is shown that this method is ...
A rich learning lesson using the Poisson distribution
(
Elsevier B.V.
, 2007 , Article)
In this note, we explore the rich information about inference that the Poisson distribution has. The source of this information is mainly the fact that the mean and variance of this distribution are equal.
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 ...
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 charge-transfer interactions between 1,4,7-trimethyl-1,4,7-triazacyclononane and the acceptors iodine, TCNE, TCNQ and chloranil
(
Elsevier
, 2007 , Article)
The interaction of the interesting polynitrogen cyclic base 1,4,7-trimethyl-1,4,7-triazacyclononane (TMTACN) with the σ-acceptor iodine and π-acceptors tetracyanoethylene (TCNE), 7,7,8,8-tetracyanoquinodimethane (TCNQ) and ...
Positron annihilation and ion beam analysis of ion-bombardment-induced hydrogen release and oxidation of ultra high molecular weight polyethylene
(
Elsevier
, 2007 , Article)
Ultra high molecular weight polyethylene was bombarded with He+ and Ar+ ions to fluences ranging from 1013 to 2×1016 ions/cm2. Rutherford backscattering and nuclear reaction analysis were applied to study mechanism of ...
On the Lp boundedness of rough parametric Marcinkiewicz functions
(
Victoria University of Technology
, 2007 , Article)
In this paper, we study the Lp boundedness of a class of parametric Marcinkiewicz integral operators with rough kernels in L(log + L)(Sn-1). Our result in this paper solves an open problem left by the authors of ([6]). © ...
