EXISTENCE OF SOLUTIONS FOR n-GENERALIZED MIXED VECTOR EQUILIBRIUM PROBLEMS IN BANACH SPACES |
by Zi-yan Li, Zhong-quan He & Da-peng Gao |
Abstract |
In this paper,
some generalized mixed vector equilibrium problems in Banach
spaces are
introduced and the
equivalence of two classes of h-generalized mixed vector
equilibrium problems
is proved under suitable assumptions. By using the equivalence
theorem, some results on
the existence of solutions for
h-generalized mixed
vector equilibrium
problems are obtained.

LINEAR 3-ARMENDARIZ RINGS |
by Ayoub Elshokry & Eltiyeb Ali
|
Abstract |
In
the present note we study the properties of linear 3-Armendariz rings, which are
generalization of 3-Armendariz rings and linear Armendariz rings and the connections
among linear 3-Armendariz rings, 3-Armendariz rings and ring satisfies condition (P).
We prove that a right Ore ring R
is linear 3-Armendariz if and
only if so is
Q, where Q
is the classical right quotient ring of
With the help of this result
we can show that a commutative ring
R is linear 3-Armendariz if
and only if the total quotient ring of R
is linear 3-Armendariz.

LINEAR MODELS OF DIFFERENT SCALES |
by Xian He, Xudong Zhu, Hao Zhang & Qianlai Zhuang |
Abstract |
In tMany statistical models for environmental
studies can be run at different scales, e.g., for daily, weekly or monthly data.
It is important to know how these models differ in terms of prediction. We provide
some
theoretical results to compare these models. We show that when there is no
high order terms of explanatory variables, the small scale model yields more efficient
estimators for model parameters and also produces
better prediction. However, when
there are high order terms of explanatory variables, a larger scale model can be
run in two different ways: product-of-sum or sum-of-product. Current practice made
it hard to compare directly the larger scale model with the small scale model and
no explicit conclusions are drawn in general. We provide a case study on gross primary
production of terrestrial ecosystems in the conterminous United States to demonstrate
our results.

APPROXIMATING COMMON ELEMENTS OF THE SET OF AMENABLE SEMIGROUP AND VARIATIONAL INEQUALITY AND INFINITE FAMILY OF NON-EXPANSIVE MAPPINGS AND GENERALIZED MIXED EQUILIBRIUM PROBLEMS |
by Qiang Li & Jun Li |
Abstract |
In this
paper, we introduce a new iterative scheme for finding a common element of the set
of fixed point of an infinite family of non-expansive mappings and left amenable
semigroup, the set of solution of generalized mixed equilibrium problem and the
set of solutions of the variational inequalities for solving inverse strongly monotone
mappings in Hilbert spaces by using a hybrid steepest descent methods. Then strong
convergence of the scheme to a common element of the three sets is proved. Our results
improve and generalize some well-known results in the literature.

THE ACCUMULATION OF SOME TOXIC METALS IN FOOD PLANTS NEAR A POLLUTED SITE |
by Kebir Tahar, Bouhadjera Keltoum & Baba Ahmed Abderrazzak |
Abstract |
The transfer of
heavy metals from the former sites of mining activity to the nearby agricultural
soils is a serious environmental risk and concern due to the potential health impacts
of consuming contaminated produce. The present study is determinate to the level
of nine heavy metals: Fe, Pb, Zn, Ni, Cu, Cd,
Mn, Cr and As in the different agricultural soils and three
plants alimentary: Pepper (Capsicum annuum), Artichoke (Cynara cardunculus
variety scolymus) and Grape
(Vitis vinifera) grown near of dumpsite
of site industrial activity AlZINC in Ghazaouet city western of
Algeria
country. Soil sample were takes from land in different direction, since the metal
are generally associated with the fine fraction, the investigation was carries under
2 mm
fraction sample according to NF ISO 11464 and the plants are ashes. The extraction
of all metals was using by digestion with aqua regia method (nitric-chloric acid
ratio1:3) and analysis via AES-ICP. The plant samples from the immediate
environment were highly contaminated with Zn, Cd and Mn. particularly,
grape met some of the conditions to be classifies as accumulators for Pb,
Zn, Cu, Cd, Ni and Cr consequently and she revealed
a health risk for human and livestock due to the spread of the metal pollution from
dumpsites to agricultural areas.

NEW ALGORITHM FOR SOLVING THE MODIFIED KORTEWEG-DE VRIES (mKdV) EQUATION |
by K.R. Raslan & H.A. Baghdady |
Abstract |
In this paper we will investigate the finite element approach
using collocation method with septic spline interpolation functions to solve the
Modified Korteweg-de Vries (MKdV) equation. It is unconditionally stable by von
Neumann method. The exact soliton solution and the conserved quantities are used
to assess the accuracy and to show the robustness of the scheme. The interaction of two solitary waves for different parameters is discussed.

LONG RUN IMPACT OF GOVERNMENT EXPENDITURE AND TAX ON LIQUIDITY AND EMPLOYMENT IN IRAN ECONOMY |
by Ayoub Faramarzi, Mohammad Sadegh Avazalipour, Farnaz Khaleghi & Nader Hakimipour |
Abstract |
This paper studies the impact of fiscal policy on money supply in Iran’s economy
.The trend of the main variables in this paper during the covered period are presented
and analyzed. In order to study the main factors of on employment of labor and,
Vector Auto regressive model (VAR) and Vector Error Connection (VECM) as well as
co-integration test of Johansen Co-integration Test during 1976-2009 is used to
find out the relation and also to evaluate the model.
Results
showed that the effect of government expenditure on the both of the employment
and liquidity is positive but the effect of tax on the employment is negative. The
coefficients of the tax and government expenditure on liquidity are 0.44 and 0.07.
The coefficients of the tax and government expenditure on employment are -0.17 and
0.15.

MAXIMUM LIKELIHOOD FOR GENERALIZED LINEAR MODEL AND GENERALIZED ESTIMATING EQUATIONS |
by A. Lanani |
Abstract |
The most frequent methods to analyze statistical data are the regression methods,
whereby the maximum likelihood method or that of least squares. On the one hand,
in the context of the longitudinal data or repeated measurements, these data are
often unbalanced; on the other hand, their law of probability are not normal rending
the passage to other models with other methods of estimate possible. In this paper,
we initially recalled the maximum likelihood method applied to a mixed linear model;
thereafter, we introduced the generalized estimating equations and their method
of resolution. Finally, we showed the relationship between the maximum likelihood
method and the iteratively reweighted least squares ones.

APPLICATION OF THE BPOMS FOR NUMERICAL SOLUTION OF THE ISOTHERMAL GAS SPHERES EQUATIONS |
by Behrooz Basirat & Mohammad Amin Shahdadi |
Abstract |
In this article we present a matrix method for solving isothermal gas spheres equations (IGSEs)
with initial conditions by Bernstein polynomials operational matrices (BPOMs) on
interval [a,b]. This method transforms (IGSEs) and the given conditions into matrix
equation which corresponds to a system of linear algebraic equations.
