Abstract
: 

Smarandache presented neutrosophic theory as a tool for handling undetermined information, and together with Wang et al. introduced single valued neutrosophic sets that is a special neutrosophic set and can be used expediently to deal with realworld problems, especially in decision support. In this paper, we propose linear programming problems based on neutrosophic environment. Neutrosophic sets characterized by three independent parameters, namely truthmembership degree (T), indeterminacymembership degree (I) and falsitymembership degree (F), which is more capable to handle imprecise parameters. We also transform the neutrosophic linear programming problem into a crisp programming model by using neutrosophic set parameters. To measure the efficiency of our proposed model we solved several numerical examples. 






Assessing the Lifetime Performance Index of Extreme Value Model Based on Progressive Type II Censored Samples


Rashad Mohamed ELSagheer,


Abstract
: 

In practice, effective management and assessment of quality performance for products is important in modern enterprises and the process capability analysis is utilized to measure business performance. Hence, lifetime performance index C_{L} is used to measure the potential and performance of a process, where L is the lower specification limit. In the technology of data transformation, this study constructs a maximum likelihood estimator (MLE) of C_{L} under the Extreme value distribution (EVD) with the progressive typeII censored sample. The MLE of C_{L} is then utilized to develop the new hypothesis testing procedure in the condition of known L. Also we assuming the conjugate prior distribution and squared error loss function, this study constructs a Bayes estimator of C_{L}. The Bayes estimator of C_{L} is then utilized to develop a credible interval in the condition of known L. Moreover, we also propose a Bayesian test to assess the lifetime performance of products. Finally, we give example and the Monte Carlo simulation to assess the behavior of the lifetime performance index C_{L}.

Tareq Mohammed Saleh Alshami,


Abstract

In this paper, we introduce new separation axioms called strong supra regularly ordered, strong supra normality ordered and strong supra T_iordered (i=0,1,2,3,4) on supra topological ordered spaces and investigate the main properties of them. The relationships among these new separation axioms are studied and illustrated with the help of examples. Also, we point out the equivalent between $T_1$ordered and strong T_1ordered spaces which introduced in [9]. 






Notes on Galgebra and its derivations


Deena AlKadi,
Rodyna A. Hosny,


Abstract
: 

In this paper we generate a Galgebra from a nonempty set; we obtain
the quotient Galgebra via normal subalgebra. Furthermore, we prove a fun
damental theorem of an epimorphism for Galgebra. We prove that every
Galgebra satisfying the associative law is a group. We also show that every
BPalgebra is a Galgebra and introduce a necessary condition for the con
verse to be true. Finally, we introduce the notion of leftright (resp. rightleft)
derivation of Galgebra. We show that the composition of two derivations is
a derivation and we investigate some related properties. 






Regional controllability for hyperbolic systems with output constraints


Ali Boutoulout,


Abstract
: 

The aim of this paper is to characterize the minimum energy control that steers a hyperbolic system to a final state between two prescribed functions only on a subregion $\omega$ of the evolution system domain $\Omega$. We give some definitions and properties of this new concept, and then we
concentrate on the determination of the control which would realize a given final state with output constraints in $\omega$ with minimum energy. This problem is solved using the Lagrangian approach and leads to an algorithm for the computation of the optimal control. The obtained results are illustrated by numerical simulations which lead to some conjectures.

Mathematical analysis of virus dynamics model with multitarget cells in vivo


Ahmed Bakr,


Abstract
: 

This paper investigates the qualitative behavior of viral infection model with multiple delays in vivo. The infection rate is given by CrowleyMartin functional response. By assuming that the virus
attack $n$ classes of uninfected target cells, we study a viral infection model of dimension $2n+1$ with discrete delay. To describe the latent period for the contacted target cells with viruses to begin producing viruses, two types of discrete delay are incorporated into the model. The basic reproduction number $R_{0}$
of the model is defined which determines the dynamical behaviors of the model. Utilizing Lyapunov functionals and LaSalles invariance principle, we have proven that if $R_{0}\le{1}$ then the uninfected steady state is globally asymptotically stable, and if $R_{0}>1$
then the infected steady state is globally asymptotically stable.

Higher order schemes for Solving Optimal Control Problems


Mostafs. A. ElKhateb,


Abstract
: 

We shall present a numerical procedure for solving optimal control problems with the extendedone step method. A control system is considered, and a cost functional is minimized. A class of optimal control problems governed by ordinary differential equations is presented. The control variables are approximated by a polynomial function and the state variables are obtained by solving a system of ordinary differential equations using extended onestep methods of order five and six. These methods are A and Lstable methods. The problem is reduced to either a constrained or unconstrained optimization problem according to the nature of the dynamic system and the given conditions, which can be solved using Hybrid penalty partial quadratic interpolation technique.

Bernoulli Matrix Approach for Solving Two Dimensional Linear Hyperbolic Partial Differential Equations with Constant Coefficients


EMRAN TOHIDI,


Abstract
: 

The purpose of this study is to give a Bernoulli polynomial approximation for the solution of hyperbolic partial differential equations with three variables and constant coefficients. For this purpose, a Bernoulli matrix approach is introduced. This method is based on taking the truncated Bernoulli expansions of the functions in the partial differential equations. After replacing the approximations of functions in the basic equation, we deal with a linear algebraic equation. Hence, the result matrix equation can be solved and the unknown Bernoulli coefficients can be found approximately. The efficiency of the proposed approach is demonstrated with one example. 






Unsteady Simulation of RotorStator Interaction in Axial Flow Pump Based on Computational Fluid Dynamics


Zhang Hua,
Shi Weidong,
Li Tongtong,
Yao Jie,


Abstract
: 

Investigations of the RotorStator Interaction in a axialflow pump at different conditions are presented in the paper. The numerical simulation of the unsteady flow field is performed with FLUENT codes based on RNG kε model and SIMPLEC arithmetic. Numerical results show that the strongcoupling evolutions of static pressure and axial velocity distribution between rotor and stator in multiconditions are periodic with the rotation of rotor. The interaction of stationary and rotating pressure field leads to periodic flow field distortions and induces pressure fluctuation. It is found that the maximum pressure amplitude of blade passing frequency occurs in the rotor inlet zone, but it deceases very fast backward to the stator. The dominant frequency at monitoring points located at rotor inlet, outlet and stator outlet, corresponds to the blade passage frequency. The axial velocity distortion resulting from the modulation of the interacting stationary and rotating flow field is affected by the blade numbers and thickness of both rotor and stator. The axial velocity shows different distributions at different conditions, and the phase of it changes cyclically.

Gan Xusheng et al,


Abstract
: 

To improve the ability of detecting anomaly intrusions, a combined algorithm is proposed based on Partial Least Square (PLS) feature extraction and Core Vector Machine (CVM) algorithms. Principal elements are firstly extracted from the data set using the feature extraction of PLS algorithm to construct the feature set, and then the anomaly intrusion detection model for the feature set is established by virtue of the speediness superiority of CVM algorithm in processing largescale sample data. Finally, anomaly intrusion actions are checked and judged using this model. Experiments based on KDD99 data set verify the feasibility and validity of the combined algorithm.

We have presented a theoretical analysis of an electromagnetic scattering problem by a perfectly conducting strip surrounded by a homogeneous biisotropic medium. This study is focused on the exact and concise formulation for the acquisition of a closed form solution in complex domain. The complete solution of electromagnetic plane wave is presented by a series one whose eigenfunctions are the generalized Gamma functions occurring in the finite diffraction theory. The scattered field is discussed in physical domain by obtaining the convergence history of the problem in transformed domain. This analysis provides the higher order accuracy solution in closed form in physical domain.

Exact solution for fractionalized Maxwell fluid using Fox Hfunction


Muhammad Jamil,


Abstract
: 

The unsteady flow of a viscoelastic fractionalized (this word is suitable when fractional derivative is used in constitutive or governing equations) Maxwell fluid model, between two infinite coaxial circular cylinders, is studied by means of the Laplace and finite Hankel transforms. The motion is produced by the inner cylinder that at the initial moment is subject to a torsional time dependent shear stress. The solutions that have been obtained, presented under series form in terms of Fox Hfunctions, satisfy all imposed initial and boundary conditions. Moreover, the corresponding solutions for ordinary Maxwell and Newtonian fluids appear as special cases of the present results. Finally, the influence of the pertinent parameters on the fluid motion, as well as a comparison between models, is shown by graphical illustrations.
