Algorithms for Multicriteria Scheduling Problems

Tariq S. Abdul-Razaq and Karar F. Abdul-Razaq

basrah journal of science, Volume 34, Issue 3, Pages 1-12

In this paper, we consider the multicriteria scheduling problem on single machine to minimize two criteria: maximum cost function, denoted by maximum late work (Vmax) and maximum earliness (Emax). We propose several algorithms based on types of objectives function to be optimized. The solutions of the proposed procedures are compared with that of the optimal solutions and Pareto optimal solutions for the smaller instance size, these algorithms dealing with hierarchical minimization problem as well as simultaneous minimization problem with and without weight. Computational results show the usefulness of these procedures.

On Generalization of Beta Operators

Rihab R. Abdul-Rezaq; Ali J. Mohammad; and

basrah journal of science, Volume 34, Issue 3, Pages 33-44

In this present paper, we introduce a generalization definition to Beta weight functions depend on a non-negative integer r called r-Beta. This definition restricts to the classical Lupas and to the classical Beta weight functions whenever r=0,1 respectively. In addition, we used these weight functions to define two operators of summation and of summation-integral types. Surly, these operators restrict to the classical Lupas operators and to the classical Beta operators of both summation and summation-integral types whenever r=0,1 respectively. In addition, we can get the mixed operators of Lupas-Beta and Beta-Lupas for a suitable chose of integer values. Furthermore, we derive a Voronovaskaja-type asymptotic formula for the new operators from which we can get the similar formulas for many operators of summation and summation-integral types of mixed Lupas-Beta (or Beta-Lupas) weight functions and more.

A Reliable Algorithm of Homotopy Analysis Method for Solving Fuzzy Integral Equations of Fractional Order

Salam A. Ahmed

basrah journal of science, Volume 34, Issue 3, Pages 104-119

In this paper, we based on the homotopy analysis method (HAM), a powerful algorithm is developed for the solution of linear and nonlinear fuzzy integral equations of fractional order. The proposed algorithm presents the procedure of constructing the set of base functions and gives the high-order deformation equation in a simple form. This method different from all other analytic methods, it provides us with a simple way to adjust and control the convergence region of solution series by introducing an auxiliary parameter h. The fractional derivative is described in the Caputo sense and the fractional integration is described in the Riemann-Liouville formula. The analysis is accompanied by some numerical examples to show the accuracy and validity of this approach.

J.W.P. Hirschfeld; Najm A.M. Al-seraji; and

basrah journal of science, Volume 34, Issue 3, Pages 157-169

The aim of the paper is to classify certain geometric structures, called arcs. The main computing tool is the mathematical programming language GAP. In the plane PG(2,17), the important arcs are called complete and are those that cannot be increased to a larger arc. So far, all arcs up to and including size eight have been classified, as have complete 10-arcs, 11-arcs, 12-arcs, 13-arcs and 14-arcs. In the plane of order seventeen, the maximum size is eighteen. Each of these arcs gives rise to an error-correcting code that corrects the maximum possible number of errors for its length.

basrah journal of science, Volume 34, Issue 3, Pages 170-181

An element x of an integral domain R is called primal if whenever x divides a product a1a2 with a1 , a2∈ R, x can be written as x = x1x2 such that xi divides ai ,i =1,2.We study whenin X2 primal in A + X B[X] or A + X B[[X]], when A ⊆ B be an extension of domains. Also we show that if A is an integral domain and S ⊆ A a splitting multiplicative system, then A+XAS[X] is a semirigid GCD-domain if and only if A is a semirigid GCD-domain and for each two elements of S, one of them divides the other.

Robust Hotelling's Statistic for Test A Hypothesis of Mean Multivariate Population Based on RMCD

Abdullah A. Ameen; Mohand N. Abdul - Seid

basrah journal of science, Volume 34, Issue 3, Pages 182-195

Hotelling’s statistic is an important to test a hypothesis about the mean of a multivariate normal population with location and scale parameters (with the proposition that the scale parameter is unknown positive definite matrix ) . However, hypothesis test based on this statistic can be adversely affected by outliers. In this paper, an alternative technique is proposed based on a statistic which uses the reweighted minimum covariance determinant (RMCD) estimators instead of the classical mean vector and covariance matrix . A simulation technique has been used as a technique to make a comparison between the classical and the proposed statistic by generating the data that have a contaminated multivariate normal distribution from one side and from two sides . The results have shown that, the proposed robust statistic is almost better than the classical statistic depending on the rates of type I error and the power test.

Twenty four normal toothbrushes were tested for adult persons ,12 brushes used by healthy individual and 12 brushes used by patient of oral infection( gingivitis or periodontitis) each brush was used for at least 5 weeks period .
Both brushes of two groups were colonized by large number of organisms ranged from 0.2×102 to 3.5×102 C.F.U/ml on healthy individual brushs and from 2.8×102 to 5×102 C.F.U/ml on patient brushes.
Each brushes of healthy individual yielded various types of organisms as Pseudomonas, Staphylococcus epidermidis, Staph.aureus, Gram positive rods and yeast but most brushes of patients yielded one type of organisms.
T- test analysis appeared that there were high significant difference at (P < 0.05) between brushes of two groups in the total mean of different organisms that isolated from them.
Pseudomonas recorded highest proportion (57% of total organisms isolated on all brushs of two groups; 83% of brushs) followed by Staphylococcus (36% of total isolated organisms ; 58% of brushs) Gr+ve recorded lowest proportion( 3% of total isolated organisms ; 33% of brushs) .
Staph. epidermidis , Staph. aureus could isolate from brushes of patient in 6 days after brushing while Pseudomonas isolated after 3 days.
This study demonstrated Staphylococcus and Pseudomonas as pathogen agent that cause oral infections and conclude that toothbrushes may be as a source of opportunistic pathogen such these microorganisms by wrong storing ways or by the same infected person

basrah journal of science, Volume 26, Issue 1, Pages 52-64

Wind is one of the major sources for generating water surface gravity waves.
Throughout Iraq, overall surface winds come from the northwest at 5-10 knots an
average. Three stations A,B and C were selected situated along the southern entrance
of Khor ABDULLAH which extended to the distance 20 km.Wave estimation
depends on the Sverdrup, Munk (1947) and Bretschneider (1952) method which is
possible to be applied for computing the wind-sea significant wave height on a fully
developed sea at storm area to the higher waves of greater importance in relation to
their effect on ships or coastal structures, while beyond the storm area the swell
significant wave height and swell period are computed by using Neumann and Pierson
(1966) prediction method, the combined significant wave height is computed by using
data of wind speed observed at 10 m over sea surface recorded at Abadan station in
the north of Arabian gulf. The results shows that the higher wave height is around 1.7
m in summer season in the range of years 1990-2000,also the higher swell and
combined waves are 1.3 m and 2.1 m in summer in the same range of years at the
southern entrance of Khor ABDULLAH in accordance with the field data. The
manner of increasing of the wind speed and wave height is parallel. The slope of coast
at these stations is shallow and mild. The waves breakers occurs on coast are spilling
and plunging breakers.

A.J. Harfash

basrah journal of science, Volume 25, Issue 1, Pages 17-32

A fourth order compact difference scheme with a Crank-Nicolson technique is employed to discretize three dimensions unsteady state microscale heat transport equation. By introducing an intermediate function for the heat transport equation, we use the fourth order compact scheme. The general form of the solution is solved using the Gauss-Seidel method .The stability of this new scheme is proved unconditionally stable with respect to initial values. We use the test problem to compare the accuracy of this new scheme. The results show that the compact fourth order finite difference scheme is more accurate than the second order finite difference schemes
