Tsĝ-space in Topological Spaces

M. M. El-Sharkasy · Journal of Advances in Mathematics and Computer Science · 2016

The aim of this paper is to introduce and study the class of sĝ-closed sets, which is properly placed between the classes of semi-closed sets due to Crossley and Hildebrand in 1974 and gs-closed sets due to Arya and Nour in 1990. Also, we investigated the relations of anew notion...

On Designing Invertible Pseudo Covariance Matrix for Undersampled Cases in Classification

Rashid Mahmood, Khalid Mahmood Aamir, Marija Milojević Jevrić, Stojan Radenović & Tehseen Zia · Journal of Advances in Mathematics and Computer Science · 2016

In linear discriminant analysis, determinant and inverse of the covariance matrix are required to be computed. If number of features is greater than the number of available examples, covariance matrix is no longer invertible. A common approach is to reduce dimensionality due to w...

A Wireless Sensor Network for Examination Attendance Management System

I. F. Obayemi, O. T. Arulogun & A. S. Falohun · Journal of Advances in Mathematics and Computer Science · 2016

Every academic institute has special concerns for student’s attendance in examination halls. At present, in developing countries attendance is usually taken using paper sheets and the old file system. The effectiveness of this style is low because it is highly labor-intensive, er...

Fast Calculation of Linear Finite Element Method for the Stationary Fractional Advection Dispersion Equations

Zhiqiang Zhou & Hongying Wu · Journal of Advances in Mathematics and Computer Science · 2016

Appropriate variational formulation and detailed implementation of linear finite element for the stationary fractional advection dispersion equation(FADE) are discussed. Since fractional derivative is nonlocal operator, the stiffness matrix of finite element on traditional variat...

Archimedean Operations-based Interval-valued Hesitant Fuzzy Ordered Weighted Operators and Their Application to Multi-criteria Decision Making

Zhiming Zhang · Journal of Advances in Mathematics and Computer Science · 2016

In this paper, the Archimedean t-conorm- and t-norm-based interval-valued hesitant fuzzy ordered weighted averaging (A-IVHFOWA) operator and the Archimedean t-conorm- and t-norm-based interval-valued hesitant fuzzy ordered weighted geometric (A-IVHFOWG) operator are given by taki...

On Jordan (θ,∅)*-biderivations in Rings with Involution

Shakir Ali, Husain Alhazmi & Abdul Nadim Khan · Journal of Advances in Mathematics and Computer Science · 2016

Let R be a ring with involution. In the present paper, we characterize biadditive mappings which satisfies some functional identities related to symmetric Jordan (θ,∅)*-biderivation of prime rings with involution. In particular, we prove that on a 2-torsion free prime ring with i...

Cofinitely G-supplemented Modules

Berna Koşar · Journal of Advances in Mathematics and Computer Science · 2016

In this work, cofinitely g-supplemented modules are defined and investigated some properties of these modules. It is shown that an arbitrary sum of cofinitely g-supplemented modules is cofinitely g-supplemented. In addition, amply cofinitely g-supplemented modules are also define...

Numerical Solution of Fourth Order Linear Differential Equations by Adomian Decomposition Method

E. U. Agom, F. O. Ogunfiditimi & A. Tahir · Journal of Advances in Mathematics and Computer Science · 2016

In this paper, we state the general Adomian Decomposition Method (ADM) for Fourth order linear differential equations. And applied it to obtain analytic solution in a rapidly convergent series to this class of equations. The concept of ADM was further applied to physical problems...

A Model of Elasticity Taking into Account the Displacement Orientation in the Deformation

Ayoub Azzayani, Soumaya Boujena & Jérôme Pousin · Journal of Advances in Mathematics and Computer Science · 2016

Aims/Objectives: In this work, we deal an elasticity model in 2D and 3D dimension for deformation under constraint by taking into account the deformation displacement orientation. This mathematical model can be used, for example, to describe the heart deformation taking into acco...

Suppression of Vibrations of a Forced and Self-excited Nonlinear Beam by Using Positive Position Feedback Controller PPF

H. M. Abdelhafez & M. E. Nassar · Journal of Advances in Mathematics and Computer Science · 2016

This paper presents a quantitative analysis on the nonlinear behavior of a forced and self-excited beam coupled with a positive position feedback controller PPF. Such that the external excitation is a harmonic motion on the support of the cantilever beam. Self-excitation is cause...
