Evaluation Of Spectrum Of 2-Periodic Tridiagonal-Sylvester Matrix
(Scientific Technical Research Council Turkey-Tubitak, 2016)
The Sylvester matrix was first defined by JJ Sylvester. Some authors have studied the relationships between certain orthogonal polynomials and the determinant of the Sylvester matrix. Chu studied a generalization of the ...
Existence Of The Global Attractor For The Plate Equation With Nonlocal Nonlinearity In R-N
(Amer Inst Mathematical Sciences-Aims, 2016)
We consider Cauchy problem for the semilinear plate equation with nonlocal nonlinearity. Under mild conditions on the damping coefficient, we prove that the semigroup generated by this problem possesses a global attractor.
A Generalization of J - Quasipolar Rings
(Univ Miskolc Inst Math, 2017)
In this paper we introduce a class of quasipolar rings which is a generalization of J-quasipolar rings. Let R be a ring with identity. An element a is an element of R is called delta-quasipolar if there exists p(2) = p is ...
Nearly Perfect Sequences With Arbitrary Out-Of-Phase Autocorrelation
(Amer Inst Mathematical Sciences-Aims, 2016)
A sequence of period n is called a nearly perfect sequence of type gamma if all out-of-phase autocorrelation coefficients are a constant gamma. In this paper we study nearly perfect sequences (NPS) via their connection to ...
Modules Which Are Self-P-Injective Relative To Projection Invariant Submodules
(Ovidius Univ Press, 2017)
In this article, we focus on modules M such that every homomorphism from a projection invariant submodule of M to M can be lifted to M. Although such modules share some of the properties of PI-extending (i.e., every ...
More On Sequential Order Of Compact Scattered Spaces
(Scientific Technical Research Council Turkey-Tubitak, 2018)
The proper forcing axiom is shown to imply that a compact scattered sequential space with scattering height at most omega(1) must have sequential order at most omega.
Odd Burr Lindley Distribution With Properties And Applications
(Hacettepe Univ, Fac Sci, 2017)
In this study, we introduce a new model called the Odd Burr Lindley distribution which extends the Lindley distribution and has increasing, bathtub and upside down shapes for the hazard rate function. It includes the odd ...
On The Use Of Imputation Methods For Missing Data In Estimation Of Population Mean Under Two-Phase Sampling Design
(Hacettepe Univ, Fac Sci, 2018)
Non-response is an unavoidable feature in sample surveys and it needs to be carefully handled to avoid the biased estimates of population characteristics/parameters. Imputation is one of the latest fascinating methods which ...
Robust Model Selection Criteria For Robust S And Lts Estimators
(Hacettepe Univ, Fac Sci, 2016)
Outliers and multi-collinearity often have large influence in the model/variable selection process in linear regression analysis. To investigate this combined problem of multi-collinearity and outliers, we studied and ...
On The Ratio Of Maximum And Minimum Degree In Maximal Intersecting Families
(Elsevier Science Bv, 2013)
To study how balanced or unbalanced a maximal intersecting family F subset of ((vertical bar n vertical bar) (r)) is we consider the ratio R(F) = Delta(F)/delta(F) of its maximum and minimum degree. We determine the order ...
On 3-Uniform Hypergraphs Without A Cycle Of A Given Length
(Elsevier Science Bv, 2017)
We study the maximum number of hyperedges in a 3-uniform hypergraph on n vertices that does not contain a Berge cycle of a given length l. In particular we prove that the upper bound for C2k+1-free hypergraphs is of the ...
A New Proposed Model of Restricted Data Envelopment Analysis By Correlation Coefficients
(Elsevier Science Inc, 2013)
The concept of efficiency in data envelopment analysis (DEA) is defined as weighted sum of outputs/weighted sum of inputs. In order to calculate the maximum efficiency score, each decision making unit (DMU)'s inputs and ...
A New Improved Estimator of Population Mean in Partial Additive Randomized Response Models
(Hacettepe Univ, Fac Sci, 2017)
In this study, we have developed a new improved estimator for the population mean estimation of the sensitive study variable in Partial Additive Randomized Response Models (RRMs) using two non-sensitive auxiliary variables. ...
Qualitative Results on the Dynamics of A Berger Plate with Nonlinear Boundary Damping
(Pergamon-Elsevier Science Ltd, 2016)
The dynamics of a (nonlinear) Berger plate in the absence of rotational inertia are considered with inhomogeneous boundary conditions. In our analysis, we consider boundary damping in two scenarios: (i) free plate boundary ...
Quantitative Homogenization of Attractors of Non-Newtonian Filtration Equations
(Hindawi Publishing Corporation, 2010)
For a rapidly spatially oscillating nonlinearity g we compare solutions u(is an element of) of non-Newtonian filtration equation partial derivative(t)beta(u(is an element of)) - D(vertical bar Du(is an element of)vertical ...
Quasipolar Subrings of 3 X 3 Matrix Rings

An element a of a ring R is called quasipolar provided that there exists an idempotent p is an element of R such that p is an element of comm(2)(a), a + p is an element of U(R) and ap is an element of R-qnil. A ring R is ...
Quasipolarity of Special Morita Context Rings
(Univ Miskolc Inst Math, 2018)
In this paper, we introduce a new concept of Morita context rings which we call special Morita context rings. We determine the conditions under which this kind of rings are quasipolar. We use special Morita context rings ...
