By using the tanh-coth method, we obtained some travelling wave solutions of two well-known nonlinear Sobolev type partial differential equations, namely, the Benney-Luke equation and the higher-order improved Boussinesq ...
QPNM calculation for the ground state magnetic moments of odd-mass deformed nuclei: Er157-167 isotopes

Yakut, Hakan; Ekber Gulıyev; Güner, Mehmet; Tabar, Emre; Zemine Zenginerler (ELSEVIER SCIENCE BV, 2012)

A new microscopic method has been developed in the framework of the Quasiparticle-Phonon Nuclear Model (QPNM) in order to investigate spin polarization effects on the magnetic properties such as magnetic moment. intrinsic ...
Lamarle formula in 3-dimensional Lorentz space

Ersoy, Soley; Tosun, Murat (UNIV OSIJEK, DEPT MATHEMATICS, 2011)

The Lamarle Formula is known as a relationship between the Gaussian curvature and the distribution parameter (Drall) of a ruled surface in the surface theory, [12]. In R-1(3), the non-null ruled surfaces were investigated ...
Fibonacci and Lucas Congruences and Their Applications

Keskin, Refik; Demirtürk Bitim, Bahar (SPRINGER HEIDELBERG, 2011)

In this paper we obtain some new identities containing Fibonacci and Lucas numbers. These identities allow us to give some congruences concerning Fibonacci and Lucas numbers such as L2mn+k equivalent to (-1)((m+1)n) L-k ...
Fully renormalized quasi-particle random phase approximation, spurious states and ground state correlations

Guliyev, Ali; Güner, Mehmet (IOP PUBLISHING LTD, 2004)

An approach, called fully renormalized QRPA (FR-QRPA), which takes into account the Pauli principle for the ground state correlations (GSC) and fulfills the Ikeda sum rule has recently been developed. Here a new rotational ...
On idempotency of linear combinations of idempotent matrices

Özdemir, Halim (ELSEVIER SCIENCE INC, 2004)

P-1, P-2 and P-3 being any three different nonzero mutually commutative n x n idempotent matrices, and C-1 C-2 and C-3 being nonzero scalars, the problem of characterizing some situations, where a linear combination of the ...
Structural stability and decay estimate for marine riser equations

Gür, Şevket (PERGAMON-ELSEVIER SCIENCE LTD, 2011)

We study the problem of the continuous dependence of weak and strong solutions to the initial boundary value problem for multidimensional marine riser equations on the parameters of the equation. The continuous dependence ...
On Some Generalized B-m-Difference Riesz Sequence Spaces and Uniform Opial Property

Başarır, Metin; Öztürk, Mahpeyker (SPRINGER INTERNATIONAL PUBLISHING AG, 2011)

We define the new generalized difference Riesz sequence spaces r(infinity)(q)(p, B-m), r(c)(q)(p, B-m), and r(0)(q)(p, B-m) which consist of all the sequences whose B-m-transforms are in the Riesz sequence spaces ...

The MacWilliams identity for m-spotty weight enumerators of linear codes over finite fields

Özen, Mehmet; Şiap, Vedat (PERGAMON-ELSEVIER SCIENCE LTD, 2011)

Some of the error control codes are applied to high speed memory systems using RAM chips with either 1-bit I/O data (b = 1) or 4-bit I/O data (to = 4). However, modern large-capacity memory systems use RAM chips with 8, ...
