Asymptotic results for an inventory model of type (s, S) with a generalized beta interference of chance
(Işık University Press, 2011-10-19)In this study, asymptotic expansion for ergodic distribution of an inventory control model of type (s, S) with generalized beta interference of chance is obtained, when S ? s ? ?. Moreover, weak convergence theorem is ... -
Distributional derivatives on a regular open surface with physical applications
(Işık University Press, 2011-05-03)The spatial derivatives of Schwartz-Sobolev distributions which display singularities of arbitrary order on an arbitrary regular open surface are investigated. The contributions of the present investigation to literature ... -
Energy preserving methods for volterra lattice equation
(Işık University Press, 2011-09-11)We investigate linear energy preserving methods for the Volterra lattice equation as non-canonical Hamiltonian system. The averaged vector field method was applied to the Volterra lattice equation in bi-Hamiltonian form ... -
Runs based on discrete order statistics
(Işık University Press, 2011-08-16)In the present paper, we study runs based on discrete order statistics. Limit results for the total number of such runs and the length of the longest run are derived. -
On existence of periodic solutions of the KDV type equation
(Işık University Press, 2011-07-27)We prove the existence of the periodic solutions of the KDV type of equation with respect to time variable with periodic external force. Using the integral substitution we reduce the original equation to the integral ... -
On various characterizations of supercomplete mappings

The v-invariant χ2 sequence spaces
(Işık University Press, 2011-08-01)In this paper we define v- invariatness of a double sequence space of ? and examine the v- invariatness of the double sequence space of χ. Furthermore, we give duals of double sequence space of χ. -
Lie-poisson integrators for a rigid satellite on a circular orbit
(Işık University Press, 2011-07-14)In the last two decades, many structure preserving numerical methods like Poisson integrators have been investigated in numerical studies. Since the structure matrices are different in many Poisson systems, no integrator ... -
Mathematical modeling of the dissolution process of silicon into germanium melt
(Işık University Press, 2011-10-16)Numerical simulations were carried out to study the thermosolutal and flow structures observed in the dissolution experiments of silicon into a germanium melt. The dissolution experiments utilized a material configuration ... -
A prediction regarding the weakening of the blue shift of light from geosynchronous satellites
(Işık University Press, 2011-06-13)We base the present approach, on an alternative theory of gravitation, consisting essentially on the law of energy conservation broadened to embody the mass & energy equivalence of the Special Theory of Relativity, and ... -
The χγ2F − summable sequences of strongly fuzzy numbers
(Işık University Press, 2011-05-20)We introduce the classes of χγ2F − summable sequences of strongly fuzzy numbers and give some relations between these classes. We also give a natural relationship between χγ2F − summable sequences of strongly fuzzy numbers ... -
On generalized sarmanov bivariate distributions
(Işık University Press, 2011-05-15)A class of bivariate distributions which generalizes the Sarmanov class is introduced. This class possesses a simple analytical form and desirable dependence properties. The admissible range for association parameter for ... -
On complex multiplicative differentiation
(Işık University Press, 2011-08-05)In the present paper we discuss multiplicative differentiation for complexvalued functions. Some drawbacks, arising with this concept in the real case, are explained satisfactorily. Some new difficulties, coming from the ... -
Generalized (2+1)−dimensional breaking soliton equation
(Işık University Press, 2011-04-05)In this work, a general (2+1)-dimensional breaking soliton equation is investigated. The Hereman’s simplified method is applied to derive multiple soliton solutions, hence to confirm the model integrability. -
Variation formulas of solution for a controlled functional-differential equation considering delay perturbation
(Işık University Press, 2011-03-05)Variation formulas of solution are proved for a controlled non-linear functionaldifferential equation with constant delay and the continuous initial condition. In this paper, the essential novelty is the effect of delay ... -

Application of the homotopy perturbation method (HPM) and variational iteration method (VIM) to gas dynamic equation
(Işık University Press, 2011-02-26)A gas-dynamic control system is one where the path of an object in flight is controlled by either the generation or redirection of gas flow out of an orifice rather than with the traditional movable control surfaces. In ...
