  • Radial Basis Function Pseudo-Spectral Solution of the Non-Darcy Model in a Porous Medium 
    Pekmen, B. (BEGELL HOUSE INC, 50 NORTH ST, DANBURY, CT 06810 USA, 2017)
    In this study, the radial basis function pseudo-spectral (RBF-PS) method is applied for solving natural convective flow in a square cavity and in a curved pipe filled with a porous medium. RBF-PS constructs differentiation ...
  • RBF-DQ Solution of Natural Convection under the Effect of a Magnetic Field in a Tilted Cavity 
    Geridönmez, Bengisen Pekmen (ISFAHAN UNIV TECHNOLOGY, MECHANICAL ENGINEEING DEPT, JAFM OFFICE, ISFAHAN, 84156-83111, IRAN, 2017)
    In this study, radial basis function based differential quadrature (RBF-DQ) method is applied to the natural convection in an inclined unit square cavity under the effect of an applied magnetic field in different angles. ...
  • Replication of period-doubling route to chaos in impulsive systems 
    Fen, Mehmet Onur; Fen, Fatma Tokmak (UNIV SZEGED, BOLYAI INSTITUTE, ARADI VERTANUK TERE 1, 6720 SZEGED, HUNGARY, 2018)
    In this study, we investigate the dynamics of impulsive systems driven by a chaotic system. It is shown that the response impulsive system replicates the sensitivity and the period-doubling cascade of the drive. Illustrative ...
  • Scattering properties of impulsive difference Dirac equations 
    Solmaz, Şeyda; Bairamov, Elgiz (SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY-TUBITAK, 2021-07)
    : In this paper, we explore the Jost solutions and the scattering matrix of the impulsive difference Dirac systems (IDDS) on the whole axis and study their analytic and asymptotic properties. Furthermore, characteristic ...
  • Scattering theory of Dirac operator with the impulsive condition on whole axis 
    Solmaz, Şeyda; Bairamov, Elgiz (WILEY, 111 RIVER ST, HOBOKEN 07030-5774, NJ USA, 2020-07)
    In this paper, we study the Jost solutions of the impulsive Dirac systems (IDS) on entire axis and examine analytic and asymptotic properties of these solutions. Furthermore, we obtain a general form of the scattering ...
  • SICNNs with Li-Yorke Chaotic Outputs on A Time Scale 
    Fen, Mehmet Onur; Fen, Fatma Tokmak (ELSEVIER SCIENCE BV, PO BOX 211, 1000 AE AMSTERDAM, NETHERLANDS, 2017)
    The existence of Li-Yorke chaos in the dynamics of shunting inhibitory cellular neural networks (SICNNs) on time scales is investigated. It is rigorously proved by taking advantage of external inputs that the outputs of ...
  • Testing adiabatic expansion of polytropic universe model with SNe Ia data 
    Dil, Elif; Dil, Emre; Öztaş, Ahmet Mecit (IOP PUBLISHING LTD, TEMPLE CIRCUS, TEMPLE WAY, BRISTOL BS1 6BE, ENGLAND, 2020-06)
    In order to obtain a better fit for the observational data, various cosmological models have been developed in the literature. For this purpose, we propose an adiabatic expansion of the Universe with a polytropic fluid ...
  • Unpredictable oscillations of SICNNs with delay 
    Fen, Mehmet Onur; Fen, Fatma Tokmak (ELSEVIERRADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS, 2021-11-13)
    We rigorously prove that unpredictable oscillations take place in the dynamics of shunting inhibitory cellular neural networks (SICNNs) with delay when rectangular input currents generated by an unpredictable sequence are ...
  • Unpredictable solutions of linear differential and discrete equations 
    Fen, Mehmet Onur; Akhmet, Marat; Tleubergenova, Madina; Zhamanshin, Akylbek (SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY-TUBITAK, ATATURK BULVARI NO 221, KAVAKLIDERE, TR-06100 ANKARA, TURKEY, 2019)
    The existence and uniqueness of unpredictable solutions in the dynamics of nonhomogeneous linear systems of differential and discrete equations are investigated. The hyperbolic cases are under discussion. The presence of ...
  • Unpredictable Solutions of Linear Impulsive Systems 
    Fen, Mehmet Onur; Akhmet, Marat; Tleubergenova, Madina; Nugayeva, Zakhira (2020-10)
    We consider a new type of oscillations of discontinuous unpredictable solutions for linear impulsive nonhomogeneous systems. The models under investigation are with unpredictable perturbations. The definition of a piecewise ...
