  • Fluid flows of mixed regimes in porous media 
    Çelik, Emine; Luan Hoang; Akif Ibragimov; Thinh Kieu (AMER INST PHYSICS, 2017)
    In porous media, there are three known regimes of fluid flows, namely, pre-Darcy, Darcy, and post-Darcy. Because of their different natures, these are usually treated separately in the literature. To study complex flows ...
  • Codes over Galois rings with respect to the Rosenbloom-Tsfasman metric 
    Özen, Mehmet (PERGAMON-ELSEVIER SCIENCE LTD, 2007)
    We investigate the structure of codes over Galois rings with respect to the Rosenbloom-Tsfasman (shortly RT) metric. We define a standard form generator matrix and show how we can determine the minimum distance of a code ...
  • A Note on Evolution of Curves in the Minkowski Spaces

    Güzeltepe, Murat; Alev Altinel (UNIV OSIJEK, DEPT MATHEMATICS, 2017)
    Let pi be a Hurwitz prime and p - pi pi*. In this paper, we construct perfect 1-error-correcting codes in H-pi(n) , for every prime number p > 3, where H denotes the set of Hurwitz integers.

    In the present work, the aim is to determine seasonal changes in the concentrations of Cd, Cr, Cu, Fe, Pb, Mn, Ni and Zn in the water of Sapanca Lake and to determine the water quality. Sapanca is one of lakes which can ...
  • Maximum estimates for generalized Forchheimer flows in heterogeneous porous media 
    Çelik, Emine; Luan Hoang (ACADEMIC PRESS INC ELSEVIER SCIENCE, 2017)
    This article continues the study in [4] of generalized Forchheimer flows in heterogeneous porous media. Such flows are used to account for deviations from Darcy's law. In heterogeneous media, the derived non-linear partial ...
  • Long-time behaviour of the solutions to inverse problems for parabolic equations 
    Gözükızıl, Ömer Faruk; Yaman, Metin (ELSEVIER SCIENCE INC, 2007)
    We study long-time behaviour as t -> infinity of the solutions of the inverse problem for parabolic equation with an unknown source function. The overdetermination condition is given in integral form. Under some conditions, ...
  • Siacci's Theorem According to Darboux Frame 
    Tosun, Murat; Akyiğit, Mahmut (OVIDIUS UNIV PRESS, 2017)
    The resolution of the acceleration vector of rigid body moving along a space curve is well known thanks to Siacci [1]. In this resolution,the acceleration vector is stated as the sum of two special oblique components in ...
