• A Category Approach to Relation Preserving Functions in Rough Set Theory 

      Diker, Murat (Elsevier Science Inc, 2015)
      The category Rel whose objects are all pairs (U, r), where r is a relation on a universe U, and whose morphisms are relation-preserving mappings is a canonical example in category theory. One of the convenient categories ...
    • A Machine-Learning-Driven Sky Model 

      Satilmis, Pinar; Bashford-Rogers, Thomas; Chalmers, Alan; Debattista, Kurt (Ieee, 2017)
    • An Analytic Shooting-Like Approach For The Solution of Nonlinear Boundary Value Problems 

      Türkyılmazoglu, M. (Pergamon-Elsevier Science Ltd, 2011)
      In this paper a novel approach is presented for an analytic approximate solution of nonlinear differential equations with boundary conditions. By converting the nonlinear problem into an initial value form, a shooting-like ...
    • Categories of Rough Sets and Textures 

      Diker, Murat (Elsevier Science Bv, 2013)
      It is known that the theories of rough sets and fuzzy sets have successful applications in computing. Textures, as a theoretical model, provide a new perspective for both rough sets and fuzzy sets. Indeed, recent papers ...
    • Definability And Textures 

      Diker, Murat (Elsevier Science Inc, 2012)
      This paper aims to give a new perspective for definability in rough set theory. First, a counterpart of definability is introduced in textural approximation spaces. Then a complete field of sets for texture spaces is defined ...
    • Di-Uniformities and Hutton Uniformities 

      Özçağ, Selma; Brown, Lawrence M.; Krsteska, Biljana (Elsevier Science Bv, 2012)
      The authors characterize di-uniformities on a texture (S, J) in the sense of Ozgag and Brown (Di-uniform texture spaces, Appl. Gen. Top. 4(1) (2003), 157-192) in terms of functions on the texturing J. This characterization ...
    • Ditopological Texture Spacesand Intuitionistic Sets 

      Brown, LM; Diker, M (Elsevier Science Bv, 1998)
      In this paper it is shown that the lattice of intuitionistic subsets of a set X in the sense of D. Coker may be represented as a special type of texture space, called an intuitionistic texture on X, and various characterizations ...
    • Further Results On Fibre Products Of Kummer Covers And Curves With Many Points Over Finite Fields 

      Ozbudak, Ferruh; Temur, Burcu Gulmez; Yayla, Oguz (Amer Inst Mathematical Sciences-Aims, 2016)
      We study fibre products of an arbitrary number of Kummer covers of the projective line over F-q under suitable weak assumptions. If q - 1 = r(n) for some prime r, then we completely determine the number of rational points ...
    • Nearly Perfect Sequences With Arbitrary Out-Of-Phase Autocorrelation 

      Yayla, Oguz (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 ...
    • Some Issues On Hpm And Ham Methods: A Convergence Scheme 

      Turkyilmazoglu, M. (Pergamon-Elsevier Science Ltd, 2011)
      The homotopy method for the solution of nonlinear equations is revisited in the present study. An analytic method is proposed for determining the valid region of convergence of control parameter of the homotopy series, as ...
    • Spatial Behavior Estimates For The Wave Equation Under Nonlinear Boundary Conditions 

      Celebi, AO; Kalantarov, VK (Pergamon-Elsevier Science Ltd, 2001)
      Our aim is to establish a spatial decay and growth estimates for solutions of the initial-boundary value problem for the linear wave equation with the damping term under nonlinear boundary conditions. (C) 2001 Elsevier ...
