  • Classical Wavelet Transforms over Finite Fields 

    Ghaani Farashahi, A. (Central Tehran Branch, Islamic Azad University, 2015-12-01)
    This article introduces a systematic study for computational aspects of classical wavelet transforms over finite fields using tools from computational harmonic analysis and also theoretical linear algebra. We present a ...

  • Duals and approximate duals of g-frames in Hilbert spaces 

    Mirzaee Azandaryani, M.؛ Khosravi, A. (Central Tehran Branch, Islamic Azad University, 2015-12-01)
    In this paper we get some results and applications for duals and approximate duals of g-frames in Hilbert spaces. In particular, we consider the stability of duals and approximate duals under bounded operators and we study ...

  • Generalized superconnectedness 

    Bouassida, E.؛ Ghanmi, B.؛ Messaoud, R.؛ Missaoui, A. (Central Tehran Branch, Islamic Azad University, 2015-12-01)
    A. Csaszar introduced and extensively studied the notion of generalized open sets. Following Csazar, we introduce a new notion superconnected. The main purpose of this paper is to study generalized superconnected spaces. ...

  • A new Approximation to the solution of the linear matrix equation AXB = C 

    Sadeghi, A. (Central Tehran Branch, Islamic Azad University, 2015-12-01)
    It is well-known that the matrix equations play a significant role in several applications in science and engineering. There are various approaches either direct methods or iterative methods to evaluate the solution of ...

  • A numerical solution of mixed Volterra Fredholm integral equations of Urysohn type on non-rectangular regions using meshless methods 

    Nili Ahmadabadi, M.؛ Laeli Dastjerdi, H. (Central Tehran Branch, Islamic Azad University, 2015-12-01)
    In this paper, we propose a new numerical method for solution of Urysohn two dimensional mixed Volterra-Fredholm integral equations of the second kind on a non-rectangular domain. The method approximates the solution by ...
