    • Adaptive human pilot model for uncertain systems 

      Tohidi, Shahab; Yıldız, Yıldıray (IEEE, 2019-06)
      Inspired by humans' ability to adapt to changing environments, this paper proposes an adaptive human model that mimics the crossover model despite input bandwidth deviations and plant uncertainties. The proposed human pilot ...
    • Chaotic behavior of gas bubble in non-Newtonian fluid: A numerical study 

      Behnia, S.; Mobadersani F.; Yahyavi, M.; Rezavand, A. (2013)
      In the present paper, the nonlinear behavior of bubble growth under the excitation of an acoustic pressure pulse in non-Newtonian fluid domain has been investigated. Due to the importance of the bubble in the medical ...
    • Comment on "modeling the electrical conduction in DNA nanowires: Charge transfer and lattice fluctuation theories" 

      Panahi M.; Chitsazanmoghaddam M. (American Physical Society, 2016)
      In a recent paper [S. Behnia and S. Fathizadeh, Phys. Rev. E 91, 022719 (2015)10.1103/PhysRevE.91.022719] an analytical approach is proposed for the investigation of the conductivity properties of DNA. The authors use mean ...
    • Control and stabilization of a rotating flexible structure 

      Morgül, Ö. (Elsevier, 1994)
      We consider a flexible beam clamped to a rigid base at one end and free at the other end. We assume that the rigid base rotates with a constant angular velocity and that the motion of the flexible beam takes place on a ...
    • Differential entropy analysis of the IDEA block cipher 

      Biryukov, A.; Nakahara, Jr. J.; Yıldırım H. M. (Elsevier, 2014)
      This paper describes a new cryptanalytic technique that combines differential cryptanalysis with Shannon entropy. We call it differential entropy (DE). The objective is to exploit the non-uniform distribution of output ...
    • Dynamic boundary control of the timoshenko beam 

      Morgül, Ö. (Pergamon Press, 1992)
      We consider a clamped-free Timoshenko beam. To stabilize the beam vibrations, we propose a dynamic boundary control law applied at the free end of the beam. We prove that with the proposed control law, the beam vibrations ...
    • A dynamic control law for the wave equation 

      Morgül, Ö. (Elsevier, 1994)
      We consider a system described by the one-dimensional linear wave equation in a bounded domain with appropriate boundary conditions. To stabilize the system, we propose a dynamic boundary controller applied at the free end ...
    • Effect of magnetic field on the radial pulsations of a gas bubble in a non-Newtonian fluid 

      Behnia, S.; Mobadersani F.; Yahyavi, M.; Rezavand, A.; Hoesinpour, N.; Ezzat, A. (Elsevier Ltd, 2015)
      Dynamics of acoustically driven bubbles' radial oscillations in viscoelastic fluids are known as complex and uncontrollable phenomenon indicative of highly active nonlinear as well as chaotic behavior. In the present paper, ...
    • A model-based scheme for anticontrol of some chaotic systems 

      Morgül, Ö. (World Scientific Publishing, 2003)
      We consider a model-based approach for the anticontrol of some continuous time systems. We assume the existence of a chaotic model in an appropriate form. By using a suitable input, we match the dynamics of the controlled ...
    • Nonlinear PDE control of two-link flexible arm with nonuniform cross section 

      Dog̃an, M.; Morgül, Ömer (IEEE, 2006-06)
      A two-link flexible arm with nonuniform or variable cross-section by design will be considered based on an exact PDE model with boundary conditions. In this research, the nonlinear controller is used to achieve set-point ...
    • Stability analysis of switched systems using Lyapunov-Krasovskii functionals 

      Çalişkan, S.Y.; Özbay, Hitay; Niculescu, S.-I. (Elsevier, 2011)
      Piecewise Lyapunov-Razumikhin functions are previously used for obtaining a lower bound for the dwell time of the switched time delay systems under the assumption that each candidate system is delay dependently stable. In ...
