    • A Comprehensive Study of HBase Storage Architecture—A Systematic Literature Review 

      Hassan, Muhammad Umair; Yaqoob, Irfan; Zulfiqar, Sidra; Hameed, Ibrahim A. (Peer reviewed; Journal article, 2021)
      According to research, generally, 2.5 quintillion bytes of data are produced every day. About 90% of the world’s data has been produced in the last two years alone. The amount of data is increasing immensely. There is a ...

    • Fluid-solid boundary handling using pairwise interaction model for non-newtonian fluid 

      Wang, Xiaokun; Ban, Xiaojuan; He, Runzi; Wu, Di; Liu, Xing; Xu, Yuting (Journal article; Peer reviewed, 2018)
      In order to simulate fluid-solid boundary interaction for non-Newtonian Smoothed Particle Hydrodynamics (SPH) fluids, we present a steady and realistic fluid-solid boundary handling method using symmetrical interaction ...

    • Interval Observers for Discrete-Time Linear Systems with Uncertainties 

      Sergiyenko, Oleg; Zhirabok, Alexey; Ibraheem, Ibraheem Kasim; Zuev, Alexander; Filaretov, Vladimir; Azar, Ahmad Taher; Hameed, Ibrahim A. (Peer reviewed; Journal article, 2022)
      In this paper, we consider the problem involved when designing the interval observer for the system described by a linear discrete-time model under external disturbances and measurement noises. To solve this problem, we ...

    • Virtual Sensors for Nonlinear Discrete-Time Dynamic Systems 

      Sergiyenko, Oleg; Zhirabok, Alexey; Hameed, Ibrahim A.; Azar, Ahmad Taher; Zuev, Alexander; Filaretov, Vladimir; Tyrsa, Vera; Ibraheem, Ibraheem Kasim (Peer reviewed; Journal article, 2023)
      The problem of virtual sensor design for nonlinear systems under the disturbance is investigated. Two different mathematical techniques are used to solve the problem: the algebra of functions and the logic-dynamic approach. ...
