• Discontinuous coupling and transition from synchronization to an intermittent transient chimera state 

      Wang, Zhen; Hussain, Iqtadar; Pham, Viet Thanh; Kapitaniak, Tomasz ( Sharif University of Technology , 2021 , Article)
      Coexistence of coherent and incoherent clusters, called chimera state, has been observed in different coupling configurations. A majority of studies have considered a static scheme for the network. In this paper, synchronization ...
    • Measuring skewness: We do not assume much 

      Khan, A.A.; Cheema, S.A.; Hussain, Z.; Abdel-Salam, G.A. ( Sharif University of Technology , 2021 , Article)
      Since skewness plays a vital role in different engineering phenomena, its accurate measurement gains significance. Several measures have been taken to quantify the extent of skewness in distributions over the years, but ...
    • Power system frequency estimation based on simulated annealing: A variable frequency model 

      Soliman, S.A.; Alammari, R.A.; Mantaway, A.H.; El-Hawary, M.E. ( Sharif University of Technology , 2004 , Article)
      This paper presents a new technique for measuring power system frequency, rate of change of frequency and the voltage amplitude and phase angle using the Simulated Annealing (SA) based optimization algorithm. The algorithm ...
