    • Dynamic modeling and analysis of biotrickling filters in continuous operation for H2S remova 

      Ahmed, Wasim; Shareefdeen, Zarook; Abdel-Jabbar, Nabil (2014-12)
      A number of important biotrickling filter (BTF) models are reviewed. For our study, a theoretical model, based on H2S removal in a differential BTF under batch mode, was selected among the models reviewed. Using a cascade ...

    • A Dynamic Optimal Battery Swapping Mechanism for Electric Vehicles using an LSTM-based Rolling Horizon Approach 

      Shalaby, Ahmed Ayman Ahmed; Shaaban, Mostafa; Mokhtar, Mohamed; Zeineldin, H. H.; El-Saadany, Ehab (IEEE, 2022-01)
      This paper proposes a new approach for optimal operation of an Electric Vehicle (EV) battery-swapping station (BSS) based on Rolling-Horizon optimization (RHO). The BSS has several swapping bays such that each can accommodate ...

    • Dynamic Power Characteristics of Selective Buried Oxide (SELBOX) MOSFET 

      Mahmoud, Rana (2017-02)
      The ever-increasing number of devices and electronic systems resulted in increasing the die size to satisfy the increasing demand. Moreover, the shrinking size of transistors according to the scaling theory became a ...

    • Dynamic properties of language anxiety 

      Gregersen, Tammy (Adam Mickiewicz University, 2020)
      This article begins by examining previous empirical studies to demonstrate that language anxiety, or the negative emotional reaction learners experience when using a second language (MacIntyre & Gardner, 1999), is a dynamic ...
