    • Using one dimensional convolutional neural networks for classifying the vibration of process pipework 

      Mohamed, Ahmed S.; Shady, Omar T.S.M.; Renno, Jamil; Sassi, Sadok; Paurobally, Mohamed R. ( AIP Publishing , 2023 , Conference Paper)
      Pipework in process facilities such as oil and gas or petrochemical plants is subjected to various dynamic excitations. Such excitations may include flow-induced forces due to turbulence or due to change in flow momentum ...

    • Vibration of Periodic Drill-Strings with Local Sources of Resonance 

      Akl, Wael; Alsupie, Hajid; Sassi, Sadok; Baz, Amr M. ( Multidisciplinary Digital Publishing Institute (MDPI) , 2021 , Article)
      A new class of drill-strings is proposed for attenuating undesirable vibrations to ensure effective operation. The drill-string is provided with passive periodic inserts, which are integrated with sources of local resonance ...

    • Vibration wave characteristics in Conventional and Periodic Drill string models 

      Abdul Majeed, Fesmi; Sassi, Sadok ( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Conference Paper)
      Drill string models are of two major types- Conventional and Periodic. Conventional drill string models are widely used due to their simplicity in manufacturing and dynamics analysis. Drill strings are affected mainly by ...

    • Wave propagation in double helical rods 

      Jamil, Renno; Sassi, Sadok; Gowid, Samer ( Elsevier , 2020 , Article)
      The propagation of waves in helical rods has been studied extensively. However, studying the wave propagation in double helical rods have received less attention although this can be useful in multiple fields of science ...
