  • Regional-scale co-seismic landslide assessment using limit equilibrium analysis 
    Abou-Jaoude, Grace; Wartman, Joseph; Saade, Angela; SOE; 200702670; Civil Engineering; grace.aboujaoude@lau.edu.lb
    Traditionally, regional assessment of seismic slope stability has been done using the infinite slope-rigid sliding block analysis. A major disadvantage of this approach is the resulting overestimation of the critical ...
  • Trip-based optimization methodology for a rule-based energy management strategy using a global optimization routine 
    Mansour, Charbel; SOE; 201001655; Industrial And Mechanical Engineering; charbel.mansour@lau.edu.lb
    The fuel savings of plug-in hybrid electric vehicles strongly rely on the energy management strategy deployed onboard. For the current mass-produced plug-in hybrid electric vehicles, notably the Toyota Prius, the energy ...
