• A Bio-inspired Plume Tracking Algorithm for Mobile Sensing Swarms in Turbulent Flow 

      Chang, Dongsik; Wu, Wencen; Webster, Donald R.; Weissburg, Marc J.; Zhang, Fumin (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2013-05)
      We develop a plume tracking algorithm for a swarm of mobile sensing agents in turbulent flow. Inspired by blue crabs, we propose a stochastic model for plume spikes based on the Poisson counting process, which captures the ...
    • Diagnosis and Prognosis of Scrubber Faults for Underwater Rebreathers based on Stochastic Event Models 

      Chang, Dongsik; Zhang, Fumin; West, Michael (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2011-06)
      Imperfect CO₂ removal mechanisms of CO₂ scrubbers often lead to the existence of CO₂ in gas inhaled by a diver from underwater rebreathers. This may cause CO₂ related rebreather faults and subsequently would increase ...
