02/10/2012---with the help of Dan

      • We had a discussion presenting crowd dynamics from a microscopic behavior perspective, and how we can potentially use fractional calculus to model the differences, while eliminating computational complexities typically found in the agent based approach.    
      • One concept discussed was the use of distributed ordered systems, with their properties of changing parameters against spatial change, see examples discussed in the paper: Variable Order and Distributed Order Fractional Operators;
      • We also cite some discussions involving fractional diffusion through porous mediums.
