    • A Metric Index for Approximate String Matching 
      Navarro, Gonzalo; Chávez, Edgar (Elsevier, 2006)

    • Microclimate modification under the effect of stationary and portable wind machines 
      Beyá-Marshall, Víctor; Herrera, Julio; Santibáñez, Fernando; Fichet, Thomas (Elsevier B.V., 2019)
      Frosts are one of the most harmful weather events, causing recurrent and great damage in agriculture. Active control methods, such as wind machines, must be implemented to reduce the impact on crops. A new portable wind ...
    • Microeconomic model of residential location incorporating life cycle and social expectations 
      López Ospina, Héctor A.; Martínez, Francisco J.; Cortés Carrillo, Cristián (Elsevier, 2016)
      This paper is focused on the dynamics of residential location decisions based on the microeconomic theory of urban land use, inwhich we assume that each property is assigned to the agent with the highest bid. The ...
