—We analyze the problem of localization algorithms for underwater sensor networks. We first characterize the underwater channel for radio communications and adjust a linear model with measurements of real transmissions. We propose an algorithm where the sensor nodes collaboratively estimate their unknown positions in the network. In this setting, we assume(More)
Simulation has been widely applied to health care cases in numerous countries. In Colombia, these applications are scarce. We use a systemic approach, discrete event simulation, simulation-optimization and linear programming to reduce waiting times in a health center in Medellín, Colombia. With this reduction we ensure a high level of satisfaction of(More)
