    A function to data matrix (FDM) approach for mission variables consideration
    (EDP Sciences, 2017-01-01) Fernández-Montoya, M.; Mejía-Gutierrez, R.; Osorio-Gómez, G.
    Precise control of technical system variables in industrial processes and manned and unmanned missions is critical as their results should be achieved plenty. This takes place in Control Rooms (CR) where Operators make decisions based on the large amount of received data. This work proposes a method for weighting variables of a technical system based on their impact on the mission objectives. The relationships between variables and mission functions are defined using a Function to Data Matrix (FDM) in order to allow Operators to determine their criticality. The proposed method was applied for the mission control of the Racing Solar Vehicle Primavera1 which participated in the World Solar Challenge (WSC) 2013 in Australia.

    Influence of epoxy resin as encapsulation material of silicon photovoltaic cells on maximum current
    (EDP Sciences, 2017-01-01) Acevedo-Gómez, D.; Velásquez-López, A.; Osorio-Gómez, G.; Mejía-Gutiérrez, R.
    This work presents an analysis about how the performance of silicon photovoltaic cells is influenced by the use of epoxy resin as encapsulation material with flat roughness. The effect of encapsulation on current at maximum power of mono-crystalline cell was tested indoor in a solar simulator bench at 1000 w/m and AM1.5G. The results show that implementation of flat roughness layer onto cell surface reduces the maximum current inducing on average 2.7% less power with respect to a cell before any encapsulation. The losses of power and, in consequence, the less production of energy are explained by resin light absorption, reflection and partially neutralization of non-reflective coating. © The Authors, published by EDP Sciences, 2017.
