    Conference report
    Open Access
    Bacterial inclusion bodies are microscopic, ovoid-shaped aggregates of insoluble protein. Under protease exposure a digestion process is produced that reveals a variable fragmentation rate, not compatible with a surface ...

    Conference lecture
    Open Access
    The determination of stellar population constants from the statistics of a global sample is extremely sensitive to the noise introduced by a few non-typical stars. The local velocity distribution can be better determined ...

    Cubarsí Morera, Rafael (2008-12-01)
    External research report
    Open Access
    The maximum entropy approach is used to solve the classical moment problem of stellar kinematics. If an extended set of moments is available, the current method provides a linear estimation algorithm, which is given ...

    Conference report
    Open Access
    Determination of stellar population parameters from statistics of global samples is extremely sensitive to the noise introduced by few non-typical stars. In order to obtain a nearly-pure two-population mixture a subsample ...
  • Partition entropy and chi-squared error: the improved MEMPHIS algorithm - Part I 

    Cubarsí Morera, Rafael; Alcobé López, Santiago (2009-07)
    External research report
    Open Access
    The entropy of the population partition is studied as a function of the sampling parameter, so that within a particular interval of its graph, the plateau region, it is possible to get a stable estimation of the mixture ...
  • Principi de conservació del desenvolupament sostenible i el software lliure 

    Cubarsí Morera, Rafael; Escudero Royo, Miguel (Centre per a la Sostenibilitat, 2009-07-09)
    Conference report
    Open Access
    Així com l'energia total d'un sistema mecànic és la suma de l'energia cinètica i la potencial, podem dir que el desenvolupament en sostenibilitat és la suma 'ús de recursos' més ‘potencialitat d’ús’, en la justa mesura. ...
