Partition entropy and chi-squared error: the improved MEMPHIS algorithm - Part I
Cubarsí Morera, Rafael; Alcobé López, Santiago (2009-07)
Report de recerca
Accés obertThe 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)
Text en actes de congrés
Accés obertAixí 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. ... -

Small-scale structure of the disc velocity distribution. A maximum entropy statistical approach - Part II
Cubarsí Morera, Rafael (2009-12)
Report de recerca
Accés obertAmong metallicity, colour, and other star properties, the eccentricity of the star’s orbit behaves as a very good sampling parameter to find a more detailed structure for the disc velocity distribution, allowing distinctions ... -
Structure of the velocity distribution of the Galactic disc: a maximum entropy statistical approach - Part I
Cubarsí Morera, Rafael (2009-09)
Report de recerca
Accés obertThe maximum entropy approach is proposed to describe the local structures of the veloc- ity distribution, which are collected through its sample moments. The method is used with several samples from the HIPPARCOS and ... -
