The aim of this WP5 is to specify the impact of TID in EGNOS, N-RTK and HF systems through statistical correlation of the performance data recorded from system operators and of TID detection results. The analysis will be ...
Structure of the velocity distribution of the Galactic disc: a maximum entropy statistical approach - Part I
(2009-09)
Report de recerca.
Accés obert
Report de recerca.
Accés obert
The 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 ...
Small-scale structure of the disc velocity distribution. A maximum entropy statistical approach - Part II
(2009-12)
Report de recerca.
Accés obert
Report de recerca.
Accés obert
Among 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 ...
On the maximum entropy and the problem of moments: an application to stellar kinematics
(2008-12-01)
Report de recerca.
Accés obert
Report de recerca.
Accés obert
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 ...
Partition entropy and chi-squared error: the improved MEMPHIS algorithm - Part I
(2009-07)
Report de recerca.
Accés obert
Report de recerca.
Accés obert
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 ...
Classification of local stellar populations: the improved MEMPHIS algorithm - Part II
(2009-07)
Report de recerca.
Accés obert
Report de recerca.
Accés obert
Discontinuities of the local velocity distribution which are associated with stellar populations
are studied from the improved statistical method MEMPHIS (Maximum Entropy of
the Mixture Probability from HIerarchical ...
