Combining cosmological constraints from cluster counts and galaxy clustering
Present and future large scale surveys offer promising probes of cosmology. For example the Dark Energy Survey (DES) is forecast to detect ~300 millions galaxies and thousands clusters up to redshift ~1.3. I here show ...
Data analysis in python: Anonymized features and imbalanced data target
Remaining useful life (RUL) of an equipment or system is a prognostic value that depends on data gathered from multiple and diverse sources. Moreover, assumed for the sake of the present study as a binary classification ...
Sustainable development in the BRICS countries: an efficiency analysis by data envelopment
(Taylor & Francis Inc, 2014-06-01)
There is much concern about the social and environmental impacts caused by the economic growth of nations. Thus, to evaluate the socio-economic performance of nations, economists have increasingly addressed matters related ...
On data analysis in PTR-TOF-MS: From raw spectra to data mining
(Elsevier Science, 2011-07)
Recently the coupling of proton transfer reaction ionization with a time-of-flight mass analyser (PTRTOF-MS) has been proposed to realise a volatile organic compound (VOC) detector that overcomes the limitations in terms ...
Kinematic parameters and membership probabilities of open clusters in the Bordeaux PM2000 catalogue
(EDP SCIENCES S A, 2010)
Aims. We derive lists of proper-motions and kinematic membership probabilities for 49 open clusters and possible open clusters in the zone of the Bordeaux PM2000 proper motion catalogue (+ 11 degrees <= delta <= + 18 ...
Analysis of the Bayesian Cramer-Rao lower bound in astrometry Studying the impact of prior information in the location of an object
(EDP Sciences, 2016)
Context. The best precision that can be achieved to estimate the location of a stellar-like object is a topic of permanent interest in the astrometric community. Aims. We analyze bounds for the best position estimation ...
Análise de séries temporais de coordenadas estimadas com GPS: uma proposta metodológica para detecção, remoção e recuperação de efeitos sazonais
(Universidade Federal do Paraná (UFPR), Centro Politecnico, 2009-10-21)
GPS active networks are more and more used in geodetic surveying and scientific experiments, as water vapor monitoring in the atmosphere and lithosphere plate movement. Among the methods of GPS positioning, Precise Point ...
