A multi-wavelength survey of AGN in the XMM-LSS field. I. Quasar selection via the KX technique
(2009)
Aims. We present a sample of candidate quasars selected using the KX-technique. The data cover 0.68 deg2 of the X-ray Multi-Mirror (XMM) Large-Scale Structure (LSS) survey area where overlapping multi-wavelength imaging ...
Selection of energy matrix sources in Chile using a fuzzy logic decision approach.
Chile’s 2050 energy policy ultimate goals are to produce a sustainable model of economic growth respectful of the environment where energy is produced efficiently and reliably. Renewable energy sources are considered the ...
The Chandra Deep Field-South Survey: 4 Ms Source Catalogs
(2011)
We present point-source catalogs for the 4Ms Chandra Deep Field-South (CDF-S), which is the deepest Chandra survey to date and covers an area of 464.5 arcmin^2. We provide a main source catalog, which contains 740 X-ray ...
Influence of ABS print parameters on a 3D open-source, self-replicable printer
(2020-01-01)
Purpose: The purpose of this paper is to investigate and discuss the influence of printing parameters on the mechanical properties of acrylonitrile butadiene styrene (ABS) print by fused deposition modelling (FDM). The ...
Multifunctional current reference generation strategy for grid-tied power electronic converter
(2015)
In this work the functionalities of Power Electronic Converters (PEC) used as grid interface device for distributed generation sources are extended to deal with Power Quality (PQ) issues. It is proposed an alternative ...
A cluster based hybrid feature selection approach
(Universidade Federal do Rio Grande do Norte – UFRNSociedade Brasileira de Computação – SBCNatal, 2015-11)
Data collection and storage capacities have increased significantly in the past decades. In order to cope with the increasingly complexity of data, feature selection methods have become an omnipresent preprocessing step ...
Mid-Infrared Properties and Color Selection for X-Ray-Detected Active Galactic Nuclei in the MUSYC Extended Chandra Deep Field-South
(2008)
We present the mid-infrared colors of X-ray-detected AGNs and explore mid-infrared selection criteria. Using a statistical matching technique, the likelihood ratio, over 900 IRAC counterparts were identified with a new ...
Selection index with parents, populations, progenies and generations effects in autogamous plant breeding
(Crop Science Society of America, 2018)
Influence of the protein status of piglets on their ability to select and prefer protein sources
(Elsevier, 2014)
Pigs may have retained the capacity to choose feeds based on their nutritional requirements, even after decades in which they are not allowed to select their diet composition due to the common feeding systems of the intensive ...
