Identifying variable gamma-ray sources through radio observations
(Springer, 2005-12)
We present preliminary results of a campaign undertaken with different radio interferometers to observe a sample of the most variable unidentified EGRET sources. We expect to detect which of the possible counterparts of ...
Multi-user PDF estimation based criteria for adaptive blind separation of discrete sources
(Elsevier Science BvAmsterdamHolanda, 2005)
Deeper Chandra follow-up of Cygnus TeV source perpetuates mystery
(IOP Publishing, 2006-12)
A 50 ks Chandra observation of the unidentified TeV source in Cygnus reported by the HEGRA collaboration reveals no obvious diffuse X-ray counterpart. However, 240 pointlike X-ray sources are detected within or nearby the ...
On the nature of the variable gamma-ray sources at low galactic latitudes
(Springer, 2005-12)
Population studies of EGRET gamma-ray sources indicate that there is a distinctive population of bright sources at low galactic latitudes. The sources have a distribution consistent with that of young galactic objects, ...
Use of Escherichia coli BOX-PCR fingerprints to identify sources of fecal contamination of water bodies in the State of Sao Paulo, Brazil
(Academic Press Ltd- Elsevier Science LtdLondonInglaterra, 2012)
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 ...
Open source control device for industry 4.0 based on RAMI 4.0
(2021-04-01)
The technical innovation of the fourth industrial revolution (Industry 4.0—I4.0) is based on the following respective conditions: horizontal and vertical integration of manufacturing systems, decentralization of computing ...
A theoretical analysis of key points when choosing open source erp systems
(TECSI Laboratório de Tecnologia e Sistemas de Informação - FEA/USP, 2011)
The present work is aimed at presenting a theoretical analysis of the main features of Open Source ERP systems, herein identified as success technical factors, in order to contribute to the establishment of parameters to ...
Unidentified γ-ray sources off the Galactic plane as low-mass microquasars?
(Springer, 2005-06)
A subset of the unidentified EGRET γ -ray sources with no active galactic nucleus or other conspicuous counterpart appears to be concentrated at medium latitudes. Their long-term variability and their spatial distribution ...
Perceptually controlled doping for audio source separation
