A Reliable Method to Reduce Observations and Variables
(SABER ULA, 2006)
General two-dimensional least-squares image subtraction
A very general two-dimensional solution to the image convolution problem is presented extending the least-squares approach of Bramich. Image convolution is of wide applicability in astronomical data reduction including, ...
Automated diagnosis of human intestinal parasites using optical microscopy images
Intestinal parasitosis constitutes a serious health problem in most tropical countries. The diagnosis of enteroparasites in laboratory routine relies on the examination of stool samples using optical microscopy and the ...
Bayesian image reconstruction based on Voronoi diagrams
(UNIV CHICAGO PRESS, 2008-01-10)
We present a Bayesian Voronoi image reconstruction ( VIR) technique for interferometric data. Bayesian analysis applied to the inverse problem allows us to derive the a posteriori probability of a novel parameterization ...
Analysis of rhythmic variance - ANORVA. A new simple method for detecting rhythms in biological time series
(Sociedad de Biología de Chile, 2004)
Cross-entropy optimizer: a new tool to study precession in astrophysical jets
(WILEY-BLACKWELL PUBLISHING, INC, 2009)
Evidence of jet precession in many galactic and extragalactic sources has been reported in the literature. Much of this evidence is based on studies of the kinematics of the jet knots, which depends on the correct ...
Calibration and detailed analysis of second-order flow injection analysis data with rank overlap
(Elsevier Science BvAmsterdamHolanda, 2000)
Increasing the efficiency in integer simulation optimization: Reducing the search space through data envelopment analysis and orthogonal arrays
The development of various heuristics has enabled optimization in simulation environments. Nevertheless, this research area remains underexplored, primarily with respect to the time required for convergence of these ...
Low dimensional embedding of climate data for radio astronomical site testing in the Colombian Andes
(IOP Publishing Ltd, 2017)
We set out to evaluate the potential of the Colombian Andes for millimeter-wave astronomical observations. Previous studies for astronomical site testing in this region have suggested that nighttime humidity and cloud cover ...
