RESULTS FROM THE MACHO GALACTIC PIXEL LENSING SEARCH
(AMERICAN CONCRETE INSTITUTE, 1999)
The MACHO, EROS, OGLE and AGAPE collaborations have been studying nature of the galactic halo for a number of years using microlensing events. The MACHO group undertakes observations of the LMC, SMC and Galactic Bulge ...
3D NON-DESTRUCTIVE EVALUATION TECHNIQUES FOR WOOD ANALYSIS
(IGI GLOBAL, 2014)
Non-destructive testing techniques allow the analysis of wood characteristics without altering its end-use capabilities. Wood morphology, wood density, moisture content, and wood decay are some of the features detectable ...
A NEW NEURAL NETWORK MODEL FOR AUTOMATIC GENERATION OF GABOR-LIKE FEATURE FILTERS
The automatic selection of feature variables is a task of increasing interest in the field of pattern recognition. Neural models have recently been used for this purpose. Among other models, the adaptive-subspace SOM (ASSOM) ...
SCENE-BASED NONUNIFORMITY CORRECTION METHOD USING THE INVERSE COVARIANCE FORM OF THE KALMAN FILTER
(IOS PRESS, 2002)
A scene-based algorithm for nonuniformity correction (NUC) in focal-plane arrays (FPA) detectors has been developed. The NUC technique is based in the inverse covariance form (ICF) of the Kalman filter. The gain and the ...
A MASSIVE PROTOSTAR IN G34.A
(ASTRONOMICAL SOCIETY OF THE PACIFIC, 2001)
Near infrared images of the G34.4 region (IRAS 18507+0121) show a reddened source, detected only in the K' filter, about 15'' in extent. We have recently observed G34,4 with the OVRO array, in the 3mm continuum band and ...
PRE AND POST EARTHQUAKE LAND USE AND LAND COVER IDENTIFICATION IN CONCEPCION
This paper presents the pre and post earthquake identification of representative land cover and land use scenarios in the metropolitan area of Concepción in Chile. Significant land use and land cover changes will be exposed ...
TECHNIQUES ON MESH GENERATION FOR THE BRAIN SHIFT SIMULATION
Neurosurgery interventions involve complex tracking systems because a tissue deformation takes place. The neuronavigation system relies only on pre-operative images. In order to overcome the soft tissue deformations and ...
A FUN APPLICATION OF COMPACT DATA STRUCTURES TO INDEXING GEOGRAPHIC DATA
The way memory hierarchy has evolved in recent decades has opened new challenges in the development of indexing structures in general and spatial access methods in particular. In this paper we propose an original approach ...
RECENT ADVANCES ON FACE RECOGNITION USING THERMAL INFRARED IMAGES
Nowadays it is possible to find several works on face recognition, where principally the visible range spectra is used. In addition, many techniques are tested on different databases and it is possible to identify the best ...
CONFLICTOS Y DIALOGOS EN EL JUDAISMO Y EN EL ISLAM: LOS CASOS DE CHILE Y ARGENTINA
