Enabling new techniques in environmental assessment through multi-sensor hydrography
(IEEE, 2016)
A suite of complementary survey tools aimed at producing 1-cm resolution bathymetric models co-registered with 2-mm pixel color photography has been assembled. The design goal is to produce quantitative documentation of ...

(Universidad Nacional de ColombiaManizales - Ingeniería y Arquitectura - Maestría en Ingeniería - Automatización IndustrialFacultad de Ingeniería y ArquitecturaManizales, ColombiaUniversidad Nacional de Colombia - Sede Manizales, 2020)
En este trabajo de tesis se presenta un análisis de sistemas de identificación, localización y seguimiento de personas. Con el fin de medir el flujo de usuarios en las salas de trabajo del laboratorio de Electricidad y ...
Introduction to modern instrumentation: for hydraulics and environmental sciences
(De Gruyter, 2014)
Preface Natural hazards and anthropic activities threaten the quality of the environment surrounding the human being, risking life and health. Among the different actions that must be taken to control the quality of the ...
Aspect sensitivity of equatorial electrojet irregularities and theoretical implications
(American Geophysical Union, 1989-01-01)
We used a multi baseline 50-MHz radar interferometer at the Jicamarca Radio Observatory to study the dependence of echo strength on the aspect angle, the angle of arrival relative to normal to the geomagnetic field. We ...
Anomalous ISR echoes preceding auroral breakup: Evidence for strong Langmuir turbulence
(Blackwell, 2012)
Experimental results obtained with the 449-MHz Poker Flat Incoherent Scatter Radar (PFISR) show unusual features in both the ion line and plasma line measurements during an auroral breakup event. The features are a greatly ...
Naturally enhanced ion-line spectra around the equatorial 150-km region
(European Geosciences Union (EGU), 2009-03-02)
For many years strong radar echoes coming from 140–170 km altitudes at low latitudes have been associated to the existence of field-aligned irregularities (FAIs) (the so called 150-km echoes). In this work, we present ...
