Analyzing the feasibility of a space-borne sensor (SPOT-6) to estimate the height of submerged aquatic vegetation (SAV) in inland waters
(2018-10-01)
Remote sensing based approaches have been widely used over the years to monitor and manage submerged aquatic vegetation (SAV) or aquatic macrophytes mainly by mapping their spatial distribution and at the most, modeling ...
Ultrasonic sensor for the presence of oily contaminants in water
(UNIV NAC COLOMBIA, FAC NAC MINASMEDELLIN, 2012)
The determination of the complex reflection coefficient of ultrasonic shear-waves at the solid-liquid interface is a technique employed for the measurement of the viscoelastic properties of liquids. An interesting property ...
Geophysical surveys on permafrost in Coropuna and Chachani volcanoes (southern Peru)
(Copernicus, 2015)
A network of air and ground temperature sensors installed 2004-2014 has enabled the discovery of permafrost on the Coropuna (6377 m) and Chachani (6057 m) volcanoes. However, on the Misti (5820 m) volcano there is no ...
Registro global de nuvens de pontos RGB-D em tempo real usando fluxo óptico e marcadores
(Universidade Federal do Rio Grande do NorteBrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM ENGENHARIA ELÉTRICA E DE COMPUTAÇÃO, 2015-07-31)
Registration of point clouds captured by depth sensors is an important task in 3D reconstruction applications based on computer vision. In many applications with strict performance requirements, the registration should be ...
In-depth understanding of the relation between CuAlO2 particle size and morphology for ozone gas sensor detection at a nanoscale level
(American Chemical Society - ACSWashington, DC, 2014-12)
A morphology-dependent nanomaterial for energy and environment applications is one of the key challenges for materials science and technology. In this study, we investigate the effect of the particle size of CuAlO2 ...
