Field Spectroscopy for Assisting Water Quality Monitoring and Assessment in Water Treatment Reservoirs Using Atmospheric Corrected Satellite Remotely Sensed Imagery

Remote Sensing, 2011
The overall objective of this study was to use field spectro-radiometers for finding possible spectral regions in which chlorophyll-a (Chl-a) and particulate organic carbon (POC) could be identified so as to assist the assessment and monitoring of water ...

Ecuaciones cuadráticas y procedimientos algorítmicos. Diofanto y las matemáticas en Mesopotamia

THEORIA, 2008
En este ensayo presento un análisis comparativo entre los diversos procedimientos creados, respectivamente, por los matemáticos babilonios y Diofanto de Alejandría para resolver ecuaciones de segundo grado. Observaremos cómo los primeros recurrieron a la composición de diagramas mientras Diofanto aplicó un algoritmo abstracto que no consiguió ...
