Adaptive sampling for environmental robotics [PDF]

IEEE International Conference on Robotics and Automation, 2004. Proceedings. ICRA '04. 2004, 2004
The capabilities and distributed nature of networked sensors are uniquely suited to the characterization of distributed phenomena in the natural environment. However, environmental characterization by fixed distributed sensors encounters challenges in complex environments.

Trace Level Arsenic Quantification through Methyl Red Bromination [PDF]

, 2012
A simple protocol has been developed for the quantification of trace level arsenic through methyl red bromination. The proposed method is based on the oxidation of arsenic(III) to arsenic(V) by the bromine and the residual bromine’s reaction with methyl ...
