DETER-R: An operational near-real time tropical forest disturbance warning system based on Sentinel-1 time series analysis.

Continuous monitoring of forest disturbance on tropical forests is a fundamental tool to support proactive preservation actions and to stop further destruction of native vegetation. Currently most of the monitoring systems in operation are based on optical imagery, and thus are flaw-prone on areas w...

The influence of diethylaniline and toluene on the streamer propagation in cyclohexane between a point-plane gap under positive impulse voltage stress.

Liquid insulation is used in high voltage equipment such as power transformers as both dielectric medium and coolant. Breakdown in liquid insulation tends to be governed either by streamer initiation under more uniform fields, or by streamer propagation under more non-uniform fields. A model streame...

Tropical ecosystem greenhouse gas accounting.

In this chapter, we examine the main components of greenhouse gas budgets from tropical terrestrial and aquatic environments, including how these components are measured and modeled at scales ranging from field plots to regions. We discuss uncertainties associated with measurements and models, revie...
