Author:Scholes, RJ; Van Breemen, NDate:Sep 1997Alteration of land use will continue to be the dominant driver of environmental change in the tropics for the next several decades. It can take the form of fundamental vegetation cover transformation, or of intensification of existing land ...Read more
Author:Maistry, N; Van Coller, J; Scutz, RADate:Sep 2015It is essential to detect corona discharge as a symptom of insulation breakdown in high voltage (HV) applications. However accuracy of such measurement is often degraded due to the existence of solar background noise in the signal. Fraunhofer ...Read more
