In the context of metric perturbation theory for non-spinning black holes, extreme mass ratio binary (EMRB) systems are described by distributionally forced master wave equations. Numerical solution o...
Solute Transport Measurements in Different Soil Types using Time Domain Reflectometry
Transport Measurements Soil Types Time Domain Reflectometry
2009/10/23
During recent years, time domain reflectometry (TDR) has proved to be a valuable tool for both water content (θ) and bulk electrical conductivity (σa) measurements. To allow resident solute concentrat...
Calibration of Time Domain Reflectometry for Water Content in Peat Soil
Time Domain Reflectometry Water Content Peat Soil
2009/10/22
Since peat soil differs from mineral soil in several respects, mineral-soil calibration
functions for time domain reflectometry (TDR) are not necessarily applicable.
This paper evaluates a number of...
