ltage (I–V) curve tracers are used for measuring voltage and current in pho-tovoltaic (PV) modules. I–V curves allow identifying certain faults in the photovoltaic module, as well as quantifying the power performance of ...

The accurate measurement of shallow flow velocities is crucial to understand and model the dynamics of sediment and pollutant transport by overland flow. In this study, a novel triple-tracer approach was used to re-evaluate ...

For a long time, tracer techniques based on dyes, salts and more recently heat have been used to estimate shallow flow velocities. Traditionally, flow velocity estimation using tracers would consist of tracking the movement ...
