Small embedded systems operating in unattended conditions do need to be perpetually powered if a truly pervasive paradigm is envisaged. Harvesting energy from the surrounding environment seems to be the best option. For that, a set of systems has been proposed featuring interesting solutions but not yet capable of overcoming some issues like performance and flexibility. The authors propose a no...

This paper presents a systematic design methodology for impedance matching circuits of an RF energy harvester to maximize the harvested energy for a range of input power levels with known distribution. Design of input matching networks for RF rectifier differs from those for traditional RF circuits such as low-noise amplifier because the transistors in the RF rectifiers operate in different reg...

This research is an integration of GIS and multi-criteria decision making into a joint framework for identifying suitable areas for rainwater harvesting structures. The Kavir National park in Iran has been evaluated for suitability of rainwater harvesting. To this end, slope gradient, distance to guarding stations, distance to watering points for transporting collected water, distribution of wi...
