Finance Minister of India, in 2007 Government of India launched the Dug Well Recharge Scheme as a national program with an outlay of Rs. 1800 crore. Its aim was to educate and incentivize farmers in 100 hard rock districts of the country to modify their open dug wells for groundwater recharge. However, after around 3 years of operation of the scheme, our review found that it failed to achieve m...

Energy harvesting is the process of capturing energy existing in the environment of a wireless device in order to power its electronics without the need to manually recharge the battery. By replenishing on-board energy storage autonomously, the need to recharge or replace the battery can be eliminated altogether, enabling devices to be placed in difficult-toreach areas. Vibration-based energy h...

Groundwater recharge estimates are required for the management of river basin districts under the new Water Framework Directive. Different recharge estimation techniques are described in this paper according to the following categories: inflow estimation, aquifer response analysis, outflow estimation and catchment water balance. Examples of their application in Ireland are provided. All estimat...

Basinwide very low-frequency (VLF) modes with zonal uniformly deepening and shoaling of the equatorial thermocline are found as solutions of linear shallow-water equations with the meridional basin boundaries under an equatorial b plane. They can be understood as the free heat-content recharge oscillations. The interannual VLF modes had been recognized as the essential part of the coupled recha...

Recently, special attention has been paid to artificial groundwater recharge in water resource management in arid and semi-arid regions. Water resources distribution in these regions is extremely uneven, both in spatial and temporal forms and groundwater is the only water resource and is a major constraint on economic and social development. Artificial groundwater recharge is considered an appr...

[1] Eastern Pacific sea surface temperature (SST) and mean equatorial Pacific thermocline depth are key variables in El Niño–Southern Oscillation (ENSO). A linear fit to observations leads to a remarkably simple picture: ENSO can be represented by a classical damped oscillator, with SST and thermocline depth playing the roles of momentum and position, respectively. An independent fit of observe...

It is often challenging to manage the battery supply when dealing with a fleet of mobile robots during long experiments. If one uses classical recharge stations, then agents are immobilized during the whole recharge process. In this study, we present a novel approach that employs a battery pack swapping station. Batteries are charged in a rotating barrel, and the robots dock only for the time o...

We consider the setting of a sensor that consists of a speedscalable processor, a battery, and a solar cell that harvests energy from its environment at a time-invariant recharge rate. The processor must process a collection of jobs of various sizes. Jobs arrive at different times and have different deadlines. The objective is to minimize the recharge rate, which is the rate at which the device...
