Integrated modelling of potential recharge in small recharge ponds

Arabian Journal of Geosciences, 2019
Integrated models that simultaneously simulate potential recharge and time delay for wetting front to reach water table are necessary for comprehensive and coordinated planning of managed aquifer recharge. Most of the existing models do not simultaneously simulate the potential recharge, length of advancement of wetting front, and time delay for ...

Rechargeable Batteries and Their Management

IEEE Instrumentation & Measurement Magazine, 1998
Publisher Summary The insatiable demand for smaller lightweight portable electronic equipment has dramatically increased the need for research on rechargeable (or secondary) battery chemistries. In addition to achieving improved performance on Lead Acid and Nickel Cadmium (NiCd) batteries, during the last two decades many new chemistries such as ...

Time to recharge

Chemistry in Britain, 2002
Portable electronic devices make up almost half of manufacturing output in the electronics industry. However, as researchers strive to make these devices ever smaller, the battery is the main obstacle to miniaturization. Nickel-cadmium rechargeable batteries used to be favored. However, environmental concerns over the use of cadmium led to the European

Programming wireless recharging for target-oriented rechargeable sensor networks

Proceedings of the 11th IEEE International Conference on Networking, Sensing and Control, 2014
Wireless rechargeable sensors can receive energy from mobile chargers directly. For fulfilling differentiated application requirements, the charger should be programmed in advance to schedule its limited time budget on moving itself and charging individual sensors.

Artificial groundwater recharge, I. Circular recharging area

Journal of Hydrology, 1975
Abstract Artificial groundwater recharge is of increasing importance as an essential component of water-management programs. The fluctuation of the water table in response to recharge depends on the size and shape of the recharging area, on the duration and the type of variation of the recharge rate, and on the hydraulic and geometric parameters of ...

Artificial groundwater recharge, II. Rectangular recharging area

Journal of Hydrology, 1975
Abstract The nonlinear, partial-differential equation characterizing the unsteady flow in an unconfined aquifer receiving uniform vertical recharge from a rectangular spreading basin is solved numerically. The method of solution consists of the alternating-direction implicit scheme with an inhomogeneous grid spacing.
