Today, the agricultural sector world over is confronted with a water scarcity crisis and related numerous challenges. Harnessing scarce resources to meet irrigation requirement in more economical way without compromising sustainability very vital. The present study aims at applying EPANET2.2, hydraulic modelling tool, optimization design of solar-powered direct pumping sprinkler system. This ha...

In order to implement an integrated optical quantum circuit, designing waveguides based on the quantum box is of prime importance. To do this we have investigated optical waveguide both with and without optical pumping. The rate of absorption and emission using an array of AlGaAs/GaAs quantum box core/shell structure in the optical waveguide with various pumping intensities has computed. By con...

in this research using the theory of induction motor (um), a um with liquid as secondary part is planned and manufactured. the main objective for planning of this motor is to investigate the possibility of chemical liquids pumping such as liquid poison and acids. results of many laboratory tests are shown to conclude that pumping force in the manufactured pump is dependent on many factors su...

During the pumping of wells, groundwater level drawdown, as measured in pumped well, is increased by non-linear losses caused water flow velocity through well screens. This undermines adequacy direct use drawdown data for purpose realistic identification effective radius and aquifer parameters. anomaly avoided reshaping function into a specific sw/Q well. simplifies exclusion from sequence at p...

LVAD is a mechanical pump supporting a weak heart function and blood flow. Sometimes, the heart may not recover fast enough to take over the pumping action immediately after surgery, in such patients a temporary support device has been employed to maintain the pumping action until the patient’s own heart recovers. This device can be considered as a temporary alternative before the process of ar...

We study theoretically and experimentally the spin pumping signals induced by resonance of canted antiferromagnets with Dzyaloshinskii-Moriya interaction demonstrate that they can generate easily observable inverse spin-Hall voltages. Using a bilayer hematite/heavy metal as model system, we measure at room temperature antiferromagnetic an associated voltage, large in collinear antiferromagnets....

water conveyance through pumping takes a lot of energy and cost and therefore, its application should be accompanied by exact design of pumping station as well as correct positions of pumps and their subsidiary apparatus. sumps are designed for many pumping stations and often face the problems of vortex and irregular flows. therefore an investigation of the general flow pattern in sumps in diff...

The main asset of this paper is among the uses of fuzzy logic in the engineering sector and especially in the renewable energies as a large alternate of fossil energies, in this paper a PSO-based optimization is used to find the optimal scaling parameters, of a fuzzy logic-based MPPT controller, that maximize the efficiency of a photovoltaic pumping system. The tuning of input and output parame...
