Smart well technology is attracting increasing attention because it promises to add operation flexibility and potentially increases oil recovery. However, it remains difficult to find the best strategy for production optimization. One challenge is to find a good optimization algorithm, as some optimization algorithms require prohibitive work to compute the gradients of the objective function wi...

In radio, multiple-input and multipleoutput (MIMO), is the use of multiple antennas at both the transmitter and receiver to improve communication performance. Multiple antennas may be used to perform smart antenna functions such as spreading the total transmit power over the antennas to achieve an array gain that incrementally improves the spectral efficiency. In this paper the water filling al...

Here's the problem with that figure: It's off by a factor of at least 10. They don't call the large fabric planting containers most growers use these days “smart pots” for nothing. They permit the plant to use soil and water far more efficiently. Using a drip irrigation system, Benno prefers to water his plants three gallons once every three days. This is in line with other growers I've talked ...

The conversion of grass lawns to xeriscape has become more prevalent in the desert Southwest, including here in the Las Vegas Valley. The purpose of this thesis was to determine whether the conversion of residential landscapes from grass lawn to xeriscape influences the property value of a home. This case study involved the comparison of property values for residential homes that had participat...

The precious irrigation is great significance for arid and semiarid area. According to the special environment of greenhouse, a fuzzy control algorithm was proposed to make an optimal irrigation strategy based on the actual measured soil humidity during the whole plant growth process. The fuzzy control system had two inputs (soil humidity error and its rate) and one output (water level differen...

A new family of hierarchically helical carbon-nanotube fibers with many nano- and micro-scale channels has been synthesized. They demonstrate remarkable mechanical actuations in response to water and moisture. The water or moisture is first rapidly transported through the trunk micron-scale channels and then efficiently infiltrates into the interconnected capillary nanoscale channels, similar t...

A campus based smart micro grid model that combined power and heat is presented. In this study, optimal scheduling of distributed generations inside these smart micro grids is determined based on demand forecasting, solar power forecasting and wind power forecasting by artificial neural network (ANN). The proposed model is then evaluated through economical efficiency, environment efficiency and...

Today, by using half of the oil reserves of the world, natural production of oil has decreased drastically. Gas and water injection for maintaining reservoir pressure is not responsive for oil production.At first, we dispersed silica nanoparticles in low salinity and after two weeks, there was no change in its stability. Then we mixed the nanoparticles in low salinity. After a while, we found o...

Ensuring the reliable and continuous operations of complex, unpredictable, and unstable smart infrastructures, such as computerized and automated power grids or water distribution systems, is a persisting organizational challenge and a societal concern. As technologies are inherently unreliable and, especially, the behavior of complex technological systems is unpredictable, the reliability and ...

This paper is devoted to a recently running project with a purpose of getting some useful feedback from the interested community. The main point of the project is an attempt to apply approaches developed in the scope of the Ambient Intelligence area and usually implemented indoor (eg., intelligent homes) also in various fields suitable for largescale outdoor activities (esp. working) applicatio...
