ENERGY EFFICIENT USAGE OF NATURAL GAS CRITERIAS

Energy, Greenhouse Gas, and Economic Implications of Natural Gas Trucks

Until recently, natural gas was an also-ran in the sweepstakes for changing the face of transportation in the United States, even though expanded reliance on natural gas vehicles (NGVs) holds the promise of reducing carbon emissions, reducing dependence on oil, and even lowering transportation costs. Recently, however, interest in natural gas as a transportation fuel has grown, as shale gas res...

Selection of the Best Efficient Method for Natural Gas Storage at High Capacities Using TOPSIS Method

Nowadays one of the most important energy sources is natural gas. By depletion of oil reservoirs in the world, natural gas will emerge as the future energy source for human life. One of the major concerns of gas suppliers is being able to supply this source of energy the entire year. This concern intensifies during more consuming seasons of the year when the demand for natural gas increases, r...

Opportunistic Sensing for Efficient Energy Usage in Private Households

Reducing datacenter energy usage through efficient job allocation

A large portion of power consumed by datacenters in small and medium sized businesses is wasted consumption, as machines mostly run idle. Commonly, this is accepted by operators as many countermeasures, such as layout redesign or hardware upgrades are too. In this work we analyze how much power can be saved if an exact optimization problem is set up to determine the cost minimizing allocation o...

Efficient estimation of natural gas compressibility factor using arigorous method

The compressibility factor (Z-factor) of natural gases is necessary in many gas reservoir engineering calculations. Accurate determination of this parameter is of crucial need and challenges a large number of used simulators in petroleum engineering. Although numerous studies for prediction of gas compressibility factor have been reported in the literature, the accurate prediction of this param...
