Oil-water two-phase flow widely exists and its measurement is of significance in oil well logging, oil transportations and etc. One of the techniques in common use in oil-water two-phase flowrate measurement is the Differential Pressure (DP) meters combining a theoretic model connecting the mass flowrate of the mixture with the differential pressures generated by the throttling element inside t...

Utility companies collect usage data from meters on a regular basis. The are collected automatically using radio-frequency identification (RFID) technology. Each meter transmits signals an RFID tag that read by vehicle-mounted reading device within specified distance. Routing the vehicles can be modeled close-enough vehicle routing problem street network. In practice, there is uncertainty while...

The widespread deployment of smart meters for electricity gas and water consumption to modernise the electricity systems, has been associated with privacy concerns. In this paper, we present protocols that can be used to privately compute aggregate meter measurements, allowing for fraud and leakage detection as well as further statistical processing of meter measurements, without revealing any ...

AIMS This study assessed the cost efficacy and cost utility of the automatic blood glucose meter CONTOUR(®) TS from the public payer (National Health Fund [NHF]) and payer (patient and NHF) perspectives over a 26-year analysis horizon. METHODS Clinical effectiveness data were obtained from prior clinical studies of automatic versus manually coded blood glucose meters. Cost data were obtained ...

We have produced annual estimates of national and global gas flaring and gas flaring efficiency from 1994 through 2008 using low light imaging data acquired by the Defense Meteorological Satellite Program (DMSP). Gas flaring is a widely used practice for the disposal of associated gas in oil production and processing facilities where there is insufficient infrastructure for utilization of the g...

Utilities and Manufacturers continually deploy new technologies on their systems with the goal of either providing new functionality or improving reliability. Although these devices can be tested in the lab, these results need to be confirmed by field experience. The traditional anonymous Control group approach is often not possible in the Utility context as installations are made when possible...

The oil and gas industry is truly global, with operations conducted in every corner of the world, since the worldwide increasing of energy demand has strongly raised the exploitation of non-renewable resources. The date of birth of the offshore industry is commonly regarded as 1947, when it was successfully completed by Kerr-McGee the first well in the Gulf of Mexico (Chakrabarti et al., 2005)....

The most popular way to improve consumers’ control over their electricity cost is by providing frequent and detailed feedback with “in-home displays” (IHD). In this study, we examined alternative ways to train experimental participants to control and optimize their use of electricity by “feedforward” training to map energy consuming behaviors to costs. The participants were trained in one of fo...
