The gas-lifted system has inherent ability to hide the effect of fault hence can inject gas into annulus and oil will still be produced even in presence significant value. This however affects optimal operation could move towards undesirable casing-heading instability. Faults step decrease valves coefficients addition limitation on valve affect flow liquids through system. We detect isolate the...

Studies on remote, uninhabited, near-pristine reefs have revealed surprisingly large populations of large reef fish. Locations such as the northwestern Hawaiian Islands, northern Marianas Islands, Line Islands, U.S. remote Pacific Islands, Cocos-Keeling Atoll and Chagos archipelago have much higher reef fish biomass than islands and reefs near people. Much of the high biomass of most remote ree...

Despite increasing reports of fisheries collapses world wide, investigations of the effects of fishing on the global marine environment have been constrained by the paucity of fisheries landings data on suitable spatial scales. Working to overcome this, we have developed new databases and approaches that demonstrate basin-scale reductions in biomass and landings due to intensifying fishing effo...

In the recent years, resource depletion of inshore and coastal fisheries has seriously impacted Taiwan. Local fishing communities’ economic profits in these fisheries have declined and resulted in lower earned incomes for the fishermen. These phenomena have lead many scholars, government agencies and fishing communities to evaluate the optimal number of operating vessels in these fisheries. Thi...

We have conducted a comparison between three types of recurrent neural networks and their ability to predict anomalies occurring in oil wells using publicly available dataset. included two well-known state-of-the-art new type with neurons evolved specifically for the dataset automatic programming. show that neuron offers massive improvement over state-of-the-art. The overall test accuracy netwo...
