The SAGD start-up process normally circulates steam in both the injector and producer, which consumes a large amount of steam, requires high cost high-temperature-produced liquid treatment, unavoidably results preferential communication heterogeneous reservoirs. In order to achieve uniform preheat full chamber development wellpairs, downhole electrical heating start up was proposed investigated...

In this paper, we introduce a new algebraic structure, called a UP-algebra (UP means the University of Phayao) and a concept of UP-ideals, UP-subalgebras, congruences and UP-homomorphisms in UP-algebras, and investigated some related properties of them. We also describe connections between UP-ideals, UP-subalgebras, congruences and UP-homomorphisms, and show that the notion of UP-algebras is a ...

The line-up task hides a plot of real data amongst decoys built around some plausible null hypothesis. It has been proposed as mechanism for lending greater reliability and confidence to statistical inferences made from graphics. proposition is seductive one, but whether or not line-ups guarantee consistent interpretation structure an open question, especially when applied representations geo-s...
