Recent years have brought an explosion in the application of advanced AI techniques to imaging and interpretation petroleum reservoirs. The ability these image features unprecedented detail, within very short timeframes, has provided opportunity for industry gain a more complete understanding hydrocarbon reservoirs than ever before. rapid evolution technologies challenges however, as new workfl...

Background:Several studies have reported the toxicological implications of inhalation of petroleum hydrocarbon fumes in animal models. But, there is certainly little or no documentation of the exposure to petroleum hydrocarbon fuel on oxidative stress levels in humans, unlike the pulmonary physiology. The present study was carried out to evaluate the effects of constituents of the hydrocarbon f...

This literature review paper discusses the subject of lubricating properties liquid hydrocarbon-based fuels and laboratory bench tests applied in lubricity evaluation. The analysis was made order to highlight importance fuel evaluation, especially application relatively rapid tests. Inadequate may lead an excessive wear injection system components some cases ? even catastrophic failure what, tu...

Direct methods have made remarkable progress in the computational efficiency of factorization algorithms during the last three decades. The advances in graph theoretic algorithms have not received enough attention from the iterative methods community. For example, we demonstrate how symbolic factorization algorithms from direct methods can accelerate the computation of a factored approximate in...

Conversational case-based reasoning (CBR) shells (e.g., In-ference's CBR Express) are commercially successful tools for supporting the development of help desk and related applications. In contrast to rule-based expert systems, they capture knowledge as cases rather than more problematic rules, and they can be incrementally extended. However , rather than eliminate the knowledge engineering bot...

UNLABELLED BACKGROUND Historically, acid pretreatment technology for the production of bio-ethanol from corn stover has required severe conditions to overcome biomass recalcitrance. However, the high usage of acid and steam at severe pretreatment conditions hinders the economic feasibility of the ethanol production from biomass. In addition, the amount of acetate and furfural produced during...
