Research ArticleOpen accessIn the abstractGreen Methodologies to Test Hydrocarbon ReservoirsFrancesca Verga, Vera RoccaProblem statement: The definition and the economic viability of the best development strategy of a hydrocarbon reservoir mainly depend on the quantity and type of fluids and on the well productivity. Well testing, consisting in producing hydrocarbon to the surface while measuring the pressure variations induced in the reservoir, has been used for decades to determine the fluid nature and … …American Journal of Environmental Sciences, Vol. 6, Issue 1 · 28 Feb 2010 · 7,643 accessesView PDFCite
Research ArticleOpen accessIn the abstractLand Cover Change Detection Using Texture AnalysisXiaofeng Wu, Fen Yang, Roly LishmanProblem statement: It is an important task to detect land cover changes from remotely sensed data for environmental monitoring. Although there are some applications of visual textures to the land use, they are limited to a few land cover categories with the application of one texture measure. Since land cover types are complex and often the integration of various objects, … …Journal of Computer Science, Vol. 6, Issue 1 · 31 Jan 2010 · 8,203 accessesView PDFCite
Research ArticleOpen accessIn the abstractRelationship between Affordances in the Home Environment and Motor Development in Children Age 18-42 MonthsAlireza Haydari, Parviz Askari, Maryam Zarra NezhadProblem statement: Environmental stimulation plays a critical role in optimal human development during the early stages of life and an optimal level (of development) occurs with strong contextual support. It is well accepted among develop mentalists that motor-perceptual-and cognitive development are fundamentally interrelated. This suggests that status of motor development is an important factor in overall child well-being.
