a key parameter for the application of polymer gels in water shut off treatment is the adsorption of polymer gel onto the rock surface. so, the adsorption properties of a nanocomposite hydrogel were discussed in this research by crosslinking of sulfonated polyacrylamide/sodium montmorillonite aqueous solutions with chromium triacetate. the x-ray diffraction patterns indicated that exfoliated ty...

This work presents a prototype of an implantable drug delivery system that delivers pulsed doses of a low solubility drug by pulling bodily fluid into a reservoir with the drug in solid form, allowing the drug to dissolve to its maximum co ncentration, and then ejecting the drug laced fluid back into the tissue. The cyclical actuation of the drug delivery sy stem is performed using an electroly...

Over the last two decades West Nile Virus (WNV) has been responsible for significant disease outbreaks in humans and animals in many parts of the World. Its extremely rapid global diffusion argues for a better understanding of its geographic extent. The purpose of this inquiry was to explore spatio-temporal patterns of WNV using geospatial technologies to study populations of the reservoir host...

Classiier systems have traditionally used explicit measures of utility (strength, predicted payoo, accuracy, etc.) to quantify the performance and tness of classiier rules. Much of the eeort in designing and implementing these systems has focused on getting these utilities \right". One alternative worth exploring is the idea of using endogenous t-ness; that is, reinforcing successful performanc...

This paper proposes a method for quantitative integration of seismic (elastic) anisotropy attributes with reservoir performance data as an aid in characterization of systems of natural fractures in hydrocarbon reservoirs. This method is demonstrated through application to history matching of reservoir performance using synthetic test cases. Discrete Feature Network (DFN) modeling (Dershowitz et...

Reservoir computing is a novel bio-inspired computing method, capable of solving complex tasks in a computationally efficient way. It has recently been successfully implemented using delayed feedback systems, allowing to reduce the hardware complexity of brain-inspired computers drastically. In this approach, the pre-processing procedure relies on the definition of a temporal mask which serves ...

A new group of breathing systems, namely the Enclosed Afferent Reservoir (EAR) systems, is described. They allow for the selective elimination of alveolar gas in association with both spontaneous and controlled ventilation. A comparison with the Bain system in controlled ventilation demonstrates greater efficiency in eliminating carbon dioxide. A fresh gas flow (VF) of 70 ml kg-1 min-1 using an...

In this paper we present a novel framework for better modeling uncertainty in complex systems and demonstrate the approach applied to regulated river systems. In this framework, only the stream inflows are assumed to be purely stochastic. Other uncertain quantities are correlated to the uncertainty of the stream inflows using the dynamics of the river as the physical description of the system. ...

The objective of this research is to introduce a novel framework quantify the risk reservoir system outside design envelope, taking into account risks related flood-protection and hydro-energy generation under unfavourable element conditions (system failures) hazardous situations within environment (flood event). To analyze water behavior in adverse conditions, analysis approach used, which fou...
