Improved Prediction of Fluid Contacts using Calibrated Material Balance Models
Abstract: The demand for oil has been on the high in the recent past and will continue as search for sustainable alternative energy sources intensifies. The exploration and exploitation of oil from subsurface reservoirs have posed several environmental challenges which include flaring and improper water disposal to name a few, caused by excessive production of gas and water. Hence, it is important to establish a reservoir performance monitoring scheme that will …

A Survey of Haptic Feedback Integration in Mobile Devices
Abstract: “HAPTICS is a technique that gives virtual environments a tactile element. With haptic interfaces, we may create the impression that we are feeling surfaces, manipulating virtual clay, or moving objects around on a computer in addition to seeing them. Because touch is the brain's most powerful learning mechanism—more so than sight or sound—the new technology has enormous potential for use in education. Using haptic technology is similar to using a …

Modelling of Skin Effect in On-Chip VLSI RLC Global Interconnect
Abstract: This paper addresses one of the aspects of the high frequency effects, namely the skin effect. The basicproblem with skin effect is that it attenuates the high frequency components of a signal more than that ofthe low frequency components. Due to the increase in operating frequency and die sizes, RC models arebecoming insufficient for analysis of global VLSI interconnects. Accurate noise modelling for RLC lines isthus critical for timing and …

Radial Basis Function Neural Networks for Rainfall-Runoff Modeling
Abstract: Rainfall-runoff process is purely nonlinear and varies spatially as well as temporally. Any hydrological model requires many parameters which represent different components of the process. Availability of all the parameters is difficult for any catchment and probabilistic generation of such type of data is impossible. Under such circumstances, artificial neural networks (ANNs) have proven to be a better tool to model the rainfall-runoff process with minimum available data. The present …
