In oil and gas industry, oil is produced from wells drilled into the oil reservoirs. A thorough understanding and characterization of the subsurface is crucial to sustainable management of a reservoir. The subsurface, however, is largely heterogeneous and oil is not present everywhere. For our study area, the reservoir rock is categorized as three facies: brine sand, oil sand and shale, and it ...

733 Abstract— This paper has studied subthreshold characteristics for double gate(DG) MOSFET using Gaussian function in solving Poisson's equation. Typical two dimensional analytical transport models have been presented for symmetrical Double Gate MOSFETs (DGMOSFETs). Subthreshold swing and threshold voltage are very important factors for digital devices because of determination of ON and OFF. ...

We address the so-called “roll-off” phenomenon: Selective abstention in multiple elections. We present a discuss a novel model of decision making by voters that explains this as a result of differences in quality and quantity of information that the voters have about each election. In doing so we use a spatial model that differs from the Euclidean one, and is more naturally applied to modelling...

The process of applying starch to the warp yarn in order increase weaving power presence a layer, is expected strength and reduce hairs. One factors that influence sizing amount pressure squeezing roll. In this process, machine uses double size box each has 2 (two) rolls. material used Combed Ne 40 with construction ,which tetal or density included dense yarn. method by comparing roll 1 2. firs...

We have assembled and studied melt-processed all-polymer lasers comprising distributed Bragg reflectors that were fabricated in large sheets using a co-extrusion process and define the cavities for dye-doped compression-molded polymer gain core sheets. Distributed Bragg reflector (DBR) resonators consisting of 128 alternating poly(styrene) (PS) and poly(methyl methacrylate) (PMMA) layers were p...

In the fault diagnosis of automaton, the vibration signal presents non-stationary and non-periodic, which make it difficult to extract the fault features. To solve this problem, an automaton fault diagnosis method based on morphological component analysis (MCA) and ensemble empirical mode decomposition (EEMD) was proposed. Based on the advantages of the morphological component analysis method i...

Smart homes generally differ from other pervasive environments such as office environments. Homes are lack of system administrators to fix faulty services on the spot. Nevertheless, services in smart homes can be critical especially when they involve health and wellness services, since faulty services can lead to unexpected/undesirable consequences. Therefore, robustness and availability are tw...
