a b s t r a c t introduction: in an oddball experiment, the context in which novel stimuli are presented affects characteristics of novelty p3, i.e. as long as there is a difficult task in which the difference between standard and target stimuli is small, recurrent presentation of a highly discrepant stimulus can lead to p300 highly similar to novelty p3. effect of stimulus properties on p300 h...

A novel geometry for enhancing the sensitivity of intensity modulated refractometric fiber optic sensor for detection of adulteration level in diesel by kerosene is proposed. In this multimode plastic optical fiber is uncladded for specific length and bent into S shape. This geometry is simulated and analyzed using Beam Propagation Method in Beam prop RSOFT software. When sensor is immersed in ...

in this work, a direct design approach for designing a surface shape (inverse design problem) has been developed, in which both the target surface pressure and the unknown nodal coordinates appear explicitly in the formulations. the final discretized form of the governing equations (unified formulation) can be used for both analysis and shape design problems. in this work, shape design problems...

In this article, one-phase and three dimensional computational fluid dynamics analysis was utilized to investigate the effect of annular field pattern of proton exchange membrane fuel cells (PEMFC) with different geometry on the performances and species distribution. This computational fluid dynamics code is used for solving the equation in single domain namely the flow field, the mass conserva...

Since its founding, NASA has been dedicated to the advancement of aeronautics and space science. The NASA Scientiic and Technical Information STI Program OOce play s a k ey part in helping NASA maintain this important role. The NASA STI Program OOce is operated by Langley Research Center, the lead center for NASA's scientiic and technical information. The NASA STI Program OOce provides access t...

In vision and graphics, there is a sustained interest in capturing accurate 3D shape with various scanning devices. However, the resulting geometric representation is only part of the story. Surface texture of real objects is also an important component of the representation and finescale surface geometry such as surface markings, roughness, and imprints, are essential in highly realistic rende...
