virtual source

virtual source

[′vər·chə·wəl ′sȯrs]
(acoustics)
A source of sound which is composed of the same material as that in which the sound propagates and which does not have sharply delineated boundaries; such sources include thermal sources (such as lightning and thermoacoustic arrays), turbulence (as in rocket and jet engines), and sound itself (as in a parametric acoustic array).

All of the functionality in legacy Pathfinder software has been improved upon, the company says, including customizable user panels, automatic table generation, virtual source routing, and Memory Slotsthat allow you to make decisions based on custom pieces of information.
They included the latest innovation of full matrix capture (FMC), and virtual source aperture (VSA) and the latest advancements in automated inspection, enabling accurate and detailed inspection of components with complex geometry.
Philippine Trade Commissioner Michael Ignacio also unveiled the collaboration between the Philippine Trade & Investment Center in Silicon Valley and One Virtual Source to create onevirtualsource.
To reproduce a spherical wavefront emanating from a virtual source S, the input current of the m'th x-directed dipole in the PA is chosen as:
Cloud computing is simply defined as access to processing power from a virtual source.
Allow all data sources to act as a single virtual source, making it easier to deliver data in multiple ways for different consumers.
In this paper, in order to overcome the drawbacks of SBR method and IT and retain their merits, a RT method for the calculation of radio coverage in urban microcellular environment using the new virtual source tree, which is based on the numerical simulation of geometrical optics (GO) and UTD and can solve some of the problems that other RT methods have, is presented.
A sampling of topics: virtual source applications to imaging and reservoir monitoring, long-range correlations in the diffuse seismic coda, P-waves from crosscorrelation of seismic noise, spurious multiples in seismic interferometry of primaries, and time-reversal acoustics in complex environments.
The key idea is that a direct path from each virtual source has the same directionality and length as a specular reflection path.
Source locations were performed by 1) determining arrival sequence of Lamb waves to the three sensors using the resonance frequencies, 2) finding arrival time differences of A0-mode at a selected frequency (120 kHz) and 3) scanning for a virtual source utilizing the constant group velocity of 1280 m/s for this frequency.
These results indicate that in order to prevent localization errors with the 3D auditory display, the sound produced by the virtual source should have a relatively long duration and head movements should be allowed.
3 can hook into existing provisioning solutions, such as SailPoint, providing the benefit of workflow and business logic with the added bonus of a one-stop connection to a virtual source.
