Abstract: The importance of dispersion analysis is paramount in understanding the propagation characteristics of individual component waves in acoustic logging while drilling (ALWD) instrumentation.

it can be obtained by the least action principle, and consequently it possesses a Lagrangian density, it can be obtained by means of the method of multiple scales, thus implying that the NLS equation ...

Optical dispersion occurs when the refractive index of a material changes with the wavelength of incoming light. This variation causes different colors to move at different speeds in transparent media ...

US stock markets have delivered a trading bonanza for investors betting on dispersion – a complex derivatives strategy that profits from share prices heading in different directions – after a ...

Abstract: A rectangular open tape helix is analyzed for its dispersion characteristics that are numerically computed from the dispersion equation derived without any prior assumption of the current ...

The way in which a surface wave propagates (e.g. a Rayleigh wave) on a circumference differs from that of an infinite flat half-space when the wavelengths are comparable to the circumference ($2 \pi R ...

Article Views are the COUNTER-compliant sum of full text article downloads since November 2008 (both PDF and HTML) across all institutions and individuals. These metrics are regularly updated to ...
