Borehole seismic methods for opencast coal exploration [PDF]
, 1990 Surface seismic techniques lack the resolution to image the top 100m or so of the earth's surface necessary for opencast coal exploration. The work reported in this thesis is the development of borehole seismic methods making use of the closely spaced ...

Image source detection for geoacoustic inversion by Teager-Kaiser energy operator [PDF]
, 2014 This letter presents an improvement of the image source method (ISM) for geoacoustic inversion. The new algorithm is based on the Teager-Kaiser Energy Operator which ampli es the discontinuities in signals while the soft transitions are reduced.

Post-stack inversion of seismic reflection data from the belvoir coalfield [PDF]
, 1995 Post-Stack inversion of reflection data in seismic exploration can be used to obtain detailed information about lithology variations in the zone of interest. Generalized Linear Inversion (GLI) has previously been applied as a useful tool to achieve this.

A note on the Smarandache inversion sequence [PDF]
, 2007 In a recent paper, Muneer introduced the Smarandache inversion sequence. In this paper, we study some properties of the Smarandache inversion sequence. Moreover, we find the necessary and su±cient condition such that [SI(n)]2 + [SI(n + 1)]2 is a perfect

Slice group based multiple description video coding with three motion compensation loops [PDF]
, 2005 The paper proposes a novel scheme for a multiple description video coding approach using the slice group coding tool proposed in H.264. Three motion compensation loops, one central and two side loops, are maintained for two descriptions in the encoder ...

Analysis of Electron Mobility in Inversion-Mode Al2O3/InxGa1-xAs MOSFETs [PDF]
, 2011 The electron mobility in Al2O3/InxGa1-xAs (x = 0.53, 0.65, or 0.75) metal-oxide-semiconductor field-effect transistors was analyzed for scattering by oxide charge, as well as interface charge and roughness, and compared with measured transfer ...

Geometric Mechanics of the Vertical Slice Model [PDF]
The goals of the present work are to: (i) investigate the dynamics of oceanic frontogenesis by taking advantage of the geometric mechanics underlying the class of Vertical Slice Models (VSMs) of ocean dynamics; and (ii) illustrate the versatility and ...
