Most of the research in music information retrieval (MIR) is concentrating only on monophonic source signals. The stereo information has been ignored largely in the research many years. However, commercially available music recordings typically consist of a two-track stereo mix. The type of mixing process used in the recordings can be roughly categorizes into live recordings and studio recordings.
one of the limitations of orthogonal frequency division multiplexing (ofdm) in many applications is its sensitivity to frequency shifts, errors normally referred to as carrier frequency offset (cfo). although, this small offset is negligible in conventional single carrier communication systems, it is a severe problem in the ofdm systems. because, the carriers in ofdm are inherently closely spac...
The work presented here describes a novel fracture characterization technique that utilizes azimuthal amplitude variations (AVAZ) present in 3D seismic data to deduce subsurface fracturing characteristics. We apply this technique to both synthetic data and real data from the Haynesville Shale. The method we propose is able to unambiguously invert for fracture azimuth, and does not suffer from a...
Many animals move so fast that there is no time for sensory feedback to correct possible errors. The biomechanics of the limbs participating in such movements appear to be configured to simplify neural control. To test this general principle, we analysed how froghopper insects control the azimuth direction of their rapid jumps, using high speed video of the natural movements and modelling to un...
the effect of gibberellic acid (ga3) and benzyladenine (ba) on aloe vera was evaluated at pot cultivation conditions. this study was performed in two factorial test based on complete random plan and 4 repeats with 12 treatments. the main factor was included spraying, drip and spraying + drip. secondary factor was included concentrations of ga3 and ba at 0, 100, 200 and 400 mg.l-1 levels. the nu...
Auditory spatial acuity was measured in mice using prepulse inhibition (PPI) of the acoustic startle reflex as the indicator response for stimulus detection. The prepulse was a "speaker swap" (SSwap), shifting a noise between two speakers located along the azimuth. Their angular separation, and the spectral composition and sound level of the noise were varied, as was the interstimulus interval ...
Abstract The fracture direction and its intensity are critical properties related to hydrocarbon characterization identification. Both these have an essential role in identifying the of migration, determining sweet spot area, optimizing drilling design. velocity variation with azimuth (VVAz) is a well-known method estimate intensity. This widespread interest because it predicts based on seismic...
ERS – ENVISAT Tandem (EET) data are SAR data pairs acquired by the ERS-2 and ENVISAT ASAR instruments from approximately the same orbits within 28 minutes. During two dedicated campaigns in 2007/2008 and 2008/2009 ESA specifically acquired EET pairs with baselines suited for cross-interferometry (CInSAR). At perpendicular baselines of about 2km the frequency difference and baseline effects on t...
