A novel chaotic system is explored in which all terms are quadratic except for a linear function. The slope of the linear function rescales the amplitude and frequency of the variables linearly while its zero intercept allows offset boosting for one of the variables. Therefore, a free-controlled chaotic oscillation can be obtained with any desired amplitude, frequency, and offset by an easy mod...

Two offset IRAs are numerically modeled and analyzed. The reflector of the offset IRA is an offset portion of a paraboloid that is carved out by the intersection of the paraboloid and a cone whose apex is at the focal point of the paraboloid. A pair of conical curved plates is placed on the surface of the cone as TEM feed arms. The TEM feed arm of the first IRA is conical throughout its length ...

Reflection amplitude as a function of offset is effective in characterizing lithology in oil producing basins. Experience shows that AVO inversion methods based on amplitude-preserved prestack migration typically provides a more accurate lithology estimation than NMO-based AVO analysis. However, some artifacts may be introduced into the migration section, which can obscure the estimate of reser...

A compacted and low-offset low-power CMOS amplifier for biosensor application is presented in this paper. It includes a low offset Op-Amp and a high precision current reference. With a novel continuoustime DC offset rejection scheme, the IC achieves lower offset voltage and lower power consumption compared to previous designs. This configuration rejects large DC offset and drift that exist at t...

Regularization and interpolation of 3D offset classes prior to imaging are an important challenging step in the marine seismic data processing flow. Here we describe how perform this task using a deep neural network, explain overcome challenge creating suitable training set. The set is generated by de-migrating stacked pre-stack depth migration images. For each class volume, de-migrate migrated...

As complementary to Synthetic Aperture Radar (SAR) Differential Interferometry (DInSAR), SAR Offset Tracking (OT) is an efficient tool for large ground deformation monitoring in situations when DInSAR cannot work. However, images are affected by speckle noise and some strong point-like scatters which can cause what known as Patch Like (PL), a kind of errors that be seen homogeneous patches almo...

Abstract The application of quantitative interpretation techniques for hydrocarbon prospect evaluation from seismic has become so vital. effective employment these is dependent on several factors: the quality and well data, sparseness physics rock, lithological structural complexity field. This study adopts reflection pattern, amplitude versus offset (AVO), Biot–Gassmann fluid substitution cros...
