We have developed nonlinear beamforming (NLBF), a method for enhancing modern 3D
prestack seismic data acquired onshore with small field arrays or single sensors in which weak …

Modern land seismic data acquisition is moving from sparse grids of large source/receiver
arrays to denser grids of smaller arrays or point-source, point-receiver systems. Large arrays …

We apply supergrouping of land data after moveout corrections and prove that it can address
noise issues caused by extreme near-surface scattering present in a desert environment. …

Estimating converted-wave (S-wave) statics is a difficult challenge in reality, but it is crucial
for the final success of PS-wave processing and imaging. A novel and practical method is …

Newton's rings are an interference pattern related to fringes of equal thickness. This image
can be obtained on a simple experimental optical setup. Modern common renderers, based …

In a tectonically complex area of northwest Pakistan, MOL Pakistan and its partners acquired
two 3D seismic surveys. Extreme topography led to irregular shooting geometry. Varied …

Maurice Merleau-Ponty enjoys a special place among contemporary French bourgeois
philosophers and aestheticians. Statements by Sartre, Camus, Hyppolite, Dufrenne, Ricoeur, …

While the mathematical modeling of optical phenomena, a computer calculation is often
performed, confirming the conclusions made. To do this, a virtual computer model of the optical …

This paper describes a new 256-bit block symmetric substitutionpermutation cipher, called
managed substitution cipher. This is a cipher with single-layer permutated transformations in …
