A new roller assembly for use in heavy duty applications such as hooklift trucks and conveyors in mining operations is based on a nonmetallic roller having high tensile strength around 12000 psi, high compressive strength in the neighborhood of 15000 psi, a modulus of elasticity about 400 ksi, and operating temperature range of about \u221230F to 200F. The method includes receiving the seismic data acquired at one or more receivers due to one or more marine vibroseis sources that emit one or more vibroseis sweeps. The fiber assembly plate receives the at least one optical fiber. The channel tap weight is programmed into an equalizer that uses the model to estimate unknown data symbols in the received data.
