When spatially dense mobility shapes are measured with scanning laser Doppler vibrometers. it is often impractical to use phase-separation modal parameter estimation methods due to the excessive number of highly coupled modes and to the prohibitive computational cost of processing huge amounts of data. To deal with this problem. a data compression method using Chebychev polynomial app... https://www.ashleyshomestores.shop/product-category/wide-seat-recliner-with-power/
