OBJECTIVE This prospective study was conducted to evaluate the value of sonographic B-lines (previously called "comet tail artifacts"), which are long, vertical, well-defined, hyperechoic, dynamic lines originating from the pleural line in assessment of interstitial lung diseases (ILD) and compare them with the findings of chest high-resolution computed(More)
—Subspace methods such as MUSIC, Minimum Norm, and ESPRIT have gained considerable attention due to their superior performance in sinusoidal and direction-of-arrival (DOA) estimation, but they are also known to be of high computational cost. In this paper, new fast algorithms for approximating signal and noise subspaces and that do not require exact(More)
BACKGROUND Morbid obesity magnifies the importance of the fat-blood solubility coefficient of the anesthetic in its relation to emergence and recovery. Using bispectral index (BIS) monitoring for the titration of the administration of inhaled anesthetics such as desflurane may permit a less consumption and more rapid recovery from desflurane anesthesia in(More)
Many modern high-resolution spectral estimators in signal processing and control make use of the subspace information afforded by the singular value decomposition of the data matrix , or the eigenvalue decomposition of the covariance matrix. The derivation of these estimators involves some form of matrix decomposition. In this paper, new computational(More)
