متن کاملAmplitude balanced PEF estimation
Inverse theory teaches us that the residual, or misfit function, should be weighted by the inverse covariance matrix of the noise. Because the covariance operator is often difficult to estimate, we can approximate it with a diagonal weight that can be more easily computed. This paper investigates the possible choices of weighting functions for the data residual when prediction-error filters are...
متن کاملPeak expiratory flow (PEF) monitoring.
T he Wright peak expiratory flow meter was introduced in 1959 and provided a portable piece of equipment for assessing some aspects of lung function in the ambulatory care setting. The original device has been supplanted by the mini Wright peak flow meter (and a range of other devices) which have become relatively cheap but are reasonably reliable for home monitoring. So, with an available devi...
متن کاملSpitz makes a better assumption for the signal PEF
In real-world extraction of signal from data we are not given the needed signal prediction-error filter (PEF). Claerbout has taken S, the PEF of the signal, to be that of the data, S ≈ D. Spitz takes it to be S ≈ D/N . Where noises are highly predictable in time or space, Spitz gets significantly better results. Theoretically, a reason is that the essential character of a PEF is contained where...
متن کاملpEF-BOS, a powerful mammalian expression vector.
Polypeptide chain elongation factor l a (EF-la) is an eukaryotic counterpart of E. coli EF-Tu which promotes the GTP-dependent binding of an aminoacyl-tRNA to ribosomes. EF-la is one of the most abundant proteins in eukaryotic cells, and expressed in almost all kinds of mammalian cells. Recently, we have isolated human chromosomal gene coding for EF-la, and shown that the promoter of EF-la chro...
