## Abstract This paper extends the results of the two previous papers in several directions. For one we allow slower decay of the coefficients, but higher order differentiability. For this an expansion for the diagonalizing transformations is derived. Secondly unbounded coefficients are permitted.
## Abstract We study the spectral theory of differential operators of the form on β^2^~__w__~ (0, β). By means of asymptotic integration, estimates for the eigenfunctions and__M__ βmatrix are derived. Since the __M__ βfunction is the Stieltjes transform of the spectral measure, spectral properties
A single derived index of the power spectrum of the diaphragm electromyogram (EMG) has been used in detecting fatigue. Additional information in the EMG could be used to study diaphragm function in other respiratory conditions. Diaphragm EMGs and calculated power spectra at 12 frequencies were measu
