Blind deconvolution of ultrasonic traces accounting for pulse variance

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 1999
The ability of pulse-echo measurements to resolve closely spaced reflectors is limited by the duration of the ultrasonic pulse. Resolution can be improved by deconvolution, but this often fails because frequency selective attenuation introduces unknown changes in the pulse shape.

Journal of Applied Psychology, 2001
Cross-sectional studies of attitude-behavior relationships are vulnerable to the inflation of correlations by common method variance (CMV). Here, a model is presented that allows partial correlation analysis to adjust the observed correlations for CMV contamination and determine if conclusions about the statistical and practical significance of a ...

Structured Accounting of the Variance of Demographic Change

The Journal of Animal Ecology, 1993
A method is presented of producing a multi-way analysis or account of the variance of the relative change in density from one year to the next of a wild population which is structured in some way (e.g. by age group). The method is dependent on accounting identities in which the relative change in size of the whole population is expressed as a sum over ...

Accounting for variance heterogeneity in French dairy cattle genetic evaluation

Livestock Production Science, 1999
Abstract A linear mixed model assuming heterogeneous residual variances and known constant variance ratios was applied to the analysis of milk, fat, and protein yields, and fat and protein contents in the French Holstein, Montbeliarde, and Normande dairy cattle populations. The method was based on a log-linear model for residual variances.
