An effective wavelet method to detect and mitigate low-frequency multipath effects
(2008-12-01)
To ensure high accuracy results from GPS relative positioning, the multipath effects have to be mitigated. Although the careful selection of antenna site and the use of especial antennas and receivers can minimize multipath, ...

Optimal Frequency Range Selection for PZT Transducers in Impedance-Based SHM Systems
(Institute of Electrical and Electronics Engineers (IEEE), 2010-08-01)
Piezoelectric transducers of PZT (lead zirconate titanate) have been widely used in structural health monitoring (SHM) systems based on the electromechanical (E/M) impedance technique. In this technique, damages in the ...

Auditory nerve frequency tuning measured with forward-masked compound action potentials
(2012)
Frequency selectivity is a fundamental cochlear property. Recent studies using otoacoustic emissions and psychophysical forward masking suggest that frequency selectivity is sharper in human than in common laboratory ...
Environment-dependent regime of longevity selection in the chromosomally polymorphic species Leptysma argentina (Acrididae: Orthoptera)
(University Florence Botany Institute, 2012-09)
In previous papers it was reported that a Robertsonian translocation (centric fusion) affected external phenotype in the grasshopper Leptysma argentina and that thorax height was the target of adult viability selection. ...
