Extension of a classic theory of the low frequency dielectric dispersion of colloidal suspensions to the high frequency domain
(American Chemical Society, 2010-10)
The classic Shilov-Dukhin theory of the low frequency dielectric dispersion of colloidal suspensions in binary electrolyte solutions [Shilov, V. N.; Dukhin, S. S., Colloid J. 1970, 32, 245.; Dukhin, S. S.; Shilov, V. N. ...
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, ...

Time-frequency analysis combining wavelets and the envelope technique for fault identification in rotary machines
(2013-03-18)
Nowadays the method based on demodulation by envelope finds wide application in industry as a technique for evaluation of bearings and other components in rotating machinery. In recent years the application of Wavelets for ...
A Simple maxwell Based Model in Order to Represent the frequency-dependent viscosity measured by ultrasound
(2008-12-01)
A previous work showed that viscosity values measured high frequency by ultrasound agreed with the values at low frequency by the rotational viscometer when conditions are met, such as relatively low frequency viscosity. ...
