Spectral and fractal analysis of biosignals and coloured noise
(IEEE, New York, 2007)
The amplitude power spectra and fractal dimensions of surrogate data designed as coloured noise were compared with spectra and FDs of biosignals in order to improve the tools for brain activity analysis. It is interesting ...
Structure and Properties of Barium Bismuth Titanate Prepared by Mechanochemical Synthesis
(11th European Meeting on Ferroelectricity, Bled, Slovenia, 3-7 September 2007, 2007)
Recently there has been renewed interest in the properties
of the Aurivillius phases as temperature-stable ferropiezoelectrics
[1 ]. Several bismuth-layered crystal structures
and their properties have been investigated ...
Analysis of isothermal sintering of zinc-titanate doped with MgO
(Čačak : Technical Faculty, 2007)
The aim of this work was analysis of isothermal sintering of zinc titanate ceramics doped with MgO obtained by mechanical activation. Mixtures of ZnO, Ti02 and MgO (0, 1.25 and 2.5%) were mechanically activated 15 minutes ...
EFFECT OF LANTHANUM ON MICROSTRUCTURE OF BaTiO3: PREPARED BY POLYMERIC PRECURSORS METHOD
(3'd Workshop Nanostructured Materials : Processing and Application September 2, 2007 Bled, Slovenia, 2007)
Due to its high dielectric constant and low loss characteristics, barium titanate has
been used in many applications, such as capacitors, piezoelectric devices, positive
temperature coelficient thermistors, semiconductors ...
