Pitch detection algorithms based on zero-cross rate and autocorrelation function for musical notes
(2008-09-22)
This paper discusses two pitch detection algorithms (PDA) for simple audio signals which are based on zero-cross rate (ZCR) and autocorrelation function (ACF). As it is well known, pitch detection methods based on ZCR and ...
Long-range dihadron correlations in high multiplicity pp and PbPb with CMS
(2011-01-01)
Charged dihadron angular correlations measured using the CMS detector at the LHC for both pp collisions at 7 TeV and PbPb collisions at 2.76 TeV are presented. New results on the ridge correlation structure in high ...
Changing of the spontaneous polarization in niobate nanoparticles induced by non isovalent doping
(2015-01-01)
Ferroelectric niobates with tetragonal tungsten bronze TTB-type structure have shown great technology interest for application in pyroelectric detectors and piezoelectric transducers, sensor/filter in composite. The synthesis ...
Natural radionuclides distribution in the shelf and upper slope off southeast Brazil
(Associação Brasileira de Energia NuclearRio de Janeiro, 2009-09-27)
In recent decades, Oceanography has been using a variety of radionuclides as tracers to understand the ocean
dynamic processes, handling and disposal of sediments of seabed. In this context, the determination of ...
First principles calculations for vacancies and antisites in PbSe and PbTe: bulk and nanowire.
(Sociedade Brasileira de FísicaÁguas de Lindóia, 2013-05-13)
The energetic stability and the electronic properties of vacancies (VX) and antisites (XY) in PbSe and PbTe are investigated. PbSe and PbTe are narrow band gap semiconductors and have the potential to be used in infrared ...
