On the possibility of breaking the heterodyne detection quantum noise limit with cross-correlation
(Institute of Electrical and Electronics Engineers Inc., 2018)
The cross-correlation sensitivity of two identical balanced photodiode heterodyne receivers
is characterized. Both the balanced photodiodes receive the same weak signal split up equally, a situation
equivalent to an ...
Modelos de volatilidade estatística
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Estatística - PPGEs, 2008-08-22)
In the financial market usually notices are taken of the shares
sequentially over the time in order to characterize them a time
series. However, the major interest is to forecast the behavior of these shares. Motivated by ...
Adoption of lean thinking practices at Brazilian auto part companies
(2012)
The objective of this study is to analyze the adoption of lean thinking practices at Brazilian auto part companies. For such, a survey was conducted at 75 sector companies. The results reveal that among all practices, the ...
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 ...

Residual signal auto-correlation to evaluate speech in Parkinson's disease patients
(Associação Arquivos de Neuro- Psiquiatria, 2006-12-01)
Objective: To evaluate the maximum residual signal auto-correlation also known as pitch amplitude (PA) values in patients with Parkinson's disease (PD) patients. Method. The signals of 21 Parkinson's patients were compared ...
