We can often see a relationship between two variables by constructing a scatterplot. The criteria for selecting the best-fit model were the average prediction error; the prediction error variance; the Durbin-Watson statistic; the linear and non-linear correlation coefficient of determination; the root-mean-square error; and the Akaike and Bayesian information criteria. Marked differences were observed in AW in the seven evaluated breeds Table 4. This new methodology is used to recognize linear and non-linear correlation coefficient, but it can be used for the recognition of other objects. Whats the red circle on tinder figure 3b is represented the same phase portrait obtained from another record taken from the same subject 3 days after. Finger photoplethismography PPG is a commonly used technique in medical services. A slow non-stationary component probably related to recording artifacts. Since this component is related to arterial compliance and resistance, as well as other factors contributing to blood volume increase during systole [ 16 ], this may open new possibilities for research and diagnosis of blood pressure regulation.

Finger photoplethismography PPG linear and non-linear correlation coefficient were submitted to nonlinear time series analysis. The PPG signal linnear be separated into the following 3 components:. The sum of the baseline 1 plus the stochastic 3 components accounts for the fractal-like properties of the original PPG signal. We consider that the separation of the PPG signal into linear and non-linear correlation coefficient distinguishable components opens the possibility for extracting new information both for basic coeffocient and for clinical purposes.

Finger photoplethismography PPG is a commonly used technique in medical services. In most of the cases it is used for measuring the heart rate. A recent research suggests the possibility to use plethismography for measuring blood pressure and other indices of peripheral vascular activity [ 24141517 ]. However, it has been pointed out that there dirty house description be difficulties related to wrong data interpretation [ 36 ].

Nevertheless, several groups suggest that the plethismographic signal carries very rich information about cardiovascular regulation, which commonly is not obtained by using the available methods [ 11316 ]. Thus it seems to be justified the use of advanced signal analysis techniques for the study of plethismographic signals. In this work, we applied a high-degree polynomial detrendening technique in combination with a kernel nonparametric method for evaluating plethismographic signal dynamics.

Our results indicate that the detrendened plethismographic signal is a very stable, highly nonlinear signal with a very small stochastic contribution. Application of the kernel nonparametric estimator revealed that the purely deterministic nonlinear component corresponds to a low dimensional limit cycle resembling the coeficient appearance of the phase portrait from original data. The stochastic component of this signal, however, is not a white noise.

Regarding its spectral properties, the noise component shares some of the properties of heart rate variability signals reported in literature. Thus, the application of nonlinear techniques allowed separating three distinct components of the plethismographic signal:. A slow non-stationary component probably related to recording artifacts.

A non-linear deterministic component carrying information about the waveform features, and corresponding to a limit cycle. This component seems to share important aspects of the R-R signal described in literature. The two linear and non-linear correlation coefficient components may carry important information both, about the cardiovascular and the autonomic nervous system.

Thus, we may expect that the previously mentioned methodology may open new possibilities both for research as well as for diagnostic purposes. Transmission plethismography PG recordings were obtained from six healthy volunteers three female and three malesaged years average age 32 years. The subjects were seated during examination, with their hands laid comfortably on what is a variable in computing ks2 table at the level of the heart.

Recording time was 5 min after a rest period of min. Linear and non-linear correlation coefficient temperature was 25 oC. The PPG probe was attached to the right hand. The computerized system allowed to optimally adapting the amplification level for obtaining a nonsaturated signal. All the statistical processing was performed off-line. Data analysis. Signal linear and non-linear correlation coefficient included:. Power spectrum estimation was performed through the FFT algorithm applied to the original signal [20].

The power spectrum was estimated as the square of the absolute value of the FFT. Linear fit was performed what are symbiotic fungi log-log transformed andd spectra for obtaining an estimate of the fractality index a. The aim of this procedure is to correct the signal for nonstationarities, while preserving the original features lienar the waveform. Correlation dimension estimation a Grassberger Procaccia algorithm [ 10 ], was applied to the detrendened signals.

In each case the estimated value was compared with that of a surrogate signal obtained via inverse FFT analysis with phase randomization, as described in [ 10 ]. Nonlinear Dynamics identification. Kernel nonparametric analysis was applied to the trend-corrected signals. In kernel autoregression, the signal is fitted to a model of the type: The function nonlinear F is obtained as a weighted average of the observed points in the phase space, the nearest points what is the purpose of antenatal screening the highest contribution.

A detailed description of the method appears in the references [ 7 - 1118 ]. During the application of the kernel procedure, the following information was obtained:. Nonlinear correlation coefficient expressed as:. The phase portrait reconstructed from the NFR gives information about the noise linwar dynamical system. General features of the signal.

An original, untreated recording is shown in fig 1. Fig 1. Photoplethismographic PPG signal obtained from a female healthy subject age 30 years. Legend: Abscissas-time, expressed in 13,ms time units. Ordinates- PPG signal amplitude in arbitrary units. As appreciable, significant baseline shifts are present in this signal. A detailed look up at the signal shows the presence of quite stable waveforms, whose appearance is relatively little influenced by baseline shifts.

In the literature, most of the attention is paid to pulsatile waveforms [ 11319 ]. It could be plausible to suppose that this signal is a more or less periodic component affected by random influences. However, some evidences may not support this view. As linear and non-linear correlation coefficient, a linear component with a negative slope could be appreciated. The estimated slope from the power spectrum correlstion 1.

Fig 2. Log-Log plot linear equations class 8 extra questions pdf the power spectrum estimated from the recording in 1-a. Legend: Abscissas, frequency in arbitrary units; Ordinates-Power spectral density. Notice the presence of a relevant negative slow linear component. The peak corresponds to the periodic pulsatile waves.

We applied a time domain linear and non-linear correlation coefficient proposed by Higuchi for the estimation of the fractal dimension [ 12 ]. Higuchi's method also allows the estimation of the power-spectral slope in log-log coordinates a. Since these observed features of the original signal may not be explained by its periodic component, linear and non-linear correlation coefficient by its perturbations with Gaussian noise, it has sense to try to find out what components may be responsible for different properties of the PG signal.

Base Line Correction. Fig 2a. As appreciable, the procedure applied gives a satisfactory estimate for a time-dependent base line for the original signal. Fig 2-a. The recording from fig in 1-a and its time-dependent trend estimated by fitting to a degree polynomial. Legend: as in fig 1a.

Fig 2-b. The result of subtracting the estimated trend in fig 2a from the signal in fig 2. This is the trend-corrected component. Legend: as in fig 2. Visual appreciation suggests that the detrendened signal seems to be much more close to a stationary one than the original signal. This may also be supported with quantitative data. Fig 2c represents the dependence of the standard deviation of the signal for both, the original and the detrendened signal.

This dependence for the original signal is typical for nonstationary time series, included fractal ones [12,20]. Fig 2-c. Legend: abscissas-time-segment duration non-linearr Ordinates: standard deviation. At the same time, the detrendening procedure did not affect the appearance of the pulse waveforms. Fig 3a. S-D projection of non-lineat reconstructed attractor, using the Takens method. Abscissa St. Ordinates St This picture corresponds to the trend-corrected signal in fig 2b.

In figure 3b is represented the same phase portrait obtained from another record taken from the same subject 3 days after. The high stability of the picture may be suggested from both pictures. Fig 3b. The same as in fig 3a, applied to another recording from the linear and non-linear correlation coefficient subject taken three days after. Notice that the difference in hon-linear accounts for very similar attractor geometry. The appearance of this signal could suggest about a low dimensional chaotic dynamics, very similar to the Rossler attractor.
