Noise reduction is, for several purposes, a very challenging and complicated issue.
For analyzing ECG signals, data 100m, 104m, 105m, 119m, and 208m collect from the Physionet site under the MIT-BIH arrhythmia database.
Step 1: Read ECG signal xn from MITBIH data base and add noise vn to that signal to get a noisy ecg signal yn=xn+vn                                                                                                         (6) Step 2: Apply EMD [10] to the noisy ECG signal yn then the decomposition is as follows EMDyn=pn=k=1Nckn+rNn                                       (7) Where pn is the decomposed signal, rNn is the Nth residue and cknis the kthorder Intrinsic Mode Functions (IMFs).

Recent data (2016) at European level estimate that approximately 18 million jobs are directly created by the construction industry, in Europe [1].
According to last decade data, worldwide, there are four dominant Garnet producing countries: India (700 000 metric tonnes), China (470 000 metric tonnes), Australia (150 000 metric tonnes), and the United States (54 000 metric tonnes) [16, 19].
In case of Garnet waste gradual replacement of fine sand in the concrete mix, a reduction of Zn content under the accepted 5 ppm was recorded, demonstrating the capacity of cement-based material to confine the Zinc content in the matrix [28], confirming previous studies in the field [38].

There is a critical need of a robust design approach which is greatly able to simplify the number of experiments required to obtain the necessary data.  
For ease of comprehension, the data of individual S/N ratio are also depicted graphically in Figs. 3.

This measurement was then compared with the data provided by the JCPDS card no. 03-0931, which corroborated the findings reported in references [46, 47].
This measurement agreed with the data provided by the JCPDS card no. 01-1174, and was also compatible with prior findings [49].

Artiomas [17] analyzed 1303 samples of CFST experimental data.
Resistance of members to axial compression must be verified [18]: (3) χ : reduction factor due to the composite column buckling according to the European curves a, b, c. 2.2.
The mechanic-reliability coupling requires data concerning the reliability model (random variables, distribution laws, coefficient of variation) and the parameters of the reliability resolution algorithm on the one part, and the numerical model for calculating the performance function on the other part.
According to Fig.4 and Fig.5, the results of numerical simulation show a good concordance with experimental data.

A reduction in chemical efficiency is observed by increasing the input thermal power (i.e. the total mass flow rate) at fixed equivalence ratio due to the shorter gas residence time.
Thus this condition has been numerically reproduced in order to cross check the experimental and numeric data, to tune the CFD software, and to understand whether it is an available tool to simulate that kind of devices.
The specific heats Cpi are fitted by polynomials of temperature from the GRIMech Thermo Data file [36], while gas kinetic theory [37] predicts transport properties, µ and k.

Literature data added to Figure 2b are in good agreement with the measured trend of the tensile properties.
Literature data added to Figure 2c are less consistent with the measured trend of the strains.
This makes a direct comparison with literature data difficult.
Only Liu et al. [41] referenced the HE index to the reduction in fracture area RA instead of the fracture strain Al.
Literature data were added to Figure 4a and 4b.

The recorded load elongation data were analyzed first to obtain the tensile stress strain plots followed by estimation of yield strength (YS), ultimate tensile strength (UTS), % total elongation (%EL), % reduction in area (%RA) strain hardening exponent (n) and strain rate sensitivity (β).
The strain hardening exponent was computed from the stress strain data following ASTM standard E 646-93 using the Holloman relation σ = Kεn.
The volume fractions of the different constituent phases were estimated from the XRD data of the entire spectrum using Rietveldt analysis software; the amounts of martensite are found to be 34% (monotonic), 25% (cyclic, R= -0.5), 12% (cyclic, R= -0.8) and 17% (cyclic, R= -1.0);the presence of e martensite could be detected only in two specimens with amounts 5% (cyclic, R= -0.5) and 4% (cyclic, R= -0.8).
Tests were conducted on a 100 kN closed loop servo-hydraulic testing machine interfaced to computers for automatic test control and data acquisition.
