Experimental data.
Since the four available data groups with two levels of two parameters plus amplitude stress levels do not allow for a full quadratic model, the untreated group data were included with appropriate parameters [t = 0 h / T = 293 K].
Data fitting is very accurate, resulting in narrow confidence intervals (about ±4%) for the estimated parameters.
In particular, this approach allows to optimize the treatment on the basis of a proper model for data representation by choosing the most appropriate distribution for fatigue data and its parameter expression.
Moreover, potential treatment influence on data dispersion can be taken into account.

Using data from tests on laboratory studies, comparisons are made of the properties and performance of the gangue, fly ash and silica fume concrete with conventional Portland cement concrete of similar and same mixture proportions.
Reduction ratio of concrete with mix supplementary cementing materials such as gangue, fly ash, slag, silica fume and admixtures is given Fig. 2.
Water reduction of difference between W/GFSSA and mixtures Fig. 2.
The addition of fly ash 15%, gangue 15% and slag 10% resulted in a reduction in compressive strength.
The reduction in strength is attributed to the fact that specimens were cured for a short period of time.

The simulation results are compared with the experimental data obtained through pilot scale downdraft gasifier.
Their predictions were in good agreement with published experimental data.
Table 2 shows the comparison of results between the predicted results and experimental data at gasifying agent temperature 900°C.
This was validated using experimental data from pilot scale downdraft gasifier.
The model is capable of predicting gasifier performance under various operating conditions and the predicted results agree well with the experimental data.

Each queue object has a built-in set of data statsSize, which collects statistics regarding the use of this object.
The function mean () returns the average of all the measured values of data set.
Next it is necessary to add items to the statistics based on which the solver AnyLogic will provide us with the necessary data.
For this we use data element of block diagram to display our objective function and constraints directly.
Further, from the same palette we will insert three elements of bar charts and prescribe the data elements, chart data in the data columns, i.e. time_obrabotki.

So, the use of a naturally derived compound with an anticancer effect such as curcumin (Cur) could be an opportunity for an enhanced cytotoxic effect with the reduction of adverse effects.
The data obtained was used for the analysis of IC50 and further synergism study.
The program investigates the drug concentration and dose-effect on the cell viability which are determined as the combination index (CI) and dose-reduction index (DRI).
Data were reported as mean ± standard deviation.
Finally, the CDDP/Cur loaded PCL-NPs have proven the synergism and dose reduction effect by presenting a very close IC50 (12.58 μg/mL) to the constant ratio synergism study (13.11 μg/mL).

In order to use the available experimental data [26] for the model specification and calibration, we treat the calibration as a two-stage process.
The concept of essential () and non-essential () specific works of rupture (Fig. 1), and corresponding experimental data [26] will be used for the specification of the model.
Fig. 3 depicts the model response with unloading paths showing the damage effects on stiffness reduction.
Given the dependence of parameters governing the post-peak response on width of the fracture process zone, and its implicit link with the length scale , a practical approach is developed here for the determination of from a given value of and the experimental data provided in [26].
However for post-peak response, due to the scattered experimental data, different values of corresponding to different specimen thicknesses was reported and used: (1mm thickness), (3mm thickness), and (an intermediate value).

Abstract: This paper presents the results of an outdoor investigation of wind-drifted snow
distribution around a cube.
The inlet profiles of the simulation adopted data got from wind tunnel.
Due to the complexity of the special material, only few researchers get the data from field investigation though lots of job carried out in simulating.
Scan valve and DSM3000 are adopted as data collection dealt with program.

Although this practice may cause some reduction in tensile properties, it has been shown that
significant improvements may be achieved in creep resistance, fatigue strength and fracture
toughness.
Stress-/umber of Cycles (S-/) data for the Al-Cu-Mg-Ag-Mn-Zr alloy tested in the (a) T6 and (b) UA conditions [4].
Although such a treatment inevitably results in some reduction in tensile properties when compared with those for the fully hardened T6 temper, creep and fatigue resistance may both be enhanced.

The oxidation-reduction potential (ORP) value and storing time of SOPSF were explored in comparison with those of poly-Si-Fe (PSF).
This work will provide some useful data for further development of this kind of coagulant.
Just as stated in Preparation of SOPSF, dilution of SOPSF or PSF at Fe concentration of 0.18 mol.L-1 was often used as storage product, therefore, a proper reduction of temperature was very useful to improve SOPSF stability.
