The cutting forces were measured with a piezoelectric force sensor and recorded into data files from which the force components and the resultant cutting forces were extracted.
The data was analyzed and plotted using numerical software.
All data were collected for a workpiece overhang of 40mm.
Even small changes in the processing conditions can result in quite substantial reduction in vibrations.

It was clearly seen that addition of 3MFI PP in 35MFI PP favours the nucleation and the nanocarbon fibres further
The data related to melting endotherms are given in Table 4.
These data show distinctly different mechanism for thermal and thermo-oxidative degradation behaviour of nanocomposite.
At 10% loading, there was further enhancement of induction time to about 115 min. and a reduction in total weight loss to about 4% after 180min.

According to existing data, 22,561 marine species have been identified in China, which represent more than 1/10 of all global marine species [5].
According to existing data, China imported 10 marine fish species, 2 shrimp species, 9 shellfish species, 1 echinoderm species, and 4 algal species for mariculture in 2001; however, during this process, hundreds of alien marine species were inadvertently introduced that present a major threat to local ecosystems.
Displacement of original attached biomes and reduction of species diversity.
For example, the National Basic Scientific and Technological Work Special Plan for “the 12th Five-Year” placed special emphasis on surveying alien invasive species and the damage that they cause, in addition to collecting basic data on the marine environment.

Then the bar was homogenized in air at 320 °C for 10 hours followed by extrusion at 340 °C with a reduction rate of ∼60 %.
In Fig. 1 data on the results of scanning are presented: when the sensor approaches the boundaries of the welded joint, areas with a significant decrease in the insertion voltage are observed.
Fig. 4. includes data on the scanning results: when the probe approaches the boundaries of the welded joint, areas with a significant decrease in the applied voltage are observed.
In view of the fact that similar data were obtained at facility No. 1 (Fig. 4), there are reasons to speak of this as a feature of this type of the welded joint.

This data is outputted using Mathematica.
These may also present patterns within the data associated with the geometry of the implants.
The change in the distribution of load results to an increase in stresses in some regions, while there is a reduction in others.
The study demonstrates an understanding of the knee motion data that shows the stress and strain concentration in the total knee replacement can advance artificial knee design.

Constructing of Simulation Data
The simulation of the job scheduling of hybrid flow-shop is done with 8 jobs to be processed and 6 stages to show the effectiveness of the DE based production cost optimization problem for hybrid flow-shop.
Computational results In order to verify the feasibility and the effectiveness of the DE algorithm to solve the cost optimization problem of hybrid flow-shop, we select 3 sets of scheduling scheme from the simulation data in section 3 to be compared and analyzed.
The completion time And Production Cost of Three Schemes r Scheme1 371 1488.29 217.42 1214.58 2920.29 Scheme2 350 1450.14 203.02 1054.84 2708 Scheme3 354 1467.09 109.73 1054.76 2631.58 According to the analysis of data in table 5, in the pre-set termination conditions, 20 simulations are carried out using DE.
The completion time fmin and the processing costof Scheme 2 are the smallest which means that the processing costshows a close relationship with the completion time of the jobs, and close to the production cost summationsearched by DE algorithm according to the cost, which reflects that the reduction of the completion time can improve the production efficiency.

Thermal conductivity of salt crystals λc is determined by the reference data of physical chemistry or determined by the formulas of A.
For various materials K is accepted in accordance with the experimental data.
The magnitude of the reduction depends on the type of salt, its amount and temperature of the solution.

Plant extracts are used in present work as reducing agent which reduces the rate of reaction and subsequently produce nano-hydroxyapatite particles, although its nature of reduction has not been understood so well.
The X- Ray Diffraction data have confirmed the formation of nano-hydroxyapatite.
Crystallite size is calculated using Scherer’s formula taking the values of X-ray wavelength, 2ϴ and relative Full Width Half Maxima from the X- Ray Diffraction data of the synthesized nano-hydroxyapatite using Plant Leaf Mediated Natural Extracts as natural stabilizers [22].
The SAXS data explains that the increase in concentration of natural stabilizers used decreases the poly dispersity and is independent of the type of natural stabilizers used.

Data are reported in colored maps, indicating the varying hardness
of each zone.
At least 5 specimens of post weld heat treated joint have been tested and data was collected in Table 3.
In the former, as seen only in the first joint, failure occurs far from weld bead in the unaffected material, see Fig. 9.a; in the latter, as can be seen by all other joints, the failure starts at the boundary of weld bead with top of the skin and propagates along the bead boundary until it reaches the maximum thickness reduction of the unaffected material of skin (i.e. corresponding with the maximum depth of bead penetration), then final failure occurs in parent material, as shown in Fig. 9.b, where a certain necking can be appreciated (see arrow in same figure).
In this case all data are collected in Table 4.
