It has been found that the additions of Cu and Zr cause the reduction of the difference of grain size between the hard magnetic phase and the soft magnetic phase, that increase the exchange coupling between them.
The reduction of △Tx would repress the growth of the Fe3B grain which has been crystallization first.
For illustration, the data are also plotted and displayed in Fig 2.

The samples were compressed to a reduction of 50% at two temperatures (623 and 673K) with different strain rates (0.01, 0.1 and 1s-1).
All the specimens were compressed to about 50% reduction.
The experiment data were recorded by the microprocessor system of the Gleeble-1500D.

Reduction of strength due to exposure to 400 and 800 °C is also evaluated and in case of 400 °C temperature exposure the results are very promising.
Reviewed literature focused on chopped basalt fibre reinforced concrete [3, 4] gives promising results, but data are not compact therefore further investigation is required.

Due to the large amount of data produced in this simulation, velocity magnitude contours are shown for selected parts of the flow domain.
Data Reduction.
Accord to the analysis of Data Reduction , the exposure time of maxima stress for the CFD model is effective, which may bring the particle damaged.
By performing a reduction to simple loading functions and separating the damaged parts of the loading functions from the nondamaged, the ratio trauma of blood cells can be estimated from the amount of cells damaged due to the lysis of cells at the wall according to the threshold shear stress.

It must be noted that the technical evolution towards higher Laser power has been followed with a continuous components and package size reduction, creating significant challenges to the Laser cooling engineers.
While the technical benefits related to the integration of fewer components are intuitive to promote the environmental performance of the FL technology, data on the energy savings benefits are still on the hands of few manufacturers, and only some parallel estimation has been recently available.[6] Moreover, besides the Laser and cooling units, other important electrically fed sub-systems, such as the general control unit (including the motorized head positioning) and the exhaustion system, should be considered on the analysis of the energy demand of a Laser cutter.
This work brings out complete data on the electrical energy demand of CO2- and FL-based equipments, right from the application field, essential for a reliable and accurate technology comparison, providing the proper support for the specification of an improved machine.
The power measurement equipment and conditions used, as well as the theoretical background applied in the power and energy data treatment is explained in a previous work [8].
This would result on a significant reduction on the power demand of the chiller and on its improved efficiency.

This empirical fit allows models to be constructed that relate damage parameters of interest (such as stiffness reduction and its location) to measurable output features (e.g. natural frequencies).
It could be a traditional reduced order model (as obtained from Guyan reduction or Craig-Bampton methods), a neural network, or a statistically derived model.
Metamodels may then be fit to these intelligently chosen data points using standard multiple regression methods resulting in a polynomial model that relates input parameters to output features.
Higher error was expected at the stiffnesses (3000, 5000) and locations (2, 4) that were not included in the training data set and this was observed.
Forward relationships may be generated with relatively few "training" data sets and the inverse formulation may then be applied to conduct damage identification with some quantifiable degree of accuracy.

The standard of vehicle gasoline formulated by the National Environmental Protection Agency, it required the olefin content should not be exceed 25%, this higher than the European standard(not exceed 18%), However, due to the structure of petroleum products is unreasonable, the olefin content did not meet the standard in the majority of China’s refineries, Therefore, it is necessary to develop olefin reduction technology.
Some common gasoline olefin reduction technology included: Selective hydrogenation, Development catalyst and additives of olefin reduction, Back refining technology, Aromatization, Etherification,etc[1].
It shows that the characteristic peaks of γ-Al2O3 and Hβ are observed in all catalyst and their XRD data compared similar to each other, this indicate that the hydrothermal modification does not change crystalline structure of catalysts, they have good thermal stability.
NH3-TPD data graph for these modified catalysts is shown in Fig.4.
The Fig.6 shows that the characteristic peaks of γ-Al2O3 and Hβ in all catalysts and their XRD data similar to each other, this proved once again that the hydrothermal modification does not change crystalline structure of the modified catalysts and these catalysts have good thermal stability.

To manufacture lighterweight vehicles, substantial reductions could be achieved by employing ultra-lightweight magnesium (Mg) alloys [2,3].
Despite the potential of substantial reductions in weight, most wrought Mg alloys exhibited a high degree of anisotropy and tension-compression yield asymmetry [4-7].
The fatigue life (i.e., the number of cycles to failure, Nf) as a function of the applied total strain amplitudes (Δεt/2) of the extruded GW103K alloy is plotted in Fig. 5(a), along with the experimental data reported in the literature for various extruded Mg alloys [6,7,15] for comparison.
Run-out data points were indicated by arrows pointing horizontally at or more than 107 cycles.

The high dimensionality of vibration response data does, however, pose a problem for such techniques.
In total data was recorded for 6 states of the structure: the 10gram mass being positioned at each of the location M1-M6.
The technique described was applied to a small subset of the data gathered from the wingbox experiment.
Fig. 3: A small section of the data recorded for the wingbox experiment.
The greedy feature grabbing procedure was applied to the data depicted in Fig. 3.
