Torsion tests provided directly the torque versus number of turn curves.
The number of turn to failure was used as a measure of ductility of the P92-2%W steel.
The number of turns increases with increasing temperatures reaching a maximum at about 1150ºC.
At higher temperatures deformation takes place in the α + γ two-phase field and precipitation of ferrite at the austenitic grain boundaries occurs.
Number of turns to failure in the torsion test as a function of temperature.

The Wms values computed for a number of raw compositions agree with the experimental data.
The number of particles involved in the process of gelation, and the number of particle aggregates will reach their maximum values.
The number of fine particles concentrated on the surface of large particles will reach its maximum value at that moment.

A number of studies use the execution time as an indicator while measuring the performance, which is defined as follows [1]:
(1)
where PFloss is the performance loss, fmax is the maximum frequency, and fn is a frequency lower than fmax.
The second part is about the time spent in external memory accesses, which are determined by the number of cache misses and are closely related to the behavior of the running program.
We use the number of instructions executed and the number of cache misses in Performance Monitor Unit (PMU) as CPU operations and memory accesses respectively.

The original purpose was to sparse representation below the Shannon sampling frequency representation and compressed signal, the thing in the de-noising, wavelet transform peace at constant wavelet also developed a number of efficient algorithms; sparse representation has been successfully applied to the image dynamic range compression, separation images of cartoons and the like texture component.
Additive noise and signal nothing to do with the signal superimposed, such as general electronic noise linear amplifier; whereas multiplicative noise modulation signal, such as quantum noise, film grain noise and other affected; and divided by a common source of noise, the noise can be divided into electronic noise, optical noise, noise component materials.
For instance, not all blocks are able to find their similar blocks, when a small number of similar blocks or impossible to find a similar block, de-noising effect is not ideal; Furthermore, the current non-local block matching methods are used to find similar blocks, when noise is serious, the way to find a similar block may not be similar, thus affecting the de-noising performance.
For example, sparse model for a single image or a block, the image processing based on the model are often sparse independently for each image block, such correlation is ignored between the image blocks, similar blocks because sparse decomposition potential difference greater instability estimates obtained cause significant artifacts in the reconstructed image appears; Furthermore, the size of the class library atoms method is generally determined in advance, this is not an ideal situation, because of the different image, the number of atoms required for the expression should not be the same; addition, and a final study the atomic database such sparse coding methods, particularly the former, generally a large amount of computation required, this method will limit the redundant sparse practical application.

Accordingly separation and purification of fine grained refractory ore are becoming an urgent issue in field of the mineral processing industry.
If the detected magnetite sample is set in cavity of L2 such as real-time testing in the process of sales, perhaps if the detected material sample on a conveyor belt is traveling through the cavity of L2 such as on-line monitoring in the processing process, the core magnetic flux and magnetic permeability would be increased, thus Uo would be also increased, according to Faraday's law of electromagnetic induction [4], its valid value is (4) In Eq. 4, f is frequency of alternating magnetic flux, N is number of turns of the secondary coil L2 and L3, is the maximum number of alternating magnetic flux.
According to Eq. 7, if number of turns of the finite length inductor winding with cylindrical magnetite iron core is N, cross-sectional area perpendicular to the axial direction is S, relative magnetic permeability of magnetite is μr, and air relative permeability is taken 1, so radial micro component of magnetic induction intensity of arbitrary spatial point P is the following
Thus, designing scope of prepared samples is from 20.00% to 65.30%, number of the measuring samples is 20.

Introduction
Important parameters of the injection molds are the surface quality of parts produced, durability (the number of cycles that mold can withstand), and performance [1].
This opens up the possibility of fitting the properties of parts to those required in these specific conditions and reducing the total number of parts in the nodes.
The predominant number of particles has a shape close to spherical.
The surface of most particles is not smooth, but is covered with a large number of small particles.
This leads to the formation of grains elongated in the z-direction.

The appearance of the ore dump and the profile numbers are shown in Fig. 1.
Appearance of the ore dump and profile numbers.
For the enrichment of ore with a grain size of more than 6 mm, we initially suggest using dry magnetic separation.
Products cast from the resulting cast iron when replacing up to 30 % of scrap metal with metallized ore-coal pellets met all the requirements, the number of defects did not differ from cast products obtained earlier using cast iron smelted on a conventional charge.
The use of metallized pellets allows us to implement a number of technological aspects for the stable production of high-strength cast iron with spherical graphite, namely, to obtain a more refined initial melt in sulfur and oxygen.

Metal oxides in the perovskite phase exhibit a number of interesting physical properties, including ferroelectric, dielectric, pyroelectric, and piezoelectric properties.
For the synthesis of low-dimensional nanostructures, a number of methods have been developed over the past decades.
In addition, this technique can also be used, with some limitations, to estimate the average crystallite or grain size of catalysts.
The activity of the catalyst was estimated by the number of produced products of the CO2 reduction reaction (mainly methanol CH3OH) per unit mass of catalyst per unit time recorded by a flame ionization detector of a gas chromatograph.
The most optimal reagent ratio is 1:1, due to the smaller amount of impurity in the resulting precipitate and the predominant number of nanofibers.
