Currently, these roll bite peaks are approximated with Heat Transfer Coefficients ‘HTC’ macroscopically tuned on measured mill data.
Temperature signals during rolling have been stored using a data acquisition system (16 bits–sampling frequency: 3-5 kHz).
Evaluation of roll surface temperature and heat flux by inverse calculation (model n°1) Influence of strip reduction.
This trend is due to the higher heat dissipated by plastic deformation corresponding to the higher strip reductions.
HTCroll-bite as a function of strip reduction.

Shear modulus reduction and the two shear threshold strains
Dynamic shear modulus reduction are plotted in Fig. 4.
These results are consistent with the data for noncohesive soils obtained indirectly by Hsu and Vucetic[3].
The newly obtained data in Fig. 4 are obviously in broad agreement with the previously published results by Hsu and Vucetic[3].
Comparison between the second threshold shear strain values and shear modulus reduction curves obtained confirms that the soil behavior is considerably nonlinear at.
RELATION BETWEEN SECANT SHEAR MODULUS REDUCTION AND THE TWO SHEAR THRESHOLD STRAINS Conclusions This paper carries on dynamic constitutive modelling by use of thermodynamic approach.

The
characteristic parameters of the migration of this boundary - activation enthalpy and preexponential factor - were determined
and are discussed in context of the previously obtained data.
Results and discussion The annealing of the sample promotes the reduction of the grain boundary energy via the reduction of its area.
Obtained data were analyzed assuming the migration velocity v is defined as m MF dt da v == (1) where M is the grain boundary mobility which depends on the annealing temperature T, F is the driving force and m is the exponent.
Obtained data are summarized in Table 1 and the temperature dependence of Mγ is shown in Fig. 3.
These data are comparable with those of other special grain boundaries.

Abstract: The wavelet packet transform is a new time-frequency analysis method, and is superior to the traditional wavelet transform and Fourier transform, which can finely do time-frequency dividion on seismic data.
In some conditions it requires some data processing in order to suppress the noise to improve the resolution of seismic data when relying completely suppress random noise in field is not possible.
Wavelet analysis has been applied in the seismic data.
Wavelet packet[4] was used for multi-resolution analysis to seismic data, not only low-frequency seismic data were done continuous decomposition, but the information lost in low-frequency is also decomposed, in order to achieve more precise decomposition method than the wavelet analysis to meet the time field seismic frequency component precisely division.
A research on the noise-elimination method of pre-stack seismic data by wavelet packet transform.

On the basis of the carried-out experimental research and the literature data the key points concerning the required properties of modifiers have been formulated.
As we can see from these data, the good agreement of the dosage, calculated according to the adsorption data, and the optimal dosage according to the rheological data is observed.
So, reduction of the plastic viscosity value will reduce the load on the electric motor of a concrete mixing machine.
The good agreement of the dosage, calculated according to the adsorption data, and the optimal dosage according to the rheological data is observed.
This is expressed in the reduction of the most probable diameter of particles from 13–16 µm to 3–5 µm.

Therefore it is vital to define to what extent the change of unit
pressure will influence reduction of surface roughness of intermetallic coatings.
The increase of unit pressure exerted on coatings surface causes the reduction of its roughness.
The influence of unit pressure on intermetallic coating surface roughness reduction ratio is provided in Fig. 2.
Higher values of surface roughness reduction ratio were measured for intermetallic Ni3Al coatings.
On the basis of the data included in Table 1 and in Fig. 3 it is possible to conclude that a considerable improvement of surface adhesion took place after plastic working, which was demonstrated by curves of the bearing area.
