Processing and interpretation of magnetic data usually require information of total magnetization direction.
Introduction In mineral exploration, data processing and interpretation of magnetic data, such as reduction to pole, forward modeling and inversion, usually require known magnetization direction.
Test on synthetic data To test the CMD method, we designed a model composed of four distinct prisms.
And then we estimated the magnetization direction separately from data in each block by the CMD method.
Tests on synthetic data indicates that this method is reliable and effective.

Reduction of cost of such end mills while maintaining their key performance characteristics is an important and long-running task.
In the process of selecting the optimum conditions for cutting and tool geometry, data from papers [1-11] were used.
Results and discussion of experimental data The results obtained allowed to formulate the following conclusions: 1.
Such parameters as cost, tool life, tool wear rate or their correlation (these data are not presented in this paper because of limited volume) do not allow making an unequivocal conclusion.

The last proved to be dependent on the stent diameter reduction, rate and location of restenosis.
The data points are found to be below the Findley's criterion line, as plotted in Fig. 5.
Data points depicted in Fig. 11 show that the two geometries have similar behaviour in terms of their von Mises stress vs. the radial displacement.
This effect is better observed in Fig. 14 where the data points corresponding to the eccentric restenosis are found to be always above the first bisector.
Moreover, for the same diameter reduction, the eccentric restenosis is found to be more harmful than the concentric restenosis.

The build-up phenomenon and its influencing factors like principal axis speed, axial feed rate and wall thichness reduction were investigated using the finite element method (FEM).
But the determination of technical parameters of backward ball spinning depends chiefly on technician’s experience and lots of trial and error because there is no adequate available data.
Proper selection of technical parameters like principal axis speed, axial feed rate and wall thickness reduction is vital to manufacture the spun tube product with desired surface quality and dimension precision.

Taking the product quality and manufacturing efficiency into account, the proper axial feed rate and wall thickness reduction were in the ranges of 0.5 to 0.8 mm /r and 25 to 30%, respectively.

Generative models are probabilistic representation of data that can be regarded as the generator of observed data.
To explain the data effectively, the probability models must be able to 1) reduce the complexity of the original data; 2) make abstraction and simplification in some extent.
Generation model can generate random observation data in condition that latent parameters are given.
It is used to describe the "co-occurrence" of data[7].

It has been recorded that more than 90% reduction of residual stresses were observed in a pre-stretching rage of 2-3%.
The experimental data of the ultrasonic and the crack compliance methods were found to correspond well with the simulated models.

It can be found that the quenching residual stress has obvious reduction after pre-stretching in the Fig.3.

Introduction Traditional noise reduction methods for the cab of the truck include vibration isolation, sound insulation,noise reduction,sound absorption and so on.These passive noise control methods have a better control effect on high-frequency noise in the cab , while the low-frequency noise can not be effectively controlled.With developing of the electronic and control technology , Active Noise Conrtol is applied to the field of reducing low-frequency noise of interior cab.
And import the reference signal data into MATLAB/Simulink.A forward AANC system is established according to the block diagram of Fig.4.
Especially in the frequency of 55Hz, 120Hz, 420Hz , the reduction effects are better.And it also can be seen that the system has a good convergence and stability from the time domain curve in figure 7.
Fig.10 Time and frequency domain curves（Before controlling） Fig.11 Time and frequency domain curves（After controlling） From Fig.10 and Fig.11,we can see that the noise is also reduced obviously.But the reduction effects is not so good compared with feedforward AANC system.
Conclusions From the simulation results,we can see the two systems all work on low-frequency noise in truck ca- b, but the former has better reduction effect and stability than the latter.

Yield-strength reduction factor, R is the ratio of elastic strength, of of the elastic SDF system to yield strength, yf .
But this data is not present here.
A more significant reduction in the median RC is observed in short period systems having small α [Fig. 2(a), 3(a)].

This study observed that the median RC is significantly influenced by the change in post-yield stiffness ratio, damping ratios (≤5%) and yield-strength reduction factor in short period systems.

The Liquid Petroleum Gas can be use for diesel engine fuelling with significant result in term of pollutant emissions improvement, with important reduction of nitrous oxides and smoke for a LPG dual fuelled diesel engine.
Thus, based on the experimental data, an evaluation model for mixture forming was developed for an automotive diesel engine fuelled with LPG and diesel fuel by diesel-gas method.
(4) where: minj is in-cylinder injected fuel mass, m in-cylinder injected fuel mass and unformed as mixture, p oxygen partial pressure, C model calibration parameter with experimental data.
The ws values registered for dual fuelling are all superior to diesel fuelling values, the increase being correlated with the previous observed reduction tendency for vaporization and combustion times.
The reduction is up till 4% for the xc percent that registered also the most reduced vaporization time, Fig. 1.a.

The method of calculation of economic efficiency of concrete by means of reduction of total construction weight and increasing of floors’ number is proposed.
It is shown that economical calculation for developed material which is based only on the cost of the material itself does not allow to obtain adequate data concerning prospect and competitiveness of the material.
Calculation is based on the reduction of the total weight of heavy concrete products, which in turn based on the assumption that reducing the load on the bases and foundations allows increasing the number of floors of the building which leads to more useful ground space utilization and to the reduction of costs per construction of unit area.
So, when using high-strength lightweight concrete of strength class B50 and A400 reinforcing steel rebar the reduction of consumption of 30% can be achieved.
Designated approach allows us to conclude that the direct calculation of the cost of the material by the prime cost does not provide objective data concerning the prospects of the development and its competitiveness.
