Based on these results, the Coulomb friction coefficient between chip and tool rake was appropriately adjusted to achieve a sufficient correlation between experimental and computational data.
The obtained results revealed that the chip length reduction improves the cutting performance of coated tools and a significant increase of the removed material volume and material removal rate as well can be achieved. 1.
A further temperature increase results to a gradual but not linear reduction of the critical impact force and fatigue endurance stress.
These data were considered in the FEM calculations, which will be presented in the next sections. 2.
The input data are the undeformed chip thickness hcu, the cutting speed, as well as the coating, substrate and workpiece material mechanical properties.

This research based on the following sources: - data of Federal Service of State Statistics of Russia (RosStat) and the Territorial Department of the Federal State Statistics Service of the Astrakhan region (AstrahanStat) for 2011-2013; - regulations of the Astrakhan region in the field of social development for the period of 2009-2013; - official data from websites of the Astrakhan region; - sociological studies in other regions of Russia (Karelia, Chuvashia, Vologda, Kursk, Smolensk, Tyumen, Ulyanovsk, Perm) which participate in the national program "Problems of socio-cultural evolution of Russian regions" (2006-2007), as well as nationwide monitoring "Values and interests of Russian population"(2006).
The empirical data of the research based on the results of the monitoring survey conducted by research groups led by E.V.
Access to data array was allowed by the Corresponding Member of Russian Academy of Sciences Nicolay Lapin.
The comparative analysis of the all-Russian and regional data was performed.
The data obtained create the necessity to research the effectiveness of current transformation and to optimize further institutional reforms.

This experimental study has produced a systematic data set of the elastic modulus and fracture stress which contribute to the implementation of stress and strain analyses of SOFCs.
The experimental results demonstrated that there was a characteristic value of initial porosity above which the mechanical properties could be maintained during a reduction- re-oxidation cycle.
Deformation and Mechanical damage The data acquisition system employed in this study is described in our previous report [3].
Analysis and imaging of the obtained data were done by improving information technique, which are one of the techniques for wavelet analysis and location analysis.
Future efforts will focus on development of techniques for efficiently processing the huge volume of data, and investigating methods for automatic extraction of the period and features of valid signals, without setting threshold values beforehand.

Companies are reporting up to 80% reduction in errors when using virtual tests through the design process.
Results simplified neglected cruising data for having lowest values.
For each scenario, a set of data was generated.
The data sheets were then simplified and forces data plotted as shown in Fig. 4.

The data for different valve lift were regulated by the micrometer fixed on the valve rod and the maximum lift is 9.5mm. 1,5.
Data acquisition device Fig. 1.
Scheme of Steady Flow Test Rig for Port Validation Test Fig.2 is the comparison of simulated and experimental flow coefficient and angular momentum flux which shows that the computed values are coincidence with the measured data except the lower valve lift.
It can be seen that the axial deviation in both direction of the port could lead to a reduction of flow characteristics which change obviously with the distance increased.
Performance curve with the port rotated Conclusions (1) The calculated results are verified to be reliable by the measured data of steady flow test rig

Problems of data streams The fundamental limiting factor in transmission of data in general, the baud rate.
If you are satisfied with the picture quality on the level of a feature film to DVD5 (data reduction MPEG-2), will be sufficient flow of 3.5-4 Mb/s for one-way communication.
Fig.1 Logical connections videoconferencing network In terms of data transfer will not likely be able to keep the transmission delay below 250 ms.

For the latter one, the reduction of longitudinal and transverse geogrid ribs not only causes the decrease of friction and transverse rib bearing resistance, but also changes the mesh form which is the geometric structure of grids. 1.
SJW-200 consists of a rigid test box, a normal load system, a parallel load system, and a data acquisition system.
Ordinarily, data collected during large-scale pullout testing with SJW-200 included: (1) pullout force, (2) normal stress applied to the soil surface, (3) pullout displacement, and (4) displacements of measuring points, measured by encoders connected to the locations along the specimen using inextensible stainless steel wires.
From the data obtained in this study, it can be concluded that the pullout force increased with the rising of the transverse member ratio.
It can be seen from the figure that different ratios of longitudinal members had a great impact on pullout force which decreased with the reduction of the longitudinal member ratio.

With the increasingly stringent emission control regulations, selective catalytic reduction (SCR) technology is considered to be the most promising method in removal NOx from diesel exhaust.
Selective catalytic reduction (SCR) technology is considered to be one of the most promising methods.
Because of its advantages such as significant effect on NOx emissions reduction, better fuel economy and relatively insensitive to fuel quality and the high catalyst activity, it is considered to be one of the most cost-effective methods in removal NOx from diesel exhaust.
After data processing, the calculated injection pulse width is sent to the metering pump through CAN bus.
