The changes in crystallographic texture are investigated during recrystallization in 5182 and 6016 aluminum alloys, which were subjected to various cold rolling reductions.
The development of recrystallization textures is discussed based on experimental data and results of crystal plasticity simulations.
To the purpose of comparison between measured and predicted textures, the orientation data were post-processed with the MTM-FHM software developed by Van Houtte [2].
In the current investigation, the intensity of the rolling texture, which already pre-exists in the hot band materials A and B, increases considerably after the conventional cold rolling reduction.
A non-conventional type of recrystallization texture is observed in severely deformed material C (~94% rolling reduction), i.e. a relatively strong 20° rotated cube orientation has evolved.

Protection device dependent on local time benchmark, the use of MU inherent latency and link to reside the total delay ΔT reduction received multiple interval sampling data of the moment, on the basis of implementing protection control function.
Switches use a store-and-forward mechanism, after receive the complete data packet to forward data packets, and to support different rates port between the exchange of data message, keep high speed between the port and low-speed port work together.
Store and forward the data packet delay caused by the TSM related to data packet length, data rate r L, can be said for the TSM = L/r. 3)Message transmission delay of tp.
Delay calculation "Network mining network jump" mode, the sampling data packet transmission depend on the switch, and the message transmission delay is uncertain in the switch, so when the external clock loses, protective device cannot judge whether the sampling data synchronization.

Nanocontacts between fibrils and charge currents scattering features in strongly disordered polymers lead to essential change of character of low-temperature electric conductivity that allow from the data on electric conductivity to take the information on parameters of materials on the basis of conductive polymers.
The MIL matrix structure consists of two types of cages of 2.9 and 3.4 nanometer size, connected through a smaller windows (ca. 1.4 nm).[6] Our data confirms that the polyaniline is confined within MIL structure so the size of the conducting phase is limited to an order of several nanometers.
The powder X-ray diffraction data of MIL-101 (green), polyaniline (blue), aniline-impregnated MIL (pink), polyaniline@MIL composite (black).
The gas adsorption data and the pore size distribution analysis also confirm that the polyaniline in the composite sample is entrapped inside the MIL pores as we found the noticeable reduction of the pores sizes after the aniline polymerization, compared to the starting MIL-101 compound.
As can be seen from the data, the dependence of resistivity from current for all materials was observed.

The floor impact sound reduction amount of lightweight impact increases with a decrease in the dynamic stiffness.
The decrease in reduction amount implies a decrease in the floor impact sound insulation performance.
Examination of the characteristics for each frequency showed that the changes in the reduction amount were not significant with time at 125 Hz, whereas the changes in the reduction amount were significant at 2000 Hz.
The results of EPS-1 at 500 Hz in Fig. 2 indicate that the data between the initial two months exceeds -10 dB, and that the reduction amount increased with the elapse of time.
