The standardization and reference data for physical property evaluation are
necessary as well as the development of high purity materials by physical or chemical refining.
In this study, physical (thermal, electrical and mechanical) properties of Nb and Ta rare metals with various purities were investigated to obtain the fundamental data on the physical purity evaluation. 2.
This is due to the reduction of impurity effects on the electrical resistivity according to the Matthiessen rule [5].
Conclusions Physical properties of Nb and Ta metals with various chemical purities were investigated to obtain the fundamental data on the physical purity evaluation.

The wind angle and the size of the wind velocity were determined using data from weather stations near soundproof tunnels.
Five years (2005–2009) worth of weather data were analyzed for the areas with planned construction of a soundproof tunnel.
The maximum wind direction and average wind velocity is wind data of the recent five years at the nearby weather stations.
Fig. 1 shows the 5-year weather data from the weather stations.

The symmetry reduction caused by the periodic modulation/twinning of tetragonal lattice in nano- or mesoscale was ignored in the Refs. [5–8, 10, 13, 14, 17–24] and the equation (2) was used for the interpretation of experimental data obtained for the 5M martensite.

Apparently, leakage and dynamic power reduction are two distinct sets of techniques.
Therefore, there exist chances for dynamic application of standby leakage reduction techniques together with dynamic power reduction techniques to reduce total power in active mode.
This results in the reduction of total power.
However, the above-mentioned total power reduction methods are not suitable for low power multipliers design.
Power consumption measurements were derived from the netlists with back-annotated parasitic, using value change dump (VCD) data from simulation of 10,000 random input signals.

Fast data transmission put forward high requirements on network content matching (NCM).
As the I-DFAs are equivalent to NFA states, if the is too large, it will result in sharp reduction in processing rate.
STT gets the transfer results according to the input data, Inner Transfer will be send to the State Combine model directly and the External Transfer will be send to TSJ.
Experimental data is selected from snort_24, snort_31, bro217 and dotstar_300.
(3) States Reduction For different regex expression set, States Reduction performance of DC-DFA is validated.

Thus, the data on reduction of PNDA on the catalyst of the type Pd-GtK / B-094 shows, that modified catalyst of humic acid leads to the increase of the rate of reduction reaction of nitrocompounds.
In the medium of solvent during reduction of catalyst the swelling of surface-bound polymer chains occurs along with reduction of palladium with partial destruction of metal-polymer bonds.
Conclusion Thus, the experimental data shows, that the catalyst of type Pd–GtK/B-094 modified by humic acid leads to the formation of nanosized particles of active phase, which in turn leads to the increase of the rate of reduction reaction of nitrocompounds.
