Then the rig was heated to 550 °C for 90 min and rolled to 55% reduction in thickness without lubrication in two passes.
These areas were fragmented by the SMAT process to ~200-300nm and the data was further clarified by TEM investigations.

The methods include pulse incremental interpolation algorithms and data sampling circular interpolation, which are mainly used in line, arc, parabolic curve and spiral line calculation.
Neural network has the characteristic of concurrent disposal, which can realize cycle-time reduction and increase precise.

The solid line in each figure is a parabola-wise fitted curve based on the experimental data and equation (1).
In this study, the experimental results demonstrated that an increase in the infiltration temperature resulted in a reduction in the viscosity of the molten glass with an increase in the liquidity, alumina surface wettability and infiltration thickness.

In addition, those factors such as increase of liquid load and weir height which increase froth height also increase entrainment, however, a reduction of tray spacing increase entrainment.
And correlations for pressure drop, weeping and entrainment of EJT were determined from experimental data.

Maximum lift coefficient and the critical angle of attack is almost the same degree of reduction, so before taking off evil spirits, clear ice accretion on the aircraft.

According to the Moscow and Samara aviation institutes reduction partiality from 1.0 to 0.15 in the axial microturbines leads to a decrease in efficiency from 0.75 to 0.50, which negatively affects the efficiency of the power installation as a whole, especially autonomous vehicles, as it reduces the level of autonomy, which is assessing the feasibility of the turbine installation.
Based on experimental data regression model was obtained.

Accordingly, reduction of (S)-phenylalanine 1 with NaBH4 and I2 in THF following Meyers’ method[3] afforded (S)-phenylalaninol 2 in 92% yield.
After column purification of the products, we compared the 1H NMR of 6a and 6b with the known data,[5] and all of spectroscopic supported the structure 6a is the syn product, thus confirm 6b is just the acetate anti product.

In this experiment, 752 UV-Vis Spectrophotometer (JINGHUA Instruments, Shanghai) was used to measure OD value of culture solution at 680nm and the statistic analysis of experimental data was performed by Microsoft Excel 2003 software. 1.3.3 Single-factor tests of nutrient stress Algal solution of Navicula sp. in the late exponential phase was centrifuged at 4000r/min for 5min, the supernatant was removed and the algal cells from the centrifugation substratum were inoculated in aquatic diatom medium that has no FeP3+P and Citric acid for 24h.
At the same time, this also causes the reduction of biomass of the microalgae.

The matrix of the game R=[rj(ν0,νj)] includes the values of a collision risk rj determined on the basis of data from the ARPA anti-collision system for admissible strategies ν0 of the vessel and admissible strategies νj for any particular j encountered vessels: (1) Number of the matrix columns R corresponds to the number of player A strategies (own vessel) – changes in course (,etc.), and changes in speed (, etc.).
(11) Control sensitivity and the changes of the process parameters Let p determine a set of kinematic and dynamic parameters of the process: (12) while p’ determine a set of the changed parameters of the: (13) Relative measure of the game sensitivity taken as the final deviation of the safe trajectory of the vessel Dd from the set trajectory will be: (14) (15) where: tw – advance time of the manoeuvre taking into account dynamic features of the own vessel, - duration of one stage of the vessel’s trajectory, Db – safe distance, Tb – safe time, DV – speed reduction
