High integration of electronic using hybrids and ASICs allowed to reduce the number of units needed to implement all the data handling, power distribution and attitude control electronics. 3) Uniform data flow design including satellite platform data and payload data.
Uniform data flow make the information transferring and information sharing convenient. 4) Enhance the processing ability for payload data and independent management ability. 5) Upgrade the information security management ability.
The equipment is composed of several modular modules with the same inner interface using inner data bus.
Firstly, we write data to RAM to verify the writing function and then read out the data from RAM to check the reading function, the writing data and reading data is compared to make sure the correctness of RAM.
ROM and EEPROM stores important software data so that they aren’t allowed to erase or reprogram entirely.

The results show that the higher annealing temperature, the larger oxidation/reduction peak separation.
The phase formation and transition temperatures observed in this work are in a good agreement with the literature data [31,32].
Their reduction- oxidation peak separation was approximately 0.273V and 0.697V, respectively.
However, reduction-oxidation peak separation of TNT/500ºC electrodes was approximately 1.905V.
The results of cyclic voltammetric tests show that a pair of oxidation/reduction peaks was observed and the higher annealing temperature, the larger oxidation/reduction peak separation.

The possibility of the reduction of the maximum and average error by means of the little changing of the value of the arc’s lateral deformation for a fixed traveling time is shown in this article.
There are the reserves to reduce the errors using the sigmoidal functions of specifying load’s path of motion with PID-regulators, which provide reduction of high-frequency load’s oscillations [4].
Fig. 1) the path of motion of point of suspension and cargo for raw data sx=5 m (sx k=sx); TP=25 s; l = 12 m; lx = 10 m, with a gradual increase in scaling and examples of the shortest distance li short determination is shown.
In Fig. 4, b the graphs of two separate functional dependencies Δmax(sx k) and Λ(sx k) for initial data sx=5 m; TP=25 s; l=12 m; lx=10 m were shown.
The parameters of input data [sx; TP; l; lx] in each experiment received the fixed values sx=5 m; TP=25 s; l=12 m; lx=10 m, with the exception of cases when any one of these parameters was being changed.

Analysis of surface roughness, burr on workpiece edges and cutter diameter reduction due tool wear was performed.
This research is one part of research on micro-milling of hardened materials regard to obtain of process prediction models, optimisation and micro-machininability data base development.
As the limit of tool diameter reduction can be take geometrical limit regard to process parameter or moment in time where is surface roughness sudden increasing over nominal values.
Fig. 7 Cutting tool diameter reduction (ap = 10 μm; fz = 8 μm; vc = 40m/min; MQL) Summary Analysing of machining process performance is very important in precision industry.
Base on experimentral data, modells and data base will be developed.

By using Rist operating line for the indirect reduction zone, as seen in Fig.2, direct reduction degree of the new process can be calculated, and thus indirect reduction degree can be obtained.
Direct reduction degree equals y-coordinate of point B. 3.
Theoretical analysis of model results 5.1 Data used in the model In this study, data used in the model are derived from a real operating blast furnace in China.
Set VRG-h as 250 m3/thm, and keep other data unchanged.

Data from [1-6] The application of materials based on silicon carbide should be a solution to many of the shortcomings that arise from the use of conventional materials.
The measured data are provided to the polishing machine, which processes the sample with respect to the data.
Analysis also shows the critical points and the possibilities for mass reduction; 4.
The results correspond to the conclusions drawn from the data in Table 2.

To accomplish this, stage-wise quantity information of life cycle and energy consumption data were established on major materials through theoretical consideration on life cycle assessment.
Actual monthly data was used to compute mean annual data.
Mean annual electricity use and photovoltaic production of unit household in passive apartment were assessed using actual data about additional electricity use with consideration on loss rate.
Equipment used for demolition of building and fuel consumption used for transportation was used as data.
Fuel consumption of demolition equipment according to material quantity was used as data.

This process enables significant reduction of tool-path necessary for machining these shapes which also leads to reduction of the working time.
Data from CAD software in the STL format were used for this calculation.
The data are formed by Cartesian coordinates of vertex points and normal of each of the triangles in the given network.
This software enables loading STL data of general surfaces.
The described processed algorithm enables loading data in STL format.

Torsion simulation produces torque and angle data which are converted to stress and strain [2,4].
It can be noted that the torsion simulation showed differences of less that 10% when compared to the MFS calculated from rolling mill data.
Pass Mill MFS (MPa) Torsion MFS (MPa) Difference (%) 1 123 113 8 2 161 150 7 3 138 147 -7 4 163 163 0 Such data are of great importance when setting up the mill parameters prior to first rolling as well as to fine-tune on-going hot rolling schedules.
