In this case methodology allowing reduction of manual data acquisition rate is required.
At the same time they generate new data resulting from the operation of control algorithms processing original data from primary sources, so they can be also considered as primary data source for another type of data.
In these methods worker intervention may be required, but it is minimized and the actions of the employee are supported with hardware and software solutions, that enable the reduction of the error rate of data acquisition and increase its speed.
Main MIAS subsystems are data acquisition, data integration and data archiving, sharing and presentation subsystems (Fig. 3).
Main functions of MIAS are: automatic or semi-automatic data acquisition from various sources, data integration (including data pre-processing and aggregation), data archiving in real-time, highly-maintainable database, communication interfaces between all elements of MIAS, data sharing and presentation, command channel.

Thus to meet mid-to long-term CO2 reduction targets, cost-effective CO2 separation technologies are key issue.
Table 2 summarizes literature data on the pros and cons of CO2 separation techniques [4-7].
The methods to calculate the costs for each of the cost categories and the entire data are drawn from them (Table 4).
The economic data of MA case are superior to MEA case contributed to the favorable operation and low solvent losses, meaning that using membrane gas absorption process can save the capture investment and reduce CO2 avoided cost.
Compared the data revealed in Fig. 3 and 4, effect of regeneration energy requirements on CO2 avoided cost is more sensitive than that of capital cost.

N2 adsorption/desorption data show that the highest surface area of aerogel fibers reached 241.6 m2/g with the average pore diameter about 10 nm.
With the reduction of the TiO2 content, the fiber continuity of the sample decreases, and the fracture becomes more severe.
With the reduction of the TiO2 content, the porosity of fibers increased gradually.
When MPVP: MTiO2 is more than 2.13, the porosity of aerogel fiber gradually decreases with the reduction of the TiO2 content.
The BET surface area, pore volume, and average pore diameter calculated from the N2 adsorption data are listed in Table 1.

Experimental Results Encouraged by the results obtained from preliminary simulation studies, the regulator and estimator algorithms were programmed using MATLAB/Simulink ® and implemented in the data acquisition and control board dSPACE ® DS1401 for further experimental investigations.
Both AVR systems have achieved a significant vibration reduction in the first eigenmode, which is important for riding comfort.
With this in mind, more effort devoted to the dynamic model reduction of distributed structures and to the development of adaptive regulation algorithms is required.

Table 1 – Characteristics of the products studied in this work (manufacturer data).
The features of the diffractograms indicate a reduction in the peak intensity of Co due to the increase in milling time.
Conclusions The results indicated a reduction of the particles size and spheroidization. as function of increasing of milling time, in a ball/powder ratio of 6:1.
The metal chips were reduced particle size, with respective reduction of the crystallite size on the order of 50% in 120 minutes of grinding.
