Dynamic features of a multimotor drive, quality of the process of its operation and its productivity are, first of all, predetermined by the technical data of the local electromechanical drives, such as controllability, stability, low vibration level, resistance to disturbances and so on.
An adaptive shaft speed correction system is provided for the improvement of the quality of the drive control and reduction of the impact of the elastic links of the mechanical part upon the quality of the control system [4, 5].
The printing shaft speed correction system, based on the principle of signal adaptation [4] (Fig. 1, the dotted line), was proposed for improvement of accuracy of the drive's operation, and reduction of the level of vibrations of the mechanical part.

In a different way, information redundancy technique creates additional information to the original data to accomplish tolerance.
Scheme 3: Majority-based convolutional encoder Since majority logic is the basic computing in QCA and is more reliable than the three-input AND gates when circuits get larger, we simplify the Eq. 2 with majority reduction [14]

The damage of water supply system may result in not only the reduction of water delivery capability and fire-fighting capacity but also the disruption of residential, commercial, and industrial activities.
In the event of an earthquake, water supply pipeline system may sustain various kinds of damage, such as pipeline ruptures and leakages, and result in reduction of water delivery capability.
The normal probability functions representing each of the damage states are expressed by Eq. 1 to Eq. 3, in which μR1, μR2, μs and σR1, σR2, σs represent the mean and the standard deviation (SD) of R1, R2 and S respectively. . (1) . (2) . (3) R1 and R2 can be estimated by statistical analysis of the past seismic activity data.

Lei Zhu and Ying Fan (2011) calculate the value of cost saving effect and amount of emission reduction in a coal-fired power unit with CCS compared to the existing coal-fired one without CCS.
For individual thermal power generation companies, they may either invest in CCS for reducing CO2 emissions, or purchase allowances to release CO2 emissions, if the former, then they should revenue from selling their emissions reduction, but they firstly need to determine when and which kind of CCS technology they will invest and select.
Because the carbon emissions trading market is a new one, there are not enough relevant data for making of CO2 price projections, so it seems reasonable to assume that CO2 price follows geometric Brown motion that is often used to describe the lone price process, then we express CO2 price motion rule by the following equation in this paper: (1) Where P is CO2 price, the drift, the variance, dw the incremental of standard Wiener process.

It is reasonable to point out that surface reduction of M5+-oxides with generation of a spectrum of lower valence states can be achieved by ion or electron bombardment widely used in modern electronic technology for surface treatments [16,17].
The effective displacement of valence electron density away from atomic nucleus results in reduction of electrical screening of inner shells with increasing of inner electrons binding energies for metals.
Earlier, this diagram was partly presented in Ref. 24 and now it is completed by new experimental data measured with XPS.

Talc treatment on former surfaces Obtain Contact angles of the coagulant solution on treated and untreated formers Measuring mass and thickness distribution of gloves produced by the formers Checking the physical defects of produced gloves Testing the mechanical properties of gloves Analysis of data Fig. 1 Flow chart of experiment Results and Discussion Contact Angle.
However, the overall palm thickness variance in Figure 2 demonstrated a slight reduction of film thickness in treated former.
This allows the coagulant coating to be distributed more evenly compared to the untreated former, resulting reduction in visual defects and heavier gloves, without remarkable compromises in glove thickness and mechanical properties.

With increasing Sc content a downshift and broadening of all phonons is observable, which is the consequence of the binding energy reduction seen in XPS and the increasing reduced mass.
The found B1Low mode is a forbidden mode and exhibits a true Voigt line shape in our data.
The observed bond softening is correlating with the reported reduction of the Young’s modulus while gaining the benefit of higher piezoelectric constants.
