Fig.1 Diagram of electro-hydraulic hybrid brake system combined with ABS
There are three main operating modes:
Pressure reduction mode: When brake starts or the deceleration is mild, usually increase regenerative braking force and decrease hydraulic braking force.
The chart was established based on experimental data, as shown in fig.10.
Fig.9 Diagram of bilinear interpolation algorithm Fig.10 Pressure reduction/ boost interpolation chart According to four experimental points D11(P1, ∆P1), D12(P2, ∆P1), D21(P1, ∆P2), D22(P2, ∆P2), the corresponding duty ratio of PWM signal in point S can be acquired by bilinear interpolation.

The XRD data was acquired with the PANalytical Xpert Pro powder diffraction equipment at room temperature and measured using the Bragg-Brentano optical configuration.
This indicates the reduction of layered structure characteristics of the LixNi0.8Co0.2O2.
Higher Li content of Li1.1Ni0.8Co0.2O2 show lower specific capacity than Li1.05Ni0.8Co0.2O2 which may be attributed to the reduction of layered structure characteristic of Li1.1Ni0.8Co0.2O2 compared to Li1.05Ni0.8Co0.2O2 as shown in the XRD results.

However, before the capacitor is fully charged it already experienced a reduction in flow.
This is due to linearly increasing voltage resulting in reduction of current flow.
The calculation data obtained cell capacitance values (CSEL) is 0.7 M and the specific capacitance (Csp ) was 2.3 F/g .

When testing, the reduction rate of air pressure was recorded for air permeability test, while for the water absorption test, the volume of water penetrating into the concrete, at a constant pressure of 210-4 Pa, was recorded.
Three different positions were tested for every surface and the average data was implied.
Besides, the fly ash and slag will also result in the reduction of permeability in HPC which will make HPC denser and slower of hydrates, compared with NC.

Fig.1 Measuring installation position of camera Fig.2 Diagram of camber in mill outlet
Setting of correction model
Primary cause of steel plate camber is asymmetry in crosswise rolling status that will result in deviation of reduction in the direction of the width of strip.
Making , we can get the following formula: (4) (5) , (6) The rolled length that the distance of rolling mill is L on the both broadside is: , (7) The reduction is adjusted for correcting camber and eliminating the asymmetric factors so make and equal.
The steel plate is located in high precision sub-pixel with the image processing algorithm for providing the feedback data to the control model of correction camber. 2) The correction model of camber in heavy plate is constructed and the feedback control step of camber in heavy plate is proposed in order to achieve manufacturing and application control of rolled piece camber.

Natural dyes can decompose at higher temperature, leading to the reduction of dye up-take.
Taking energy saving and pollution reduction into consideration, 20 min of steaming time was proper.
The data in Table 2 showed that, the maximum absorption wavelength of mordant printing has changed compared with none mordant printing.

According to data from the World Health Organization, the death rate from chronic obstructive pulmonary disease is consistently rising, and the incidence of asthma in immunocompromised children and adolescents is also growing.
For larger particle diameters, meaningful reductions were observed depending on the high relative humidity and temperature increment.

EN data was analysed in the time domain.
Also, Rn results are compared with traditional Linear Polarization Resistance (LPR) data.
The EN data has been traditionally analysed by statistical and spectral analysis method, where the data of this last method has been performed by Power Spectral Density (PSD) plots.
A sampling rate of 1 point per second was used and each measurement consisted of 1200 data points.
