The high precision multimeter connected to the computer to record the output signals for data processing and analysis.
Fitting the actual test data for linear, sensitivity can be measured.
Though dealing with the data, we get the results in Fig.7.
After we linear fit the actual test data, we can come to the slope of the fitted line were 6.065, 4.06, and 2.945.

Existing methods can be divided into two categories: geometric analysis[2-3] and data dimension reduction method[4-5].
Reduce Data Dimension: Principal Component Analysis, Manifold Learning Methods, Support Vector Classification (SVC) and so on are used to estimate head pose [6].
KPCA method can be applied to embed such potential structure to a low dimensional space to achieve high-dimensional data visualization.
Because data set higher than 3-dimensional cannot directly be perceived, we need to embed face images of high-dimensional manifold to less than 3-dimensional space.

It consisted of an air-source vapor-compression heat pump system and a measuring and data acquisition system.
The measuring and data acquisition system included a data acquisition instrument, various sensors and a central data processing computer, which could collect and analyze the measurements of temperature, pressure and power consumption.
The reduction of overall size was important to promote the wide application of heat pump water heaters.

Sunlight radiation resistant coating has the advantage of long-term weather resistance reduce the room temperature, Carbon reduction, surface contamination.
Currently, there are a lot of engineers or researchers the data results by PCIs to measure and propose improvements and to improve the quality of process capability and performance of the method [5,6,7].
First proposed the concept of PCI and developed a PCI Cp when data follows normality, which combines the process parameters with product specifications[9].
Step 2: UV radiation is known to collect building materials, paint quality characteristics of the total number of t's data.
Step 3: After collate the data to calculate the accuracy of UV radiation of building materials and paints P = σ / d and process accuracy index A = (μ-m) / d.

Experiments and determination of material parameters The basic micromechanical parameters for GTN model were determined from the measured tensile test data combined with the finite element calculations; generally 9 material parameters have been determined as described elsewhere [3].
To determine material curve for characterization of the elastic-plastic behaviour of tested material the standard tensile test data have been using for many years.
The standard CT specimens were used for the J-integral determination according the ASTM 1820-99a reduction in area [mm] procedure.

The best coincidence with the experimental data was obtained in case of the material curve adjusted by means of Mirone method from the tensile test of the standard specimen.

Through studying, associating and reasoning known experimental data, fuzzy inference system (FIS) of assist characteristic was established.
It consists of torque sensor of steering wheel, speed sensor, angle sensor of steering wheel, current sensor of motor, voltage sensor of motor, ECU, DC motor, worm reduction mechanism, etc.

Processability data showed that the saturation point for both fillers in rPVC was at 20 wt%, beyond which the composites became immiscible and sticky.
A recent report by Market Data Forecast in 2024 stated that the global market for PVC was valued at USD 44.38 billion and is predicted to reach USD 47.09 billion by 2025 and continue to rise up to USD 75.63 billion by year 2033 with a CAGR of 6.1%.
This data also shows that, LeHigh particles could disperse well and pose less tendency to agglomerate in rPVC matrix as compared to ALUM to produce a composite system with higher interfacial adhesion and interaction.
Particle Size Distribution of (a) ALUM and (b) LeHigh Figure 4 represents the thermal decomposition of both ALUM and LeHigh depicted by the mass loss percentage with the increasing temperature whereas, Table 4 shows the thermal stability data of both ALUM and LeHigh at processing and elevated temperature.

Model aromatic compounds, such as naphthalene have been investigated in order to gain useful data for the reaction mechanisms of the carbonization process [3].
During the first scan from +1.2 V to -0.4 V there is a broad cathodic peak from 0.1 V up to -0.05 V, which is characteristic for Pt(IV) reduction.
The peaks at more negative potentials (-0.3 V) are due to the reduction of H + and adsorption of hydrogen atoms on the Pt clusters formed.
During the forward scan (+1.2 V to -0.4 V), there is an insignificant change in the slope of the cathodic curve, which is not enough evident in order to be attributed exclusively to the Pt(IV) reduction.
Currents corresponding to the reduction of oxygen groups will superpose the current for Pt deposition.
