Data evaluation is crucial for gaining information from sensor networks.
ML is a suitable approach for the evaluation of sensor data [4].
Hence, agents can carry learned models separating code (ML algorithms) and data.

The hot rolled sheets were pickled and subsequently cold rolled up to 0.5mm end thickness with 70% reduction.
The MTM-FHM software [10] was used to calculate the orientation distribution functions (ODFs) from the pole figure data obtained from the X-ray texture goniometer.
These materials were further cold rolled down to a reduction of 10% reduction.
After slight rolling reduction the surface was again examined in the x-ray texture goniometer and the phi2-45° sections are shown in figure 4.
The critical amount of light cold reduction @ 10% triggers the recrystallisation kinetics to lead the inward growth of surface grains along with their orientation at 800 0C.

Test results
By comparing the metallographic structure and fracture analysis under different multiples, according to the data of tensile strength, elongation, reduction of area and hardness.
(3) Elongation and reduction of area: the relationship between elongation, reduction of area and quenching water temperature is shown in Figure 4.
The reduction of area is the highest at 70℃.
When the quenching water temperature is lower than 70℃, the reduction of area increases with the increase of temperature, but when the quenching water temperature is higher than 70℃, the reduction of area gradually decreases.
In summary, the following conclusions are drawn: 70°C elongation, reduction of area, and tensile strength are the highest, and Brinell hardness is slightly lower.

The reduction effect of water pressure is more and more obvious from the tunnel crown to the elevation where the drainage holes are provided.
The reduction effect of water pressure is more and more obvious from the tunnel crown to the elevation where the drainage holes are provided.
Generally, for the invert is closer to the drainage hole, it enjoys better reduction effect regarding to the water pressure behind the lining walls than tunnel crown.
Nevertheless, for the water pressure behind the walls at the tunnel crown represents the overall characteristic of the water load reduction around the segment lining, it is still recommended to take the water pressure behind the walls at the tunnel crown as the reference for evaluating the reduction effect.
It is worth mentioning that: the quantitative data in this paper is gotten under special physical mechanics parameters for water head and wall rock, which can only be used as the reference for similar projects rather than for direct design.

Based on the data statistics at production site and the general rules for market transaction, the square metre, m2, of window is taken as the functional unit.
Data calculation principles
(2) The production data of steel lining adopt those of 100% carbon steel, about 10% of scrap steel is recycled during the production process of carbon steel, but no related data is found, so it is not considered in calculation
(5) Data on the assembling process of windows adopt the internal actual production data of enterprises.

This study will investigate data on changes in the atmospheric environment in Taiwan over the years, and will correlate them to temperature and relative humidity within the comfort range for human beings.
Therefore, a focused analysis of climate data can not only give building users a healthier and more comfortable environment to live in, but also help achieve energy conservation in buildings.
Data from the Central Weather Bureau (CWB) in Taiwan over the past three years (2011-2013) are also included in Fig.1 for comparison.

The experimental data were measured in transmission
and reflection arrangement.
The measured data are corrected, normalised and the experimental pole figures are calculated.
The experimental data were measured in transmission or reflection arrangement.
The measured data are corrected for absorption, irradiated volume, and they are normalised.
