Approach
A quantitative research based on data collection of the variables as potential of hydrogen, total
dissolved solids, turbidity, temperature and oxidation-reduction potential collected by the sensor network.
• ThingSpeak: It is an online platform which allows users to store data in the cloud, visualize the data and perform data analysis within the online site
These components are deployed directly within the water bodies or monitoring points to capture real-time data on crucial parameters such as pH levels, total dissolved solids, turbidity, temperature and oxidation reduction potential.
Cloud Layer Data Collection and Machine Learning Evaluation • Data Collection: We ensured that data was sent to ThingSpeak by guaranteeing the microcontroller an access point to upload data to the cloud
For data processing, the data is sent from the module to the ESP32 with serial communication (UART).

Meanwhile, it has some additional effects, such as cost reduction, energy conservation and emission reduction.
To effectively reduce the harms caused by the mechanical vibration and the noises in the operation of mechanical equipment so as to realize green production, it is quite necessary to make research on the vibration attenuation and noise reduction of heavy-duty machine tool based on non-obstructive particle damping (NOPD).
Thereinto, after the acceleration transducer inputs the signal collected by the signal collector into the charge amplifier, it imports the data into the computer to carry out data acquisition and record as well as waveform display and record.

Simulations has been performed using SIIMPL, a Monte Carlo simulation code based on the binary collision approximation, to predict experimental data and get a deeper insight in the channeling process.
Fig.3 Boron concentration versus depth in three 4H-SiC samples measured by SIMS. 50 keV 11B have been implanted at 200 °C along the [000-1] crystal direction The SIMS data are drawn as solid lines while MC-BCA simulations are given as dotted lines.
In addition to experimental data, the profiles have been simulated using the SIIMPL code.
Only a small reduction of channeling depth is revealed as the implantation temperature increases.
Summary In this study, we present experimental data and MC-BCA simulations for channeled implantations of 50 keV 11B-ions and 100 keV 27Al-ions in 4H-SiC along the [000-1] axis at different temperatures.

Data Automation Systems Data acquisition and data acquisition systems (abbreviated with the acronym DAS) typically involves the conversion of analog waveforms into digital values for processing [1].
The most common Data Acquisition System interfaces are the PCI bus, PXI bus, Ethernet, USB and Serial I/O.
This is considered to be very significant reduction of power by about 90%.

Statistical analysis of the experimental data.
Experimental data were analyzed by ANOVA (α = 0.05).
Analysis of the 24 h DC data (group mean values) revealed an average (80.2 ± 2.1) % of Resin/monomer EBPADMA TEGDMA HEMA MEP ETHMI 43.17 43.24 10.08 2.51 ETHMII 54.45 31.94 10.00 2.61 ETHMIII 62.85 23.22 10.36 2.57 vinyl conversion in copolymer series.
A maximum reduction in DC of 10.3 % established for unmilled ACP composites compares well with the reduction of DC observed in Bis-GMA- and EBPADMA-based binary and ternary resin composites utilizing the same type of ACP filler (up to 14.4 % and 14.2 %, respectively; [1]).
Utilizing milled ACP diminishes the reduction in the DC of ETHM composites (up to 4.6 %) compared to their copolymers.

The applicability of the mathematical model has been validated with experimental aging data, whereby a small deviation is observed between the two over a wide range of film thicknesses and reasonable intuitive explanation pertaining to the parameters is obtained.
The free volume reduction attributed to lattice contraction stops at a glassy value,. 2.
To demonstrate the applicability of the developed model, it has been validated adapting aging experimental data of oxygen permeability for bisphenol-A polycarbonate (BPA-BnzDCA) polymeric films by McCaig, et al. (2000) [9], as demonstrated in Fig. 2.
In addition, this contention has been further supported by McCaig, et al. [4] that a value of between 3 and 5 hrs is reasonable and gives agreeable accordance to aging data.
Therefore, there are remaining two parameters, and , left to be curve fitted employing two sets of experiment aging data at varying film thicknesses, which have been further extended to a wide range of thicknesses (0.25 to 33 microns) to verify the capability of the mathematical model.
