Mechanical properties such as ultimate tensile strength, percentage of elongation, yield strength, Poisson’s ratio and percentage reduction in area were found out.
The data is often used to specify a material, to design parts to withstand application force and as a quality control check of materials.ASTM D 638 specimens are placed in the grips of the universal testing machine at a specified grip separation and pulled until failed at test speed of 50mm/min for measuring strength and elongation.

Data hiding in the frequency domain takes
advantage of the insensitivity of the HAS to small spectral magnitude changes [2-4].
Quantization index modulation is another type of data hiding algorithms that increases the security of the augmented data at the cost of decreased tolerance to attack noise stronger than the watermark modulation.
The rank r of the factorization is usually chosen such that (n+m)rreduction is achieved.
The experiment results show that: On one hand, in this method, the watermark is registered to third-party website and not embedded into the original data, so there will not influence data precision and therefore keep the quality of original data well.
Zero-watermark extraction of local map would be useful for local data authentication.

Table 3 shows the Potentiodynamic polarization data.
This shows APN majorly influenced the O2 reduction and H2 evolution reactions.
The data depict the resilience of APN adsorption interaction mechanism on Al70 in HCl media.
The ∆G data shows there were no adsorption reaction mechanism between APN inhibitor and Al70 exterior as the ∆G data determined is significantly below the value range for physisorption, physiochemical and chemisorption reaction mechanisms hence lateral interaction effect is negligible [23, 24].

With the lightning position data in recent years of Jiangsu, satellite and live data on 3rd,July,2012, the reasons for the damage to office room equipment beside a communication base station in Wujin District, Changzhou were analyzed, and reasonable suggestions were given.
As the lightning location system itself had certain error, generally, meteorological data and the accident location was consistent which meant the accident was caused by lightning strike.
Fig.1 Weather on 3rd,July 1.2.2 Lightning strike probability After analyzing the data of lightning location system in Jiangsu province, we got that annual average flash density was 3.4 number/km2a, the average amplitude of lightning current was 31.93kA, 1% of the lightning current amplitude was more than 97.40kA in the range of 5*5km around the communication tower from 2006 to 2011.
Summary Commined with the lightning data in Jiangsu recent years, take the communication base station in Wujin as an example, this paper analyzed the accident from weather, lightning strike probability, lightning protection effectiveness, potential and current situation of lightning protection, the results are followed.

This research provides a new avenue for computational material science by integrating data-driven neural networks with fundamental physical models.
1.
Organization of the Text The success of neural network models heavily depends on the quality and quantity of training data.
Key steps include defining the CNN architecture, compiling the model with appropriate loss functions and optimizers, and training the model on preprocessed image data.
Data Augmentation (rotation, flipping, brightness modulation) are strongly required to prevent overfitting.

Predictions of the model were compared to the dispersive equilibrium model in the simulation of continuous separation process and validated with data taken for both compounds in a SMB experimental set-up.
To solve this issue many authors have formulated math models capable of predicting the SMB process of separation with statistically acceptable errors compared to experimental data.
Also shown are Perna [15] experimental data, for comparison.
This data was combined with mass transfer equations (Eq.1 and 2) employing a Langmuir kinetic (Eq. 5) and using the inverse tool, Random Restricted Window (R2W) [19].

The energy consumption and CO2 emission data is established to provide reference for future water resource research and government environmental policies.
Although the data does not show the actual amount of additives added in Kaohsiung plant, part of CO2 emission can be calculated from electricity consumption.
The results from this research can be combined with CO2 emission information of piped water for water conservation and sewage reduction analysis for various buildings[6].

Some of the major advantages of electric propulsion include:
- Reduction of fuel consumption by improved power flow control.
Lua is an extension language designed to support general procedural programming with data description facilities [11].
Regarding data acquisition, in order to achieve sufficient resolution of the computed parameters to be used as model outputs, a convenient rotor – input current space–time shift has been adopted.
In order to reduce the amplitude of the machine’s torque ripple a fractional slot number per phase and per pole can be used resulting in the reduction of the space harmonics of the stator magnetomotive force (MMF).
