The emission spectroscopy data confirmed the presence of different reactive species in the discharge gap.
The most common applications of plasma surface treatments include: the cleaning of surfaces, sterilization, increasing the wettability and adhesion of polymers, reduction of friction, and more recent, the improvement of cell attachment in tissue culture studies or the alteration of surface–protein interaction.

Mathematical relationships between selected primary variables and secondary variables were given with existing data from references.
On the basis of existing data from reference materials, the mechanical behaviour of concrete at a temperature over 400℃ will be focused and a simplified model will be established.
With the assumption of the zero velocity for the solid skeleton , there is (3) Consequently there is (4) For liquid water, the macroscopic mass conservation equation is: (5) where Sw is the volume fraction of liquid water of the pore space (i.e., liquid water saturation), is density of the liquid water, is the density change of water due to evaporation of liquid water, and it represents that reduction of the density of solid phase; The above Eq. 5 can be alternatively written as (6) Mass conservation equations for gaseous phases.
In order to simplify the problem, empirical expressions have been adopted for evolutions of some internal variables on the basis of experimental data.

New crown complexes with biological prop ethers have been created, and the structure of the produced crown complexes has been determined using elemental analysis data from studies of these samples' IR, mass, and NMR spectra.
In Fig. 3 presents experimental data for tetracycline, from which the degree of extraction increases from 84 to 96% with an increase in the mass of the sorbent to 20 mg; a further increase in the mass of the sorbent does not affect the degree of extraction.
As can be seen from the data given in the table, with a corresponding increase in the phase contact time, the degree of tetracycline extraction does not change, which makes it possible to achieve high concentration factors (n·103).
The experimental data obtained in the work indicate that all the studied tetracyclines are sorbed on magnetic HCPS in neutral: quantitative sorption (96 – 98%) is observed in the pH range 2-7 in the region of dominance of this form.

In scarce data contexts, they are ineffective.
The data is processed by the recommendation engine in three stages: data gathering, filtering, and recommendation
The dataset is split into two sections: a training set that contains 75% of the data and a testing set that contains 25% of the data.
However, the proposed method discovers better indirect correlations in data and uses biclustering for dimension reduction.
CBCF only uses data from one dimension and ignores data from other dimensions.

These PDFs can be based on experimental data or on theoretical assumptions
� The desired result is derived from analysis of the response data from the simulations performed in the above step.
The most important factor in springback data is the accuracy of the forming simulation.
Particularly, can be observed a reduction of the analyzed responses for an increase of the anisotropy coefficient.
It will be necessary to go on with this experience including an experimental test case in order to evaluate the correlation between the simulation data and the experimental ones for a given test case.

Several case are studies in marine concentrated corrosion, and corrosion rate measurements in steel sheet pile walls in a marine environment, and much debate on whether a corrosion model should rely on mechanistic principles or actual corrosion data collected from structures marine surveys [15].
Empirical models Assuming a constant corrosion rate from the various corrosion mechanisms and the scattered corrosion data available within the published research literature, seems insufficient to predict the corrosion damage for certain structures as ships age [15].
In Paik and Thayamballi model [21], the coating duration was described using a lognormal distribution: dt=C1 (t-T0-Tt)C2 (4) Where obtaining C1 and C2 is based on collected statistical corrosion data.
However, this model was fitted to an assumed corrosion data set instead of real measurements, which makes it difficult to determine the degree of accuracy and rationality as reported in researches [15, 18, 19, 24, 25].

Programmable Logic Controller (PLC) or Programmable Controller (PC) was developed from the traditional relay logic control system in the late 1960s, since then it has been rapidly enhanced, especially in data processing, network communications and integration with DCS systems, etc.
Through the HMI we can edit, download the recipe data to show that the key processes parameters, historical data and real-time data curve, meanwhile HMI can be communicated with main controller by using serial RS-485/232 serial port communication.
Thus, enegy saving, cost consuming and noise reduction can be easily got by this equipment.
