Grey theory, developed originally by Deng[2] , including systems analysis, data processing, modeling, prediction, decision making and control, is a truly multidisciplinary and generic theory that deals with systems that are characterized by poor information and/or for which information is lacking.

Abstract— The PAF model, which is one of techniques about the cost of quality (CoQ), has been introduced to the head stack assembly process in the hard disk drive industry.
Therefore, cost reduction can be arranged and set as measurable goals in terms of the effectiveness of the quality system [1].
Cost of quality before improvement Data before improvement Percentage of cost of quality per cost of finished goods PC AC FC COQ Product A 0.74% 0.32% 0.39% 1.45% Product B 0.48% 0.26% 0.37% 1.11% Identificaition for further improvements.
According to data analysis of the cost of quality, failure costs have been considered to find the opportunities in cost reduction.
If the improvement plans could be more effective, the rate of cost reduction will be more significant.

Huachun Pi1, a , Jingtao Han1, b, Chuanguo Zhang1, c , A.K.
Both models predictions in tensile deformation are reasonable agreement with the experimental data.
Early studies connecting EBSD data to crystal plasticity modeling used manual measurements to define initial orientations.
More recent work has taken advantage of automated data collection on samples as a means of collecting detailed EBSD data for modeling.
The purpose of this study is to model deformation texture development for pure Al using crystal plasticity finite element method with EBSD data.

Very few of them mentioned catalytic reduction.
Finally, the CTL signal was transferred into visible data shown on the computer.
A simple chemical reduction method was utilized in the synthesis of Al2O3/Pt particles.
Two experiments were carried out to investigate the effect of catalyst on catalytic reduction of benzene.

The reduction of graphene oxide (GO) to rGO is popular and attractive.
Hence, CARGO 180 shows a high degree of reduction among all other samples due to the synergistic reduction effect of cashew apple extract, which imparts i.e., a chemical reduction via various polyphenolic components in it and secondly, the high reaction temperature of 180℃ i.e., imparts a thermal reduction.
The d-spacing of the GO and CARGO 80 was calculated from HRTEM images using ImageJ software and was found to be 0.78 and 0.38nm respectively, which is in line with the data obtained from XRD studies.

In this paper, an efficient model is proposed to protect the data in the process of transferring data to the cloud and get the data from the cloud.
The project shifts to cloud computing will result in dynamic IT growth and in some reductions in some areas.
The first phase deals with the process encrypt the data and storing encrypted data into the cloud securely and the second phase deals with retrieving the encrypted data from the cloud and decrypt the data and verify the Integrity of the data.
Storing the data To shield the data in the cloud from the third party who may destruct the data on purpose, the data stored in the cloud must be in encrypted from.
As the owner takes some precautions such as encrypting the data to protect the data, the data are always under the threat of damage.

If the carrier frequencies are correctly chosen, the transmitted data can be entirely retrieved from the asymmetrically clipped signals with no in-band clipping noise.
The input data sequences X are multiplied by the M different random phase, and we must constraint on the factors in random phase vectors to ensure the multiplied vectors still satisfy the Hermitian symmetry.
Besides , it also needs to know the chosen random phase vector for correctly demodulating the received data symbols.
Therefore we improve the spectrum efficiency without declining the data transmission rate, but this will increase the mean transmission power.
