In the Gate-VDD technique, the data in the standby time will be lost.
The drowsy cache technique can hold storage data in the sleep mode, so we will use drowsy cache to reduce the energy dissipations of the storage cell in this paper.
MTCMOS Technique for The Improved CAL Circuits MTCMOS technology is a leakage reduction technology in a lot of leakage energy reduction technique.
The 32×32 register file based on improved CAL circuits is shown in Fig. 3, which consists of a storage-cell array, address decoders, read/write word-line drivers, sense amplifiers, write bit-line and read data-line drivers, and a auxiliary clock generator that supplies auxiliary clock CX and CXb of the whole circuits, and its detail structure is similar to [8].
The results show that the leakage loss with leakage reduction technique can be reduced more effectively with not applied leakage reduction technique.

Based on the gas dynamic and geometrical parameters of a single flow jet engine one does a model of CFD data processing.
Finally one presents the contribution of chevrons in noise pollution reduction.
The variation of the immersing angle is the first parameter that contributes to the reduction of the noise pollution.
Causing a decrease of a few decibels, the chevrons can be a viable solution for the jet noise reduction in the vicinity of airports.

Finally, we introduce efficient TCB reduction.
If outside data or programs want access to the vault, they must pass muster with the TC system and obtain decryption keys.
Instead, they identify users, their computing systems (based on a unique identifying digital signature), and the applications or data they want to run[7].
In NGSCB and La Grande, it is incorporated into the main CPU, thereby avoiding the problem of unencrypted data going over the data bus to the dedicated processor[8].
The function of the analysis stage is to identify components that handle security-sensitive data or perform security- sensitive functions.

Due to the use of the single scan mode, in order to obtain complete and accurate mobile point cloud, a multi-angle scan for mobile phones and then using the data of the marking points for data automatic splicing is to carry on, and cellular phone multiple shots of the data is to the same coordinates.
Mobile data acquisition of point cloud is shown in figure 2, in order to more clearly display data result, in figure the point cloud has been color up, and the round hole is a landmark.
Point stage of processing is a combination of point cloud data, smoothes the point to get complete and perfect point cloud data, and is prepared for the polygon stage.
The basic process of data processing is as follows: alignment point cloud, item unless the connection and get rid of in vitro isolated point, noise reduction, unified sampling and packaging, and so on [3].
Aligning point clouds are scans of the original data with the purpose of Geomagic Studio coordinate system alignment, make it easy to determine coordinate in curved surface data transmission to downstream CAD software.

Through drilling powder of concrete surface at various depths,chloride ions’concentration at different depths of corroded samples were determinated, and the diffusion coefficients of chloride ion after 90,180,240 days of corrosion were calculated on the basis of Fick’s second law.It turns out that obvious convection zone exists in corroded concrete, and the thickness of conveciton zone increases with the erosing time and the reduction of concrete strength grade.In addition, fitted datas of chloride ion diffusion coefficient increases with the reduction of concrete strength grade.
The former is carried out in the natural environment, the main advantage is that experimental data is true and reliable,but long test period is needed.Therefore,experimental study mostly uses simulation test.
According to equation(2),the regression was carried out on the experimental data and by curve fitting of Fick’s second law of diffusion,the values of Dcl and Cs were determined.Besides,fitting needs to meet the condition that correlation coefficients R approach 1 as far as possible.The values of chloride diffusion coefficient Dcl and Cs are given in Tab.4.
The results of chloride diffusion shown in Tab.4 indicate that the chloride diffusion coefficient of the same concrete decreases with the time increasing.Also,chloride ion diffusion coefficient increased with the reduction of concrete strength grade.In addition,the surface concentration continues to increase.

The ETL process is equivalent to data preprocessing step of data mining including data clean, data transform and data integration etc.
Data mining can extract schema and discover knowledge in data from data warehouse which is not provided by data warehouse.
The model describes data relation in the form of data cube which allows user to observe data and model data from multi-dimensional angle.
Logic suggests that OLAP server provides multi-dimensional data from data warehouse or data mart for users, and need not consider how to store data and where data is stored.

The residual Young’s modulus data are presented in terms of normalized quantities.
Furthermore, establishing and interpolating of constant life diagram data using these methods is a tedious task, since they require a large collection of stress-life data to suit various wire rope designs.
These much-needed fatigue-life data are usually based on the data taken from available standards such as DNV OS-E301 [13], and the available literatures which are very limited.
The life data of the steel wire ropes at the various fatigue loading conditions is shown in Fig. 6.
The fatigue strength-life (S-N) data of the drawn steel wires is shown in Fig. 8.
