To guarantee the safety of big data calculation, the concept of security research and trusted cloud combined with large data security, a two-way defense system model of a large data calculation of SAT. The model of user data evidence through the dynamic safety factor; gradually determine the behavior of security permissions according to the reliability test implementation behavior. Provide the maximum-security...
Grain size distribution (GSD) is fundamental for soils and usually described by a set of graphic parameters (e.g., median size, kurtosis, skewness, uniform and curvature coefficient). Some probability distributions (e.g., lognormal and Weibull distribution) are used for special cases, but no general expression is available. In this paper we propose a general distribution form of P(D)=CD−μexp(−D/Dc...
Operating system platform of the intelligent equipment of current mainstream and traditional PC gradually evolved into Windows, IOS and Android camps. Among intelligent equipment, Android & IOS due to openess and flexibility got the initiative, while Windows has been in worse situation. But with the Microsoft Windows 8 & Windows phone 8, the pattern of the future may change dramatically...
As the maximum of viewpoint in each optical-plate unit attached with the mobile phone is fixed, when the bandwidth of wireless network is insufficient, the data of videos with the maximum viewpoints will not be transferred perfectly. The multi-view adaptive display method on optical-plate stereo mobile phone can increase or decrease the multi-view stereo videos according to the network bandwidth,...
This paper is on the multi-view stereo video display system on mobile phone. The key point is that the existing eight viewpoints display technology on optical-plate stereo mobile phone has an obvious but not very clear stereoscopic effect. Firstly, this paper does some research on parallax principle parallax corrector method and the viewpoints matching principle based on the multi-view image composition...
In this study, the removal of nitrobenzene (NB) in water using the microwave-enhanced H2O2-based (MW/H2O2) process and the influencing factors were investigated in common substances in the water. The results showed that in MW / H2O2 process, humic acid significantly inhibited the removal of NB, bicarbonate ions promoted the removal of NB, and the removal of NB in tap water is significantly better...
The dynamic testing system of voltage regulator must be assembled with the automotive alternator, so it's large, expensive, power consumption and operation complexity. A static testing system was developed by using electronic analog generator in place of automotive alternator sets. The system communicated with the computer can carry out performance test and data acquisition, in turn to analysis performance...
When wastewater is collected and deliver to sewage treatment plant in sewer network, there are occurring complicate process about physical, chemical and biological. It has great impact to organic removal and transformation efficiency where happened during the later treatment process in sewage treatment plant. This essay will describe water quality change in sewer pipe and the technology by using sewer...
Based on ECT technique and partial least squares regression (PLSR), a new voidage measurement method for gas-oil two-phase flow was proposed. PLSR was utilized to develop the voidage measurement models for given flow patterns. In practical voidage measurement process, according to the flow pattern identification result, a related PLSR based model was selected to calculate the measurement voidage....
