Cristobalite aluminum phosphate (Cristobalite–AlPO 4 ) coating was deposited on SiC pre-coated C/C composites (SiC–C/C) by a pulse arc discharge deposition. The phase compositions, microstructures and oxidation resistance of the multilayer coatings were investigated. Results show that pulse arc discharge deposition is an effective route to prepare dense and homogeneous AlPO 4 coating...
A soft predictive model that based on Chaos-RBF neural network was proposed for the intake air flow of engine as its multidimensional nonlinear characteristics. First of all, the engine air intake flow time series with chaotic characteristics had been proved, the phase space of the original data had also been reconstructed before using RBF neural network to train and predict. And then the result had...
The Smart Client is a system of network distribution, one of which important advantages is occasionally connected. It allows users to continue working where it can not connect the network resources. This paper focuses on the service-oriented occasionally connected smart client architecture, data cache, data management and other key technologies. And through the application of worker examination management...
This paper introduces construction campus network group system design based on the basic unit of the campus network and on IP, proposed the development of remote information site, the network classroom, campus network groups and information center and for video monitoring in the case of large data flow requirements, the campus network video monitoring system cloud computing solutions and key technology,...
This paper summarized applications of Fire Wall in e-Commerce security system and have set forth choice principle on fire wall; have studied e-Commerce network security technique on Fire Wall; analysed constructing e-Commerce network security technology and applied to actual e-Commerce system design on power.
Wireless Mesh Network is a new broadband wireless network structure, That is, a high-capacity, high-speed distribution network, It is different from traditional wireless networks, can be seen as the integration of wireless LAN and mobile Ad hoc networks, and it played both advantages, is a wireless version of the Internet. Wireless Mesh networks are gradually expanding into the civilian commercial...
This paper describes several broadband IP network' key technologies (include ATM: asynchronous transfer mode, IP over SDH, IP over WDM and Gigabit Ethernet technologies) and solutions on e-government broadband IP network, and comparing, analysis to them. On this basis, proposed three-layer hierarchical structure design of construction e-government broadband IP network system on core layer, aggregation...
