To evaluate the scientific development performance of enterprises is an effective way to enhance companies' core competitiveness. Based on combination weighting, this paper evaluated four enterprises scientific development performance. The innovation points and contributions are in three aspects. Firstly, by determining the combination weight through the multiplicative synthesis method, it arouses...
Knowledge classification is a key step to establish enterprise knowledge bases. The business process oriented knowledge classification method is the most efficient way to integrate knowledge management and business process systems. The method is also oriented by knowledge application optimization. There are two phases, first of all, enterprise knowledge and business process pattern sets are expressed...
With the methods of geometry, sites' structure of HF air-to-ground communications and the sites-setting methods are studied. It is intent on putting forward ways and means to allocate sites of HF air-to-ground communications efficiently. After proving the theory that coverage efficiency of circles with the same radius is higher than the coverage efficiency of circles with different radiuses, the optimal...
According to the characteristics of present high frequency (HF) air-ground communications, this paper not only puts forward the function relation between aircraft flying position and time, but also proposes a new frequency choosing strategy according to SNR sorting. This new strategy based on ITS area SNR data ascertains the distribution of every channel's SNR along time on the route through interpolated...
A scheme for realization of intelligent passive optical access network (PON) is proposed, which can provide services for both security and self-locating physical faults by introducing a phase-sensitive optical time domain reflectrometer into the PON.
The analysis and verification of security protocols is an important field in the security of computer nowadays. Formal method has been advocated as an important means of improving the safety and reliability of software systems, especial those which are safety-critical. We propose a new simple trace semantics that can be used to analyse Cryptographic Protocols. Our technique support a protocol designer...
