Spreadsheet is one of the most commonly used end user programming environments. As such, there has been significant effort made by researchers and the industry to develop techniques and tools to improve spreadsheets. In the course of developing spreadsheet-based applications in Chinese governmental projects, we found that enabling end-user to program on the all-in-one, hard-to-validate Chinese spreadsheet...
Grey theory has been applied widely in the field of prediction and decision, but model precision is influenced extremely by sequence smooth degree, boundary condition and background value. Genetic algorithm has well effect in searching for best result because it is an effective way. The paper advances a new method, sin function is used to deal with sequence, and genetic algorithm is used to optimize...
This paper proposes a multi-agent model for the studying of the self-organization teampsilas behavior. The model is dependent on the interaction rules and the decision factors of team members. Three kinds of team members (reciprocators, cooperators and selfish) are proposed in the paper. The team members work with one of three work attitudes (diligence, average, shirking). A small-world network is...
In this paper, a low-complexity power-efficient iterative detection scheme for differentially encoded MPSK transmission over AWGN and Rayleigh fading channels is presented. As the main contribution, a novel APP coherent demodulator, which well suits for iterative processing, is derived under the optimal bit-based MAP criterion. The implementation of iteration is not trellis-based, and needn’t reconstruct...
