This paper discusses an approach to multi-document summarization that builds on understanding word as feature deeply. We created 7 basic word features using the frequency, position information, event information and topic information. Then choose logistic regression model to compute words value. The summarizer gives a score of sentence by words value, and combines score and redundancy of sentence...
Taking the ramjet extended range projectile as the research subject, in order to improve the total pressure recovery coefficient, the parameter model and numerical simulation to the flow field of inlet have been assembled by the auto-optimization platform, simulated annealing technique has been used to optimize the cone angle of simple cone and double angle cone based on the highest total pressure...
