Considering the uncertain feature in assessment, a new assessment model based on cloud theory that can realize greatly the conversion from qualitative conception to quantitative model is established. Evaluation model based on cloud theory can not only show the fuzzy feature of grade, but also indicate random attribute of the degree by hyper entropy. Take the assessment model into evaluation of water...
Focusing the optimal two-impulse transfer for fly-around orbit reconfiguration, an near optimal two-impulse analytical algorithm is presented by the CW equation and its solution. To avoid the singularity aroused from the normal whole solving method by CW equations, the paper calculates the out-of-plane optimal algorithm and in-plane optimal algorithm respectively in the deduction process and then...
Despite increasing work for describing gene functions using controlled vocabulary, natural language style gene functional annotations are most easily available and are most widely used by biologists. And intelligent analysis of these data in large scale is of great importance in the post-genome era. While the vector space model (VSM) based TF*IDF feature representation is widely adopted for text document...
