Several algorithms for association rules are discussed which are AIS algorithm, SETM algorithm, Apriori algorithm etc. Their strengths and weaknesses are investigated. Their performance are compared and analyzed. Among all the algorithms, the most inefficient one is SETM algorithm but it is the most convenient one to combine DBMS.
Flexibility is one of important indicators for measuring the characteristics of supply chain; the author introduces and evaluates four ways of measuring the flexibility of supply chain by reviewing the research results of measurement model of flexibility of supply chain. Basing on this way, it builds a measurement model of flexibility of supply chain which… (More)
Efficient antigen presentation is indispensable for cytotoxic T lymphocyte (CTL)-mediated immunotherapy. B-lymphocytes propagated with CD40L have been developed as antigen-presenting cells (APCs), but this capacity needs further optimization. Here, we aimed to expand human B-lymphocytes on a large scale while maintaining their antigen-presenting ability by… (More)
