an optimal desirability function method is proposed to optimize multiple responses in multiple production scenarios, simultaneously. in dynamic environments, changes in production requirements in each condition create different production scenarios. therefore, in multiple production scenarios like producing in several production lines with different technologies in a factory, various fitted res...

A bibliometric analysis was applied in this work to evaluate global scientific production of geographic information system (GIS) papers from 1997 to 2006 in any journal of all the subject categories of the Science Citation Index compiled by Institute for Scientific Information (ISI), Philadelphia, USA. ‘GIS’ and ‘geographic information system’ were used as keywords to search parts of titles, ab...

Filtering plays an important role in the Internet security and information retrieval fields, and usually employs multiple-strings matching algorithm as its key part. All the classical matching algorithms, however, perform badly when the number of the keywords exceeds a critical point, which made large scale multiple-strings matching problem a great challenge. Based on the observation that the s...

among the ways of pigment production, microbial synthesis has gained more interest for high growth rate, easy extraction and high yield. pigments are used in the food industry as natural colorants and preservatives; they also have pharmaceutical applications. in this study, fungus monascus purpureus ptcc 5303 was used to produce red, orange and yellow pigments. at first, significant variables w...
