—A new scheme to obtain optimal fuzzy subsets and rules is proposed. The method is derived from the use of genetic algorithms, where the genes of the chromosome are classified into two different types. These genes can be arranged in a hierarchical form, where one type of genes controls the other type of genes. The effectiveness of this genetic formulation(More)
1151 model for out-of-sample drive signals and express this error in terms of signal-to-noise in column five. We calculate the signal-to-noise ratio using SNR = 20 log 10 std(actual) std(errors) dB: (13) We show the analogous results obtained by reconstructing and testing static models on the same data in the remaining columns. Typical results are presented(More)
In order to assess the digestive physiological capacity of the American shad Alosa sapidissima and to establish feeding protocols that match larval nutritional requirements, we investigated the ontogenesis of digestive enzymes (trypsin, amylase, lipase, pepsin, alkaline phosphatase, and leucine aminopeptidase) in larvae, from hatching to 45 days after(More)
The effects of salinity on survival, growth, special activity of digestive enzymes, nonspecific immune response, and muscle fatty acid composition were evaluated in the American shad (Alosa sapidissima). Juveniles of 35 days after hatching were reared at 0 (control), 7, 14, 21, and 28 ppt for 60 days. At the end of the experiment, juvenile American shad(More)
Facebook is currently the most popular social networking service in the world. With such tremendous influence on community networks, Facebook has been attracting considerable attention both from the media and academia. A review of the literature indicates that most researchers are concerned primarily with the influence of personal traits on online(More)
