The use of n-tuple or weightless neural networks as pattern recognition devices is well known (Aleksander and Stonham, 1979). They have some significant advantages over the more common and biologically plausible networks, such as multi-layer perceptrons; for example, n-tuple networks have been...

A novel method was used to estimate natural mortality (M) of Kuwaiti Penaeus semisulcatus using tagging data. The new M estimator is based on two tagging experiments with similar products of initial survival after tagging times reporting rate, but with different total mortality (Z) values. The...
