چکیده

In this study, it is aimed to compare the yield and strength of crayfish fyke rigged with knotless net 210d/12 rope thickness those traditional material 210d/6 knotted which widely used in Turkey fishing (Pontastacus leptodactylus, Eschscholtz, 1823). The study was carried out on a monthly basis between June 2017 May 2018. total 300 nets, equipped 150 classical alternative were used. caught crayfishes measured weighted according they in. A 3509 caught, 1465 2044 net. Average CPUE value ranged from 10.93 (g/fyke net/day) 281.14 for per operation. gear found be 98.34 , while that determined as 79.46 net/day), no statistically significant difference average values (p>0.05). (± SE) 10.43 ± 0.27 kg, 210d / 12 identified 14.50 0.91 kg (p<0.05). Although has high strength, since lower by 19.20% compared gear, believed its use will not profitable.

Neural Net and Traditional Classifiers

Previous work on nets with continuous-valued inputs led to generative procedures to construct convex decision regions with two-layer perceptrons (one hidden layer) and arbitrary decision regions with three-layer perceptrons (two hidden layers). Here we demonstrate that two-layer perceptron classifiers trained with back propagation can form both convex and disjoint decision regions. Such classif...

Project Portfolio Selection with the Maximization of Net Present Value

Projects scheduling by the project portfolio selection, something that has its own complexity and its flexibility, can create different composition of the project portfolio. An integer programming model is formulated for the project portfolio selection and scheduling.Two heuristic algorithms, genetic algorithm (GA) and simulated annealing (SA), are presented to solve the problem. Results of cal...
