Background: Black spots are a major problem in commercial shrimp species and can have negative effects on shrimps' appearance, quality, shelf life, economic value, and product acceptance by consumers. This study was conducted to investigate the effect of orange peel extract on chemical and sensory qualities as well as black spots on Litopenaeus vannamei species of white farmed shrimp. Methods: ...

The aim of this paper is to propose a model of decision-making for lotteries. Lottery qualities are the key concepts of the theory. Qualities allow the derivation of optimal decision-making processes and are taken explicitly into account for lottery evaluation. Our contribution explains the major violations of the expected utility theory for decisions on two-point lotteries and shows the necess...

This paper describes the results of a simulation to demonstrate the principles and emergent intelligence associated with artificial life. Economic theory can be applied to artificial life in order to analyze and model adaptive or intelligent behaviors. This research is concerned with the principles whereby an animats competent for its resources, and so demonstrates intelligent behavior. This ap...
