Many agent-based systems rely for their effectiveness on the intelligence of individual agents, and interaction among agents is required simply to coordinate these individually complex decisions. Specification and design methods for such systems focus on the internal architecture of individual agents. An alternative approach, “Synthetic Ecosystems,” uses relatively simple agents and draws heavi...

What would it be like to walk into a real-life “Holodeck” or “Cerebro” and experience a stunning new world unlike anything seen before? Beyond this, what if we were able to experience hitherto unobservable aspects of nature, as environments into which the body cannot actually venture? In fact, these questions are on the minds of scientists and artists working together, right now, in the AlloSph...

The systematic application of the synthetic ecosystems approach to the design of multi-agent systems is supported by the use of a generic pheromone infrastructure as extension of the runtime environment of the software agents. Using this infrastructure, insect-like coordination mechanisms may be applied in software systems. This article proposes an analytic model for such a generic pheromone in...

background: copper is a trace element vital to life, but the toxic effect of water pollution with it on fish is now exhibited. fish blood is susceptible to contamination-induced stress and its alternation due to the hematological and immunological parameters can be utilized as toxicity indices of xenobiotics. methods: in this study, juvenile species of silver carp with average weight of 200gr w...

Interest in arid ecosystems as a source of food supply for rapidly increasing population of the world, on the one hand, and the problems pertaining to the climatic characteristics, water shortages and soil sensitivity for the inhabitants in such areas, on the other have prompted efforts at both national and international levels to develop a better understanding of these problems as well as to f...

Abstract Despite the emerging body of literature on entrepreneurial ecosystems (EEs), theoretical development is still in its infancy. In this article, we explicitly draw upon analogy forest (FEs) with an EE to extrapolate regional ecosystem (REE) as alternate conceptual framework. The REE considers a region’s socioeconomic activity and stability performance whole, influenced by partitioned int...
