We provide a framework for hierarchical specification called Hierarchical Decision Process Petri Nets (HDPPNs). It is an extension of Decision Process Petri Nets (DPPNs) including a hierarchical decomposition process that ...

Because of the complexity of plant responses to water deficit, researchers have attempted to identify simplified models to understand critical aspects of the problem by searching for single indicators that would enable ...

With an increasing demand for electricity and the various concerns about the environment, increase of fossil fuels and energy security, increased the concern of producing energy from renewable sources. In 2002 was created ...

Complex systems often exhibit multiple levels of organization covering a wide range of physical scales, so the study of the hierarchical decomposition of their structure and function is frequently convenient. To better ...

This paper concerns mu-limit sets of cellular automata: sets of configurations made of words whose probability to appear does not vanish with time, starting from an initial mu-random configuration. More precisely, we ...
