This article is a discussion of how the field of ecosystem modelling is being affected by the adoption of ideas arising from complex system studies. The modelling process is presented as being composed of four stages, starting with a modelled system, which is then depicted in turn by conceptual, representational, and computational models. The way that each of these stages is affected by concept...

Smart grid can be considered as a complex network where each node represents generation unit, producer, and links represent transmission lines. Agent-based modeling (ABM) is a paradigm represents a complex system of autonomous agents and their interactions with each other. Previously, numbers of study have been presented in smart grid domain using ABM methodologies. However, these study lack in...

This paper is concerned with the problem of synchronization for complex dynamic networks with state and coupling time-delays. Therefore, larger class and more complicated complex dynamic networks can be considered for the synchronization problem. Based on the Lyapunov-Krasovskii functional, a delay-independent criterion is obtained and formulated in the form of linear matrix inequalities (LMIs)...

The instability of international financial markets, as exhibited by persistent periodic crises, is an important issue for all market participants. This paper presents an alternative agent-based network theory of financial crises derived from recent developments in complexity science, and applies it to short-term currency crises. The theory, despite being parsimonious, is capable of generating c...

today, using new and renewable energy sources to replace fossil fuels is greatly expanded. the solar cells are devices that convert solar energy to electrical energy. solar cells based on organic materials, especially proteins, are one of these solar cells. for example, bacteriorhodopsin (br) which is one of the membrane proteins in halobacterium salinarum could be used in solar cells and parti...
