Everyday uses of the notion of institution and some typical institutions have been studied and formalized by economists and philosophers. Borrowing from these everyday understandings, and influenced by their formalizations, the notion of institution has been used within the agents community to model and implement a variety of socio-technical systems. Their main purpose is to enable and regulate...

In this research, effect of nanoparticles dimeter on free convection of aluminum oxide-water was investigated in a cavity by single phase and two phase models. The range of Rayleigh number is considered 105-107 in volume fractions of 0.01 to 0.03 for nanoparticles with various diameters (25, 33, 50 and 100 nm). Given that the two phase nature of nanofluids, necessity of modeling by this method ...

Nowadays, workflow processes are mostly built out of the designers' experience, which is usually full of skills and tactics and the correctness of the resulting processes is hard to guarantee, especially for complex ones. To address this issue, a tool called AAWM (Agent Aided Workflow Modeler) is proposed. This paper details the design and implementation issues related to AAWM such as system ar...

A standard way of describing requirements for system design is according to function. One describes high level functions of the operation of the system and decomposes these into lower level functions which perhaps overlap. For complex systems the number of functions can be large and they may interact, making it important to have a methodical way of describing the structure of functions and thei...

The theory and practice of agent-based modeling is reviewed, and agent-based modeling toolkits are evaluated and discussed. A tractable selection of toolkits, RepastPy, Repast Simphony, and breve are then employed to develop and visualize a series of increasingly sophisticated agent-based models, starting with a simple network-interaction diagram and proceeding onto the Boids 3D flock simulatio...

This paper presents a simplified form of UML state diagrams for modeling agent mobility. Mobile agent has gained more importance technology. The notations used to model agent mobility are focused on capturing agent creation, mobility paths and current agent location. In this paper, we demonstrate how the simplification of the state UML 2.0 Activity Diagrams can be used for modeling mobile agent...
