Currently industrial automation systems are built using a hierarchical top-down approach, yielding tightly coupled and low flexibility systems. Holonic and intelligent agent-based industrial control systems have the potential to be much more highly robust and flexible systems with very loose coupling between subsystems. This paper explores Rockwell Automation’s current agent philosophy, applica...

The rational design, synthesis, and validation of a significantly improved insoluble polymer-supported siloxane-transfer agent has been achieved that permits efficient palladium-catalyzed cross-coupling reactions. The cross-linked polystyrene support facilitates product purification with excellent siloxane recycling. Drawbacks of a previous polymer-supported siloxane-transfer agent, relating to...

In this study, UV-curable urethane acrylate UA synthesized and then characterized by FTIR and HNMR. For better dispersion of nanoparticles in polymeric matrix, nano Al2O3 was modified by silane coupling agent and then its nanocomposites were prepared. The characteristics of synthesized nanocomposites were analyzed by TGA, DMA and infrared thermography. The results signify that adding nano Al2O3...

PP/sugarcane bagasse fiber composites were prepared by injection molding from two fractions of fibers with different particle characteristics. The mechanical properties the characterized tensile and impact measurements, while local deformation processes acoustic emission testing microscopy. determination dimensions after processing showed that considerable attrition takes place during melt in b...

Conjugation of haptens to proteins and enzymes is essential for the production of antibodies and development of ELISAs for these low molecular weight compounds. In this study, protein conjugates of several carboxylic haptens were prepared using the peptide synthesis reagent, 2-morpholinoethylisocyanide. The haptens included derivatives of benzimidazole and pyridoxine. The main advantage of this...

Motivatied by communication of mobile internet devices through a wireless network, we propose a moving agent network model with a network zone and consider synchronization of moving agents carrying a chaotic oscillator in a two dimensional space. We will theoretically and numerically show that synchronization of moving agents is dependent on the number of agents.

A fundamental problem for ecological and cognitive psychology alike is to explain how agents are situated, that is, functionally coupled to their environments so as to facilitate adaptive actions. Herbert Simon (1969/1996) argued that such coupling is artifactual (rule governed), being mediated by symbol functions and necessarily involving information processing. An alternative to this computat...

Cooperative Intelligent Transportation Systems (C-ITS) are complex systems well-suited to a multi-agent modeling. We propose a multi-agent based modeling of a C-ITS, that couples 3 dynamics (physical, informational and control dynamics) in order to ensure a smooth cooperation between non cooperative and cooperative vehicles, that communicate with each other (V2V communication) and the infrastru...
