In a chain of mutually coupled oscillators, the coupling threshold for synchronization between the outermost identical oscillators decreases when a type of impurity (in terms of parameter mismatch) is introduced in the inner oscillator(s). The outer oscillators interact indirectly via dynamic relaying, mediated by the inner oscillator(s). We confirm this enhancing of critical coupling in the ch...

Emerging scientific and engineering simulations often require the coupling of multiple physics models and associated parallel codes that execute independently and in a distributed manner. Realizing these simulations in distributed environments presents several challenges. This paper describes experiences with wide-area coupling for a coupled fusion simulation using the Seine coupling framework....

We present an electronical analogue circuit modelling a FitzHugh-Nagumo neuron with a modified excitability. To characterize this basic cell, the bifurcation curves between stability with excitation threshold, bistability and oscillations are investigated. An electrical circuit is then proposed to realize an unidirectional coupling between two cells, mimicking an inter-neuron synpatic coupling....

Coupling is the action of binding two entities so that they can operate together to provide new functions. In this article, we propose a formal definition for coupling and present a graph theoretic notation so that the side-effects of the creation of a coupling can be analyzed in a formal and systematic way. We then describe I-AM (Interaction Abstract Machine), a middleware that supports the dy...

The industrial wastes fly ash (FA) and polypropylene (PP) were used to develop novel green composites using a renewable, cheap coupling agent i.e. stearic acid. The fly ash (FA) particles were coated with stearic acid (SA) in different weight % like 0, 1, 2, 3 and 5. The SA coated fly ash particles were incorporated as filler in recycled polypropylene (RPP) matrix which was obtained from post-c...
