Nuclear reactor multiphysics via bond graph formalism
… nuclear reactor multiphysics problems using bond graphs. Conventional multiphysics simulation paradigms normally use operator splitting, which treats the individual physics separately and exchanges the information at every time step. This approach has limited accuracy, and so recently, there …

Investigation of bond graphs for nuclear reactor simulations
… multiphysics nuclear reactor problems using bond graphs. The conventional method of modeling the coupled multiphysics transients in nuclear reactors is operator splitting, which treats the single physics individually and exchanges the information at every time step. This approach has limited …

Design and Test of an Automotive Clutch Actuation
… very complex. The system was modeled using the Bond-Graph technique which allowed the drafting of the dynamical system equations, in state space form. In fact the system itself is quite complex due to the fact that multiple dynamic domains were taken into account. The result is a unique model …

A reduced order systems approach to prediction of emergent behaviors of biological systems
… matrix is created in three steps. First, using Bond Graph Theory, a set of independent state equations(derived from the bond graph) may be augmented by adding equations using auxiliary variables necessary to "sufficiently inform" the nonlinear dynamics. This creates an augmented state space …
