How does one derive models of dynamical feedback effects in multiscale, multiphysics systems such as wave mean flow interaction (WMFI)? We shall address this question for hybrid systems, defined whose motion can be expressed the composition two or more Lie-group actions. Hybrid abound fluid dynamics. Examples include: dynamics complex fluids liquid crystals; wind-driven waves propagating with c...

This paper aims to apply two methods namely, Vortex Method and Higher Order Spectral Method to study the wave breaking and wave interaction. The breaking of shallow water gravity wave is performed using Vortex method, while the interaction between two gravity waves is carried out using Higher Order Spectral (HOS) method. In Vortex method an interface defined by a density or velocity discontinui...

In recent years, the demand for high data rate wireless communications has increased dramatically, which requires larger bandwidth to sustain multi-user accessibility and quality of services. This can be achieved at millimeter wave frequencies. Graphene is a promising material for the development of millimeter-wave electronics because of its outstanding electron transport properties. Up to now,...

Wave switching is a hybrid switching technique for high performance routers. It combines wormhole switching and circuit switching in the same router architecture. Wave switching achieves very high performance by exploiting communication locality. When two nodes are going to communicate frequently, a physical circuit is established between them. By combining circuit switching, pre-established ph...

Tuned Liquid Dampers (TLD) are among passive control devices that have been used to suppress the vibration of structures in recent years. These structures must be adequately presentable as an equivalent single degree of freedom system with long fundamental period. The TLD, located at the top floors of the structure, can dissipate the external input energy into the system through the sloshing ef...

recently testing of quantum-dot cellular automata (qca) circuits has attracted a lot of attention. in this paper, qca is investigated for testable implementations of reversible logic. to amplify testability in reversible qca circuits, a test method regarding to built in self test technique is developed for detecting all simulated defects. a new reversible qca mux 2×1 design is proposed for the ...
