Abstract The effect of anharmonicity (coupling) in the field theory generally results dissipation plane waves. It has been appreciated that and ensuing waves can be accompanied by emergence gapped momentum state. Here, we show same lead to a energy state dispersion relation where frequency (energy) gap emerges explicitly. We discuss several notable properties states connections between them.

In conventional structural design, the stiffness and energy absorption mechanisms are combined in a single system, and the structure is allowed to deform inelastically. Experience with recent earthquakes has shown that the economical penalty associated with repairing conventionally designed structures can be significant. Situations also exist in which the conventional design approach is not app...

Extreme events are ubiquitous in a wide range of dynamical systems, including turbulent fluid flows, nonlinear waves, large-scale networks, and biological systems. We propose a variational framework for probing conditions that trigger intermittent extreme events in high-dimensional nonlinear dynamical systems. We seek the triggers as the probabilistically feasible solutions of an appropriately ...

Reconfigurable System-on-Chip (RSoC) devices incorporate various components, such as processor core, reconfigurable logic, memory, etc., onto a single chip. They are being used to implement many wireless embedded systems, where energy efficiency is a major concern. When an application is synthesized on RSoCs, part of it can be executed using hardware implementations on the reconfigurable logic ...

Energy dissipation in single asperity sliding friction was directly linked to submolecular modes of mobility by intrinsic friction analysis, involving time-temperature superposition along with thermodynamic stress and reaction rate models. Thereby, polystyrene served as a representative tribological sample for organic and amorphous complex systems. This study reveals the significance of surface...

Energy dissipation is a hot topic in the design of-especially mobile embedded systems. This is because applications like digital video cameras, cellular phones etc. draw their currentfrom batteries that spend a limited amount of energy only. In this paper we show that energy-conscious HW/SWpartitioning can lead to drastic reductions of energy dissipation of a whole embedded system. Subject of i...

In this work we study the following problem: given a numerical method (an extended θ−method named the (θ, γ)-method), find the class of dissipative linear complementarity systems such that their discrete-time counterpart is still dissipative, with the same storage (energy) function, supply rate (reciprocal variables), and dissipation function. Systems with continuous solutions, and with state j...

The indispensable vital structure in any harbor is a breakwater in order to make available calm water region inshore. Pile breakwater can be employed as a small coastal protection structure where tranquility required is low. This study is concerned with CFD study on the performance of perforated hollow pile to dissipate wave energy and the novelty of this investigation is the role of perforatio...

We consider mechanical systems with intermittent contact that are smooth and holonomic except at the instants of transition. Overall such systems can be nonholonomic in that the accessible configuration space can have larger dimension than the instantaneous motions allowed by the constraints. The known examples of such mechanical systems are also dissipative. By virtue of their non-holonomy and...

Laminar two dimensional forced convective heat transfer of Al2O3 –water nanofluid in a horizontal microchannel has been studied numerically, considering axial conduction, viscous dissipation and variable properties effects. The existing criteria in the literature for considering viscous dissipation in energy equation are compared for different cases and the most proper one is applied for the re...
