Synchronous binary asteroids can experience libration about their tidally-locked equilibrium, which will result in energy dissipation. This is an important topic to the Asteroid Impact and Deflection Assessment, where excitation caused by DART kinetic impact Didymos asteroid system may be reduced through dissipation before Hera arrives survey effects of impact. We develop a numeric model for ex...

The rate of viscous energy dissipation in a shear layer of incompressible Newtonian fluid with injection and suction is studied by means of exact solutions, nonlinear and linearized stability theory, and rigorous upper bounds. The injection and suction rates are maintained constant and equal and this leads to solutions with constant throughput. For strong enough suction, expressed in terms of t...

Power dissipation is rapidly becoming a major design concern for companies in the high-end microprocessor market. The problem now is that designers are reaching the limits of circuit and mechanical techniques for reducing power dissipation. Hence, we must turn our attention to architectural approaches to solving this problem. In this work we propose a method of instruction scheduling which limi...

We develop a theoretical framework that explains the use of amplitude modulation AFM to measure and identify energy dissipation processes at the nanoscale. The variation of the dissipated energy on a surface by a vibrating tip as a function of its amplitude has a shape that singles out the dissipative process. The method is illustrated by calculating the dynamic-dissipation curves for surface a...

The increasingly demanding performance requirements trigger the development of new devices to eliminate the limitations concerning the post-earthquake performance of available seismic protection systems. The prerequisite for economical earthquakeresistant bridges is the structures’ capacity to absorb and dissipate a large amount of seismic energy. A widely considered strategy for enhancing this...

this paper describes experimental and numerical investigations on two specimens of frames composed of steel reinforced concrete beam and angle-steel concrete column under horizontal low cyclic loading. based on the test results, the relationship curves of the horizontal load-displacement and the failure modes are acquired. meanwhile the hysteretic behaviors, skeleton curves, stiffness degradati...

This paper describes the system design of a lowpower wireless camera. A system level approach is used to reduce energy dissipation and maximize battery lifetime. System properties such as the network configuration and data statistics are exploited to minimize computational switching. Embedded power supplies systems are also used to minimize energy dissipation under varying temperature, process ...

We adress the problem of interactions between the longitudinal velocity increment and the energy dissipation rate in fully developed turbulence. The coupling between these two quantities is experimentally investigated by the theory of stochastic Markovian processes. The so–called Markov analysis allows for a precise characterization of the joint statistical properties of velocity increment and ...
