Compliant actuator technology aims at building robots capable of physically interacting with humans and the environment, matching versatility capacity biological systems. Recently, it underwent a significant evolution introduction damping to improve performance. Such development reflects several aspects, including energy saving oscillation mitigation. However, large values tend increase system ...

In the current study the influence of weight percentage of HIPS, weight percentage of CNT and hardener content on damping 1st and damping 2nd properties of epoxy/HIPS/CNT hybrid composite wase valuated. Mixture design methodology was employed to generate mathematical models for predicting damping 1st and damping 2nd behaviors of new mentioned hybrid nanocomposite as function of physical factors...

Electron trapping in a finite amplitude Langmuir wave (LW) leads to a frequency shift, ∆ωTP < 0 , and reduced Landau damping. These may lead to modulational instability. Its growth rate and damping threshold, due to escape of trapped electrons at rate ν, are calculated for the first time in the short wavelength regime. If the background plasma is in thermal equilibrium, it is shown that this tr...

A common type of matching problem involves finding the strengths for four (4) quadrupoles in a transfer line, that will transport a particular beam at the entrance, to produce a beam at the exit of the line with a specified set of horizontal and vertical Twiss parameters. A number of optics programs may be used to find a solution to this type of problem, but the quadrupole strengths obtained ar...

in the present paper the behavior of an elastically mounted cylinder in low and high mass-damping ratio is investigated. for high mass-damping ratio, a classical wake oscillator model is used. at the first, by neglecting all damping and nonlinear terms of this model, the possibility of using a linear model for determination of the lock-in range and the dominant mode is investigated. then, witho...

ontology is the main infrastructure of the semantic web which provides facilities for integration, searching and sharing of information on the web. development of ontologies as the basis of semantic web and their heterogeneities have led to the existence of ontology matching. by emerging large-scale ontologies in real domain, the ontology matching systems faced with some problem like memory con...

The Stanford Linear Collider was designed to operate with round beams [ 11; horizontal and vertical emittance made equal hi the damping rings. The main motivation was to facilitate the optical matching through beam lines with strong coupling elements like the solenoid spin rotator magnets and the SLC ales. Tests in 1992 showed that ‘flat’ beams with a vertical to horizontal emittance ratio of a...

We study the relation between PageRank and other parameters of information networks such as in-degree, out-degree, and the fraction of dangling nodes. We model this relation through a stochastic equation inspired by the original definition of PageRank. Further, we use the theory of regular variation to prove that PageRank and in-degree follow power laws with the same exponent. The difference be...

We present a four-body semileptonic charm decay D → Kπμν analysis in the range of 0.65 GeV/c < mKπ < 1.5 GeV/c . We observe a low mass scalar contribution of 5.30 ± 0.74 0.99 − 0.96% with respect to the total D →Kπμν decay, compatible with the phase shift found by the LASS elastic scattering experiment. For the K(892) resonance, we obtain a mass of 895.41 ± 0.32 − 0.43 MeV/c , a width of 47.79 ...
