A fast and accurate simulation method for high-speed clock trees with buffer insertions is proposed in this paper, where transmission line model is used in all branches of clock trees rather than only in main path. The proposed method is based on two-moment matching technique and can approximate all damping responses, with analytical formulas for time domain responses given. It is shown that th...
We propose a novel algorithm for stereo matching using a dynamical systems approach. The stereo correspondence problem is first formulated as an energy minimization problem. From the energy function, we derive a system of differential equations describing the corresponding dynamical system of interacting elements, which we solve using numerical integration. Optimization is introduced by means o...
In this work, ab initio parametrization of water force field is used to get insights into the functional form of empirical potentials to properly model the physics underlying dispersion interactions. We exploited the force matching algorithm to fit the interaction forces obtained with dispersion corrected density functional theory based molecular dynamics simulations. We found that the standard...
Including Internal Losses in the Equivalent Circuit Model of the Slac Damped Detuned Structure (dds)
In the equivalent circuit model for the DDS originally presented no losses were explicitly included in the cell circuits or the manifold circuits. Damping via the manifolds was effected by imposing matching conditions (including the possibility of reflection) on the ends of the manifolds. In this paper we extend the circuit theory to include lossy circuit elements. We discuss and compare shunt ...
Mechanical relaxation experiments have been widely applied to bulk high temperature (HT,) superconducting materials. In contrast to that only few results obtained on HT, superconducting thin films were reported. None dealt with stress driven phenomena due to the high background damping from the substrate materials used. In applied magnetic fields, however, a host reed technique can be used and ...
Linear colliders, such as the SLC, are among those accelerators for which a high-yield positron source operating at the repetition rate of the accelerator is desired. The SLC, having electron energies up to 50 GeV, presents the possibility of generating positron bunches with useful charge even exceeding that of the initial electron bunch. The exact positron yield to be obtained depends on the p...
identification of damping parameter is usually more complicated and unreliable comparing to mass or stiffness identification in structural dynamics. there are many factors such as intermolecular friction, coulomb friction and viscous damping affecting the damping mechanisms in a structure. therefore it is difficult, and in some cases impossible, to describe the details of damping mechanisms by ...
In this note, we show how to marginalize over the damping parameter of the PageRank equation so as to obtain a parameter-free version known as TotalRank. Our discussion is meant as a reference and intended to provide a guided tour towards an interesting result that has applications in information retrieval and classification.
In this article we consider an n-dimentional thermoelastic system with a viscoelastic damping localized on a part of the boundary. We establish an explicit and general decay rate result that allows a larger class of relaxation functions and generalizes previous results existing in the literature.
This paper reports a study of multilayer nanolamellar Mo/Nb/TiNi composites designed by the principle martensitic transformation enabled lattice strain matching. The composite was fabricated hot packaged accumulative roll bonding (PARB) and wire drawing. showed an apparent yield strength ~1200 MPa recoverable superelastic ~7%, with mechanical damping ~62 MJ/m3. Both Nb Mo nanolamellae sandwiche...
