abstract for seismic design, it is important to estimate the, maximum lateral displacement (inelastic displacement) of the structures due to earthquakes for several reasons. seismic design provisions estimate the maximum roof and storey drifts occurring in major earthquakes by amplifying the roof displacement and drifts of the structures obtained by elastic analysis subjected to seismic design ...

The nature of the momentum transport processes responsible for the Reynolds shear stress is investigated using several ensembles of fluid particle paths obtained from a direct numerical simulation of turbulent channel flow. It is found that the Reynolds stress can be viewed as arising from two fundamentally different mechanisms. The more significant entails transport in the manner described by ...

We present an improved self-localization estimation algorithm in this paper. The algorithm uses a modified SURF method to extract the interest points, using it to extract the orientation and a descriptor of the interest point in order to lessen the computation time. A robot using this method can estimate its indoor self-localization according to matched interest points. A number of intermediate...

Analysis for the generalized thermoelastic Lamb waves, which propagates in anisotropic thin plates in generalized thermoelasticity, is presented employing normal mode expansion method. The displacement and temperature fields are expressed by a summation of the symmetric and antisymmetric thermoelastic modes in the surface thermal stresses and thermal gradient free orthotropic plate, therefore t...

As a discontinuous Galerkin FEM, we propose a formulation based on Tong’s hybrid displacement method and the stabilization technique, and develop polygonal elements for linear static plane stress problems. The basic ideas are the introduction of inter-element displacements and the use of stabilization terms. Here we only present polygonal elements with polynomial approximation functions. That i...

[1] We perform two-dimensional dynamic models of strike-slip faults with a change in strike (a bend) over multiple earthquake cycles to examine the long-term effects of nonplanar fault geometry. A viscoelastic model (a proxy for off-fault deformation and tectonic loading) is introduced for the interseismic process to avoid pathological stress buildup around the bend. A finite element method wit...

2014 A review is given on the use of diffuse X-ray scattering for the determination of point defect structures in crystalline solids. Diffuse scattering yields a direct method for obtaining detailed information on the displacement fields both near to and far away from the defects in addition to information on the particular position of the defect. Theoretical models involving the use of lattice...

computer model of the patellofemoral joint was developed and the effects on the anterior displacement of the tibial tuberosity were investigated. the input geometrical and verification data for the model were obtained form an experimental study on a cadaver knee, mounted in an instron machine. the computer program found the configuration of the patellofemoral joint which satified both the geome...

The patch-clamp technique allows currents to be recorded through single ion channels in patches of cell membrane in the tips of glass pipettes. When recording, voltage is typically applied across the membrane patch to drive ions through open channels and to probe the voltage-sensitivity of channel activity. In this study, we used video microscopy and single-channel recording to show that prolon...
