[1] Earthquake nucleation and early seismic propagation are studied in a two-dimensional strike-slip fault model with depth-variable properties. The fault is governed by the Dieterich-Ruina rate and state friction law. We use an efficient and rigorous numerical procedure for elastodynamic analysis of earthquake sequences on slowly loaded faults developed by Lapusta et al. [2000]. We find that f...

for finding the optimal choices of applied remote loads – normal force, moment, shear force and bulk stresses needed to solve frictional contact problems in partial-slip using half-plane theory are derived by data from contacts analysed finite element method. While forces moment readily found equilibrium considerations, order determine we must exploit details traction ratio direct strain within...

The doubly-fed induction generator (DFIG) is widely used in variable speed wind energy conversion systems (WECS). This paper presents a review on various topologies, configuration, power converters and control schemes used with the operation of the DFIG. The operation of DFIG based on both slip ring and brushless arrangement has been discussed. The grid integration of DFIG and its influence on ...

This paper describes an experiment eliciting spoonerisms by using the so-called SLIP technique. The purpose of the experiment was to provide a further test of the hypothesis that self-monitoring of inner speech is a major source of lexical bias ([1; 10; 11; 14]. This is a follow-up on an earlier experiment in which subjects were explicitly prompted after each response to make a correction in ca...

In recent years, there has been considerable interest in investigating the effects of fretting, a common problem of significant practical importance that can affect a wide range of electrical equipment incurring costly component replacement and expensive equipment downtime. Fretting is defined as accelerated surface damage occurring at the interface of contacting materials subjected to small os...

because of its kinetic nature and computational advantages, the lattice boltzmann method (lbm) has been well accepted as a useful tool to simulate micro-scale flows. the slip boundary model plays a crucial role in the accuracy of solutions for micro-channel flow simulations. the most used slip boundary condition is the maxwell slip model. the results of maxwell slip model are affected by the ac...

An efficient and accurate algorithm for solving the two-dimensional (2D) incompressible Navier–Stokes equations on a disk with no-slip boundary conditions is described. The vorticitystream function formulation of these equations is used, and spatially the vorticity and stream functions are expressed as Fourier–Chebyshev expansions. The Poisson and Helmholtz equations which arise from the implic...

We have performed multimillion-atom molecular dynamics simulations of nanoindentation on cubic silicon carbide !3C-SiC" surfaces corresponding to three different crystallographic directions, !110", !001", and !111", using pyramidal-shaped Vickers indenter with 90° edge angle. Load-displacement !P-h" curves show major and minor pop-in events during loading. Detailed analysis of the !110" indenta...

Simple methods of finding the transient and steady state stick zones for frictional contacts subject to varying normal shear forces are discussed. Particular emphasis is given Hertzian contact because algebra very simple this geometry, but results may be carried over any other geometry that can solved within framework half plane theory, including widely-occurring flat with radiused edges.
