چکیده
Linear elastic boundary element models are commonly used tools to understand the mechanics of earthquake cycle processes and their contribution growth tectonic structures. Here we describe a two-dimensional plane strain linear approach based on displacement discontinuity method. This integrates an analytic solution for coincident interactions using three node quadratic elements classic particular integral uni-directional gravity. Three more accurate than classical constant enable exact representation displacements, stresses tractions subject slip gradients. We demonstrate recovery solutions illustrate combined effects faulting gravitational body forces in presence topographic relief. • Analytic provide improved near-field accuracy. A BEM formulation faulting, topography, 2D implementation is provided Julia.

A Quadratic Programming Approach to Quasi-Static Whole-Body Manipulation
This paper introduces a local motion planning method for robotic systems with manipulating limbs, moving bases (legged or wheeled), and stance stability constraints arising from the presence of gravity. We formulate the problem of selecting local motions as a linearly constrained quadratic program (QP), that can be solved efficiently. The solution to this QP is a tuple of locally optimal joint ...

the aim of this study has been to find answers for the following questions: 1. what is the effect of immediate correction on students pronunciation errors? 2. what would be the effect of teaching the more rgular patterns of english pronunciation? 3. is there any significant difference between the two methods of dealing with pronuciation errore, i. e., correction and the teaching of the regular ...
