We present an efficient dynamic data structure that supports geodesic nearest neighbor queries for a set S of point sites in a static simple polygon P . Our data structure allows us to insert a new site in S, delete a site from S, and ask for the site in S closest to an arbitrary query point q ∈ P . All distances are measured using the geodesic distance, that is, the length of the shortest path...

this research aimed to examine the effect of sequential stimuli technique on acquisition, retention and transfer of ocular motor sequence. first sequential stimuli, time record, response error software was designed. 60 right-handed novices (15-18 years) were divided into five groups (blocked – explicit, blocked – implicit, random – explicit, random-implicit and control). all groups performed a ...

A new method for structural topology optimization is introduced which employs the Isogeometric Analysis (IA) method. In this approach, an implicit function is constructed over the whole domain by Non-Uniform Rational B-Spline (NURBS) basis functions which are also used for creating the geometry and the surface of solution of the elasticity problem. Inspiration of the level set method zero level...

A relaxation system for the incompressible and compressible Euler and Navier-Stokes equations is considered. A numerical scheme working uniformly in the above limits is constructed using higher-order nonoscillatory upwind discretiaations and higher-order implicit-explicit t ime discretization. Numerical results are presented for several test cases. @ 2003 Elsevier Ltd. All rights reserved. Keyw...

Introduction: The electromagnetic gyrokinetic (GK) plasma simulation [1] for toroidal magnetic fusion devices has become a standard tool for turbulence analysis. Recently, it has been recognized that transport involving dynamic changes in profiles requires modelling with full f GK methods [2]. In the present work, we report on transport simulations for the FT-2 tokamak plasma with a full f nonl...

abstract in the dynamic and competitive market, managers seek to find effective strategies for new products development. since there has not been a thorough research in this field, this study is based on a review on the risks exist in the npd process and an analysis of risks through fmea approach to prioritize the existent risks and a modeling behavior of the npd process and main risks using sy...

in this paper, the non-linear dynamic response of novel steel sandwich panel with hollow i-core subjected to blast loading was studied. special emphasis is placed on the evaluation of midpoint displacements and energy dissipation of the models. several parameters such as boundary conditions, strain rate, mesh dependency and asymmetrical loading are considered in this study. the material and geo...

This work presents a Differential Dynamic Programming (DDP) approach for systems characterized by implicit dynamics using sensitivity analysis, such as those modelled via inverse dynamics, variational, and integrators. It leads to more general formulation of DDP, enabling the use faster recursive Newton-Euler dynamics. We leverage precise exact contact modelling in where we focus on two contrib...

a new two-step implicit linear obrechkoff twelfth algebraic order method with vanished phase-lag and its first, second, third and fourth derivatives is constructed in this paper. the purpose of this paper is to develop an efficient algorithm for the approximate solution of the one-dimensional radial schrodinger equation and related problems. this algorithm belongs in the category of the multist...
