Computational kinematics for robotic manipulators: Jacobian problems

O. Altuzarra, O. Salgado, V. Petuya, A. Hernández

This paper aims to provide tools for the complete Jacobian analysis of robotic manipulators of general topology, using a comprehensive velocity equation.

Combination of body‐fitted and embedded grids for external vehicle aerodynamics

Ralf Tilch, Ali Tabbal, Ming Zhu, Friedhelm Decker, Rainald Löhner

This paper seeks to reduce the time it takes to perform external aerodynamic simulations without compromising accuracy. At present, cleaning up CAD data sets, in…

Fast computation of preloaded bolted circular joint aiming at fatigue bolt sizing: Hypotheses and modeling

Dimitri Leray, Aurelian Vadean, Alain Daidie

This paper seeks to deal with a new modelization method which aims at fatigue sizing of preloaded bolted joints. Industrial design offices indeed need new models which, on…

Graph theoretical implementation of memetic algorithms in structural optimization of frame bracing layouts

A. Kaveh, M. Shahrouzi

The generality of the genetic search in the light of proper coding schemes, together with its non‐gradient‐based search, has made it popular for many discrete problems…

Application of geographic information system to the allocation of disaster shelters via fuzzy models

Chung‐Hung Tsai, Cheng‐Wu Chen, Wei‐Ling Chiang, Meng‐Lung Lin

Fuzzy theory provides a rigorous, flexible approach to the problem of defining and computing. Therefore, to facilitate decision making in a geographic information system…
