This work presents a commentary of the article published by A. Zadegan and A. Zilouchian (ASME J. Dyn. Sys. Meas. Contr. ,Volume 127,Issue 3, pp. 486-498, 2005). We show their order reduction method is not always true and may leads to inaccurate results and is therefore erroneous. A framework for solving the problem is also suggested .

The main objective of the proposed research is to improve various stability and handling qualities (such as Roll Over stability, Lane Change maneuver stability etc) of military, off road, unmanned multi-body ground vehicles within as wide operating envelope as possible under the presence of uncertainty in vehicle model parameters as well as under various sensor, actuator and component faults. A...

The development of products with a modular structure, where the constituent modules could be derived from a set of common platforms to suit different market niches, provides unique engineering and economic advantages. However, the quantitative design of such modular product platforms could become significantly challenging for complex products. The Comprehensive Product Platform Planning (CP3) m...

Virtual manufacturing systems carry out the simulation of manufacturing processes in digital environment in order to increase accuracy as well as productivity in part production. There are different error sources in machine tools such as tool deflection, geometrical deviations of moving axis and thermal distortions of machine tool structures. The errors due to tool deflection is caused by cutti...

Convective heat transfer of laminar, single-phase flow in rough microtubes is studied. Wall roughness and slope are assumed to possess Gaussian, isotropic distributions. Fractal concepts are used to model the rough microtube. It is shown that due to the existence of wall roughness, both cross-sectional and inside surface areas are increased. A new concept is defined as a figure of merit for ass...
