Physical gages permit verification with low uncertainties but remain expensive and inflexible. With the development of 3D CAD modellers and the progress made in coordinate measuring machines, the concept of the virtual gage appeared. The paper focuses on the implementation rather than the inspection of dimensional and geometrical tolerancing in 3D-CAD models of mechanical assemblies by the use ...

The inherent massive parallelism of self-assembly is one of its most appealing attributes for autonomous construction. One challenge in parallel self-assembly is to reduce the number of incompatible substructures that can occur in order to increase the yield in target structures. Early studies demonstrated how a simple approach to component design led components to self-assemble into incompatib...

Desiccant wheels are widely used in buildings to control humidity and reduce energy consumption. A model is presented based on transient coupled heat and mass transfer, to model, design and analyze the effects of geometrical characteristics of a honeycombed rotary desiccant wheel and its performance. Governing equations are solved numerically using finite volume method and the model is validate...

Predicting the effective elastic properties of carbon nanotube-reinforced nanocomposites is of great interest to many structural designers and engineers for improving material and configuration design in recent years. In this paper, a finite element model of a CNT composite has been developed using the Representative volume element (RVE) to evaluate the effective material properties of nanocomp...
