Machine design for Gauge Repeatability and Reproducibility measurement of vision modules

This paper highlights the design of an automated machine to effectively conduct dynamic Gauge Repeatability and Reproducibility (GRR). Design considerations are included when designing a machine dealing with vision systems and methods to increase speed and accuracy is proposed. The outcome is a machine that is able to achieve speeds of up to 1500UPH using a simple design and readily available industrial components.

Abnormal Walking Styles Definition

This paper reports the experimental of human walking style data collection system to know abnormal walking styles. The collection system is composed of 3D accelerator and body area network. Data is stored in a PC for the comparison of the normal and abnormal walking style differences. Based on the differences, we are going to define abnormal walking style in terms of 3D acceleration amplitudes.

An automated approach to generate mixed-dimensional finite element analysis model

Feature-based solid modelling systems has been widely use in product design. Ideally the models generated within these solid modelling systems can be reused in downstream operations, such as finite element analysis. However, for engineering analysis an abstracted model is usually more appropriate, in term of accuracy and efficiency. This paper describes an automated approach to approximate an abstract model through the geometric information provided by medial axis transform (MAT). This approach simplifies the original models by first identifies long and slender regions that can be more efficiently represent by a lower dimension element during finite element analysis. Then partition the models into separate cells using the cellular modelling representation for further processing and mesh generation.
