A Geometric Tolerancing Method Applicable to a Feature with Multiple Faces.

a comparison of teachers and supervisors, with respect to teacher efficacy and reflection

supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...

Issues in the Metrology of Geometric Tolerancing

The classiication problem is fundamental in the metrology of Geometric Tolerancing: given a part B, is it within some tolerance ? The \standard method-ology" for the classiication problem comprises three steps: sampling , algorithmic step and policy decision . The issues we examine are posed around this methodology, using a simple 1-dimensional problem as case study.

A statistical framework for geometric tolerancing manufactured parts

An image is never noise free. Visual inspection of a part from its image is therefore affected by image errors. Understanding how image errors affect measurement precision is therefore critical for accurate inspection. In this paper, we lay out a statistical framework that allows to explicitly handle image errors and characterize their impact on measurement precision. A hierarchical model is al...

A Geometric Data Structure Applicable to Image Mining and Retrieval

Due to improvements in image acquisition and storage technology, terabyte-sized databases of images are nowadays common. This abundance of data leads us to two basic problems: how to exploit images (image mining)? Or how to make it accessible to human beings (image retrieval)? The specificity of image mining/retrieval among other similar topics (object recognition, machine vision, computer visi...
