We present an integrated system to automatically generate computer-aided design (CAD) models of existing vehicle parts using laser range imaging techniques. The proposed system integrates data acquisition, model reconstruction, and post processing to generate a set of models from real-world automotive parts. This range image-based, computer-aided reverse engineering (CARE) system has potential ...

In this paper, we explore the technical challenges to automatically generate computer-aided design models of existing vehicle parts using laser range imaging techniques. We propose a complete system that integrates data acquisition and model reconstruction. We discuss methods to resolve the occlusion problem and the associated registration problem. We also present our reconstruction algorithm. ...

introduction breast cancer is the second cause of mortality among women. early detection of it can enhance the chance of survival. screening systems such as mammography cannot perfectly differentiate between patients and healthy individuals. computer-aided diagnosis can help physicians make a more accurate diagnosis. materials and methods regarding the importance of separating normal and abnorm...

This paper presents concepts for computer aided support of engineering processes. We briefly discuss the basic tenets of the engineering enterprise and fundamental design and analysis techniques. Then, process modeling definitions are given and extended to encompass engineering process capture. An architecture is introduced that comprises executive, coordination, and execution layers, intended ...

A new algorithm for approximation of a given surface or scattered points by a surface of revolution is presented. It forms the basis for a study of approximation with profile surfaces. Those are sweeping surfaces traced out by a planar curve when its plane is rolling on a developable surface. Important special cases include developable surfaces and pipe surfaces, where the moving curve is a str...

New methods for e-learning and research are growing up in the field of chemical engineering, as computer aided tools become more important. Concepts as distributed laboratories for education and research, associated to the e-learning and lifelong learning tasks, have been implemented in specific applications at the Faculty of Chemistry and Chemical Engineering of “Babes-Bolyai” University. Appl...
