    Engineering education through an intercontinental PLM collaborative project: The Global Factory case study
    (Institute of Electrical and Electronics Engineers Inc., 2015-01-01) Mejia-Gutierrez, R.; Carvajal-Arango, R.; Zins, J.
    This article will present the experience in the development of an intercontinental collaborative project named 'Global Factory', being the first massive academic exploration of this new way of engineering work. The main goal of the project, was to collaboratively design a virtual factory to produce vehicle combustion engines, by using the Product Lifecycle Management (PLM) software CATIA V6. It was developed collaboratively by students from different universities around the world with distributed work and a centralized database. Therefore, interdisciplinary work was encouraged, leading students to collaborate with colleagues from different disciplines and countries. Students were subject to real conditions of international work and the implied working conditions (e.g. cultural aspects, time-frames, communication limitations, use of Information and Communication Technologies (ICT), etc.). Furthermore, they had to deal with the natural complexity of the technical work as well as the global interaction aspects, being a complicated task to be developed in a novel tool. Finally, the paper will describe the analysis of the project and the educational aspects that students had to face. This project sets the basis for preparing engineers of the future, who will work in a global environment. © 2014 IEEE.

    Estimation of combustion engine technical state by multidimensional analysis using SVD method
    (Inderscience Enterprises Ltd., 2013-01-01) Martinod, R.M.; Betancur, G.R.; Castañeda, L.F.; Kalaczynski, T.; Zóltowski, M.; Universidad EAFIT. Departamento de Ingeniería Mecánica; Estudios en Mantenimiento (GEMI)
    The changes of vibration estimators as a result of engine maladjustment, waste, damage or failure are the main idea of vibrodiagnostic investigation. Diagnostic investigations that use vibration to determine the technical state of combustion engines are very difficult. A limited set of proposed methods could have use in diagnostics. This paper presents a validation of research results of the use of the singular value decomposition (SVD) method. The research object is a combustion engine with power 55 kW at 830 rpm, which is feasible to obtain signals generated by vibration, as well as investigate the influence of the engine in the variation of the vibroacoustic data. Using the SVD method is possible to decide which symptom in the observation matrix is the best to recognise the technical state of combustion engines. Copyright © 2013 Inderscience Enterprises Ltd.
