Modern Project Management Approaches in Uncertainty Environments: A Comparative Study Based on Action Research
(MDPI, 2020)Change and high uncertainty levels are the main characteristics of current project contexts. Years ago, the traditional project management faced problems when operating in these environments. Thus, at the end of the 20th ... -
Monitoring of a Hammer Forging Testing Machine for High-Speed Material Characterization
(Elsevier Ltd., 2020)Dynamic testing of materials is necessary to model high-speed forming processes (i.e. hammer forging, blanking) and crash/impact behavior of structures, among others. The most common machines to perform medium to high-speed ... -
A Multi Camera and Multi Laser Calibration Method for 3D Reconstruction of Revolution Parts
(MDPI, 2021)This paper describes a method for calibrating multi camera and multi laser 3D triangulation systems, particularly for those using Scheimpflug adapters. Under this configuration, the focus plane of the camera is located at ... -
Multi revolution finite element model to predict machining induced residual stresses in Inconel 718
(Elsevier, 2013)Inconel 718 is commonly used in structural critical components of aircraft engines due to its mechanical thermal properties at high temperatures, which makes it to be considered as a difficult to machine material. In these ... -
Multi-Physics Tool for Electrical Machine Sizing
(MDPI AG, 2020)Society is turning to electrification to reduce air pollution, increasing electric machine demand. For industrial mass production, a detailed design of one machine is usually done first, then a design of similar machines, ... -
A Multicriteria Decision Model for the Evaluation and Selection of Technologies in a R&D Centre
(Universitat Politècnica de València, 2019)R&D Centres play a key role in the technology development process of industries, and therefore in their competitive strategies. They have responsibility in the identification, selection, acquisition, development and transfer ... -
Near Solidus Forming (NSF): Semi-Solid Steel Forming at High Solid Content to Obtain As-Forged Properties
(MDPI AG, 2020)Near solidus forming (NSF) of steels is a novel process under the umbrella of semi-solid forming technologies midway between classical hot forging and semi-solid technologies. This article presents the work done at Mondragon ... -
Necesidades a Futuro y Situación Actual de las Competencias en Educación Superior en el Contexto de España
