Definición de una metodología optimizada para la simulación del desgaste en materiales
(Consejo Superior de Investigaciones Científicas (CSIC), 2010)The wear simulation with finite element method (FEM) presents great advantages for the improvement of components, because of the reduction in the cost in comparison to the experimental procedure (test time, materials, ... -
Factor graph based detection approach for high-mobility OFDM systems with large FFT modes
(Springer, 2012)In this article, a novel detector design is proposed for orthogonal frequency division multiplexing (OFDM) systems over frequency selective and time varying channels. Namely, we focus on systems with large OFDM symbol ... -
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 ... -
Simulation of distortion due to machining of thin-walled components
(Elsevier, 2013)The distortion of components is strongly related to the residual stress state induced by manufacturing processes like heat treatment, forming or machining. Each process step affects the initial stress state of the following ... -
A sensibility analysis to geometric and cutting conditions using the particle finite element method (PFEM)
(Elsevier, 2013)The (PFEM) is employed to simulate orthogonal metal cutting of 42CD4 steel. The objectives of this work are mainly three: The first one is to validate PFEM strategies as an efficient tool for numerical simulation of metal ... -
Evolution of residual stresses induced by machining in a Nickel based alloy under static loading at room temperature
(Elsevier, 2014)Tensile residual stresses are very often generated on the surface when machining nickel alloys. In order to determine their influence on the final mechanical behaviour of the component residual stress stability should be ... -
Finite Element Prediction of the Tool Wear Influence in Ti6Al4V Machining
(Elsevier, 2015)Ti6Al4 V is a titanium alloy widely used in the aeronautical industry and machining is often adopted to manufacture it. These parts must satisfy requirements specified by the customer. A crucial characteristic of aircraft ... -
Numerical Simulation of Surface Modification During Machining of Nickel-based Superalloy
(Elsevier, 2015)The main objective of this study is to implement a reliable FE model of the orthogonal machining of a Nickel based superalloy for the prediction of microstructural changes occurring during the process. A FE numerical model ... -
Influencia del agua de mar en el comportamiento frente a impacto de baja energía de un nuevo laminado de resina natural reforzada con fibra de fique colombiano
(Universidad Nacional de Colombia, 2015)This experimental work is aimed at the influence of seawater immersion in low impact energy behavior of a novel Colombian fique fiber reinforced bio-resin laminate. Such material was manufactured by vacuum infusion. The ... -
An all-in-one numerical methodology for fretting wear and fatigue life assessment
(Gruppo Italiano Frattura, 2016)Many mechanical components such as, bearing housings, flexible couplings and spines or orthopedic devices are simultaneously subjected to a fretting wear and fatigue damage. For this reason, the combined study on a single ... -
Three stage maturity model in SME's towards Industry 4.0
(Universitat Politecnica de Catalunya, 2016)Purpose: To address the challenges regarding the concept of Industry 4.0 and the diversification methodology and based on the strategic guidance towards Industry 4.0, we propose a process model as a guiding framework for ... -
Closing the Brand Gap through innovation and design
(Elsevier B.V., 2016)Existing brands already have certain products and services that generate a particular experience in the mindof custome.However, distortions exist between what the brands what to communicate and ... -
Machine Learning Techniques for the Detection of Shockable Rhythms in Automated External Defibrillators
(PLOS, 2016)Early recognition of ventricular fibrillation (VF) and electrical therapy are key for the survivalof out-of-hospital cardiac arrest (OHCA) patients treated with automated external defibrilla-tors (AED). AED algorithms for ... -

Project-based collaborative engineering learning to develop Industry 4.0 skills within a PLM framework
(Elsevier B.V., 2017)Training and learning methods for engineering students, in the disciplines of product design and manufacturing, are becoming more difficult and complex since they have to integrate theoretical technical knowledge, skills ... -
Towards Large-Scale, Heterogeneous Anomaly Detection Systems in Industrial Networks: A Survey of Current Trends
(The Wiley Hindawi Partnership, 2017)Industrial Networks (INs) are widespread environments where heterogeneous devices collaborate to control and monitor physical processes. Some of the controlled processes belong to Critical Infrastructures (CIs), and, as ... -
Equivalence of primary control strategies for AC and DC microgrids
(MDPI, 2017)Microgrid frequency and voltage regulation is a challenging task, as classical generators with rotational inertia are usually replaced by converter-interfaced systems that inherently do not provide any inertial response. ... -
Thermodiffusion in multicomponent n-alkane mixtures
(Nature Research (Part of Springer Nature), 2017)Compositional grading within a mixture has a strong impact on the evaluation of the pre-exploitation distribution of hydrocarbons in underground layers and sediments. Thermodiffusion, which leads to a partial diffusive ... -
U-drawing of Fortiform 1050 third generation steels. Numerical and experimental results
(IOP Publishing Ltd, 2017)Elasto–plastic behavior of the third generation Fortiform 1050 steel has been analysed using cyclic tension–compression tests. At the same time, the pseudo elastic modulus evolution with plastic strain was analysed using ...
