Steady-state Measurements of Ternary Mixtures in Thermogravitational Microcolumn Using Optical Digital Interferometry
(Springer Nature B.V., 2021)Steady-state measurements in a thermogravitational microcolumn using optical digital interferometry are presented here for the first time in the literature in the case of ternary mixtures. These measurements enabled the ... -
Investigation of diffusive and optical properties of vapour-air mixtures: The benefits of interferometry
(Elsevier Ltd., 2021)While interferometry has been widely used for diffusion measurements in liquid mixtures, it was hardly applied so far to vapour-gas mixtures. The present work aims to bridge this gap. Using an improved Mach–Zehnder ... -
A Generalization Performance Study Using Deep Learning Networks in Embedded Systems
(MDPI, 2021)Deep learning techniques are being increasingly used in the scientific community as a consequence of the high computational capacity of current systems and the increase in the amount of data available as a result of the ... -
Ball-on-flat linear reciprocating tests: Critical assessment of wear volume determination methods and suggested improvements for ASTM D7755 standard
(Elsevier B.V., 2021)This work presents a critical assessment of wear volume determination methods for ball-on-flat linear reciprocating sliding tribological tests. It revealed that the ASTM D7755-11 standard leads to the highest relative ... -
Assessment and Selection of Technologies for the Sustainable Development of an R&D Center
(MDPI, 2020)The central role of R&D centers in the advancement of technology within industrial enterprises is undeniable and clearly a ects their strategies, their competitiveness and their business sustainability. R&D centers assume ... -
Industrial Design of Electric Machines Supported with Knowledge-Based Engineering Systems
(MDPI, 2021)The demand for electric machines has increased in the last decade, mainly due to applications that try to make a full transition from fuel to electricity. These applications encounter the need for tailor-made electric ... -
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 ... -
FlexRQC: Model for a Flexible Robot-Driven Quality Control Station
(Elsevier Ltd., 2020)As the investment on a dedicated quality control stations is not desirable for limited production batches. In general, those systems result in very optimised systems and the lack of flexibility since they are designed for ... -
Evaluating Disruptive Innovation Project Management Capabilities
(MDPI, 2020)Firms must adapt to a business environment in constant flux. Economic and political factors and the constant interruption of new technologies force firms and organizations to change and to adapt, so that they are not left ... -
Evaluation of a strategy-oriented method to identify and prioritise knowledge management initiatives in SMEs
(OmniaScience, 2021)Purpose: This article presents the process followed for the definition, application and evaluation of a strategy-oriented method for identifying and prioritising knowledge management (KM) initiatives in small to medium-sized ... -
Diffusion of Quinine with Ethanol as a Co-Solvent in Supercritical CO2
(MDPI, 2020)This study aims at contributing to quinine extraction using supercritical CO2 and ethanol as a co-solvent. The diffusion coefficients of quinine in supercritical CO2 are measured using the Taylor dispersion technique when ... -
Partial Power Processing Based Converter for Electric Vehicle Fast Charging Stations
(MDPI, 2021)This paper focuses on the design of a charging unit for an electric vehicle fast charging station. With this purpose, in first place, different solutions that exist for fast charging stations are described through a brief ... -
In-SEM micro-machining reveals the origins of the size effect in the cutting energy
(Springer Nature, 2021)High-precision metal cutting is increasingly relevant in advanced applications. Such precision normally requires a cutting feed in the micron or even sub-micron dimension scale, which raises questions about applicability ... -
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 ... -
Economic evaluation of supplementing the diet with 1 Souvenaid in patients with prodromal Alzheimer's disease
(BioMed Central Ltd. Part of Springer Nature, 2020)Background: The LipiDiDiet trial showed that Souvenaid, a medical food, might delay progression to dementia in prodromal Alzheimer’s disease (AD). The objective of this study was to assess the cost-utility of Souvenaid ... -
Framework to evaluate continuous improvement process efficacy: a case study of a capital goods company
(2020)Purpose: This document describes a continuous improvement process assessment system (CIPAS). A continuous improvement process (CIP) was developed to progress through the levels of continuous improvement (CI) defined by ... -
A methodology and experimental implementation for industrial robot health assessment via torque signature analysis
(MDPI AG, 2020)This manuscript focuses on methodological and technological advances in the field of health assessment and predictive maintenance for industrial robots. We propose a non-intrusive methodology for industrial robot joint ... -
Analysis and Design Guidelines for Current Control Loops of Grid-Connected Converters Based on Mathematical Models
(MDPI AG, 2020)Having a method for analyzing and designing regulators of controls that contain many current loops such as active filters is not a trivial task. There can be many parameters of regulators and filters that must be carefully ... -
