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 ... -
Reusability and Flexibility in Parametric Surface-based Models: A Review of Modelling Strategies
(Taylor and Francis Ltd., 2021)CAD systems are indispensable tools in the product design and development process. Through the creation of parametric 3D models,they increase productivity, enable the design of highly complex parts, improve ... -
Retinal thickness predicts the risk of cognitive decline in Parkinson's disease
(Wiley, 2020)Objective: To analyze longitudinal changes of retinal thickness and their predictive value as biomarkers of disease progression in idiopathic Parkinson’s disease (iPD). Methods: Patients with Lewy body diseases (LBDs) ... -
A coupled 3D wear and fatigue numerical procedure: Application to fretting problems in ultra-high strength steel wires
(Elsevier Ltd., 2021)This work presents a coupled 3D wear and fatigue numerical procedure for fretting problems in ultra-high strength steel wires that combines Archard’s wear equation with the Smith–Watson–Topper parameter to predict crack ... -
Preliminary Study on the Capability of the Novel Near Solidus Forming (NSF) Technology to Manufacture Complex Steel Components
(MDPI AG, 2020)The benefits of the novel Near Solidus Forming (NSF) process has shown previously in its ability to produce steel components with comparable as-forged mechanical properties but with a cost reduction of 10–15%. This study ... -
Power Capability Boundaries for an Inverter Providing Multiple Grid Support Services
(MDPI AG, 2020)It is getting more common every day to install inverters that o er several grid support services in parallel. As these services are provided, a simultaneous need arises to know the combined limit of the inverter for those ... -
Stability analysis under thermogravitational effect
(Elsevier Masson SAS, 2020)In the present work, an interferometric unsteady analysis of the thermogravitational technique was for the first time attempted in a paralelepipedic microcolumn using binary mixtures with negative Soret coefficients. In ... -
Efficient Calculation of Stabilization Parameters in RF Power Amplifiers
(IEEE, 2020)This paper proposes an efficient method for the calculation of the stabilization parameters in RF power amplifiers operating in periodic large-signal regimes. Stabilization is achieved by applying the principles of linear ... -
A Strategic Approach for Bottleneck Identification in Make-To-Order Environments: A Drum-Buffer-Rope Action Research Based Case Study
(OmniaScience, 2020)Purpose: This study focused on providing a strategic perspective for the selection and exploitation of bottlenecks in make-to-order production systems, a largely unexplored field in the literature. The researchers developed ... -
An Analysis of the Spanish Universities' Entrepreneurial Activities through Secondary Data (Websites and Reports)
(Allied Business Academies, 2020)Over the past few years, there has been a growing number of studies indicating that entrepreneurial activities performed at universities, such as cooperative research and the creation of spin-offs or patents and licenses, ... -
Effect of Boron Content and Cooling Rate on the Microstructure and Boride Formation of β-Solidifying γ-TiAl TNM Alloy
(MDPI AG, 2020)Boron is a unique and popular grain refiner element in cast titanium aluminide (TiAl) alloys, as it helps to improve mechanical properties if properly alloyed. However, the formation mechanism of different types of borides ... -
A novel forming technique to coforge bimetal components into complex geometries
(Elsevier Ltd., 2020)The novel Near Solidus Forming process has been used to coforge stainless steel 304 to encapsulate a core of 42CrMo4 steel in Stainless 304 in the form of a complex spindle. The forging was achieved with a force of 280 t, ... -
Thermophoresis as a technique for separation of nanoparticle species in microfluidic devices
(Elsevier Masson SAS, 2020)This paper presents numerical studies of thermophoresis approach for separation of nanoparticles in liquid media. We simulated the thermophoresis process to test it as a method of separation of particles in suspension. At ... -
Does employee participation matter? An empirical study on the effects of participation on well-being and organizational performance
(Springer-Verlag GmbH, 2020)Employability, talent and/or motivation of people can be a source of sustainable competitive advantage; difficult for competitors to imitate. The involvement of people, and more specifically employee participation, has ... -
An analytical approach to calculate stress concentration factors of machined surfaces
(Elsevier Ltd., 2021)Machining operations affect the properties of the final surface layer, and these can impact on its functional per- formance, particularly on fatigue behaviour. Among the properties of the machined surface, surface topography ... -
Surface Integrity When Machining Inconel 718 Using Conventional Lubrication and Carbon Dioxide Coolant
(Elsevier Ltd., 2020)Surface integrity induced by machining process affects strongly the performance of functional products, for instance, the fatigue life as well as the resistance to stress corrosion cracking. Consequently, it is relevant ...
