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 ... -

Demand Driven MRP – The need to standardise an implementation process
(Universitat Politècnica de València, 2020)Since the creation of the demand-driven material requirement planning (DDMRP) model, numerous studies have analysed the methodology’s significant impact on different organisations. Several successful cases and research ... -
Towards the automation of the die spotting process: Contact blue pattern decryption
(Elsevier Ltd., 2020)Automotive die spotting is one of the most complex and least standardized processes in the tool making process. A spotting expert identifies local contact areas through a blue-paste pattern and the die/sheet contact is ... -
Systematic complexity reduction of wave-to-wire models for wave energy system design
(Elsevier Ltd., 2020)Wave-to-wire models are valuable tools for a variety of applications in the development of successful wave energy converters. However, computational requirements of these wave-to-wire models are often prohibitive for certain ... -
Optical Dual Laser Based Sensor Denoising for OnlineMetal Sheet Flatness Measurement Using Hermite Interpolation
(MDPI AG, 2020)Flatness sensors are required for quality control of metal sheets obtained from steel coils by roller leveling and cutting systems. This article presents an innovative system for real-time robust surface estimation of ... -
A Diagnostics Framework for Underground Power Cables Lifetime Estimation Under Uncertainty
(IEEE, 2020)Power cables are critical assets for the reliable operation of the grid. The cable lifetime is generally estimated from the conductor temperature and associated lifetime reduction. However, these tasks are intricate due ... -
Case Study of the Experience Capturer Evaluation Tool in the Design Process of an Industrial HMI
(MDPI AG, 2020)In the absence of user experience evaluation tools for industrial human–machine interfaces (HMI), a specific tool called eXperience Capturer (XC) has been created. It is a multi-method user-centred tool that evaluates the ... -
A review of the effects of cyclic contact loading on fretting fatigue behaviour
(Sage Publishing Ltd., 2020)A damage phenomenon called fretting fatigue frequently takes place when two contact bodies are clamped together under a normal contact load along with a small-scale oscillatory motion due to cyclic loading. In contrast to ... -
