On the impact of long-term wave trends on the geometry optimisation of oscillating water column wave energy converters
(Elsevier Ltd., 2020)
Wave trends have been shown to be relevant to energy generation in various areas of the world. Accordingly, this article describes the impact of wave trends on the design of oscillating water column wave energy converters. ...
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 ...
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 ...
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 ...
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 ...
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 ...
On the Role of Contact and System Stiffness in the Measurement of Principal Variables in Fretting Wear Testing
(MDPI AG, 2020)
In this work, the role of the contact stiffness in the measurement of principal variables in fretting wear tests is assessed. Several fretting wear tribometers found in the literature, including one developed by the authors, ...
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 ...
Better to Be Alone than in Bad Company: Cognate Synonyms Impair Word Learning
(MDPI, 2020-07-29)
The effects of cognate synonymy in L2 word learning are explored. Participants learned
the names of well-known concrete concepts in a new fictional language following a picture-word
association paradigm. Half of the ...
