A Performance Study of a Horizontal-axis Micro-turbine in a Numerical Wave Flume

Tutar, Mustafa (Elsevier Ltd., 2017)

Numerical studies of performance of a 3-bladed Savonius type horizontal-axis wave energy converter are presented. Numerical simulations based on a volume of fluid (VOF) method coupled with a finite volume method (FVM) ...

Petri net-based semi-compiled code generation for programmable logic controllers

Azkarate, Igor; Mugarza Cortabarria, Juan Carlos; Eciolaza, Luka (MDPI, 2021)

Industrial discrete event dynamic systems (DEDSs) are commonly modeled by means of Petri nets (PNs). PNs have the capability to model behaviors such as concurrency, synchronization, and resource sharing, compared to a step ...

A population-specific material model for sagittal craniosynostosis to predict surgical shape outcomes

Rodriguez Florez, Naiara (Springer Nature, 2020)

Sagittal craniosynostosis consists of premature fusion (ossification) of the sagittal suture during infancy, resulting in head deformity and brain growth restriction. Spring-assisted cranioplasty (SAC) entails skull incisions ...

The Positive Loop at Work: A Longitudinal Long-Term Study of Transformational Leadership, Group Passion, and Employee Result

Garmendia, Alaine (Frontiers Media S.A., 2021)

Positive psychology and positive organizational behavior studies recognize that leadership is extremely important for generating positive well-being. Despite the frequently reported significant positive correlations, the ...

Llavori, Inigo; Zabala, Alaitz (Elsevier Ltd., 2018)

Power Balancing in Cascaded H-Bridge and Modular Multilevel Converters Under Unbalanced Operation: A Review

Marzo Elguero, Iosu; Barrena, Jon Andoni; Abad, Gonzalo; Muguruza, Ignacio (IEEE, 2021)

Multilevel Voltage-Source Converters (VSC) based on modular structures are envisioned as a prominent alternative for grid and industry applications. Foremost among these are the Cascaded H-Bridge (CHB) and the Modular ...

Power Capability Boundaries for an Inverter Providing Multiple Grid Support Services

Unamuno, Eneko; Bilbao Ortega, Aitor (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 ...

Preliminary Study on the Capability of the Novel Near Solidus Forming (NSF) Technology to Manufacture Complex Steel Components

Plata Redondo, Gorka; Sánchez Fernández, Andrea; Lozares, Jokin; Hurtado Hurtado, Iñaki (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 ...

Press hardening of alternative materials: conventional high- strength steels

Mendiguren, Joseba; Herrero Dorca, Nuria; GALDOS, Lander; Saénz de Argandoña Fernández de Gorostiza, Eneko (Springer Nature, 2017)

he increase in strength of new high strength steels(HHS) and advanced high strength steels (AHHS) has led toforming issues, such as high springback, low formability, increase of forming forces and tool wear. These problems ...

Project-based collaborative engineering learning to develop Industry 4.0 skills within a PLM framework

Ugarte Barrena, Done (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 ...
