Vanadium Redox Flow Batteries: A Review Oriented to Fluid-Dynamic Optimization
(MDPI, 2020-12-31)
Large-scale energy storage systems (ESS) are nowadays growing in popularity due to the increase in the energy production by renewable energy sources, which in general have a random intermittent nature. Currently, several ...
Delamination Fracture Behavior of Unidirectional Carbon Reinforced Composites Applied to Wind Turbine Blades
(MDPI, 2021-01-27)
One of the materials that is used widely for wind turbine blade manufacturing are fiber-reinforced composites. Although glass fiber reinforcement is the most used in wind turbine blades, the use of carbon fiber allows ...
Computational Methods for Modelling and Optimization of Flow Control Devices
(MDPI, 2020-07-19)
Over the last few years, the advances in size and weight for wind turbines have led to the development of flow control devices. The current work presents an innovative method to model flow control devices based on a cell-set ...
Quartzite Procurement in Conglomerates and Deposits: Geoarchaeological Characterization of Potential Catchment Areas in the Central Part of the Cantabrian Region, Spain
(Wiley, 2021-05)
Raw material characterization in Paleolithic archaeology has widened our knowledge of Middle Paleolithic societies. Procurement of raw material, specifically flint, has allowed the tracing of the mobility of both stones ...
A Great Step Forward. Lithic Raw Material Procurement and Management among Palaeolithic Hunter -Gatherers in the Basque Crossroads
(School of History, Classics and Archaeology, University of Edinburgh, 2020)
This paper is divided into three sections. The first section describes the historiographic evolution of the study of prehistoric lithic raw materials in the Basque Crossroads (in the north of the Iberian Peninsula) during ...
Lost in the quest for flint: a gravettian hunting camp (Usategi, Basque Country)
(Wiley, 2021-11)
[EN]Five decades ago, Usategi Cave (Basque Country) yielded a small Gravettian series that included an Isturitz-type bone point. This paper presents the first C-14 dates for the assemblage and new data obtained by the study ...
Shaping Up Zn-Doped Magnetite Nanoparticles from Mono- and Bimetallic Oleates: The Impact of Zn Content, Fe Vacancies, and Morphology on Magnetic Hyperthermia Performance
(ACS American Chemical Society Publications, 2021-04-19)
The currently existing magnetic hyperthermia treatments usually need to employ very large doses of magnetic nanoparticles (MNPs) and/or excessively high excitation conditions (H × f > 1010 A/m s) to reach the therapeutic ...
A Machine Learning Approach to Perform Physical Activity Classification Using a Sensorized Crutch Tip
(IEEE, 2020-11-24)
[EN] In recent years, interest in monitoring Physical Activity (PA) has increased due to its positive effect on health. New technological devices have been proposed for this purpose, mainly focused on sports, which include ...
A Fail-Operational Control Architecture Approach and Dead-Reckoning Strategy in Case of Positioning Failures
(MDPI, 2020-01-13)
[EN] Presently, in the event of a failure in Automated Driving Systems, control architectures rely on hardware redundancies over software solutions to assure reliability or wait for human interaction in takeover requests ...
Extended Enolates: Versatile Intermediates for Asymmetric C-H Functionalization via Noncovalent Catalysis
(Wiley, 2021)
Catalyst-controlled functionalization of unmodified carbonyl compounds is a relevant operation in organic synthesis, especially when high levels of site- and stereo-selectivity can be attained. This objective is now within ...
