A Context-Aware Oil Debris-Based Health Indicator for Wind Turbine Gearbox Condition Monitoring
(MDPI, 2019-09-02)
One of the greatest challenges of optimising the correct operation of wind turbines is detecting the health status of their core components, such as gearboxes in particular. Gearbox monitoring is a widely studied topic in ...
Review of Systems Engineering (SE) Methods and Their Application to Wave Energy Technology Development
(MDPI, 2020-10-20)
The design of effective and economically viable wave energy devices involves complex decision-making about the product based on conceptual design information, including stakeholder requirements, functions, components and ...
Influence of Butterfly and Gate Valves Upstream Large Water Meters
(MDPI, 2020-09-14)
The research presented was conducted to quantify the effects of butterfly and gate valves located upstream water meters with diameters larger than 50 mm. Errors caused by these valves can have an enormous financial impact ...
Calibration of Reanalysis Data against Wind Measurements for Energy Production Estimation of Building Integrated Savonius-Type Wind Turbine
(MDPI, 2020-12-17)
In this work, a cost-effective wind resource method specifically developed for the ROSEO-BIWT (Building Integrated Wind Turbine) and other Building Integrated Wind Turbines is presented. It predicts the wind speed and ...
Optical Tip Clearance Measurements as a Tool for Rotating Disk Characterization
(MDPI, 2017-01)
An experimental investigation on the vibrational behavior of a rotating disk by means of three optical fiber sensors is presented. The disk, which is a scale model of the real disk of an aircraft engine, was assembled in ...
Analysis of Alpha Activity Levels and Dependence on Meteorological Factors over a Complex Terrain in Northern Iberian Peninsula (2014–2018)
(MDPI, 2020-10-29)
Alpha ambient concentrations in ground-level air were measured weekly in Bilbao (northern Spain) by collecting aerosols in filters between 2014 and 2018. Over this period, the alpha activity concentrations in the aerosol’s ...
Meteorological Factors Controlling 7Be Activity Concentrations in the Atmospheric Surface Layer in Northern Spain
(MDPI, 2020-12-10)
This work presents the analysis of weekly 7Be activity concentrations in the air measured in Bilbao (northern Spain) by collecting aerosols in filters over a ten years period (2009–2018). 7Be level is in the 0.35–7.3 mBq/m3 ...
Classification and categorization of the constrained environments in nuclear/radiological installations under decommissioning and dismantling processes
(Pergamon-Elsevier, 2020-06)
INSIDER is an EU Horizon 2020 research project, within the topic NFRP-7 of the EURATOM programme, that aims to develop and validate a new and improved integrated characterization methodology and strategy for the nuclear ...
Pitch Angle Misalignment Correction Based on Benchmarking and Laser Scanner Measurement in Wind Farms
(MDPI, 2018-12-01)
In addition to human error, manufacturing tolerances for blades and hubs cause pitch angle misalignment in wind turbines. As a consequence, a significant number of turbines used by existing wind farms experience power ...
Evaluating Equity and Inclusion in Access toWater and Sanitation for Persons Living with HIV/AIDS in Wukro, Ethiopia
(MDPI, 2018-09)
For more than a decade, foreign aid-supported water interventions focusing on an increase in household private connections have been implemented in the small urban center of Wukro. However, little has been investigated ...
