Hybrid nonlinear autoregressive neural network—Weibull statistical model applied to the supercritical extraction of lanolin from raw wool
(Springer, 2020-09-09)
Article
Restricted access - publisher's policySupercritical extraction of lanolin from raw wool with modified CO2 (5% ethanol) at temperatures above the melting point of lanolin (T = 36–42 ºC) is difficult to model because of the multicomponent diffusion in the liquid ... -
Real drive cycles analysis by ordered power methodology applied to fuel consumption, CO2, NOx and PM emissions estimation
(Springer, 2021-01)
Article
Restricted access - publisher's policyIn this work three fuel consumption and exhaust emission models, ADVISOR, VT-MICRO and the European Environmental Agency Emission factors, have been used to obtain fuel consumption (FC) and exhaust emissions. These models ... -
Biological responses of ceramic bone spacers produced by green processing of additively manufactured thin meshes
(Multidisciplinary Digital Publishing Institute (MDPI), 2020-05-30)
Article
Open AccessBone spacers are exclusively used for replacing the tissue after trauma and/or diseases. Ceramic materials bring positive opportunities to enhance greater osteointegration and performance of implants, yet processing of ... -
Study and comparison of the different costs’ schema associated to geometry, material and processing between 3D printing, injection molding and machining manufacturing technologies
(2020-03-09)
Article
Open AccessCost models to assess and compare the level of expenditure incurred when manufacturing a part by applying different production technologies are of big importance for industrial companies. However, the more precise a cost ... -
Versatile image-based measurements of granular flows and water wave propagation in experiments of tsunamis generated by landslides
(2020-04-01)
Article
Open AccessLandslides falling into water bodies can generate destructive waves, which can be classified as tsunamis. An experimental facility to study this phenomenon has been set up. It consists of a landslidegenerator releasing ... -
Effect of grain size and density of abrasive on surface roughness, material removal rate and acoustic emission signal in rough honing processes
(Multidisciplinary Digital Publishing Institute (MDPI), 2019-08-01)
Article
Open AccessHoning processes provide a special cross-hatch pattern to the internal surface of cylinders that favors oil flow. However, along honing operation the abrasive grains wear out and lose their ability to cut material. The ... -
In Vitro Assessment of Bioactive Glass Coatings on Alumina/Zirconia Composite Implants for Potential Use in Prosthetic Applications
(2019-02-08)
Article
Open AccessAchieving the stable osteointegration of prosthetic implants is one of the great challenges of modern orthopedic surgery. The fixation of ceramic acetabular cups of hip joint prostheses is usually achieved using a metal ... -
Numerical approach to study bubbles and drops evolving through complex geometries by using a level set – Moving mesh – Immersed boundary method
(2018-10-01)
Article
Open AccessThe present work proposes a method to study problems of drops and bubbles evolving in complex geometries. First, a conservative level set (CLS) method is enforced to handle the multiphase domain while keeping the mass ... -
Application of the 2D depth-averaged model, FLATModel, to pumiceous debris flows in the Amalfi Coast
(2018-08-29)
Article
Open AccessFew studies about modelling pumice debris flows are available in literature. An integrated approach based on field surveys and numerical modelling is here proposed. A pumiceous debris flow, which occurred in the Amalfi ... -
Assessment of the potential economic impact of the use of AM technologies in the cost levels of manufacturing and stocking of spare part products
(Multidisciplinary Digital Publishing Institute (MDPI), 2018-08-14)
Article
Open AccessAdditive manufacturing (AM) technologies are appropriate manufacturing technologies to produce low rotation products of high added value. Products in the spare parts business usually have discontinuous demand levels of ... -
Acoustic emission analysis for the detection of appropriate cutting operations in honing processes
(2018-01-15)
Article
Open AccessIn the present paper, acoustic emission was studied in honing experiments obtained with different abrasive densities, 15, 30, 45 and 60. In addition, 2D and 3D roughness, material removal rate and tool wear were determined. ... -
Thermal Management in Plug-In Hybrid Electric Vehicles: a Real-Time Nonlinear Model Predictive Control Implementation
(2017-09-15)
Article
Open AccessA real-time nonlinear model predictive control (NMPC) for the thermal management (TM) of the electrical components cooling circuit in a Plug-In Hybrid Electric Vehicle (PHEV) is presented. The electrical components are ...
