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
Restricted access - publisher's policyThe 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
Restricted access - publisher's policyIn 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. ... -

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 ... -
Numerical study of Taylor bubbles rising in a stagnant liquid using a level-set/moving-mesh method
(2017-06-08)
Article
Open AccessAn Arbitrary Lagrangian-Eulerian formulation has been posed to solve the challenging problem of the three-dimensional Taylor bubble, within a Conservative Level Set (CLS) framework. By employing a domain optimization method ... -
Nonlinear model predictive control for thermal management in plug-in hybrid electric vehicles
(2017-05)
Article
Open AccessA nonlinear model predictive control (NMPC) for the thermal management (TM) of Plug-in Hybrid Electric Vehicles (PHEVs) is presented. TM in PHEVs is crucial to ensure good components performance and durability in all ... -
