A methodology based on sructural finite element Method-Boundary element method and acoustic boundary element method models in 2.5D for the prediction of reradiated noise in Railway-Induced Ground-Borne vibration problems
(2019-06-01)
Article
Restricted access - publisher's policyThis work is focused on the analysis of noise and vibration generated in underground railway tunnels due to train traffic. Specifically, an analysis of noise and vibration generated by train passage in an underground simple ... -
Friction capabilities of graphite-based lubricants at room and over 1400 K temperatures
(2019-01-02)
Article
Restricted access - publisher's policyThe present work investigates the lubricant capabilities at room and hot-forging temperatures (>1400 K) of three types of lubricants with two different graphite concentrations (8% and 12%). These lubricants are distinguished ... -
The effect of plate design, bridging span, and fracture healing on the performance of high tibial osteotomy plates
(2018-12-03)
Article
Open AccessObjectives Opening wedge high tibial osteotomy (HTO) is an established surgical procedure for the treatment of early-stage knee arthritis. Other than infection, the majority of complications are related to mechanical ... -

Model based on an effective material-removal rate to evaluate specific energy consumption in grinding
(Multidisciplinary Digital Publishing Institute (MDPI), 2019-03-21)
Article
Open AccessGrinding energy efficiency depends on the appropriate selection of cutting conditions, grinding wheel, and workpiece material. Additionally, the estimation of specific energy consumption is a good indicator to control the ... -
Analysis of friction coupling and the Painlevé paradox in multibody systems
(2019-03)
Article
Restricted access - publisher's policyMultibody models are useful to describe the macroscopic motion of the elements of physical systems. Modeling contact in such systems can be challenging, especially if friction at the contact interface is taken into account. ... -
Lifetime, cost and fuel efficiency in diesel projects for rural electrification in Venezuela
(2018-10-01)
Article
Restricted access - publisher's policyFrom 2000–2016, 600 million people in developing countries accessed electricity through fossil-fuel-based technologies, both in isolated and grid-connected schemes. Although an increase in the use of renewable energy sources ... -
Formative evaluation of sustainability in rural electrification programs from a management perspective: A case study from Venezuela
(2018)
Article
Restricted access - publisher's policyNowadays, around 1.2 billion people remain without access to electricity in rural areas of Africa, Asia and Latin America. In order to achieve universal access, a wide range of institutions must be involved in long-term ... -
Sustainability and design assessment of rural hybrid microgrids in Venezuela
(2018)
Article
Restricted access - publisher's policyNowadays, 1.2 billion people lack access to electricity, mainly in rural areas of developing countries. In particular, 22 million people do not have electricity in Latin America and many governments are developing rural ... -
Development of a patients-specific 3D-printed preoperative planning and training tool, with functionalized internal surfaces, for complex oncologic cases
(2019)
Article
Restricted access - publisher's policyThe use of physical 3D models has been used in the industry for a while, fulfilling the function of prototypes in the majority of cases where the designers, engineers and manufacturers optimize their designs before taking ... -
Current-induced ductility enhancement of a Magnesium alloy AZ31 in uniaxial micro-tension below 373 K
(Multidisciplinary Digital Publishing Institute (MDPI), 2018-12-31)
Article
Open AccessThe size effects in metal forming have been found to be crucial in micro-scale plastic deformation or micro-forming processes, which lead to attenuation of the material’s formability due to the increasing heterogeneity of ... -
Short-cut method to assess a gross available energy in a medium-load screw friction press
(Multidisciplinary Digital Publishing Institute (MDPI), 2018-03-10)
Article
Open AccessThe present study proposed a rapid method, based on a previous universal compression tests, to estimate the required load capacity to cold forge different specimen quantity in a screw press. Accordingly, experimental and ...
