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 ... -
Thermal and fluid dynamic analysis of Direct Steam Generation Parabolic Trough Collectors
(Elsevier, 2019-09-15)
Article
Restricted access - publisher's policyDirect Steam Generation (DSG) has attracted considerable attention in comparison with conventional technologies based on Heat Transfer Fluids (HTF) for electricity generation due to its higher temperatures. In this context, ... -
A level-set model for mass transfer in bubbly flows
(2019-08-01)
Article
Restricted access - publisher's policyA level-set model is presented for simulating mass transfer or heat transfer in two-phase flows. The Navier-Stokes equations and mass transfer (or heat transfer) equation are discretized using a finite volume method on a ... -
Environmental impact assessment of sound absorbing nonwovens based on chicken feathers waste
(2019-06-28)
Article
Restricted access - publisher's policyChicken feathers (CFs) are currently a biogenic solid waste generated on a large scale and around the world. Its valorization could provide a great opportunity to manufacture environmentally friendly materials and increase ... -
Water societal metabolism in the Yucatan Peninsula. The impact of climate change on the recharge of groundwater by 2030
(2019-10-20)
Article
Restricted access - publisher's policyThe demographic and economic growth in Yucatan peninsula (YP) in recent years has caused changes in the hydrological response and flow of the water cycle. The growth effects and its impact on society are poorly understood. ... -
Achieving high thermal conductivity in epoxy composites: Effect of boron nitride particle size and matrix-filler interface
(Multidisciplinary Digital Publishing Institute (MDPI), 2019-07-06)
Article
Open AccessFor the thermal management of high watt density circuit layers, it is common to use a filled epoxy system to provide an electrically insulating but thermally conducting bond to a metal substrate. An epoxy-thiol system ... -
An Exploratory Multivariate Statistical Analysis to Assess Urban Diversity
(2019-07-11)
Article
Open AccessUnderstanding diversity in complex urban systems is fundamental in facing current and future sustainability challenges. In this article, we apply an exploratory multivariate statistical analysis (i.e., Principal Component ... -
Maximising the Degree of User Choice: A Simple Tool to Measure Current Levels of Quality of Life in Urban Environments
(2019-06-30)
Article
Open AccessIn this article, we present a simple methodology based on Max-Neef, Elizalde and Hopenhayn (1991) “human scale development” paradigm to measure current levels of Quality of Life (QoL) for urban environments. In this ... -
Structure of force variability during squats performed with an inertial flywheel device under stable versus unstable surfaces
(2019-08)
Article
Restricted access - publisher's policyThe use of unstable surfaces during resistance training has demonstrated a maintenance or reduction on force production. However, the use of unstable surface on force variability has not been assessed using non-linear ... -

(Elsevier, 2019-05-01)
Article
Restricted access - publisher's policyContents lists available atScienceDirectSustainable Cities and Societyjournal homepage:www.elsevier.com/locate/scsLife Cycle Assessment of a solar thermal system in Spain, eco-designalternatives and derived climate change ... -
A review study on the modeling of high-temperature solar thermal collector systems
(2019-09-01)
Article
Restricted access - publisher's policyConcentrated solar power technologies are gaining more attention in the last two decades in order to replace the conventional power technologies and reduce their environmental impact. Among the developed concentrating ... -
A time-average filtering technique to improve the efficiency of two-layer wall models for large eddy simulation in complex geometries
(Elsevier, 2019-06-30)
Article
Restricted access - publisher's policyTwo-Layer wall models have been recurrently studied since they represent a good physical model for Large Eddy Simulations with underresolved wall regions. Specifically, those based on the Reynolds Averaged Navier-Stokes ...
