A multidisciplinary sustainability index to assess transport in urban areas: a case study of Donostia- San Sebastian, Spain
(Routledge, Taylor & Francis Group, 2017-03-23)
The management of urban transportation systems represents one of the most
formidable challenges for local government that generates several problems related to
the well-being and the comfort of the public that commute ...
Bond between steel reinforcement bars and electric arc furnace slag concrete
(Springer, 2017-04-21)
This paper deals with the bond between steel reinforcement and recycled aggregate concrete, including Electric arc furnace (EAF) slag as full replacement of natural coarse aggregates. Pull-out tests were carried out according ...
Analysis of the modal choice of transport at the case of university: Case of University of the Basque Country of San Sebastian
(Elsevier, 2017-04-11)
Transportation has significant and long lasting economical, social and environmental impacts, and so is an important dimension of urban sustainability.
Any effort that is made to achieve sustainability must take into ...
Evaluation of efficiency and mechanical properties of Inconel 718 components built by wire and powder laser material deposition

PurposeThe purpose of this paper is to evaluate and compare powder and wire laser material deposition (LMD) processes.Design/methodology/approachIn the present paper, Inconel 718 tensile test probes were built layer by ...
Evaluation of the relevance of melt pool dynamics in Laser Material Deposition process modeling
(Elsevier, 2017-07-14)
The melt pool dynamics consideration in the numeric modeling of the Laser Material Deposition (LMD) process can be enormously difficult and expensive, especially if this calculation is not strictly necessary. The increased ...
Instantaneous powder flux regulation system for Laser Metal Deposition
(Elsevier, 2017-09-04)
A new control system for regulating the powder flux during the laser metal deposition process (LMD) has been designed, developed and validated. The powder regulation system is based on a solenoid, which is coupled to the ...
Equivalent Energy Release Rate And Crack Stability In The End Notched Flexure With Inserted Roller Mixed Mode I/II Test
(Elsevier, 2017-02)
The crack propagation performance of the End Notched Flexure with inserted roller test is analyzed. An equivalent energy release rate is proposed taking into account the interaction of the modes I and II, based on the ...
Microtab design and implementation on a 5MW wind turbine
(MDPI, 2017-05-24)
Microtabs (MT) consist of a small tab placed on the airfoil surface close to the trailing edge and perpendicular to the surface. A study to find the optimal position to improve airfoil aerodynamic performance is presented. ...
Multiple-Criteria Decision-Making Tool for Local Governments to Evaluate the Global and Local Sustainability of Transportation Systems in Urban Areas: Case Study
(ASCE, 2017-10-24)
Efficient management of urban transportation systems is a challenge for any local government that wishes to improve public wellbeing and comfort. With that end in mind, this paper proposes a tool for decision making and ...
Friction torque in four contact point slewing bearings: Effect of manufacturing errors and ring stiffness
(Elsevier, 2017-02-24)
This work outlines a procedure for the determination of the interferences between balls and raceways in four contact
point slewing bearings due to manufacturing errors. The procedure is applied to a particular case and ...
