Five MegawattWind Turbine Power Output Improvements by Passive Flow Control Devices
(MDPI, 2017-06)
The effects of two types of flow control devices, vortex generators (VGs) and Gurney flaps (GFs), on the power output performance of a multi-megawatt horizontal axis wind turbine is presented. To that end, an improved blade ...
Multioperation capacity of parallel manipulators basing on generic kinematic chain approach
(Elsevier, 2017-06-07)
The idea of designing multioperation mechanisms capable of performing different tasks has gained prominence in the last years. These mechanisms, commonly called reconfig- urable mechanisms, have the ability to change their ...
Parallel manipulators: practical applications and kinematic design criteria. Towards the modular reconfigurable robots
(Springer, 2017-06-10)
Modern robotic manipulators play an essential role in industry, developing several tasks in an easy way, enhancing the accuracy of the final product and reducing the executing time. Also they can be found in other fields ...
A novel procedure to determine the cohesive law In DCB tests
(Elsevier, 2017-11-10)
A novel method is presented for the determination of mode I cohesive law for the characterization of delamination in unidirectional carbon fiber reinforced polymer laminates. The energy release rate as a function of the ...
Friction torque in four-point contact slewing bearings: applicability and limitations of current analytical formulations
(Elsevier, 2017-11)
The friction torque is a key parameter in the design of slewing bearings. The most challenging issue in its calculation
resides in the modelling of rolling element contact mechanics. In this manuscript two models for the ...
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 ...
Analysis of the DCB test of angle-ply laminates including residual stresses
(Elsevier, 2017-03-14)
[ES] Se propone un nuevo método para obtener la tasa de liberación de energía mediante la prueba de doble viga en voladizo para laminados de capas angulares. Se estudian dos secuencias diferentes, simétrica y antisimétrica. ...
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 ...
